Protecting the right to use bio-identical hormones in your heart disease prevention program

If you've been following the Track Your Plaque program, you know that we are advocates of "bio-identical hormones", i.e., hormone replacement using forms that are identical to the naturally-occuring human form.

In other words, we find it criminal that pharmaceutical manufacturers continue to promote use of non-identical hormones despite a probable increased side-effect and complication profile (a la Premarin). This unhappy situation persists because bio-identical hormones cannot be patent protected, meaning profits cannot be protected. Synthetic hormones can be patented and profits protected, thus their popularity among drug companies.

If that's not bad enough, Wyeth Pharmaceuticals--maker of synthetic hormone preparations, Premarin and Prempro--has filed an FDA petition to disallow the use of bio-identical hormones as prepared and dispensed by "compounding pharmacies". These are specialty pharmacies that mix and dispense hormones like estrogens (human estradiol, estriol, and estrione) and testosterone. They do so only with a doctor's prescription. Most are members of the Professional Compounding Centers of America (www.pccarx.com), a professional organization devoted to promoting quality-control over compounding practices.

Compounding pharmacies are occasionally guilty of compounding some suspect preparations. Witness the Fentanyl lollipops of 2002 in which the pain medication, Fentanyl, was put into lollipops for patients with chronic pain. This posed obvious dangers to any children who unsuspectingly ate the lollipops.

But the majority of compounding pharmacies are not guilty of such exotic practices. Most are simply pharmacies who might, for instance, mix a specific dermatologic preparation according to the orders of a dermatologist. Likewise with bio-identical hormones.

We have extensive experience with such a pharmacy in Madison, Wisconsin, the Women's International Pharmacy. They have filled hundreds of hormone prescription for us. They are responsible in their dispensing practices, in our experience. In fact, they have been at least as good, if not better, than other pharmacies we've dealt with.

We believe in protecting our rights to prescribe and you to use the choice of hormone preparations you and your doctor desire. This should include bio-identical hormones. The transparent profit motive from Wyeth should raise the hairs on your neck.

If you would like to post your comment to the FDA, there's a little time left. The folks at Womens' International Pharmacy have made it easy by posting links on their website. Go to http://www.womensinternational.com and just follow the instructions.



Here's a sample of some of the objections citizens have raised to Wyeth's petition:


I have been taking bioidentical hormones for two years. Bioidentical Hormones have been a great relief to me without the risk. I consult with my Physician who prescribes bio-identical hormones specifically for me, and my pharmacist prepares them. Without this medication and I would not be able to sleep; I would not be able to work due to the constant hot flashes. Without this medication, I find that I have less tolerance and I am considerably disagreeable. I also have problem with my memory without them. I want the bioidentcial hormones for the health benefits they provide. I urge you to not be swayed by Wyeth's petition. The product Premarin made by Wyeth, is made from pregnant horses not natural sources. Wyeth's hormones have been shown to cause cancer. I would not expect my government and its officials to submit to the highly funded petitioning of a pharmaceutical company who product is threatened by bioidentcial hormones. I do not expect my government to approved Wyeth's petition and leave me no choice of bioidentcial hormones and only the choice of Wyeth's cancer causing drugs Preamrin and Prempro. I ask that the FDA reject Wyeth's petition Docket #2005P-0411.

Another petitioner writes:

As a woman I take exception to Wyeth accusing the Compounding Pharmacy industry of unsafe practices. As a citizen of the United States I expect the FDA to stand up for my rights and the rights of all women who have found or in the future may seek consistent, safe and effective treatment with bioidentical hormones. Eliminating options by bowing to a large pharmaceutical company like Wyeth is not in the public interest and would deprive hundreds of thousands of American women from access to bioidentical hormones. Synthetic hormone replacement has been proven unequivocally unsafe in a government sponsored study and should not be forced as the sole treatment option for women. I hereby request the FDA rule against Wyeth's request. The FDA should not close down the bioidentical option of healthcare. I welcome studies of bioidentical hormones even though they are already FDA-approved and have been working effectively for decades. We already have the proof - hundreds of thousands of women, who over the past two decades have chosen bioidentical hormones based on their physicians' assessments. They are living proof that bioidentical hormones are safer and more effective and reliable than synthetic hormone drugs.

A physician and user of bio-identical hormones writes:

Wyeth, the filer of this complaint, is trying to prevent women from being able to choose less expensive compounded options for hormone replacement. There is medical evidence that in modifying the structure of their drugs (such as Premarin and Prempro) so that they could be patented, they may have introduced factors that cause the health risks identified in the Women's Health Initiative. This complaint appears to be filed for commercial purposes because of the market share that has shifted from Wyeth's products to bio-identical products from compounding pharmacies. If the complaint were upheld, patients and their doctors would not have a choice in hormone treatments. Wythe's commercial strategy of trying to eliminate the 'competition' from compounding pharmacies is against the public interest and in the interest of its own corporate profits. Women and their doctors should be able to choose between patented formulations such as those offered by Wyeth, bioidentical formulas available from compounding pharmacies, and no hormone treatment. I have been taking bio-identical hormones for several years and have had excellent results in improving my symptoms. I have been unable to take other synthetic hormones in the past, and am very concerned that my best treatment option will be taken away.

If you get a 64-slice CT coronary angiogram

With new 64-slice CT scanners popping up everywhere nowadays, be sure to get your heart scan with it.

The new scanners do indeed provide wonderful images of the coronary arteries. But, say you have a 20% blockage in one artery by a coronary angiogram generated on one of these devices. What will you do in 1, 2, or 3 years when you want to know if you have progressed? Should you have the CT angiogram repeated?

Well, if you did you'll be exposed to a large dose of radiation--appropriate for a diagnostic test, but not for a screening test. The radiation exposure is not that different from undergoing a full conventional cardiac catheterization, or up to 100 chest x-rays.

"20% blockage" is also, contrary to popular opinion, not a quantitative measure. It is just an estimate of the diameter reduction at one spot. That number says nothing about the lengthwise extent of plaque. It also says nothing about the potential for "remodeling", the phenomenon of artery enlargement that occurs as plaque grows. In other words, if you had another CT coronary angiogram a year later and was told that your blockag was still 20%, in reality you could have had substantial plaque growth but it would not be reflected in that value.

People will come to me after having a CT angiogram for an opinion. Unfortunately, I send them back to their scan center to get a simple coronary calcium score. That measure is easy, quantitative, precise, and can be repeated yearly if necessary to track progression. (Track Your Plaque--I hope most of you get this by now.) Some physicians poke fun at the heart scan, or calcium, score--it's old, boring, only a measure of hard plaque. None of that's true. The coronary calcium score is a measure of total plaque (hard and soft). And when you are empowered to learn how to control and reduce your score, then it's the most exciting number in your entire health program!

Don't fall for the hype. If you go to a scan center and they insist on a 64-slice CT scanner, or if your doctor orders one, you should insist on getting a calcium score out of the test. Just ask. If they refuse, go somewhere else. Centers that refuse to generate a score have one thing on their mind: identifying people with severe blockages sufficient to obtain the downstream financial bonanza--angioplasty, stents, and bypass surgery.

If you have hypertension, think Lp(a)

Clair has coronary disease.

Clair first came to attention at age 57 when she suffered a large heart attack involving the front of her heart (the "anterior wall") two years ago. Her cardiologist implanted a drug-coated stent. Her doctors advised her to "cut the fat" in her diet, exercise, and take Lipitor.

One year later, she required a stent to another artery (circumflex). At this point, Clair was thoroughly demoralized and terrified for her future. Her first heart attack left her heart muscle with only 50% of normal strength.

She came to my office for another opinion. Of course, one of the first things we did was to identify all causes of her heart disease. No surprise, Clair had 7 new causes not previously identified, including low HDL (37 mg/dl), a severe small LDL particle pattern (75% of all particles were small), and Lp(a).

Her blood pressure was also 190/88, despite her relatively slender build and 3 medications that reduced blood pressure. That's a Lp(a) effect: Exagerrated coronary risk along with unexpected hypertension that often seems inappropriate.

In fact, I saw several patients just this week with lipoprotein(a), Lp(a), and exagerrated high blood pressure (hypertension). It's not that uncommon.

