The Track Your Plaque “Rule of 60”

6. November 2006 William Davis (0)

The Track Your Plaque recommended targets for conventional lipids (i.e., LDL, HDL, triglycerides) are LDL 60 mg/dl, HDL 60 mg/dl, and triglycerides 60 mg/dl: 60-60-60.

Not only is this set of values easy to remember—60-60-60—but is grounded in science and the results of clinical trials.

LDL 60 mg/dl
The LDL target is based on experiences such as that of the Reversal Trial, the PROVE-IT Trial, and the Asteroid Trial, all of which showed that LDL cholesterol values in the range of 60 mg/dl dramatically enhance the likelihood of stopping plaque growth or achieving regression, reducing risk of heart attack more than more lenient LDL targets.

HDL 60 mg/dl
Achieving HDL cholesterol of 60 mg/dl is not as well grounded as LDL targets, mostly because increasing HDL is more difficult. There’s also no tremendously profitable way to raise HDL, as there is for reducing LDL (statin drugs). But epidemiologic observations strongly suggest that HDL of 60 mg/dl provides maximum control over both coronary plaque growth, as well as slashing rates of heart attack. Numerous smaller trials have borne this phenomenon out.

Triglycerides 60 mg/dl
Triglycerides of 60 mg/dl is based principally on studies that have shown a virtual elimination of abnormal lipoproteins, especially small LDL, when this value is achieved. Reduction of triglycerides is an effective means to reduce hidden lipoproteins like small LDL and VLDL. Triglycerides in the conventionally acceptable range of 100-150 mg/dl can be associated with dramatic abnormalities of lipoproteins.

Thus, the Track Your Plaque “Rule of 60”. In our day to day experience of trying to stamp out plaque growth from its terrifyingly rapid 30% per year, or reversing it—-dropping your heart scan score—-the Rule of 60 has held up time and again. Getting your lipids to 60 mg/dl does not guarantee that plaque growth stops, but it appears to be a necessary requirement that tips the scales heavily in your favor.

Those of you who’ve discussed lipid targets with your doctor will quickly recognize that the Track Your Plaque targets appear laughably ambitious, perhaps unnecessary. Recall that your doctor likely has no idea of what coronary plaque regression means. He/she likely conforms to the lax targets set by the National Cholesterol Education Panel (NCEP). (These targets depend on a number of factors such as whether you’re diabetic, sex, risk factors, etc.) Based on trial experiences like the few mentioned above, as well as my experience with purposeful coronary plaque reversal, the lipid guidelines as advocated by NCEP guarantee heart disease. Let me emphasize that again: Follow the guidelines set by the NCEP for your doctor to follow, and progression of heart disease is a virtual certainty. At best, it may slow growth of plaque and delay your heart attack or bypass surgery, but it will not stop it.

Now, that point made, let me make another: Just knowing about the targets and even becoming a member of the Track Your Plaque program does not mean that your lipids with automatically go to 60-60-60. We’ve actually had an occasional person tell us that they were disappointed that, by becoming Members, why hadn’t their lipids gone to 60-60-60?

Knowing that the 60-60-60 targets provide real advantage is not the same as actually achieving them.

A little bit of fish oil

5. November 2006 William Davis (12)

The British National Health Service (NHS) has announced that, in light of the substantial data documenting that omega-3 fatty acid intake from fish reduces likelihood of cardiovascular events by around 40%, that Brits discharged from hospital following a heart attack should be "prescribed" 1000 mg of prescription fish oil per day.

Hardly a revolutionary concept. Part of the timidity of the British NHS seems to relate to the potential cost to the government, since apparently much of the cost will be borne by the government-subsidized health system.

But prescription fish oil? Why prescription fish oil? Prescription Omacor, one capsule per day, costs around $70 (U.S.) per month. If I go to Sam's Club the same quantity of omega-3 fatty acids (in three capsules) will cost around $2.50. That's less than 5% of the cost of the prescription form.

Omacor is clearly more concentrated. But is the prescription form better--more effective, more purified, less contaminated, etc.? I have seen no independent verification of this. Of course, manufacturers make all sorts of claims. The only independent, unbiased testing I'm aware of comes from organizations like Consumer Reports and www.consumerlabs.com. Omacor has not been compared to non-prescription fish oil in any of their analyses. Head-to-head comparison of Omacor to nutritional supplement fish oil is unlikely to come from Solvay, the manufacturer of Omacor. Drug companies powerfully resist head-to-head comparisons, fearing it will not play out in their favor. Let the public remain ignorant and hope marketing conquers all.

Why would the NHS only recommend eating fish and prescription fish oil? I don't know, but it smells awfully fishy to me. As soon as an opportunity for profit is built into a treatment, all of a sudden it gains endorsement. Perhaps lobbying by those parties with potential for profit drove the process.

Nonetheless, despite the filthy politics and under-the-table dealings, some good comes out of the NHS's action: broader recognition of the power of fish oil. Perhaps when a British patient or an American patient gets discharged with a prescription for Omacor, the patient will take the initiative and go to the health food store instead and save him (or his insurer) $67.50 per month.

For your coronary plaque control program and control and/or reversal of your heart scan score, we start at 4000 mg per day of standard fish oil, providing 1200 mg per day of omega-3 oils. This amount as a nutritional supplement costs only a few dollars a month. And you have the satisfaction of not only taking a powerful step for your health, but also not enriching the overflowing pockets of drug companies.

AHA: Doctors don't have time for prevention

3. November 2006 William Davis (0)

Doctors "don't have enough time to educate their patients and to stop and think about what measures the patient really needs," says Dr. Raymond Gibbons, new head of the American Heart Association.

Dr. Gibbons highlighted how the system reimburses generously for performing procedures, but reimburses relatively little (often just a few dollars) for providing preventive counseling. He claims to have several ideas for solutions.

Good for Dr. Gibbons. There's no doubt that the lack of truly effective preventive information and counseling is a systemic, built-in flaw in the current medical environment. It is especially true in heart disease.

Another problem: "If a doctor didn't say it, it must not be true." That's the attitude of many of my colleagues. Despite their broad and systematic failure to provide preventive counseling, most physicians (my colleagues the cardiologists especially) pooh-pooh information that comes from other sources. Yet, it's my prediction that much of healthcare will go the way of optometry--direct access to care, often delivered in non-healthcare settings like a store or mall. People are hungry for truly self-empowering health information. Too many physicians can't or won't provide it. You've got to turn elsewhere for it.

That's one of the main reasons I set up the Track Your Plaque program. It's direct access to self-empowering information. A flaw: You still require the assistance of a physician to obtain lab values, lipoproteins, and to monitor certain treatments (e.g., niacin at higher doses). If I knew of a way around this, I'd tell you. But right now I don't. We remain constrained by legal and moral obligations.

Nonetheless, phenomena like CT heart scanning and the Track Your Plaque program are just a taste of things to come.

Confusion about Lp(a)

3. November 2006 William Davis (2)

Since the recent reader question about Lp(a), I've had several other instances of confusion over Lp(a).

To help you navigate through some of the often confusing issues behind this complex genetic abnormality, here are some common sense rules to follow. When you ask your doctor to draw a Lp(a), try to be certain that:

--the same laboratory is always used. Just going from lab to lab can account for huge variation in Lp(a). As standardization proceeds internationally, this will be become less important. But in 2006, it's still an issue.

--you and your doctor resist the temptation to check Lp(a) frequently. I saw a patient recently who was having Lp(a) levels nearly every month. This is pointless. Lp(a) changes very slowly. Checking it frequently will not allow any treatment to be fully reflected. All you'll observe is random variation that can be frustrating. We wait at least 6 months before re-checking after a new treatment is introduced.

If you have a choice, I would recommend you opt for the measure provided by Liposcience (NMR). The technique they use is a particle count measure, rather than a weight-based measure. This may be more accurate, particularly when Lp(a) is small.

Lp(a) remains among the more difficult patterns to understand and correct. Don't be surprised if you encounter a lot of confusion from your doctor, as well. You may end up providing much of his/her education.

Calculus of the cardiologist

2. November 2006 William Davis (1)

I call this the "calculus of the cardiologist":

Heart procedures = big money

More procedures = more big money

You do the math. If you do more procedures, you get more money.

What if your patients don't need more procedures? That's easy. You lower the bar on reasons to do procedures. You scare the pants off people and lead them to think that all heart disease or questions about heart disease are potentially life-threatening. You could even appear to be doing the patient a big favor. "My Lord! This is potentially dangerous. We need to perform a procedure without delay!"

