Dr. Reinhold Vieth on vitamin D

A Track Your Plaque member brough the following webcast to our attention:

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

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

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

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

Vitamin D on Good Morning America


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

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

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

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

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

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

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

Would you bet your life on chelation?


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

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

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

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

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

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

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

The powerful forces preserving the status quo


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


Politics and Profits

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


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

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

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

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

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

Do stents prevent reversal?

I've seen this phenomenon several times now: A highly-motivated Track Your Plaque participant with a stent in one artery will do all the right things--lose weight, achieve 60:60:60 in basic lipids, identify and correct hidden lipoprotein disorders, take fish oil, correct vitamin D, etc.

Follow-up heart scan shows dramatic reduction in scoring in the two arteries without stents--30% per artery. But the artery with the stent will show marked increase in scoring above and/or below the stent. (It's impossible to tell what happens in or around the stent itself from a calcium scoring standpoint, since steel looks just like calcium on a CT heart scan.) In other words, there is marked plaque growth in the vicinity of the stent, despite the fact that dramatic reversal of atherosclerosis has occurred in other arteries without stents.

Should we take this to mean that a stent destroys the opportunity for atherosclerotic plaque reversal in the stented artery? I don't know, but I fear this may be true. What dangers does this different sort of plaque pose? Is it the result of the injury imposed at time of stent implantation, some modification of flow or biologic responses as a result of the presence of the stent?

These are all unanswered questions. But I believe that it is yet another suggestive piece of evidence that the best stent is no stent at all.

At what score should I have a heart cath?

This question comes up frequently: At what specific heart scan score should a heart catheterization be performed? In other words, is there a specific cut-off that automatically triggers a need for catheterization?

In my view, there is no such score. We can't say, for instance, that everybody with a score above 1000 should have a catheterization. It is true that the higher your score, the greater the likelihood of a plaque blocking flow. A score of 1000 carries an approximately 25-30% likelihood of reduced blood flow sufficient to consider a stent or bypass. This can nearly always be settled with a stress test. Recall that, despite their pitfalls for uncovering hidden heart disease in the first place, stress tests are useful as gauges of coronary blood flow.

But even a score of 1000 carries a 70-75% likelihood that a procedure will not be necesary. This is too high to justify doing heart catheterizations willy-nilly.

Unfortunately, some my colleagues will say that any heart scan score justifies a heart cath. I believe this is absolutely, unquestionably, and inexcusably wrong. More often than not, this attitude is borne out of ignorance, laziness, or a desire for profit.

Does every lump or bump justify surgery, radiation, and chemotherapy on the chance it could represent cancer? Of course not. There is indeed a time and place for these things, but judgment is involved.

In my view, no heart scan score should autmatically prompt a major heart procedure like heart catheterization in a person without symptoms.

Niacin makes NY Times

In the wake of the crash and burn of Pfizer's torcetrapib, media attention has turned up the miracles of . . .good old niacin. The NY Times carried a well-written report on niacin in its recent report, An Old Cholesterol Remedy Is New Again.


(Read the entire report at http://www.nytimes.com/2007/01/23/health/23consume.html?em&ex=1169701200&en=670fa84ae2ea648c&ei=5087%0A)

Among their comments:

...torcetrapib worked primarily by increasing HDL, or good cholesterol. Among other functions, HDL carries dangerous forms of cholesterol from artery walls to the liver for excretion. The process, called reverse cholesterol transport, is thought to be crucial to preventing clogged arteries.

Many scientists still believe that a statin combined with a drug that raises HDL would mark a significant advance in the treatment of heart disease. But for patients now at high risk of heart attack or stroke, the news is better than it sounds. An effective HDL booster already exists.

It is niacin, the ordinary B vitamin.

In its therapeutic form, nicotinic acid, niacin can increase HDL as much as 35 percent when taken in high doses, usually about 2,000 milligrams per day. It also lowers LDL, though not as sharply as statins do, and it has been shown to reduce serum levels of artery-clogging triglycerides as much as 50 percent. Its principal side effect is an irritating flush caused by the vitamin’s dilation of blood vessels.

Despite its effectiveness, niacin has been the ugly duckling of heart medications, an old remedy that few scientists cared to examine. But that seems likely to change.

“There’s a great unfilled need for something that raises HDL,” said Dr. Steven E. Nissen, a cardiologist at the Cleveland Clinic and president of the American College of Cardiology. “Right now, in the wake of the failure of torcetrapib, niacin is really it. Nothing else available is that effective.”

In 1975, long before statins, a landmark study of 8,341 men who had suffered heart attacks found that niacin was the only treatment among five tested that prevented second heart attacks. Compared with men on placebos, those on niacin had a 26 percent reduction in heart attacks and a 27 percent reduction in strokes. Fifteen years later, the mortality rate among the men on niacin was 11 percent lower than among those who had received placebos.

'Here you have a drug that was about as effective as the early statins, and it just never caught on,' said Dr. B. Greg Brown, professor of medicine at the University of Washington in Seattle. 'It’s a mystery to me. But if you’re a drug company, I guess you can’t make money on a vitamin.'



Of course, you and I don't have to wait for the media to endorse something. I'm nonetheless thrilled that this hugely helpful vitamin is gaining greater recognition. My preferred form nowadays is over-the-counter SloNiacin (Upsher Smith). Weve seen no liver side-effects and a minimal quantity of flushing. It's also reasonably priced, $13.99 for 100 tablets of 500 mg at Walgreen's. That's a lot cheaper than prescription Niaspan at $130 for 60 tablets.

Perhaps the notoriety will cut back on the silly responses from some physicians that I still hear about from patients: "My doctor said to stop the niacin because it's going to destroy my liver."

Wheat: the nicotine of food

Yes, we know that wheat contributes to creating small LDL, drops HDL, raises triglycerides, and VLDL. We also know it indirectly slows the clearance of after-eating fats from the blood (curious, I know). Wheat products also increase inflammation (C-reactive protein), raise blood sugar, and contribute tremendously to diabetes.

What many people don't know is that wheat products also have an addictive quality: have one donut and you want another. It's true for bread, breakfast cereals, pretzels, cookies, etc. How many times have you had just one Oreo cookie?

Curiously, elimination of wheat products, unlike elimination of nicotine, usually causes the cravings to disappear. In other words, if you stop smoking cigarettes, the desire to smoke doesn't go away. With wheat products, the often overwhelming desire for more wheat products often just goes away.

But most people are simply unable to dramatically reduce or eliminate wheat products from their daily diet and therefore struggle each and every day with excessive cravings for bagels, donuts, cookies, breads, etc.

Try this useful experiment: Eliminate wheat products for a month and see what happens. Most people drop blood pressure, lose the tummy excess, feel more alert, see a drop in blood sugar, experience improvements in lipoproteins, and regain control over appetite.