Though it has not been described in the medical literature, our experience is that hypertension is a prominent part of the entire Lp(a) "syndrome".

Lp(a) is responsible for much-increased potential for coronary disease (coronary plaque). It increases in importance as estrogen recedes in a woman (pre-menopause and menopause) and testosterone in a man, since both hormones powerful suppress Lp(a) expression (though why and how nobody knows).

I believe that Lp(a) is also responsible for hypertension that most commonly develops in a persons mid-50s and onwards, often with a vengeance. 3 or 4 anti-hypertensive medications and still not controlled.



Role of l-arginine

L-arginine may be more helpful in this situation than others. L-arginine, recall, is the supply for your body's nitric oxide, a powerful dilator of the body's arteries and thereby reduces blood pressure. We use 6000 mg twice a day, a large dose that requires use of powder preparations rather than capsules.

More reading about l-arginine and nitric oxide is available through Nobel laureate, Dr. Louis Ignarro's book, NO More Heart Disease : How Nitric Oxide Can Prevent--Even Reverse--Heart Disease and Stroke, available at Amazon.com ( http://www.amazon.com/gp/product/0312335814/104-1247258-6443909?v=glance&n=283155).




Will l-arginine truly reverse heart disease on its own? No, I don't believe so. Contrary to Dr. Ignarro's extravagant claims, I find l-arginine a facilitator of plaque regression, i.e, it helps other strategies achieve regression, but it does not achieve regression or reversal by itself. (Note that Dr. Ignarro is a lab researcher who studies rats and has never treated a human being.)

But l-arginine may have special application in the person with lp(a), particularly if hypertension is part of the syndrome.


Note: As always, please note that I talk frankly about l-arginine and other supplements and medications but have no hidden agenda: I am not selling anything, nor am I affiliated with any source/website/store etc. that sells these products. If I advocate something, I do so because I truly believe it, not because I'm trying to sell something. I make this point because so much nonsense is propagated in the media because of profit-motive. That's not true here.

Dr. Ornish: Get with the program!


In the era up until the 1980s, most Americans indulged in excessive quantities of saturated fats: fried chickem, spare ribs, French fries, gravy, bacon, Crisco, butter, etc.

Along came people like Nathan Pritikin and Dr. Dean Ornish, both of whom were vocal advocates of a low-fat nutritional approach. In their programs, fat composed no more than 10% of calories. This represented a dramatic improvement--at the time.


In 2006, a low-fat diet is a perversion of health. It means over-reliance on breads, breakfast cereals, pasta, crackers, cookies, pretzels, etc., the foods that pack supermarket shelves and that now constitute 70-80% of most Americans' diet.

Dr. Ornish still carries great name recognition. As a result, his outdated concepts still gain media attention. The June, 2006 issue of Reader's Digest, in their RDHealth column, carried an interview with Dr. Ornish in which he reiterates his fat-phobia.

However, on this occasion he takes a different tack. This time he rails against the "dangers" of fish oil and omega-3 fatty acids. "I've recently learned that omega-3s are a double-edged sword...In some cases, omega-3s could be fatal."

He goes on to say that, while he believes that fish oil may prevent heart attacks, it has fatal effect if you already have heart disease.

Does this make sense to you?

He's basing his views on a single, obscure study published in 2003 conducted in rural England that showed an increase in death and heart attack on fish oil. Most authorities have not taken these findings seriously, since they are wildly contrary to all other observations and because the study had some design flaws.

Despite the fact that this isolated study runs counter to all other, better-conducted studies seems not to matter to Dr. Ornish.

Clinging to the low-fat concept is like hoping 8-track tapes will make a comeback. It's not going to happen. We enjoyed the benefits while they lasted, appropriate for the era. But now, they're woefully outdated.

The overwhelming evidence is that fish oil provides tremendous benefits with little or no downside. In the Track Your Plaque program, fish oil remains a crucial supplement to gain control over your coronary plaque and stop or reduce your heart scan score. Ignore the doomsday preachings of Dr. Ornish.

(Watch for an article I wrote updating the benefits of fish oil for Life Extension magazine.)

The cholesterol fallacy

Evan spotted the kiosk set up in the middle of the local mall. "Free cholesterol screenings. Know your heart health!" the sign declared.

It was a free cholesterol screening being offered by a local hospital.

The friendly nurse behind the kiosk had Evan fill out a form, then pricked his finger. Five minutes later, she reported to him with a smile, "Sir, your cholesterol is 177--your heart's fine! We get concerned when cholesterol is over 200. So you're in a safe range."

What the nurse failed to recognize is that Evan's HDL was 30 mg, a low value that actually places him at high risk for heart disease. Low HDL also signifies high likelihood of the small LDL particle pattern, a marked predisposition towards pre-diabetes and diabetes, a probable over-reliance on processed carbohydrates in his diet, a dramatically increased probability of hidden inflammation (e.g., elevated C-reactive protein), increased tendency for high blood pressure. . .

In other words, Evan's "favorable" total cholesterol is, in truth, nonsense. It's misleading, falsely reassuring, and provided none of the insight that a real effort might have yielded. Like hippies, tie-dye, other relics of the 1960s, total cholesterol needs to be put to rest. It has served many people poorly and been responsible for countless deaths.

When you see a kiosk or other service like this, even if it's free, run the other way.

"Heart disease a growth business"





So announced a Boston newspaper recently, featuring a story about new heart program at a local hospital.

They were announcing how a hospital had entered the cardiovasculare procedure game and how it would boost their bottom line. The article discussed how the hospital administration was anticipating "a surge in patients from the baby boom generation."

To justify this new program, the article quoted an administrator from another hospital: "Cardiovascular issues is [sic] the number one cause people sought treatment at our hospital."

The hospital featured in the story had spent $13.5 million dollars to develop their program.

Do you think they'll make it back?

You bet they will--many times over. Hospitals are businesses, complete with a bottom line, an expectation of profit and an eye towards growth.

The hospitals in the city where I live (Milwaukee, Wisconsin) are, as in Boston and elsewhere, very aggressive--expanding into new territories, hiring new "salesmen" (physicians), all to capture more marketshare and produce more "product" (your coronary angioplasty, stent, bypass surgery, defibrillator, etc.).

The equation for hospital profits is tried and true. Ignore your heart disese risk and you can help your local hospital grow its business. Neglect to get your heart scan and you can help your hospital pay down its debt. Get a heart scan, then do nothing about it, and you may even justify a pay raise for the hospital administrators for record revenue growth and profit.

Hospitals are a growth business because of the failure of most people and their doctors to 1) identify hidden coronary disease (CT heart scan to obtain your heart scan score), then 2) seize control over it (the Track Your Plaque program or, at least, your doctor's guidance along with your efforts at prevention).

Unless you do so, you are highly likely to help your hospital boost its annual goal for procedures.

The myth of small LDL

Annie's doctor was puzzled.

Despite an HDL cholesterol of 76 mg (spectacular!) and LDL of 82 mg, her CT heart scan showed a score of 135. At age 51, this placed her in the 90th percentile.

Not as bad, perhaps, as her Dad might have had, since he died at age 54 of a heart attack.

So we submitted blood for lipoprotein testing. Surprise! over 90% of all her LDL particles were small. (By NMR, they're called "small". By gel electropheresis, or the Berkeley Lab test, or VAP (Atherotech) technique, they're called "HDL3".)

What gives? Traditional teaching in the lipid world is that if HDL equals or exceeds 40 mg/dl, then small LDL will simply not be present.

Well, as you can see from Annie's experience, this is plain wrong. Yes, there is a graded, population-based effect--the lower your HDL, the greater the likelihood of small LDL. But small LDL is remarkably persistent and prevalent--regardless of your HDL.

We've seen small LDL even with HDLs in the 90's! I call small LDL the "cockroach" of lipids. If you think you have it, you probably do. Getting rid of small LDL requires a specific bug killer. (Track Your Plaque Members: Read Dr. Tara Dall's interview on small LDL.)

Don't let anybody blow off your request for lipoprotein testing just because your HDL is high. That's just not acceptable. Loads can be wrong even with a favorable HDL.

My stress test was normal. I don't need a heart scan!