There are incentives beyond direct cash payment. A patient of mine today showed me a memo to employees in his company that showed why certain hospitals are targeted for care. The criteria for choosing centers was based on number of procedures performed. In other words, the more procedures performed at a hospital, the more procedures will be directed there. Of course, this makes sense at some level. More procedures can also mean greater skill.

But have we lost sight of the fact that the mission is not more procedures and more money, but to get rid of a disease? If the intensity of effort devoted to heart procedures were re-directed to early detection, prevention, and reversal of disease, we'd have half the hospitals we now have. We'd also chop a huge chunk out of the national healthcare budget.

Lipoprotein(a) treatment alternatives

1. November 2006 William Davis (2)

A question from a reader:

Two years ago, my doctor recommended a comprehensive lipid screening because both of my parents had heart disease. My only blood component way out of line was LP (a) [lipoprotein(a)]. It was 130. According to the lab that conducted the screening, Berkeley Heart Lab, a level above 30 should be cause for concern. I was stunned that mine was more than quadruple the danger level.

I began taking two grams [2000 mg] of niacin a day in addition to the Lipitor I was already taking. The next reading, a few months later, was 87. Over a period of about 18 months, I had a total of four readings from Berkley Heart Lab. My LP (a) fluctuated in the 80-130 range – still way above normal. My doctor said there was little else I could do to control it.

That doctor has since retired. I now see another doctor who uses a different lab. My first LP (a) reading with him a few months ago was 17, which is normal. I am still taking the same amount of niacin and Lipitor and I can’t think of anything that would account for the huge discrepancy. I’m going to have another test again soon.

Is one of the labs giving erroneous readings? If so, how can I tell which? If Berkeley Heart Lab is correct, is there anything I can do about my increased coronary risk due to high LP (a)?
Tom D.

Tom's frustration on the variation of Lp(a) is due to the fact that laboratories run the Lp(a) test by several different techniques and will generate tremendous variation in values. The key is to stick to the same measure over and over from the same lab, else you'll be terribly confused and frustrated. Tom essentially should ignore the value obtained that was unexpectedly low.

Another issue: Lp(a) is a turtle. It responds very slowly. In fact, we rarely check it more than once or twice a year. Check it too soon after a treatment change and it won't fully reflect the effect. You've got to wait at least several months before re-checking.

How about treatment alternatives? They are:

--More niacin. Not my favorite choice, since niacin >2000 mg per day begins to generate more side-effects, but it is a choice. You can go to 4000-5000 per day, but only with your doctor's supervision due to liver effects.

--Testosterone for males. We use topical testosterone from Women's International Pharmacy in Madison, Wisconson. Prescription patches like Testim are also effective.

--Estrogen for females. This is less "clean" than testosterone, introducing questions about endometrial and breast cancer risk, but it is a choice.

--DHEA--A small effect but every little bit can help. We use 25-50 mg per day, depending on blood levels and only if you're 45 years old or older.

--l-carnitine--In my experience, a small effect. It requires 2000 mg per day, which is expensive. Sometimes, an expected large effect develops, so it's worth a try if it fits in your budget.

--Fibrates--These are the drugs Tricor and Lopid. I don't like these agents very much because I think they're weak, including the effect on Lp(a) reduction. But they are choices for you and your doctor.

Lastly, you can simply be guided by your heart scan score. For example, if Tom's initial heart scan score is 200, and he continues his current program and one year later his score is 300, then alternative treatments are worth considering. But what if Tom's score is 189--he's regressed his coronary plaque. Then, who cares what his Lp(a) is?

Another issue to keep in mind is that, in the presence of Lp(a), keeping LDL to very low numbers (e.g., 60 mg/dl) may added value in preventing coronary plaque growth.

Trapped in a low-fat world

1. November 2006 William Davis (2)

If you would like to...

--Reduce (good) HDL

--Raise triglycerides, sometimes by hundreds of points

--Raise blood sugar into the pre-diabetic range

--Raise blood pressure

--Accelerate coronary plaque growth

then go on a low-fat diet like the one promoted by long-time super low-fat advocate, Dr. Dean Ornish. Every day I have to educate patients that a low-fat diet as advocated by Dr. Ornish is a destructive, counter-productive process that makes coronary plaque grow and increases your heart scan score.

If you want to gain control over coronary plaque, do not follow the Ornish program or anything resembling it. The Ornish program is a dead end.

Instead, the crucial components of a healthy diet for plaque control are:

--Low saturated and hydrogenated fat, but not low all fats.

--High monounsaturated and omega-3 fats

--Low glycemic index (i.e., slow sugar release)

--High fiber

That simple. An excellent program to put these limits to practical use is the South Beach Diet. Or, follow the more detailed guidelines on the Track Your Plaque website (open content section).

Blame the niacin

31. October 2006 William Davis (7)

Despite the fact that niacin is:

1) A vitamin--vitamin B3

2) One of the oldest cholesterol-reducing agents around with a long-standing track record of effectiveness and safety

3) Available as a prescription drug as well as a variety of "nutritional supplements"

most physicians remains shockingly unaware of its benefits, effects, and side-effects. Most, in fact, are either ignorant or frightened of advising their patients on niacin use. As a result, I commonly have to tell my patients to resume the niacin that their primary care physician has (wrongly) stopped because of itchy feet, grumpiness, groin rash, urinary tract infections, nightmares, diarrhea, hair loss, runny nose, etc. All of these are REAL reasons doctors have advised patients to stop niacin (though none were actually due to niacin).

Is niacin really that troublesome? No, it's not. In fact, if used properly, it's among the most effective and safe tools available for correction of low HDL, small LDL and other triglyceride-containing lipoproteins, lipoprotein(a), and dramatic reduction of heart attack risk. If added to a statin agent, the heart attack risk reduction can approach 90%.

Statins are just too easy for doctors to prescribe. Niacin, on the other hand, requires a good 15-20 minutes to describe how to use it. It could generate an occasional phone call from a patient who struggles with the annoying but largely harmless and temporary "hot-flush" feeling, a lot like a hot blush. Given a choice, most doctors would simply choose not to be bothered. For this reason, I'll commonly see many, many people with uncorrected low HDLs and other patterns.

Have a serious discussion and press for confident answers if you find your doctor reflexively telling you that the wart on your thumb should be blamed on niacin.

Here are the steps we advise that really make taking niacin easy and tolerable:

1) Take with dinner.

2) Take with 2 extra glasses of water. If you experience the hot-flush later on, drink an additional 2 8-12 oz glasses of water i.e., a total of 16-24 oz). Extra hydration is extremely effective for blocking the hot-flush.

3) Take a 325 mg, uncoated aspirin. This is only necessary in the beginning or with any increase in dose, rarely chronically for any length of time.

This is not to say that there aren't occasional people who are truly and genuinely intolerant to niacin. It does happen. But those people are a small minority, less than 5% of people in my experience. Niacin is far more effective and safe than most physicians would have you believe.

Eat fish three times a day

29. October 2006 William Davis (1)

Patients commonly ask, "Why can't I get vitamin D from food? I drink milk and eat fish."

They're absolutely right: both vitamin D and some oily fish contain vitamin D. However, it's a matter of quantity. An 8 oz. glass of milk contains 100 units of vitamin D (at least it's supposed to; this is not always true). A serving of oily fish like salmon or herring may contain up to 400 units. Thus, if you ate fish three times a day like the Eskimos or the Inuit, you might obtain sufficient vitamin D to prevent the broad and alarming spectrum of phenomena associated with deficiency.

I suspect that most people don't want to eat fish three times a day, nor drink the 20 to 50 glasses of milk per day that would be required to obtain a truly healthy quantity of vitamin D.

The vocal and outspoken Dr. John Cannell of the Vitamin D Council (www.vitamindcouncil.com) has written eloquently on the potential relationship between influenza and vitamin D deficiency. He and his co-authors on a recently published paper point out that the peculiar and unexplained seasonality of influenza corresponds to vitamin D levels. Read his eloquent discussion in Medical News Today at http://www.medicalnewstoday.com/medicalnews.php?newsid=51913.

In the article, Dr. Cannell explains:

"The vitamin D steroid hormone system has always had its origins in the skin, not in the mouth. Until quite recently, when dermatologists and governments began warning us about the dangers of sunlight, humans made enormous quantities of vitamin D where humans have always made it, where naked skin meets the ultraviolet B radiation of sunlight.

We just cannot get adequate amounts of vitamin D from our diet. If we don't expose ourselves to ultraviolet light, we must get vitamin D from dietary supplements...Today, most humans only make about a thousand units of vitamin D a day from sun exposure; many people, such as the elderly or African Americans, make much less than that. How much did humans normally make? A single, twenty-minute, full body exposure to summer sun will trigger the delivery of 20,000 units of vitamin D into the circulation of most people within 48 hours. Twenty thousand units, that's the single most important fact about vitamin D. Compare that to the 100 units you get from a glass of milk, or the several hundred daily units the U.S. government recommend as “Adequate Intake.” It's what we call an “order of magnitude” difference.