Good time for a heart attack?

Man Has Heart Attack At Right Place, Right Time

If Robert Ricard had picked the wrong restaurant for lunch, he might have died.

The 71-year-old Michigan man suffered a heart attack shortly after ordering a glass of wine with friends at Bentley's Roadhouse on Saturday.

Luckily, a disaster medical team was sitting nearby.



A TV station in Michigan reported the above story. You've heard these "if it wasn't for ___, so and so would have died" stories. They're reported in all cities at one time or another.

What amazes me about these common local stories is that they're accepted at all. The question that comes to my mind is "Why couldn't the heart attack have been averted in the first place?" Early identification then, as close as humanly possible, elimination of risk would have been a preferable path.

Of course, it may not be the role of the media to cast judgement on why and how the entire episode could have been completely prevented from occurring. But you shouldn't fall into the same trap of complacency. We cannot expect others to save us when the "big one" hits. Your best assurance is to never have one in the first place.

How good is the South Beach Diet?

I'm a fan of the South Beach Diet.

Though it is billed as a program for weight loss (for which it is very effective), it is really a program for health. The basic approach of South Beach involves:

Eat good fats — Choose good fats from olive oil, canola oil, peanut oil, flaxseed oil, walnut oil, avocados, nuts, and fish. Omega-3 (fish oil) supplements are also fine.


Eat good carbs — Good carbs include high-fiber, nutrient-dense fruits, vegetables, legumes, and whole grains.

Eat lean protein — Good sources include eggs, low-fat dairy, nuts, seeds, legumes, skinless white-meat poultry, fish, shellfish, lean cuts of meat, and vegetarian options such as tofu.

(From The South Beach Diet, Dr. Arthur Agatston)


There's no doubt that South Beach can yield dramatic weight loss. In my experience, the success in weight loss depends on 1) how unhealthy your diet was in the first place, and 2) how long you can stick to Phase I, the inital phase during which weight loss is most dramatic. Some people have to periodically cycle back to Phase I to break a "plateau" or to lose faster.

But South Beach is also healthy. It has all the ingredients of a healthy eating program: Low saturated and hydrogenated fats, rich in monounsaturated fats, high fiber, low- to moderate- glycemic index, vegetables and fruits, lean proteins.

The Atkins' diet, in contrast, while very effective for weiglht loss, is an unhealthy process. I've seen lots of bladder infections, constipation, skin rashes, and kidney stones. That's just in the short term. If you stick to the "induction phase" (the no carbohydrate, low fiber, indiscriminate fat initial phase) for an extended period, I suspect that other adverse internal phenemena also develop that might not show for years, like cancer. But--it does work for weight loss!

South Beach's Phase I is also carbohydrate restricted, but steers you towards healthier foods, such as healthy oils from olive and canola, raw or dry roasted nuts, and lean proteins and vegetables.

What really makes South Beach special, however, are its clever recipes. Dr. Arthur Agatston (the author) involved chefs from the restaurants in the South Beach area of Miami to help create healthy yet delicious recipes. We've tried many of them and, while they are different from traditional fare, are delicious and satisfying for the most part.

Criticisms? None, really. But, when my patients choose South Beach (which I often encourage), I often have to impress on them that the Track Your Plaque program is not about weight loss. It is about seizing control of a potentially life-threatening disease. It is a far more important goal with greater implications. Weight loss is just one aspect of a coronary plaque control effort. For this reason, we sometimes have to make changes in the South Beach program to allow for correction of specific lipoprotein patterns.

The most common modification is in people with small LDL particles. This pattern often does indeed respond to weight loss and/or niacin. However, it occasionally persists despite these efforts. We then will ask the patient to continue to restrict the re-introduction of wheat products, though it is allowed after Phase I in South Beach. In other words, for this specific and sometimes difficult to control lipoprotein pattern, a spedific modification of the off-the-shelf South Beach program is sometimes necessary. Of course, the diet is created to suit everybody. Lipoprotein analysis permits detailed insight into your patterns and it's only to be expected that specific modifications might be needed.

But, as written, you can do quite well in your plaque control program by sticking to South Beach.

I'll supply the tar if you supply the feathers

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


DIRECT-TO-CONSUMER PHARMACEUTICAL ADVERTISING HAS:

Increased public awareness of medical conditions and their treatment
19 (11%)

Has had little overall effect on health and healthcare
29 (18%)

Needlessly increased healthcare costs
81 (50%)

Further empowered the revenue-obsessed pharmaceutical industry
130 (81%)


Clearly, there's a lot of negative sentiment against direct-to-consumer (DTC) drug advertising.

It looks as if a small minority believe that good has come from DTC advertising, judging by the meager 11% who voted for increased awareness. In fact, the poll results are heavily weighed towards the negative: 50% voted for "needlessly increased healthcare costs," while an astounding 81% voted for "empowered the revenue-obsessed pharmaceutical industry."

It is, indeed, an odd situation: Pharmaceutical agents available only by prescription being hyped directly to the consumer.

Personally, I would vote for choices 1,3, and 4. While awareness has increased, it has come with a hefty price, not all of it well spent. I believe the pharmaceutical industry still adheres to the rule that, for every $1 spent on advertising, $4 is made in revenue. They are, in effect, printing money.

What goes up can't come down

According to conventional wisdom, heart scan scores cannot be reduced.

In other words, say you begin with a heart scan score of 300. Conventional wisdom says you should take aspirin and a statin drug, eat a low-fat "heart healthy" diet, and take high blood pressure medications, if necessary.

If your heart scan score goes up in a year or two, especially at an annual rate of 20% or more, then you are at very high risk for heart attack. If the heart scan score stays the same, then your risk is much reduced. These observations are well-established.

But more than 99% of physicians will tell you that reducing your heart scan score is impossible. Don't even try: Heart scan scores can go up, but they can't go down.

Baloney. Heart scan scores can indeed go down. And they can go down dramatically.

It is true that, following conventional advice like taking a statin drug, following a low-fat diet, and taking aspirin will fail to reduce your heart scan score. A more rational approach that 1) identifies all causes of coronary plaque, 2) corrects all causes while including crucial strategies like omega-3 fatty acid supplementation, vitamin D supplementation, and thyroid function normalization, is far more likely to yield a halt or reduction in score.

While not everybody who undertakes the Track Your Plaque program will succeed in reducing their heart scan score, a growing number are enjoying success.

A small portion of our experience was documented this past summer. (I collected and analyzed the data with the help of Rush University nutrition scientist, Dr. Susie Rockway, and statistician, Dr. Mary Kwasny.)


Effect of a combined therapeutic approach of intensive lipid management, omega-3 fatty acid supplementation, and increased serum 25 (OH) vitamin D on coronary calcium scores in asymptomatic adults.

Davis W, Rockway S, Kwasny M.

