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.

What Mr. Clinton did NOT do

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

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



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

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


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

Magnesium and arrhythmia

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

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

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

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



Dr. Davis,

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

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

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

Thank you SO MUCH!

Warmly,
Catherine C.

Thinner by Thursday

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

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

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

Wheat elimination.

Omega-3 Index: 10% or greater?

We've previously considered the question:

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

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





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

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

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

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

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

Let's soak 'em with fish oil

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


Hello Dr. Davis,

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

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

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

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

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

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

Sincerely JP, Tennessee



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

Heart scan gone wrong

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

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


Dr. Davis,

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

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

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

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

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

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

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

BU, Michigan



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

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

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

Blood sugar: Fasting vs. postprandial

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

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

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

It is shockingly common.

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

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

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

Diabetes from fruit

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

The sniff test

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

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