"Humans evolved naked in sub-equatorial Africa, where the sun shines directly overhead much of the year and where our species must have obtained tens of thousands of units of vitamin D every day, in spite of our skin developing heavy melanin concentrations (racial pigmentation) for protecting the deeper layers of the skin. Even after humans migrated to temperate latitudes, where our skin rapidly lightened to allow for more rapid vitamin D production, humans worked outdoors. However, in the last three hundred years, we began to work indoors; in the last one hundred years, we began to travel inside cars; in the last several decades, we began to lather on sunblock and consciously avoid sunlight. All of these things lower vitamin D blood levels. The inescapable conclusion is that vitamin D levels in modern humans are not just low - they are aberrantly low."

Like Dr. Cannell, I am absolutely convinced that vitamin D deficiency plays an important role in a number of illnesses, including coronary disease. The more we mind our patients/participants vitamin D status (blood levels of 25-OH-vitamin D3), the more easily we gain control over LDL cholesterol, pre-diabetic patterns, blood pressure, blood sugar, and coronary plaque. In fact, I am becoming rapidly convinced that vitamin D deficiency is an extremely important coronary risk factor.

Because I live in Wisconsin (bbrrrrr!) where seeing the sun is a cause for celebration and sun exposure is possible three months a year, I take 6000 units per day vitamin D. This is the amount necessary to raise my blood levels into the true, physiologic range of 50-70 ng/ml. My wife takes 2000 units per day, and each of my kids takes 1000 units per day, though I believe that my 14-year old son (my size now) should take more. We'll judge by blood levels.

If there is a little-known secret to reducing heart scan scores, vitamin D is that "secret".

What if I had a cure for coronary disease?

29. October 2006 William Davis (0)

If I had a cure for coronary disease, what would it look like? What would constitute cure? Would you recognize it if I showed it to you?

In the strictest sense, "cure" means an absolute elimination of any sign of coronary plaque, as well as elimination of any and all dangers associated with coronary disease. It would also mean elimination of the factors that created coronary atherosclerotic plaque in the first place.

In a more practical sense, you could argue that "cure" means a reduction of the amount of material that constitute coronary disease along with a dramatic reduction of the associated risks (i.e., heart attack).

You might call this second, more lax definition "regression" or "reversal".

Is "cure" in the strictest sense possible? No, not to my knowledge in 2006. Yes, there are many (kooks) who claim this is possible, but there's no objective evidence of this occurring.

Regression, or reversal, however, is indeed possible. In fact, I've seen it countless times following the participants in the Track Your Plaque program. If your heart scan score goes from 1000 (a bad score with high risk for heart attack) to 750, you've experienced a large reduction in the amount of atherosclerotic plaque that is behind coronary disease. You've also reduced your risk of an "event" like heart attack to near zero (provided you remain on the program that achieved regression in the first place).

Unfortunately, with present technology regression or reversal does not mean that the original causes of coornary plaque are eliminated. They're just controlled. Fish oil, for example, powerfully reduces triglyceride-containing lipoproteins that trigger coronary plaque growth. But if you stop fish oil, the evil lipoproteins come right back and start injuring your coronaries, causing more plaque growth.

Olive oil for gourmets

19. October 2006 William Davis (0)

"The finest extra-virgin olive oils should not be used as a medium for hot cooking, but rather as a condiment or a finisher on top of your favorite savory foods. They are expensive, but if stored properly they will last for up to a year..."

You all know that olive oil is among the preferred oils to use: rich in monounsaturates, low in saturates, high in polyphenols.

For a fascinating perspective for the olive oil gourmet, go to www.npr.org, the website for National Public Radio. (Scroll down to the article or enter olive oil into their site search.) Their article, "Like fine wines, fine olive oils boast subtle joys" provides an insightful discussion on squeezing maximum enjoyment out of this wonderful "functional food".

As we emerge from the mis-directed low-fat craze of the past 20 years, we're re-discovering the joys of healthy oils. You'll find some great thoughts here

Vitamin D must be oil-based

18. October 2006 William Davis (10)

As part of the Track Your Plaque coronary plaque reversal program, we advocate vitamin D supplementation. Vitamin D has been shown to reduce blood sugar and reduce pre-diabetic tendencies, reduce blood pressure (it's a renin antagonist, a blood pressure hormone), it's far more important for bone health than calcium, and it may help prevent colon cancer, prostate cancer, and multiple sclerosis.

And, oh yes, it may facilitate coronary plaque regression.

One lesson I've learned is that vitamin D MUST be taken as a oil-based capsule or gelcap. You'll recognize it as a transparent or translucent, sometimes opaque, capsule. The list of ingredients may say something like "cholecalciferol [vitamin D] in a base of soybean oil", indicating that the active ingredient is oil-based.

Oil-based vitamin D3 skyrockets blood levels of 25-OH-vitamin D3 in to the normal range reliably and easily.

Tablets are a different story. These are generally white powdery tablets. The rise in blood levels of vitamin D3 are minimal, sometimes none. Women will often say "I get vitamin D with my calcium tablets."

People taking this form almost always have blood levels of vitamin D that are low, as if they were taking nothing.
If you're going to take vitamin D, the oil-based tablets are the way to go. They're not necessarily any more expensive. We've had good experiences with the Nature's Life 2000 unit capsule, as well as preparations from Life Extension. We have had negative experiences with the preparations from GNC, Sam's Club, and Walgreen's, all tablets and non-oil-based.

When is LDL cholesterol NOT LDL cholesterol?

18. October 2006 William Davis (0)

Darlene had a high LDL cholesterol, at times as high as 200 mg/dl. Her primary care doctor first tried Mevacor, then Pravachol, then Zocor, then Lipitor. Every statin drug failed to reduce Darlene's LDL below 160 mg/dl, even when maximum doses were used. The higher doses also resulted in nearly intolerable muscle aches and weakness.

When we sent Darlene's blood sample off for lipoprotein analysis, a surprise came back: she had a high lipoprotein(a), or Lp(a). This explained a lot.

LDL cholesterol is not always just LDL cholesterol. One of the particles that can masquerade as LDL is Lp(a). Darlene's story is typical of many people who've had high cholesterol levels poorly responsive to the statin drugs. That's because their LDL conceals Lp(a), which does not respond to these agents. LDL cholesterol does drop some because there's also some real LDL mixed in.

A poor response to statin agents or to nutritional strategies to reduce LDL is a tip-off that Lp(a) may be hidden. The answer: just measure Lp(a)! If you and your doctor don't measure it, you won't know whether or not you have it. Rather than a statin drug, we put Darlen on niacin. Not only did her Lp(a) drop, but her LDL also plummeted.

What is a desirable triglyceride level?

17. October 2006 William Davis (0)

Though well-intended, the National Cholesterol Education Panel's Adult Treatment Panel, or ATP-III, (whew!) guidelines for cholesterol have been responsible for loads of misinformation.

The intention was to educate the internist or family doctor who treats sore throats, performs Pap smears, administers pneumovax vaccine, treats arthritic knees---and dabbles in heart disease prevention. The ATP-III guidelines are the "Cholesterol for Dummies" approach.

What standard guidelines definitely do not represent are the ideal values to achieve. They do not ensure protection from heart disease. This is particularly true of the ATP-III advice to keep triglycerides at or below the "desirable" level of 150 mg/dl.

In the Track Your Plaque program, we ask "What is necessary to tip the odds in favor of coronary plaque regresion or reduction of heart scan score?" This is not achieved with a triglyceride of 150. In fact, triglycerides at this level are associated with flagrant abnormalities of lipoprotein patterns. It usually means that processed carbohydrates, particularly wheat products, are occupying too prominent a role in your food choices. It could mean that you're making excessive use of processed foods containining high-fructose corn syrup. It will not respond to a low-fat diet. It will, however, respond vigorously to fish oil.

Triglycerides are a crucial aspect of your plaque control program. We aim for 60 mg/dl or less. The ideal level is actually 45 mg/dl. At this level, all abnormal triglyceride-containing lipoproteins finally go away.

Super size me in little bits and pieces

17. October 2006 William Davis (1)

Alvin came into the office for consultation on his cholesterol values: LDL 198 mg/dl, HDL, 43 mg/dl, triglycerides 143 mg/dl. He says that he doesn't really try to choose healthy foods but he restricts his overall calorie intake by following the Weight Watcher's exchange approach.

