What Mr. Clinton did NOT do

12. February 2010 William Davis (36)

You've likely already heard that former President Bill Clinton underwent a heart catheterization today during which one of the bypass grafts to his coronary arteries was found to be occluded. The original coronary artery was therefore stented.

Dr. Alan Schwartz, Mr. Clinton's cardiologist, announced to the gathered press that Mr. Clinton had followed a good diet, had adopted a regular exercise program, but that his condition is a "chronic disease" like hypertension that is not cured by these efforts.

Needing a stent just 6 years after four bypass grafts are inserted is awfully soon. I would propose that it has less to do with having a "chronic disease" and more to do with all the things that Mr. Clinton likely is NOT doing. (In addition to all the other things that Mr. Clinton did not do.) In other words, in the Track Your Plaque world, procedures are a rarity, heart attacks virtually unheard of. I would wager that Mr. Clinton has been doing none of the following:

--Taking fish oil. Or, if his doctor was "advanced" enough to have advised him to take fish oil, not taking enough.
--Vitamin D--Followers of the Heart Scan Blog already know that vitamin D is the most incredible health find of the last 50 years, including its effects on reducing heart disease risk. Unless Mr. Clinton runs naked in a tropical sun, he is vitamin D deficient. A typical dose for a man his size is 8000 units per day (gelcap only!).
--Eating a true heart healthy diet. I'll bet Mr. Clinton's doctor, trying to do the "right" thing, follows the prudent course of advising a "balanced diet" that is low in fat--you know, the diet that causes heart disease. Judging by Mr. Clinton's body shape (central body fat), it is a virtual certainty that he conceals a severe small LDL pattern, the sort that is worsened by grains, improved with their elimination.
--Making sure that hidden causes are addressed--In addition to the "hidden" small LDL, lipoprotein(a) is another biggie. Lp(a) tends to be the province of people with greater than average intelligence. I believe Mr. Clinton qualifies in this regard. I would not be at all surprised if Mr. Clinton conceals a substantial lipoprotein(a) pattern, worsened in the presence of small LDL.
--Controlling after-meal blood sugars--Postprandial (after-eating) blood sugars are a major trigger for atherosclerotic plaque growth. There are easy-to-follow methods to blunt the after-meal rise of blood sugar. (This will be the subject of an in-depth upcoming Track Your Plaque Special Report.)
--Thyroid normalization--It might be as simple as taking iodine; it might involve a little more effort, such as supplemental T3. Regardless, thyroid normalization is an easy means to substantially reduce coronary risk and slow or stop coronary plaque growth.

It's not that tough to take a few steps to avoid bypass surgery in the first place. Or, if you've already had a procedure, a few additional steps (of the sort your doctor will likely not tell you about) and you can make your first bypass your only bypass.

Magnesium and arrhythmia

11. February 2010 William Davis (35)

Because magnesium is removed during municipal water treatment and is absent from most bottled water, deficiency of this crucial mineral is a growing problem.

Magnesium deficiency can manifest itself in a wide variety of ways, from muscle cramps (usually calves, toes, and fingers), erratic blood sugars, higher blood pressure, to heart rhythm problems. The abnormal heart rhythms that can arise due to magnesium deficiency include premature atrial contractions, premature ventricular contractions, multifocal atrial tachycardia, atrial fibrillation, and even ventricular tachycardia, fibrillation, and Torsade de Pointes (all potentially fatal). Magnesium is important!

Magnesium supplementation is therefore necessary for just about everybody to maintain normal tissue levels. (The exception is people with kidney disorders, who should not take magnesium without supervision, since they retain magnesium.)

Here is a Heart Scan Blog reader's dramatic rhythm-correcting response to magnesium supplementation:

Dr. Davis,

A few months ago, I contacted you inquiring if you had written any articles on arrhythmia. You were generous enough to answer and guide me to an LEF article you'd written in which you stressed fish oil and magnesium. I had been suffering with bad PVCs [premature ventricular contractions] for over 20 years, and they had gotten so bad recently that I was told my next options were ablation or pacemaker!

I was already on fish oil and had not seen any difference, and so I researched the magnesium you suggested more thoroughly and found a huge body of studies supportng its effect on arrhythmia. I also read many posts on heart forums with people having success with it. After getting advice from various bloggers, I tried magnesium taurate in the morning and Natural Calm (an ionized form of mag citrate) in the afternoon and evening. Within three days the PVCs were quite diminished and by 2 weeks totally gone! As long as I keep taking it, they never return---not even one irregular blip---even when I drink strong coffee! The magnesium also cleared up my restless leg syndrome, my eye twitching, and insomnia. (Apparently, I was the poster-girl for magnesium deficiency.)

I am so angry that after all these years of suffering, trying various medications, and seeing at least 4 different cardiologists that NOT ONE ever even mentioned trying magnesium. The generosity of the few minutes you took to answer my email and steer me in a helpful direction brought me total relief.

Thank you SO MUCH!

Warmly,
Catherine C.

Thinner by Thursday

10. February 2010 William Davis (0)

You want to lose a few pounds . . . Okay, maybe 50 or 75.

Should you exercise? Lengthen you workout? Push the plate away, deny yourself seconds, use a smaller plate?

Of all the weight loss strategies I've tried in patients, there's only one that stands out as a means of obtaining immediate--meaning within 3 days--weight reduction.

Wheat elimination.

Omega-3 Index: 10% or greater?

9. February 2010 William Davis (19)

We've previously considered the question:

What is an ideal level of omega-3 fatty acids in the blood?

