No more Lovaza

30. July 2010 William Davis (45)

That's it: I will NEVER ever write another prescription for Lovaza.

I actually very rarely write a prescription for Lovaza, i.e., prescription fish oil. But this was the last straw.

I advised a patient that we've had good success using high-doses of fish oil to reduce lipoprotein(a), Lp(a). 6000 mg per day of the omega-3 component (EPA + DHA) from fish oil reduces Lp(a) in 60% of people after one year. (Recall that Lp(a) is the most aggressive known lipid-related cause of heart disease.)

The two preparations I generally suggest are either the very affordable Sam's Club Members Mark Triple-Strength Fish Oil with 900 mg EPA + DHA per capsule: 7 capsules per day. Another great product (my personal favorite because of its extreme purity--it doesn't even smell like fish oil): Pharmax Finest Pure Fish Oil with 1800 mg EPA + DHA per teaspoon: 3 to 3 1/2 teaspoons per day.

Both preparations work great and are quite affordable, given the high dose. For the Sam's Club preparation, it will cost around $30 per month, while the Pharmax liquid will run around $49 per month.

Well, the woman's husband insisted on a prescription for Lovaza. One Lovaza capsule contains 784 mg EPA + DHA per capsule: 7 to 8 capsules per day.

Here are some prices for Lovaza from online pharmacy discounters:
Prescription Giant: $78.99 for 30 capsules ($2.63 per capsule)
Planet Drugs Direct: $135 for 100 capsules ($1.35 per capsule)

These are lower than the prices I obtained in past by calling local pharmacies in my area, quite a bit lower, in fact.

Filling the Lovaza prescription at Prescription Giant will therefore cost $552.93 to $631.92 per month; at Planet Drugs Direct it will cost $283.50 to $324.00 per month. At local pharmacies, a similar 7 to 9 capsules Lovaza per day will cost upwards of $800 to $900 per month.

The patient's husband insisted on the Lovaza prescription because he knew that his insurance would cover it. When I pointed out that this was a large cost that would have to be borne by others in their healthcare premiums, he said that didn't matter to him.

I hesitated, but ended up writing the prescription for 7 Lovaza capsules per day. As soon as I handed to him, I regretted it. In fact, I am embarassed and angry at myself for having given in.

So I vowed: I will NEVER EVER write another prescription for Lovaza.

I do not believe that we should spread the excessive profiteering of the pharmaceutical industry around on the backs of people who pay their healthcare insurance premiums, just so that a few people, like this selfish couple, can save a few dollars a month.

This is your brain on wheat II

29. July 2010 William Davis (24)

In the original Heart Scan Blog post, This is your brain on wheat, I discussed how opioid peptides (i.e., small proteins that act like opiates such as heroine or morphine) that result from digestion of wheat cause unique effects on the human brain, particularly addictive behaviors. I also briefly reviewed how elimination of wheat has been shown to reduce auditory hallucinations and other psychotic behaviors in a subset of people with paranoid schizophrenia.

These two phenomena, addictions and schizophrenia, are most likely the result of exorphins that cross the blood-brain barrier. Exorphins--exogenous morphine-like compounds--can be blocked by opiate-blocking drugs like naloxone and naltrexone. Naloxone is used in hospitals to reverse morphine or heroine overdoses; naltrexone is being repackaged into a weight loss drug, since blocking wheat-derived exorphins reduces appetite. (Yes: The USDA tells us to eat more wheat, the drug industry sells us the antidote.)

There's another way that wheat can affect the brain and nervous system: immune-activated damage.

This is similar to the effect seen in celiac. There's even overlap with some of the antibody markers used to diagnose celiac, like the anti-gliadin antibodies and the anti-endomysium antibodies.

The most common immune neurological syndrome consequent to wheat consumption is cerebellar ataxia, a condition in which an immune response causes damage to the Purkinje cells of the cerebellum, the portion of the brain responsible for balance and coordination. This results in stumbling, incoordination, incontinence, and eventually leads to reliance on a cane or walker and wearing a diaper. Average age of onset: 53 years. A shrunken, atrophied cerebellum can be seen on an MRI of the brain.

Problem: Most people with central nervous system damage caused by wheat do not have any intestinal symptoms, like diarrhea and abdominal pain, the sort of symptoms usually associated with celiac disease. It means the first sign of wheat-induced brain damage may be bumping into walls and wetting your pants.

There's no such thing as a "no-carb" diet

27. July 2010 William Davis (24)

When I tell patients how I advise a wheat-free, cornstarch-free, sugar-free diet on the background of a low-carbohydrate diet, some people ask: "But can I live on a no-carb diet?"

