Stents, defibrillators, and other profit-making opportunities

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?

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?

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

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

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?

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

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

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

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!

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.

"I gained 30 lbs from one cracker"


Let me tell you a story, a tale of a woman who gained 30 lbs by eating one cracker.

At age 50, Claire's health was a disaster. Her initial lipoprotein patterns were a mess, including HDL 36 mg/dl, triglycerides 297 mg/dl, blood sugar 122 mg/dl (pre-diabetic range), blood pressure 155/99. Small LDL comprised over 90% of all LDL particles.

At 5 feet 3 inches, she weighed 210 lbs--90 lbs over her ideal weight. Her face was flushed and red, her eyes swollen and weighted down with bags, her eyes dull. While interested in hearing about how to improve her health, I would hardly call her enthusiastic.

We talked about how removing wheat products entirely from her diet could result in weight loss--enormous weight loss--yet with reduced appetite, increased energy, less daytime sleepiness and fogginess, improved sleep quality. Removing wheat would also allow substantial correction of her lipoprotein patterns with minimal medication.

At first, she seemed confused by this advice. After all, it ran directly opposite to what she'd been told by her family doctor, not to mention the advice from TV, food ads, and food packages.

To my surprise, Claire did it. She didn't return to the office for another 5 months. But she came in, a big beaming smile on her face.

Even at 167 lbs--still overweight--Claire looked great. She glowed. She'd already dropped nearly 2 1/2 inches from her waist. She felt lighter on her feet, discovered energy she thought she'd lost 10 years earlier. Her blood results matched, with dramatic shifts in each and every pattern.

I quizzed Claire on her diet, and she had indeed made substantial changes. In addition to eliminating all foods made of wheat flour, she also eliminated foods made with cornstarch, rice flour, snacks, and other sweets. She ate her fill of vegetables, fruits, raw nuts, lean meats, and healthy oils. She was less hungry while eating less. Even her husband, skeptical at first, joined Claire after the first two months and her initial 20 lbs of weight loss. He, too, was well on his way to dropping to ideal weight.

But a dinner party invitation came. In the few that Claire and her husband had gone to over the few months, she had religiously stuck to her program, choosing cheese, pickles, olives, vegetables that she dipped, but avoided the pretzels, breads, Doritos, potato chips, and others.

This time, a tray of whole wheat crackers was laid on the buffet table, covered with some sort of sweetened cheese. She had just one. She savored the taste that she'd missed. "Maybe one more. I'll be extra good this weekend,'" she told herself.

Now Claire was hungry. The bruschetta covered with tomatoes and mozzarella looked awfully good. "It's got some good things on it, too!" she thought. She had three.

The floodgates opened. I saw Claire three months later, weighing just shy of 200 lbs. "I almost cancelled this appointment," she whispered quietly, tears at the corner of her eyes. "I don't know what happened. I just lost control. After losing all that weight and feeling so good, I blew it!"

I've seen it before: Fabulous success eliminating the foods that created the situation--the insatiable appetite, the endless cycle of hunger, brief satiety, the rolling, rumbling hunger--followed by temptation, then disaster. The weight lost comes right back.

It's experiences like Claire's that have absolutely, positively convinced me: Wheat products are addictive. It's not true for everybody, but it's true for many people, certainly most people who have weight struggles. It triggers some sort of appetite button, a signal to eat more . . . and more, and more. Keep it up long enough, and you have drops in HDL, increases in triglycerides, upward jumps in blood sugar and blood pressure, diabetes, etc. It doesn't matter if it's whole grain, 7-grain, or 12-grain. Yes, the whole grains contain more fiber and more B vitamins. But they all share one characteristic: They trigger a desire for more.

So that's the story of how one whole wheat cracker caused one woman to gain 30 lbs.


Next week's story:

California woman claims: My children are aliens!


Just kidding.