The impact of intensive lipid management, omega-3 fatty acid, and vitamin D3 supplementation on atherosclerotic plaque was assessed through serial computed tomography coronary calcium scoring (CCS). Low-density lipoprotein cholesterol reduction with statin therapy has not been shown to reduce or slow progression of serial CCS in several recent studies, casting doubt on the usefulness of this approach for tracking atherosclerotic progression. In an open-label study, 45 male and female subjects with CCS of > or = 50 without symptoms of heart disease were treated with statin therapy, niacin, and omega-3 fatty acid supplementation to achieve low-density lipoprotein cholesterol and triglycerides < or = 60 mg/dL; high-density lipoprotein > or = 60 mg/dL; and vitamin D3 supplementation to achieve serum levels of > or = 50 ng/mL 25(OH) vitamin D, in addition to diet advice. Lipid profiles of subjects were significantly changed as follows: total cholesterol -24%, low-density lipoprotein -41%; triglycerides -42%, high-density lipoprotein +19%, and mean serum 25(OH) vitamin D levels +83%. After a mean of 18 months, 20 subjects experienced decrease in CCS with mean change of -14.5% (range 0% to -64%); 22 subjects experienced no change or slow annual rate of CCS increase of +12% (range 1%-29%). Only 3 subjects experienced annual CCS progression exceeding 29% (44%-71%). Despite wide variation in response, substantial reduction of CCS was achieved in 44% of subjects and slowed plaque growth in 49% of the subjects applying a broad treatment program.

Gretchen's postprandial diet experiment

Gretchen sent me the results of a little experiment she ran on herself. She measured blood glucose and triglycerides after 1) a low-fat diet and 2) a low-carb diet.









Gretchen describes her experience:

Several years ago I received a windfall of triglyceride strips that would expire in a week or so. I hated to waste them, so I decided to use them to test my triglyceride and BG responses to two different diets: low carb and low fat.

The first day I followed a low-fat diet. For breakfast I ate a lot of carbohydrate, including 1 oz of spaghetti cooked al dente and ¾ cup of white rice. For the rest of the day I ate less carbohydrate but continued to eat low fat.

The second day I followed a low-carb diet. For breakfast I ate a lot of fat, including a sausage, mushrooms fried in butter, 2 slices of bacon, and ¼ cup of the creamy topping of whole-milk yogurt. For the rest of the day I ate less fat, especially less saturated fat, but continued to eat low carb.

Both days I measured both BG and triglyceride levels every hour until I went to bed. On the low-carb day I had 3 meals. On the low-fat day, I was constantly hungry, had 4 meals, and kept snacking.

You can see the results in Figure 1. On the low-fat diet, after a “healthy” low-fat breakfast of low-glycemic pasta with low-fat sauce, my BG levels shot up to over 200 mg/dL and took more than 6 hours to come down. My triglycerides, however, remained low, and at first I thought perhaps the low-fat diet might be better overall. However, after about 6 hours, the triglyceride levels started to increase steadily, and by the next morning, they were higher than they had been the day before.
On the low-carb diet, my BG levels stayed low all day. However, after meals, the triglyceride levels skyrocketed. After meals they came down, and by the next morning they were lower than they had been the day before.

As I interpret these results, the high triglyceride levels after eating the high-fat meals represent chylomicrons, the lipoproteins that transport fat from your meals to the cells of your body. The high triglyceride levels the morning after eating the low-fat meals represent very low density lipoprotein, which takes the cholesterol your liver synthesizes when your intake of dietary cholesterol is low and distributes it to cells that need it, or again, to the fat for storage.

There are several interesting factors to consider here. First, when you have a lipid test done at the lab, it’s usually done fasting, which means first thing in the morning after not eating for 8 to 12 hours. It tells you nothing about what your triglyceride levels were all day.

Second, the low-carb diet resulted in lower fasting triglyceride levels, but much higher postprandial triglyceride levels. Which are more dangerous? I’m afraid I don’t know. You should also note that the high-fat, low-carb breakfast was extremely high in fat, including saturated fat. I don’t normally eat that much fat but wanted to test extremes.

Third, although the low-fat diet didn’t produce the very high postprandial triglyceride levels that the high-fat diet did, it produced extremely high BG levels that persisted for 6 hours. Some people think that it’s oxidized and glycated lipids that are the dangerous ones, so high BG levels and normal triglyceride levels might be more dangerous than very high triglyceride levels and normal BG levels. Note that high BG levels also contribute to oxidation rates.

Fourth, this shows the results of an experiment with a sample size of one. My physiology might not be typical. If you want to know how your own body’s lipids respond to different types of diets, you should get a lipid meter and test yourself. Unfortunately, your insurance is unlikely to want to pay for this, so it will be an expensive experiment.

The main point of this is that the results of different diets are complex. We have to eat. And what we eat can affect many different systems in our bodies. Finding the ideal diet that matches our own physiology and results in the best lipid levels as well as BG levels is a real challenge.



This was a lot of effort for one person. Thanks to Gretchen for sharing her interesting experience.

Gretchen makes a crucial point: Some of the effects of diet changes evolve over time, much as triglyceride levels changed substantially for her on the day following her experiment. Wouldn't it be interesting to see how postprandial patterns develop over time if levels were observed sequentially, day after day?

The stark contrast in blood sugars is impressive--Low-carb clearly has the advantage here. Are there manipulations in diet composition in low-carb meals that we can make to blunt the early (3-6 hour) postprandial lipoprotein (triglyceride) peak? That's a topic we will consider in future.

More of Gretchen's thoughts can be found at:

After-eating effects: Carbohydrates vs. fats

In the ongoing debate over whether it's fat or carbohydrate restriction that leads to weight loss and health, here's another study from the Oxford group examining the postprandial (after-eating) effects of a low-fat vs. low-carbohydrate diet. (Roberts R et al, 2008; full-text here.)

High-carbohydrate was defined as 15% protein; 10% fat; 75% carbohydrate (by calories), with starch:sugar 70:30.

High-fat was defined as 15% protein; 40% fat; 45% carbohydrate, with starch:sugar 70:30. (Yes, I know. By our standards, the "high-fat" diet was moderate-fat, moderate-carbohydrate--too high in carbohydrates.)

Blood was drawn over 6 hours following the test meal.




Roberts R et al. Am J Clin Nutr 2008

The upper left graph is the one of interest. Note that, after the high-carbohydrate diet (solid circles), triglyceride levels are twice that occurring after the high-fat diet (open circles). Triglycerides are a surrogate for chylomicron and VLDL postprandial lipoproteins; thus, after the high-carbohydrate diet, postprandial particles are present at much higher levels than after the high-fat diet. (It would have been interesting to have seen a true low-carbohydrate diet for comparison.) Also note that, not only are triglyceride levels higher after high-carbohydrate intake, but they remain sustained at the 6-hour mark, unlike the sharper decline after high-fat.

