Brainwashed!

At a social gathering this weekend, as we humans like to do, someone asked me what I did for a living. I told him I was a cardiologist.

"What hospital do you work at?" he asked.

This is invariably the response I get whenever I tell people what I do. I wouldn't make much of it except that it happens just about every time.

This indicates to me just how successful hospitals, my colleagues, cardiac device manufacturers, and others supporting the status quo in heart care, have been in persuading us that the place for heart disease is the hospital--period.

Tense families, drama, high-tech...It all takes place in the hospital.

Yet the people destined to be the fodder for hospital heart care are presently well, mostly unaware of what the future holds. Also unaware that heart disease is readily, easily, inexpensively, and accurately identifiable. Ask anyone in the Track Your Plaque program who's had a CT heart scan.

We all need to rid ourselves of the idea that the hospital is the place for heart disease. If the coronary plaque behind heart attack is easy to detect and controllable, there's little or no need for the hospital for the vast majority of us.

In the majority of instances of coronary disease, the hospital should be the place for the non-compliant and the ill-informed, and not for those of us sufficiently motivated to know and do better. The formula is simple: 1) Quantify plaque with a CT heart scan, 2) Identify the causes, then 3) Correct the causes.

The Fanatic Cook: A fabulous Blog about food and nutrition

I came across this Blog authored by a nutritionist when it was highlighted on Blogger as an interesting site:

The Fanatic Cook at http://fanaticcook.blogspot.com/

I was thoroughly impressed with the insightful and entertaining commentary. I'd highly recommend this site to you for reading on nutrition. In particular, her coenzyme Q10 column was exceptionally well written and clear.(http://fanaticcook.blogspot.com/2005/02/statins-and-not-well-publicized-side.html)

Also read her column, Super NonFoods at http://fanaticcook.blogspot.com/2005/07/super-nonfoods.html.

There's also oodles of recipes, all for the taking.

Eggs: Good, bad, or indifferent?

Eggs have been in the center of the cholesterol controversy almost from the very start.

The traditional argument against eggs went that eggs, high in cholesterol (210-275 mg per egg)and with some saturated fat (1.5-2.5 grams per egg), raised blood cholesterol (and LDL). Out went the daily fried, scrambled, poached eggs that many Americans indulged in most mornings. (We replaced it with more breakfast cereals and other carbohydrate conveniences, then got enormously overweight.)





A large Harvard epidemiologic study in 1999 called this observation into question. They tracked the fate of 117,000 thousand people and then compared the rate of heart attack, death, and other cardiovascular events among various people correlated to the "dose" of eggs they ate. Egg intake varied from none to 7 or more per week. Lo and behold, people who ate more eggs appeared to not suffer more events.

This study, large and well-conducted by an internationally respected group of investigators, seem to reopen the gates for more egg consumption, though most Americans still consume eggs cautiously.

Deeper down in this study, however, was another observation: People with diabetes who ate 1 egg per day had double the risk of heart attack. Because this study was observational, no specific conclusion as to why could be drawn.

A new study conducted by a Brazilian group may shed some light. Healthy (non-diabetic) men were fed an emulsion of several eggs. Inclusion of plentiful yolks caused a dramatic slowing of fat clearance from the blood. Specifically, "chylomicron remnants" were abnormally persistent in the blood. Chylomicron remnants are potent causes of coronary plaque. (Chylomicron remnants can be measured fairly well by intermediate-density lipoprotein and VLDL by NMR, or IDL by VAP.)

Diabetics are know to have substantial disorders of after-meal fat clearance, including an excess of chylomicron remnants. Could the Brazilian observation be the explanation for the increased event rate in diabetics in the Harvard study? Interesting to speculate.

We continue to tell our patients that eating eggs in moderation is probably safe. After all, there are good things in eggs: the high protein in the egg white, lecithin in the yolk. It is the yolk's contents that are in question, not the white. Thus, you and I can eat all the egg whites (e.g., Egg Beaters) we want. It's the safety of yolks that are uncertain.

The abnormal after-eating effect suggested by the Brazilians opens up some very interesting questions and confirms that we should still be cautious in our intake of egg yolks. One yolk per day is clearly too much. What is safe? The exisitng information would suggest that, if you have diabetes, pre-diabetes, or a postprandial disorder (IDL, VLDL), you should minimize your egg yolk use, perhaps no more than 3 or so per week, preferably not all at one but spaced out to avoid the after-eating effect.

Others without postprandial disorders may safely eat more, perhaps 5 per week, but also not all at one but spaced out.

Track Your Plaque Members: Be sure to read our upcoming Special Report on Postprandial Disorders. It contains lots of info on what this important pattern is all about. Postprandial disorders are largely unexplored territory that hold great promise for tools to inhibit coronary plaque growth and drop your heart scan score. The Brazilian study is just one of many future studies that are likely to be released in future about this very fascinating area.

Diabetes is Track Your Plaque's Kryptonite!


If there's one thing I truly fear from a heart scan score reduction/coronary plaque regression standpoint, it's diabetes.

I saw a graphic illustration of this today. Roy came into the office after his 2nd heart scan. His first scan 14 months ago showed a score of 162. Roy started out weighing well over 300 lbs and with newly-diagnosed adult diabetes.

Roy put extraordinary effort into his program. He lost nearly 70 lbs by walking; cutting processed carbohydrates, greasy foods, and slashing overall calories. His lipoproteins, disastrous in the beginning, were falling into line, though HDL was still lagging in the low 40s, as Roy remains around 60 lbs overweight, even after the initial 70 lb loss.