Wheat-free is not gluten-free

Eliminate wheat from your diet and wonderful things happen:

--Lose 15-20 lbs, sometimes in the first 1-3 months. (More or less, depending on your prior dietary habits, weight, age, etc.)
--HDL cholesterol goes up, triglycerides go down
--Blood sugar drops
--Small LDL is reduced
--C-reactive protein is reduced
--Pre-diabetics often convert to non-diabetics
--Diabetics gain far better control over blood glucose. Some even become non-diabetic (as long as they maintain the wheat-free, low-glycemic index diet and weight control).
--You feel better: Less mental fogginess, more energy, better sleep.
--Appetite shrinks dramatically.


(Many diet programs makes lots of money promising similar results. Prescription medications like the pre-diabetes drugs, Actos and Avandia, and the fibrates, Tricor and Lopid, nearly--nearly--reproduce the effects of eliminating wheat. Of course, these medications do not lead to weight loss or make you feel better. In fact, Actos and Avandia usually trigger a weight gain of 8 lbs in the first year of use.)


All of these wonderful effects develop with elimination of wheat. . . unless you confuse wheat-free with gluten-free. There's a difference.

Remove wheat from your diet, but discover the world of gluten-free products made for people with celiac disease, or gluten enteropathy, and you can regain the weight and recreate many of the phenomena associated with wheat. I've talked about this in past, but it trips up so many people that it's worth talking about again.

The concept that I am advocating is really low-glycemic index (or low glycemic load, actually). Foods that trigger a substantial rise in blood sugar, whether immediate (like whole wheat crackers) or delayed (like whole wheat pasta) are the culprits. The same effects develop with candy, cookies, fruit drinks, pizza, chips, table sugar, and other junk foods.

However, I pick on wheat specifically because it so dominates the American diet. It has grown to fill so many processed food products. It is also a food ingredient that is falsely advertised as healthy. In reality, pretzels, whole wheat crackers, whole grain bread, high-fiber cereals, etc. exert the same effect on blood sugar as candy or white table sugar. They also generate all the "downstream" phenomena listed above.

But wheat is hardly the only food that makes us fat, diabetic, and unhealthy. This is true for foods made with cornstarch (taco shells, cornbread, tortillas, chips, breakfast cereals); rice flour, puffed rice, and polished rice; and potatoes, particularly pulverized potato starch (potato chips). There are others.

These are the gluten-free products that are marketed to the gluten enteropathy (celiac disease) market. Yes, you can make muffins with cornstarch and no wheat gluten, but is it good for you?

No. It is nearly as bad as wheat. It can still skyrocket blood sugar, drop HDL, raise triglycerides, create small LDL, heighten inflammation, etc.

Ground flaxseed, oat bran, barley, quinoa, are some of the alternatives that do not create these effects. But not the majority of gluten-free products on the market.




Ingredients: Potato starch, rice flour, modified corn starch, olive oil, yeast, vegetable protein(lupine), corn syrup, sugar, salt, hydroxypropyl methylcellulose, sodium bicarbonate, ammonium bicarbonate, diacetyltataric acid esters of mono- and diglycerides of edible fats, natural flavor.

". . . only naturally gluten-free and wheat-free ingredients and adhere to the strictest quality processes, testing every batch for gluten using the ELISA assay."

Death to chelation?


Does chelation work?

It's a question I get asked fairly frequently. Although I have never performed chelation, IV or oral, and therefore have no direct experience, my concerns for this purported therapy have included:

1) The concept of extracting calcium from atherosclerotic plaque by removing it first from the blood is absurd. Early chelationists believed that this was the means by which EDTA might reverse coronary atherosclerosis. However, removing calcium from blood would more likely lead to osteoporosis or calcium extraction from bone, since bone is a more ready repository for calcium. Blood calcium levels are also tightly and narrowly controlled; any significant reduction in calcium ("hypocalcemia") can be life-threatening. And, indeed, there have been deaths from hypocalcemia in people receiving chelation.

More recently, chelationists have argued that removal of heavy metals like lead and mercury are responsible for the purported benefits of chelation. And, indeed, blood levels of these heavy metals can be reduced by chelation. That alone may be a benefit. But to then make the leap to say that it also regresses atherosclerotic plaque by the same mechanism has no basis in science.

2) Practitioners associated with chelation tend to be shady. I have seen homeopathic therapies (among THE most ridiculous of concepts), "energy balance" therapies, desiccated organ extracts ("applied kinesiology"), and a variety of other fringe treatments offered by practitioners offering chelation. This doesn't necessarily mean, of course, that chelation is also fringe or suspect, but it tends to be offered by practitioners who engage in generally unscientific, unfounded practices.