Katy had undergone a stress test while being seen in an emergency room, where she'd gone one weekend because of a dull pain on the right side of her chest. After her stress test proved normal, she was diagnosed (I believe correctly) with esophageal reflux, or regurgitation of stomach acid up the esophagus. She was prescrbed an acid-suppressing medication with complete relief.

But Katy also had coronary plaque. Three years ago, her CT heart scan score was 157. She'd made efforts to correct the multiple causes, though she still struggled with keeping weight down to gain full control over her small LDL particle pattern.

I felt it was time for a reassessment: another heart scan. After three years, without any preventive efforts, Katy's score would be expected to have reached 345! (That's 30% per year plaque growth.) It's a good idea to get feedback on just how much slowing you've accomplished.

But Katy declared, "But I didn't think another heart scan was necessary. My stress test was normal!"

What Katy was struggling to understand was that even at the time of her first scan, a stress test would have been normal. Plaque can be present with a normal stress test.

Plaque can even show explosive growth all while stress tests remain normal. Just ask former President, Bill Clinton, how much he should have relied on stress tests. (Mr. Clinton underwent annual stress nuclear tests. All were normal and he had no symptoms--all the way up 'til the time he needed urgent bypass surgery!)

Of course, at some point even a crude stress test will reveal abnormal results. But that's years into your disease and a lot closer to needing procedures and experiencing heart attack.

So, yes, Katy would benefit from another heart scan despite her normal stress test.

The message: Don't rely on stress tests to gauge whether or not plaque has grown, stabilized, or reversed. Stress tests can be used to gauge the safety of exercise, blood pressure response, and the potential for abnormal heart rhythms. Stress tests can be used as a method to determine whether blood flow in your coronary arteries is normal through an area with plaque.

But a stress test cannot be used to gauge whether plaque has grown. It's as simple as that. Gauging plaque growth requires a heart scan.

Patient-napping: Yet another reason to stay clear of hospitals!

When I started practicing medicine around 20 years ago, it was common practice to alert a physician when their patient was seen in an emergency room.

If John Smith, for example, went to the emergency room with chest pain, the physician who had an established relationship with the patient--knew their history, had managed their health and illnesses, etc.--was notified, even if the hospital ER had no relationship with the physician. It was not uncommon for the patient to then be transferred to the hospital where their own doctor practiced.

Though cumbersome at times, it preserved the relationship of the patient with their doctor.

Over the past few years, this practice has crumbled. Nowadays, hospitals and their employed physicians (and other unscrupulous physicians acting in the name of profit) "fail" to notify the physician with an established relationship.

Guess what happens? The patient all too often ends up being put through the gamut of testing and procedures.

Why? For hospital profit, of course. If failure to notify a doctor who's had a 10-year long relationship with the patient is "overlooked" or, even more commonly, it's "unsafe" to transfer the patient because the patient is too "unstable" to be transferred, then this patient becomes ripe for picking--heart catheterization, stents, bypass surgery, etc. Ten's, if not hundreds, of thousands of dollars can be reaped by this deception. I call it "patient-napping".

I see this at least several times every month. As hospitals are becoming increasingly competitive, and as they put pressure on their physicians to churn patients for revenues, you're going to see more and more of this.

As always, what is your protection from this expanding influence of hospitals and the doctors too meek to stand up to them? Education and information. Arm yourself with an understanding of what is accomplished in hospitals, when you truly need them, and when you don't.

Take it one step further. At least from a heart disease standpoint--the #1 profit-maker for hospitals--aim to 1)identify your coronary plaque, then 2) seize control over your coronary plaque and reduce your risk for heart attack and heart procedures as much as humanly possible. That's the goal of the Track Your Plaque program.

Don't believe the negative press on fish oil



A British Medical Journal study released in March, 2006 has prompted a media flurry of reports on the worthlessness of fish oil. (Hooper L, Thompson RL, Harrison RA et al. Risks and benefits of omega 3 fats for mortality, cardiovascular disease, and cancer: a systematic review. BMJ March,2006)

Don't believe it for a second.

First of all, the study was a re-analysis of the existing published scientific literature. It was not a new study. It included a wild conglomeration of different clinical observations, as the studies examining fish oil over the years have been extraordinarily heterogeneous--in populations examined, omega-3 supplement (e.g., fish vs. capsule), period of observation, endpoints measured.

The results were skewed by inclusion of a moderate-sized British study by Burr et al in men with angina. In this study, no benefit was demonstrated and, in fact, a negative effect--more heart attack and death--was observed with fish oil. This was not news, since the study was published in 2003. It's results have been a mystery to everyone, since its unexpected negative result for fish oil was so starkly different from virtually every other study that preceded it (suggesting a study flaw or statistical fluke).

Nonetheless, the Burr study served to throw off the overall analysis. It diluted the dramatic and persuasive outcome of the GISSI-Prevenzione Study of 11,000 people in which a 28% reduction in heart attack and 45% reduction in cardiovascular death was observed. Note that the substantial numbers of the GISSI make the study's outcome nearly unassailable.

Another important fact: fish oil is among the most powerful tools available to correct elevated triglycerides. Drops of 50% are common. Recall that triglycerides are a necessary ingredient to create the nasty LDL, as well as VLDL, Intermediate-density lipoprotein, and an undesirable shift from large to ineffective small HDL. Reducing triglycerides is therefore crucial for your plaque control program.

This re-analysis serves to prove nothing. Such analyses can only pose questions for further study in a real study like GISSI: a randomized (random participant assignment), controlled (treatment vs. placebo or other treatment) study.

The weight of evidence remains heavily in favor of fish oil, not only as helpful, but fabulously beneficial, particularly for anyone aiming to reduce coronary plaque.

How important is high blood pressure?


Control of blood pressure is crucial for coronary plaque control and stopping your heart scan score from increasing.

Dr. Mehmet Oz (of Oprah fame and a cardiac transplant surgeon at Columbia University) made graphic point of this on the ABC TV news show, 20/20, last evening on an episode called "Our Bodies: Myths, Lies, and Straight Talk". (See a summary on the ABC News 20/20 website at http://abcnews.go.com/2020/story?id=2109291&page=1)

Although I believe he somewhat overstated the case for hypertension (proclaiming "If you're going to remember one number, if you're going to focus and fixate on one number in your entire health profile, it better be your blood pressure"), he made the point that a blood pressure of 115/75 is what you should have for optimal health.

I couldn't agree more. Unfortunately, the old advice that desirable blood is 140/90 or less is absolutely wrong. At this level, we see flagrant increases in heart scan scores. We also progressive enlargement of the thoracic aorta, the large vessel that leaves the heart and branches to provide the major arteries of the body. Growth of the aorta to an aneurysm is also common at these formerly acceptable blood pressure. (The diameter of your aorta in the chest is an easily obtainable measure on your CT heart scan.)

The blood pressure you need for halting and reversing plaque growth on your heart scan is indeed 115/75 or less. (Not so low, however, that you're lightheaded.) This is the blood pressure that you were meant to have evolutionarily. It's also the blood pressure that helps tremendously in keeping your aorta from enlarging.

Watch for an upcoming exhaustive report on blood pressure and its plaque-raising effects and how to reduce it using nutritional strategies on the www.cureality.com membership website.

Is your doctor in cahoots with the hospital?

I got a call from a doctor about a patient we've seen in past.

"I've got Tricia in the office. She's been having some kind of chest and abdominal pain. I think it's esophageal reflux, but just to be safe I'm sending her to the hospital."

I advised this physician that, given Tricia's low heart scan score, she was unlikely to be having a coronary "event" like heart attack or unstable symptoms. It wasn't impossible, but just highly unlikely.

As the patient was without symptoms at the moment and had driven herself to his office, I offered to perform a stress test immediately. (Though stress tests are of limited usefulness in people without symptoms, they can be useful provocative maneuvers in people with symptoms of uncertain significance.)

The doctor declined. Tricia was, after all, in his office and he was responsible for any decisions despite any objections I voiced. Well, Tricia was directed by her doctor to go to a local hospital, though one with an especially notorious reputation for putting virtually anyone they can get their hands on through as many procedures as possible.

As you might guess, this doctor was closely associated with this hospital. He and his colleagues obtain incentives (or are penalized) if they do not generate revenue-producing procedures for the hospital.