Unfortunately, despite the huge loss in weight, Roy remains diabetic. On a drug called Actos, which enhances sensitivity to insulin, along with vitamin D to also enhance insulin response, his blood sugars remained in the overtly diabetic range.

Roy's repeat heart scan showed a score of 482--a tripling of his original score.

Obviously, major changes in Roy's program are going to be required to keep this rate of growth from continuing. But I tell Roy's story to illustrate the frightening power of diabetes to trigger coronary plaque growth.

Like Kryptonite to Superman (remember George Reeves crumbling and falling to his knees when the bad guys got a hold of some?), diabetes is the one thing I fear greatly when it comes to reducing your heart scan score. As you see with Roy's case, diabetes can be responsible for explosive plaque growth, more than anything else I know.

The best protection from diabetes is to never get it in the first place. (See my earlier Blog, "Diabetes is a choice you make".)

Boy, was I wrong!

Around 10 years ago, I was talking to a balloon and stent manufacturer's representative, who was raving about some new device that was due for release to the market. Back then, the sky seemed the limit to cardiac device manufacturers, who were falling over themselves scrambling to design and market the next new device.

The angioplasty market then had ballooned (no pun intended) from nothing to a multi-billion dollar industry. Stents were just getting underway but clearly had potential for being at least as large.

But this was a time when preventive therapies were also beginning to get quite powerful. We had just gotten started doing CT heart scans and were excited about the possibilities, statin drugs were gaining evidence through clinical trials, and the power of many nutritional supplements was finally achieving validation. We were even learning the error of our prior low-fat ways.

So I broadly pronounced to the enthusiastic product representative, "In 10 years, balloons, angioplasty, and stents will occupy this little corner of cardiac care because prevention will have become so powerful. We won't talk about heart procedures. We'll talk about coronary plaque regression!"

I even advised the representative that he should consider a career change in anticipation of the coming wave of preventive strategies.

Was I ever wrong. Despite the power of heart disease prevention--which is indeed true--cardiac device and procedure technology has boomed, both in popularity as well as in revenue success. Device manufacturing and sales are hugely successful. Implanting devices into people is a hugely profitable enterprise.

Since my ill-timed comments to the salesman, Boston Scientific, a major manufacturer of stents and other cardiac devices, reported revenues of $6.2 billiondollars in 2005, a 12% increase over the prior year. Medtronic reported 2005 revenues of $11.3 billion, growing at 15% per year. Clearly, cardiac procedures are still quite popular--and profitable.

My timing was off, but not for long. The huge crest of change in preventive therapies is upon us. That's the premise behind the Track Your Plaque concept: heart disease prevention can't be found in a hospital, is not supported by cardiac device manufacturers, and is not being advocated by most cardiologists or primary care physicians. Yet the tools are getting better and better every day.

Those of you who succeed in halting or reducing your heart scan score are extremely unlikely to add to Boston Scientific's or Medtronic's revenues. Help me spread the word.

Don't forget how dangerous heart disease can be

Sometimes it's easy to get smug when coronary plaque is a reversible process.

When you see people day in, day out, week in, week out, drop their heart scan scores, reversing what could be a dangerous disease, you can sometimes lose sight of just how dangerous coronary disease can be.

Whether I like it or not, I maintain a reasonably active role in hospitals out of necessity. I do need their services occasionally for people with advanced heart disease when I meet them (when regression is not the initial conversation for safety reasons), or valve disease is diagnosed, or someone shows up with congenital or heart muscle diseases. In other words, although we focus on coronary issues, there's more to heart disease than just coronary disease.

This unfortunate case just served to remind me how powerful coronary disease can be. Elizabeth, an active 67-year old, finally came to the hospital after suffering 6 months of chest pain and increasing breathlessness. She hated hospitals and hadn't seen a doctor in 30 years since she was successfully treated for cancer.

In those 30 years, she'd been quite active with family and a small business. But she also smoked 2 packs of cigarettes most of those years.

After she was admitted to the hospital, it became clear that Elizabeth had experienced one, if not several, heart attacks along the way. The entire front 2/3 of her heart was non-functional. If that wasn't bad enough, two of her heart valves were severely diseased and dysfunctional: Her aortic valve barely opened (aortic valve "stenosis", or stiffness) and the mitral valve leaked severely (mitral valve "insufficiency", or leakiness). All of this was confirmed with conventional testing in the hospital, including a heart catheterization.

Elizabeth ended up in emergency surgery--very unusual, by the way, for valve surgery of the sort she had--but died in the first few hours after her procedure. Her heart had simply been too damaged from her heart attacks, and the extraordinary stress of surgery that included two valves was too much. She died on the ventilator.

Coronary disease is a very serious matter. When I see cases like Elizabeth, it boosts my commitment to tell everyone that heart disease--when identified early enough--is a controllable, preventable, even reversible process. For poor Elizabeth, she was much too far down the path of severe, irreversible disease that control or reversal was simply not an option. She was in imminent danger of dying even upon arrival.

It's exciting yet sometimes frightening to know what you have in your hands: The means to control this monster called coronary disease. Use it wisely. But don't lose sight of what it can do it you permit it to grow, fester, and explode.

How many ways can you disguise sugar?

I came across this shockingly silly report on AOL, who obtained their info courtesy Health Magazine:

The Best New Healthy Foods for Busy People
from Health


The foods on their list:

Kettle Brand Bakes Hickory Honey BBQ--the healthy claim is based on the lack of trans-fatty acids and low-fat.










Post Healthy Classics Raisin Bran Cereal Bars, Cranberry--Likewise, low-fat, sweet, and addictive means healthy to these people.