The few people I've seen go through multiple courses of chelation (usually 30 or so infusions) have shown no impact on heart scan scores or any other measure of heart disease.

In response to the many questions I receive on chelation, I had been answering that, if we would simply wait for the publication of the NIH-sponsored trial of IV chelation therapy, perhaps we'd know once and for all.

However, in a lengthy criticism, four expert authors argue that the TACT trial to assess chelation study is doomed to failure for an entire list of reasons and should therefore be abandoned. The discussion is available on Medscape Cardiology. (Free sign-in required.)



Why the NIH Trial to Assess Chelation Therapy (TACT) Should Be Abandoned
We investigated the social and the scientific histories of chelation therapy beginning in the 1950s. We examined TACT protocols and consent forms, which, in response to Freedom of Information Act (FOIA) requests, the NIH provided to us with curious redactions. We examined the existing RCTs and the numerous case series cited by the TACT protocols. We examined evidence for risks, including information that is not in the standard medical literature. We examined various hypotheses that advocates have offered to explain how chelation "works."

We present our findings in 4 parts. First, we provide a brief history of the use of disodium EDTA as a treatment for CAD. Next, we describe the origin and nature of the TACT. Next, we discuss the evidence for chelation as a treatment for CAD and for atherosclerosis in general, and place it in the context of other proposed treatments that have been ineffective after an initial period of enthusiasm. Finally, we discuss the risks. For each topic, we contrast our findings with relevant statements in the TACT literature, to the extent that such statements exist.



Among the highlights:

--Since the mid-1970s, court documents and newspapers have reported at least 30 deaths associated with IV disodium EDTA, most of it administered by ACAM members.

--Early chelation investigators had chosen the disodium salt of EDTA, reasoning that if it could remove calcium from atherosclerotic plaques, it might shrink them. That notion was soon demonstrated to be invalid. It has largely been replaced by a "toxic heavy metals" antioxidant hypothesis, which is based on the potential for metal ions to produce free radical damage. Chelationists now cite "removing heavy metals" as the basis for their claim that chelation is effective for approximately 70 conditions, ranging from schizophrenia and autism to cancer. This provides them with numerous reasons to ignore any trial that finds chelation ineffective for CAD.

--Biochemical literature, either not cited or misrepresented in the TACT protocols, has demonstrated that the heavy metals hypothesis is implausible. Antithetically, it also demonstrates that the chelation mixture used in the TACT has pro-oxidant effects in vitro.

--In our opinion, TACT literature -- including 2 versions of the protocol, the consent form, information posted on the NCCAM Web site, and 2 editorials co-authored by the PI -- has misrepresented chelation, its risks, and the facts of the study. It has exaggerated the value of supportive case series, not only by ignoring evidence of bias and incompetence, but by misrepresenting citations and reporting erroneous data. It has minimized the dangers, both by understatements and by omissions of specific, published complications. It has not acknowledged the deaths mentioned above. It has repeatedly conflated disodium EDTA and a different drug, calcium-sodium EDTA.

--The TACT includes nearly 100 "chelation site" co-investigators who, in our opinion, are unsuitable to care for human subjects or to report trial data. Most espouse implausible health claims while denigrating proven methods; several have been disciplined, for substandard practices, by state medical boards; several have been involved in insurance fraud; at least 3 are convicted felons. Several were members of the ACAM or GLACM IRBs mentioned above. Few appear to have real expertise, required by TACT literature, in treating patients with CAD or in conducting clinical trials. Most continue to promote chelation while the TACT is in progress, contrary to good science, to human studies ethics, and to US Federal Code.


While the criticism itself does not prove the point one way or another, as a clinical trial should, anyone contemplating chelation therapy would be well-advised to read the document first. Another reference: EDTA chelation therapy for cardiovascular disease: a systematic review.