So, guess what? Tricia ended up with several procedures, all of which yielded nothing--except $30,000 in revenues from Tricia's insurance company.

I harp on this deplorable state of affairs because it is utterly, painfully, and shamefully TRUE. Just look at the hospital and you'd better brace yourself for a series of tests that could cost you the equivalent of a nice 3 bedroom home. If they were truly necessary after the failure of preventive and other simple efforts, fine. But, all too often, they are driven by profit motives.

Could I have stopped this somehow from occurring? After all, Tricia was reasonably aware of the way we do things around here. I fear that even this failed to serve Tricia well. But I remain hopeful that, as we build broader awareness of these issues, that more and more people and physicians will stand up and refuse to tolerate the status quo.

Where is the Track Your Plaque program going?

I spend a lot of time worrying about how people can be helped to navigate through this program.

Take, for instance, the man in rural Texas who, while traveling in Dallas, got a heart scan on a whim. His score was 990. When he took the report back to his doctor, he got a smirk--and that's all. When he came to the Track Your Plaque program, he lacked a physician advocate to help him.

Or the woman from Florida who sought opinions from two reputable cardiologists for her heart scan score of 377. Both advised her that she needed a heart catheterization--despite her lack of symptoms, her 5-day-a-week exercise program, and normal stress test. She also lacks a physician advocate who acts on her behalf, helping her achieve success, rather than just churning her for money from hospital procedures.

For people like this and for others, I see the Track Your Plaque program evolving in several directions:

1) An online clinic--You enter and we take your "hand" and lead you step by step through the process, not only at the beginning, but over the months and years. This would help clear up some of the confusion and zigzags that some people experience trying to navigate through the program.

2) Develop physician and non-physician partners--The woman in Florida, for instance, could be referred to a doctor nearby who understands the program and is able to assist her. At present, this is virtually impossible because of the bias towards heart procedures, drugs as the sole treatment for heart disease risk, and the superficial physician-patient relationship. The majority of practicing physicians just don't understand the program despite the fact that it is based on sound clinical and experimental data. But it will in time.

Looking back, we've come a long way. I remember first having patients undergo heart scans 10 years ago. My colleagues laughed or called it "silly". The general public didn't know what they meant.

Now we're talking about how to broadcast the most powerful heart disease prevention program available in the world to a larger audience, but making it easier and more accessible. Mass media like Oprah's two hour-long spots helped, but we need to make the next leap. Not just identifying hidden heart disease to feed the hungry cardiovascular hospital procedure monster, but to educate/inform/empower the public on what to do with the scan once they've had it.

Who cares about triglycerides?

Walter's triglycerides were 231 mg. His LDL cholesterol was "favorable" at 111 mg, HDL likewise at 49 mg.

"Everything looks good," his doctor declared.

"Do you think the triglycerides are okay, too?" Walter asked.

"Well, the guidelines do say that triglycerides should be less than 150, but I believe you're close enough. Anyway, triglycerides don't really cause heart disease."


When I met Walter, I made several comments. First of all, in light of his heart scan score of 713, none of his numbers--HDL, LDL, or triglycerides-- were acceptable. But the triglycerides were glaringly and terribly too high.

Why? What exactly are triglycerides?

Triglycerides are a basic fat particle that, though they do not cause heart disease directly, trigger the formation of an array of abnormal lipoprotein particles in the blood that are among the most potent causes of heart disease known.

These abnormal lipoprotein particles include small LDL, VLDL, and IDL (intermediate-density lipoprotein--a really bad pattern). Excess triglycerides also cause HDL to drop. They also cause a distortion of HDL structure, causing the particles to become abnormally small. Small HDL is also useless HDL, unable to provide the protection that HDL is designed to do.

So Walter's elevated triglycerides are, in reality, a substantial red flag for an entire panel of abnormal particles that contribute to the growth of his coronary plaque.

So, if you get this kind of commentary on your triglycerides, ask for another opinion. (Track Your Plaque Members: Also see Triglycerides: Mother of meddlesome particles at http://www.cureality.com/library/fl_dp002triglycerides.asp.)

Total cholesterol and heart scans

Andy was fearful of heart disease in his life. At age 52, he'd already had four CT heart scans--one each year on or near his birthday.

Yet, when I looked at Andy's scans, his scores had been increasing 20-24% per year. Each and every score was greater by 20% or more over the previous.

So I asked Andy what steps he had taken to stop this relentless progression. "Well, I've always been real health conscious. But ever since my first scan, I really started sticking to a healthy diet, exercising nearly every day, and I take a bunch of supplements."

"What did your doctor advise?" I asked.

"Well, Dr. ---- said that nothing needed to be done, since my total cholesterol was always below 200."



Men's Health magazine's fabulous story about the folly of using total cholesterol to gauge heart disease risk.




Aaaauuuggghhh!! Wrong!

This man was, in fact, at rapidly escalating risk for heart attack. This rate of growth simply can't continue forever without igniting this bomb.

A total cholesterol below 200 is meaningless, as Andy's increasing coronary plaque proved. For instance, you can have a total cholesterol of 165 mg but with an HDL cholesterol of 27 mg. This would constitute very high risk for heart disease despite the low total cholesterol. The low HDL pattern is among the most common reasons for a misleading total cholesterol. Small LDL, high triglycerides, and lipoprotein (a) are other frequent reasons.

Andy, run the other way! Do not heed this doctor's advice! You need a solid answer to the question: Why exactly do I have coronary plaque in the first place?

Then, agree on a treatment program that corrects your specific causes.

Cardiologists out of touch

This weekend, I'm fulfilling some responsiblities I have every so often to some of the local hospitals. It gives me a chance to interact with many of my colleagues who are likewise "on call" for the weekend.

I tried to strike up several conversations with colleagues about how they were managing heart disease prevention. I received blank stares, puzzled looks, indifference. One colleague declared that 80 mg of Lipitor is all you need to know.

These same colleagues are the ones scrambling for the heart attack patients in the emergency room, climbing over one another for consultation in the hospital for patients with chest pain and heart failure. They're consumed with expanding the range of procedures they can perform.

Carotid stenting is hot. So is stenting of the leg arteries. Defibrillators have been a financial bonanza. Opportunities abound on how to add these procedures to a cardiologist's abilities.

But heart disease prevention? How about heart disease reversal?

Frankly, I'm embarassed by my colleagues' lack of interest. Imagine we had a cure for breast cancer--not a palliative therapy that just slows the disease down or prolongs life, but actually cures it once and for all. I would hope that all physicians and oncologists would learn how to accomplish this. What if instead they focused on learning new ways to remove breasts, administer new toxic chemotherapies, etc. but ignored the whole idea of cure?

This is what is happening with coronary plaque reversal. The answer is right in front of them, but the vast majority (99%) of cardiologists choose to ignore it. After all, prevention and reversal simply don't pay the bills.

That means that, in 2006, you simply cannot rely on your cardiologist to counsel you on how to achieve regression or reversal of coronary plaque. How about your internist, family physician, or primary care doctor? Well, they're busy doing pneumovax injections, Pap smears, managing knee and hip arthritis, low back pain, diarrhea, headaches, sinus infections and . . yes, dabbling in heart disease prevention.

And, for the most part, doing a miserable job of it. What you generally get echoes the drug manufacturers pitch: Take a statin drug, cut the fat in your diet.

Until the majority of doctors catch on, you're going to have to rely on sources like the Track Your Plaque program for better information.

What if your lipoproteins are perfect?



Sandy is a 56-year old woman--fit, slender, physically active, with no bad habits. A retired teacher, she has time to devote to her health. She bikes several days per week, mountain bikes, walks, and takes fitness classes. In short, she's the picture of perfect health.

Her heart scan score was not terribly impressive: 41. However, at her age, this modest score placed her in the 77th percentile. This suggested a heart attack risk of around 2-3% per year.

So we measured Sandy's lipoproteins. They were shockingly normal. In fact, Sandy is among the very rare person with absolutely no small LDL particles. All other patterns were just as favorable, including an HDL in the 80s.

This may seem like good news, but I find it disturbing. People are often initially upset by seeing multiple abnormal lipoprotein patterns. But lipoprotein abnormalities are the tools that we use to gain control over coronary plaque.