It's counterintuitive: Postprandial lipoproteins, you'd think, would be plentiful after ingesting a large quantity of fat, since fat must be absorbed via chylomicrons into the bloodstream. But it's carbohydrates (and obesity, a huge effect; more on that in future) that figure most prominently in determining the pattern and magnitude of postprandial triglycerides and lipoproteins. Much of this effect develops by way of de novo lipogenesis, the generation of new lipoproteins like VLDL after carbohydrate ingestion.

We also see this in our Track Your Plaque experience. Rather than formal postprandial meal-testing, we use intermediate-density lipoprotein (IDL) as our surrogate for postprandial measures. A low-carbohydrate diet reduces IDL dramatically, as do omega-3 fatty acids from fish oil.

The Paleo approach to meal frequency

Furthering our discussion of postprandial (after-eating) phenomenona, including chylomicron and triglyceride "stacking" (Grazing is for cattle and Triglyceride and chylomicron stacking), here's a comment from the recent Palet Diet Newsletter on the closely related issue, meal timing and frequency:


We are currently in the process of compiling meal times and patterns in the worlds historically studied hunter-gatherers. If any single picture is beginning to emerge, it clearly is not three meals per day plus snacking ala the typical U.S. grazing pattern. Here are a few examples:

--The Ingalik Hunter Gatherers of Interior Alaska: 'As has been made clear, the principal meal and sometimes the only one of the day is eaten in the evening.'
--The Guayaki (Ache) Hunter Gatherers of Paraguay: 'It seems, however, that the evening meal is the most consistent of the day. This is understandable, since the day is generally spent hunting for food that will be eaten in the evening."
--The Kung Hunter Gatherers of Botswana. "Members move out of camp each day individually or in small groups to work through the surrounding range and return in the evening to pool the collected resources for the evening meal."
--Hawaiians, Tahitians, Fijians and other Oceanic peoples (pre-westernization). 'Typically, meals, as defined by Westerners, were consumed once or twice a day. . . Oliver (1989) described the main meal, usually freshly cooked, as generally eaten in the late afternoon after the day’s work was over."

The most consistent daily eating pattern that is beginning to emerge from the ethnographic literature in hunter-gatherers is that of a large single meal which was consumed in the late afternoon or evening. A midday meal or lunch was rarely or never consumed and a small breakfast (consisting of the remainders of the previous evening meal) was sometimes eaten. Some snacking may have occurred during daily gathering, however the bulk of the daily calories were taken in the late afternoon or evening. This pattern of eating could be described as intermittent fasting relative to the typical Western pattern, particularly when daily gathering or hunting were unsuccessful or marginal. There is wisdom in the ways of our hunter gatherer ancestors, and perhaps it is time to re-think three squares a day.



In other words, the notion of "grazing," or eating small meals or snacks throughout the day, is an unnatural situation. It is directly contrary to the evolutionarily more appropriate large meal followed by periods of no eating or small occasional meals.

I stress this point because I see that the notion of grazing has seized hold of many people's thinking. In my view, grazing is a destructive practice that is self-indulgent, unnecessary, and simply fulfills the perverse non-stop hunger impulse fueled by modern carbohydrate foods.

Eliminate wheat, cornstarch, and sugars and you will find that grazing is a repulsive impulse that equates with gorging.

Even mummies do it


Lady Rai, nursemaid to Queen Nefertari of Egypt, died in 1530 BC, somewhere between the age of 30 and 40 years. Her mummy is preserved in the Egyptian National museum of Antiquities in Cairo.

A CT scan of her thoracic aorta revealed calcium, representing aortic atherosclerosis, reported by Allam et al (including my friend from The Wisconsin Heart Hospital, Dr. Sam Wann, who provided me a blow-by-blow tale of this really fascinating project). Ladi Rai and 14 other Egyptian mummies were found to have vascular calcification of a total of 22 mummies scanned. (The hearts of the mummies were too degenerated to make out any coronary calcium.)

But why would people of that age have developed atherosclerosis?

The authors of the study comment that "Our findings that atherosclerosis was not infrequent among middle-aged and older ancient Egyptians of high social status challenges the view that it is a disease of modern humans. . . Although ancient Egyptians did not smoke tobacco or eat processed food or presumably lead sedentary lives, they were not hunter-gatherers. [Emphasis mine.] Agriculture was well established in ancient Egypt and meat consumption appers to have been common among those of high social status."

Fascinating. But I don't think that I'd blame meat consumption. Egyptians were also known to have cultivated grains, including wheat, and frequently consumed such sweet delicacies as dates and figs. Egyptians were also apparently beer drinkers. Unfortunately, no beer steins were seen in any of the scans.

Life Extension article on iodine

Here's a link to my recent article in Life Extension Magazine on iodine:

Halt on Salt Sparks Iodine Deficiency

Iodized salt, a concept introduced into the U.S. by the FDA in 1924, slowly eliminated goiter (enlarged thyroid glands), along with an enormous amount of thyroid disease, heart attack, mental impairment, and death. The simple addition of iodine to salt ensured that salt-using Americans obtained enough iodine sufficient to not have a goiter.

Now that the FDA, goiters long forgotten from their memories, urges Americans to reduce salt, what has happened to our iodine?

I talk at length about this issue in the Life Extension article.

The healthiest people are the most iodine deficient

Here's an informal observation.

The healthiest people are the most iodine deficient.

The healthier you are, the more likely you are to:

--Avoid junk foods--30% of which have some iodine from salt
--Avoid overuse of iodized salt
--Exercise--Sweating causes large losses of iodine.

So the healthy-eating, exercising person is the one most likely to show iodine deficiency: gradually enlarged thyroid gland (in the neck), declining thyroid function. Over time, if iodine deficiency persists, excessive sensitivity to iodine develops, as well as abnormal thyroid conditions like overactive nodules.

Even subtle levels of thyroid dysfunction act as a potent coronary risk factor.

It's the score, stupid

Sal has had 3 heart scans. (He was not on the Track Your Plaque program.) His scores:

March, 2006: 439

April, 2007: 573

October, 2009: 799

Presented with the 39% increase from April, 2007 to October, 2009, Sal's doctor responded, "I don't understand. Your LDL cholesterol is fine."

This is the sort of drug-driven, cholesterol-minded thinking that characterizes 90% of primary care and cardiologists' practices: "Cholesterol is fine; therefore, you must be fine, too."

No. Absolutely not.

The data are clear: Heart scan scores that continue to increase at this rate predict high risk for cardiovascular events. Unfortunately, when my colleagues hear this, they respond by scheduling a heart catheterization to prevent heart attack--a practice that has never been shown to be effective and, in my view, constitutes malpractice (i.e., performing heart procedures in people with no symptoms and with either no stress test or a normal stress test).