American Diabetes Association


These are actual quotes from the American Diabetes Association website:


Myth #2 (from list of Diabetes Myths): People with diabetes can't eat sweets or chocolate.
If eaten as part of a healthy meal plan, or combined with exercise, sweets and desserts can be eaten by people with diabetes. They are no more “off limits” to people with diabetes, than they are to people without diabetes.



Myth #5: If you have diabetes, you should only eat small amounts of starchy foods, such as bread, potatoes and pasta.
Starchy foods are part of a healthy meal plan. What is important is the portion size. Whole grain breads, cereals, pasta, rice and starchy vegetables like potatoes, yams, peas and corn can be included in your meals and snacks. The key is portions. For most people with diabetes, having 3-4 servings of carbohydrate-containing foods is about right. Whole grain starchy foods are also a good source of fiber, which helps keep your gut healthy.





How can I have sweets and still keep my blood glucose on target?
The key to keeping your blood glucose on target is to substitute small portions of sweets for other carb-containing foods in your meals and snacks. Carb-containing foods include bread, tortillas, rice, crackers, cereal, fruit, juice, milk, yogurt, potatoes, corn, and peas. For many people, having about 45 to 60 grams at meals is about right. Serving sizes make a difference. To include sweets in your meal, you can cut back on the other carb foods at the same meal.

For example, you’d like to have cookies with your lunch. Your lunch is a turkey sandwich with two slices of bread. Your first step is to identify the carb foods in your meal. Bread is a carb. You decide to swap two slices of bread for two slices of low-calorie bread and have the cookies -- it’s an even trade. Your total amount of carbohydrate remains the same for the meal.



Can I eat foods with sugar in them?
For almost every person with diabetes, the answer is yes! Eating a piece of cake made with sugar will raise your blood glucose level. So will eating corn on the cob, a tomato sandwich, or lima beans. The truth is that sugar has gotten a bad reputation. People with diabetes can and do eat sugar. In your body, it becomes glucose, but so do the other foods mentioned above. With sugary foods, the rule is moderation. Eat too much, and 1) you'll send your blood glucose level up higher than you expected; 2) you'll fill up but without the nutrients that come with vegetables and grains; and 3) you'll gain weight. So, don't pass up a slice of birthday cake. Instead, eat a little less bread or potato, and replace it with the cake. Taking a brisk walk to burn some calories is also always helpful.


Or take a look at the recipes for breads, muffins, cakes, pies, cookies, and pizza.


My point? As I often say, while the "official" organizations like the American Diabetes Association, the American heart Association, and the USDA dominate the message provided to mainstream Americans, to those of us who know better, they have become irrelevant. You can see how obviously boneheaded their advice is. I'd go so far as to say that, if you want diabetes, follow the American Diabetes Association diet. If you have diabetes, and you'd like to accelerate complications like kidney disease, heart disease, and neuropathy, then follow the American Diabetes Association diet.

I'm going to bet that American Diabetes Association sponsors like Lilly, Novo Nordisk, Merck, Pfizer, Abbott ($1 million or more annual contributions) and Cadbury Schweppes (3-year, multi-million dollar support for Weight Loss Matters program) will continue to charge full-speed ahead to maintain the status quo. Cadbury Schweppes are the proud makers of Dr. Pepper, Hawaiian Punch, Snapple, Motts' Apple Juice, and Hires Root Beer--you know, the foods and drinks that you can have as long as you adjust your insulin dose or talk to your doctor about adjusting your diabetes medications. And if you gain, say, 30 or 40 lbs eating these foods. . . well, we've got a treatment for that. Merck's Januvia , for instance, can help you out for only about $200 a month!

Looking at the facts this way, and it seems like some cheap conspiracy theory: They're all out to get us. Dispense information that virtually guarantees propagation of the disease, and all your friends and cronies profit. I don't know if it is or it isn't, but it sure smells like it sometimes.

A tan does not equal vitamin D

The sun is getting stronger and the days are getting longer, even here in Wisconsin.

Some people are coming to the office with nice tans obtained by sunning themselves for several hours. Others have come back from winter getaways to Florida, Arizona, or the tropics, also sporting nice, dark tans.

Several people, in fact, were so confident that sunning themselves provided sufficient vitamin D that they reduced their usual dose. Some even stopped their vitamin D altogether.