So what do we do when there are no abnormalities?

There are several issues to consider:

1) Your heart scan score reflects the sum total of your life up until that point. What if you were 20 lbs heavier 10 years earlier and your lipoproteins were abnormal during that period? Or you smoked until age 45 and quit? As helpful as they are, lipoproteins and related patterns are only a snapshot in time, unlike the heart scan score.

2) You have a vitamin D deficiency. This is unusual as a sole cause of coronary plaque. Much more commonly, it is a co-conspirator.

3) The heart scan is wrong--highly unlikely. Heart scans are actually quite easy, straightforward tests. (The only time this tends to happen is when scoring that appears in the circumflex coronary artery is actually in the nearby mitral valve. This really occurs only when there's very minimal calcium in the valve.)

4) There's a yet unidentified source of risk. Probably very rare but conceivable. For instance, there's an emerging sense that phopholipid patterns may prove to be coronary risks. One clinically available measure that we've not found very useful is phospholipase A2, known by the proprietary name "PLAC" test. (See http://www.plactest.com for more information from the manufacturer/distributor of the test.) But there's probably lots of others that may prove useful in future.

How often does it happen that someone fails to show any identifiable source for their coronary plaque? I can count the number of instances on two fingers--very unusual. (Thank goodness!)

Sandy's case is therefore quite unique. How should we approach her coronary plaque? In this unusual circumstance, lacking a cause, we tend to introduce therapies that may regress plaque independent of any measurable lipoprotein parameters. But that's a whole new conversation.

Fly to India for a bypass operation?


In the June 19, 2006 issue of People Magazine, there's an article called "The Doctor is in . . .INDIA". The report talks about how, with health care costs in the U.S. spiralling out of control, more and more Americans are leaving the country to have their procedure performed.

They tell the story of Mr. Carlo Gislimberti of New Mexico and cite these numbers:

Heart Surgery
Cost in U.S.: $200,000

Cost in India: $10,000


Mr. Gislimberti opted to have his coronary bypass operation in India for cost reasons.

But the People magazine report left out one other option: The Track Your Plaque program: $39.00

Do your part to save ballooning health care costs: Engage in a truly powerful program of heart disease prevention like the Track Your Plaque program. The cost difference is laughably huge. And you won't require a 12-inch chest incision.

Follow conventional guidelines and guess what? You're going to have a heart attack. Follow the American Heart Association diet and you'll have heart disease.

Cut to the chase. The only program that is able to detect, track, and control coronary plaque better than any other process I know of is this program.

Note: I am not proposing that a heart disease prevention program like Track Your Plaque can replace a procedure like coronary bypass when a dangerous situation has developed. The Track Your Plaque program is designed to be implemented in the years before heart surgery is required. That's when you have the greatest control over your fate.

Surprise: Heart scan score reversal

Gene is a jovial, fun-loving railroad worker who didn't take anything too seriously--including his heart scan score of 767.

This score placed Gene solidly in the 99th percentile (in the worst 1%). It came as no surprise to Gene. After all, his father died at age 36 of a heart attack and Gene's brother died at 60 of a heart attack. So Gene took life as it came and long ago decided not to fret about his fate.

But Gene's wife prodded him and prodded him to get the heart scan. That's when I met him.

Of course, Gene had been prescribed Lipitor by his doctor for a somewhat high LDL cholesterol. Our assessment uncovered several additional patterns including lipoprotein (a), small LDL, a pre-diabetic tendency, and a severe deficiency of vitamin D.

At 224 lb and 5 ft 6 inches in height, I felt that Gene was at least 40 lbs overweight.

One year later and with reasonable correction of all his patterns except weight loss and Gene's heart scan score was 590--a reduction of 23%!

Gene was thrilled, as was I. But, frankly, I was also surprised. Dramatic regression of coronary plaque tends to not occur so readily as long as pre-diabetic patterns persist and weight is not controlled.

The lesson: Often the only way to tell if you've achieved control or regression of coronary plaque is to have another heart scan. The tremendous variation in human responses never ceases to amaze me.

Call me when you're having chest pain


I met a patient, Anna, yesterday. She was quite frustrated and frightened.

At age 50, Anna suffered a heart attack and received a stent to her left anterior descending coronary artery. What she found upsetting is that, because several members of her family had suffered heart attacks in their 40s (Dad--heart attack at age 45, paternal uncle--heart attack age 40, and even another uncle with heart attack in his late 20s), she had repeatedly asked her doctor whether she was okay.

She received the usual array of false assurances: "You're feeling fine, right? Then don't worry about it." "Look. Your cholesterol is in the normal range. Even your cholesterol/HDL ratio is fine." "Women don't get heart disease until later in life."

All proved absolutely false. As we talked, Anna exclaimed, "I think what I've been told all along is that we'll take you seriously when you finally have a heart attack!"

She's exactly right. The vast majority of times, heart disease is discovered by accident, usually because of an "event" like heart attack. This is like changing the oil in your car when it finally breaks down--it's too late.

CT heart scan, followed by lipoprotein testing and associated values, then correction of your specific causes. It's that simple.

The myth of mild coronary disease

I hear this comment from patients all the time:

"They told me that I had only mild blockages and so I had nothing to worry about."

That's one big lie.

I guess I shouldn't call it a lie. Is it a lie when it comes from ignorance, arrogance, laziness, or greed?

"Mild coronary disease" is usually a label applied to coronary atherosclerotic plaque that is insufficient to block flow. Thus, having a few 20%, 30%, or 40% blockages would be labeled "mild." No stents are (usually) implanted, no bypass surgery performed, and symptoms should not be attributable to the blockages. Thus, "mild."

The problem is that "mild" blockages are no less likely to rupture, the eruptive process that resembles a little volcano spewing lava. Except it's not lava, but the internal contents of atherosclerotic plaque. When these internal contents of plaque gain contact with blood, the coagulation process is set in motion and the artery both clots and constricts. Chest pains and heart attack result.

So, the essential point is not necessarily the amount of blood flow through the artery, but the presence of coronary atherosclerotic plaque. Just having plaque--any amount of plaque--sets the stage to permit plaque rupture.

One thing is clear: The more plaque you have, the greater the risk for rupture. But the quantity of plaque cannot be measured by the "percent blockage." It is measured by the lengthwise extent of plaque, as well as the depth of plaque within the wall. Neither of these risk features for plaque rupture can be gauged by percent blockage.


Coronary atherosclerosis is a diffuse process that involves much of the length of the artery. It is therefore folly to believe that a 15 mm long stent has addressed the disease. This is no more a solution than to replace the faucet in your kitchen in a house with rotting pipes from the basement up.

The message: ANY amount of coronary plaque is reason to engage in a program of prevention--prevention of plaque rupture, prevention of further plaque growth, perhaps even regression (reversal). It is NOT a reason to be complacent and buy into the myth of "mild" coronary disease, the misguided notion that arises from ill-conceived procedural heart disease solutions.

Red flags for lipoprotein(a)



Lipoprotein(a), Lp(a), is an important cause for heart disease, heart attack, and coronary atherosclerotic plaque.

How do you know you have it?

Of course, it could be as simple as checking a blood level. But there are also a number of red flags for the presence of Lp(a), tell-tale signs that suggest it is present and contributing to the growth of coronary plaque.

I've seen so much of this pattern over the years that it's gotten so that I can pretty much pick out most of the people with Lp(a) just by either looking at them or by hearing their story. I do this simply by knowing what hints to look for.

Some of the red flags for Lp(a) include:

--High blood pressure in a slender person. Overweight is the overwhelmingly common reason for high blood pressure. However, inappropriate high blood pressure in a slender person can serve to tip you off that Lp(a) is present.

--HIgh LDL cholesterol poorly responsive to statin drugs. For instance, someone's LDL cholesterol of 190 mg/dl will be treated with Lipitor 40 mg, but drops to only 165 mg/dl, a very poor response. This can sometimes point towards Lp(a).

--Family clustering of heart disease in people before age 60. For instance, father with heart attack age 53, uncle with heart attack at age 55, aunt with heart attack age 59, etc. This clustering of risk, more often than not, signals Lp(a).