Well, there's no such thing as a "no-carb" diet. Low-carb, yes. No-carb, no.

Here are the carbohydrate contents of various "low-carb" foods:

Gouda cheese--3 oz contains 1.65 grams carbohydrates
Mozzarella cheese--1 cup contains 2.89 grams carbohydrates
Walnuts--4 oz (56 nuts) contains 2.96 grams carbohydrates
Almonds--4 oz contains 1.38 grams carbohydrates
Sour cream--one-half cup contains 3.31 grams carbohydrates
Red wine--3.5 oz glass contains 2.69 grams carbohydrates
Eggplant--1 cup cooked contains 8.33 grams carbohydrates
Green pepper--1 medium-sized raw contains 5.52 grams carbohydrates
Cucumber--1 medium contains 4.34 grams carbohydrates
Tomato--1 medium contains 4.82 grams carbohydrates

(Nutrition data from USDA Nutrient Database)

In other words, foods thought to be "low-carb" actually contain a modest quantity of carbohydrates.

Such modest quantities of carbohydrates may not be enough to trip your blood sugar. But add up all the "low-carb" foods you consume over the course of a day and you can easily achieve 30 grams or more carbohydrates per day even without consuming any higher carbohydrate foods.

Why doesn't your doctor try to CURE diabetes?

21. July 2010 William Davis (88)

Imagine you have breast cancer. You go to your doctor and she says, "As your pain worsens, we'll help you with pain medication. We'll fit you with a special bra to accommodate the tumor as it grows. That's all we're going to do."

"What?" you ask. "You mean just deal with the disease and its complications, but you're not going to help me get rid of it . . . cure it?"

It would be incredibly shocking to receive such advice. Then why is that the sort of advice given when you are diagnosed with diabetes?

Say you go to the doctor. Lab values show a fasting blood sugar of 156 mg/dl, HbA1c (a reflection of your previous 60 days average glucose) of 7.1%. Both values show clear-cut diabetes.

Your doctor advises you to 1) start the drug metformin, then 2) talk to the diabetic teaching nurse or dietitian about an American Diabetes Association (ADA) diet.

The ADA diet prescribed encourages you to increase carbohydrates and cut fats at each meal and maintain a consistent intake so that you don't experience hypoglycemic (low blood sugar) episodes. You follow the diet, which causes you to gain 10-15 lbs per year, increasing your "need" for diabetes medication. You doctor adds Actos, then Januvia, then injections of Byetta.

Three years and 34 lbs later, you are not responding well to the drug combination with blood sugars rarely staying below 200 mg/dl. You've developed protein in your urine ("proteinuria"), lost 30% of your kidney function, and you are starting to lose sensation in your feet. So the doctor replaces some of your medication with several insulin injections per day.

This formula is followed millions of times per year in the U.S. So where along the way did your doctor mention anything about a "cure"?

Adult diabetes is the one chronic disease that nobody cares to cure. Treat it, maintain control over blood sugars, but cure it? Most physicians say it's impossible.

The tragedy is that diabetes is a curable condition. I've seen it happen many times. Physicians dedicated to curing diabetes like low-carb expert, Dr. Mary Vernon, have cured it countless times. Dr. Eric Westman and colleagues have been building the case for the carbohydrate-restricted cure for diabetes with studies such as this. In this last study, of the 8 participants on insulin + medications at the start of the study, 5 no longer required medications at the close of the study--they were essentially non-diabetic.

I tell patients that diabetes, in fact, is a disease you choose to have or not to have--provided you are provided the right diet and tools. Sadly, rarely are diabetics told about the right diet and tools.

That's why Cadbury Schweppes has been a major contributor to the American Diabetes Association, as are other processed food manufacturers and the drug industry, all who stand to profit from maintaining the status quo.

The cure? Eliminate or at least dramatically reduce carbohydrates, the foods that increase blood sugar.

Note: If you have diabetes and you are taking any prescription agents, such as glyburide, glipizide, insulin, and some others, you will need to discuss how to manage your medications if you reduce carbohydrates. The problem is finding a doctor or other resource to help you do this.

LDL pattern B

18. July 2010 William Davis (17)

Here's a Q&A I stumbled on in the Forum of MedHelp, where people obtain answers from presumed health "experts."

