Calcium reflects total plaque

4. December 2006 William Davis (0)




People frequently ask, "Why measure coronary artery calcium? My doctor said that calcium only tells you if there's hard plaque, and that hard plaque is stable. He/she says that calcium doesn't tell you anything about soft plaque."

Is that true? Is calcium only a reflection of "hard" plaque? Is hard plaque also more stable, less prone to rupture and causes heart attack?

Actually, calcium is a means of measuring total plaque, both soft and hard. That's because calcium comprises 20% of total plaque volume. Within plaque, there may be areas that are soft (labeled "lipid pool" in the diagram). There are also areas made of calcium (shown in white arcs within the plaque). Even though this is just a graphic, it's representative of what is seen when we perform intracoronary ultrasound of a live human being's coronary artery. In other words, this cross section contains both "soft" (lipid pool) as well as "hard" (calcium) elements.

Is this artery "soft" or "hard"? It's both, of course. The artery compostion can vary millimeter by millimeter, having more soft or hard elements. The artery can also change over time in either direction. Thus, "soft" plaque may indeed be soft today, only to be "hard" in 6 months, and vice versa.

The essential point is that measuring just "soft" plaque provides limited information. What the CT heart scan does is provide a gauge of total plaque, soft and hard, and it does so easily, safely, precisely. If your score increases, the lengthwise volume of total plaque has also grown. If your score decreases, the total amount of plaque has also decreased.

Don't mistake marketing for truth

2. December 2006 William Davis (0)
We're all so inundated with marketing messages for food. Unfortunately, many people confuse the messages delivered through marketing with the truth.

For instance:

Pork: "The other white meat." Pork is a high-saturated fat food.

"Bananas: A great source of potassium." Bananas are a high glycemic index (rapid sugar release), low fiber food.

"Pretzels: A low-fat snack." A high glycemic index food made from white wheat flour. It makes you fat and skyrockets blood sugar.

Jif peanut butter: "Choosy moms choose Jif." Do they also choose hydrogenated fats?

Hi-C: Upbeat jingles like "Who put the straw in my Hi-C fruit drink, a new cool straw that wriggles and bends? Who put the straw in my Hi-C fruit drink, with Vitamin C for me and my friends? Who was that man, I'd like to shake his hand, he made my Hi-C cooler than before!" What about the 25 grams of sugar per 4 oz serving? And the high fructose corn syrup that creates an insatiable sweet tooth, raises triglycrides 30%, and exagerates pre-diabetes?


Marketing is not reliable, unbiased information. If Ford boasts that their cars are superior to GM, do you say "Well then, I need to buy a Ford?" Of course not. Take marketing for what it is: A method of persuading people to buy. It may or may not contain the truth. It's a big part of the reason Americans are the fattest people on earth and are experiencing an explosion of chronic diseases of excess.

Tattered Red Dress

1. December 2006 William Davis (0)
"Are you taking your health to heart? Perhaps you understand the importance of eating a diet low in cholesterol or getting 30 minutes of exercise a day. But do you know your own risk of developing cardiovascular disease?


It’s time to take your heart health personally. Heart disease is the No. 1 killer of American women — and that means it is not “someone else’s problem.” As a woman, it’s your problem.

That’s where the Go Red Heart Checkup comes in. This comprehensive evaluation of your overall heart health can help you now and in the future. By knowing your numbers and assessing your risks now, you can work with your doctor to significantly reduce your chances of getting heart disease tomorrow, next year, or 30 years from now!"


So reads some of the materials promoted by the American Heart Association Red Dress campaign to increase awareness of heart disease in women. The effort is well-intended. There is no doubt that most women are unaware of just how common coronary disease is in females.

But I've got a problem with the solutions offered. "Know your numbers"? Eat healthy, don't be overweight, be active, don't smoke. That's the gist of the program's message--nothing new. In 2006, why would some sort of screening effort for detectin of heart disease not be part of the message? Why isn't there any message about the real, truly effective means to detect hidden heart disease in women--namely, heart scanning?

Does a 58-year old woman with normal blood pressure, LDL 144, HDL 51, 20 lbs overweight have hidden heart disease? I've said it before and I'll say it again: You can't tell from the numbers. She could die of a heart attack tomorrow without warning, or maybe she'll be dancing on our graves when she's 95 and never have experienced any manifestation of heart disease. The numbers will not tell you this.

I'm glad the American Heart Association has seen fit to invest its sponsors' money in a campaign to promote prevention. I wish they hadn't fallen so far short of a truly helpful message. Perhaps the sponsors (like Pfizer, maker of Lipitor) will benefit, anyway.

Panic in the streets

29. November 2006 William Davis (0)
Several days ago, I wrote about a local prominent judge in my neighborhood who was unexpectedly found dead in bed of a heart attack at age 49.

As expected, I've received multiple calls from patients and physicians who want heart catheterizations. For instance, an internist I know called me in a panic. He asked that I perform a heart catheterization in a patient with a heart scan score of 768. I've been seeing this patient for about a year. He's without symptoms, even with strenuous exercise; stress tests (i.e., tests of coronary bloow flow) have been normal.

I remind patients and colleagues every day, day in day out: Having a heart scan score revealing some measure of coronary plaque is not a sufficient reason by itself to proceed with procedures. Fear of suffering a fate like the unfortunate judge is also not a reason to proceed with procedures.

Increased awareness of the gravity of heart disease is a good thing. Some good can come out of a needless tragedy like this. The lesson from the judge's unfortunate experience: he needed a CT heart scan. I'm told that the judge's doctor advised him that a heart scan was a waste of time. I hope that appropriate legal action for negligence is taken by the judge's family against this physician.

Not doing a heart scan is wrong. That's the lesson to learn. The lesson is not that everybody with coronary plaque needs a procedure. Had the judge undergone a simple heart scan, intensified prevention could have been instituted and he'd still be alive with his wife and children today.

The indications for procedures are unchanged by your heart scan. If a stress test is abnormal and indicates poor flow to a part of the heart, that would be a reason. If symptoms like chest discomfort or breathlessness appear, that's an indication. If there's evidence of poor heart muscle contraction, that's a reason to proceed with a procedure. But just having coronary plaque is not a sufficient reason.

Heart scan curiosities 1

27. November 2006 William Davis (3)
Heart scans often reveal more than coronary plaque. From time to time, I'll show some curious findings that people have displayed during routine heart scans.

This 65-year old man had a relatively low heart scan score of 73, but showed an impressive quantity of calcification of his pericardium, the usually soft-tissue sack that encases the heart. The calcified pericardium is the white arcs that surround the heart in the center of the image.



Thankfully, because he's without any symptoms of breathlessness, excessive fatigue, or leg swelling, he won't need to have it surgically corrected. When the pericardium becomes rigid and encircles the heart, it can literally squeeze the heart, a condition called "constrictive pericarditis". The surgery is pretty awful.

This man's calcified pericardium likely resulted from one or more viral infections over his lifetime.

Annual physical

26. November 2006 William Davis (0)
A judge who lives in my neighborhood was found dead in his bed this week from a heart attack. He was 49 years old. His teenage kids found him and performed CPR, but he was cold and long-gone by then.

A close friend of the judge told me that he'd passed an annual physical just weeks before.

This sort of tragedy shouldn't happen. It is easily--easily--preventable. Had this man undergone a heart scan, a score of at least 400 if not >1000 would have been uncovered, and appropriate preventive action could have been taken. The conversation could have centered around the strategies to correct the patterns that triggered his plaque and how he could reduce his score.

Of course, hospitals make use of stories like this to fuel fear that brings hordes to their wards for procedures. Would the judge have required a procedure to save his life, had his heart disease been diagnosed at his annual physical? Not necessarily. Hospitals and cardiologists would try to persuade you that procedures have an impact on mortality. This is simply not true. In fact, the mortality benefits of procedures are questionable except in the midst of acute illness (e.g., unstable chest pain symptoms or heart attack).

Don't be falsely reassured by passing a physical. A physical does nothing to screen you for heart disease. An EKG and stress test, if included, is a lame excuse for heart disease screening. Remember that a stress test is a test of coronary blood flow, not for the presence of coronary plaque. The unfortunate judge most likely had a 30% "blockage" that did not block flow, but ruptured and closed an artery off sometime in the night when he died. A stress test even on the day of his death would not have predicted this.

A CT heart scan would have uncovered it easily, unequivocally, safely.

A curious case of regression

25. November 2006 William Davis (0)
Randi came to me at age 43. Before I'd met her, she'd undergone two heart scans about one year apart. The initial score was 57--not terribly high, but very high for a 41-year old, pre-menopausal female. Recall that rarely do women have any heart scan score above zero before age 50. Randi's 2nd scan had yielded a score of 72, a 27% increase.

Randi even had her lipoproteins assessed and she had the dreaded Lp(a). So when I met her, we discussed the possible choices in Lp(a) treatment: niacin and estrogens as primary treatment, along with LDL reduction to rock-bottom numbers, along with adjunctive DHEA, almonds, ground flaxseed, and fish oil. Sandi was okay with the adjunctive treatments and was already slender and active (BMI <25), and did not show Lp(a)'s evil partner, small LDL. But Randi had no interest in estrogens, even bio-identical preparations, because of the usual uncertainties associated with estrogen replacement. She also proved to be one of the people truly intolerant to anything but the most minute dose of niacin, experiencing prolonged flushing and abdominal cramps with any dose >250 mg.

Randi even attempted a trial of the Mathias Rath concoction of high-dose vitamin C, lysine, and proline as treatment for Lp(a), but we saw no effect on Lp(a).

Unfortunately, this left Randi's Lp(a) essentially uncorrected. Another scan one year later: 90, another 25% increase. 18 months after that, another scan: 120, a 30% increase.

Now 47-years old, Randi had resigned herself to not being able to control her plaque. We'd run out of options. At that point, I'd started to have everyone's vitamin D blood level assessed and then replaced with vitamin D. I did this with Randi, too.

A year after her last scan, she underwent another. The score: 92, a 23% reduction--substantial reversal following a course of unrelenting progression.

Randi and I, of course, both rejoiced with this unexpected success. But it raised some interesting questions: How important is Lp(a) when vitamin D is normalized and small LDL is not a part of the picture? How consistent with regression be with this strategy over time? Would normalization of vitamin D have stopped plaque from becoming established in the first place?

I hope these issues will clarify over time. For now, I'm thrilled with Randi's success. She remains on her present, "incomplete", though successful program.

Note: I would not ordinarily advise a young woman to undergo serial heart scanning with this frequency. Randi had unusual access to a scan center through a relationship with the staff. I am nonetheless grateful for the lessons her experience have taught us.

Fortune teller

25. November 2006 William Davis (0)
Whenever your doctor uses your cholesterol values--total, LDL, HDL, triglycerides--to judge your heart disease risk, he/she is trying to act as your fortune teller.

In some states, fortune telling is illegal, a misdemeanor. The New York State lawbooks say:

A person is guilty of fortune telling when, for a fee or compensation which he directly or indirectly solicits or receives, he claims or pretends to tell fortunes, or holds himself out as being able, by claimed or pretended use of occult powers, to answer questions or give advice on personal matters or to exorcise, influence or affect evil spirits or curses; except that this section does not apply to a person who engages in the aforedescribed conduct as part of a show or exhibition solely for the purpose of entertainment or amusement.
(Source : Wikipedia)

Rather than occult powers, your physician claims to use "medical judgement" to tell your fortune. Except for that distinction, it might be construed as a misdemeanor.


Let's take three typical examples:

58-year old Laura has a high LDL of 195 mg/dl. Her HDL is 52 mg/dl, triglycerides 197 mg/dl. Does she have heart disease?

51-year old Jonathan has an LDL of 174 mg/dl, HDL 34 mg/dl, triglycerides 156 mg/dl. Does Jonathan have heart disease?

71-year old Marian has an LDL cholesterol of 135 mg/dl, HDL 84 mg/dl, triglycerides of 67 mg/dl.

None of the three have symptoms. They all feel well. Nobody is taking a statin cholesterol drug or other agent that would modify the numbers. Jonathan is around 30 lbs overweight. Nobody has an impressive family history of heart disease.

Can you tell who has heart disease and who doesn't? If you can, you're smarter than I am, because I certainly can't tell. But your doctor tries to divine your future by looking at these numbers.

Do they know something that we don't know? No. It's a crude odds game, a guessing game. A guessing game that frequently comes up on the losing end.

These are three real people. Laura, despite her high LDL, has no identifiable coronary heart disease. Jonathan has advanced coronary disease. These were his numbers just prior to his stent. Marian has a moderate quantity revealed by a CT heart scan score of 419.

Don't even try predicting your future from your cholesterol numbers--it simply can't be done. Every day, I see patients and physicians beating their heads over this dilemma. Telling your fortune using pretended occult powers is illegal. Telling your fortune using cholesterol numbers should be, too.

If you want to know if you have coronary plaque, that's the role of the CT heart scan. Plain and simple.

Heart scan score drops like a stone

23. November 2006 William Davis (2)
Matt was dumbfounded when he found out about his heart scan score of 317 in the summer of 2005.

Earlier that year he'd unintentionally lost 20 lbs. in the space of two months and was feeling awful. He was diagnosed with diabetes and put on several medications. He told me that the heart scan score was just adding insult to injury.

As you'd expect in someone with diabetes, Matt had a low HDL, increased triglycerides, and small LDL. Blood pressure and inflammation (C-reactive protein) were issues as well.

Matt's primary care physician had put him on a statin cholesterol drug as soon as he heard about Matt's heart scan score, so we kept this going. What Matt's primary care physician didn't know was that his "true" LDL had been much higher than the conventional calculated LDL had suggested, so the statin agent was a reasonable solution. (Matt was also not terribly motivated to make dramatic changes in lifestyle or food choices. The statin drug was a compromise.)

We added fish oil and vitamin D to his regimen. Though recent data have cast doubt on the value of treating homocysteine levels of around 12.5, Matt's much higher value of 28 was treated with vitamins B6, B12, and folic acid, with a resultant homocysteine of 7.6.

17 months into the Track Your Plaque approach, and Matt's repeat heart scan score: 244, a 23% reduction.

How's that for an early Christmas gift?

"You don't have a uterus. You don't need progesterone"

21. November 2006 William Davis (2)
I was talking with a hospital nurse recently who told me about her lack of energy, blue moods, and other assorted complaints. At age 49, she was exasperated. So I suggested that she ask her gynecologist about progesterone cream.

The gynecologist advised her, "You don't have a uterus. You don't need progesterone." He went on to explain that the only reason to take progesterone was to prevent uterine cancer caused by estrogen.

Then what about progesterone's weight loss benefits? It's effects on increased energy, improved mood, deeper sleep? These benefits, of course, have nothing to do with the uterus.

I've witnessed these benefits in women many times, both in the peri-menopausal period (which starts around your late 30's) and menopause.