Amy’s Mediterranean Pizza With Cornmeal Crust --Please!!



Horizon Organic Colby Cheese Sticks --Because it's made by cattle without use of growth hormone or antibiotics, they declare this healthy. I guess we can ignore the saturated fat content and high total fat content.

100% Whole Grain Chips Ahoy! Cookies --You mean we can add the bran back to wheat products and make it healthy?!


This kind of mass-market marketing trickery leaves me incredulous. Don't believe it for a moment. This is typical of the food industry: Take one aspect of nutrition that is truly healthy, such as high-fiber, or low-fat, or organic. Then add undesirable, unhealthy ingredients. The current fad is to add lots of sugar and or sugar-equivalents (usually flour and other wheat products). Because there's one healthy ingredient, they'll call the end-product healthy, too.

If you want to see what health looks like if you indulge in "healthy" products like this, just look up and down the grocery aisles at your neighborhood grocery store. You're likely to see the results: Gross obesity, diabetes, and arthritis.

You won't, of course, see the huge acceleration of growth in coronary plaque, but it's there, ticking away.

To remind us what ideal body weight is: Watch an old movie!

Jack was skeptical. At 273 lbs, 5 ft 11 inches, he felt that he was "just right".

"I feel fine. I don't see why you think I should lose weight," he declared. "In fact, when I lost 25 lbs a couple of years ago, everyone said I was too skinny!"

I showed Jack why: He had an HDL of 35 mg/dl, small LDL (over 90% of all LDL particles), an elevated blood sugar of 123 mg/dl (diabetes is officially 126 mg/dl or greater), high blood pressure, and increased inflammation (C-reactive protein). These were all manifestations that his body weight was too much for it to handle.




So I told Jack that we've all forgotten what ideal weight should look like. Our perception of "normal" has been so utterly and dramatically distorted by the appearance of our friends, family, co-workers, and other people around us that we've all lost a sense of what a desirable weight for health should be.




So I suggested to Jack that, if he wanted to rememember what ideal weight is and what people are supposed to look like, just watch old movies.

Old movies, like the 1942 production of Casablanca, or the 1952 production of Singin' in the Rain, show the body build that was prevalent in those days. Look at Humphrey Bogart or Gene Kelly--men with average builds, weighing 140-160 lbs--that's how humans were meant to look.

A report this morning on the Today Show showed the "after" photos of several people following bariatric (weight reduction) surgery. The "after" pictures, from the perspective of ideal weight and ideal health, remain hugely overweight.

We need to readjust our perceptions of weight. The average woman in the U.S. now weighs 172 lbs(!!!). Don't confuse average with desirable.

Diabetes is a choice you make

Tim had heart disease identified as a young man. He had his first heart attack followed by a quadruple bypass surgery at age 38. Recurrent anginal chest pain and another small heart attack led to several stents over three procedures in the first four years after bypass.

Tim finally came to us, interested in improving his prevention program. You name it, he had it: small LDL, low HDL (28 mg/dl), lipoprotein(a), etc. The problem was that Tim was also clearly pre-diabetic. At 5 ft 10 inches, he weighed 272 lbs--easily 80 or more pounds overweight.

Tim was willing to make the medication and nutritional supplement changes to gain control over his seeminglly relentless disease. He even turned up his exercise program and lost 28 lbs in the beginning. But as time passed and no symptoms recurred, he became lax.

Tim regained all the weight he'd lost and some more. Now Tim was diabetic.

"I don't get it. I eat good foods that shouldn't raise my insulin. I almost never eat sweets."

I stressed to Tim that diabetes and pre-diabetes, while provoked acutely by sugar-equivalent foods (wheat products, breads, breakfast cereals, crackers, etc.), is caused chronically by excess weight. If Tim wants to regain control over his heart disease, he needed to lost the weight.

Unlike, say, leukemia, an unfortunate disease that has little to do with lifestyle choices, diabetes is a choice you make over 90% of the time. In other words, if you become diabetic (adult variety, not children's variety) as an adult, that's because you've chosen to follow that path. You've neglected physical activity, or indulged in too many calories or poor food choices, or simply allowed weight to balloon out of control.

But diabetes is also a path most people can choose not to take. And it is a painfully common choice: Nearly two-thirds of the adults in my office have patterns of pre-diabetes or diabetes when I first meet them.

Let me stress this: For the vast majority of adults, diabetes is a choice, not an inevitability.

I'll call the doctor when I feel bad!

Max just had his heart scan. He sat down with the x-ray technologist at the work console while she pointed out the white areas in his coronary arteries that represented plaque.

"It looks like you're going to have a fairly high score," the technologist commented. "The final report will be available after one of our cardiologists reviews your images."

Max shrugged. "Well, I don't feel anything. I'm always running around with work, with my kids, stuff like that. That's better than any stress test. I guess I'll worry about it if it starts to bother me."


You'd be surprised how common this view remains: If it's not bothering you, then just forget about it. It's easy to do, since you have no symptoms, nothing to impair your physical activities. But what are the potential consequences of ignoring your heart scan? Here's a few:

--Prevention and plaque reversal efforts are most effective the earlier you start. From a heart scan score viewpoint, the lower your starting score, the easier it is to gain control over it. More people will succeed in reducing their score when the starting score is lower.

--The role of prevention of heart disease instantly crystallizes when you know your score. Your LDL cholesterol of 142 mg/dl or HDL of 41 mg/dl no longer seem like just numbers of borderline signficance. Instead, they become useful tools to gain control over plaque. They cast your numbers in a new and clear light.