Recall that omega-3 levels in red blood cells (RBCs), a measure called the "omega-3 index," have been associated with risk for sudden cardiac death:

In a recent analysis, 265 people experiencing sudden death during a heart attack (ventricular fibrillation, successfully resuscitated) showed an omega-3 index of 4.88%, while 185 people not experiencing sudden death during a heart attack showed an omega-3 index of 6.08%.

We have more ambitious goals than just avoiding sudden death, of course! How about the omega-3 index associated with reduced risk for heart attack? A recent analysis of females from the Harvard School of Public Health suggested that RBC omega-3 levels as high as 8.99% were still associated with non-fatal heart attack (myocardial infarction), compared to 9.36% in those without heart attacks, suggesting that even higher levels are necessary to prevent non-fatal events.

Most recently, another study comparing 50 people after heart attack with 50 controls showed that people with heart attack had an omega-3 index of 9.57% vs 11.81% in controls--even higher. (This study was in a Korean population with higher fish consumption. There was also a powerful contribution to risk from trans fat RBC levels.) The investigators concluded: "The area under the receiver operating characteristic curve of fatty acid profiles was larger than that for traditional risk factors, suggesting that fatty acid profiles make a higher contribution to the discrimination of MI cases from controls compared with modified Framingham risk factors."

The data suggest that, while an omega-3 index of 7.3% is associated with reduced risk for sudden cardiac death, a higher level of 10% or greater is associated with less risk for heart attack. Surprisingly, fish consumption and fish oil intake account for only 47% of the variation in omega-3 index.

I believe the emerging data are becoming increasingly clear: If you desire maximal control over heart health, know your omega-3 index and keep it 10% or higher.

Let's soak 'em with fish oil

8. February 2010 William Davis (12)

If you don't think that charging drug prices for fish oil is wrong, take a look at a letter from an angry Heart Scan Blog reader:

Hello Dr. Davis,

My 44 year old brother had an MI [myocardial infarction, or heart attack] in June. He got pushed around due to "bad government insurance," a state-run program for the "uninsured": government pays 1/3, job pays 1/3, and individual pays 1/3.

What they didn't tell him is that there is no major medical coverage and little to no prescription coverage. We fought for 4 months to get him open heart surgery that the insurance was not going to pay for.

Now, with no assistance, terrible insurance, and no disability he has little to no income. He is a heavy equipment mechanic and is trying to be the "good American"-- take care of his bills, not file bankruptcy, etc.

Anyway, the doctors never seem to pay attention to what they prescribe. Lipitor was not working for him, due to side effects. Now they want to give him Zetia and Lovaza....Zetia at $114, and Lovoza is $169.85! Wow! For dead fish???? I think this is a little fishy! I looked up Lovaza, gee how nice, they will give you a $20 coupon....

Forget it, he can't afford this stuff. So I am enrolling in the Zetia program for him. And trying to get him OTC [over-the-counter] fish oil. The most prevalent fish oil around here (that I take myself is) Omega 3 Fish Oil that has EPA 410mg, DHA 274.

Thanks for your blog. It made me feel better that I wasn't the only one outraged by this stuff. I 've been a nurse for 20 years and it just never seems to get better. Thank you for your wisdom.

Sincerely JP, Tennessee

Had this reader not been aware that her brother could take fish oil as a nutritional supplement, he likely would have been denied the benefit of omega-3 fatty acids in slashing the risk for recurrent cardiovascular events. You and I can buy wonderfully safe and effective fish oil as a nutritional supplement, but there won't be a sexy drug representative to sell it, nor an expensive dinner and payment for a trip to Orlando to hear about it.

Heart scan gone wrong

6. February 2010 William Davis (9)

Those of you reading the Heart Scan Blog, I hope, have come to appreciate the power in measuring atherosclerotic plaque, the stuff of coronary artery disease, and not relying on indirect potential "risk factors," especially the fictitious LDL cholesterol.

However, like all things, even a great thing like heart scans can be misused. Here's a story of how a heart scan should NOT be used, submitted by a reader.

Dr. Davis,

First of all, let me start out by commending you on all of the work you are doing with your website, blogs, etc. You are truly a breath of fresh air at a time when conventional medicine is no longer making any sense. In the last 3 years or so, I have spent a lot of time using the internet to try and find answers . . . and just about every time, when I find things that make "sense," it coincides which the recommendations you provide. Thank You!!

I am 56 years old, and roughly 5 years ago I bought your book, Track Your Plaque, primarily because I had asked my then Internal Medicine physician about why we weren't more "proactive" about determining the state of our cardiovascular health...since the means to do so existed (scans). He was trying to get me to go on a statin because my cholesterol #'s were a little high and at the time I smoked. Other than that, I was in perfectly good health with no side effects or issues. The following year at my annual physical, we again discussed this and he gave me a few options and I ended up having a calcium score done, which showed some blockage, but again, I never had any pains, sweats, or any other symptoms whatsoever, and I am a very active former athlete. This is when I bought your book to try and set a course of plan that wouldn't just include pharmaceuticals.

At the same time, my father was in his last months of life dealing with prostate cancer and the multiple radiation and chemo treatments, so I was making many trips from my home to be with him . . . a 4 hour drive, and very disruptive to family, as I still have 3 kids at home. At what I thought was going to be my last visit with him, I stopped at the cemetery he had planned on being buried to confirm details and such and then started home.