Why talk about progesterone when our focus is heart disease and reduction of heart scan scores? Because if progesterone in a woman helps her feel better, more upbeat, and accelerates weight loss, she's more likely to succeed in her plaque-control program.

For additional comments on progesterone, read the Track Your Plaque interview with women's hormone expert, Dr. Nisha Jackson, Females, hormones, and weight control:

Stents, defibrillators, and other profit-making opportunities

16. April 2006 William Davis (2)
As a practicing cardiologst, every day I receive a dozen or more magazines or newspapers targeting practicing physicians, not to mention the hundreds of letters, postcards, invitations to "talks", etc. that I receive. All of these materials share one common goal: To get the practicing cardiologist/physician to insert more of a manufacturer's stents, defibrillators, prescribe more of their drugs, etc.

This is a highly effective and profitable area. Pfizer's Lipitor, for instance, generated $12.2 billion just last year alone. This kind of money will fund an extraordinary amount of marketing.

I'm on the www.heart.org mailing list, a website for cardiologists. I'd estimate that 90% or more of their content is device-related: discussions of situations in which to insert stents, the expanding world of implantable devices, the ups and downs of various drugs. Rarely are discussions of healthy lifestyles, exercise, nutritional supplements, part of the dialogue.

How can you protect yourself from the brainwashed physician, flooded with visions of all the devices he can put in you, all the drugs that can "cure" your disease? Simple: information. Be better informed. Ask pointed questions. The idiotic lay press tells you to ask a doctor about his education. That's not generally the problem. Some of the best educated doc's I know are also the most flagrantly guilty of profiteering medicine.

Ask your doctor about his/her philosphy about the use of medications, devices, etc. If their word is God, take it or leave it, run the other way.

Will radiation kill you?

16. April 2006 William Davis (4)
Several people have asked me lately if radiation is truly dangerous. These conversations were sparked by an editorial comment made on a column I wrote for Life Extension Magazine's April, 2006 issue on "Three ways to detect hidden heart disease".

Among the methods that were discussed in this piece was, of course, CT heart scanning. Anyone who is involved with CT heart scans Quickly recognizes the spectacular power of this test to uncover hidden, unsuspected heart disease, literally within seconds. In 2006, there's really nothing like it for the every day person to have hidden heart disease detected and precisely quantified.

Yet, the "rebuttal" to my article claimed that the broad use of heart scans was only my personal view and that, in truth, radiation kills people.

NONSENSE! If an ovarian cancer is discovered by a CT scan of the abdomen, is that unwise use of radiation? If pneumonia or lung cancer is discovered on a chest x-ray with minimal radiation exposure, have we performed a disservice. Of course not. In fact, these are often lifesaving applications of radiation.

Can radiation be used unwisely with excessive exposure? Of course. The 64 slice CT angiograms are just an example of this. Dr. Mehmet Oz announced on Oprah recently that this was a test to be used for broad screening of women for heart disease. This is wrong. The radiation required for a full 64 slice CT angiogram test is truly excessive for a screening application. You wouln't want to get breast cancer from your mammogram, would you? The radiation from a 64-slice CT angiogram is similar to that of a heart catheterization in the hospital--too much for screening. This is not to be confused with a CT heart scan for a calcium score performed on a 64 slice device. I think this can be performed with acceptable radiation exposure.

Think about what would happen, for instance, if you had your heart disease undetected, had a heart attack, and went to the hospital? During your hospitalization, you'd likely get five chest x-rays, a heart catheterization, perhaps one or more nuclear imaging tests, maybe even a full CT scan (with far more radiation than a screening heart scan). The amount of radiation of a heart scan is trivial compared to what you obtain in a hospital.

So take it all in perspective. The low level of radiation required for a simple heart scan (not an angiogram) does not by itself substantially add to your lifetime risk of radiation exposure. It may, in fact, save your life or reduce your life long exposure to radiation.

Are you using bogus supplements?

16. April 2006 William Davis (0)
I consider nutritional supplements an important, many times a critical,part of a coronary plaque control program.

But use the wrong brand or use it in the wrong way, and you can obtain no benefit. Occasionally, you can even suffer adverse effects.

Take coenzyme Q10, for instance. (Track Your Plaque Members: A full, in-depth Special Report on coenzyme Q10 will be on the website in the next couple of weeks.) Take the wrong brand to minimize the likelihood of statin-related muscle aches, and you may find taking Lipitor, Zocor, Crestor, etc. intolerable or impossible. However, take a 100 mg preparation from a trusted manufacturer in an oil-based capsule, and you are far more likely to avoid the inevitable muscle aches. (Though, of course, consult with your doctor, for all it's worth, if you develop muscle aches on any of these prescription agents.)

Unfortunately, you and I often don't truly know for a fact if a bottle from the shelf of a health food store or drugstore is accurately labeled, pure, free of contaminants, and efficacious.

One really great service for people serious about supplements is the www.consumerlab.com website. They are a membership website (with dues very reasonable) started by a physician interested in ensuring supplement quality. Consumer Lab tests nutritional supplements to determine whether it 1) contains what the label claims, and 2) is free of contamination. (I have no reason to pitch this or any other site; it's just a great service.) They recently found a supplement with Dr. Andrew Weil's name on it to have excess quantities of lead!

What Consumer Lab does not do is determine efficacy. In other words, they do a responsible job of reporting on what clinical studies have been performed to support the use of a specific supplement. However, true claims of efficacy of supplement X to treat symptom or disease Y can only come with FDA approval. Supplements rarely will be put through the financial rigors of this process.

If you're not a serious supplement user, but just need a reliable source, we've had good experiences with:

--GNC--the national chain
--Vitamin Shoppe--also a national chain
--www.lifeextension.com or www.lef.org--A great and low-priced source, but they do charge a $75 annual membership that comes with a subscription to their magazine, Life Extension (which I frequently write for) and several free supplements that you may or may not need. Again, I'm not pitching them; they are simply a good source.
--Solgar--a major manufacturer
--Vitamin World
--Nature's Bounty
--Sundown

There are many others, as well. Unfortunately, it's only the occasional manufacturer or distributor that permits unnacceptable contamination with lead or other poisons, or inaccurately labels their supplement (e.g., contains 1000 mg of glucosamine when it really contains 200 mg). I have not come across any manufacturer/distributor who has systemtically marketed uniformly bad products.

It really helps to have someone to lean on

16. April 2006 William Davis (0)
Among my patients are several husband and wife teams, both of whom have heart disease by some measure. Several couples, for instance, consist of a huband who's received a stent, survived a heart attack, or has some other scar of the conventional approach. The wives generally have a substantial heart scan score in the several hundred range.

There are a few couples for which the roles are reversed: wife with bypass, heart attack, etc. and husband with a substantial quantity of coronary plaque by CT heart scan.

From them all, however, I've learned the power of teamwork. When both wife and husband (or even "significant other") are committed to the effort of controlling or reversing heart disease risk, the likelihood of success is magnified many-fold. Everything is easier: shopping for and choosing foods, incorporating supplements in the budget, taking vacations with a healthy focus, following through and sticking with your program.

Several of the couples have succeeded in obtaining regression of plaque for both man and woman. Both have reduced their heart scan scores and, as a result, dramatically reduced the potential for future heart attack and procedures.

Unfortunately, I will also see the opposite situation: One spouse committed to the program but the other indifferent. They may say such things as "You can't control what happens in the future." Or, "There's no way you can get rid of risk for heart disease. My doctor says it's hereditary." Or, "I've eaten this way since I was a kid. I'm not changing now for you or for anybody else."

Such negative commentary can't help but erode your commitment to health. Most of us recognize these sorts of comments as self-fulfulling and self-defeating.

What should you do if you have an unsupportive partner? Not easy. But it really can help to seek out a supportive partner, whether it's a friend, relative, or other significant person in your life. Of course, not everybody can find such a person. Perhaps that's another way our program can help.

I'd like to hear from anyone who does obtain substantial support of someone close, or if you are struggling to do so.

Five foods that can booby trap your heart disease prevention program

14. April 2006 William Davis (0)
There are several foods that commonly come up on people's lists of habitual foods that are truly undesirable for a heart disease prevention program. Curiously, people choose these foods because of the mis-perception that they are healthy. My patients are often shocked when I tell them that they are not healthy and are, in fact, detrimental to their program.

I'm not talking about foods that are obviously unhealthy. You know these: fried foods, greasy cheeseburgers, French fries, bacon, sausage, etc. Nearly everyone knows that the high saturated fat content, low fiber, and low nutritional value of these foods are behind heart disease, hypertension, and a variety of cancers.

I'm talking about foods that people say they eat because they view them as healthy--but they're not.

Here's the list:

1) Low-fat or non-fat salad dressings--Virtually all brands we've examined have high-fructose corn syrup as one the main ingredients. What does high fructose corn syrup do? Triggers sugar cravings, makes your triglycerides skyrocket (causing formation of abnormal lipoproteins like small LDL), and causes diabetes. The average American now ingests nearly 80 lbs of this evil sweetener per year. You're far better off with olive, canol, grapeseed, or flaxseed based salad dressings.

2) Breakfast cereals--If you've been following these discussions, you know that the majority of breakfast cereals are sugar. They may not actually contain sugar, but they contain ingredients that are converted to sugar in your body. They may be cleverly disguised as healthy--Raisin Bran, Shredded Wheat, etc.

3) Pretzels--"A low-fat snack". That's right. A low-fat snack that raises blood sugar like eating table sugar from the bowl.

4) Margarine--Forget this silly argument about which is worse, butter or margarine. Which is worse, strychnine or lead? Both are poisons to the human body. Who cares which is worse? Fortunately, there are now healthy "margarines" like Smart Balance and Benecol that lack the saturated fat or hydrogenated fat of either.

4) Bananas--Bananas are not all that intrinsically unhealthy. The problem is that people will say to me, "Oh sure, I eat fruit. Two bananas a day." What I hear is "I don't really eat fruit with high nutrient value, fiber, and reduced sugar release. I reach for only bananas which yield extreme sugar rises in my blood and are low fiber." Aren't they high in potassium? Yes, but there are better sources. Cut back if you are a banana freak.


Why the mis-perceptions? A holdover from the low-fat diet days and marketing from food manufacturers are the principal reasons. Of course, foods are meant to be enjoyed, but be informed about it. Choose foods for the right reasons, not because of some cleverly-crafted marketing campaign.

Breakfast of champions?

12. April 2006 William Davis (1)
I spend time every day educating or reminding patients that breakfast cereals are not health foods.

I see jaws drop in shock when I tell them that, in my opinion and despite the marketing claims, Cheerios, Raisin Bran, Shredded Wheat, and the like do not yield health benefits. In fact, they do the the opposite: dramatically raise blood sugar and trigger an adverse cascade of events that eventually leads to diabetes and heart disease.

Why the health claims in advertising? Because these products contain insoluble fiber, the sort that makes your bowels regular. Yes, your bowels are important to health, too. But the benefits end there.

Breakfast cereals are a highly refined, processed food that are not good for your plaque control program. What they are is a highly profitable, multi-billion dollar business, deeply entrenched in American culture ("They'rrrre grrrrrreat!"--Tony the Tiger; "There's a whole scoop of raisins in every box of Post Raisin Bran!" Bet you remember them all.)

I find it particularly upsetting when I see the stamp of approval from the American Heart Association on some products. Gee, if the Heart Association says it's good for you, it must be true! Don't you believe it. The American Heart Association relies on corporate donations, just like any other charity.

If you must eat breakfast cereals, refer to www.glycemicindex.com for a full database of glycemic indexes. You can look up a specific product and it will list its glycemic index, or sugar-releasing properties. You should try to keep glycemic index of the foods you choose below 50.

For a revealing discussion of the influence of food marketers on our perceptions of food, see Track Your Plaque nutrition expert, Gay Riley's discussion The Marketing of Food and Diets in America at her website, www.netnutritionist.com.

In heart disease prevention, shoot for perfection

12. April 2006 William Davis (0)
It really struck me today that it's the people who've chosen to compromise their prevention program who end up with trouble--heart procedures, heart attack, even heart failure.

Take Bob, for example. Bob is 73 years old and had a bypass operation in 2000. The procedure went well and Bob enjoyed 6 years of seemingly trouble-free life. Bob had a seriously low HDL cholesterol for which he as taken a modest dose of niacin, but was unwilling to do much more. His HDL cholesterol was thererefore "stalled" at around 40 mg. (We aim for 60 mg or greater.) We talked repeatedly about the options for increasing HDL but Bob was content with his results. After all, since his bypass operation, he'd felt well and could do all he wanted without physical limitation.

But Bob underwent a stress test for surveillance purposes (which we routinely do 5 or more years after bypass surgery). The test was markedly abnormal with two major areas of poor blood flow to his heart (signalling potential heart attack in future). Bob ended up getting 5 stents to salvage two bypass grafts, both of which showed signs of substantial degeneration.

I've seen this scenario repeatedly: A person is unwilling to go the extra mile to obtain perfection in lipid/lipoprotein patterns, lifestyle changes, and taking the basic, required supplements. Compromises eventually catch up to you in the form of another heart attack, more procedures, heart failure, physical disability, even death.

The message: Don't draw compromises in heart disease prevention. Coronary plaque is a chronic process. It will take advantage of you if you ever let your guard down.

The epidemic of small LDL

11. April 2006 William Davis (0)
Of the patients I saw in my office yesterday, virtually EVERYONE had small LDL.

Small LDL is emerging as an extraordinarily prevalent lipoprotein pattern that drives coronary plaque growth. Previous estimates have put small LDL as affecting only 20-30% of people with coronary disease. However, in my experience in the last few years, I would estimate that greater than 80% of people with measurable coronary plaque have small LDL.

If you have a heart scan score >zero, chances are you have it, too.

I call small LDL a "modern" disease because it has skyrocketed in prevalence recently because of the great surge in inactivity in Americans.

When's the last time you walked to the grocery store and back, lugging two bags of groceries? How many years has it been since you've push-mowed your lawn? All the small conveniences of life have permeated further and further into our activities. Most of us spend the great majority of our day right where you are now--on your duff.

On the bright side, small LDL in most people is reducable by simply getting up and going. But the old teaching of 30 minutes of activity per day is now outdated. This was true when the other hours of your life included physical activities, like housework or a moderately active job. However, if the other 23 1/2 hours of your day are sedentary, then 30 minutes a day won't do it. An hour or more of activity, whether exercise or physical labor of some variety will get you better small LDL-suppressing results.

For most people with small LDL, fish oil and niacin are also necessary to fully suppress small LDL to the Track Your Plaque goal of <10 mg/dl.