But, when blood levels of 25(OH) vitamin D were checked, they were virtually all low, sometimes as low as <20 ng/ml. Yet all had nice tans.

Why does this happen? Why would people with dark tans remain deficient in vitamin D?

One big factor is age: Anyone over 40 years old is fooling themselves if they think that a tan ensures raising vitamin D levels to a desirable range. Also, the more you tan, the more melanin skin pigment accumulates, and the more vitamin D activation in the skin is blocked.

Weight is another factor: Heavier people need more vitamin D, sometimes three- or four-fold more than slender people.

Why does aging result in inefficient skin activation of vitamin D? It seems that, once we are beyond our reproductively useful years, this ticking clock of aging gets triggered. The older we get, the less activation of vitamin D occurs in our skin, the less of the youth-maintaining, disease-preventing benefits of vitamin D we obtain with sun exposure.

The message: Don't rely on a tan to gauge the adequacy of vitamin D. Maybe that works when you're 16 years old, but not at age 50 or 60. There's only one way to know your vitamin D status: a blood level of 25(OH) vitamin D.

Planned obsolence

In the 1960s, you’d purchase a new car. If you changed the oil, adhered to the maintenance schedule—and were lucky—you might expect to get 100,000 miles out of your automobile. Only an occasional car made it beyond that odometer hurdle. Even if the engine made it past the 100,000 mile milestone, the automobile body would inevitably start to develop rusting decay at the edges of the fenders, signaling body rot that threatened to open gaping holes of metal.



Then along came Toyota and Honda, whose cars easily reached 100,000 miles and well beyond, reliably and with bodies intact. As this realization sunk into the American consciousness, many asked, “Why can’t American automakers accomplish the same sort of trouble-free longevity?” “Buy American” emerged as a mantra to preserve American jobs and prop up an economy vulnerable to the superior automotive products from Detroit’s competitors.

Of course, American automakers have since responded to the challenge posed by the Japanese auto industry and produced automobiles that essentially matched the reliability and longevity of Japanese cars. But, the great unanswered question remains: For years before the onslaught of Japanese competition, did Detroit quietly plot to maintain a policy of planned obsolescence that ensured Americans would have to scrap the old and buy a new car every few years whenever the odometer tipped over 100,000 miles?

We will never know. At worst, it may represent the behind-closed-doors, back-slapping sort of plotting that, for many years, maximized revenues, ensured shareholder returns, and secured executive paychecks. Or, perhaps it wasn’t some evil conspiracy but just complacency, a profitable position of comfort at that. There’s little incentive for industry insiders to reveal such self-incriminating information.

But the example set by the American auto industry presents an unusual learning opportunity for us, a chance to make some useful comparisons to the heart healthcare industry.

Is the American healthcare industry also guilty of practicing a policy of “planned obsolescence,” just like Detroit? The product that helplessly crumbles is, of course, not your rust-riddled automobile, but you.

When someone sees a primary care physician year after year, yet appears one morning in the emergency room, clutching his or her chest in agony from the closed coronary artery responsible for a life-threatening heart attack—prompting the flurry of activity that results in $100,000 in hospital procedures . . .

Perhaps “planned obsolescence” is not the perfect phrase to describe the situation, but the principle still applies: A failure to inform the patient that such an outcome was possible—no, probable—makes you wonder whether such an outcome was predictable and thereby preventable in the first place.

What should we do when planned obsolescence leads us down a path engineered by someone who has something, often substantial, to gain? Even if it's just complacency, or adhering to a beaten, ineffective status quo (can you say "low-fat diet?), it all points in the same direction.

You have a choice: Refuse to buy a 1962 Impala of health care, otherwise known as conventional heart disease management.

Melatonin for high blood pressure?

Melatonin is fascinating stuff.

In addition to its use as a sleep aid, melatonin exerts possible effects on cardiovascular parameters, including anti-oxidative action on LDL, reduction in sympathetic (adrenaline-driven) tone, and reduction in blood pressure.

Several studies document the blood pressure-reducing effect of melatonin:

Daily nighttime melatonin reduces blood pressure in male patients with essential hypertension.

Melatonin reduces night blood pressure in patients with nocturnal hypertension.