It's the score, stupid! It's not the LDL cholesterol. Pay attention to the increasing heart scan score and you will know that the disease is progressing at an alarming rate. Accepting this fact will set you and your doctor on the track to ask "Why?"

That's when you start to uncover all the dozens of other reasons that plaque can grow that have nothing to do with LDL cholesterol or statin drugs.

Dr. Bill Blanchet: A ray of sunshine

Another heated discussion is ongoing at The Heart.org, this one about Tim Russert's untimely death: Media mulls Russert's death as cardiologists weigh in

Although I posted a couple of brief comments there, I quickly lost patience with the tone of many of the other respondents. Should you choose to read the comments, you will see that many still cling to old notions like heart attack is inevitable, defibrillators should be more widely available, "vulnerable" plaques cannot be identified before heart attacks, etc.

I quickly lose patience with this sort of outdated rhetoric. However, our good friend, Dr. Bill Blanchet of Boulder, Colorado, has a far stronger stomach for this than I do.

Here, a sample of his wonderfully persuasive comments:


Heart disease cannot be stopped but we can certainly do better!

Goals we must achieve if we hope to solve the Rube Goldberg of coronary disease:

1. Find something more reliable than Framingham risk factors to determine who is at risk. Framingham risk factors are wrong more often than they are right. If you are comfortable treating 40% of the patients destined to have heart attacks, continue to rely on “traditional” risk factors only.

2. Treat to new standards beyond NCEP/ATP-III. These accepted standards prevent at best 40% of heart attacks in patients treated. This is unacceptable, and arguably why Tim is dead today! Why prevention protocols emphasize LDL and more or less ignore HDL, triglycerides and underemphasize blood pressure eludes me.

3. Motivate patients to participate in coronary prevention. Saying “you need to get exercise and lose weight” is not adequate motivation, it hasn't worked to date and probably won't work tomorrow. If you are satisfied saying it is "the patient's fault for not listening to me" so be it, that excuse doesn't work for me!

Currently “good results” consist of being able to convince 50% of patients at risk by traditional risk factors to participate in prevention and hopefully 30% will be treated to goal. Of those treated to goal, 60% of the heart attacks will still happen anyway. Mathematically we can hope to prevent <10% of heart attacks with this approach!

I have personally found a solution to this dilemma. It goes like this:

1. EBT-CAC [electron-beam tomography coronary artery calcium] is the most reliable predictor of coronary events period, the end! Anyone who disagrees has not objectively read the literature. The only test more predictive than the initial calcium score is the follow up score 12 to 36 months later. EBT predicted Tim Russert’s event 10 years before it happened; passing his stress test gave him inappropriate reassurance 2 months before he died. If only Tim had the benefit of a second EBT sometime over the last 10 years he and his doctor would have known that what they were doing was insufficient and improvements could have been made.

2. I treat to the standard of stable calcified plaque by EBT (<15% annualized progression, preferably <1% annualized progression). This correlates with a very low incidence of coronary events. Even the ACC/AHA 2007 position paper agrees with this. This is accomplished with aspirin, omega-3 fatty acids, diet, exercise, weight control, smoking cessation, treatment of sleep apnea, stress reduction, control of HDL, triglycerides and LDL cholesterol and excellent control of BP and insulin resistance plus the recent addition of vit D-3. Meeting an LDL goal of 70 is easy but prevents only a minority of events, treating to the goal of stable CAC by EBT is a challenge but when achieved, the reward is near elimination of heart attacks and ischemic strokes. This has indeed been my personal experience!

3. A picture of plaque in the coronary artery is a monumental motivator for patients to get on board to make things better. The demonstration of progression of that plaque despite our initial therapies gets all but a few suicidal patients interested in doing a better job. I think that similar motivational results can be had with carotid imaging; the difference is that CAC by EBT is clinically validated as being a much stronger predictor of events with progression and non-events with stability than any ultrasound test including IVUS.



Wow! I couldn't have said it better.

Sadly, I doubt even Dr. Blanchet's persuasive words will do much to convince my colleagues on this forum. And the cardiologists on this forum are likely among the more inquisitive and open-minded. The ones stuck in the cath lab day and night, or implanting defibrillators, are even less inclined to entertain such conversations.

While I admire Dr. Blanchet's energy for continuing to argue with my colleagues, the lesson I take is: Take charge of health yourself. If you wait for your doctor to do it for you, you could be in the same situation as poor Tim Russert. This is an age when your physician should facilitate your success, not prevent it or leave you wallowing in ignorance.

The Russert Protocol at work

Without a concerted effort at prevention, heart scan scores (coronary calcium scores) grow like weeds. The average rate of growth is 30% per year.

Keith is an illustrative case. At age 39, Keith's heart scan score was 29, in the 99th percentile due to his young age. (In other words, young people before age 40 have no business having plaque. If they do, it's bad.)

True to conventional practice, Keith's doctor prescribed a cholesterol drug (Zocor), asked him to take a baby aspirin, and prescribed a blood pressure medicine. He asked Keith to cut the fat in his diet. His doctor even exceeded conventional (ATP-III) LDL cholesterol treatment targets.

Keith, an intelligent and motivated businessman, happily complied with his doctor's instructions. Eighteen months later, a 2nd heart scan showed a score of 68, representing an increase of 135%, or 76% per year.

This is the very same approach that the late Mr. Tim Russert's doctors employed: treat (calculated) LDL cholesterol with a statin drug, treat high blood pressure, reduce saturated fat, take aspirin. It was a miserable failure in Keith, whose plaque continued to grow at a frightening rate of 76% per year. It was also an obvious failure in poor Tim Russert.

Further investigation in Keith uncovered:

--Severe small LDL--80% of all LDL was small (despite a favorable HDL of 58 mg/dl)
--Measured LDL particle number (NMR) showed that "true" LDL was actually about 60 mg/dl higher than suggested by the crude calculated LDL
--An after-eating (postprandial) disorder (IDL)
--A pre-diabetic blood sugar and insulin
--Severe vitamin D deficiency
--Very low testosterone

All these patterns were present despite the steps Keith and his doctor had instituted. It's no wonder his plaque was undergoing explosive growth.

The conventional approach to coronary disease prevention is inadequate, more often than not a mindless adherence to one-size-fits-all template crafted to a great degree by drug industry interests and "experts" who often stand at arm's length from real live patients.

Keith's "residual" abnormalities are all readily correctable. He has since made dramatic improvements in all parameters. Among the strategies used is a wheat- and cornstarch-free diet that resulted in 12 lbs lost within the first few weeks of effort.

If you are on the "Russert Protocol," have a serious conversation with your doctor about the continued advisability of remaining on this half-assed approach to heart disease. Or, consider finding another doctor.