A great discussion on vitamin D

10. April 2006 William Davis (0)
If you need better convincing that vitamin D is among the most underappreciated but crucial vitamins for health, see Russell Martin's review of vitamin D and its role in cancer prevention. You'll find it in March, 2006 Life Extension Magazine or their www.LEF.org website at:

http://search.lef.org/cgi-src-bin/MsmGo.exe?grab_id=0&page_id=1308&query=vitamin%20d&hiword=VITAM%20VITAMER%20VITAMERS%20VITAMI%20VITAMINA%20VITAMINAS%20VITAMINC%20VITAMIND%20VITAMINE%20VITAMINEN%20VITAMINES%20VITAMINIC%20VITAMINK%20VITAMINS%20d%20vitamin%20

Our preliminary experience over the past year suggests that vitamin D may be the crucial missing link in many people's plaque control program. We've had a handful of people who, despite an otherwise perfect program (LDL<60, HDL>60, etc.; vigorous exercise, healthy food selection, etc.--I mean perfect)continued to show plaque growth. The rate of growth was slower than the natural expected rate of 30% per year, but still frightening rates of 14-18% per year--until we added vitamin D. All of a sudden, we saw dramatic regression of 7-25% in 6 months to a year.

This does not mean that vitamin D all by itself regresses plaque. I believe it means that vitamin D exerts a "permissive" effect, allowing all the other treatments (fish oil, LDL reduction, HDL raising, correction of small LDL, etc.) to exert their full benefit. So please don't stop everything and just take D. This will not work. However, adding vitamin D to your program on top of the basic Track Your Plaque approach--that's the best way I know of.

MSNBC Report: We need more heart procedures!

10. April 2006 William Davis (0)
A recent headline from MSNBC by Robert Bazell reads:

NEW YORK - Angioplasty, bypass surgery and cholesterol-lowering medications are among the many interventions that have brought a sharp decrease in heart disease deaths in recent years. But, as Dr. Sharon Hayes of the Mayo Clinic points out, there is one big problem.

“The death rates in women have not declined as much as they have in men,” she says.

The piece goes on to suggest that women are getting short-ended in the diagnosis of heart symptoms and heart attack. The solution: More testing to assess the need for procedures like bypass.

This is typical of the device and medication-dominated media consciousness: More procedures, more medication, more devices. Who's paying for advertising, after all? The money at stake is huge. But is this what you want?

Don't be swayed by media reporters with limited understanding of the real issues (at best), consciousness of who's paying for advertising (at worst). Yes, heart disese is often underestimated or misdiagnosed in women. The answer is better detection earlier in life followed by efforts to halt the process--effective, safe treatments for people's benefit, not just profit.

Grasscutting, fertilizer, and healthcare

25. 八月 2009 William Davis (23)
A guy named Jeff, a 60-something, taciturn, "How 'bout dem Brewers?" kind of guy, cuts my grass.

Once a week, Jeff drives over his rust-rimmed 1994 Chevy pickup and trailer, unloads his ride mower, and cuts the grass. For his 40 minutes of work, I pay him $35.

For $35, all he does is cut the grass--no trimming, no picking up debris, no working in the garden, no fertilizing, no weeding. Just cutting the grass. Occasionally, Jeff has proven to be a useful resource for peculiar problems. Last year, I had a drainage problem that he helped solve and two years ago he helped diagnose a tree disease that was killing a tree in the backyard; it's now recovered.

To save money, and because I like to work in the yard, I do the rest. I trim the edges, I fertilize the grass, plant new flowers and trees, fix damaged areas, trim wild branches.

In my view, my relationship with Jeff, a limited, as-needed relationship, in which I ask him to help with specific issues but I manage the rest myself, is how I believe that healthcare should also be conducted.

Your doctor should be like Jeff: Perhaps not taciturn, but an as-needed resource available while you do much of the work.

My simple relationship with Jeff is, I believe, the healthcare model of the future. You manage your own cholesterol issues, your own basic thyroid issues, supplement and monitor your vitamin D levels, use diet to suit your needs, order blood tests when necessary, even obtain basic imaging tests like heart scans, carotid ultrasound, bone density testing. Your doctor is a resource, near by when and if you need him or her: guidance when needed, an occasional review of what you are doing, someone to consult when you fracture an ankle.

What your doctor is NOT is a paternal, "do what I say, I'm the doctor," or a "You need these tests whether you like it or not" holder of your health fate.

It is a model of healthcare that will evolve over the next 20-30 years, only in its infancy now.

While we started Track Your Plaque as just a resource for in-depth information on prevention and reversal of coronary heart disease, I now see it as something much greater: a prototype for the emerging concept of self-directed health.

Enough for now. I've got some tomatoes to pick.

Iodine deficiency is REAL

21. 八月 2009 William Davis (30)
Like many health-conscious people, Kurt avoids salt. In fact, he has assiduously avoided salt ever since his heart attack back in 1995.

Lately, Kurt had become tired, often for little or no reason. His thyroid panel:

TSH 4.2 mIU/L (0.27-4.20)
Free T3 1.74 pg/ml (2.50-4.30)
Free T4 1.05 ng/dl (0.9-1.7)

Kurt's TSH of 4.2 mIU/L is sufficient to increase LDL cholesterol by 20-30% and increase the (relative) risk for heart attack 3-fold.

Kurt's thyroid was also palpably enlarged. While it was just barely visible--just a minor bulge in the neck (in the shape of a bowtie), it could be clearly felt when I examined him.

I asked Kurt to add 500 mcg of iodine every day. Three months later, another thyroid panel showed:

TSH 0.14 mIU/L (0.27-4.20)
Free T3 2.50 pg/ml (2.50-4.30)
Free T4 1.1 ng/dl (0.9-1.7)

Kurt's thyroid function normalized to nearly ideal levels just with iodine replacement. (The free T3, while improved, remains low; an issue for another day!)

I see this response with some frequency: low-grade goiter and apparent hypothyroidism (low thyroid function) that responds, at least partially, to iodine replacement. In Kurt's case, iodine replacement alone normalized his thyroid measures completely.

With improved thyroid measures, Kurt also felt better with renewed energy and a 22 mg/dl reduction in LDL cholesterol.

Make no mistake: Iodine deficiency is real. While most of my colleagues have dismissed iodine deficiency as a relic of the early 20th century and third world countries, you can also find it in your neighborhood.

Fish oil for $780 per bottle

19. 八月 2009 William Davis (16)
At prevailing pharmacy prices, one capsule of prescription Lovaza fish oil costs $4.33 each.

Yes, you heard right: $4.33 per capsule.

What do you get for $4.33 per capsule? By omega-3 fatty acid content, you get 842 mg EPA + DHA per capsule.

I can also go to Sam's Club and buy a bottle of their Triple-Strength fish oil with 900 mg omega-3 fatty acids per capsule at $18.99 per bottle of 180 capsules. That comes to 10.5 cents per capsule. That puts the price of fish oil from Sam's Club at 97.6% less cost compared to Lovaza for an equivalent quantity of omega-3 fatty acids.

What if we repriced Sam's Club's Triple-Strength and brought it "in line" with what we pay for Lovaza? That would put the value of one bottle of Sam's Club Triple-Strength fish oil at $780 per bottle.

I take patients off Lovaza every chance I get.

Organic really IS better

16. 八月 2009 William Davis (18)
If you have any doubts about the value of organic foods vs. conventionally-grown foods, then take a look at the findings from a USDA--Yes, USDA--sponsored study.

In this study, the nutritional content of organic vs. conventionally-grown blueberries were compared. Ironically, these observations come from the USDA's Genetic Improvement of Fruits and Vegetables Laboratory of the Produce Quality and Safety Laboratory.

Their findings (all values expressed as weight per 100 grams fresh weight blueberries, or a bit less than 1/4 cup):


Total phenol content (e.g, flavonoids):

Organic: 319.3 mg
Conventional: 190.3 mg

Organic blueberries had 68% greater phenol content.


Total anthocyanins (an important class of flavonoids):

Organic: 131.2 mg
Conventional: 82.4 mg

Organic blueberries had 59% greater anthocyanin content.


Antioxidant capacity (ORAC):

Organic: 46.14 mg
Conventional: 30.8

Organic blueberries had 50% greater antioxidant capacity.


Flavonoids suspected to carry unusually potent health effects--malvidin, delphinidin, myricetin, and quercetin--were all contained in greater proportions in the organically-grown blueberries, also. These flavonoids are demonstrating pharmacologic-level health effects in preliminary studies.

Why a genetics laboratory? After all , the study findings came out heavily in favor of non-genetic, organic farming methods of growing produce. It certainly must have at least given pause to the vocal group within agriculture and the USDA that have long argued that organic produce is no different. I suspect that the laboratory will now try to recreate the nutritional value of organic through genetic manipulation of cultivars grown using conventional methods.

Regardless of the motivations behind the study, we see that there is no comparison: organic blueberries are superior in nutritional value to those grown with conventional pesticides and herbicides. While the study addressed only blueberries, the dramatic difference makes it likely that similar differences exist in other fruits and vegetables.

Coming on the Track Your Plaque website: An in-depth Special Report on the health effects of anthocyanins.

Do you really need calcium?

12. 八月 2009 William Davis (0)
Why are we advised to take calcium supplements?

Men and women are advised to take calcium because it has been shown to reduce blood pressure modestly. Women, in particular, can stall the deterioration of bone strength (mineralization) by taking calcium supplements, 1200-1300 mg per day, and eating calcium-rich foods like dairy products.

Is that all true?

It is true insofar as we remain vitamin D deficient. A funny thing happens when you fully replete vitamin D: Intestinal absorption of calcium as much as quadruples. That means your body will efficiently absorb the calcium in broccoli and spinach.

Is it still necessary to force-feed your body megadoses of calcium once vitamin D has been repleted? I don’t think so.

While the evidence is indirect, several observations point towards the lack of necessity of calcium once vitamin D is addressed.
For instance:

Women who take calcium, 1200 mg per day, with vitamin D, 800 units per day, double their five-year risk for heart attack, according to a New Zealand study.

Men who take calcium, 1200 mg per day, with vitamin D, 800 units per day, also may substantially increase heart attack risk.

Bone density increases more with vitamin D than with calcium. Calcium may not even be necessary to increase bone mineralization, since there are data to suggest that vitamin D can accomplish this by itself.

Calcium suppresses parathyroid hormone, PTH. That is, in fact, how calcium stalls (usually does not reverse) bone mineral loss-not by adding calcium to bone, but by suppressing PTH release. (PTH causes bone demineralization.) Vitamin D suppresses PTH to a far greater degree than calcium.

What is needed is a broad reconsideration of the advice everyone is getting to take calcium. In an age when more and more people are appreciating the power of vitamin D supplementation to achieve normal blood levels, there may be danger ahead for those who fail to address their calcium overdosing.

The case against vitamin D2

11. 八月 2009 William Davis (40)
Why would vitamin D be prescribed when vitamin D3 is available over-the-counter?

Let's review the known differences between vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol):

--D3 is the human form; D2 is the non-human form found in plants.

--Dose for dose, D3 is more effective at raising blood levels of 25-hydroxy vitamin D than D2. It requires roughly twice to 250% of the dose of D2 to match that of D3 (Trang H et al 1998).

--D2 blood levels don't yield long-term sustained levels of 25-hydroxy vitamin D as does D3. When examined as a 28-day area under the curve (AUC--a superior measure of biologic exposure), D3 yields better than a 300% increased potency compared to D2. This means that it requires around 50,000 units D2 to match the effects of 15,000 units D3 (Armas LA et al 2004).

--D2 has lower binding affinity for vitamin D-binding protein, compared to D3

--Mitochondrial vitamin D 25-hydroxylase converts D3 to the 25-hydroxylated form five times more rapidly than D2.

--As we age, the ability to metabolize D2 is dramatically reduced, while D3 is not subject to this phenomenon (Harris SS et al 2002).




From Armas LA, Hollis BW, Heaney RP 2004


While there are dissenters on this view, the bulk of evidence suggests that D2 is an inferior form of D3.

Then why is D2 prescribed by many doctors when the natural, human, and superior D3 is available over-the-counter?

You already know the answer: Much of your doctor's education did not come from scientific lectures nor from reading scientific studies. It came from the pretty drug representative in the waiting room who hands the doctor reprints of the "studies" performed by the drug industry to support the use of their drugs. There is no such nutritional supplement representative in the waiting room. This preference for the "drug" D2 over the supplement D3 also stems from the inherent preference of physicians for things they can control, whether or not there is proof of superiority.

In my view, there is absolutely no reason to take vitamin D2 over D3 except to enrich the drug industry.

Honey: More fructose than high-fructose corn syrup

11. 八月 2009 William Davis (21)
Honey: It’s natural. Mom probably gave it to you, either straight or in tea for a sore throat when you were a kid. Even today, honey is touted as possessing almost supernatural qualities for promoting health.

Honey contains B vitamins, minerals, and a handful of antioxidants. It also contains . . . fructose. 60% of honey, in fact, is fructose.

While the average per capita intake of honey is only a modest 1.29 lb per year (National Honey Board; 2008) and therefore contributes only 0.77 lb of fructose per year, there are people who, believing honey to be healthy, use it to excess and use far more than 1.29 lb per year.

How does that compare to table sugar, or sucrose?

Sucrose is 50:50 glucose to fructose. How about high-fructose corn syrup, the sweetener found in virtually all processed foods that has replaced sucrose as the most common sweetener? Depending on the variety, high-fructose corn syrup is generally 42-55% fructose. Many of us (including me) believe that the proliferation of high-fructose corn syrup in processed foods is a big part of the reason Americans are fat and diabetic.

Yes: Judged by its fructose content, honey is worse than high-fructose corn syrup. It is also worse than sucrose.

It means that honey can also contribute to the adverse health effects of fructose, as detailed in this prior Heart Scan Blog post.

Sun, fish, and seaweed

8. 八月 2009 William Davis (9)
Extraordinary heart health springs from three basic sources in our environment:

Sun, fish, and seaweed.

Sun: Sunlight exposure is nature's intended source of vitamin D. Humans were meant to run naked, or at least scantily clad, in tropical or sub-tropical climates. The large surface area of skin ensured plenty of skin activation of vitamin D, along with long days of intense sun (unlike the seasonal variation of day length and less intense sun further north).

Fish: Fish are the principal source of omega-3 fatty acids, as are, to a lesser degree, wild land animals. Humans as hunter-gatherers tracked, captured, and slaughtered fish and wild game, eaten immediately, since there was no means of storage. Omega-3-rich game was the principal source of fat for primitive cultures.

Seaweed: Seaweed is the world’s most concentrated source of iodine. While seafood like fish and shellfish also contain iodine, seaweed contains, on average, a thousand-fold greater quantity. Seaweed, like plants found on land, are also rich in phytonutrients.

The healthiest cultures on earth follow this simple recipe for health. The unhealthiest population on earth-meaning Americans (i.e., without benefit of bail-out medications and procedures that keep us alive, or vaccinations that protect us from infectious diseases)--neglect all three. Witness the Okinawans, whose daily meals nearly always contain some form of fish and seaweed, and whose sub-tropical climate provides greater sun exposure. It is not unusual for Okinawans to live to 100 years of age, not as an exception, but the rule. Heart disease was virtually unknown except in 90-year olds and older-that is, until the recent adoption of Western practices like fast food and snacks.

