"I have never seen regression"

At a presentation at the American College of Cardiology meetings in New Orleans yesterday (March 27, 2007), Dr. Arthur Agatston declared "I have been doing CT for many years, and I have never seen regression."

Whooooaaaa. Wait a minute here. I have great respect for the work Dr. Agatston has done over the years. He is, after the originator of the scoring algorithm that allows us to score CT heart scans (though a more accurate measure, the volumetric score, is the one we often use behind closed doors because of modestly increased accuracy and reproducibility). His diet program, the South Beach Diet, has achieved enormous success and is indeed an effective approach for both weight loss and correction of many weight-related causes of heart disease.

But he has never seen regression? Why would this be when we see it all the time? When we see heart scan scores drop 30%, it's hard to believe that with some savvy he has never seen regression (drop in score).

I can only attribute the difference to the more intensive endpoints we advocate (e.g., 60-60-60 for lipid values); the incorporation of adjuncts like fish oil, vitamin D, l-arginine; attention to non-cholesterol issues and intensified treatments for each. I doubt that the populations we see differ substantially.

As much as I admire Dr. Agatston's accomplishments, I believe that he is behind the times on this issue. No regression is so starkly different from the Track Your Plaque experience. I believe that relying only on statin drugs and diet will slow but will not stop plaque growth. It will also rarely, if ever, drop your score.

Attention to detail and a little insight into better preventive strategies really pays off. While not everyone in the Track Your Plaque experience will drop their score, a substantial number do. Many more slow plaque growth dramatically. And, as time goes on, our track record gets stronger and stronger.

COURAGE to do better

The results of the long-awaited COURAGE Trial were announced today at the American College of Cardiology meetings in New Orleans.

In this trial, 2200 participants with stable coronary disease (i.e., not unstable, in which heart attack or death is imminent) were randomly assigned ("randomized") to either angioplassty/stent or "maximal medical therapy." Medical therapy means such things as aspirin, beta blocker drugs, and statin cholesterol drugs. There was virtually no difference between the groups in rate of heart attack and death from heart disease over a period of up to 7 years.

These results have caused a stir in the media and my colleagues, trying to sort out of the implications. However, I think there's one observation in particular worth making for those of us who tend to scoff at the conventional approach to coronary disease. That is, 1 of 5 people had a heart attack or died from heart disease in both groups. That's a lot. Even more ended up with a procedure (angioplasty, stent, or bypass). In other words, the "maximal medical therapy" instituted in participants was hardly a success. Though angioplasty and stenting failed to prove superiority, both really stunk. Both permitted a lot of catastrophes to occur.

"Maximal medical therapy," in other words, is a laughable concept. It doesn't include raising HDL, suppressing small LDL, reducing Lipoprotein(a), addressing inflammatory issues. It does not include omega-3 fatty acids from fish oil, nor does it address the severe degrees of vitamin D deficiency that are proving, in the Track Your Plaque experience, to be among the most potent causes of atherosclerotic plaque known. It includes a sad attempt at diet, as advocated by the American Heart Association, a diet that, in my view, causes heart disease and is distorted by the powerful political and financial influence of food manufacturers.

If the trial were to be done again, I'd like to see the "maximal medical therapy" arm be represented by a more effective program like the Track Your Plaque approach.

Value of a zero heart scan score

Margaret is 73. She's a very good 73. She loves children and works full-time in a daycare. She manages her own household, goes to dinner at least once each week with one or more of her adult children. She is slender and has never been in the hospital--until she developed an abnormal heart rhythm called atrial fibrillation.

Most people who develop atrial fibrillation do so with no immediate identifiable cause. However, Margaret has been a widow since her husband died 15 years ago of a heart attack. She was therefore especially frightened of any heart issues in her own health. Her doctor also raised the question of whether atrial fibrillation might represent the first hint of future heart attack.

So we advised a CT heart scan. Score: zero, or no detectable plaque whatsoever. This put Margaret's risk for heart attack as close to zero as humanly possible. (Nobody is truly at zero risk for heart attack for a number of reasons. One reason is that people do irrational things like take cocaine or amphetamines, or they take too much decongestant medication, all of which can trigger heart attack.)

The heart scan settled it. Margaret has the sort of atrial fibrillation which likely simply develops as a result of "wear and tear" on the heart's electrical impulse conducting system and it has nothing to do with coronary heart disease or heart attack.

As that MasterCard commercial goes: Cost of a heart scan: About $200. Peace of mind: priceless.

You're at the cutting edge

If you're a participant in the Track Your Plaque program for atherosclerotic plaque regression, you are at the cutting edge of health.

Few physicians give this issue any thought. Chances are, for instance, that if you were to bring up the subject of reversal of heart disease to your primary care physician, you'd get a dismissive "it's not possible," or " Yeah, it's possible but it's rare."