Question:

My VAP test results in July 07 identified an LDL Pattern B.
Overall results:
Total 150
HDL 75
LDL 61
Trig 60
HDL-2 17
LP(a) 6.0
LDL Pattern B

Medications:
Lipitor 10mg
Zetia 10mg
Altace 10mg
Atenolol 50mg
Plavix 75mg
Aspirin 81mg

I had several heart attacks which resulted in CABG performed May 2000. I am a 53 year old white male , 6'1", 190 pounds, exercise every day, watch my diet and feel great. Everything looks OK except my LDL Pattern B. Is there any therapy to improve the Patten B?

Answer from CCF, MD:
Your results indicate an LDL pattern B, which generally indicates small atherogenic LDL particles which may cause increased risk for CAD. However, there are several problems with LDL patterning: 1) its unreliability (of LDL pattern testing ), 2) unclear clinical evidence regarding regarding the usefulness of LDL patterns and particle size. The majority of evidence regarding the progression of atherosclerosis is with LDL lowering and to an smaller extent HDL raising.

All available clinical evidence shows that any particles in the VLDL, IDL, or LDL range are atherogenic, and there is no evidence that whether belonging to pattern A or B one is more atherogenic than others.

Subclass studies have proliferated over the last few years, but many of these studies were funded or subsidized either by suppliers of the assays as a method to expand their use and move them into mainstream practice, or by pharmaceutical companies in an attempt to claim some advantage over other therapeutic agents.
Thus, current data on LDL subclasses are at best incomplete and at worst misleading, suffering from publication bias, and now given the recent results of the Ensign et al. study, unreliable.

Your LDL, and HDL are at goal. The Lpa level is still not clearly linked as a modifiable risk factor for CAD, although elevated levels are now know to be linked to stroke.

Continue with your present treatments: aspirin, plavix, ateonol and altace are all essential medications.

Wow. The extent of ignorance that pervades the ranks of my colleagues is frightening.

Contrary to the response, LDL particle size assays are quite reliable and accurate. I've performed many thousands of lipoprotein assays and they yield reproducible and clinically believable results. For example, eliminate wheat, oats, cornstarch, and sugars and small LDL drops from 2400 nmol/L to 893 nmol/L (NMR)--huge drops. If repeated within a short period of time, the second measure will correspond quite closely.

The data are also quite clear: Small LDL particles (i.e., "pattern B") are a potent predictor of cardiovascular events. What we lack are the treatment trials that show that reduction of small LDL results in reduced cardiovascular events. The reason for this is that small LDL research is not well-funded, since there is no prescription drug to treat small LDL, only nutritional means. Niacin (as Niaspan) is as close as it comes for a "drug" to reduce small LDL. But diet is far more effective.

Given the questioner's fairly favorable BMI of 25.1 and his history of aggressive heart disease, it is virtually certain that he has what I call "genetic small LDL," i.e., small LDL that occur on a genetically-determined basis (likely due to variants of the cholesteryl-ester transfer protein, or CETP, or of hepatic lipase and others).

Ignoring this man's small LDL will, without a doubt, consign him to a future of more heart attacks, stents, and bypass. Maybe by that time the data supporting the treatment of small LDL will become available.

What increases blood sugar more than wheat?

15. July 2010 William Davis (38)

Take a look at these glycemic indexes (GI):

White bread 69
Whole wheat bread 72
Sucrose 59
Mars bar 68
White rice 72
Brown rice 66

I've made issue in past of whole wheat's high GI--higher than white bread. Roughly in the same glycemic league as bread are shredded wheat cereal, brown rice, and a Mars candy bar.

With few exceptions, wheat products have among the highest GIs compared to the majority of other foods. For instance:

Kidney beans 29
Chick peas 36
Apple 39
Ice cream 36
Snickers Bar 40

Yes, by the crazy logic of glycemic index, Snickers is a low-glycemic index food.

While I do not believe that low GI makes a food good or desirable, since low GI foods still provoke high blood sugars, small LDL particles, trigger glycation, and other abnormal phenomena, they are clearly less obnoxious than the items in the first list.

Take a look at this list:

Cornflakes 80
Rice cakes 80
Rice Krispies 82
Rice pasta, 92
Instant potatoes 83
Tapioca 81

Starches that are dried and/or pulverized, such as cornstarch, potato starch, rice starch, and tapioca starch (cassava root) will increase blood sugar even more than wheat. Foods with these starches have GI's of 80-100.

Cornstarch, potato starch, rice starch, and tapioca starch: Sound familiar? These are the main starches used in "gluten-free" foods. A hint of the high GI behavior of these dried starches is seen in the GI for cornflakes of 80.