It's pretty incredible when you think about it: Simple practices can markedly reduce your likelihood of heart attack and developing heart disease.

Perhaps you’d rather not run naked along a semi-tropical beach, spear fish, and gather seaweed. You could always do the modern equivalents and achieve similar benefits.

Fructose is a coronary risk factor

4. 八月 2009 William Davis (21)
As discussed in a previous Heart Scan Blog post, Say Goodbye to Fructose, a carefully-conducted University of California study demonstrated that, compared to glucose, fructose induces:

1) Four-fold greater intra-abdominal fat accumulation

2) 13.9% increase in LDL cholesterol, doubled Apoprotein B

3) 44.9% increase in small LDL, 3-fold more than glucose

4) Increased postprandial triglycerides 99.2%.


Other studies have shown that fructose:

--Increases uric acid--No longer is red meat the cause for increased uric acid; fructose has taken its place. Uric acid may act as an independent coronary risk factor and increases high blood pressure and kidney disease.

--Induces insulin resistance, the situation that creates diabetes

--Increases glycation (fructose linked to proteins) and protein cross-linking, processes that underlie atherosclerosis, liver disease, and cataracts.


Make no mistake: Fructose is a powerful coronary risk factor.
There is no doubt whatsoever that a diet rich in fructose from fruit drinks, honey, raisins and other dried fruit like cranberries, sucrose (table sugar), and high-fructose corn syrup is a high-risk path to heart disease.

Also note that many foods labeled "heart healthy" because of low-fat, low saturated fat, addition of sterol esters, or fiber, also contain fructose sources, especially high-fructose corn syrup.

Take a niacin "vacation"

20. noviembre 2006 William Davis (2)
I've been seeing a curious niacin phenomenon that has not, to my knowledge, been reported anywhere in the medical literature.

People with lipoprotein(a), or Lp(a), are best treated with niacin, particularly given the relative lack of other effective therapies. I now have seen approximately 10 people with great initial responses to niacin, only to observe Lp(a) levels slowly drift back up to the starting level over a period of 2-3 years.

In other words, if starting Lp(a) is 200 nmol/l (approximately 80 mg/dl), drops to 70 nmol/l on niacin. Then, over 2-3 years of treatment, it drifts back to 200 nmol/l. Very frustrating.

Somehow, your body's Lp(a) manufacturing mechanism circumvents the niacin, sort of like antibiotic resistance (without the bacteria, of course).

My response to this, though untested, is to have people take an occasional "niacin vacation". I don't mean take a trip to the Bahamas while on niacin. I mean take 2 weeks off from niacin every three months or so. My hope is that the occasional vacation from niacin will allow the body to continue to respond and suppress "resistance". When resuming niacin, you may have to escalate the dose gradually to avoid re-provoking the "flush".

The same "resistance" seems to develop to testosterone in males: an initial drop followed by a gradual increase. Curiously, I've not seen this in females with estrogens, which seems to generate a durable Lp(a) suppressing effect. For this reason, an occasional testosterone "vacation" might also be considered.

So far, I've advised several people to try this. The long-term success or failure, however, is uncertain. I know of no other solutions, however.

If you have Lp(a) and are on long-term niacin, you should consider talking about this issue with your physician. Like many aspects of Lp(a), while fascinating in its complexity, much remains uncertain. Stay tuned.

When LDL is more than meets the eye

18. noviembre 2006 William Davis (0)
Jerry wanted to know what to do with his LDL cholesterol of 112 mg/dl. "My doctor said that it's not high but it could be better."

So I asked him what the other numbers on his lipid panel showed. He pulled out the results:

LDL cholesterol 112 mg/dl

HDL 32 mg/dl

Triglycerides 159 mg/dl


I pointed out to Jerry that, given the low HDL and high triglycerides, his calculated LDL of 112 was likely inaccurate. In fact, if measured, LDL was probably more like 140-180 mg/dl. LDL particles were also virtually guaranteed to be small, since low HDL and small LDL usually go hand-in-hand (though small LDL can still occur with a good HDL).

So Jerry's LDL is really much higher than it appears. To prove it, Jerry will require an additional test, preferably one in which LDL is measured, such as LDL particle number (NMR), apoprotein B, or "direct" LDL.

It's really quite simple. Jerry likely has a high number of LDL particles that are too small. This pattern confers a three- to six-fold increased risk for heart disease.

Treatment requires more than just reducing LDL. Small LDL--an important component of this pattern, responds, for instance, to a reduction in processed carbohydrates like wheat products (breads, breakfast cereals, pretzels, etc.), NOT to a low-fat diet. Weight loss to ideal weight, especially loss of abdominal fat, will yield huge improvements in these numbers. Niacin may be a necessary component of Jerry's treatment program, since it increases LDL size and raises HDL.

For more discussion on measures superior to LDL cholesterol, see my upcoming editorial, Let Dr. Friedewald Lie in Peace (an expansion of a previous Heart Scan Blog). It will be posted on the Cardiologist on Call column on the Track Your Plaque website within the next week.)

Oil-based vitamin D

14. noviembre 2006 William Davis (2)

As time passes, I gain greater and greater respect for the power of restoring vitamin D blood levels to normal, i.e. 50-70 ng/ml. Just yesterday, I saw several people with blood levels of <10 ng/ml--severe deficiency.

Vitamin D deficiency this severe poses long-term risk for osteoporosis, arthritis, colon cancer, prostate cancer, inflammatory diseases, diabetes, and heart disease. Vitamin D appears to make coronary plaque reversal--reduction of your heart scan score--easier and faster.

But it is important that you take the right kind of vitamin D. Several of the people I saw yesterday with vitamin D levels of somebody living in total darkness were taking vitamin D, but they were taking tablets. Tablets are the wrong form. Powder-based tablets, in my experience, yield little or no rise in blood levels. Some preparations generate a small rise but the dose required is huge.

If you're going to take vitamin D, take a preparation that yields genuine and substantial rises in blood levels. This requires an oil-based capsule. I commonly see blood levels of 25-OH-vitamin D3 rise from, say, 10 ng/dl to 60 ng/ml when oil-based capsules are taken.

The most common dose I prescribe to patients is 2000 units per day to females, 3000-4000 units per day to males in non-sun exposed months. Ideally, your dose is adjusted to blood levels.

The Vitamin Shoppe preparation pictured here is one I've used successfully and generates bona fide rises in blood levels. And it costs around $5. Just be sure the preparation you buy is oil-based.

For rapid success, try the "fast" track

14. noviembre 2006 William Davis (1)
Have you tried fasting?

Before your eyes glaze over, let me tell you what I mean. I don't mean a water-only fast for two weeks while you drool over all the temptations around you and you feel sorry for yourself.

I also don't mean the juice fasts that some people use that turn into fruit juice fasts of pure sugar.

Here's another way to do it. Usually, 48 hours of doing this will yield several benefits:

--Weight loss of 1 lb. You will likely experience an even greater weight loss of 2-4 lbs, but much of this will be water loss.

--If you're like me and share a heightened sensitivity to sugars and carbohydrates (like wheat), you may find out just how awful you feel when you eat certain foods. Many people tell me they feel absolutely wonderful when they fast--clearer thinking, increased energy, improved mood. Not the constant gnawing urge to eat they expected.

--After your fast is over, you look back and realize just what large portions of food you were eating. You'll be content with smaller quantities--and enjoy it more.


The "fast" I've used successfully includes two foods:

1) Vegetable juices--that you either juice yourself or purchase. V8 or its equivalent works pretty well. Though purchased V8 is not the best, it's better than nothing and does work reasonably well. If you juice your own vegetable juices, watch out for the diarrhea if you're unaccustomed to vegetable juices. Four 8 oz glasses per day works well.

2) Soy milk--for a source of protein and modest quantity of sugar and fat. I like the Light Silk Soymilk (Vanilla) which contains 80 calories, 2 g fat (0.5 g monounsaturated), 7 g sugar, 6 g protein per 8 oz glass. Four 8 oz glasses of soymilk also work well. In my neighborhood, 8th Continent is another good choice.


Sip both of these throughout the day. Of course, drink water in unrestricted amounts.

What can you expect in your coronary plaque control/heart scan score reversal program? When the fast is over, a rise in HDL, reduction in small LDL, reduction in triglycerides, reduction in blood sugar and insulin, and a smaller tummy. This strategy can be useful to kick-start weight loss efforts or as a periodic way to maintain control over weight and lipid/lipoprotein patterns.

No flush = No effect

13. noviembre 2006 William Davis (3)


"Inositol Hexanicotinate is the true 'flushless niacin.' Unlike 'sustained-release' niacin, which is just regular niacin in a pill which dissolves more slowly, Inositol Hexanicotinate is a niacin complex, formed with the B-vitamin-like inositol. When you take an IHN supplement, the central inositol ring gradually releases niacin molecules, one at a time delivering true niacin. This, like “sustained-release” niacin, allows you to take niacin at clinically-proven doses without going crazy with the itch."


That above bit of nonsense adorns one manufacturers sales pitch for its no-flush niacin. No-flush niacin is one of the biggest scams in the health food store.

Ordinarily, I love health food stores. There's lots of fun and interesting things available that pack real power for your health program. Unfortunately, there's also outright nonsense. No-flush niacin is absolute nonsennse.

No-flush niacin is inositol hexaniacinate, or an inositol molecule complexed with 6 niacin molecules. So it really does contain niacin. However, although it works in rats, it exerts no known effect in humans.

Just Friday, a 41-year old woman came to my office for consultation because her doctor didn't know what to do with lipoprotein(a). She had seen a cardiologist who told her to take no-flush niacin. Both the cardiologist and the patient were therefore puzzled when lipoprotein(a) showed no drop and, in fact, was slightly higher on the no-flush preparation.

The lack of any observable effect and no studies whatsoever showing a positive effect (there is one study demonstrating no effect), manufacturers continue to manufacture it and health food stores continue to push it as an alternative to niacin that causes the flush. It's quite expensive, commonly costing $30-$50 for 100 tablets.

Don't fall for this gimmick. Niacin is among the most helpful of treatments for gaining control over coronary plaque. It raises HDL, corrects small LDL, reduces triglycerides (along with its friend, fish oil, of course), reduces lipoprotein(a), and dramatically contributes to reduced heart attack risk. No-flush niacin does none of this.

"Black holes" on heart scan

Lots of smokers, especially younger smokers, rationalize their habit by telling themselves that they'll stop if and when any hint of adverse health effects develop.

The problem is that, even in the first decade of smoking, dramatic and profound effects can develop--but you won't know it.

One of the most graphic examples of this I see every day in people who have heart scans. While CT heart scans are, of course, for identification of coronary plaque/coronary disease, they're also great for visualizing the lungs.

This man is a light smoker. The lungs are the black tissues (that's normal) on either side of the (white) heart in the center. Now, note the holes in the lung tissue. That's what they literally are: holes left by the destrucive, tissue-eating effects of cigarette smoking.

How common are the holes (or emphysematous "blebs", as they're called in medical lingo)? Very common. You'll even see them in 30-somethings who've smoked only a few years.

These are holes that have nothing in them. The lung tissue that was destroyed to create the hole will never grow back, even when smoking stops. The holes in this example are actually small to average in size. I've seen much bigger. And this only represents the early stages of lung tissue destruction. A long-time heavy smoker shows all other sorts of abnormalities.

Whenever I show these "black holes" to people who smoke, they are horrified and I've actually gotten many people to quit. Take the opportunity to quit as soon as you can if you smoke.

Small LDL--a persistent bugger

10. noviembre 2006 William Davis (1)
Sometimes, small LDL is easy to get rid of. Take niacin, for instance, and it can simply disappear from your body.

But other times, it can be aggravatingly persistent. Several times every day, in fact, I need to run through the checklist of strategies to reduce small LDL with patients.

How important is small LDL? In my experience, it is among the most potent causes behind coronary plaque known. It's a big part of the explanation why some people at an LDL of cholesterol of X mg/dl will have heart disease, while others with the same X mg/dl of LDL will not. When present, small LDL particles are much more likely to trigger atherosclerotic plaque formation. Small LDL particles magnify Lp(a)'s ill-effects tremendously. The data vary but small LDL probably increases heart attack risk at least three-fold.



Here's a checklist of strategies that I advise patients to consider to minimize the small LDL pattern:


--Lose weight to ideal weight--This is very important and effective.


--Fish oil--A relatively small effect unless triglycerides are high to begin with.




--Reduction of wheat products--This can provide a BIG effect. More precisely, a reduction in high-glycemic index foods is effective. But the biggest day-to-day high-glycemic food culprits are wheat products like breads, pasta, crackers, chips, pretzels, and breakfast cereals. "You mean whole wheat bread makes small LDL?!" Yup.


--Reduction of sweets--For the same reasons as reducing wheat products.


--Add raw almonds and walnuts--1/4 to 1/2 cup per day.




--Replace wheat products with OAT products, especially oat bran. This does NOT mean oat-containing breakfast cereals with added sugar and wheat, e.g., Honey Nut Cheerios, Cracklin' Oat Bran Cereal, etc. You might as well eat candy. Buy oat bran as plain oat bran--nothing added. Use it as a hot cereal or added to yogurt, "breading" for chicken, etc.




--Vitamin D--A variable effect, likely resulting from its beneficial effects on "insulin resistance".


--Exercise


--Niacin--Very effective but not always enough.


Among the choices, my favorites are weight loss, niacin, and reduction of wheat products. Those will give you the biggest bang for your buck.

Red badge of courage

8. noviembre 2006 William Davis (0)
A group of 60- and 70-somethings were standing in the anteroom to the cardiac rehabilitation center. All (males) had their T-shirts pulled up, comparing their coronary bypass scars.

It reminds me of war veterans comparing their war wounds. The scars of suffering, of having "conquered" and won a war with a common enemy, a badge of courage.

This is part of the broad social acceptance of bypass surgery and other major procedures for heart disease. Hospitals support it. They do it for the psychological support for patients enduring a difficult process. Often, talking about a shared experience can be a helpful purge for the fears and frustrations of a traumatic event.

Curious thing, though. I've actually had people request bypass surgery simply because all their friends have had one. No kidding. "I just figure my time is coming. I might as well get it over with."

Get the picture? We've had a battle with heart disease and the hospitals have won. The enormous success of hospitals over the last 20 years is not because of delivering babies, it's not from psychiatric hospitalization, it's not from cancer treatment. It's from heart disease. The largest floors in the hospital are usually the cardiac floors. The bulk of revenues and profit are from heart disease.

If I manufacture widgets and each widget I sell makes me scads of money, guess what? I want to sell more and more widgets. I'll persuade people they need my widgets even if they don't. Perhaps I'll even persuade them that buying one is a noble cause. Maybe I'll subtly suggest that I am a charitable operation and I only sell my products for the public good. I could even name my company after a saint. Personal profit--absolutely not!