--Coronary disease or high heart scan score in the presence of relatively bland appearing lipids. For instance, LDL cholesterol 130 mg/dl, HDL 55 mg/dl, triglycerides 70 mg/dl on no medications or other efforts--figures ordinarily not associated with high likelihood of heart disease--yet heart disease is indeed present. This can mean that Lp(a) is the concealed culprit behind coronary atherosclerosis.

These red flags are not perfect. If you lack any of them, it doesn't necessarily rule out the possbility of having Lp(a). They simply serve as signs to suggest that Lp(a) may be lurking.

Once Lp(a) is identified, then the battle begins to gain control over this somewhat troublesome genetic pattern. Resourcesfulness and some ingenuity may be required. However, knowing that you have it shows you where to concentrate your efforts.

Vytorin study explodes--But what's the real story?

The makers of Vytorin, Merck/Schering-Plough Pharmaceuticals, issued a press release about the the Enhance Study yesterday. The news has triggered a media frenzy.

The NY Times reporting of the story:

Drug Has No Benefit in Trial, Makers Say

The 700 participants in the trial all had a condition called "heterozygous hypercholesterolemia," a genetic disorder that permits very high LDL cholesterols. The average LDL at the start was 318 mg/dl.

The Times reported that, while Vytorin cut "LDL levels by 58 percent, compared to a 41 percent reduction with simvastatin alone," but "the average thickness of the carotid artery plaque increased by 0.0111 of a millimeter in patients taking Vytorin, compared to an increase of 0.0058 of a millimeter in those taking only simvastatin." There was no difference in heart attacks or other "events" between the two groups.

(Vytorin is the combination of simvastatin and Zetia.)

In other words, the participants taking Vytorin had 53 ten-thousands of a millimeter more plaque growth than the group taking just simvastatin.

I am always uncomfortable when put in the position of defending a drug or drug company. However, it is patently absurd that this study has generated such attention. I suspect the public and media are waiting for another Vioxx-like debacle, with memories of concealed or suppressed data that suggested heightened heart attack risk that was dismisssed by the drug manufacturer. (That's not to say that the company hasn't been trying to delay or modify the outcome of the study, which they apparently have, much to the objections of the FDA.)

However, at this point, there is no reason to believe that this question possesses any parallels to the Vioxx fiasco.

If we accept the data as reported, however, we might say it calls the entire "Lipid Hypothesis" into question: If LDL cholesterol is significantly reduced but is not correlated with reduction in plaque, is LDL the means by which atherosclerotic plaque progresses? This trial does not answer that question, but does serve to raise some doubt.

Another issue: Heterozygous hypercholesterolemia, and thereby LDL cholesterol, may not be the overwhelming driver of plaque growth in this population. It is probably the number of small LDL particles, a factor which is not revealed by LDL cholesterol. For this reason, heterozygous hypercholesterolemia by itself is insufficient to cause heart disease. Some other factor(s) needs to be present. I would propose that it is the size of the LDL particle: When small, heart disease develops; when large, heart disease is less likely to develop. This issue was not addressed by this study. Readers of The Heart Scan Blog know that conventional LDL cholesterol, the number used in this study, is a virtually worthless number for truly gauging plaque behavior because of its flagrant inaccuracy.

So, there are substantial uncertainties, contrary to the absolute certainty expressed by people like Dr. Steve Nissen (who, by the way, has no expertise in lipoprotein disorders). It is premature to reach any firm conclusions from this study. The only conclusions that I personally come to are 1) Is this yet another reason to question the entire Lipid Hypothesis as it stands? and 2) What would the results have been had LDL particle number and LDL particle size been examined, not just LDL?

I would not automatically conclude that Zetia causes carotid plaque. This is absurd. And I am definitely not one to come to the rescue of a drug or drug manufacturer. I am simply after understanding and truth.

As an interesting aside, Dr. Howard Hodis of the University of Southern California and an expert in carotid scanning for heart disease prevention research, made a comment relevant to us in the Track Your Plaque program:

"Clearly, progression of atherosclerosis is the only way you get events,” Dr. Hodis said. “If you don’t treat progression, then you get events."

Dr. Arthur Agatston in the news



The Miami Herald has a new report on Dr. Arthur Agagtston (of South Beach Diet fame) to announce his new book, The South Beach Heart Health Revolution:
The South Beach Diet doctor takes on cardio care

Agatston, the granddaddy of CT heart scanning, is always at least worth listening to. Although his diet may not be perfect, it clearly has jumped light years ahead of conventional diets like the inane American Heart Association diet. The South Beach Diet focuses on healthy oils, nuts, lean meats, vegetables, and fruits, while slashing grains (except in the often disastrous phase III).

The article lists Dr. Agatston's advice to achieve a "heart healthy" lifestyle:


• Maintain a healthy weight through diet.

• Undergo CT heart scans to check for arterial plaque.

• Do aerobic exercise, along with stretching and strengthening workouts.

• Ask your doctor about taking statins and other cholesterol-lowering drugs.


We wouldn't have CT heart scan scoring (at least in its present form) without Dr. Agatston, who developed the algorithm for scoring years ago in the early days of heart scanning. We also need to credit him with putting together a rational diet despite the counter-information emanating from the Heart Association, the USDA (a la Food Pyramid, the one that makes Americans fat and diabetic), and the American Diabetes Association, among others.

But "Ask your doctor about taking statins and other cholesterol-lowering drugs"? This is where Dr. Agatston begins to falter. While he is putting his enormous notoriety to use, his message is bland and ineffective. "Do aerobic exercise"? We don't need Dr. Agatston to tell us this.

As much as Art Agatston has added to the national conversation on heart disease and diet, he has failed to deliver the message of true heart disease prevention. His approach lacks just a few crucial ingredients like lipoprotein testing, diagnosis of hidden causes of heart disease (like Lp(a)), and vitamin D. (Two years ago I had a patient I saw for an opinion after he'd showed Dr. Agatston his lipoprotein panel. The patient said Dr. Agatston looked at the report and didn't know what to do with it and handed it back to him without comment. He then asked if he wanted his autograph.)

Anyway, the rising tide raises all boats. Agatston's repeated public endorsements of heart scans will help deliver the message that heart disease is detectable in its early stages and should trigger action to follow a heart disease prevention program.

That alone is an accomplishment in a world hell-bent on dragging us into the hospital for procedures.

Take this survey: I DOUBLE-DARE YOU

In a previous post I entitled Heart disease reversal a big "No No", I posed a challenge--a dare--to readers to ask their doctors if coronary heart could be reversed.

Here's what I said:

I dare you: Ask your doctor whether coronary heart disease can be reversed.

My prediction is that the answer will be a flat "NO." Or, something like "rarely, in extraordinary cases," kind of like spontaneous cure of cancer.

There are indeed discussions that have developed over the years in the conventional scientific and medical literature about reversal of heart disease, like Dean Ornish's Lifestyle Heart Trial, the REVERSAL Trial of atorvastatin (Lipitor) and the ASTEROID Trial of rosuvastatin (Crestor). Reversal of atherosclerotic plaque in these trials tends to be small in scale and sporadic.

The concept of reversal of heart disease has simply not gained a foothold in the lexicon nor in the thinking of practicing physicians. Heart disease is a relentlessly, unavoidably, and helplessly progressive disease in their way of thinking. Perhaps we can reduce the likelihood of cardiovascular events like heart attack and death with statin drugs and beta blockers. But reverse heart disease? In your dreams!

We need to change this mentality. Heart disease is a reversible phenomenon. Atherosclerosis in other territories like the carotid arteries is also a reversible pheneomenon. Rather than throwing medicines and (ineffective) diets at you (like the ridiculous American Heart Association program), what if your doctor set out from the start not just to reduce events, but to purposefully reduce your heart's plaque? While it might not succeed in everyone, it would certainly change the focus dramatically.

After all, isn't this the theme followed in cancer treatment? If you had a tumor, isn't cure the goal? Would we accept an oncologist's advice to simply reduce the likelihood of death from cancer but ignore the idea of ridding yourself completely of the disease? I don't think so.

Then why accept "event reduction" as a goal in heart disease? We shouldn't have to. Heart disease reversal--elimination--should be the goal.


I know of one person who actually followed through on this challenge and asked his cardiologist whether his heart disease could be reduced or reversed. As predicted, the answer was no. No explanation followed.