Prolonged melatonin administration decreases nocturnal blood pressure in women.

Blood pressure-lowering effect of melatonin in type 1 diabetes.


But blood pressure may be increased when melatonin is added to nifedipine, a calcium channel blocker:

Cardiovascular effects of melatonin in hypertensive patients well controlled by nifedipine: a 24-hour study.


Effects on BP tend to be modest, on the order of 5-8 mmHg reduction in systolic, half that in diastolic.

But don't pooh-pooh such small reductions, however, as small reductions exert mani-fold larger reductions in cardiovascular events like heart attack and stroke. NIH-sponsored NHANES data (see JNC VII), for example, document a doubling of risk for each increment of BP of 20/10. The Camelot Study demonstrated a reduction in cardiovascular events from 23% in placebo subjects to 16.7% in subjects taking amlodipine (Norvasc) with a 5 mm reduction in systolic pressure, 2 mmHg drop in diastolic pressure. Small changes, big benefits.

Many people take melatonin at bedtime and are disappointed with the effects. However, a much better way is to take melatonin several hours before bedtime, e.g., take at 7 pm to fall asleep at 10 pm. Don't think of melatonin as a sleeping pill; think of it as a sleep hormone, something that simply prepares your body for sleep by slowing heart rate, reducing body temperature, and reducing blood pressure. (You may need to modify the interval between taking melatonin and sleep, since individual responsiveness varies quite a bit.)

I also favor the sustained-release preparations, e.g., 5 mg sustained-release. Immediate-release, while it exerts a more rapid onset of sleep, allows you to wake up prematurely, The sustained-release preparations last longer and allow longer sleep.

The dose varies with age, with 1 mg effective in people younger than 40 years, higher doses of 3, 5, even 10 or 12 mg in older people. Sustained-release preparations also should be taken in slightly higher doses.

The only side-effect I've seen with melatonin is vivid, colorful dreams. Perhaps that's a plus!

The forces that shape heatlh care

Thinking about the programs for health care reform proposed by the three Presidential candidates highlights a distinct peculiarity of American style health care.

American health care is shaped to an unprecedented degree by five forces:

1) The drug industry

2) The health insurance industry

3) Hospitals

4) Fear of litigation

5) The uniquely American attitude of refusing compromise in access to health care services or products, regardless of the cost (for those who can afford health insurance)


All five of these unique forces have created this thing (monster?) we call health care. Remove or modify any one of these forces, and the health care landscape would look dramatically different.

The drug industry has recently been on the receiving end of plenty of negative press. This warms my bones. Decades of heavy-handed lobbying, sleazy marketing to physicians (all too willing to be wined and dined), and behind-the-scenes manipulation of clinical data are coming back to bite them. Sadly, the drug industry is so powerful that this bit of fuss is not likely to substantially change their ways.

I am thrilled that all three Presidential candidates agree that reimportation of drugs from outside the U.S. is a good idea. While the shrug of the shoulders federal and state attitude towards importation of drugs from Canada has not resulted in cost savings sufficient to impact on overall costs, it surely will lead to savings when practiced on a broad basis by pharmacies, distributors, and other bulk buyers of pharmaceuticals.

Senator Obama, in particular, has used strong language in his criticism of the health insurance industry, tough talk that is needed in an age in which insurance executives bring home salaries in the hundreds of millions of dollars and stock prices are climbing due to substantial profit gains within the industry, going against the grain of increasingly costly premiums. However, the Clinton experiment of federalizing health care during Bill Clinton's term that caused all the big boys to band together (most notably health insurance companies and drug industry) has tempered enthusiasm for attacking the insurance industry head-on. In both Democrats' health care reform proposals, the option of private insurance is preserved, as it is in the McCain proposal.

How about hospitals? Hospitals, though on a smaller scale than the nationwide reach of the drug and insurance industries, aim to maintain health service delivery in hospitals. For instance, the high-tech bypass service in the hospital gets plenty of local media coverage, as does the newest DaVinci robotic surgery, bariatric surgery, and other revenue-rich services. Many hospitals have forgotten that their mission is delivery of health, of which revenue creation and profiting from disease should only be part.