Ignore the hype. See hospitals and their "products" for what they are: A necessary service--some of the time; profitable products that they hope to sell to more and more people most of the time.

"We don't believe in heart scans"

7. noviembre 2006 William Davis (0)
Tim's CT heart scan score was an earth-shattering 3,447, clearly in the upper stratosphere of percentile rank. Risk of heart attack: 25% per year. At age 58, it was a wonder that nothing had happened yet.

Tim went to the Cleveland Clinic for an opinion, long a powerful bastion of heart procedures. The consulting cardiologist told Tim, "We don't believe in heart scans. They're wrong too often."

An opinion from a widely-respected cardiovascular center. If they don't "believe" in heart scans, does that mean they "believe" in stents and bypass surgery? Does it mean that the thousands of research studies that have now been published on the value of heart scanning are pure fiction? Is there a choice to believe or not believe?

I continue to be shocked at the extraordinary ignorance on the topic of heart scanning among my colleagues. The number one killer of Americans and you still rely on stress tests?

Why this perception that heart scans are "wrong too often"? What this cardiologist means, I believe, is that when people are taken to the cath lab for catheterization, a substantial number of those with positive heart scan scores don't have "blockage". But I could have told him that even before the heart catheterization.

There is an expected and well-documented likelihood of finding significant "blockage" based on your heart scan score. At Tim's scary score of 3,447, what is the likelihood of "blockage" of 50% or more? It's around 40-50%. That means that half the people at this score will have a blockage sufficient to justify inserting stents or undergoing bypass surgery, half will not. There will indeed be many plaques, but none severe enough to block flow.

Does that make the heart scan wrong? I don't think it does. Just because you don't need a major procedure to "fix" blockages does not mean that no heart disease is present. Without preventive efforts, Tim's heart attack risk remains an alarming 25% per year--whether or not he gets stents or bypass. The only treatments that substantially reduce this risk (in an asymptomatic person) are preventive efforts, not procedures.

Yet cardiologists like the one Tim consulted at the Cleveland Clinic regard heart scans as something "he doesn't believe in". I would suggest a return to the textbooks and published literature and re-thinking how heart disease should be managed.

Heart scans should provide an opportunity for prevention, not an opportunity for profit.

More on the “Rule of 60”

6. noviembre 2006 William Davis (0)
Despite its apparent simplicity, there’s a lot of thought and wisdom in the Rule of 60.

What if you achieve only a single value in the Track Your Plaque “Rule of 60”? What if, for instance, you got LDL down to 60 mg/dl, but ignored the fact that your HDL was 41 mg/dl and triglycerides were up to 145 mg/dl? Can you still do pretty well?

Probably not. In fact, this specific combination of low HDL and high triglycerides tells me several things:

1) LDL is really much higher than suggested by the 60 mg/dl, which is a calculated value, often much higher. Recall that calculated LDL is prone to immense inaccuracy. When measured, the LDL is commonly somewhere between 120 and 160 mg/dl. However, when you raise HDL to 60 and reduce triglycerides to 60, much of the inaccuracy is removed, i.e., calculated LDL becomes more accurate. LDL can be measured as LDL particle number (NMR), apoprotein B, or direct LDL.

2) LDL particles are small. This is yet another reason why the weight-based LDL measures can be inaccurate. Imagine you have two identical glass jars full of marbles. One jar has small marbles, the other has large marbles, but both jars have the same weight in marbles. Which jar has more marbles? The one with small marbles, of course. The same phenomenon occurs with LDL particles: at the same weight, you can have different numbers of LDL particles. It’s the number of particles that better determine risk for heart disease, not the weight.

3) Triglycerides of 145 mg/dl is actually below the target advised by the National Cholesterol Education Panel Adult Treatment Panel-III guidelines, i.e., you’re okay by conventional standard. But look beneath the surface, and you’ll find that triglycerides at 145 mg/dl are associated with flagrant excesses of VLDL lipoprotein particles and a greater likelihood of a postprandial (after-eating) disorder (increased IDL or postprandial triglycerides), both of which add to coronary plaque.

4) This pattern is also commonly associated with higher blood sugar, higher blood pressure, increased inflammation (e.g., C-reactive protein), increased fibrinogen—all the facets of the metabolic syndrome, or pre-diabetes.

In fact, some of the most aggressive plaque growth—increasing heart scan scores—will occur with this specific pattern. So just achieving one facet of the Track Your Plaque Rule of 60 does not suffice. It’s the whole package that really stacks the odds in your favor of stopping or dropping your heart scan score.

My life is easy

17. February 2007 William Davis (3)
In the old days (the 1980s and 1990s), practicing cardiology was very physically and emotionally demanding. Since procedures dominated the practice and preventive strategies were limited, heart attacks were painfully common. It wasn't unusual to have to go to the hospital for a patient having a heart attack at 3 am several times a week.

Those were the old days. Nowadays, my life is easy. Heart attacks, for the most part, are a thing of the past in the group of people who follow the Track Your Plaque principles. I can't remember the last time I had a coronary emergency for someone following the program.

But I am reminded of what life used to be like for me when I occasionally have to live up to my hospital responsibilities and/or cover the practices of my colleagues. (Though I voice my views on prevention to my colleagues, the most I get is a odd look. When a colleague recently covered my practice for a weekend while I visited family out of town, he commented to me how quiet my practice was. I responded, "That's because my patients are essentially cured." "Oh, sure they are." He laughed. No registration that he had witnessed something that was genuine and different from his experience of day-to-day catastrophe among his own patients. None.)

I recently had to provide coverage for a colleague for a week while he took his family to Florida. During the 7 days, his patients experienced 4 heart attacks. That is, 4 heart attacks among patients under the care of a cardiologist.

If you want some proof of the power of prevention, watch your results and compare them to the "control" group of people around you: neighbors, colleagues, etc. Unfortunately, the word on prevention, particularly one as powerful as Track Your Plaque, is simply not as widespread as it should be. Instead, it's drowned out in the relentless flood of hospital marketing for glitzy hospital heart programs, the "ask your doctor about" ads for drugs like Plavix, which is little better than spit in preventing heart attacks (except in stented patients), and the media's fascinating with high-tech laser, transplant, robotic surgery, etc.

Prevention? That's not news. But it sure can make the slow but sure difference between life and death, having a heart attack or never having a heart attack.

My bread contains 900 mg omega-3

15. February 2007 William Davis (8)
Phyllis is the survivor of a large heart attack (an "anterior" myocardial infarction involving the crucial front of the heart) several years ago. Excessive fatigue prompted a stress test, which showed poor blood flow in areas outside the heart attack zone. This prompted a heart catheterization, then a bypass operation one year ago.

FINALLY, Phyllis began to understand that her unhealthy lifestyle played a role in causing her heart disease. But lifestyle alone wasn't to blame. Along with being 70 lbs overweight and overindulging in unhealthy sweets every day, she also had lipoprotein(a), small LDL particles, and high triglycerides. The high triglycerides were also associated with its evil "friends," VLDL and IDL (post-prandial, or after-eating, particles).

When I met her, Phyllis' triglycerides typically ranged from 200-300 mg/dl . Fish oil was the first solution, since it is marvelously effective for reducing triglycerides, as well as VLDL and IDL. Her dose: 6000 mg of a standard 1000 mg capsule (6 capsules) to provide 1800 mg EPA + DHA, the effective omega-3 fatty acids.

But Phyllis is not terribly good at following advice. She likes to wander off and follow her own path. She noticed that the healthy bread sold at the grocery store and containing flaxseed boasted "900 mg of omega-3s per slice!". So she ate two slices of the flaxseed-containing bread per day and dropped the fish oil.

Guess what? Triglycerides promptly rebounded to 290 mg/dl, along with oodles of VLDL and IDL.

A more obvious example occurs in people with a disorder called "familial hypertriglyceridemia," or the inherited inability to clear triglycerides from the blood. These people have triglycerides of 800 mg/dl, 2000 mg/dl, or higher. Fish oil yields dramatic drops of hundreds, or even thousands of mg. Fish oil likely achieves this effect by activating the enzyme, lipoprotein lipase, that is responsible for clearing blood triglycerides. Flaxseed oil and other linolenic acid sources yield . . .nothing.

Don't get me wrong. Flaxseed is a great food. As the ground seed, it reduces LDL cholesterol, reduces blood sugar, provides fiber for colon health, and may even yield anti-cancer benefits. Flaxseed oil is a wonderful oil, rich in monounsaturates, low in saturates, and rich in linolenic acid, an oil fraction that may provides heart benefits a la Mediterranean diet.

But linolenic acid from flaxseed is not the same as EPA + DHA from fish oil. This is most graphically proven by the lack of any triglyceride-reducing effects of flaxseed preparations.

Enjoy your flaxseed oil and ground flaxseed--but don't stop your fish oil because of it. Heart disease and coronary plaque are serious business. You need serious tools to combat and control them. Fish oil is serious business for triglycerides. Flaxseed is not.

More Omnivore's Dilemma

11. February 2007 William Davis (2)
Another irresistible quote from Michael Pollan’s book, The Omnivore’s Dilemma:

“In many ways breakfast cereal is the prototypical processed food: four cents’ worth of commodity corn (or some other equally cheap grain) transformed into four dollars’ worth of processed food. What an alchemy! Yet it is performed straightforwardly enough: by taking several of the output streams issuing from a wet mill (corn meal, corn starch, corn sweetener, as well as a handful of tinier chemical fractions) and then assembling them into an attractively novel form. Further value is added in the form of color and taste, then branding and packaging. Oh yes, and vitamins and minerals, which are added to give the product a sheen of healthfulness and to replace the nutrients that are lost whenever whole foods are processed. On the strength of this alchemy the cereals group generates higher profits for General Mills than any other division. Since the raw materials in processed foods are so abundant and cheap (ADM and Cargill will gladly sell them to all comers) protecting whatever is special about the value you add to them is imperative.”

A food manufacturer’s nightmare is when you and your family shop in the produce aisle in the grocery store. Produce is unmodified (aside from the pesticide and genetic-engineering issues), not added to, and therefore of no interest to the food manufacturer, since no additional profit can be squeezed out of it. If you pay 45 cents for a cucumber, there’s no room for a processor to multiply it’s return.

Vegetables and fruits have imperfections, no doubt, particularly pesticide residues and the “dumbing-down” of some foods to increase their desirability (e.g., green grapes, what I call “grape candy”). But vegetables and fruits are the closest you can get to foods that are essentially unmodified by a food manufacturer. Due to the absence of processing, they are not calorie-dense like a bag of chips; they include all the naturally-occurring healthy factors like flavonoids that food scientists have, thus far, struggled and failed to identify, quantify, and control; and they lack all the unhealthy additives that processed foods require for extended shelf life, palatability, and reconstitution (anti-separating agents, emulsifiers, sweeteners, etc.)

Vegetables, in particular, should be the cornerstone of your plaque control program. Not breakfast cereals, breads, bacon, sausage, mayonnaise, fruit drinks and soda, all the foods that worsen the causes of coronary plaque and raise your heart scan score.

If you would like to understand how the current perverted state of affairs in food have come about, Pollan’s book is must reading.

Pollan's The Omnivore's Dilemma

11. February 2007 William Davis (0)

“ ‘You are what you eat’ is a truism hard to argue with, and yet it is, as a visit to a feedlot suggests, incomplete, for you are what what you eat eats, too. And what we are, or have become, is not just meat but number 2 corn and oil.”

Author Michael Pollan offers unique, enlightening, and entertaining insights into the food we eat in his new book, The Omnivore’s Dilemma: A natural history of four meals.

Pollan draws parallels between the dilemma of the primitive human living in the wild, having to stumble through the choices of animals and plants that could nourish or kill, and the ironically modern return of this phenomenon in present-day supermarkets. While the dangers of food choices aren’t as immediate as in the wild (eat the wrong mushroom or herb, for instance, and you die), they can nonetheless be life-threatening, or at least health-threatening. Hydrogenated oils, high-fructose corn syrup, carageenan, guar gum. . .“What is all this stuff anyway, and where in the world did it come from?”

Among the issues Pollan discusses is that of modern cattle raising practices: the rush to fatten a cow from an 80 lb calf to a 1200-pound, bloated cow over a period of 14 months. Nature created this animal to mature over a 4 to 5 year period through grazing, thus it’s beautifully “engineered” ruminant system that allows it to digest cellulose in grasses, a process that humans and other mammals are incapable of. The pressures to bring greater quantities of beef to market at a reduced price and make more money have resulted in a farming industry that encourages the incorporation of unnatural, often inhumane practices like corn feeding (rather than grass grazing), refeeding of bovine body parts (thus “mad cow disease”), and widespread and chronic administration of hormones and antibiotics.

(I can't help but think that the rapid and perverse fattening of cattle by industrial "farming" is paralleled by the fattening of the eating American. After all, we are the hapless recipients of this flood of cheap, unhealthy, plasticized food.)

The industrialization of food has de-personalized the act of eating. You no longer have any connection with the green pepper in your salad (unless you grew it yourself), nor do you have any appreciation for the suffering of the cow in your hamburger. Worse, the distortion of livestock raising practices has modified the food composition of meat. Range-fed animals, leaner and richer in omega-3 fatty acids, have been replaced by the marbled, saturated fat-rich modern grocery bought meats.

This is a theme that Pollan reiterates time and again: how food processing adds value to the manufacturer, often starting with a healthy ingredient but modifying it, adding ingredients, taking out others, until it’s something decidedly unhealthy. Yet the manufacturer will trumpet the fact that a healthy ingredient is included. Breakfast cereals are the most blatant example of this. What the heck are Cheerios but an over-processed attempt to make more money out of the simple oat?

Pollan’s eloquent and unique insights into food are definitely worth reading.

As always, per our Track Your Plaque policy, I recommend Mr. Pollan’s book strictly on its merits. We obtain no “cut”, commission, or other financial gain by recommending his book. Track Your Plaque members pay their modest membership fee for truth. They do not pay for us to advertise something that provides hidden advantage to us. We do not advertise, editorialize to steer you towards a specific product or service. What we say, we truly believe.

The most frequently asked question of all

8. February 2007 William Davis (0)
The most frequently asked question on the Track Your Plaque website:

"Can you recommend a doctor in my area who can help me follow the Track Your Plaque program?"

This is a problem. Unfortunately, I wish I could tell everyone that we have hundreds or thousands of physicians nationwide who have been thoroughly educated and adhere to the principles I believe are crucial in heart disease:

1) Identify and quantify the amount of coronary atherosclerotic plaque present. In 2007, the best technique remains CT heart scans.

2) Identify all hidden causes of plaque. This includes Lp(a), post-prandial disorders, small LDL, and vitamin D deficiency.

3) Correct all patterns.


But we don't.

You'd think that this simple formula, as straightforward and rational as it sounds, would be easily followed by many if not most physicians. But Track Your Plaque followers know that it simply is not true. My colleagues, the cardiologists, are hell-bent on implanting the next new device, providing a lot more excitement to them as well as considerably more revenue.