Petition to the National Institutes of Health

A petition to the National Institutes of Health (NIH) is being circulated in response to the mis-statement made in an NIH-sponsored study, ACCORD.

The ACCORD Trial included over 10,000 type II diabetics and compared an intensive, multiple-medication group to achieve a target HbA1c of <6.0%, with a less intensively treated group with a target HbA1c of 7-7.9%. (HBA1c is a long-term measure of glucose, averaging approximately the last 3 months glucose levels.) To the lead investigators' surprise, the intensively treated group experienced more death and heart attack than the less intensive group. The conclusion suggested that intensive management of diabetes may not be a desirable endpoint and may result in greater risk for adverse events.

The petitioners argue that the problem was not with intensive glucose control per se, but the use of multiple side-effect-generating medications. Unfortunately, the ACCORD conclusions give the impression that loose control over blood sugar may be desirable.

The petition originates from the Nutrition and Metabolism Society, a non-profit organization seeking to promote carbohydrate restriction.


The petition reads:

National Institute of Health re: the ACCORD Diabetes Study: "Intensively targeting blood sugar to near-normal levels ... increases risk of death. "

This statement is untrue. This study lowered blood glucose levels only by aggressive drug treatment.

Preventative measures and proven non-drug treatments are being ignored by the NIH, ADA and many other governing agencies.

There is abundant scientific evidence proving a carbohydrate restricted diet can be as effective as drugs in lowering blood glucose levels safely. Many times diet is more effective than medication in controlling diabetes - all without side effects or increased risk of death.

I ask that the NIH publicly retract the above statement. It is misleading the public.

I also request that the NIH acknowledge the existing science and fund more research by the experts who have experience with carbohydrate restriction as a means of treatment for diabetes.

For more info, or to help people with diabetes, please e-mail info@nmsociety.org .

Thank you.




I added my comment:

In my preventive cardiology practice, I have been employing strict carbohydrate restriction in both diabetics and non-diabetics. This results in dramatic improvement in lipids and lipoprotein abnormalities, substantial weight loss, and improved insulin sensitivity. This experience has been entirely different from the heart disease-causing and diabetes-causing low-fat diets that I used for years.

I have a substantial number of diabetics who have been to reduce their reliance on prescription medication for diabetes or even eliminate them. In my experience, the power of carbohydrate-restricted diets is profound.

However, better clinical data to further validate this approach is needed, particularly as diabetes and pre-diabetes is surging in prevalence. I ask that more funding to further explore and validate this research be made available if we are to have greater success on a broader basis.

Wheat withdrawal

It happens in the hospital every so often: A clean-cut, law-abiding person is hospitalized for, say, pneumonia, kidney stones, knee surgery, etc.

Everything's fine until . . . they're running down the hospital hallway stark naked, screaming about snakes on the wall, accusing nurses of trying to kill him, all while yanking out IV's and monitor patches.

It's called alcohol withdrawal. Alcohol withdrawal can range from tremulousness and sweatiness, all the way to delirium tremens, the full-blown form that leads to disorientation, seizures, fever, even death. Withdrawal can also be associated with a number of chronically used agents, such as sedatives/sleeping pills, pain medication/opiates, among others.

How about wheat?

I wouldn't have believed it, but after witnessing this effect countless times, I am convinced there is such a phenomenon: Wheat withdrawal.

You'll recognize it in someone who previously ate bread and other wheat flour-containing products freely, then eliminates them. This is followed by extreme cravings, usually for bread, cookies, or cake; profound fatigue; shakiness; mental fogginess; blue moods. The syndrome can last for up to one week.

Then, bam! Sufferers of wheat withdrawal report mental clarity superior to their wheat-crazed days, improved energy, decreased appetite and cravings, heightened mood, and, of course, fantastic drops in weight.

Why would removal of wheat from the diet trigger a withdrawal phenomenon? I can only speculate, but I believe that at least part of this response is due to a physical conversion from a glycogen (sugar)-burning metabolism to that of a fatty acid (fat mobilizing) metabolism. People who lived in the up-and-down cycle of craving and eating wheat constantly fed the sugar furnace for years and are enzymatically impaired in fat burning; they've been growing fat stores. Eliminating wheat deprives the body of this easy source of glycogen, forcing it to mobilize fatty acids in the fatty tissues. Sluggish at first, people feel fatigue, mental fogginess, etc. Once the enzymatic capacity for fat mobilization revs up, then these feelings dissipate.

Could it also relate to the opioid sequences apparently present in wheat? I wasn't even aware of this fact until a reader of The Heart Scan Blog, Anne, left this comment:

Wheat protein contains a number of opiod peptides which can be released during digestion. Some of these are thought to affect the central and peripheral nervous systems.

When I gave up gluten, I felt much worse for a few days. This is a very common reaction in those who stop eating gluten cold turkey.


Dr. BG provides a fascinating commentary on the addictive/opioid aspect of wheat addictions in her Animal Pharm Blog.

Whatever the mechanism, I believe it is a real phenomenon. It can, at times, be so overwhelming that about 20% of people who try to eliminate wheat find they are simply unable to do it without being incapacitated. Of course, that might be a lesson in itself: If withdrawal is so profound, it hints that there must be something very peculiar going on in the first place.

The Big Squeeze

Some colleagues of mine brought this scary phenomenon to my attention last evening.

As insurance and Medicare reimbursement to doctors and hospitals fall (Medicare is enacting a series of substantial cuts, which will be followed by the private health insurers), you would expect the use of hospital procedures to drop. Makes sense, right? Less money paid per procedure, less incentive to do them.

Unfortunately, that's not how it's playing out in the real world. Your neighborhood interventional cardiologist or cardiothoracic surgeon is accustomed to a level of income and lifestyle. That lifestyle is now threatened by shrinking reimbursement. True to the Law of Unintended Consequences, rather than reducing use of procedures, diminishing procedural fees are prompting a good number of practitioners to do more.

In other words, if each heart catheterization pays less, why not do more of them, along with more stents, pacemakers, defibrillators, and the like? If four heart catheterizations per day pays less, why not do five to make up the difference?

Voila! Income protected. Of course, it comes at the cost of more work. But I will give one thing to my colleageus: They are a generally hard-working bunch who rarely balk at 12-16 hours days in the hospital.

How do you do more procedures? Easy. Just lower the bar on who to do a procedure on. Use more aggressive criteria for pacemaker implantation. Interpret the always-fuzzy nuclear stress tests weighed more towards abnormal. Use scare tactics: "You never know--that chest pain could be the last warning you're going to have!" Because the criteria for performing procedures is "soft" in the real world, it is easy to bend the criteria any way you want.

It's too early to measure the full impact of this unintended consequence of reduced reimbursement. But don't allow yourself to become a casualty in the reimbursement war. Remain vigilant. Recognize that, despite the fuzziness at the edges, there are still rational reasons for performing heart procedures. Always be armed with information and the right questions. Never submit unquestioningly or without satisfactory answers to your questions.