How big is fear of litigation? Estimates vary, but several have quoted numbers in the neighborhood of 20 to 30% of overall health care costs. At the street level from what I see, I'd say at least that much. Fear of litigation is rampant, often unrestrained, and sometimes leads to the craziest, illogical sequence of testing. Chest pain, for instance, no matter how trivial, will typically trigger around $5000 worth of testing (nuclear stress test, echocardiogram, laboratory work, etc.) Emergency room visit for a minor injury? CT scan of head, chest, abdomen. A formula to minimize this aspect of fear in health care delivery would generate enormous savings.

The last issue, the uncompromising nature of Americans in health--always wanting the latest new drug, new procedure, "best" surgeon--often simply causes the health care consumer to fall victim to marketing. If a hospital advertises the newest procedure, people want it regardless of whether it represents genuine improvement over the older procedure. The newest sleeping pill, antidepressant, antihypertensive, etc. replaces the old yet equivalent product, but at considerably greater cost.

I am optimistic that, regardless of which candidate gains the White House, that some reform is on the way. I do fear, however, that progress will be small and incremental, since major change of the sort that would slash hundreds of billions of dollars in costs would rouse the powers-that-be (drug industry, health insurers, etc.) to once again combine forces and combat the disruption of their franchise.

Until you and I see real change and cost savings coming through either legislation or free market advances, we need to continue to make full use of the self-empowering health information that we gain through venues like the web.

Lipoprotein(a): Surprising Poll Results

No doubt, our little informal poll asking readers whether they have lipoprotein(a), is skewed towards people inclined to respond because they have this genetic trait.

Nonetheless, the response is telling. Of 82 respondents:

--40 (48%) said they did have Lp(a)

--16 (19%) said that they did not have Lp(a)

--26 (31%) said that they did not know whether or not they had Lp(a)


Though admittedly an informal analysis, I'd draw several conclusions from this simple "experiment".

One, while the proportion of people responding that they have Lp(a) may not be accurate, it is a prevalent genetic risk factor that, according to formal studies, is present in 17% of people with coronary or vascular disease, 11% of the broader population. This number may be even higher if the newer particle number assays (measurements) are used (with results expressed in nmol/L), since an occasional person with a "normal" Lp(a) in mg/dl (weight-based) will prove to have increased Lp(a) by nmol/L (particle number-based). (The reason for this phenomenon is not clear. It may be consequent to variation in apo(a) size, with larger apo(a) varieties of Lp(a) occasionally escaping detection .) As our little poll shows, plenty of people have Lp(a).

Two, readers of this blog tend to be highly motivated, sophisticated, and knowledgeable about health and heart disease. Yet a substantial portion--31%--did not know whether they have this crucial risk factor. That shouldn't be. The unnecessary difficulty of getting this simple blood test performed has been driven home to me repeatedly when I identify this factor in someone and then suggest that their grown children and parents, each of whom have a 50% chance of having Lp(a), be tested. It's not uncommon for a 35-year old son, for instance, to say that his doctor refused, claiming it is an unproven risk marker, or to simply say that he/she doesn't know what it is.

No doubt, just knowing whether you have Lp(a) or not is not the end of the story. Reducing Lp(a) and its associated co-factors is no easy matter. With several hundred patients in my practice with Lp(a), it occupies much of my time and energy. Sometimes it leads to enormous successes , but it can also pose a real challenge.

There should no longer be any doubt that Lp(a) is associated with significantly increased risk of cardiovascular disease. This has been demonstrated conclusively across dozens of studies. Risk from Lp(a) is over and above that posed by other risk factors; it also amplifies the risk posed by other factors, e.g., small LDL, inflammatory phenemena, homocysteine, total LDL, low HDL.

In the world of Lp(a), our two most desperate needs for the future are:

1) Better education of physicians and the public, and

2) More effective treatment options.

Thus, our reasons to form The Lipoprotein(a) Research Foundation. Steps to gain tax-exempt status are being pursued as we speak.

I can't help but wonder whether, like vitamin D, a solution is right beneath our noses. An investment in research to fund the trials to better explore both basic science as well as practical treatment options might yield an answer more readily than we think. Wouldn't that be great?