Every morning, 7 days a week, Alvin eats a Sausage McMuffin for breakfast. He justified this by skipping lunch to make up for the 450 calories in the Sausage McMuffin, and not eating anything until dinner.

Can this work? Can you eat foods with unhealthy ingredients but make up the excessive calories by cutting back elsewhere?

The nutritional composition of McDonald's Sausage McMuffin includes 27 grams of total fat (10 gm saturated); 255 mg cholesterol; 950 mg sodium; 31 gm carbohydrate; 2 grams fiber. In other words, it's essentially the same as butter with sugar on it--pure fat, processed wheat, with little fiber or nutritive value.

For Alvin, this is an extremely unhealthy way to eat. His lipid patterns are just the tip of the iceberg: multiple hidden factors are also at work to create heart disease, atherosclerosis in other territories outside the heart, diabetes, high blood pressure, and cancer.

I think the effects are not much different than what Morgan Spurlock achieved in his Super Size Me documentary, but in little bits and pieces. Eating at McDonald's "restaurants" three times a day yielded frightening changes in his lipids, liver function, kidney function, not to mention his appearance and the way he felt. Alvin is doing the same thing, though in less dramatic fashion.

I see this very frequently: people mimicking the experience of Spurlock, just a little at a time, with overindulgence in processed fats and starches.

When you seen a set of Mcdonald's golden arches (or any fast food restaurant, for that matter), run as fast as you can in the other direction. Such indulgences, even in small bits and pieces, still creates a mess of your health.

View from the precipice

15. October 2006 William Davis (0)

Many people, upon first learning of their CT heart scan score, feel like they're on the edge of a sharp drop. It can feel like you're facing a vast, unknown abyss. At the bottom, all those dreaded things that can happen to you: heart attack, heart failure, hospitals, even dying.

I've encountered this "deer in the headlights" look many times. It truly can be frightening to hear that your heart scan score is 300, or 500, or whatever.

What I find truly frightening, however, is when your score prompts the usual array of misinformation commonly dispensed by physicians: "That's so bad you need a heart catheterization", "Nobody knows why people get calcified plaque", or "Reversal is impossible". All absolute bunk.

Let your fear motivate you to do something about your risk for heart disease. Aim for reversal of your coronary plaque and seek out the tools to achieve this. It is possible and, in fact, we do it all the time. I can't claim 100% success, but the majority of people who engage in an effort like the Track Your Plaque program to reverse coronary plaque succeed. Even a substantial slowing of plaque growth from the expected 30% per year is better than submitting to the conventional approach.

At the very least, get both LDL and HDL cholesterol around 60 mg/dl. This alone is a major plus in reducing the risks associated with your heart scan score. It doesn't guaranteee reversal, but it sure tips the odds in your favor.

Organic Rice Krispies?

Breakfast cereal manufacturing giant, Kelloggs, is launching a line of three cereals that will carry the "organic" designation: Organic Rice Krispies, Organic Raisin Bran, and Organic Frosted Mini-Wheats.

This reminds me of the advertisements I've seen for "fresh fried chicken", or "fresh from the can", or "contains only pure cane sugar". How about organic tobacco? Would that make cigarettes healthier?

The TV ad ends with the slogan "Childood is calling!" Oh, those marketers are a shrewd, clever bunch. I worry that they're so clever that most people will fall for these ludicrous tricks.

Don't fall for these thinly-shrouded marketing shenanigans. Organic? Who cares. These foods remain unhealthy whether or not they contain pesticide residues. Take a look at the nutritional composition: Rice Krispies, organic or not, is sugar to your body. It is the sort of food that creates pre-diabetes, diabetes, makes us fat, and fans the flames of lipoprotein patterns like small LDL, VLDL, and postprandial particles, all of which is like throwing cow manure on the weed patch of your coronary plaque.

Nuts as functional foods

13. October 2006 William Davis (0)

Food manufacturers gave nuts a bad name when they started adding evil ingredients to them. "Party mix", "honey-roasted", mixed nuts, etc., are made with added hydrogenated oils, salt, sugar, excessive quantities of raisins, or other added ingredients that turned a healthy food--nuts--into something that made us fat and hypertensive, raised LDL, dropped HDL, and raised blood pressure.

But nuts themselves are, for the most part, very healthy foods. The very best are nuts with a brown fiber coating like almonds, walnuts, and pecans. Nearly all nuts also come rich in monounsaturated oils similar to that in olive oil. Although calorie-dense, nuts tend to be very filling and slash your appetite for other foods. I have never seen anyone gain weight by adding raw nuts to their diet. In fact, I find adding raw nuts cuts craving for sweets.

Nuts are also among the most concentrated sources of magnesium, containing around 150 mg per 1/2 cup serving. As most Americans are at least marginally if not severely deficient in magnesium, this really helps. Magnesium deficiency is a prominent aspect of "metabolic syndrome" and resistance to insulin.

Some nuts have added benefits like the l-arginine content of almonds or the linolenic acid content of walnuts. However, I think the real health "punch" comes from the fiber and monounsaturate content.

Add 1/4-1/2 cup of raw almonds, walnuts, or pecans per day to your diet and what can you expect? The effects that I see every day that are relevant to plaque control/heart scan score-reducing efforts include:

--Reduction in LDL--usually a 20 mg/dl drop, sometimes more.

--Reduction in triglycerides, especially if nuts replace processed carbohydrate calories. This may be because the fiber and monounsaturate content of nuts reduces blood sugar and the effective glycemic index of any accompanying foods.

--Modest blood pressure reduction.

--Though somewhat inconsistent, partial suppression of the dreaded small LDL particle pattern. We struggle with turning off the small LDL pattern in some people, and raw nuts can provide a real advantage.

If that isn't enough, the fiber content also makes your bowels regular.

Unless there's some reason to avoid nuts (e.g., allergy), nuts should be a part of your heart scan score reducing program. Shop around, as prices can vary wildly. I've been paying $12.99 for a 3 lb bag of raw almonds from Sam's Club, though I've seen almonds elsewhere for up to $12.99 per pound.

For additional commentary, go to one of my favorite Blogs, http://fanaticcook.blogspot.com. The Fanatic Cook's recent post, The Season for Walnuts , provides additional discussion on walnuts and the recent study showing how they improve "endothelial function". The nutritionist behind this Blog has fabulous insights into food, including the concept of "functional foods", i.e., using foods as a treatment tool. She is also unfailingly entertaining.

Can you tell the difference?

12. October 2006 William Davis (0)

Stan is 55 years old. He feels fine, is in moderately good physical condition. His LDL cholesterol is 135 mg/dl, HDL 43 mg/dl, triglycerides 167 mg/dl, total cholesterol 211 mg/dl.

Can you tell me whether Stan has heart disease or not?

How about Charles? Charles has an LDL cholesterol of 127 mg/dl, HDL of 44 mg/dl, triglycerides of 98 mg/dl, and total cholesterol of 191 mg/dl. He is also reasonably fit and feels fine. Can you tell whether Charles has heart disease?

If you can't, don't feel bad. Neither can your doctor. But this is the folly of using cholesterol for risk prediction.

Stan's heart scan score: 0

Charles' heart scan score: 978

Look even more closely at Stan's and Charles' cholesterol numbers. Is there some fine distinction we overlooked? What if we calculated total cholesterol to HDL ratio? Or LDL/HDL ratio?

No matter how you squeeze it, shake it, beat it with a stick, you simply cannot use cholesterol numbers to predict heart disease in specific individuals. Yes, the higher your LDL cholesterol and lower your HDL, the higehr your total cholesterol to HDL ratio, the greater the likelihood of heart disease. But you can simply cannot tell in a specific individual at a specific point in time. If you've seen your doctor puzzle over the numbers, understand that he/she is trying to make sense out of something that doesn't make sense, no matter how hard he/she tries.

You simply need to measure the disease itself: get a CT heart scan, the only measure of atherosclerotic coronary plaque that you have access to.

By the way, if you haven't seen it yet, go to the Track Your Plaque website (www.cureality.com) to see the news piece reporting the American Heart Association's much overdue position statement on CT heart scanning. The AHA has finally released a statement which, in effect, provides their "official" endorsement. Blocked by political shenanigans behind the scenes for several years, the guidelines finally made it to press. The only real difference it makes to me is that my patients may finally get their heart scans paid for by insurance, once the insurance companies realize that it's getting tougher and tougher to dodge their responsibility.

Statin agents and muscle aches

11. October 2006 William Davis (2)

How common are muscle aches with the statin drugs?

It depends on who you ask. If you ask the drug manufacturers, they will tell you no more than 2% of people who take them. They back this up with the experience in tens of thousands of people in published clinical trials.