The primary care physician is already swamped in a sea of new information, going from osteoporosis drugs, to arthritis, to gynecologic issues, to skin rashes and flu. Heart disease prevention? Oh yeah, that too. They can only dabble in heart disease prevention a la prescription for Lipitor. That's quick and easy.

Nonetheless, I believe we should work towards identifying the occasional physician who is indeed willing to help people follow a program like Track Your Plaque. As we grow, we will need to identify some mechanism of professional education and we will maintain a record of these practitioners. But right now, we're simply already stretched to the limit just doing what we are doing.

If you come across a physician who practices in this fashion and you've had a positive relationship, we'd like to hear about it.

Do stents kill?

6. February 2007 William Davis (5)
There's apparently a lively conversation going on at the HeartHawk Blog (www.hearthawk.blogspot.com). Among the hot topics raised was just how bad it is to have a stent.

I think that my comments some time back may have started this controversy. I've lately noticed that having a stent screws up your heart scan scoring in the vicinity of the stent. I was referring to the fact that I've now seen several people in the Track Your Plaque program do everything right and then show what I call "regional reversal": unstented arteries show dramatic drops in score of 18-30%, but the artery with a stent shows significant increase in score.

This is consistent with what we observe in the world outside Track Your Plaque when stents are inserted. Someone will get a stent, for instance, in the left anterior descending artery. A year later, there will be a "new" plaque at the mouth of the stent or just beyond the far end. This is generally treated by inserting another stent. Use of a drug-coated stent seems to have no effect on this issue.

Now, my smart friends in the Track Your Plaque program would immediately ask, "Does this mean you continually end up chasing these plaques that arise as a result of stents? Do you create an endless loop of procedures?"

Thankfully, the majority of times you do not. Rarely, this does happen and can lead to need for bypass surgery to circumvent the response. But it is unusual. The tissue that grows above and below stents does seem to be unusually impervious to the preventive efforts we institute.

Perhaps there's some new supplement, medication, or other strategy that will address this curious new brand of plaque growth. Until then, you and I can only take advantage of what is known. If it's any consolation, the plaque that seems to grow because of a previously inserted stent seems to lack the plaque "rupture" capacity of "naturally-occuring" plaque. It is, indeed, somehow different. It is more benign, less likely to cause heart attack. It's always been my feeling that this tissue behaves more like the "scar" tissue that grows within stents, causing "re-stenosis", a more benign, less rupture-prone kind of tissue.

Dr. Reinhold Vieth on vitamin D

5. February 2007 William Davis (4)
A Track Your Plaque member brough the following webcast to our attention:

Prospects for Vitamin D Nutrition
which can be found at http://tinyurl.com/f93vl

Despite the painfully dull title, the webcast is the best summary of data on the health benefits on vitamin D that I've seen. The presenter is Dr. Reinhold Vieth, who is among the handful of worldwide authorities on vitamin D. In 1999, Dr. Vieth authored the first review to concisely and persuasively argue that vitamin D nutrition was woefully neglected and that its potential for health was enormous.
(See Vieth R, Am J Clin Nutr 1999 May;69(5):842-856 at http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=AbstractPlus&list_uids=10232622&query_hl=1&itool=pubmed_DocSum.)

I predict that, after viewing Dr. Vieth's hour-long discussion, you will be as convinced as I am that vitamin D is crucial for health. Unfortunately, Dr. Vieth doesn't delve into the conversation about the potential effects on heart disease, since his audience was primary interested in multiple sclerosis, a disease for which vitamin D replacement promises to have enormous possibilities. Even in 2007, the data suggesting that vitamin D has heart benefits is circumstantial. Nonetheless, from our experience, I am thoroughly convinced that, with replacement to blood levels of vitamin D to 50 ng/ml, heart scan scores drop more readily and faster.

If you view Dr. Vieth's wonderful webcast, keep in mind that when he discusses vitamin D blood levels, he's using units of nmol/l, rather than ng/ml. To convert nmol/l to ng/ml, divided by 2.5. For example, 125 nmol/l is the same as 50 ng/ml (125/2.5 = 50).

Vitamin D on Good Morning America

1. February 2007 William Davis (9)

Positive comments about vitamin D made it to a discussion on Good Morning America today about the new and exciting developments in nutrition and "functional foods".

I'm thrilled that the media is conducting these conversations. It sure is making my job easier, not having to persuade patients that taking vitamin D is truly and hugely beneficial for health. I still have to struggle with my colleagues, who tell patients to stop the "poisonous" doses we use.

But I worry that many of the details behind vitamin D don't quite make it to the media conversation. These are crucial, make-it-or-break-it issues, such as:

--Vitamin D must be vitamin D3 or cholecalciferol, not D2 or ergocalciferol. D2 is virtually worthless. Little or none is converted to the active D3, despite the fact that D2 is the form often added to some foods.

--Vitamin D3 supplements must be oil-based capsules, or gelcaps. Tablets are so poorly or erratically absorbed that it's simply not worth the effort. (We get ours from the Vitamin Shoppe.)

--The dose should be sufficient to eliminate the phenemena of deficiency, which is around 50 ng/ml. I take 6000 units per day. Dr. John Cannell of www.vitamindcouncil.com takes 5000 units per day. I give my wife 2000 units per day (she's not as deficient as I was), each of my kids 1000 units per day, except for my 180 lb. 15 year old who takes 2000 units.

I fear that, when people hear that vitamin D packs fabulous effects for health, they will take a 400 unit tablet--nothing will happen. They will not obtain the benefits such as reduction of blood pressure and blood sugar; increased bone density, reduction of arthritis, dramatic reduction in risk for fractures; reduction in risk for colon, prostate, and breast cancer; reduction in risk for multiple sclerosis; reduction in inflammatory processes such as those evidenced by C-reactive protein; and facilitation of reduction of heart scan score.

Would you bet your life on chelation?

31. January 2007 William Davis (1)

Hugh's heart scan score was 1751, an awful score. Recall that, at this level of scoring, Hugh's heart attack and death risk is 25% per year.

Obviously, serious efforts need to be taken. In this situation, much as I despise drug companies and what they represent and their heavy-handed ways, I'm more inclined to resort directly to prescription agents, as well as our nutritional supplements and other strategies. The price of dilly-dallying could be his death.

Hugh and his wife asked about chelation. Now, there are five studies I'm aware of that have tried to examine the value of chelation. None showed any measurable benefit, though all were rather weak in design and small in number of participants. One study, for instance, looked at whether anginal chest pains were provoked any later after chelation. Another looked at whether calf claudication, or calf cramping while walking due to artery blockages in the leg arteries, was delayed on treadmill testing after chelation. No benefit was observed: no delay in provocation of angina, no delay in provocation of claudication.

However, the adherents of chelation have been vehement enough that the NIH has funded a large, multi-center study to settle the question once and for all. Best I can tell, the study has not been contaminated by any drug company involvement. It is meant to be an unbiased, objective study of whether chelation has any value.

My personal experience in patients who underwent chelation is that, despite spending hundreds or thousands of dollars, plaque grew at the expected rate--no effect at all.

None of this constitutes proof of efficacy nor proof of lack of efficacy. We will need to await the NIH trial to have better information.

Should Hugh bet his life on chelation? I advised him strongly against it. At this point, the only reason I can see to pursue chelation would be faith--that is, expectation based not on fact, but on hope.

The powerful forces preserving the status quo

31. January 2007 William Davis (1)

An interesting quote from the book, Critical Condition: How health care in American became big business--and bad medicine:


Politics and Profits

To protect its interests and expand its influence, the health care industrial complex has done what all successful special interests do: It's become a big donor and a high-powered lobby in Washington. In the last fifteen years, HMOs, insurers, pharmacuetical companies, hospital corporations, physicians, and other segments of the industry contributed $479 million to political campaigns--more than the energy industry ($315 million), commercial banks ($133 million), and big tobacco ($52 million). More telling is how much the health care industry spends on lobbying. It invests more than any other industry except one, according to the nonpartiisan Center for Responsive Politics. From 1997 to 2000, the most recent year for which complete data is available, the industry spent $734 million lobbying Congress and the executive branch. Only the finance, insurance, and real estate lobby exceeded that amount in the same period, with a ttoal of $823 million. In contrast, the defense industry spent $211 million--less than one-third of the health care expenditure.


These telling statistics indicate just how vigorously profit-seeking forces in heart care are trying to preserve the status quo. Hospitals want to protect their valuable procedure-driven enterprise, the pharmaceutical industry wants to protect its enormous though little-known niche of procedure-based medications (like $1200 a dose ReoPro), and the medical device industry wants to maintain the multi-billion dollar-generating machine aided and abetted by the FDA's 501k rule (that makes entry to market a breeze).

The current procedure based formula for heart disease profits so many and they are desperate to preserve it. Resistance to the deep-pocketed efforts of industry and hospitals will come from people like you and me, trying to propagate a better way.

Remember: hospital procedures for coronary disease represent the failure of prevention. They are not--any longer--successes in and of themselves.

Read a scathing insight into some of these practices by reading investigative journalists' Donald Barlett and James Steele's book, Critical Condition. I found their descriptions painfully accurate. (But don't get too angry! Remember: only optimists reverse their plaque! We need to turn the conversation in a positive direction, not just in this Blog or the Track Your Plaque website, but nationwide.)

One of the new missions for the www.cureality.com website is to help you understand just how powerful, insidious, shrewd, and pervasive the efforts to maintain the current system truly are.
Hammers and nails

Hammers and nails

28. February 2008 William Davis (4)
I'm sure you've heard the old saying that,

To a man with a hammer, everything looks like a nail.


It couldn't be truer than in heart procedures (the man with the hammer) and heart disease (the nail).

What does it take in 2008 to become an interventional cardiologist trained in all the techniques of angioplasty, stenting, intracoronary ultrasound, etc.? Start with your undergraduate degree (4 years), then medical school (another 4 years), then training in internal medicine (3 years), then general cardiology taining (3 years), then an additional year in interventional cardiology. Each step along the way also involves competing for these spaces, a process that requires much time, money, and sweat.

The total time investment is 15 years after high school. Many if not most college students graduate with debt. Pile on the substantial cost of medical school. Training after medical school pays a modest salary, enough for a single person. Many trainees by then have spouses and a family, would like to buy a house, have bills to pay. (I managed to buy my first house for $69,000 in Columbus, Ohio and paid my mortgage by sleeping only every other night and moonlighting on my off nights.)

By the time the interventional cardiologist-in-training finishes his/her 15 years, they are hungry for a hefty increase in income. After such a time and money investment, I do believe that there is at least some justification for generous income for the years of work involved.

Back to our hammer and nail metaphor. Not only do we now have a man or woman with a hammer, but a really expensive hammer that required a substantial amount of effort to obtain. Now, our hapless hammer-bearer is desperate to see everything in sight as a nail.

You're seen in consultation by this fresh interventional cardiologist in practice for only a few years. Guess what he/she advises? Go straight to the catheterization laboratory, of course. Throw in the fact that insurance reimbursement is most generous for heart procedures, far more than for consulting in the office, doing a stress test, or other simpler, non-invasive tests, and the incentives are clear.

The system, you see, is set up to follow such a path. The path to the cath lab is heavily incentivized, paths in the other direction discouraged, disparaged, or just ignored.

My message: Don't get nailed.

    Yup.  "Hammers and nails"!

    I am 65 years old.  I had a stent inserted in the "widow-maker" artery (80% blockage) a year ago.  I had passed out a couple of times (heart rate dangerously low - 30s).  I rode to the hospital in an ambulance.  Tests revealed short LBBB episodes; mild mitral regurgitation, mild tricuspid regurgitation. Catherization showed 3 vessel CAD. I was told that a medicated stent was absolutely necessary given the situation; regardless, I have to accept that.   A pacemaker was installed to prevent bradycardia and keeps heart rate from dropping below 60.   I have 20% L distal main blockage and 90% lesion of the high first obtuse marginal at the takeoff.  The right coronary had 60% posterior lateral branch stenosis.  

    Since then I have reduced TG from 360 to 60,  LDL from 89 to 82 (although a few months ago it was in the mid-70s), and increased HDL from 30 to 46.  I went from 365lbs to 190lbs and hope to eventually get to 180lb this Spring.  I did it by progressing from walking to trotting (slow run) and dietstyle changes (low-GI veggies, fruits, etc.) .

    On a recent visit the cardiologist said the the LDL needs to be 70 or below to "freeze" the 90% blockage and gave me a prescription for Lipitor.  I asked if there were alternatives, like diet, supplements, etc.  He admitted that he did not know about those alternative but did know Lipitor.   When the only tool you have is a hammer then everything is a nail.  I understand that the 90% blockage is important but will not take the Lipitor to achieve the 12 points reduction.  Seems like an overkill.  

    I asked him if there was a way to evaluate my current condition.  I was told there was no way.  Basically, if I have no symptoms, good.  If I have symptoms then it will have to be evaluated.  Death could be the only symptom.   I swear he was about to say bypass surgery ($$$$$$!) was inevitable.  Something is wrong with this "fly-in-the-fog-and-hope-you-don't- hit-a-mountain" approach. Hope is not a strategy!

    I am confident that I can reduce LDL to below 70 based on eliminating wheat-products in my diet plus increasing oat bran in my diet.  I also take fish oil daily (EPA/DHA-2g).  I am looking for a new cardiologist.  I just recently purchased your book and find it very instructive.  In the meantime I have an appointment with my primary care physician to discuss implementing the Track Your Plaque program.  I realize that the one stent will skew the scan numbers but can be used as a baseline number.

    Anyway, onward . . .

    As an ancient engineer, I often use your aphorism.
    Your publicly expressed viewpoint must earn a lot of criticism from your colleagues, and undoubtedly there have been financial and other sacrifices on your part.
    I would like to offer heart felt appreciation for what you do.
    I assume that many colleagues share your point of view. Are there others who have the 'cojones' to speak out?  Is there any degree of cooperation?

    I would like to know something of your perspective on potential solutions for cardiology in particular, and healthcare in general. In fact, on the whole "medical-pharmaceutical-insurance-government complex" (to paraphrase the warnings of Dwight Eisenhower).
    I grew up under British socialized medicine, and while the delivery to the people is more even, it is not a  solution. Do you foresee some kind of compromise as workable? Should the solution be patient driven? Business driven? Govt. driven?
    I recall that in the UK, doctors and the system tend to be viewed as almost god like in their authority, although a few individual Dr. rebels such as. Malcolm Kendrick come to mind.

    Yes, I know. This is far too big a topic for your blog, but with the elections coming up, my curiosity just got the better of me!
    Note: I promise not to ask any more difficult questions until next Feruary 29!