But allow me to reiterate: Heart disease is 1) detectable, 2) quantifiable, 3) controllable, and, in many cases 4) reversible.

What if there was a big payoff to your doctor if heart disease was reversed, say $100,000? That's enough to dwarf the payoff from procedures. Guess what? You'd have doctors fighting for your business, a chance to reverse your disease, ads to that effect, champions of reversal emerging. No new tools would be necessary. They could use the tools already available. Then why hasn't this happened? Is the technology unavailable? Are the treatments ineffective?

No, heart disease is a controllable and reversible process with tools that are available today. But there is, of course, no big payoff for doing it. So the financial incentive remains to do procedures, not to reverse the disease.

But I'd like to re-pose this challenge. Ask your doctor if heart disease can be reversed, or at least reduced. I've even posted a Survey at the top left for anyone who tries.

Again, my prediction: Nobody will try it and nobody will post survey results. Why? Despite my rantings (and those of a few others) about the concept of heart disease being a reversible process, in the public's consciousness it remains a death sentence and the only solution is hospital procedures. My colleagues continue to cultivate this attitude and it serves them well financially.

I'll be disappointed if I prove to be right. I hope that I am wrong. But I don't think that I am.

Michael Pollan on Nutritionism



The wonderfully articulate Michael Pollan has written another book. Although he presents little new to anyone who read his previous book, The Omnivore's Dilemma: A natural history of four meals, he is such a wonderful writer, with such clever ways of seeing the world, that I couldn't resist this new, less ambitious book.

The new book is In Defense of Food: An eater's manifesto.

As in Omnivore's Dilemma, Pollan reminds us that we've lost contact with real food, foods that our great grandmother would recognize, not the just-add-water, dried, pulverized, sweetened, high-fructose, hydrogenated, shrink-wrapped, artificially-colored products that pass as foods in the grocery store.

In particular, Pollan attacks what he calls the ideology of Nutritionism. "The widely shared but unexamined assumption is that the key to understanding food is indeed the nutrient. Put another way: Foods are essentially the sum of their nutrient parts." He calls this "Nutritionism."

In the section called "Nutritionism comes to market," he uses margarine as the prototypical product of this philosophy:

"No idea could be more sympathetic to manufacturers of processed foods, which surely explains why they have been so happy to jump on the nutritionism bandwagon. Indeed, nutritionism supplies the ultimate justification for processing food by implying that with a judicious application of food science, fake foods can be made even more nutritious than the real thing. This of course is the story of margarine, the first important synthetic food to slip into our diet. Margarine started out in the nineteenth century as a cheap and inferior sustitute for butter, but with the emergence of the lipid hypothesis in the 1950s, manufacturers quickly figured out that their product, with some tinkering, could be marketed as better--smarter!--than butter: butter with the bad nutrients removed (cholesterol and saturated fats) and replaced with good nutrients (polyunsaturated fats and then vitamins). Every time margarine was found wanting, the wanted nutrient could simply be added (Vitamin D? Got it now. Vitamin A? Sure, no problem. But of course margarine, being the product not of nature but of human ingenuity, could never be any smarter than the nutritionists dictating its recipe, and the nutritionists turned out to be not nearly as smart as they thought. The food scientists' ingenious method for making healthy vegetable oil solid at room temperature--by blasting it with hydrogen--turned out to produce unhealthy trans fats, fats that we now know are more dangerous than the saturated fats they were designed to replace. Yet the beauty of a processed food like margarine is that it can be endlessly reengineererd to overcome even the most embarrassing about-face in nutritional thinking--including the real wincer that its main ingredient might cause heart attacks and cancer. So now the trans fats are gone, and margarine marches on, unfazed and apparently unkillable. Too bad the same cannot be said of an unknown number of margarine eaters."


Anyone who reads and thinks a lot about nutrition will find little new here. But nobody says it better than Pollan. While Gary Taubes (Good Calories, Bad Calories) is the real thinker of our age about nutrition, Michael Pollan is the true writer about it.

With books like these making the bestsellers list, I believe that we are gradually seeing rationality return to eating. It makes people skeptical of the glitzy ads that run on TV around the clock. I hope that Pollan's new book will make more and more people leery of the latest health claim that adorn some product. "More omega-3!" "A low-fat snack." "Heart Healthy!" "High in healthy fiber!"

Cholesterol follies

Rudy is a 59-year old man. He's had three heart catheterizations, two of which resulted in stent implantations. Obviously, Rudy should be the beneciary of a prevention program.

His basic cholesterol values:

Total cholesterol 164 mg/dl--pretty good, it seems.

LDL cholesterol 111 mg/dl--Wow! Not too bad.

HDL cholesterol 23 mg/dl--Uh oh, that's not too good.

Triglycerides 148 mg/dl--By national (NCEP ATP-III) guidelines, triglycerides of 150 mg/dl and below fall within the desirable range.


So we're left with an apparently isolated low HDL cholesterol, nothing more. On the surface, it doesn't seem all that bad.

Of course, we need to keep in mind that this pattern landed Rudy in the hospital on several occasions and prompted several procedures.

Should we rely on these results? How about Rudy's lipoproteins?

Here they are (NMR; Liposcience):

LDL particle number 2139 nmol/l--Representing an effective LDL of 213--over 100 mg higher than the standard value (above) suggests.

Small LDL particles 2139 nmol/l--In other words, 100% of all Rudy's LDL particles are small. (Thus, weight-based measures of LDL cholesterol fail to tell us that he has too many small particles.)

Large HDL 0 (zero) mg/dl--Rudy has virtually no functional HDL particles.


If we had relied only on Rudy's standard cholesterol values, we would have focused on raising HDL. However, lipoprotein analysis uncovered a smorgasbord of additional severe patterns. The high LDL particle number comprised 100% of small particles is especially concerning.

Truly, conventional cholesterol testing is a fool's game, one that time and again fails to fully uncover or predict risk for heart disease. One look at Rudy's lipoproteins and it becomes immediately obvious: This man is at high risk for heart disease and the causes are clear.

Of course, many physicians and insurance companies argue that the added information provided by this portion of the lipoprotein test added around $70 more to the expense.

When you see results like this, is there even a choice?

Equal calories, different effects

A great study was just published in the Journal of the American College of Cardiology:

Metabolic effects of weight loss on a very-low-carbohydrate diet compared with an isocaloric high-carbohydrate diet in abdominally obese subjects.

88 obese adults with metabolic syndrome were placed on either of two diets:

1) A very low-carbohydrate, high-fat diet (VLCHF): 4% calories from carbohydrates (truly low-carb); 35% protein; 61% fat, of which 20% were saturated. In the first 8 weeks, carbohydrate intake was severely limited to <20 grams per day, then <40 grams per day thereafter.

2) A high-carbohydrate, low-fat diet (HCLF): 46% calories from carbohydrates; 24% protein; 30% total fat, of which <8% were saturated.

Both diets were equal in calories (around 1400 calories per day--rather restrictive) and participants were maintained on the program for six months.

At the end of the six month period, participants on the VLCHF diet lost 26.4 lb, those on the HCLF diet 22.2 lbs (though the difference did not reach statistical significance). Thus, both approaches were spectacularly successful at weight loss.

Surprisingly, blood pressure, blood sugar, insulin and insulin sensitivity (a measure called HOMA) were all improved with both diets equally. Thus, these measures seemed to respond more to weight loss and less to the food composition.

Lipids differed between the two diets, however:


VLCHF:
Total cholesterol: initial 208.4 mg/dl final 207.7 mg/dl

LDL: initial 125 mg/dl final 123 mg/dl

HDL: initial 55 mg/dl final 64.5 mg/dl

Triglycerides: initial 144 mg/dl final 74 mg/dl

Apoprotein B: initial 98 mg/dl final 96 mg/dl


HCLF
Total cholesterol: initial 208.4 mg/dl final 187.5 mg/dl

LDL: initial 126 mg/dl final 108 mg/dl

HDL: initial 51 mg/dl final 54.5 mg/dl

Triglycerides: initial 157.6 mg/dl final 111 mg/dl

Apoprotein B: initial 100 mg/dl final 95 mg/dl


Some interesting differences became apparent:
--The VLCHF diet more effectively reduced triglycerides and raised HDL.
--The HCLF diet more effectively reduced total and LDL.
--There was no difference in Apo B (no statistical difference).