What if we ask people who take them outside of clinical trials. How many then? I estimate, from my large experience, over 80%! In other words, muscle aches are inevitable in nearly everyone who takes them. The longer you take them, the higher your dose, the more likely muscle aches are going to be.

Why the disconnect between published data and real-world experience? I really don't know. In some instances, the differences are dramatic. The ASTEROID trial, for instance, in which Crestor, 40 mg, was given for two years, only resulted in 8% of people dropping out because of side-effects. My experience: everybody--nobody can tolerate this dose for any length of time.

Let me qualify what "muscle aches" mean. It means achiness and/or weakness, usually mild, occasionally moderate to severe, worse upon awakening and less with use. It can affect many muscles or it can involve only one. Rarely is it incapacitating but it is commonly annoying and frightening. It commonly shows up as gradually diminishing strength with exercise. Strength usually returns promptly upon stopping the offending drug.

"Rhabdomyolysis", or true muscle destruction is, fortunately, very unusual in otherwise well people. People with abnormal kidney function, diabetes, and other concurrent illnesses are somewhat more prone. But in reality, rhabdomyolysis is unusual. I've personally seen it twice, both in people sick for other reasons.

Coenzyme Q10 (CoQ10) supplementation has been a godsend for us. At least 4 out of 5 people who require statins and develop muscle aches respond favorably, but it requires 100 mg per day. The preparation must be oil-based to work, not powder in a capsule which exerts no effect. Some people get by with less; some require as much as 300 mg per day. I've had favorable experiences with the CoQ10 from Sam's Club, GNC, Vitamin Shoppe, and Life Extension (www.LEF.org).

The Track Your Plaque target for LDL cholesterol is 60 mg/dl. Many people do indeed use statins to achieve this level, the level of LDL that amplifies your chances of heart disease reversal, i.e., reduction of heart scan score. The only drawback that I'm aware of with CoQ10 replacement is cost. Beyond this, it's a benign supplement that even supplies higher energy for some people who take it.

American Heart Association stamp of approval

2. June 2007 William Davis (8)

The American Heart Association (AHA) has a program called the Heart-Check Mark, an "approval" process that permits a food manufacturer to affix the AHA logo and stamp of approval on various food products.

A company simply makes application to the AHA. The application and product details are reviewed and then approved or turned down.

To date, 106 companies have obtained the AHA stamp of approval on 768 products. What kinds of products are on the approved list? Here's a sample:

--Honey Bunches of Oats

--Kellogg's Frosted Mini-Wheats

--Cocoa Puffs cereal

--Cookie Crisp cereal ("The great taste of chocolate chips in every bite!")

There are 764 others. If you doubt this, just go to the store and take a look at the product containers.

What the heck is going on here? Most of us with any judgment know that these products are pure sugar. They may contain "no more" than 15-40 grams sugar per sugar, but the principal products--corn, wheat, fructose--mean that these products are, in effect, nearly pure sugar. Yet they carry the AHA stamp of approval.

What do products like this cause? It's a long list but the major effects include:

--Obesity

--Diabetes

--Drop in HDL

--Rise in triglycerides

--Small LDL particles

--Heightened inflammation (i.e., C-reactive protein)

--Mental cloudiness

Need I go on? Why are products like these and many others deserving of the AHA heart-check approval? Because they lack high fat and saturated fat (3.0 grams, 1.0 grams respectively, by AHA criteria). In other words, just lacking these ingredients means that, to the AHA, they qualify as "heart healthy."

By that same line of reasoning, many candy bars are "heart healthy", as are many cookies and cupcakes.

What's the reason behind this extraordinary absurdity? Is the AHA stupid?

There may be many reasons, but one very suspicious fact becomes immediately obvious when you realize these endorsements product a substantial revenue source for the AHA, since companies must pay for the right to use the heart-check approval mark. Also, just look at the major contributors (millions of dollars) to the AHA: ConAgra, General Mills, Kraft, etc.) You get the picture.

Does this make the AHA evil? Not necessarily. But it seriously erodes credibility. it also should make you very leery of any advice that comes from such an agency that is reluctant to bite the food manufacturer hands that feed it.

In my view, we simply cannot rely on the AHA for genuine, unbiased heart health advice.

"Your heart scan score means nothing"

1. June 2007 William Davis (7)

Charles was visibly confused.

He'd gotten his CT heart scan after hearing one of the local scan center's ads on the radio. His score 2773, obviously in the 99th percentile for any age.

"Do you think the score means anything? My primary doctor said that it was meaningless because it was all in the deep wall of the artery. He said that it has nothing to do with risk for heart attack. As long as I feel good, he says don't do anything."

What exactly did his doctor mean, in the "deep wall of the artery"?

What the doctor is referring to is the fact that some people with a long history (many years) of diabetes or kidney failure (also for many years) tend to develop calcium deposits in the media, or muscular layer of arteries. The media is the tissue thin layer just below the intima, the most inner layer of arteries that we usually associate with atherosclerotic plaque and the layer that is most prone to calcium accumulation that we score on heart scans.

Aging, generally into your late 70s, 80s, and onwards, also increases the likelihood of medial calcification. Lastly, longstanding deficiency of vitamin D encourages medial calcification.

Is there any way to distinguish intimal vs medial calcification on a heart scan? No, there is not. Having read many thousands of CT heart scans, I can tell you that there is no practical way in 2007 to tell the difference.

Then how did this doctor "know" that Charles' calcium was "deep walled" or medial? Simple: He didn't. This was yet another example of ignorance based on old thinking. Unfortunately, he did Charles a serious disservice by dismissing his heart scan score that predicted a 25% per year risk for heart attack.

Interestingly, whether calcium is intimal as in atherosclerotic plaque, or medial, both are strongly associated with risk for heart attack. In other words, if calcium is confined to the intima, heart disease risk is present. If calcium is limited to the media, risk is still present.

In all practicality, the only difference we make of the intima vs. media argument (that is, when the distinction has been made by some other means like intracoronary ultrasound, the test that is truly necessary to distinguish the two patterns) is that medial calcification may be more powerfully related to vitamin D deficiency. Thus, someone with heavy medial calcification may require closer attention to maintaining a perfect year-round blood level of 25-OH-vitamin D3. But that's the only practical difference.

Vitamin D toxicity?

30. May 2007 William Davis (3)

"My primary care doctor said to stop the vitamin D because it's toxic. So I stopped it and I just take a multivitamin. He said that a multivitamin and two glasses of milk a day was all I needed."

So proclaimed Eleanor to me. This happens around once every week by doctors frightened of the vitamin D.

So I reminded Eleanor that, before starting vitamin D supplementation, her blood level of 25-OH-vitamin D3 had been 17 ng/ml--severe deficiency.

On 4000 units per day (oil-based gelcap), her blood level had been 37 ng/ml--still deficient, below the desirable range of 50-60 ng/ml. That's the dose Eleanor's doctor had declared "toxic."

When exactly does deficiency develop? There's not full agreement on this, but Dr. Michael Holick of Boston University, among the most experienced and insightful authorities on vitamin D, states that toxicity is more likely when blood levels exceed 150 ng/ml (Nutr Clin Pract. 2007 Jun;22(3):297-304).

In other words, Eleanor and her doctor should not be concerned with toxicity, but with the persistent levels of deficiency she is suffering.

Some authorities call the behavior of vitamin D "bi-phasic": Deficiency is toxic, excessive levels are toxic. We're really just trying to achieve a middle ground in vitamin D levels that are above deficiency but below toxicity.

In reality, deficiency is exceptionally common. In fact, it's the rule around here (northern U.S.), with >95% of everybody we check severely deficient in winter, mildly-moderately deficient in summer. Very few people approach normal levels year round without supplementation.

Toxicity, on the other hand, is exceedingly rare. I have seen it once in a woman who was taking a toxic dose of 50,000 units a day on the instructions of her (mis-guided) doctor. Thankfully, no ill-effects developed from this little "experiment."

So, it's not toxicity that is the overwhelmingly common worry, but deficiency, severe and sustained.

Non-profit hospitals

30. May 2007 William Davis (0)

Take a look at your local hospital and you're likely to notice several curious things:

1) It is likely non-profit, meaning it enjoys a non-profit status with the Internal Revenue Service and enjoys the tax benefits of not paying taxes on profits. This provides an advantage to tax-protected hospitals. 70% or more of hospitals in the U.S. are "non-profit."

2) Non-profit or no, many hospitals operate under the guise of a religious affiliation, e.g., St. Mary's Hospital, Trinity Hospital, All Saints', Jewish Hospital, etc.