So remember: Wheat-free is not the same as gluten-free. Gluten-free identifies junk carbohydrates masquerading as healthy because they don't contain one unhealthy ingredient, i.e. wheat.

China fiction?

10. July 2010 William Davis (39)

Dr. Colin Campbell caused a stir with publication of his 2005 book, The China Study. Dr. Campbell, after extensive animal and epidemiologic research conducted in China over 20 years, concluded that a diet high in animal protein, especially casein, was associated with increased cancer, osteoporosis, and heart disease risk.

Richard Nikoley of Free the Animal and Stephan Guyenet of Whole Health Source have been talking about an analysis of the China Study raw data performed by a young woman named Denise Minger.

Denise's analysis is nothing short of brilliant, absolutely "must" reading for anyone interested in nutrition.

Her comments on the relationship of wheat to heart disease:

Why does Campbell indict animal foods in cardiovascular disease (correlation of +1 for animal protein and -11 for fish protein), yet fail to mention that wheat flour has a correlation of +67 with heart attacks and coronary heart disease, and plant protein correlates at +25 with these conditions?

Speaking of wheat, why doesn’t Campbell also note the astronomical correlations wheat flour has with various diseases: +46 with cervix cancer, +54 with hypertensive heart disease, +47 with stroke, +41 with diseases of the blood and blood-forming organs, and the aforementioned +67 with myocardial infarction and coronary heart disease?

Carbohydrate-LDL double whammy

9. July 2010 William Davis (14)

Carbohydrates in the diet trigger formation of small LDL particles. Because carbohydrates, such as products made from wheat, increase triglycerides and triglyceride-containing lipoproteins (chylomicrons, chylomicron remnants, VLDL, and IDL), LDL particles (NOT LDL cholesterol) become triglyceride-enriched. Triglyceride-enriched LDL particles are "remodeled" by the enzyme, hepatic lipase, into triglyceride-depleted, small LDL particles.

The list of reasons why small LDL particles are more atherogenic, i.e., plaque-causing, is long:

--Small LDL particles, being smaller, more readily penetrate the endothelial barrier of the arterial wall.
--Small LDL particles are more adherent to glycosaminoglycans in the artery wall.
--Small LDL particles are poorly taken up by the liver LDL receptor, but enthusiastically taken up by macrophage receptors of the sort in your artery walls.
--Because of their poor liver clearance, small LDL persists in the bloodstream far longer than large LDL.
--Small LDL particles are more oxidation-prone. Oxidized LDL are more likely to trigger inflammatory phenomena and be taken up by macrophages in the artery wall.

Let me add another reason why small LDL particles are more likely to cause plaque: They are more likely to undergo glycation. (More on glycation here.)

Glycation occurs when glucose (sugar) molecules in the blood or tissue modify proteins, usually irreversibly. Small LDL particles are uniquely glycation-prone. (This is likely due to a conformational change of the apoprotein B in the small LDL particle, exposing lysine residues along apo B that become glycated.)

Here's a great demonstration of this phenomenon by Younis et al:

"LDL3" is the small type. Note that small LDL particles are 4-5 times more glycated than large LDL. That's a big difference.

Once glycated, small LDL is especially resistant to being taken up by the liver. Like annoying in-laws, they hang around and hang around and . . . The longer they hang around, they more opportunity they have to contribute to plaque formation.

So, carbohydrates trigger formation of small LDL particles. Once formed, small LDL particles are glycated when blood sugar increases. While LDL can be glycated even when blood sugars are in the normal range (90 mg/dl or less), glycation goes berserk when blood sugars go higher, such as a blood sugar of 155 mg/dl after a bowl of steel-cut oatmeal.

To lose weight, prick your finger

8. July 2010 William Davis (45)

We know that foods that trigger insulin lead to fat storage. Putting a stop to this process allows you to mobilize fat and lose weight. If you're starting out from scratch, rapid and dramatic weight loss can be experienced, as much as one pound per day.

So how can you stop triggering insulin?

The easiest way is to eliminate, or at least minimize, carbohydrates. My favorite method to restrict carbohydrates is to eliminate wheat and minimize exposure to other carbohydrates, such as oats, cornstarch, and sugars. All these foods, wheat products worst of all, cause blood sugar and insulin to skyrocket.

Another way is to check your blood sugar one hour after completing a meal and keep your after-eating, or "postprandial," blood sugar 100 mg/dl or less. Let's say you are going to eat stone ground oatmeal, for example. Blood sugar prior to eating is, say, 90 mg/dl. One hour after oatmeal it's 168 mg/dl--you know that this is going to trigger insulin and make you fat. Oatmeal should therefore be eliminated.