--Knowing your heart scan score today gives you a basis for comparison in future. Your score of, say 250, today, can be 220 in one year. Without your preventive efforts, it will be 30% higher: 325. That's a big difference!

--Sudden death or heart attack--can occur in up to 35-40% of people with hidden heart disease--without warning.

Don't even bother getting a heart scan if you're going to ignore it. I've said it before and I'll say it again: A heart scan is the most important health test you can get--but only if you do something about it.

Dr. Cannell comments on vitamin D lab tests

As always, Dr. John Cannell of The Vitamin D Council continues to teach us new lessons about vitamin D.

Apparently, Dr. Cannell is swamped with the attention that vitamin D is drawing, largely due to his efforts to publicize the enormous deficiency of Americans and his great talent for articulating the science. The most current newsletter, while a bit haphazard, makes some excellent new points that I reprint here.

(I did not reprint his conversation about "any form of vitamin D" being acceptable. My experience differs: In nearly 1000 patients who have taken vitamin D supplements, my experience is that most tablet forms are inconsistently absorbed, sometimes not absorbed at all. I therefore advocate only use of gelcaps or liquids. I'm told by members of Track Your Plaque, however, that they are witnessing reliable increases in blood levels of vitamin D by taking the powdered form of Bio Tech Pharmacal's product.)


Does it matter what reference lab my doctor uses?

Yes, it might make a huge difference. A number of methods exist to measure 25(OH)D in commercial labs. The two most common are mass spectrometry and a chemiluminescence method, LIAISON. The first, mass spectrometry, is highly accurate in the hands of experienced technicians given enough time to do the test properly. However, in the hands of a normally trained technician at a commercial reference lab overwhelmed with 25(OH)D tests, it may give falsely elevated readings, that is, it tells you are OK when in fact you are vitamin D deficient. The second method, chemiluminescence, LIAISON, was recently developed and is the most accurate of the screening, high throughput, methods; LabCorp uses it. Quest Diagnostics reference lab uses mass spec. Again, both Quest and LabCorp are overwhelmed by 25(OH)D requests. The problem is that the faster the technicians do the mass spec test, the more inaccurate it is likely to be. If your 25(OH)D blood test says "Quest Diagnostics" on the top, do not believe you have an adequate level (> 50 ng/ml). You may or may not; the test may be falsely elevated. Let me give you an example. A doctor at my hospital had Quest Diagnostics do a 25(OH)D. It came back as 99 ng/ml of ergocalciferol. He is not taking ergocalciferol (D2), he has never taken ergocalciferol, only cholecalciferol, and he is not taking enough to get a level of 99 ng/ml, 50 ng/ml at the most. His email to Dr. Brett Holmquist at Quest about why Quest identified a substance he was not taking went unanswered other than to say "any friend of Dr. Cannell's is a friend of ours."

Long story short: if your lab report says "LabCorp" on the top, it is probably accurate; if it says Quest Diagnostic, it may be falsely elevated. While LabCorp has also been overwhelmed with 25(OH)D requests, the LIAISON method they use is relatively easy to do and does not rely on technician skill as much as the mass spec methods do. I'm not saying this because I'm a consultant for DiaSorin, who makes LIAISON, I'm saying it because it is true. If you don't believe me, get Quest to make me an offer to be their consultant at 10 times what DiaSorin is supposed to be paying me ($10,000 per year) and see how fast I turn Quest down. If Quest fixes their test, I'd love to consult. The ironic thing: I've made both Quest and LabCorp lots of money via this newsletter, the website, and by repeatedly telling the press that people need to know their 25(OH)D level, which has contributed to the skyrocketing sales of 25(OH)D blood tests.

Demand for vitamin D tests soars as nutrient's potential benefits touted.

Here you can help. Find out which labs in your town use Quest Diagnostics and which use LabCorp. Have a 25(OH)D test at both labs the same day (you will have to pay for them yourself). Then send both results to the Vitamin D Council address below. If Quest Diagnostics does not fix their 25(OH)D test, the Vitamin D Council will fix it for them.



My doctor prescribed Drisdol, 50,000 IU per week. What is it?

Drisdol is a prescription of 50,000 IU tablets of ergocalciferol or D2. Ergocalciferol is not vitamin D but it is similar. It is made by irradiating ergosterol, which is found in many living things, such as yeast. D2 is not normally found in humans and most studies show it does not raise 25(OH)D levels as well as human vitamin D (cholecalciferol or D3) does. However, Drisdol is a lot better than nothing. The best thing to do, if you are vitamin D deficient, and a human, is to take human vitamin D, cholecalciferol, A.K.A. vitamin D3.



What is the ideal level of 25(OH)D?

We don't know. However, thanks to Bruce Hollis, Robert Heaney, Neil Binkley, and others, we now know the minimal acceptable level. It is 50 ng/ml. In a recent study, Heaney et al enlarged on Bruce Hollis's seminal work by analyzing five studies in which both the parent compound, cholecalciferol, and 25(OH)D levels were measured. It turn out that the body does not reliably begin storing the parent compound (cholecalciferol) in fat and muscle tissue until 25(OH)D levels get above 50 ng/ml. The average person starts to store cholecalciferol at 40 ng/ml, but at 50 ng/ml, virtually everyone begins to store it for future use. That is, at levels below 50 ng/ml, the body is usually using up the vitamin D as fast as you make it or take it, indicating chronic substrate starvation, not a good thing.

I have advanced renal failure and I'm on dialysis, how much vitamin D should I take?