3) Executives in non-profit hospitals can make capitalistic salaries. One CEO of a Milwaukee hospital took home $3.7 million dollars in salary last year. That's not including the very substantial perks and business interests in the spin-off businesses the hospital owns, including pharmacies, drug and medical device disitributors, even a venture capital division. "Non-profit" does not have to mean that executives within the operation can't benefit handsomely.

That same hospital system spends over $10 million dollars in a year in local marketing for TV ads, print advertising, etc. Ads are slick and professionally produced.

Make no bones about it: These are "non-profit" for tax purposes only . They are for-profit in every other sense of the phrase, including rich rewards for the insiders.

Guess how those fat executive salaries and large marketing budgets are paid for? That's right: the 12-inch incision in your chest; the four stents, defibrillator, and repeated nuclear stress tests; the revolving door of hospitalization after hospitalization that typifies the "heart patient" experience.

See the hospital for what it is: In the 21st century, it is no longer a charitable operation worthy of your volunteer time and donations. It is a business no different than Home Depot, IBM, or--Enron. Yes, they do perform needed services, as well. But the perverse equation that often determines who needs hospitalization and who doesn't, who needs a heart procedure and who doesn't, is not always based on necessity but on financial return. Just ask the CEO.

What's the best lipoprotein test?

29. May 2007 William Davis (5)

This is a frequent question from Track Your Plaque Members and others interested in improving their heart disease prevention program beyond that of simple-minded cholesterol testing.

I obtain lipoprotein testing every day on patients. I can tell you with the confidence of having done thousands of these tests that plain, old-fashioned cholesterol testing is like relying on riding a scooter to work compared to an 8-cylinder modern automobile. The scooter might get you there, but any rain, snow, or long distance to travel and you can just forget it.

All too often, lipoprotein testing uncovers abnormalities that standard cholesterol testing simply fails to uncover.

So, among the various lipoprotein tests available, which is best?

There are three commercial tests available today:

1) Gel electropheresis (GGE)--often known by its "brand" name as the Berkeley lipoprotein profile, after Berkeley HeartLabs. GGE uses a gel with an electric field applied to cause lipoproteins to migrate, based on particle size and charge.

2) Vertical auto-profile (VAP)--a form of centrifugation, or high-speed spinning of blood plasma to separate lipoprotein particles.

3) Nuclear magnetic resonance (NMR)--the idea of putting plasma in an NMR (also known as MRI) device to characterize blood proteins.

All three tests do an excellent job. All are competitively priced. All have validating data--lots of it--to justify their broad use (though health insurers, in their vast wisdom, would still have you believe that the tests are "experimental").

But is one better?

Having done many of all three (though least of VAP), I am partial to Liposcience's NMR. (By the way, I receive no fees from Liposcience to use their test, nor to promote it in any way.)

I believe NMR is superior in a few ways:

1) I believe that the LDL particle number is the best way to truly quantify LDL, better than apoprotein B and "direct" LDL.

2) It provides what I believe to be more accurate small LDL measures.

3) It provides intermediate-density lipoprotein (IDL), a post-prandial, or after-eating, measure not available on the other two.

Perhaps I'm biased because I use the NMR most frequently. But I've used it because I felt it yielded superior, more clinically believable, data.

In truth, all three laboratories do an excellent job and you'd be served fine by obtaining any of the three. But my heart goes to NMR.

Vitamin K2, aspirin, fish oil and blood thinning

27. May 2007 William Davis (12)

An interesting question came up from one of our Track Your Plaque Members on the Forum.

"I am now taking 9 mg of vitamin K1 and 1000 mcg of K2.

Does taking this supplement with this much K1 have a counteracting effect on the thinning/anticlotting properties of aspirin and fish oil that I also take?"

Great question (along with lots of other greater discussions we have on the Forum.)

The answer: Vitamin K should have no effect on the platelet-blocking effects of aspirin or fish oil. The majority of blood clot inhibiting effects of aspirin and fish oil arise from their ability to keep blood platelets from "clumping" (just like the TV commercials for Plavix).

Vitamin K, on the other hand, participates in the liver production of blood clotting factors (like II, VII, IX, and X, among others for you curious ones).

Thus, vitamin K-dependent clotting factors and platelet-blocking are two separate pathways to forming blood clots. Some of us refer to the difference as "red clots" from the vitamin K pathway and "white clots" from the platelet pathway, since they really do have this different physical appearance.

The vitamin K2 conversation, like that about vitamin D, is fascinating for its potential to provide the missing link between the tightly-tied fortunes of bone health and atherosclerosis. Why is someone with a high CT heart scan score far more likely to have osteoporosis? Vitamin D and K2 deficiency may provide the missing link for many people.

Jogging does NOT cause heart disease

14. June 2009 William Davis (20)

Periodically, I'll come across a knuckleheaded report like this one from Minneapolis:

Marathon Man’s Heart Damaged by Running?

Of course, the obligatory story about how a cardiologist came to the rescue and "saved his life" with a stent follows. In other words, a stent purportedly saved the life of this vigorous man with no symptoms and high capacity for exercise.

Does vigorous exercise, whether it's marathon running, long-distance biking, or triathlons, cause coronary disease? Should all vigorous athletes run to their doctor to see if they, too, need their lives to be "saved."

Let me tell you what's really going on here. People with the genetic pattern lipoprotein(a), or Lp(a), tend to be slender, intelligent and athletic. For genetic reasons, these people gravitate towards endurance sports like long-distance running. Lp(a) is a high-risk factor for coronary disease. It is the abnormality present in the majority of slender, healthy people who are shocked when they receive a high heart scan score or have a heart attack or receive a stent. (I call Lp(a) "the most aggressive known coronary risk factor that nobody's heard about.")

The association between endurance exercise and heart disease is just that: an association. It does not mean that exercise is causal. Having seen coronary plaque detected with heart scans in many runners, virtually all of whom demonstrated increased Lp(a), I believe that Lp(a) is causal.

Unfortunately, the man in the Minneapolis story, now that his life is "saved," will likely be advised to take a statin drug and follow a low-fat diet . . . you know, the diet that increases Lp(a).

Track Your Plaque and non-commercialism

29. April 2007 William Davis (6)

If you're a Track Your Plaque Member or viewer, you may know that we have resisted outside commercial involvement. We do not run advertising on the site, we do not allow drug companies to post ads, we do not covertly sponsor supplements. We do this to main the unbiased content of the site.

We've seen too many sites be tempted by the money offered by a drug company only to see content gradually drift towards providing nothing more than cleverly concealed drug advertising. I personally find this deceptive and disgusting. Ads are ads and everyone knows it. But when you subvert content, secretly driven by a commercial agenda, that I find abhorrent.

That said, however, I do wonder if we need the participation of some outside commercial interests to help our members. In other words, many (over half) of the questions and conversations we have with people is about what supplement to take, or what medication to take. While we cannot offer direct medical advice online (nor should we) because of legal and ethical restrictions, I wonder if could facilitate access to products.

Many people struggle, for instance, with trusted sources for l-arginine, vitamin D, fish oil. Other people struggle with finding a heart scan center because of the changing landscape of the CT scanning industry. Could we somehow provide a clear-cut segment of the website that clearly demarcates what is commercial and non-Track Your Plaque-originated, yet at least provides a starting place for more info?

Ideally, we would have personally tried and investigated everything there is out there applicable to the program. But that's simply impossible at this stage.

I feel strongly that we will never run conventional ads on the site. Nor will we ever permit any outside commercial interest to dictate what and how we say something. The internet world is full of places like that. Look at WebMD. I find the site embarassing in the degree of commercial bias there. We will NEVER sell out like that, regardless of the temptation. People with heart disease are all conducting a war with the commercial forces working to profit from them--hospitals, cardiologists, drug companies, medical device companies (yes, even they advertise to the public, e.g., implantable defibrillators--no kidding). Genuine, honest, unbiased information is sorely needed and not from some kook who either knows nothing about real people with real disease, or has a hidden agenda like selling you chelation.

I'd welcome any feedback either through this Blog or through the contact@cureality.com.

The nattokinase scam

28. April 2007 William Davis (179)

A conversation about vitamin K2 commonly leads to confusion. Several people have asked about something called nattokinase.

The scientific data on the potential role of vitamin K2 deficiency in causing both osteoporosis and vascular calcification is fascinating. Along with vitamin D3, vitamin K2 may be an important factor in regulation of calcium metabolism. Supplementation may prove to be a major strategy for inhibition of vascular calcification.

Obtaining K2 in the diet is tricky, since it's present in just a handful of foods: egg yolks, liver, traditional cheeses, and natto. This is where the confusion starts.

Natto is a Japanese fermented soy product. I've had it and it's quite disgusting. Nonetheless, Japanese who eat natto experience less fracture. (A parallel study in heart disease has not been performed.) Natto is also a source of another substance called nattokinase.