Tim Russert's heart scan score 210. . .in 1998

Despite the media blathering over how Mr. Russert's tragic death from heart attack could not have been predicted, it turns out that he had undergone a heart scan several years ago.

A New York Times article, A Search for Answers in Russert’s Death, reported:

Given the great strides that have been made in preventing and treating heart disease, what explains Tim Russert’s sudden death last week at 58 from a heart attack?

The answer, at least in part, is that although doctors knew that Mr. Russert, the longtime moderator of “Meet the Press” on NBC, had coronary artery disease and were treating him for it, they did not realize how severe the disease was because he did not have chest pain or other telltale symptoms that would have justified the kind of invasive tests needed to make a definitive diagnosis. In that sense, his case was sadly typical: more than 50 percent of all men who die of coronary heart disease have no previous symptoms, the American Heart Association says.

It is not clear whether Mr. Russert’s death could have been prevented. He was doing nearly all he could to lower his risk. He took blood pressure pills and a statin drug to control his cholesterol, he worked out every day on an exercise bike, and he was trying to lose weight, his doctors said on Monday. And still it was not enough.

“What is surprising,” Dr. Newman said, “is that the severity of the anatomical findings would not be predicted from his clinical situation, the absence of symptoms and his performing at a very high level of exercise.”


Buried deeper in this article, the fact that Mr. Russert had a heart scan score of 210 in 1998 is revealed.

That bit of information is damning. Readers of The Heart Scan Blog know that heart scan scores are expected to grow at a rate of 30% per year. This would put Mr. Russert's heart scan score at 2895 in 2008. But the two doctors providing care for Mr. Russert were advising the conventional treatments: prescribing cholesterol drugs, blood pressure medication, managing blood sugar, and doing periodic stress tests.

Conventional efforts usually slow the progression of heart scan scores to 14-24% per year. Let's assume the rate of increase was only 14% per year. That would put Mr. Russert's 2008 score at 779.

A simple calculation from known information in 1998 clearly, obviously, and inarguably predicted his death. Recall that heart scan scores of 1000 or greater are associated with annual--ANNUAL--risk for heart attack and death of 20-25% if no preventive action is taken. The meager prevention efforts taken by Mr. Russert's doctors did indeed reduce risk modestly, but it did not eliminate risk.

We know that growing plaque is active plaque. Active plaque means rupture-prone plaque. Rupture prone plaque means continuing risk for heart attack and death. Heart attack and death means the approach used in Mr. Russert was a miserable failure.

While the press blathers on about how heart disease is a tragedy, as Mr. Russert's doctors squirm under the fear of criticism, the answers have been right here all alone. It sometimes takes a reminder like Mr. Russert's tragic passing to remind us that tracking plaque is a enormously useful, potentially lifesaving approach to coronary heart disease.

Who needs to go next? Matt Lauer, Oprah, Jay Leno, some other media personality? Someone close to you? Can this all happen right beneath the nose of your doctor, even your cardiologist?

I don't need to remind readers of The Heart Scan Blog that heart disease is 1) measurable, 2) trackable, 3) predictable. Mr. Russert's future was clear as long ago as 1998. Every year that passed, his future became clearer and clearer, yet his doctors fumbled miserably.

Another failure of conventional cardiac care


Though Tim Russert was widely known and respected for his political commentary, he will likely be better remembered as an example of the gross shortcomings of the conventional approach to heart disease.

Let's face it:

Standard heart disease prevention efforts are a miserable failure.

A Track Your Plaque member brought this interview of Mr. Russert's doctor to my attention.

It appears that his doctor did all the correct conventional things. You know what became of it. In the eyes of the public and of any attorney, or even of my colleagues, no wrong was committed. The blame does not lie with Mr. Russert's hapless doctor. The blame lies on the system that endorses procedures, prescription medications, the blind adherence to dogma dictated by the pharmaceutical industry and FDA, along with a prevailing philosophy of preferring the management of catastrophes to preventing them. Dr. Newman's idea of a solution: Making an automatic defibrillator (AED) more widely available (!!!).

How long does this sort of idiocy have to go on? How many people have to die before the system uses the tools that are already available, tools that could have prevented this tragedy and many more like it?

If you and your doctor subscribe to the program that the unfortunate Mr. Russert was prescribed and the brainwashing, unthinking nonsense that his doctor follows, you are a fool. Shame on you. You therefore likely subscribe to the same variety of marketing BS that issues from food manufacturers about Cheerios, whole grains, and low-fat diets.

Get with the program. Sadly, Mr. Russert is not the first, he's not the last. The tragedies of conventional advice that line the pockets of drug and food manufacturers number in the millions. We're not talking about some obscure, rare disease. We're talking about the number one cause of death in both males and females nationwide.

I deeply wish this message could have reached Mr. Russert before his untimely death. We could all look forward to another Sunday morning with his usual incisive, unforgiving probing of the day's political figures.

Tribute to Tim Russert

The sudden passing of news giant, Tim Russert, yesterday of sudden cardiac death struck a blow to American consciousness.

Perhaps his hard-hitting interviewing style, while making guests squirm, made him seem invincible. But, of course, none of us is invincible. We are all vulnerable to this disease.

We should not allow Mr. Russert's tragic death to occur without taking some lessons. The media have already resorted to interviewing prominent doctors for their opinion.


Douglas Zipes, M.D., former President of the American College of Cardiology,was quoted in the media:

"An automated external defibrillator (AED) could have been a life-saver. AEDs should be as common as fire extinguishers."

This is typical sleight-of-hand, medicine-is-too-complex-for-the-public-to-understand sort of rhetoric that is surely to issue from the conventionally-thinking medical people and the press. Instead, let's cut the BS and learn the real lessons from Mr. Russert's needless death.

It is virtually certain that:

--Mr. Russert ruptured an existing coronary atherosclerotic plaque, prompting rhythm instability, or ventricular fibrillation.

--Making automatic external defibrillators (AED) available might have Band-Aided the ventricular fibrillation, but it would not have stopped the heart attack that triggered it.

--Though full details of Mr. Russert's health program have not been made available, it is quite likely that he was prescribed the usual half-witted and barely effective panoply of "prevention": aspirin, statin drug, anti-hypertensive medication. Readers of The Heart Scan Blog and members of Track Your Plaque know that this conventional approach is as effective as aspirin for a fractured hip.

--It is highly unlikely that all causes of Mr. Russert's heart disease had been identified--did he have small LDL (it's certain he did, given his body habitus of generous tummy), Lp(a), low HDL, pre-diabetic patterns, inflammatory abnormalities, vitamin D deficiency, etc.? You can be sure little or none of this had been addressed. Was he even taking simple fish oil that reduces the likelihood of sudden cardiac death by 45%?