The same as everyone else. Since I have told you about commercial labs ripping you off, let's add some drug companies. Patients with advanced renal failure need activated vitamin D or one of it's analogs, available by prescription. This is very important as their kidneys cannot make enough 1,25-dihydroxy-vitamin D (calcitriol) to maintain serum calcium. However, the rest of their tissues activate vitamin D just fine and when those tissues get enough, and when the kidneys get more vitamin D, the calcitriol spills out into the blood, lowering their need for prescription calcitriol or one of its analogs. The companies that make the analogs don't like that, it means reduced sales. So these companies do nothing, the scientists behind these companies say nothing, and renal failure patients die prematurely from one of the vitamin D deficiency diseases.

When I asked my doctor for a 25(OH)D blood test, he just laughed and said it was all idiotic. What can I do?

Help me unleash the dogs of war, the plaintiff attorneys. If you read about past nutritional epidemics caused by society, such as beriberi or pellagra, you will realize that education alone will take decades. Physicians successfully fought against the idea that thiamine deficiency caused beriberi for decades. However, things are different now. The agents of change in modern America, as obnoxious as they are, are plaintiff attorneys. Once the first malpractice lawsuits claiming undiagnosed and untreated vitamin D deficiency led to breast cancer, autism, heart disease, etc., get past summary judgment, and they will, and end up in front of a jury, and they will, things will change rapidly. One of the main reason physicians do what they do is fear of lawsuits. In a matter of months, arrogance and ignorance will give way to 25(OH)D tests and vitamin D supplementation.

Privileged information

In 1910, taking a person's blood pressure was considered revolutionary, a high-tech practice that was of uncertain benefit.

Dr. Harvey Cushing of Johns Hopkins Hospital in Baltimore had observed a blood pressure device while traveling in Europe, developed by Dr. Sciopione Riva-Rocci. Cushing brought this new technology back with him to the U.S. and promptly promoted its use, convinced that this insight into gauging the forcefulness of blood pressure would yield useful clinical insights.

But, in 1910, practicing physicians rejected this new technology, preferring to use their well-established and widely practiced technique of pulse palpation (feeling the pulse), skeptical that the new tool added value. Medical practice of the day was rich with descriptions of the strength and character of the pulse: pulsus parvus et tardus (the slow rising pulse of aortic valve stenosis), the dicrotic notch of aortic valve closure transmitted to the pulse, the "water-hammer" pulse of aortic valve insufficiency.

Over the next 20 years, however, the medical community finally gave way to the new technique, although only physicians were allowed to use blood pressure devices, as nurses were regarded as incapable of mastering the skills required to perform the procedure properly.

Stethoscopes were also gaining in popularity in the early 20th century, but were also the exclusive province of physicians trained in their use. Nurses were not allowed to use stethoscopes until the 1960s. Even then, nurses were not allowed to call them "stethoscopes," but "nurse-o-scopes" or "assistoscopes," and the nurses' version of the device was manufactured to look different to avoid confusion with the "real" doctor's tool.

And just half a century ago, if you wanted to look at a medical textbook, you would have to go to the library and ask for special permission. The librarian would lower her glasses and look you up and down to determine whether or not you were some kind of pervert. Only then might you be granted permission to peer into the pictures of organs and naked bodies.

Such has been the spirit of medicine for centuries: Medicine and its practices are meant to be secret, the insider knowledge of a privileged few.

Fast forward to 2008: The Information Age has overturned the rules of privileged information. Now you have access to the same information as I do, the same information available to practicing physicians. The playing field has been levelled.

Curiously, while information access has advanced at an instantaneous digital pace, attitudes in medicine continue to evolve at the traditional analog crawl. Many of my colleagues continue to be dismayed at the new public access to health information, belittle patients for excessive curiosity about their health, lament the erosion of their healthcare-directing authority. And while new concepts race ahead as we race towards a wiki-like collective growth in healthcare knowledge, physicians are still mired by their reluctance to abdicate their once-lofty positions as chief holders of secrets.

I believe that this is part of the reason why family doctors and cardiologists have been slow to adopt technologies like heart scans and self-empowering programs like Track Your Plaque: processes that take heart disease prevention away from the hands of physicians and place more control into the hands of the people.

Imagine the horror felt by physicians in 1935 of a young upstart nurse boldly trying to use a stethoscope to take a patient's blood pressure. You can imagine the internal horror now being felt as you and I dare to take control over heart disease and deny them the chance to put in four stents, three bypass grafts, then direct our future health habits.

But technology has a way of marching on. It will encounter resistance, bumps, and blind-alleys, but it will go on.

Dr. Jeffrey Dach on the Track Your Plaque program

Dr. Jeffrey Dach posted a great piece on his blog, Bioidentical Hormone Blog , about his perspective on the Track Your Plaque program.

It's worth reading even for those familiar with the program, just to see a slightly different perspective. He also included many great graphics to illustrate his points.

Also, see Dr. Dach's Heart Disease: Part 2, for some novel thoughts.

Vitamin D and programmed aging?

As we age, we lose the capacity to activate vitamin D in the skin.

Studies suggest that, between ages 20 and 70, there is a 75% reduction in the ability to activate vitamin D. The capacity of conversion from 25 (OH) vitamin D to 1,25 di(OH) vitamin D also diminishes.

From Holick, M. 2006

This would explain why 70-year olds come to the office, just back from the Caribbean sporting dark brown tans, are still deficient, often severely, in blood levels of vitamin D (25(OH) vitamin D). A tan does not equal vitamin D.

A practical way of looking at it is that anyone 40 years old or older has lost the majority of ability for vitamin D activation.