Ask a cardiologist and you might make a little more progress. He/she might tell you that Lipitor 80 mg per day or Crestor 40 mg per day might achieve a halt in plaque growth or a modest reduction of up to 5-6%. If they've tried this strategy, they would likely also tell you that hardly anybody can tolerate these doses for long due to muscle aches. I'd estimate that 1 of 10 of my colleagues would even be aware of these studies.

Both groups are, however, reasonably adept at diagnosing chest pain, an everyday occurrence in hospitals and offices. Chest pain, for them, is a whole lot more interesting. It holds the promise of acute catastrophe and all its excitement. It also holds the key to lots of hospital revenues. Did you know that 80% of all internal medicine physicians are now employees of hospitals? They're also commonly paid on an incentive basis. More revenues, more money.

Ask Drs. Dean Ornish or Caldwell Esselstyn about reversal of heart disease and they will tell you that a very low-fat diet (<10% of calories)can do it. That's true if you use a flawed test of coronary disease like heart catheterization (angiograms) or nuclear stress tests (Ornish calls them "SPECT"). It would be like judging the health of the plumbing in your house by the volume of water flowing out the spigot. It flows even when the pipes are loaded with rust.

In the Track Your Plaque experience, extreme low-fat diets (i.e., high wheat, corn, and rice diets) grotesquely exagerrate the small LDL particle size pattern, among the most potent triggers for coronary plaque growth. This approach also makes your abdomen get fatter and fatter and inches you closer to diabetes. Triglycerides go up, inflammation increases.

If you were able to measure the rust in the pipes, that would be a superior test. You can measure the "rust" in your "pipes," the atherosclerotic plaque in your coronary arteries, using two methods: CT heart scans or intracoronary ultrasound. Take your pick. I'd choose a heart scan. It's safe, accurate, inexpensive. I've performed many intracoronary ultrasounds for people in the midst of heart attacks or some other reason to go to the catheterization laboratory. But for well people, without symptoms, who are interested in identifying and tracking plaque? That's the place for heart scans.

In our program, 18-30% reductions in heart scan scores are common.

A stent--just in case

Burt came to me last week. He'd received a stent a few months earlier. He'd been feeling fine except for some fatigue. A nuclear stress test proved equivocal, with the question of an abnormal area of blood flow in the bottom (inferior wall) of the heart.

"The doctor said I had a 50% blockage. Even though it wasn't really severe, he said I'd be better off with a stent, just in case."

Just in case what? What justification could there be for implanting a stent "just in case"? (The artery that was stented did not correspond to the area of questionable poor blood flow on the nuclear stress test.)

Just in case of heart attack? If that's the case, what about the several 20 and 30% blockages Burt showed in other arteries? The cardiologist was apparently trying to prevent the plaque "rupture" that results in heart attack by covering it with a stent. Why stent just one when there were at least 7 other plaques with potential for rupture?

That's the problem. And that's why stents do not prevent heart attack (unless the stent is implanted in the midst of heart attack, when the rupturing plaque declares itself.) Of course, when no plaque is in the midst of rupturing, as with Burt, there's no way to predict which plaque will do so in future. Since only one plaque was stented, there is a 7 out of 8 chance (87.5%) that the wrong plaque was chosen. And that's assuming that there aren't plaques not detected by catheterization angiogram; there commonly are. The odds that the right plaque was chosen would be even lower.

In other words, stenting one blockage that is slightly more "severely blocked" in the hopes of preventing heart attack is folly. If it's not resulting in symptoms and blood flow is not clearly reduced, a stent can not be used to prevent plaque rupture. A stent is not a device to be used prophylactically. It is especially silly when an approach like ours is followed, since plague progession is a stoppable process.

Note: This issue is distinct from the one in which symptoms and/or an abnormal stress test show clearly reduced blood flow and flow is restored by implantation of a stent. While some controversies exist here, as well, a stent implanted under these circumstances may indeed provide some benefit.

How will you know your score dropped?

This issue came up twice this week.

Bill is a busy accountant. Two years ago, just after the tumult of the 2005 tax season was over, he got a CT heart scan. His score: 398. At age 53, this was a significant score. His internist did the usual: prescribed a statin (Zocor), told him to cut the fat in his diet, and be sure to exercise. (Yawn.)

Since then, Bill quit preparing tax returns and migrated to a less harried job in corporate accounting. It took two years since his heart scan for Bill to start thinking that perhaps his doctor's advice wasn't enough. If it was, he realized, everyone on a statin drug who made these minimal lifestyle changes would be cured of heart attack risk. Clearly not the case.

So Bill enrolled in the Track Your Plaque program. Our first step: Get another heart scan.