Advocates (otherwise often known as supplement distributors) claim that nattokinase is a "fibrinolytic", or blood clot-dissolving, preparation that "improves blood flow, protects from blood clots, and prevents heart attacks and strokes."

Don't you believe it. This is patent nonsense. There are several problems with this rationale:

--Any oral fibrinolytic agent is promptly degraded in the highly acid environment of the stomach. That's why all medically used fibrinolytics are given intravenously. Drug companies have struggled for years to encapsulate, modify, or somehow protect protein (or polypeptide) products taken orally from degrading this way. They've never succeeded. That's why, for instance, growth hormone (a polypeptide) remains an injection, not an oral agent. An oral growth hormone, by the way, would sell like mad, so the drug companies would very much like to figure out how to bypass the degradative effects of stomach acid. One of the "researchers" behind the nattokinase claims boasts that he has single-handedly figured out how to protect the nattokinase molecule in the gastrointestinal tract. However, he won't tell anybody how he does it. Right.

--Fibrinolytic agents are extremely dangerous. In years past, we used to treat heart attacks with intravenous fibrinolytic agents like tissue plasminogen activator, urokinase, streptokinase, and others. They have fallen by the wayside, for the most part, because of limited effectiveness and the unavoidable dangers of their use. Fibrinolytics are "dumb": they dissolve blood clots in both good places and bad. While they might dissolve the blood clot causing your heart attack, they also degrade the tiny clot in your cerebral (brain) circulation that was protective. That's why fatal brain hemorrhages, bleeding stomach ulcers, and blood oozing from strange places can also occur with fibrinolytic administration. Believe me, I've seen it happen, and I've watched people die from them.

The idea that a small dose taken orally is healthy is ridiculous. Even if nattokinase worked, why the heck would you take an agent that has known dangerous and very real consequences?

Don't let this idiocy reflect poorly on the K2 conversation, which, I believe, holds real merit and is backed by legitimate science. This is symptomatic of a larger difficulty with the supplement industry: Insane and unfounded claims about one supplement erodes credibility for the entire industry. It gives regulation-crazed people like the FDA ammunition to go after supplements, something none of us need. You and I have to sift through the nonsense to uncover the real gems in this rockpile, real gems like vitamin D3, omega-3 fatty acids from fish oil, and, perhaps, vitamin K2. But not nattokinase.

Blood pressure with exercise

27. April 2007 William Davis (10)

Here's a frequently neglected cause for an increasing CT heart scan score: High blood pressure with exercise. Let me explain.

Paul's blood pressure at rest, sitting in the office or on arising in the morning, or at other relatively peaceful moments: 110/75 to 130/80--all in the conventional normal range.

We put Paul on the treadmill for a stress test. At 10 mets of effort (on the protocol used, this means 3.4 mph treadmill speed at 14 degree incline), Paul's blood pressure skyrockets to 220/105. That's really high.

Now, blood pressure is expected to increase with exercise. If it doesn't rise, that's abnormal and may, in fact, be a sign of danger. Normally, blood pressure should rise gradually in a stepwise fashion with increasing levels of exercise. But any blood pressure exceeding 170/90 is clearly too high with exercise. (Not to be confused with high blood pressures not involving exercise.) A handful of studies have suggested that a "breakpoint" of 170/90 also predicts heightened risk of heart attack over a long period.)

I see this phenomenon frequently--normal blood pressure at rest, high with exercise. This also suggests that when Paul is stressed, upset, in traffic congestion, under pressure at work, etc., his blood pressure is high during those periods, as well. I wouldn't be surprised to see other phenomena of underappreciated high blood pressure, like abnormally thick heart muscle (left ventricular hypertrophy), an enlarged thoracic aorta (visible on your heart scan), left atrium, perhaps even an abnormal EKG or abnormal kidney function (evidenced by an elevated creatinine on a standard blood panel).

Unfortunately, the treatments that reduce blood pressure are "stupid," i.e., they have no appreciation for what you are doing and they reduce blood pressure all the time, whether or not you're stressed, exercising, or sleeping.

Blood pressure reduction should begin with weight loss, exercise, reduction of saturated fats and processed carbohydrates (esp. wheat), magnesium replacement, vitamin D replacement. Think about CoQ10. After this, blood pressure medication might be necessary.

The message: Watch out for the blood pressures when you have a stress test. Or, if you have a friend who is adept at getting blood pressures, get a blood pressure immediately upon ceasing exercise. It should be no higher than 170/90.

Vitamin D2 vs. vitamin D3

26. April 2007 William Davis (21)

An interesting question came up on the Track Your Plaque Member Forum about vitamin D2 vs. vitamin D3. This often comes up among our patients, as well.

Vitamin D is measured in the blood as 25-OH-vitamin D and is distinct from 1,25-diOH-vitamin D, a kidney measure, a test you do not need unless you have kidney failure.

The human form of vitamin D is cholecalciferol and is usually obtained via activation of a precursor molecule in the skin on activation by the sun. You can also take cholecalciferol and it increases blood levels of 25-hydroxy vitamin D reliably.

However, there is a cheap, plant-sourced, alternative to vitamin D3, called vitamin D2, or ergocalciferol. D2 has far less effect in the body. Taking D2 or ergocalciferol orally is an extremely inefficient way to get D. Unfortunately, it's the form often used in milk and many supplements, even the prescription form of D. About half the multivitamins and calcium supplements I've looked at contain ergocalciferol rather than cholecalciferol.

Taking vitamin D2 yields very little conversion to the effective D3. This particular issues is maddening, as the USDA requires dairy farmers to add 100 units of vitamin D to milk, and D2 is often used. In other words, the D in many dairy products barely works at all. There are many children who rely on D from dairy products who are at risk for rickets and are not getting the D they need from dairy products because of this cost-saving switch. Do not rely on milk for vitamin D for your children.

D2 or ergocalciferol is often included in the blood measures of vitamin D along with vitamin D3. The only reason it's checked with blood work is to ensure "compliance,", i.e., see whether or not you're taking a prescribed ergocalciferol. Beyond this, it has no usefulness.

25-OH-vitamin D3, or cholecalciferol, is both the blood measure and the supplement you need. This is the one that packs all the punch. Keep in mind also that it is the oil-based gelcap you want, with more consistent and efficient absorption. Tablets usually barely work at all, even if it contains cholecalciferol. Most people who take calcium tablets with D, or multivitamin with D, not only are getting a powdered form of D, but also in trivial doses. It's the pure vitamin D3, cholecalciferol, in gelcap form you want if you desire all the spectacular benefits of vitamin D.

A quick but important note.

Track Your Plaque Members:

Keep your eyes on the Track Your Plaque Member website for details and images of our most recent huge success story. Track Your Plaque participant, Neal, dropped his score more than anyone else before.

Although reduction of heart scan score is an everyday event around here, a 51% drop in score deserves to make news!

We will post the images of Neal's heart scans on the www.cureality.com Member website in the coming days.

Dose of fish oil

26. April 2007 William Davis (2)

Dosing for fish oil is a perennial point of confusion. However, it's quite simple.

The active ingredients in fish oil are DHA and EPA, the so-called omega-3 fatty acids. Of course, if there's anything else in your capsules, such as omega-6, omega-9, or linolenic acid, these should not count towards the sum of EPA + DHA, since they do not exert the same benefits as the omega-3s.

The basic suggested starting dose for the Track Your Plaque program is 1200 mg of EPA+DHA. This is usually provided by taking 4 x 1000 mg capsules of fish oil, providing 180 mg EPA, 120 mg DHA per capsules, for a total of 1200 mg EPA+DHA.

About a third of people, however, will require greater doses of omega-3s to reduce triglycerides, VLDL, and/or intermediate-density lipoprotein (IDL). Most people will do fine with an increase to 1800 mg EPA+DHA, usually provided by 6 x 1000 mg standard capsules. A very occasional person (about 1 in 100) will require even higher doses.

If you ever decide to change your fish oil preparation, or if you change to a more concentrated form or another form such as liquid fish oil (e.g., Carlson's), paste (e.g., Coromega), or syrup (e.g., Pharmax Frutol), then you will need to examine the label to determine the dose of EPA+DHA. If, for instance, a teaspoon of liquid fish oil provides 360 mg EPA and 240 mg DHA, that's a total of 600 mg omega-3s per teaspoon. If your EPA+DHA dose is 1200 mg per day, then two teaspoons a day should provide it. Always adding up the EPA+DHA content of whatever preparation you choose will therefore allow you to mix, match, or change your dose whenever you like.

Niacin scams

24. April 2007 William Davis (11)

As most of you know, niacin (vitamin B3) is an important tool for many in the Track Your Plaque program.