Keeping blood sugar to 100 mg/dl or less after eating teaches you how to avoid provocation of insulin. A shrinking tummy will follow.

To do this, you will need:

1) A glucose meter--My favorite is the One Touch Ultra Mini ($13.42 at Walmart). It's exceptionally easy to use and requires just a dot of blood. Drawback: Test strips are about $1 each. Accuchek Aviva is another good device. (We've had a lot of problems with Walgreen's brand device.)
2) Test strips--This is the costly part of the proposition. Purchased 25 or 50 at a time, they can cost from $0.50 to $1.00 a piece.
3) Lancets--These are the pins for the fingerstick device that comes with the glucose meter. A box should be just a few dollars.

No prescription is necessary, nor will insurance pay for your costs unless you're diabetic. To conserve test strips, use them only when a new, untested food or food combination is going to be consumed. If you had two scrambled eggs with green peppers, sundried tomatoes, and olive oil yesterday and had a one hour postprandial glucose of 97 mg/dl, no need to check blood sugar again if you are having the same meal again today.

Iodine update

2. July 2010 William Davis (30)

As the iodine experience grows, I've made several unique observations.

Up to several times per day, I see people who are responding in some positive way to iodine supplementation. (See previous Heart Scan Blog posts about iodine: Iodine deficiency is REAL and The healthiest people are the most iodine deficient.)

Among the phenomena I've observed:

1) A free T4 thyroid hormone at the low end of normal, or even in the below normal range, along with a highish TSH (usually >1.5 mIU/L) are the most frequent patterns that signal iodine deficiency. Occasionally, a low free T3 value will also increase, though this is the least frequent development.

2) At a dose of 500 to 1000 mcg iodine per day, it requires anywhere from 3 to 6 months to obtain normalization of thyroid measures.

3) Reversal of small goiters also occurs over about 6 months.

4) Iodine intolerance is uncommon. If it occurs, using a low starting dose, e.g., 100-200 mcg per day, usually works. The dose can be increased gradually over the ensuing months.

5) Perceptible benefits of iodine occur only occasionally. The most common perceptible effects are increased energy and increased warmth, especially of the hands and feet.

6) Some people who have taken thyroid hormones for years will develop reduced need for their medication with iodine supplementation. In other words, their physician was inadvertently treating iodine deficiency with thyroid hormone replacement. Anyone already on any thyroid preparation(s), e.g., Synthroid, levothyroxine, Armour thyroid, Naturethroid, etc., should watch for signs of hyperthyroidism when iodine is added. But having your own thyroid gland make its own thyroid hormones is better and healthier than relying on the prescription agents. Just be sure to monitor your thyroid measures.

7) Iodine toxicity can occur--Two people in my clinic population developed iodine toxicity by taking 6000 mcg iodine per day for 6 or more months. (Both patients did it on their own based on something they read). Iodine toxicity is evidenced by shutting down your thyroid, i.e., marked increase in TSH, e.g., 15 mIU/L.

Most of the people in my clinic obtain their iodine from kelp tablets. Some use potassium iodine (KI) drops. A handful have used the high-potency Iodoral (12.5 mg or 12,500 mcg iodine per tablet); this was also the form that generated the toxic effects in the two females.

All in all, iodine deficiency is actually far more common than I ever suspected. Not everybody is iodine deficient. But a substantial minority of the Midwest population I see certainly are.

Synthroid, Armour Thyroid, and the battle for T3

6. July 2008 William Davis (2)

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

3. July 2008 William Davis (9)

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

2. July 2008 William Davis (9)

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

29. June 2008 William Davis (6)

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?

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

28. June 2008 William Davis (7)

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.

Dr. Bill Blanchet: A ray of sunshine

26. June 2008 William Davis (4)

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

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

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

Here, a sample of his wonderfully persuasive comments:

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

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

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

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

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

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

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

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

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

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

Wow! I couldn't have said it better.

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

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

The Russert Protocol at work

25. June 2008 William Davis (6)

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

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

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

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

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

Further investigation in Keith uncovered:

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

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

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

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

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

Petition to the National Institutes of Health

24. June 2008 William Davis (2)

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

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

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

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

The petition reads:

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

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

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

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

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

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

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

Thank you.

I added my comment:

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

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

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

If you are interested in adding your voice, you can also electronically sign the petition. It is optional, but you can also add your own comments regarding your own views or experiences.

Wheat withdrawal

24. June 2008 William Davis (16)

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

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

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

How about wheat?

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

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

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

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

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

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

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

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

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