As I was driving, a symptom hit me which I was unfamiliar with (pretty sure it was an anxiety attack now) and I stopped at a friend's house in Chicago, as I didn't want this to be a heart attack while I was driving. This is when I began thinking about the heart scan and the blockage, and ended up driving back later that night and went right to the ER....not because I had any chest pains, but thought it best to be checked out because I did not want to go before my dad did. I ended up staying the night. In the morning the cardiologist PA [physician's assistant] came in with a copy of my calcium scoring and said it was best to have a heart cath...which I was in total agreement with since it would definitively tell me the current condition of my coronary vessels. As I was getting ready to be wheeled into the cath lab, they approached me with a form that would allow them to treat (stent). This is where I became very uncomfortable, in that I had never even met the cardiologist . . . and I didn't like this. No one ever had asked if I was experiencing pains or anything else . . . but I buckled and signed the form.

Before you knew it, I was awake watching my heart being cathed and the cardiologist angry because they did not have all the right sizes of stents, so he had to use a couple extra and I ended up w/5 total . . . and my life changed forever! In looking back, I can't necessarily argue the need for intervention, but in hindsight, it would have been nice to have tried an alternative method of reversing my plaque, especially since I had never experienced any symptoms and didn't appear to be in any imminent danger.

Upon release from the hospital I was put on a cocktail of drugs that typically follow and I then began to search and research. No one talked to me about lifestyle changes other that smoking....but nothing on diet or other means of cholesterol control, etc....in fact, when I had to pick out my meals in the hospital, they wouldn't let me have cheese....but the rice crispy treat was fine....how stupid! They originally told me the Plavix had to last 6 months....and then 12....and then 2 years....I stayed on it for 1-1/2 years and it was the only thing other than a baby aspirin. I went to another cardiologist out of town and he wanted me back on 5 or 6 medications and said that now I had the stents....I would have to be on these for life.....and he was the expert that talked at several main conferences.....my last trip to him.

Now, fast forward to about 6 months ago: I was participating in a father-son soccer scrimmage and was playing goalie. It was wet out and I couldn't catch very well. So being the competitive person I am, I resorted to using my chest on several of the saves and also took a direct blow to my eye ( I wear glasses) and the eye started swelling up pretty good. We then finished and went inside to have pizza and everyone was concerned about my eye. About 30 minutes later I excused myself as i felt some pretty significant sweats and subsequently a pretty severe pain directly in the middle of my chest....I was having a heart attack! Called 911 and went to hospital (2-1/2 years since original stents) and my local cardiologist removed the blockage that was at the anterior portion of my 1st stent causing the blockage. The huge disappointment to me is that I had taken many steps to improve my overall health. But now that I have foreign bodies in my vessels, the chance of further clotting is something that i will most likely always have to live with.

BU, Michigan

This is an example of how heart scans should NOT be used. They should NEVER be used to justify a procedure, no matter how high the score or where the plaque is located. The "need" for procedures is determined by symptoms (BU's symptoms were hardly representative of heart disease), blood findings, EKG, stress testing, and perhaps CT coronary angiography. "Need" for procedures can never be justified simply on the basis of the presence of plaque by a heart scan calcium score.

Unnecessary procedures like the one BU underwent are not entirely benign, as his experience at the soccer game demonstrated.

Heart scans are truly helpful things. But, like many good things, they are subject to misuse in the hands of the uncaring or greedy.

Blood sugar: Fasting vs. postprandial

5. February 2010 William Davis (23)

Peter's fasting blood glucose: 89 mg/dl--perfect.

After one whole wheat bagel, apple, black coffee: 157 mg/dl--diabetic-range.

How common is this: Normal fasting blood sugar with diabetic range postprandial (after-eating) blood sugar?

It is shockingly common.

The endocrinologists have known this for some years, since a number of studies using oral glucose tolerance testing (OGTT) have demonstrated that fasting glucose is not a good method of screening people for diabetes or pre-diabetes, nor does it predict the magnitude of postprandial glucose. (In an OGTT, you usually drink 75 grams of glucose as a cola drink, followed by blood sugar checks. The conventional cut off for "impaired glucose tolerance" is 140-200 mg/dl; diabetes is 200 mg/dl or greater.) People with glucose levels during OGTT as high as 200 mg/dl may have normal fasting values below 100 mg/dl.

High postprandial glucose values are a coronary risk factor. While conventional guidelines say that a postprandial glucose (i.e., during OGTT) of 140 mg/dl or greater is a concern, coronary risk starts well below this. Risk is increased approximately 50% at 126 mg/dl. Risk may begin with postprandial glucoses as low as 100 mg/dl.

For this reason, postprandial (not OGTT) glucose checks are becoming an integral part of the Track Your Plaque program. We encourage postprandial blood glucose checks, followed by efforts to reduce postprandial glucose if they are high. More on this in future.

Diabetes from fruit

2. February 2010 William Davis (38)

Mitch sat in my office, looking much the same as he had on prior visits.

At 5 ft 7 inches, he weighed a comfortable 159 lb, though he did have a small visible "paunch" above his beltline.

I had been seeing Mitch for his heart scan score of 1157 caused by low HDL of 38 mg/dl, severe small LDL (87% of total LDL), and lipoprotein (a).

Part of Mitch's therapeutic program was elimination of wheat, cornstarch, and sugars, the three most flagrant triggers of small LDL particles, and weighing his diet in favor of oils and fats to reduce Lp(a). However, Mitch somehow failed to follow our restriction on fruit, which we limit to no more than two 4 oz servings per day, preferably berries. He thought we said "Eat all the fruit you want." And so he did.

Mitch had a banana, orange, and blueberries for breakfast. For lunch, along with some tuna or soup, he'd typically have half a melon, a pear, and red grapes. For snacks, he'd have an apple or nectarine. After dinner, it wasn't unusual for Mitch to have another piece of fruit for dessert.