The investigators also made the observation that individual responsiveness to the diets differed substantially. They concluded that both diets appeared to exert no adverse effect on any of the parameters measured, both were approximately equally effective in weight loss with slight advantage with the carbohydrate restricted diet, and that lipid effects were indeed somewhat different.


What lessons can we learn from this study? I would propose/extrapolate several:

When calories are severely restricted, the composition of diet may be less important. However, when calories are not so severely restricted, then composition may assume a larger role. When calories are unrestricted, I would propose that the carbohydrate restriction approach may yield larger effects on weight loss and on lipids when compared to a low-fat diet.

The changes in total cholesterol are virtually meaningless. Part of the reason that it didn't drop with the VLCHF diet is that HDL cholesterol increased. In other words, total cholesterol = LDL + HDL + trig/5. A rise in HDL raises total cholesterol.

Despite no change in Apo B, if NMR lipoprotein analysis had been performed (or other assessment of LDL particle size made), then there would almost certainly have seen a dramatic shift from undesirable small LDL to less harmful large LDL particles on the VLCHF diet, less change on the HCLF diet.

The lack of restriction of saturated fat in the VLCHF that failed to yield adverse effects is interesting. It would be conssistent with the re-analysis of saturated fat as not-the-villain-we thought-it-was put forward by people like Gary Taubes (Good Calories, Bad Calories).

In the Track Your Plaque experience, small LDL is among the most important measures of all for coronary plaque reversal and control. Unfortunately, although this study was well designed and does add to the developing scientific exploration of diet, it doesn't add to our insight into small LDL effects. But if I had to make a choice, I'd choose the low-carbohydrate, high-fat approach for overall benefit.

Is skinny necessary for reversal?

Nothing we do in the Track Your Plaque program guarantees that coronary atherosclerotic plaque or your heart scan score is reduced or reversed.



But everything we do weighs the odds in your favor of successfully achieving reversal: correction of lipoprotein patterns, uncovering hidden patterns like Lp(a), vitamin D, being optimistic--it all tips the scales in your favor.

But how necessary is it to be skinny, meaning somewhere near your ideal weight?

It is important, but not as important as it used to be. Let me explain.

I used to tell people that plaque would not regress unless ideal weight was achieved and all the parameters of abdominal obesity and metabolic syndrome were corrected. This includes blood pressure, blood sugar, low HDL, small LDL, high triglycerides, and high c-reactive protein. Curiously, though, as we've gotten better and better at reducing coronary calcium scores, I've been finding that complete correction of all parameters, including achieving ideal weight, don't seem to be as necessary to achieve plaque reversal.

I almost hate to say this, but I've even witnessed significant drops in heart scan scores in people with body mass indexes (BMI) of 30--obese.

The necessary change doesn't seem to be weight, per se, but the consequences of weight. In other words, if you remain overweight, but blood sugar, HDL, small LDL, etc. have shown substantial improvement, then reversal is still achievable.

Then is it okay to be fat or overweight?

Reducing weight to ideal weight does indeed tip the scales in your favor, since it represents an observable, perceptible measure of all associated patterns. Dropping weight can also minimize the need for efforts to correct the consequences of overweight--you might need less niacin, fish oil, exercise, blood pressure medication, etc. to succeed at plaque reversal. Achieving ideal weight may also provide benefits like reduced risk of cancers and degenerative diseases of the hips and knees. But, to my recent surprise over the last two years, achieving ideal weight is not an absolute requirement to achieve reversal.

This is contrary to what some others say. For instance, in an upcoming interview with Dr. Joel Fuhrman on the Track Your Plaque website, Dr. Fuhrman argues that 10% body fat for males, 22% body fat for females, accelerates plaque and symptom reversal. Dr. Fuhrman is author of Fasting and Eating for Health, Eat to Live, and a new upcoming 2-part book, Eat for Health, and proponent of high-nutrient vegetarian diets and fasting. Dr. Fuhrman has been helpful in teaching us some important lessons on how to apply periodic fasting to accelerate plaque reversal.

So, which is it, fat or skinny?

If given a choice (which everyone has), I'd choose skinny. But, provided all the parameters associated with overweight are corrected, then remaining overweight doesn't necessarily mean that you can't still succeed at plaque reversal.

If you are interested in knowing what your ideal weight is, there are a number of software calculators and tables available, including the HealthCentral.com calculator and the National Heart, Lung, and Blood Institute BMI Calculator.

MESA Study: Track Your Plaque-Lite?

The long-awaited data analyses from the Multi-Ethnic Study of Atherosclerosis (MESA) are finally making it to press.

The MESA Study is an enormously ambitious and important study of 6800 people, 45 to 84 years old, that includes white, black, Hispanic, and Chinese participants from six communities around the U.S. (Forsyth County, NC; Northern Manhattan and the Bronx, NY; Baltimore and Baltimore County, Md; St Paul, Minn; Chicago, Ill; and Los Angeles County, California.) Participants had no history of heart disease at enrollment. All underwent a heart scan (either EBT or multi-detector heart scans) at the start. It is therefore the largest prospective study involving heart scans ever performed. It is, not unexpectedly, yielding some fascinating observations relevant to the Track Your Plaque program. The MESA study is, incidentally, funded by the non-commercial, publicly-funded National Heart, Lung, and Blood Institute and is therefore presumably free of commercial bias.

Among the most recent publications is Risk factors for the progression of coronary artery calcification in asymptomatic subjects: Results from the Multi-Ethnic Study of Atherosclerosis (MESA) In this analysis of 5700 of the MESA participants, a repeat heart scan was obtained an average of 2.4 years after the first. Conventional risk factors for heart disease were obtained at the start (see below for details under Measurement of Covariates.)

After analyzing the data and risk factors assessed, such as age, sex, race, blood pressure, body mass index (BMI), presence of diabetes, blood sugar, and family history of heart disease, two questions were asked:

1) What risk factors predict heart scan scores?

2) What risk factors predict progression (i.e., increase) in heart scan scores?

(The second question is particularly relevant to us and the Track Your Plaque experience.)

The MESA analysis showed that essentially all the risk factors assessed correlated with both the initial heart scan score, as well as the rate of progression. No surprises here.

But the most eye-opening finding was that the conventional risk factors assessed explained only 12% of the variation and progression in heart scan scores (coefficient of determination, or R squared, = 0.12.) In other words:

--Conventional risk factors like LDL cholesterol, diabetes, and excess weight explain only a tiny fraction of why someone develops coronary atherosclerotic plaque as represented by a heart scan score.

--The great majority of risk for a high heart scan score remains unexplained by conventional risk factors.

--The great majority of risk for progressive increase in heart scan scores also remains unexplained by conventional risk factors.


In light of the MESA analysis, it's no surprise that strategies like reducing LDL cholesterol with statin drugs fails to prevent most heart attacks. It's no surprise that conventional prevention programs that talk about "knowing your numbers," eating a "balanced" or low-fat diet, etc., fail miserably to prevent the vast majority of heart attacks and heart procedures.

MESA confirms what we've been saying these past few years: If you want control over coronary heart disease, you won't find it in Lipitor, a low-fat diet, and other limited conventional notions of risk. Correction of conventional risk factors like cholesterol and blood pressure are, in a word, a failure. I wouldn't even call the conventional approach Track Your Plaque-Lite. They don't even come close.

If conventional risk factors can explain only 12% of the reason behind heart disease, we've got to look elsewhere to understand why you and I develop this process.



Measurement of Covariates
Information on demographics, smoking, medical conditions, and family history was collected by questionnaire at the initial examination. Height and weight were also measured at the baseline examination, and blood was drawn for measurements, including lipids, inflammation, fasting glucose, fibrinogen, and creatinine. Resting blood pressure was measured 3 times in the seated position, and the average of the last 2 measurements was used in the analysis. Medication use was determined by questionnaire. Additionally, the participant was asked to bring to the clinic containers for all medications used during the 2 weeks before the visit. The interviewer then recorded the name of each medication, the prescribed dose, and frequency of administration from the containers.