    I'd like to echo the comment by Mike V.  The current health care situation in the US is so "unsustainable", to borrow an agricultural phrase, yet having a good view of the UK's NHS (I have English in-laws) doesn't inspire me to wish all of that on myself or the US public, either.  My in-laws in Norway seem to have it better in many ways, but I see some dangerous aspects creeping in over there, too.  We need better options for our nations's healthcare, but I only seem to hear about how well our current system works (for some people) with all the costly high-tech procedures and diagnostics or else warmed-over versions of the UK and Canadian systems, which has some serious flaws, too.

    I want healthcare that takes prevention and health promotion into account, not just "disease care" that catches disease "just in time".  I don't want "checkbook science" or "concensus science" dictating what options I have or what information is available to me.  I don't want a "nanny" nor do I want my care determined by healthcare industry lobbyists.  

    There must be something better, that does a better job of balancing promotion of good health with treatment of disease, with balancing good intentions without nannyism, with balancing  access to care without over treatment.  We need a system that allows medical personnel to make the best decisions for each individual patient, with a better way of managing the associated costs and compensation for all participants.   It is very hard for physicians to "buck the trends" these days.

    As an insider with an insightful view from the trenches of the healthcare industry, I'd love to read more of your thoughts on these issues in future posts, Dr. Davis (your busy schedule allowing, of course).  How can we reform healthcare without pushing the pendulum too far into another harmful direction, in a way that it beneficial to all - patients, medical personnel, medical institutions, medical research, etc?

    And then, how do we make it happen?

Risks for coronary disease 2008

31. December 2007 William Davis (27)
According to conventional thinking, there are identifiable risks for coronary disease and heart attack. These risk factors are:

* smoking
* high blood pressure
* high blood cholesterol and excessive saturated fat intake
* diabetes
* being overweight or obese
* physical inactivity

I'd agree with all the factors listed (though I would argue about the importance of high blood cholesterol and saturated fat; they are not as important as commonly made to be.)

Is the list complete?

From the unique perspectives gained in the Track Your Plaque program, I'd offer a significantly different list. Trying to stop or reduce coronary atherosclerotic plaque and heart scan scores makes you a whole lot smarter about what works and what doesn't work.

So, in addition to the risk factors listed above, I would add:

* Small LDL particles--Lots of small LDL particles is MORE important than high LDL.
* High blood pressure with exercise
* Excessive wheat intake and other processed carbohydrates--An issue of explosive importance today. Wheat creates large numbers of small LDL particles, among other adverse effects.
* Vitamin D deficiency--Among the most powerful risks I know of. It belongs at the top of the list.
* Vitamin K2 deficiency
* Low HDL cholesterol
* Blood sugar >100 mg/dl
* High triglycerides--While some argue about whether triglycerides are a risk that behaves independently of patterns like low HDL, they are neglecting the potent force of this risk. Sure, it occurs in tandem with low HDL (usually, though not always), but it is a factor that can leave you with risk even when HDL is raised to healthy levels.
* Lipoprotein(a)--It is eminently, positively crystal clear that lipoprotein(a) is a powerful risk for heart disease. The lack of a profitable treatment keeps it hidden in the shadows.
* Pessimism--Be happy, do better. Be a constantly angry, frustrated, complaining sourpuss and you are more likely to succumb to heart disease, cancer, or other undesirable fate.


These are the risk factors that we address through the Track Your Plaque program, a list that yields a far more powerful and comprehensive approach to control over coronary plaque/atherosclerosis, sufficient to achieve reversal in many (though not in all) instances.

I view the list of conventional risk factors as a "no brainer" list. Sure, smoking is a risk factor. But there are virtually no smokers in the Track Your Plaque program. If you smoke, you clearly don't care enough to engage in a high-intensity prevention program like this.

Saturated fat? Perhaps, but the battlefield of heart disease is riddled with the bodies of those who employed this as their sole strategy and failed catastrophically.

Diabetes, hypertension, and overweight all represent a continuum of risk; the solutions offered in the conventional scheme (i.e., low-fat diet, etc.) make these patterns worse, not better.

The conventional response to heart disease risk is trapped somewhere in 1973 and has not changed in over 30 years. Heart disease continues to be a growth industry for hospitals and the pharmaceutical and medical device industries. The "official" organizations continue to deliver an antiquated, outdated message.

If you want heart disease, follow the American Heart Association diet. If you want established heart disease to get worse, follow the American Heart Association diet. If you want diabetes or, if you already have diabetes or pre-diabetes, if you want it to worsen and develop organ damage (eyes, kidneys, nervous system, etc.), then follow the American Diabetes Association diet. USDA food pyramid? Loosen your belt!

The list of conventional risk factors for heart disease is woefully inadequate. If that is as far as your prevention program takes you, heart disease will not be controlled or prevented. At best, it might be slowed; at worst--and more likely--it might be accelerated.

Food sources of vitamin K2

27. December 2007 William Davis (46)


Vitamin K2 is emerging as an exciting player in the control and possible regression of coronary atherosclerotic plaque. Only about 10% of dietary vitamin K intake is in the K2 form, the other 90% being the more common K1.

The ideal source of K2 is natto, the unpalatable, gooey, slimy mass of fermented soybeans that Japanese eat and has been held responsible for substantial decreases in osteoporosis and bone fractures of aging. Natto has an ammonia-like bouquet, in addition to its phlegmy consistency that makes it virtually inedible to anyone but native Japanese.

I say that the conversation on vitamin K2 is emerging because of a number of uncertainties: What form of vitamin K2 is best (so-called MK-4 vs. MK7 vs. MK-9, all of which vary in structure and duration of action in human blood)? What dose is required for bone benefits vs. other benefits outside of bone health? Why would humans have developed a need for a nutrient that is created through fermentation with only small quantities in meats and other non-fermented foods?

Much of the developing research on vit K2 is coming from the laboratories of Drs. Vermeer, Geleijnse, and Schurgers at the University of Maastricht in the Netherlands, along with several laboratories in Japan, the champions of K2.

MK-7 and MK-8,9,10 come from bacterial fermentation, whether in natto, cheese, or in your intestinal tract; MK-4 is naturally synthesized by animals from vitamin K1. While natto is the richest source of the MK-7 form, egg yolks and fermented cheeses are the richest sources of the MK-4 form.

Chicken contains about 8 mcg MK-4 per 3 1/2 oz serving; beef contains about 1 mcg. Egg yolks contain 31 mcg MK-4 per 3 1/2 oz serving (app. 6 raw yolks). Hard cheeses contain about 5 mcg MK-4 per 3 1/2 oz serving, about 70 mcg of MK-8,9; soft cheeses contain about 30% less. Natto contains about 1000 mcg of MK-7, 84 mcg MK-8, and no MK-4 per 3 1/2 oz serving.











Feta cheese

Thanks to the research efforts of the Dutch and Japanese groups, several phenomena surrounding vitamin K2 are clear, even well-established fact:

--Vitamin K2 supplementation (via frequent natto consumption or pharmaceutical doses of K2) substantially improves bone health. While K2 by itself exerts significant bone density/strength increasing properties in dozens of studies, when combined with other bone health-promoting agents (e.g., vitamin D3, prescription drugs like Fosamax and calcitonin), an exaggerated synergy of bone health-promoting effects develop.



--The MK-4 form of vitamin K2 is short-lived, lasting only 3-4 hours in the body. The MK-7 form, in contrast, the form in natto, lasts several days. MK-7 and MK-8-10 are extremely well absorbed, virtually complete.

--Bone health benefits have been shown for both the MK-7 and MK-4 forms.

--Coumadin (warfarin) blocks all forms of vitamin K.





Interestingly, farm-raised meats and eggs do not differ from factory farm-raised foods in K2 content. (But please do not regard this as an endorsement of factory farm foods.)

Another interesting fact: Since mammals synthesize a small quantity of Vit K2 forms from vitamin K1, then eating lots of green vegetables should provide substrate for some quantity of K2 conversion. However, work by Schurgers et al have shown that K1 absorption is poor, no more than 10%, but increases significantly when vegetables are eaten in the presence of oils. (Thus arguing that oils are meant to be part of the human diet. Does your olive oil or oil-based salad dressing represent fulfillment of some subconscious biologic imperative?)

If we believe the data of the Rotterdam Heart Study, then a threshold of 32.7 micrograms of K2 from cheese yields the reduction in cardiovascular events and aortic calcification.

It's all very, very interesting. My prediction is that abnormal (pathologic) calcium deposition will prove to be a basic process that parallels atherosclerotic plaque growth, and that manipulation of phenomena that impact on calcium depostion also impact on atherosclerotic plaque growth. Vitamins D3 and K2 provide potential potent means of at least partially normalizing these processes.

As the data matures, I am going to enjoy my gouda, Emmenthaler, Gruyere, and feta cheeses, along with a few egg yolks. I'm going to be certain to include healthy oils like olive and canola with my vegetables.

Track Your Plaque: Naughty or nice?

24. December 2007 William Davis (6)


Among the many wonderful surprises we've had at Track Your Plaque this holiday season was a letter from Santa Claus himself!

It seems that Santa, like the rest of us, has been busy surfing the web for useful health information the last few months. He was struck with this curious discussion we've been having about "wheat belly" and all the unhealthy consequences of wheat products in our diet.

He writes:

"I wouldn't have believed it myself, except that my waist size has grown four inches in as many years. Sure, I'm known for my healthy girth, but now even Mrs. Claus calls me fat!

"I was open to new ideas when I came across this crazy discussion about eliminating wheat from your diet. So I said, "What have I got to lose?" Well, four weeks later and 12 lbs lighter, I'm convinced. Now comes the tough part: I've got to deliver all the toys and resist all those cookies the children put out for me. I wonder if wheat makes reindeer fat, too?

"Anyway, thanks to your program I'm back to my old weight again. Doc says my blood sugar and blood pressure are also back down to normal. Thanks, Track Your Plaque! (You'll find something extra special under the tree this year.)"

And so it goes. I'm tempted to put Santa's testimonial on our homepage, but I think that may be tooting our own horn a bit too much.

Have a wonderful holiday!

Vitamin D: Treatment for metabolic syndrome?

21. December 2007 William Davis (44)
Metabolic syndrome is that increasingly common collection of low HDL cholesterol, high triglycerides, high blood sugar, and high pressure that now afflicts nearly 1 in 4 adults, rapidly gaining ground to 1 in 3. Beyond these surface factors, metabolic syndrome also creates small LDL particles, VLDL, intermediate-density lipoproteins (IDL), increased imperceptible inflammation measured as higher c-reactive protein, and greater blood clotting tendencies. Metabolic syndrome is usually, though not always, associated with a big tummy ("beer belly," though I call it "wheat belly").

In short, metabolic syndrome creates a metabolic mess that leads to dramatic increases in heart disease, vascular disease and stroke, and cancer. The medical community has been paying increasingly greater attention to this condition because of its booming prevalence and because of the big bucks invested in "education" by the manufacturers of the diabetes and pre-diabetes drugs, particularly makers of Actos and Avandia.

But here's a curious observation:

Replacement of vitamin D to healthy levels (we aim for 50-60 ng/ml, or 125-150 nmol/l) yields:

--Higher HDL
--Lower triglycerides
--Lower blood sugar
--Reduced c-reactive protein
--Reduced blood pressure
--Reduced small LDL
--Enhanced sensitivity to insulin

(Whether blood clotting and effects on IDL should be added to this list is uncertain.)

It's obvious: Vitamin D is proving to be a very important and powerful corrective influence on many of the facets of the metabolic syndrome. In fact, I would go as far as saying that, side by side, vitamin D yields nearly the same effect as prescription drugs Actos and Avandia--without the extravagant cost (nearly $200 per month), leg swelling, congestive heart failure and heightened heart attack risk (with Avandia), and average 8 lb weight gain. Of course, vitamin D also provides benefits beyond metabolic syndrome like facilitation of coronary plaque regression, increased bone density, reduced arthritis, and reduced risk of several cancers.

You'd think that agencies like the American Diabetes Association (ADA) would be all over vitamin D like white on rice. Yet they remain curiously quiet about the entire issue. (That should come as no surprise to anyone familiar with the behavior and politics of this organization, the same outfit that has widely propagated the ADA diet, a program that accelerates diabetes and its complications. In my view, the ADA is an embarassment.)



For a really great story and video on vitamin D that includes a terrific interview with vitamin D guru and Track Your Plaque friend, California psychiatrist Dr. John Cannell, go to What's the Real Story on Vitamin D?. While the video will yield little new to readers of The Heart Scan Blog or Track Your Plaque members, it just feels really good to see a well-made, high-class video production echoing many of the things we've been talking about these past two years.

Appetite stimulants

20. December 2007 William Davis (17)
Ever have days when you just can't seem to get enough to eat, your stomach gnawing just a hour after a meal? We all get them, some more than others. Other days, you can be content with a few simple foods and hunger is subdued, temptation easy to control.

Why such contrasts on different days?

A major part of the reason can be the presence of appetite stimulants, factors that trigger appetite beyond rational control. The list of common appetite stimulants includes:

--Sleep deprivation--A very important factor. Lack of sleep drives tremendous appetite, and often for the wrong foods (processed carbohydrates). I personally have experienced my most shamefully indulgent days when sleep-deprived. The solution is obvious: Sleep. Another factor that is based purely on personal observation is that of waking mid-phase. In other words, waking up while you're still enjoying the deeper phases of sleep (e.g., phase 3,4, or REM). This can oddly disrupt your day and your impulse control. I usually try and time sleep to increments of 90 minutes to coincide with the average duration of the full cycle of sleep. For example, 7 1/2 hours is better than 8 hours, since the extra half hour puts your square into a deeper sleep cycle.

--Excessive caffeine--Caffeine stimulates stomach acid. This triggers the impulse to eat . . . and eat and eat.













Image courtesy Wikipedia

--Aspirin and other anti-inflammatory agents--If you take aspirin (as many of our Track Your Plaquers do), then beware of the gastritis that can develop. Like excessive caffeine, it also triggers the impulse to eat, likely a protective mechanism, since food sops up excess acid. I ask patients to take periodic breaks from aspirin, e.g., a week off every two or three months, to allow the stomach to heal. Alternatively, an occasional dose of acid-suppressing medication is a safe practice, e.g., Pepcid AC 10-20 mg; Prilosec 10-20 mg.

--Wheat-containing foods--Followers of The Heart Scan Blog know my feelings on this. Wheat is a potent appetite stimulant: Eat something containing wheat like a pretzel or whole wheat bagel, and you want more. You may want more immediately, or a little later when your blood sugar plunges after the wheat-driven insulin surge. Solution: Dump the wheat, one of the most unhealthy food groups around.

--Alcohol--Though perhaps not a direct appetite-stimulating effect, the loss of impulse-control with alcoholic drinks can lead to overindulgence, often in the worst foods. Just beware.

--Hanging around with heavy people. Remember peer pressure? It can be subliminal. People with poor eating habits provide the silent message that it's okay to yield to impulse, overeat, overindulge, and choose the wrong foods.