Up until Mitch's last visit, he'd had blood glucose levels of 100-112 mg/dl, above normal and reflecting mild insulin resistance and pre-diabetes. Today, on his unlimited fruit diet, his blood sugar: 166 mg/dl--well into diabetes territory.

I helped Mitch understand the principles of our diet better and advised him to reduce his fruit intake to no more than the 2 small servings per day, as well as sticking to our "no wheat, no cornstarch, no sugar" principles.

While fruit is certainly better than, say, a half-cup of gummy bears (84.06 g carbohydrates, 50.12 g sugars), fruit is unavoidably high in carbohydrates and sugars.

Take a look at the carbohydrate content of some common fruits:

Apple, 1 medium (2-3/4" dia)
19.06 g carbohydrate (14.34 g sugar)

Banana, 1 medium (7" to 7-7/8" long)
26.95 g carbohydrate (14.43 g sugar)

Grapes, 1 cup
27.33 g carbohydrate (23.37 g sugar)

Pear, 1 medium
25.66 g carbohydrate (16.27 g sugar)

Source: USDA Food and Nutrient Database

Fruit has many healthy components, of course, such as fiber, flavonoids, and vitamin C. But it also comes with plenty of sugar. This is especially true of modern fruit, the sort that has been cultivated, hybridized, fertilized, gassed, etc. for size and sugar content.

When you hear such conventional advice like "eat plenty of fruits and vegetables," you should hear instead: "eat plenty of vegetables. Eat a small quantity of fruit."

The sniff test

31. January 2010 William Davis (0)

It is well established that omega-3 fatty acids from fish oil are free of mercury, PCBs, furans, and other pesticide residues. Several independent analyses have all agreed: little to none are contained in fish oil. In the Consumer Lab series of assessments, for example, no fish oil supplement failed because of any heavy metal or pesticide residue.

However, oxidative byproducts are a problem. Just as fish that sits on the store shelf or your refrigerator too long starts to smell "fishy," so will fish oil. When fish or fish oil becomes rancid, smelling like rotten fish at its worst, it means that

Thumb your nose at swine flu

29. April 2009 William Davis (35)

Judging from what we know about vitamin D, it is highly probable that it confers substantial protection from viral infections, including swine flu.

Dr. John Cannell of the Vitamin D Council (www.vitamindcouncil.com) first connected the dots, identifying the possibility of an influence of vitamin D on incidence of flu.

In 2006, Dr. Cannell reports noticing that the patients in his psychiatric ward in northern California were completely spared from the influenza epidemic of that year, while plenty of patients in adjacent wards were coming down with flu. Dr. Cannell proposed that the apparent immunity to flu in his patients may have been due to the modest dose of 2000 units vitamin D per day he had prescribed that the patients in other wards had not been given. (Since the hospital was run by the state of California, Dr. Cannell apparently had only so much leeway with vitamin D dosing.) While it’s not proof, it’s nonetheless a fascinating and compelling observation.

A similar conclusion was reached in a recent analysis of the National Health and Nutrition Examination Survey demonstrating that the higher the vitamin D blood level, the less likely respiratory infections were.

Personally, I used to suffer through 2 or 3 episodes of a runny nose, sore throat, hacking cough, fevers and feeling crumby every winter. Over the last 3 years since I’ve supplemented vitamin D, I haven’t been sick even once. The past two years I didn’t bother with the flu vaccine, since I suspected that my immunity had been heightened: no flu either winter.

And so it has been with the majority of my patients. Since I began having patients supplement vitamin D to achieve normal blood levels (we aim for 60-70 ng/ml), viral and bacterial infections have become rare.

New research is uncovering myriad new ways that vitamin D enhances natural immune responses to numerous infections, including tuberculosis, bacteria such as those causing periodontal disease and lung infections, and viruses like the influenza virus. Enhanced immunity against cancer is also an intensive area of research on vitamin D.

Will vitamin D supplementation sufficient to achieve desirable blood levels confer sufficient immunity to swine flu should it come to your door? From what we know and what we’ve seen in the few years of vitamin D experience, I think it will in the majority. But I do believe that we should still heed public health warnings to avoid contact with others, minimize exposure to crowds, avoid travel to affected areas, etc.

Will the real LDL please stand up?

26. April 2009 William Davis (13)

The results of the latest Heart Scan Blog poll are in.

The question: How has your LDL been measured? The 187 responses broke down as:

I have only had a conventional calculated value
108 (57%)

NMR LDL particle number
35 (18%)

Apoprotein B
21 (11%)

Direct LDL cholesterol
21 (11%)

Non-HDL cholesterol
8 (4%)

I don't know what you're talking about
23 (12%)

Remember the TV game show, To Tell the Truth? Celebrities would have to guess which of three guests represented the real person, such as the notorious con man, Frank Abagnale, Jr., or Mad Magazine publisher, William M. Gaines (who stumped celebrity Kitty Carlisle, heard to exclaim, "I never figured it was him. I mean look at the way he's dressed. I was looking for someone who ran a very successful magazine, so I thought it couldn't be him!")

The celebrities playing the game were permitted to ask the three guests a series of questions, hoping to discern who was the real person vs. the two impostors. At the end, each celebrity had to guess who was truly the person of interest. "Will the real Frank Abagnale, Jr. please stand up!"

If we were to act as the celebrities in our LDL game, we quickly discover some telling facts:

--Conventional LDL cholesterol (the only value 57% of our poll respondents have had) is calculated, not measured. LDL is calculated using the 40-year old Friedewald calculation.

--Directly measured LDL cholesterol (the value 11% of respondents had) is just that: directly measured. It eliminates some of the uncertainties of calculated LDL.