This often makes me wonder if the loss of vitamin D activating potential is nature's way to get rid of us. After all, after 40, we've pretty much had our opportunity to recreate and make our contribution to the species (at least in a primitive world in which humans evolved): we've exhausted our reproductive usefulness to the species.

Is the programmed decline of vitamin D skin activation a way to ensure that we develop diseases of senescence (aging)? The list of potential consequences of vitamin D deficiency includes: osteoporosis, poor balance and coordination, falls and fractures; cancer of the breast, bladder, colon, prostate, and blood; reductions in HDL, increases in triglycerides; increased inflammation (C-reactive protein, CRP); declining memory and mentation; coronary heart disease.

Isn't that also pretty much a list that describes aging?

A fascinating argument in support of this idea came from study from St Thomas’ Hospital and the London School of Medicine:

Higher serum vitamin D concentrations are associated with longer leukocyte telomere length in women

Telomeres are the "tails" of DNA that were formerly thought to be mistakes, just coding for nonsense. But more recent thinking has proposed that telomeres may provide a counting mechanism that shortens with aging and accelerates with stress and illness. This study suggests that both vitamin D and inflammation (CRP) impact telomere length: the lower the vitamin D, the shorter the telomere length, particularly when inflammation is greater.
















Data supporting vitamin D's effects on preventing or treating cancer, osteoporosis, lipid abnormalities, inflammation, cardiovascular disease, etc., is developing rapidly.

Now the big question: If declining vitamin D is nature's way of ensuring our decline and death, does maintaining higher vitamin D also maintain youthfulness?

I don't have an answer, but it's a really intriguing idea.

Synthroid, Armour Thyroid, and the battle for T3

In the last Heart Scan Blog post on thyroid issues, Is normal TSH too high?, the provocative findings of the the HUNT Study were discussed. The text of the study can be found at:

The association between TSH within the reference range and serum lipid concentrations in a population-based study. The HUNT Study

Hypothyroidism, or low thyroid that is signaled by high thyroid-stimulating hormone, TSH, is proving far more prevalent an issue than previously thought. While previous estimates put hypothyroidism as affecting only about 3% of younger populations, 10-20% of older populations (women more so), data like the HUNT Study suggest that, if lower and lower TSH levels (higher thyroid) are necessary for perfect heart health, then many more people stand to benefit than we used to think.

But another crucial issue in the world of hypothyroidism: Is T4 (thyroxine) enough? Or should we be supplementing T3 (triiodothyronine) along with T4?

Your friendly neighborhood primary care doctor or endocrinologist would likely argue vehemently that T4 (as Synthroid, Levoxyl, levothyroxine, and others) is adequate and not subject to the impurities and contaminants of natural thyroid extracts. They would also argue that T4 is effectively converted to T3 at the tissue level, and exogenous supplementation is unnecessary.

Others--most of all thyroid patients themselves, along with thyroid advocates like Mary Shomon and Janie Bowthorpe, along with some physicians--argue that supplementing T3 along with T4 can be very important. They argue that people feel better, have more physical energy, lose weight more effectively, and more completely resolve many of the phenomena of hypothryoidism with T3 added. There are also some data that argue the same.

Adding T3 to the mix may address the presumed poor conversion of T4 to T3 that is peculiar to some people. It may overcome the "reverse T3" phenomenon, the production of a useless look-alike T3 that occurs in some people. It may also (anecdotally) exert greater effects on some lipid/lipoprotein parameters, such as Lp(a).

My experiences adding T3 to T4 have been mixed: Some feel better, others do not. Some show objective improvements, others do not.

Nonetheless, hypothyroidism, or incompletely corrected hypothryoidism by way of inadequate T3, is an issue to consider in your plaque-control program.

More on this somewhat complex issue, along with practical solutions to consider, can be found on the Special Report to be released this week on the Track Your Plaque website.

Letter to New York Times

All right. I sent a Letter to the Editor to the New York Times. No word from them; it's no longer news.

So here is what I tried to convey.

While the authors overall did a credible job of talking to my colleagues and laying out the issues, they made the crucial and boneheaded mistake of confusing CT heart scans with CT coronary angiograms. Sadly, many people who may have been considering having a simple screening heart scan may be scared away by the confused authors, Alexn Berenson and Reed Abelson.

They do correctly point out that, while CT coronary angiograms are fascinating examples of technology and a way of visualizing coronary arteries, this test all too often is being subverted into the "let's make money from high-tech testing" medical model. It's also a test that frequently leads to the "real" test, heart catheterization, since the "time bomb" you have in your arteries might "need" a stent.

CT coronary angiograms are also virtually useless for purposes of tracking disease, since they are not longitudinally (along the length of the artery) quantitative, nor should anyone be exposed to this much radiation repeatedly.

A simple heart scan, on the hand, provides a longitudinal summation of coronary plaque volume. Radiation exposure is sufficiently low that repeated scanning can be performed for purposes of tracking . . .yes, track your plaque.

Poorly-informed reporters can do a lot of damage. As always, you and I must dig a little deeper for the truth.




Dear Editor,

Re: Weighing the Costs of a CT Scan’s Look Inside the Heart

The Times featured an article on June 29th that discussed rapidly expanding use of CT scans for the heart:
Weighing the Costs of a CT Scan’s Look Inside the Heart.

The authors, Alex Berenson and Reed Abelson, stated that CT heart scans “expose patients to large doses of radiation, equivalent to at least several hundred X-rays, creating a small but real cancer risk.”

I’d like to offer a clarification.