--Far more could have been done to have prevented Mr. Russert's needless death. And I don't mean the idiocy of making AED's available in office buildings. I'm talking about preventing the rupture of atherosclerotic plaque in the first place.

Far more can be done to prevent future similar deaths among all of us.

Our jobs are to use the tragic death of Mr. Russert to help those around us learn that heart disease is identifiable and preventable. Though Mr. Russert did not stand for BS in his political commentary, he sadly probably received it in his health advice. Don't let this happen to you or those around you.

Why do skinny people get heart disease?

There's no doubt about it: The majority of people with heart disease are overweight. They may not be grotesquely overweight, just a few pounds over. But weight plays a crucial role in activating numerous factors that heighten risk for heart disease.

Excess weight reduces HDL cholesterol, raises triglycerides, increases small LDL (enormously), fans the fires of inflammatory responses (CRP, IL-6, TNF-alpha, etc.) raises blood pressure, increases resistance to insulin and raises blood sugar. Overweight people tend to be less physically active, may develop diseases of obesity like sleep apnea, and on and on. You've heard this all before.

But why do slender people develop heart disease? If we can't blame weight, what is to blame? By slender, I mean body mass index (BMI) of <25. (Yes, I know there are other ways, better ways, to gauge healthy weight. But, for simplicity, I'll use BMI.) Let's put aside the two obvious causes of heart disease, cigarette smoking and Type I diabetes. (I'd be shocked if any cigarette smokers read this blog.)

Slender people develop heart disease because:

1) They have lipoprotein(a)--The big, big neglected risk factor. In fact, the Lp(a) genotype is, in my casual observation, associated with a slender phenotype (genotypic expression). The prototypical example that makes headlines is the marathon runner--slender and superbly fit, but develops heart disease anyway. People wax on about the uncertainties of exercise and fitness when they hear about Jim Fixx and Alberto Salazar. But one factor would explain it all: Lp(a).

2) The murky category of the normal weight obesity. These people are generally recognizable by their flaccid tummies despite falling into a favorable BMI <25. Small LDL is the standout red flag in these people.

3) They were previously overweight but lost it.

4) They were former smokers.

5) Vitamin D deficiency--Deficiency of vitamin D is important for everyone's health. But there appears to be some people for whom it is the dominant risk. I believe that one of our great Track Your Plaque success stories, Neal, falls into this group. Some people who are vitamin D deficient develop colon cancer, others develop diabetes, others develop osteoporosis or multiple sclerosis, while others develop coronary heart disease and plaque. The likely reason for the varied expression is variation in vitamin D receptor genotypes (VDR genotypes).

6) The murkiest of all: Hypertension genotypic variants. This is a poorly sorted-out category, and one principally based on my observations along with scattered observations in such things as variations in the angiotensin converting enzyme genotypes. But I am convinced that there is a small percentage of slender people who show variation in some genetic type that predisposes to hypertension and heart disease. They also show a propensity towards enlargement of the thoracic aorta. This group is also among the most difficult to control in the Track Your Plaque approach, i.e., they have difficulty slowing or stopping the growth of heart scan scores. While blood pressure control in this group is important, it does not seem to remove the excess source of risk.

So, yes, being slender does put you into a lower risk for heart disease category. But it does not mean you are immune.

You can also be an overweight person who still harbors some of the features of the slender--you're an overweight slender person. The above list can still therefore apply.

Cardiology Confidential


Okay, so it's a shameless knockoff of chef Anthony Bourdain's titillating Kitchen Confidential.

But the confidences that I've heard whispered in the corridors of health involve something more provocative than how your food was prepared. Any service for humans performed by other humans is subject to the idiosyncrasies and weaknesses of human behavior. That's just life.

In healthcare for your heart, the consequences can be more profound than eating three day old fish on Monday's dinner menu.

Over my 15 years practicing cardiology in a variety of settings in three different cities, I've witnessed just about everything from shocking to sublime. Some of it speaks to the extraordinary commitment of people in healthcare, the unexpected courage people show in the midst of illness, the devotion of family in difficult times. It can also speak of mewling, sobbing carryings-on over the most minor conditions, the meanness that emerges when people are frightened, the vultures circling just waiting for Grandpa to kick the bucket and leave his will declaring the spoils.

For the most part, my cardiology colleagues are a hard-working bunch committed to . . . Uh oh. I was going to say "Saving lives, preserving health." But that's not true. Once upon a time, it was true for many of my colleagues, often revealed over $2-a-pitcher beer-softened, "we're going to save people" conversations in medical school. Ahhh, medical school. I remember walking along the street alongside my medical school in St. Louis, bursting with pride and a sense of purpose.

But, for many of us, something sours our purpose through the years. Maybe it's the smell of money, maybe it's the series of distasteful experiences that show that healthcare providers are, in the midst of health crises, the innocent recipients of anger, frustration, disappointment.

Whatever the genesis, the stage is set for an imperfect scenario that pits healthcare provider against patient in a less-than-perfect system.

This would read as a mindless rant if it wasn't based on such pervasive and pravalent truths, tales of the flawed deliverers of healthcare driven by motives less lofty than "saving people."

Take Dr. S, a doctor who performs a large number of procedures on patients. I'm told he is very capable. He manages an extraordinary amount of heart work--in between jail time for wife beating and Medicare fraud.

Or Dr. C, well-known in the region for his procedural talents, also. Usually acerbic and freely-swearing, he opens up engagingly when drinking--which is most of the time. Paradoxically, as is true for some serious drinkers, he works more effectively while intoxicated.

Or Dr. ST, who proudly admitted to me one evening over dinner that he has accepted 6-figure payments from medical device companies on a number of occasions to use their products.

Or the manic ups and downs of Dr. J, who refers just about every patient he sees for emergency bypass surgery when in his down phase, mangles coronary arteries in daring angioplasties during his up phase.

How about 310-lb Dr. P, who hounds her patients about indulgent lifestyles? That would be excusable as innocent lack of self-insight if it weren't for her propensity to use heart procedures on patients as punishment. "I have no choice but to take you to the hospital."

Dr. M. manages to maintain the appearance of straight-and-narrow during the day, all the way to attending church twice a week with his children. His daytime persona effectively covers up his frequent visits to prostitutes.


We are ALL flawed. My colleagues are no different. But some circumstances cultivate the flaws, fertilize corruptibility, reward it. Such has become the state of affairs in healthcare for heart disease. Why? Is it the excessive potential for money-making that existed until recently? Is there something about the save-the-day mentality of heart disease that attracts imperfect personalities looking for the adrenaline-charged thrill but morphs over time into near-psychopathic lives?

It's not the end of the world. The fact that my colleagues' behavior has reached such extravagant lows signals a bottom: things are about to change.

In the meantime, let me tell you a few more secrets . . .