--Apoprotein B-Every LDL and VLDL particle produced by the liver contains one apoprotein B molecule. ApoB therefore provides a crude particle count measure of LDL and VLDL particles. Of course, it includes VLDL and is not completely the same as just an LDL measure. Some lipid authorities Like Dr. Peter Kwiterovich have advocated that apoB replace calculated LDL, and that calculated LDL essentially be discarded.

--Non-HDL cholesterol--I mention this more for completeness. Hardly anybody uses this crude value in practice--Indeed, only 4% of our poll respondents had this measure/calculation. Non-HDL is simply total cholesterol minus HDL cholesterol = Non-HDL cholesterol. It is thus a combination of cholesterol in LDL and VLDL (triglycerides), similar to apoprotein B. While, like apoB, it is a bit different in that it includes VLDL, it has proven a superior measure of risk.

--LDL particle number--In my view, this is the gold standard for LDL and risk measurement, obtained by only 18% of our poll respondents. LDL particle number is proving superior for discriminating who is truly at risk for a cardiovascular event, particularly when metabolic syndrome or diabetes is part of the picture, i.e., when HDL and triglycerides are considerably distorted, leading to substantial corruption of calculated LDL.

While 18% is a minority, it still represents growth in recognition that conventional calculated LDL cholesterol is an unreliable, inaccurate, and outdated value. If the real LDL were to stand up, I believe that it is LDL particle number that would spring to its feet.

Vitamin D and inflammation

25. April 2009 William Davis (9)

We already know that vitamin D reduces inflammatory processes, since several markers, including c-reactive protein and IL-6 have previously been shown to drop substantially with vitamin D. Inflammation underlies coronary atherosclerotic plaque growth, as well as plaque rupture that triggers heart attack.

A German group has now shown that the important inflammatory marker, tumor necrosis factor (TNF), is also reduced by vitamin D supplementation. Many studies have implicated increased TNF levels in promoting cancer.

In this study, a modest vitamin D dose of 3320 units (83 micrograms) was given vs. placebo. The 25-hydroxy D level reached in the treated group was 34.2 ng/ml (85.5 nmol/L), which resulted in a 26.5% reduction in TNF compared with 18.7% reduction (?) in the placebo group.

Vitamin D supplementation enhances the beneficial effects of weight loss on cardiovascular disease risk markers.

Zitterman A, Frisch S et al.

BACKGROUND: High blood concentrations of parathyroid hormone and low concentrations of the vitamin D metabolites 25-hydroxyvitamin D [25(OH)D] and calcitriol are considered new cardiovascular disease risk markers. However, there is also evidence that calcitriol increases lipogenesis and decreases lipolysis.
OBJECTIVE: We investigated the effect of vitamin D on weight loss and traditional and nontraditional cardiovascular disease risk markers in overweight subjects.
DESIGN: Healthy overweight subjects (n = 200) with mean 25(OH)D concentrations of 30 nmol/L (12 ng/mL) received vitamin D (83 microg/d) or placebo in a double-blind manner for 12 mo while participating in a weight-reduction program.
RESULTS: Weight loss was not affected significantly by vitamin D supplementation (-5.7 +/- 5.8 kg) or placebo (-6.4 +/- 5.6 kg). However, mean 25(OH)D and calcitriol concentrations increased by 55.5 nmol/L and 40.0 pmol/L, respectively, in the vitamin D group but by only 11.8 nmol/L and 9.3 pmol/L, respectively, in the placebo group.

(Calcitriol = 1,25-dihydroxy vitamin D.)

Knowing your vitamin D blood level is crucial, as individual need for vitamin D varies widely from one person to the next. You can get your vitamin D tested at home by going to Grassroots Health or the Track Your Plaque Marketplace.

Even monkeys do it

24. April 2009 William Davis (6)

It all started back in the 1960s, when ape-watching anthropologists, Drs. Jane Goodall and Richard Wrangham, observed chimps foraging for a specific variety of leaf, which they consumed whole while wrinkling their noses in presumed disgust. Subsequent study showed that the leaves contained a powerful anti-parasitic compound.

A similar observation followed in 1987 by Dr. Michael Huffman from the University of Kyoto. During his year of living in the jungles of Tanzania, he observed chimpanzees in their native habitat. On one unexpected morning, he observed a female chimp, Chausiku:

“Chausiku goes directly to and sits down in front of a shrub and pulls down several new growth branches about the diameter of my little finger. She places them all on her lap and removes the bark and leaves of the first branch to expose the succulent inner pith. She then bites off small portions and chews on each for several seconds at a time. By doing this, she makes a conspicuous sucking sound as she extracts and swallows the juice, spitting out most of the remaining fiber. This continues for 17 minutes, with short breaks as she consumes the pith of each branch in the same manner.”

Dr. Michael Huffman’s description of Chausiku documents a fascinating example of animal self-medication what some call "zoopharmacognosy."
In this instance, the chimpanzee, weak, clutching her back in pain, and listless, was ingesting the leaves of the plant, Vernonia amygdalina, to purge an intestinal parasite. She recovered by the next morning.

Vernonia leaves have since been found to contain over a dozen potential anti-parasitic compounds. Chimps in this region commonly suffer infestations of parasites like Strongyloides fuelleborni (thread worm), Trichuris trichiura (whip worm), and Oesophagostomum stephanostomum (nodular worm). They have somehow stumbled onto a treatment that they administer themselves.

Chimpanzees have inhabited earth for over 6 million years. Who knows how long they and other primates have practiced some form of self-medication.

If chimpanzees can do it, I believe that we, as human primates, can also practice a similar form of self-directed health--homopharmacognosy?