Though the authors discuss both CT heart scans and CT coronary angiograms, they confuse the two and use the terms interchangeably.

A heart scan is a simple screening test for coronary atherosclerotic plaque. It detects the presence of calcium in the heart’s arteries, provided as a “score.” (Because calcium occupies 20% of total plaque volume, knowing the amount of calcium tells you how much total coronary plaque is present by applying this simple proportion.) Just having a high score should not prompt heart procedures, since people undergoing simple screening heart scans are without symptoms. However, a stress test may yield some useful information.

On present-day CT devices, heart scans expose a patient to 0.4 mSv of radiation on an electron-beam, or EBT, device, and on up to 1.2 mSv on a 64-slice multi-detector, or MDCT, device, compared to 0.1 mSv during a standard chest x-ray. CT heart scans are therefore performed with about the same quantity of radiation as a mammogram done to screen women for breast cancer, or about the equivalent of four chest x-rays on an EBT scanner, up to 12 chest-xrays on a MDCT scanner.

CT coronary angiograms, while performed on the same devices as heart scans, require x-ray dye to fill the contours of the coronary arteries. It also requires up to several hundred times more radiation. While new engineering innovations are being introduced that promise to reduce this exposure, the current devices being used today do indeed require a radiation dose equivalent to 100 to 400 chest x-rays (usually in the range of 10-15 mSv), a value that equals or exceeds that obtained during a conventional heart catheterization.

While heart scans are most useful to detect and quantify plaque that can help determine the intensity of a heart disease prevention program, CT coronary angiograms are generally used as prelude to hospital procedures like catheterizations, stents and bypass surgery. That’s because they are performed to look for (or rule out) “severe” blockages.
CT heart scans and CT coronary angiography are therefore two different tests that yield two different kinds of information, and yield two entirely different levels of radiation exposure.

This confusion from a major and respected media outlet like the New York Times is unfortunate, because it could persuade millions of people who otherwise could benefit from simple heart scans to avoid them because of misleading information on radiation exposure of a different test.

Thank you.

Red yeast rice alert

While there have been some positive reports in the media lately about the cholesterol-reducing effects of red yeast rice, Consumer Lab has issued a very concerning report.

Because Consumer Lab is a subscription website (incidentally, the $20 per year membership fee is money well spent for insightful tests on many supplements, though new reports only come out a handful of times per year), I won't discuss the results of their red yeast rice in its entirety.

However, Consumer Lab testing uncovered several disturbing findings:

--The lovastatin content varied by a factor of 100, from 0.1 mg per tablet/capsule in one brand up to 10.6 mg in another brand. By FDA regulations, lovastatin is a drug and NO red yeast rice preparation is supposed to contain ANY lovastatin. Nonetheless, despite the marketing of supplement manufacturers, it is probably the lovastatin that is largely responsible for the LDL-reducing effect. The monacolins or mevinolins in red yeast rice add little, if any, further LDL-reducing effect.

--Several preparations contain a potential kidney toxin called citrinin. The Walgreen's product, specifically, contained substantial quantities of this toxin.



Interestingly, the FDA has taken repeated action against red yeast rice manufacturers and distributors because they continue to contain lovastatin. In the FDA's most recent action in August, 2007, for instance, Swanson's product and Sunburst Biorganics' Cholestrix, were both sent letters to stop selling their product because it contained lovastatin.

The Consumer Lab findings would explain the enormous variation in LDL-reducing effect of various red yeast rice products. In my experience, some work and reduce LDL 40 mg/dl or so, some fail to reduce LDL at all, others generate a modest effect, e.g., 5-10 mg/dl LDL reduction.

In effect, red yeast rice IS a statin drug, albeit a highly variable and weak one. Although readers of The Heart Scan Blog know that I am a big fan of nutritional supplements and self-empowerment in health, I am a bigger fan of truth. I despise B--- S---- of the sort that emits from some nutritional supplement manufacturers and drug companies.

I am puzzled by much of the public's readiness to embrace a statin drug if it comes from a supplement company while avoiding it if it comes from a drug manufacturer. Personally, I do not like the drug industry, their questionable (at best) ethics, their aggressive marketing tactics, their sleazy sales people.

But, in this instance, if a statin effect is desired, I'd reach for generic lovastatin before I purchased red yeast rice. The Consumer Lab report tells us that red yeast rice IS essentially a statin drug, an inconsistent one that often contains a potential toxin.

"Average amount of heart disease for age"

A 72-year old woman came to my office after a complicated hospital stay (unrelated to heart disease). She'd undergone a CT coronary angiogram and heart scan as part of a pre-operative evaluation prior to a surgery for a non-heart related condition.

The heart scan portion of the test (I was impressed they even did this) yielded a heart scan score of 212. The CT coronary angiogram portion of the test revealed a 50% blockage in one artery, a lesser blockage in one other artery.

The cardiologist consulting on the case advised her that the amount of coronary disease detected was insufficient to pose risk during her surgical procedure. He also advised her that she had "an average amount of disease for age." He thought that nothing further was necessary since she was "average."

Say what?  

What if I told you that you have an average amount of cancer for your age? After all, cancers become more common the older we get. Who would find that acceptable?

Then why should ANY amount of coronary atherosclerotic plaque be "acceptable for age"? Coronary plaque is a degenerative disease that poses risk for rupture. While it is indeed common, by no means should it be acceptable.

I would bet that this same cardiologist would be from the same school of thought that would be eager to advise heart catheterization, stent, and other procedures--revenue-generating procedures--should she have a heart attack appropriate for age.