--Stress--Whether through cortisol stimulation or other means, stress triggers appetite in some people. If you experience this and must give in, reach for raw nuts or nuts, rather than wheat snacks or chips. The effect will be minimal, perhaps even beneficial, rather than the bloating, appetite-stimulating, fattening effect of crackers, chips, or pretzels. This may be the same phenomenon as taking prescription steroids like prednisone.

--Short dark days, long nights--In other words, winter. Though just an anecdotal observation, I am convinced that vitamin D supplementation is an effective antidote to this effect. The short, dark days just don't bother you as much, perhaps not at all, and there's no impulse for comfort foods.


How about appetite suppressants? In this list I would include 1) raw nuts--especially almonds, walnuts, pecans, and pistachios, the sort with a fibrous covering and rich in monounsaturates, 2) other sources of plentiful healthy oils, e.g, use more olive oil in your salad or add it to hummus for your veggie dip, 3) space-occupying fibers such as glucomannan, inulin (such as in Fiber Choice), and psyllium seed products. Counteracting the above appetite stimulants like sleep deprivation is, of course, important.

The coming wheat frenzy, otherwise known as the holidays, is an especially important time to be aware of these effects. Eat, drink, and be merry--but with rational impulse control not driven by subconscious appetite stimulants.

"Heart scans are experimental"

18. December 2007 William Davis (25)
Let me warn you: This is a rant.

It is prompted by a 44-year old woman. She has a very serious lipoprotein disorder. Her family experiences heart attacks in their 40s and 50s. I asked for a heart scan. Her insurance companied denied it.

This is nothing new: heart scans, like mammograms, have not enjoyed reimbursement from most insurers despite the wealth of data and growing acceptance of this "mammogram" of the heart.

However, 10 minutes on the phone, and the "physician" (what well-meaning physician can do this kind of work for an insurance company is beyond me) advised me that, while CT heart scans for coronary calcium scoring are not covered, CT coronary angiograms are.

Now, I've been witnessing this trend ever since the big players in CT got involved in the game, namely Philips, Siemens, Toshiba, and GE. These are enormous companies with hundreds of billions of dollars in combined annual revenues. They, along with the lobbying power of cardiology organizations like the American College of Cardiology, have gotten behind CT coronary angiograms. This is most likely the explanation of why CT coronary angiograms have rather handily obtaining insurance reimbursement. Interestingly, the insurance company I was speaking to is known (notorious?) for very poor reimbursement practices.

A CT heart scan, when properly used, generates little revenue, a few hundred dollars to a scan center, barely enough to pay for a device that costs up to $2 million. However, CT coronary angiograms, in contrast, yield around $2000 per test. More importantly, they yield downstream revenues, since CT angiograms are performed as preludes to conventional heart catheterizations, angioplasty, stents, bypass surgery, etc. Now we're talking tens or hundreds of thousands of dollars revenue per test.

What puzzles me is that much of that increased cost comes out of the insurance company. Why would they support such tests if it exposes them to more costs? I'm not certain. It could be the greater pressures exerted by the big CT companies and powerful physician organizations. I seriously doubt that the insurance companies truly believe that heart scans for coronary calcium scoring are "experimental" while CT coronary angiograms are "proven." If all we did was compare the number of clinical studies that validate both tests, we'd find that the number of studies validating heart scans eclipses that of coronary angiograms several fold. Experimental? Hardly.

The smell of money by physicians eager to jump on the bandwagon of a new revenue-producing procedure is probably enough to have them lobby insurers successfully. In contrast, plain old heart scans just never garnered the kind of vigorous and vocal support, since nobody gets rich off of them.

If CT coronary angiograms are sufficiently revenue producing that my colleagues and the CT scanner manufacturers have managed to successfully lobby the health insurers, even one as financially "tight" as the one I spoke to today, well then I take that as testimony that money drives testing, as it does the behavior of hospitals, many of my colleagues, and can even force the hand of insurers.

When meat is not just meat

18. December 2007 William Davis (7)

The edgy nutrition advocate, Mike Adams, over at NewsTarget.com came up with this scary photo tour of a processed meat product from Oscar Mayer: Mystery Meat Macrophotography: A NewsTarget PhotoTour by Mike Adams







Along with increasingly close-up photographs of this meat-product, Adams lists the ingredients in Oscar Mayer's Cotto Salami:


Beef hearts
Pork
Water
Corn syrup
Beef

Contains less than 2% of:
Salt
Sodium lactate
Flavor
Sodium phosphates
Sodium diacetate
Sodium erythorbate
Dextrose
Sodium nitrite
Soy lecithin
Potassium phosphate
Potassium chloride
Sugar


As I reconsider the role of saturated fat in diet, given the startlingly insightful discussion by Gary Taubes of Good Calories, Bad Calories, I am reminded that not all meat is meat, not all saturated fat sources are equal.

I am concerned in particular about sodium nitrite content, a color-fixer added to cured meats that caused a stir in the 1970s when data suggesting a carcinogenic effect surfaced. The public's effort to remove sodium nitrite from the food supply was vigorously opposed by the meat council and it remains in cured meats like sausage, hot dogs, and processed meats like Cotto Salami. A 2006 meta-analysis (combined analysis of studies) of 63 studies did indeed suggest that sodium nitrite was related to increased risk of gastric cancer. This argument is plausible from animal models of cancer risk, as 40 animal models have likewise suggested the same carcinogenic association.

Also, fructose? This is most likely added for sweetness. Recall that fructose heightens appetite and raises triglycerides substantially.

I personally have a natural aversion to meat. I don't like the taste, the look, smell, and the thought of what the animal went through to make it to the supermarket. But, considered from the cold, carnivorous viewpoint of the question, "Is meat okay to eat?", among the issues to consider is whether the meat has been cured or processed, and does that process include addition of sodium nitrite.

Cotto Salami and similar products are not, of course, what carnivorous humans in the wild ate. This is a processed, modified product created from factory farm animals raised in cramped conditions and fed corn and other cheap, available foods. It is not created from free-ranging animals wandering their pastures or pens, eating diets nature intended. This results in modified fat composition, not to mention hormones and antibiotics added. These are not listed on the ingredients. Wild meat does not contain fructose or color-fixers, either.

So don't mistake "meat" in your grocery store for meat. It might look and smell the same--until you look a little closer.

Don't lament no OTC mevacor

17. December 2007 William Davis (4)
After Merck's third go at FDA approval for over-the-counter (OTC) status for its statin cholesterol drug, Mevacor (lovastatin), the FDA advisory board suggested that its request be denied. They expressed concern that too many people would not understand how the drugs would be used and that misuse would be common.

Similar sentiments were echoed by Dr. Sidney Wolfe, director of the Health Research Group at Public Citizen; the American Medical Association (though the AMA always fights anything that threatens to erode physician control over health); and the de facto spokesman for cardiologists, Dr. Steven Nissen of the Cleveland Clinic.

Although I am a supporter for tools and legislation that yield greater self-empowerment in health care to the public, there is no need to lament the failed OTC status for Mevacor. For one, Merck had no plans to reduce the price on its OTC preparation. For many people, this would have meant an increase in cost, since health insurers would surely not cover a non-prescription agent.

Second, OTC status sends the implicit message that cholesterol is the most common cause of heart disease; it is not. (Small LDL particles are the number one cause, a pattern only partially addressed by any statin drug and a pattern largely responsible for the failure of statin drugs to "cure" heart disease despite pharmaceutical manufacturer's attempts to increase doses to take up any slack in effect.)

Thirdly, you can achieve the same effect--no, a superior effect--by incorporating several simple strategies into your life. These strategies are superior to Mevacor because they do more than just reduce LDL cholesterol. You can achieve similar LDL-reducing effect to Mevacor, 20 mg, just by adding:

--2 tablespoons oat bran or ground flaxseed per day (choose flaxseed if you have sugar problems or small LDL; flaxseed contains no digestible sugars, only protein and fiber)
--Raw almonds or walnuts--at least a handful, though more is fine and will not make you fat. (It's nuts like party mixes, mixed nuts roasted in unhealthy oils, and honey-roasted nuts that make us fat, not raw.)
--Soy protein sources--probably the weakest effect of all foods listed, but a contributor that can be obtained in a variety of forms, such as tofu, soy protein powders, and soy milk.
--Other foods that reduce LDL include pectin sources (e.g., citrus rind), flavonoids (e.g., green tea); stanol esters found in butter substitute Benecol (recall that sterol-containing products like Take Control and the flood of new products on the market like HeartWise orange juice might have potential for allowing sterol esters to enter the blood, so I do NOT recommend them); and, of course, niacin.

Many of these strategies also reduce small LDL, raise HDL, reduce triglycerides, and reduce blood sugar, effects that go beyond that achieved with Mevacor. Of course, a combination strategy is not as easy as popping one pill a day, it's better for you.

I will certainly not shed any tears for Merck and its relentless efforts to gain a stronger foothold in the "transform conditions into diseases" marketing strategy, the same strategy that classifies shyness, toe fungus, and sadness into medical conditions necessitating medication. While I do generally support efforts to increase public access to strategies that increase their health care power, this one was not necessarily all good.

Damage control

15. December 2007 William Davis (5)
Medical device manufacturer, Cordis, is launching a new marketing program to promote its Cypher drug-coated stent. You can view the details at www.CypherUSA.com , including the slick TV commercial that HeartHawk posted a blog about.

The campaign opens with:

When you open up your heart, you open up your life.

Lives hampered by angina. By shortness of breath. By restricted blood flow. These lives are changing. Because of a state-of-the-art advancement. One that can have a huge impact on arteries around your heart. The CYPHER® Stent. It can open up your arteries. Increase flow of blood and oxygen. And change your restricted life. To an active life worth living. Your new life is...

Life Wide Open


Direct-to-consumer drug advertising has been around for a few years. While it has increased awareness of drugs and the "conditions" they are supposed to treat, it has also highlighted the aggressive profit-motive of the drug industry. This is not health care for the needy and sick, but health care for profit.

So now we're beginning to see the emergence of direct-to-consumer (DTC) advertising for medical devices. There was also a brief, though unsuccessful, foray into DTC advertising for implantable defibrillators, of all things, by Medtronic a couple of years ago, also.

What is the purpose of Cordis' marketing effort? Is it to educate and inform the public who might unknowingly receive non-drug coated stents and be deprived of the restenosis-inhibiting advantage of a drug-coated device? Is it meant to right a systematic wrong, a failure of cardiologists to insert the technologically, biologically, and ethically superior coated stents?

I find that doubtful. A more likely motive is damage control. With some of the (both deserved and undeserved) negative press the drug-coated stents have received lately, Cordis, eager to protect their $20 billion (annual revenues, 2006) medical device franchise, came up with this DTC strategy. After viewing the smiling faces of people , elated because of their "wide open" arteries and lives, Cordis hopes to see people going to their doctors insisting on the stent that is "opening millions of lives," since, "when your arteries narrow, so does your life."

Cool, trendy, liberating. That's the message they wish to deliver. Cool music, beautiful people, flashy high-tech images. Who wouldn't want a Cypher stent?

Beyond damage control, it's a familiar marketing theme: You're slender, glamorous, and sexy if you drink Coke, you're a caring mother if you feed your children Jif peanut butter, you're health conscious and smart if you eat Total cereal . . . you're cool and know what you want from life if you insist on a Cypher stent.

I don't object to advertising. It's part of the capitalistic economic system. It drives awareness and grows businesses. I do get concerned when advertising is so slick and effective that the people who are not properly armed with information can be duped into thinking that they need something that they don't really need.

Or, for which there are powerful, viable alternatives. Even hear about "prevent the disease in the first place?"

Low expectations

12. December 2007 William Davis (6)
The Framingham Risk Calculator is a standard method used by many physicians to predict risk for heart attack or death from heart disease over a 10-year period. Low-risk is defined as <10% risk of heart attack or cardiac death over 10 years; high-risk is defined as 20% or more over 10 years; intermediate-risk is in between.

Let's put it to the test:

Amy is a 53-year old businesswoman. She is 5 ft 4 inches, weighs 150 lbs. Her father had a heart attack in his early 50s followed by the usual list of hospital procedures including bypass surgery at age 60.

What is Amy's risk for heart attack or death from heart disease over the next 10 years? If we enter her data into the Framingham risk calculator, the following result is returned:

Information about your risk score:
Age: 53
Gender: female
Total Cholesterol: 198 mg/dL
HDL Cholesterol: 74 mg/dL
Smoker: No
Systolic Blood Pressure: 120 mm/Hg
On medication for HBP: No
Risk Score: 1% Means 1 of 100 people with this level of risk will have a heart attack in the next 10 years.


So, according to the Framingham calculation, Amy has <1% risk for heart attack or death from heart disease over the next 10 years. Most primary care physicians would, at most, prescribe a statin drug and talk about a reduction in saturated fat.

Thankfully, Amy didn't fall for that bit of conventional mis-information. She instead got a CT heart scan, principally because of her father's history. Her score: 117. At age 53, this put her into 90th percentile, in the worst 10% of scores for women in her age group (50-55). By heart scan criteria, her risk for heart attack is probably more like 4-5% per year, or approximately 40-50% over the next 10 years.

Let's do just a bit more math. If Amy hadn't known about her heart scan score and no preventive action was taken, the expected progression of her heart scan scores would likely be:

Start: 117
Year 1: 152
Year 2: 198
Year 3: 257
Year 4: 335
Year 5: 436
Year 6: 567
Year 7: 737
Year 8: 958
Year 9: 1245
Year 10: 1618

In fact, given Amy's starting heart scan score of 117, it is highly unlikely that she survives the next 10 years without heart attack or a fatal heart event. Yet the Framingham risk calculator puts Amy's risk at less than 1%. Could anything be more wrong?

The folly of the Framingham calculator was highlighted by a recent publication from the large Multi-Ethnic Study of Atherosclerosis (MESA), in which 3600 women (45-84 years), all of whom fell into the "low-risk" category by the Framingham calculator--just like Amy--were tracked over approximately 3 3/4 years. This study generated several observations:

1) 30% of the "low-risk" women had positive heart scan scores.
2) 5% of the "low-risk" women had scores of 300 or greater (very significant for a woman). 8.6% of these women experienced a cardiovascular event like heart attack or death over the period. Women with a heart scan score of 300 or greater had a 22-fold greater event risk compared to women with zero heart scan scores.
3) Women with heart scan scores of 1 to 299 had a cardiovascular event risk of approximately 5-fold greater risk over the period.


Across the U.S., 90% of women younger than 70 years old fall into the Framingham "low-risk" category. Yet this fiction is accepted as the prevailing standard, along with LDL and total cholesterol, for determination of risk in women and men.

In my view, using the Framingham risk calculator is a misguided, misleading path, one that will mis-classify a substantial number of women who could otherwise be spared from heart attack and catastrophe.

By the way, Amy is also the Track Your Plaque program record holder (by percentage drop), with a 63% drop in heart scan score over a 15 month period.