Cath lab energy costs

22. April 2009 William Davis (6)

In honor of Earth Day, I thought I'd highlight the unexpectedly high carbon costs of activities in hospitals, specifically the cardiac catheterization laboratory.

A patient enters the cath lab. The groin is shaved using a plastic disposable razor, the site cleaned with a plastic sponge, then the site draped with an 8 ft by 5 ft composite paper and plastic material (to replace the old-fashioned, reusable cloth drapes). A multitude of plastic supplies are loaded onto the utility table, including plastic sheaths to insert into the femoral artery (which comes equipped with a plastic inner cannula and plastic stopcock), a multi-stopcock manifold that allows selective entry or removal of fluids through the sheath, a plastic syringe to inject x-ray dye, plastic tubing to connect all the devices (total of about 5 feet), and multiple plastic catheters (3 for a standard diagnostic catheterization, more if unusual arterial anatomy is encountered).

All these various pieces come packed in elaborate plastic (polyethylene terephthalate or other polymers) containers, which also come encased in cardboard packaging.

Should angioplasty, stenting, or similar procedure be undertaken, then more catheters are required, such as the plastic "guide" catheters that contain a larger internal lumen to allow passage of angioplasty equipment. An additional quantity of tubing is added to the manifold and stopcock apparatus, as well as a plastic Tuohy-Borst valve to permit rapid entry and exit of various devices into the sheath.

Several new packages of cardboard and plastic are opened which contain the angioplasty balloon, packaging which is usually about 4 feet in length. The stent likewise comes packaged in an 18-inch or so long package with its own elaborate cardboard and plastic housing.

At the conclusion of the procedure, another cardboard/plastic package is opened, this one containing the closure device consisting of several pieces of plastic tubes and tabs.

If the procedure is complicated, the number of catheters and devices used can quickly multiply several-fold.

By the conclusion of the procedure, there are usually two large, industrial-sized trash bins packed full of cardboard, plastic packaging, and discarded tubing and catheters. The trash is so plentiful that it is emptied following each and every procedure. None of it is recycled, given the contamination with human body fluids.

That's just one procedure. The amount of trash generated by these procedures is staggering, much of it plastic. I don't know how much of the U.S.'s annual plastic trash burden of 62 billion pounds (source: EPA) originates from the the cath lab, but I suspect it is a big number in total.

So if you are truly interested in reducing your carbon footprint and doing your part to be "green," avoid a trip (or many) to the cath lab.

Wag the Dog

20. April 2009 William Davis (7)

What if the system to provide heart care has already gotten as big as it should be?

Worse (for hospitals), what if it’s already far larger than it needs to be? Can the system continue to increase revenues if they’ve already attained titanic proportions and outgrown demand? After all, darn it, there are only so many sick people around.

Hospital administrators might have to face an unpleasant choice: downsize to strip excess capacity and suffer the consequences in a competitive market, or . . . fabricate demand for their services.

Like the Dustin Hoffman and Robert DeNiro characters in the movie, Wag the Dog, about how two media-manipulators divert public attention away from a Presidential sex scandal by fabricating a war, spin is everything. It’s enough to sidetrack public attention from a scandal, obscure a truth, send us on a useless detour.

If healthcare for the heart isn’t driven by need, but many still desire to reap the benefits of the procedure-focused system, why not increase the perceived need?

That’s precisely the course that many hospital systems have chosen to follow. If the market you serve has been tapped to its full potential, then grow the market.

Imagine if a company like General Motors were to operate this way. In 2006, for instance, GM sold 9.1 million automobiles. If GM executives were to decide that they’d like to outstrip Toyota by boosting sales by 10% to 10 million, how would they do it? They would first have to determine whether it was feasible to grow demand for their product. If deemed possible, the company would need to ramp up manufacturing capacity to anticipate increased demand. If they miscalculate, GM could be stuck with a costly surplus and have to swallow the costs, maybe selling leftovers at a loss. (We don’t mean to pick specifically on GM; they’re a fine company as far as we’re concerned. This is just a hypothetical illustration.)

But what if a company could concoct some sort of scheme to persuade the car-buying public that they just had to have their cars or trucks? In other words, they could, in effect, create demand for their products.

As perverse as it sounds, that is exactly what occurs in healthcare for heart disease. The system long ago exceeded the necessary level of infrastructure to maintain a high-quality level of care accessible to most Americans. Instead, it continues to grow through a distortion of perception, delivering more services of increasing complexity to larger and larger numbers of people.

The size of the market is therefore a manipulable thing, something that can be massaged and cultivated. There are a variety of clever ways to exaggerate the need for heart procedures.

Why not raise the alarm for heart disease every chance you get? When a local sports figure survived a heart attack here in Milwaukee, St. _____ marketing department was right there, broadcasting the process in TV ads after his recovery. What could be more American than baseball, apple pie . . . and St. _____ Hospital? After his hospital discharge, the 57-year old local icon was shown on the sidelines with his team, back on the job, and at home with family, all beaming, just three months after a bypass operation. “I received only the very best care at St. _____ Hospital. They treated me like family. St. _____ doctors and nurses are the best!” Predictably, a two-month long spike in hospital testing followed filled with people worried whether they, too, might be in imminent danger. Several local cardiologists boasted of the many sports figures who came through the stress testing and heart catheterization labs, though virtually all checked out to be fine.

Though it can serve a legitimate purpose in some situations, stress tests are the ultimate example of a heart scam built on the perception of danger. Pull people in with promises of reassuring them whether or not they have heart disease, only to provide murky results that usually do no such thing. The pitfalls of the test are turned to advantage. The all too common equivocal or mildly abnormal result can be converted into a hospital procedure. (Imagine you could perform such alchemy on the uncertain calculations on your income taxes.)