I wish that I could tell you that this silly comment was provided by some peculiar, "everyone-knows-he's-crazy" doctor. But it was not. It was a solidly mainstream physician. He pooh-poohs nutrition, laughs when asked about nutritional supplements, thinks anyone complaining about symptoms less than a full-blown heart attack is a baby. He is respected by the primary care physicians, lectures on the advantages of prescription medications. In short, he is your typical conventional cardiologist.

This is the way they think. I know, because I was one of them. Thankfully, something banged me upside my head one day (my Mother's sudden cardiac death) and tipped me off to the painful irony of the conventional approach to heart disease.

There is NO amount of coronary disease appropriate for age. This notion is a remnant of the paternalistic, "I-know-better-than-you" attitude of the last century of medicine.

The 21st century promises a new age.

Quantum leaps

A reader of The Heart Scan Blog and member of the Track Your Plaque program posted this comment on The Heart.org:

*The facts speak for themselves.*

Dr. William Davis and Dr. William Blanchet, your patients thank you for the low cost PREVENTIVE care you prescribe. The published facts speak for themselves. It is indeed a sad state of affairs, that the larger cardiology community does not take the time to research the data and results you have been reporting. Unfortunately it is the patients who are the victims of the mainstream, inappropriate, treatment protocols, as evidenced with the ongoing high rate of CV death rate.

I am dumbfounded by the lack of open-minded inquisitive curiosity to thoroughly research your claims by many/most cardiologists. Understood, we are all busy, but that is no excuse to stick with practices that do not result in major breakthrough improvements in patient outcomes.

Then again, we are all humans, and when "we" are convinced that "our" approach is correct, "we" tend to conveniently ignore any evidence to the contrary. "We" like to believe "we" have been right all along.

A very insightful book, recently published, says it all in its title: "Mistakes were made (but not by me)."

From the intensity of the comments on this topic, it is clear that we are in the middle of a battlefield. It is to be hoped that the facts will become visible before too much smoke obscures the field, and before the patients are all dead.

George Orwell said it correctly, back in 1946:

“We are all capable of believing things which we know to be untrue, and then, when we are finally proved wrong, imprudently twisting the facts so as to show that we were right. Intellectually, it is possible to carry on this process for an indefinite time: the only check on it is that sooner or later a false belief bumps up against solid reality usually on a battlefield.”

And, after several posts that preventive care with EBT would be too costly.....

*Heroic*

Prevention is what matters, but it is not very heroic. A hospital that advertises the highest volumes in heart bypasses and other heart "repair" procedures, sounds to many like a go-to place when one gets into trouble with one's heart.

Cardiologists who perform impressive surgical procedures are heroes. Not unlike fire-fighters. We celebrate them (deservedly!) for rescues and life saving heroic actions.

We tend to not pay much attention to the folks that work hard to minimize risk of calamities in the first place.

Similarly, we recently learned that it is too costly to build schools that are earthquake resistant in China. Parents had to look at their children's bodies, crushed.

Is it too graphic to imagine 20,000 American bodies, who died of heart disease, piled up on a field?

What will it take before we make prevention our first priority?


AL, Ann Arbor, Michigan


The reader also tells me that, prompted by his father's death from heart attack while following conventional advice after heart catheterization, he has lost 50 lbs and corrected his lipid patterns on the Track Your Plaque program. The reader is currently struggling with full correction of his severe small LDL pattern and is following some of the advice we discussed on our webinar recently.

Another Heart Scan Blog reader, Stan the Heretic, posted this quote from scientist, Max Planck, in his comment:


"A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it." - M. Planck

(Max Planck was a German physicist who developed quantum theory, a disruptive set of ideas that supplanted other explanations of energy mechanics of the day.)


I fear that may prove to be the case for heart disease. The revenue-generating formula for heart disease management that dominates practice in cardiovascular medicine today is so deeply ingrained into the thinking and revenue expectations of practicing cardiologists that a preventive or reversal approach just won't cut it--even if it is vastly superior.

That's why it is important for you to take control yourself. You will be the one who obtains and applies the information that saves your life or the lives of those around you. It is, in all likelihood, NOT your doctor who will save your life, but YOU.

Body count

Imagine the following headline:

War in Iraq a growing success: 20,000 Americans now dead!


If a newspaper ran that headline, we would all be outraged, and rightly so. Deaths in war are a tragedy. They are not something we celebrate.

Then why do we hear hospitals boasting about the number of bypass operations performed every year, number of heart catheterizations performed, number of heart attacks treated?


"_______ Hospital breaks 1000-heart bypass per year milestone"

"We treat more heart attacks than other other hospital in the state!"

"More people come to ________ Hospital than any other in the region!"




I hear this stuff on the radio, on TV, see it in newspapers and magazines, even on highway billboards every single day in Milwaukee.

Heart procedures, like deaths in war, are casualties of health.

They are not successes (though, of course, you can have a "successful" bypass). I see most procedures as a failure of prevention.

Death from heart attack is a failure of prevention. Tim Russert's death was a (unnecessary) failure of prevention. But so are bypass surgery, stents, and the like.

Such is the perverse state of affairs in hospitals and health: They celebrate illness. They glamorize it with ads displaying high-tech equipment, efficient staff in scrubs, "caring and friendly staff." But it is illness they are celebrating. Why? Because it has become a business necessity, a necessary strategy to remain competitive and profitable in the business called "healthcare" that makes money from treating people. The biggest return is from major procedures like bypass operations.

Every success in prevention denies the hospital an $80,000+ opportunity. You'll never hear that advertised.