Niacin:

--raises HDL cholesterol
--reduces small LDL
--reduces lipoprotein(a)

And it's the most potent agent we have for all three patterns, despite just being a vitamin. Niacin also reduces LDL cholesterol, VLDL, IDL, triglycerides; reduces heart attack risk dramatically either alone or in combination with other agents.

Unfortunately, some people who are either afraid of the "hot flush" side effect, or experience excessive degrees of it, have resorted to two preparations sold in stores that have none of these effects.

Most notorious is "No-flush" niacin, also known as inositol hexaniacinate. This compound is an inositol sugar molecule complexed with 6 ("hexa-") niacin molecules. Unfortunately, it exerts none of niacin's effects in the human body. No-flush niacin has no effect on HDL, small LDL, or Lp(a), nor on LDL or heart attack.

In short, no-flush niacin is a scam. It's also not cheap. I've met people who have spent hundreds of dollars on this agent before they realize that nothing is happening, including a flush.

Likewise, nicotinamide does not work. It sounds awfully close to the other name for niacin, nicotinic acid. But they are two different things. Like no-flush niacin, nicotinamide has no effect on HDL, small LDL, Lp(a), etc.

Though I've discussed this issue in past, somehow these two "supplements" seem to sneak back into people's consciousness. You walk down the health food store aisle and spy that bottle of X-brand No-flush niacin, promising all the benefits of niacin with none of the bother. Then you remember that rough night you spent a few months back when the hot flush lasted longer than usual. That's when some people end up buying this agent making extravagant--and false--promises.

For now, for all its imperfections, niacin is still a pretty darn good agent for these patterns. Remember that the best strategy to minimize the hot flush effect is to drink plenty of water. We generally recommend taking the dose at dinner along with water. If the hot flush occurs, drink two large glasses of water (total volume 16-24 oz). Nine times out of ten, the flush is gone. It also dissipates the longer you take niacin.

Media mis-information

21. April 2007 William Davis (2)

This is an excerpt from a popular health website, EverydayHealth.com:

A Cholesterol-Busting Vitamin?
Did you know that niacin, one of the B vitamins, is also a potent cholesterol fighter? Find out how niacin can help reduce cholesterol…

Niacin is safe — except in people with chronic liver disease or certain other conditions, including diabetes and peptic ulcer. It is also inexpensive. However, it has numerous side effects. It can cause rashes and aggravate gout, diabetes, or peptic ulcers. Early in therapy, it can cause facial flushing for several minutes soon after a dose, although this response often stops after about two weeks of therapy and can be reduced by taking aspirin or ibuprofen half an hour before taking the niacin. A sustained-release preparation of niacin (Niaspan) appears to have fewer side effects, but may cause more liver function abnormalities, especially when combined with a statin.

Many people begin treatment at low doses (250 mg twice a day, for example) and, over six weeks or so, gradually build up to an amount that lowers lipid levels, anywhere from 1,000 to 2,500 mg split between two doses during the day. This gradual approach may help build tolerance to side effects such as facial flushing. Although niacin is available over the counter, you should not use it in quantities sufficient to lower cholesterol without a physician’s supervision. It is important to test liver function and levels of blood sugar and uric acid before beginning niacin therapy and during the course of treatment.

(Bold emphasis mine.)

At http://www.everydayhealth.com/publicsite/index.aspx?puid=548e8630-32d6-41dd-91a7-48e1cbac65ad&p=4

After an enticing headline, the article goes on to scare the pants off you. It also sounds like accurate information, delivered in an unbiased way, cold and straight.

If we were to use niacin this way, it would indeed be intolerable for most. Do not follow the above nonsensical advice. But that may have been the intention from the start.

Very telling are the fact that, both above and below the article were colorful advertisements for Lipitor, complete with Dr. Robert Jarvik’s (inventor of an implantable mechanical heart) soothing, professorial image.

Did they want to bait us with promising information about cholesterol and niacin, only to throw water on our fire and steer us towards something else?

That would be typical drug company marketing.

All in all, I’m grateful for the attention the media provides for health issues. Perhaps many people wouldn’t even be aware of niacin and other healthy strategies if some website, newspaper, or magazine article hadn’t talked about it.

But I do worry about bias. Was this an unbiased report? Or was it more like much of the physician-directed mail I receive, cleverly concealed propaganda from the drug manufacturers? Who wrote it? No author is listed. Could it have been ghost written by someone in the drug company itself, or an arm of the drug company? That’s a very common practice for the literature physicians receive, glossy, high-class materials paid for by drug companies, written by drug company-owned companies, but no company logo or name listed.

My point: Be skeptical of what the media tells us. There’s usually a good deal of truth in the reporting, but there’s also often just enough mis-information or slanting of content to make you behave or believe a certain way. “If niacin is this dangerous, maybe I really should take the Lipitor.”

A dirty little secret

21. April 2007 William Davis (0)

Here's a dirty little secret many people don't know about.

If I implant a stent, I might get paid somewhere around $2000 for the heart catheterization, stent implantation, femoral artery closure device, hospitalization charges. That's not too bad.

But what if I'd like more? What if I'd like to squeeze this unsuspecting patient for more, or actually his/her insurance company?

Easy: Add on complex procedures to the basic procedure that yield more professional charges. For instance, I could perform laser angioplasty, a procedure that adds another couple thousand dollars. I might pull out the old rotational atherectomy device, a high-speed diamond tipped drill that also adds substantial professional charges. I might also use the intracoronary ultrasound device, an otherwise helpful device, but I might pull it out to use on everybody.

With the exception of ultrasound, all the "add-on" procedures were more popular in the early and mid-1990s--before they were shown in clinical studies to provide no advantage, perhaps even add to procedural risks.

Thus, a patient might undergo a heart catheterization, balloon angioplasty with stent implantation into the proximal left anterior descending coronary artery (LAD), followed by laser angioplasty of the mid-LAD, followed by intracoronary ultrasound of the vessel. Next, rotational atherectomy of the circumflex, followed by stent and ultrasound. Total charges for this 2-3 hour procedure? Somewhere around $8000 to the cardiologist. Of course, hospital charges are far more.

Ironically, patients are invariably impressed. Hearing that they went through all sort of high-tech procedures makes them grateful for receiving the benefits of the skills of their cardiologist. Of course, they would like have done as well with a far simpler procedure. Perhaps they didn't need the procedure at all.

If the excessive use of procedures and devices fails to benefit patients, why don't hospitals discourage it? Two reasons: 1) It's difficult to legislate or regulate decisions made on judgement, which can be a tough issue with many fuzzy edges, and 2) hospitals made oodles more money from the practice.

If you have a salesman in your new car lot and he outsells all his colleagues by 30-50% and makes you a couple hundred thousand a month more in sales. You've watched him at work and he's clearly good at it. But you suspect that he pushes the envelope of propriety frequently--badgering customers, add rustproofing to a little grandmother's car that will be driven 3000 miles a year, selling cars for prices far above what they would have sold for had the customer bargained more vigorously.
do you put a stop to it at the risk of pushing your star salesman away? Few would.

Only a minority of my colleagues are guilty of this despicable practice. I only know of a few who openly do it. Hopefully, you're not among their patients.

The party’s over

21. April 2007 William Davis (0)

A good number of cardiology colleagues are vigorously bashing the outcome of the COURAGE Trial. Recall that COURAGE is the large clinical trial recently released that showed that, in people with stable angina (chest pains), people did equally well with “optimal medical therapy” as with stents.

The problem is that many of my colleagues wouldn’t know what to do in a world deprived of implanting 10 stents a day. Giving people nitroglycerin/statin drug/aspirin/beta-blocker day after day, week after week, would be an awfully dull world. All the excitement of the cath lab would be a lot more rare. We’d actually have to wait for a heart attack from some dumb smoker! All the money would disappear, too. After all, seeing a patient in the office pays, at best, $200 (and has to be stretched to cover overhead expenses like staff, malpractice insurance, and rent). Putting a stent in can pay $2000, $3000, $4000, often more. Put in several a day and—Wow! Now we’re talking money.

You can understand how upsetting it is to my colleagues who feel like the rug may be pulled out from underneath their practices and lives. Feel as sorry for them as you do for people who lose their jobs on an assembly line because of robotic technology. Or travel agents because everyone makes travel arrangements over the internet. Technology, in this information technology, marches on.

Cardiologists, cath labs, stent manufacturers, and the huge industry built around heart disease had their party. Now it’s time to clean the room and sober up. The party’s over.

The broader acceptance of “optimal medical therapy,” as lame as it is, will eventually open the door for many to demand for something even better. Ever hear of Track Your Plaque?