With millions of stress tests performed every year and the push to perform more and more screening tests, the market has, in effect, been expanded—even though no increase in the disease itself has actually occurred.

Beware: As the scramble for heart patients intensifies, you are going to feel like you are being pulled closer and closer into the jaws of this hungry monster called the American cardiovascular healthcare machine.

Heart scan book

20. April 2009 William Davis (0)

There are only two books on heart scans available.

One, of course, is Track Your Plaque.

The other is the basic book on heart scans, What Does My Heart Scan Show?

Lost in the navigation column to the left on this blog is the link to get the electronic version of the book. In case you didn't know, we make this available for free.

If you're interested, just go here. This book can provide many basic answers to the questions that often arise regarding heart scans, such as the expected rate of increase in score, how your score compares to other people, when should a stress test be considered. Many heart scan centers use this book for educational purposes to help patients understand the importance of their heart scan scores.

(The sign-up for the book requires that an e-mail address be entered.)

The hard copy of What Does My Heart Scan Show? is available from Amazon, also, for $12.99.

Lies, damned lies, and statistics

18. April 2009 William Davis (8)

In the last Heart Scan Blog post, I discussed the question of whether statin drugs provide incremental benefit when excellent lipid values are already achieved without drugs.

But I admit that I was guilty of oversimplification.

One peculiar phenomenon is that, when plaque-causing small LDL particles are reduced or eliminated and leave relatively benign large LDL particles in their place, conventional calculated LDL overestimates true LDL.

In other words, eliminate wheat from your diet, lose 25 lbs. Small LDL is reduced as a result, leaving large LDL. Now the LDL cholesterol from your doctor's office overestimates the true value.

Anne raised this issue in her comment on the discussion:

I eliminated wheat - and all grains - from my diet nearly three years ago (I eat low carb Paleo). My fish oils give me a total of 1680 mg EPA and DHA per day, and my vitamin D levels since last year have varied between 50 ng/ml and 80 ng/ml. However, my lipid profile is not like either John's or Sam's:

LDL cholesterol 154 mg/dl
HDL cholesterol 93 mg/dl
Triglycerides 36 mg/dl
Total cholesterol 255 mg/dl

My cardiologist and endocrinologist are happy with my profile because they say the ratios are good, no one is asking me to take a statin. My calcium score is 0.

However, if we were to measure LDL, not just calculate it from the miserably inaccurate Friedewald equation, we would likely discover that her true LDL is far lower, certainly <100 mg/dl. (My preferred method is the bull's eye accurate NMR LDL particle number; alternatives include apoprotein B, the main apoprotein on LDL.)

So Anne, don't despair. You are yet another victim of the misleading inaccuracy of standard LDL cholesterol determination, a number that I believe should no longer be used at all, but eliminated. Unfortunately, it would further confuse your poor primary care doctor or cardiologist, who--still believe in the sanctity of LDL cholesterol.

By the way, the so-called "ratios" (i.e., total cholesterol to HDL and the like) are absurd notions of risk. Take weak statistical predictors, manipulate them, and try to squeeze better predictive value out of them. This is no better than suggesting that, since you've installed new brakes on your car, you no longer are at risk for a car accident. It may reduce risk, but there are too many other variables that have nothing to do with your new brakes. Likewise cholesterol ratios.

Aspirin, Lipitor, and a low-fat diet

17. April 2009 William Davis (0)

Despite all the hoopla heart disease receives in the media, I continue to marvel at how many people I meet who still think that aspirin, Lipitor, and a low-fat diet constitute an effective heart attack prevention program.

It doesn't. No more than washing your hands prevents all human infections. It helps, but it is a sad substitute for a real prevention program.

Of course, aspirin, Lipitor, and a low-fat diet is the same recipe followed by the unfortunate Tim Russert and his doctors. You know how that turned out. Mr. Russert's experience is far from unique.

What is so magical about aspirin, Lipitor and a low-fat diet?

There is a simple rationale behind this approach. Aspirin doesn't reduce atherosclerotic plaque growth, but it inhibits the propagation of a blood clot on top of a coronary plaque that has "ruptured," thereby reducing likelihood of heart attack (which occurs when the clot fills the artery). So aspirin only provides benefit if and when a plaque ruptures.

Lipitor and other statin drugs reduce LDL cholesterol, promote a modest relaxation of constricted plaque-filled arteries (normalization of endothelial dysfunction), and exerts other effects, such as inflammation suppression.

A low-fat diet is intended to reduce saturated fat that triggers LDL cholesterol formation and to encourage intake of whole grains that reduce cardiovascular events and LDL cholesterol.

If that is the extent of your heart disease prevention program, you will have a heart attack, bypass surgery, or stent--period. It may not be tomorrow or next Friday, or even next month. Aspirin, Lipitor, and a low-fat diet may delay your heart attack or procedure for a few years, but it will not stop it.

Some flaws in the aspirin, Lipitor, low-fat program:

--Aspirin can only exert so much blood clot-blocking effect. It can be overwhelmed by many other factors, such as increased blood viscosity, increased fibrinogen (a blood clotting protein that also triggers plaque), and plaque inflammation.
--Lipitor reduces LDL, but does not discriminate between the relatively harmless large LDL and the truly plaque-triggering small LDL--it reduces all LDL, but small LDL can still persist, even at extravagant levels since neither aspirin nor Lipitor specifically reduces small LDL, while a low-fat diet increases small LDL.
--Low-fat diet--A diet reduced in fat and loaded with plenty of "healthy whole grains" will trigger increased small LDL (an enormous effect), c-reactive protein, high blood sugar, resistance to insulin, high blood pressure, and an expanding abdomen ("wheat belly").

Aspirin, Lipitor and a low-fat diet do not address:

--Vitamin D deficiency
--Omega-3 fatty acid deficiency and the eicosanoid path to inflammation
--High triglycerides
--Small LDL particles
--Distortions of HDL "architecture"
--Lipoprotein(a)--the worst coronary risk factor nobody's heard of
--Thyroid status

In other words, the simple-minded, though hugely financially successful, conventional model of heart disease prevention is woefully inadequate.

Don't fall for it.

Statin drugs for everybody?

17. April 2009 William Davis (10)

Who is better off?

John takes Crestor, 40 mg per day:

LDL cholesterol 60 mg/dl
HDL cholesterol 60 mg/dl
Triglycerides 60 mg/dl
Total cholesterol 132 mg/dl

Or Sam:

LDL cholesterol 60 mg/dl
HDL cholesterol 60 mg/dl
Triglycerides 60 mg/dl
Total cholesterol 132 mg/dl

who obtained these values through vitamin D normalization (to increase HDL); wheat elimination (to reduce triglycerides and LDL); and omega-3 fatty acids (to reduce triglycerides).

Believe the drug industry (motto: If some statin is good, more statin is better!), then John is clearly better off: He has obtained all the "benefits" of statin drugs. They refer to the "pleiotropic" effects of statin drugs, the presumed benefits that extend outside of cholesterol reduction. The most recent example are the JUPITER data that demonstrated 55% reduction in cardiovascular events in people with increased c-reactive protein (CRP). Media reports now unashamedly gush at the benefits of Crestor to reduce inflammation.

However, on Sam's program, elimination of wheat and vitamin D both exert anti-inflammatory effects on CRP, typically yielding drops of 70-90%--consistently, rapidly, and durably.

So which approach is really better?

In my experience, there is no comparison: Sam is far better off. While John will reduce his cardiovascular risk with a statin drug, he fails to obtain all the other benefits of Sam's broader, more natural program. John will not enjoy the same cancer protection, osteoporosis and arthritis protection, relief from depression and winter "blues," and increased mental and physical performance that Sam will.

If our goal is dramatic correction of cholesterol patterns and reduction of cardiovascular risk, for many, many people statin drugs are simply not necessary.

Does the American Heart Association diet reduce heart disease?

5. April 2007 William Davis (0)

If you have a heart attack and land in the hospital where, invariably, you will have a heart procedure. Or, if you get a stent or coronary bypass operation, sometime before your discharge from the hospital, a well-meaning hospital staff dietitian will provide instruction in the American Heart Association (AHA) diet.

Does this diet reduce the risk of heart disease?

The answer depends on where you start. If you begin with a conventional American diet that is enormously influenced by convenience, food manufacturers like Nabisco, General Mills, Quaker Oats, ADM, and Cargill, or food distributors like McDonald’s, Pizza Hut, and Taco Bell, then the American Heart Association diet is indeed an improvement. But just a small one. If LDL cholesterol is the yardstick, the average reduction in LDL is between 10 and 15 mg/dl. This is the same amount of change you’d experience by adding 1 tablespoon of oat bran to your diet. Hardly worth boasting about. HDL, triglycerides, blood glucose, and body weight do not change.

The diet could be substantially better. After all, it’s become common knowledge that other diets, such as the so-called Mediterranean diet, the South Beach Diet, and similar broad projects result in far greater changes than the AHA diet dispensed by your hospital and cardiologist. These diets more effectively reduce LDL, raise HDL, reduce triglycerides, reduce C-reactive protein, reduce blood pressure. Diets like South Beach also yield substantial weight loss and reversal of diabetic tendencies, with the magnitude of benefit dependent on the amount of weight lost.

Why this stubborn adherence to the outdated concepts articulated in the AHA diet? Cardiologists would argue that insufficient data has been generated to permit widespread application of these diets. They also differ on whether they really work. Of course, the majority remain ignorant and dismiss them as fad diets.

A little digging into the financial disclosures of the AHA suggests another, more malignant influence: who is paying the bills? Until recently, drug manufacturers were major contributors to the AHA. However, more recently AHA administrators have become sensitive to the public perception that they might be nothing more than a voice box for the drug industry. They have since limited contributions from the drug companies to 8% of annual charitable revenues.

The drug manufacturers have been replaced by the food industry. In addition to food manufacturers that make the cereals on your grocery shelf, it includes the multi-national conglomerates that produce unimaginable revenues and carry enormous political clout, like ADM and Cargill. Ever wonder how it is that Honey Nut Cheerios received a “Heart Healthy” endorsement from the AHA?

The AHA diet does not provide the answers we’re looking for, not even close. It is a perversion from an organization that has its strings pulled by industry. The answers to health will not come from the AHA, AMA, the American College of Cardiology, the American Hospital Association, and it won’t come from your doctor. It won’t come from a titillating report on the evening news or Good Morning America. It will come from collective and expanding wisdom placed directly into the hands of the public. It will be untainted by the temptation of drug industry dollars. It will not be dirtied by million dollar contributions, or the multi-million dollar behind-closed-doors lobbying of the food manufacturers. It will come from the truth relayed to the healthcare-consuming public. I hope you recognize it when you see it.

If you want a healthy diet for your heart, throw away the pamphlets from the AHA unless you are partial to bread, breakfast cereals, corn, and the supporters of their misguided nutritional advice.