Bill was surprised. "Why another scan? I already had one!"

I explained to Bill that atherosclerotic plaque is like money: it grows in percentages, just like money in a bank account or in a mutual fund. If, for instance, you deposit $500 in a mutual fund and it yields 5% return, then after one year you will have $550. One year later, you will have 5% x $550, or $605. Another year: $665. In other words, growth is not 10% of the original amount you deposited. Growth is compounded, year over year. That's why money, when compounded, can grow so quickly.

Atherosclerotic plaque and your CT heart scan score do the same thing: they grow by a percentage of the current plaque quantity. In fact, we use the compound interest equation to calculate the annualized rate of plaque growth. But plaque grows at the extraordinary rate of 30% per year, on average. Imagine that was the rate of return on your money. You'd be the richest man or woman on earth.

Back to Bill. Now Bill, in his defense, was on a statin drug and did make modest efforts towards a (mis-guided) low-fat diet and walking four days per week. If, on a second CT heart scan, his score was:

398--No change. That's a success, since the expected rate of increase of 30% has been stopped. However, on his current program, this is highly unlikely. (I've seen it happen just once ever out of about 2000 people.)

250--Pop the cork on your champagne, because Bill needs to celebrate. He has substantially reversed his plaque. Highly unlikely on the current effort.

525 --The score is higher by 30%, so it has slowed, but it surely hasn't stopped. This is the most typical result on the sort of program Bill is following.

The message: Don't delay after your first heart scan score. It plaque grows like money with a huge return, there's no time like the present to take the steps to regain control.

Firefighters Face Added Risk of Fatal Heart Attack

Firefighters are twice as likely to die from a heart attack in the line of duty than are policemen, and three times more likely than EMTs.

That's among the headlines run today because of a report in the New England Journal of Medicine documenting a dramatically higher risk for heart attack for fire fighters putting out fires. The above headline is from an excellent report run on NPR radio. You can listen to the webcast at http://www.npr.org/templates/story/story.php?storyId=9047656.

The story sparked comments from experts insisting that all fire fighters should have physicals, should be in better physical condition, should be covered by health insurance (the NPR report said that 1 out of 4 fire fighters lack health insurance). Judging from the indisputable risk firefighters encounter, these are all good ideas.

But if you've been following my blog or the Track Your Plaque program, you know that physicals alone are hopeless exercises for identifying hidden heart disease. Among the solutions: identify whether or not heart disease is present in the first place--do a CT heart scan.

In fact, several local fire companies in my area have done just that: insisting that all firefighters undergo a heart scan. When groups of people like firefighters arrange for heart scans, they gain the advantage of doing so en masse, thereby allowing many scan centers to offer a dramatically reduced price to the city, town, or village that is paying for them. I've even seen many firefighters scanned at no cost.

It would also help to have health insurance, be physically fit, and have a stress test (an exception to my view that stress tests are also useless to screen asymptomatic people for heart disease). But a CT heart scan would settle the question quickly, easily, undeniably, and inexpensively.

Prophylactic bypass surgery?

This question comes up around once a week:

My CT heart scan score is ____. Wouldn't I be better off just getting a bypass (or stent, etc.) and getting it over with? If I know that heart attack is in my future, why not just get it over with?

The most recent source of this question was the wife of a patient. Jack had a heart scan score of 92 in 2005. He made very little effort to correct his causes, permitting pre-diabetic patterns to persist, failed to correct vitamin D, etc. and a repeat heart scan score showed a dramatic rise to 264.

Jack's wife asked whether he should just have a bypass.

There are several problems with this line of reasoning:

1) Bypass surgery does not reduce the long term risk for heart attack.

2) The risk of bypass surgery often outweighs the risk of an asymptomatic heart scan score.

3) Bypass surgery is a temporary "fix," a fancy Band Aid for a disease that progresses after the procedure. One bypass typically prompts another, and another...

4) Bypassing arteries that have vigorous blood flow often causes the bypass graft to not "take" and close within the first few days.


Thankfully, nobody in his right mind has proposed that we perform prophylactic bypass operations.

Of course, hospitals and surgeons would jump at the chance to perform procedures in anybody with some threshhold heart scan score. It would double or triple their business overnight. At $70,000 or more per procedure, they would dance in glee. Of course, you and I would pay for their new burst of wealth by a sharp increase in our health insurance premiums. Not only that, the people who underwent the procedure would not benefit.

Lipitor 80 mg

I'm seeing more and more people taking 80 mg of Lipitor per day. For the most part, these are people who come in for another opinion after a stent or heart attack and are prescribed the drug during their hospitalization.

This practice is based on the results of the PROVE IT-TIMI 22 (PRavastatin Or atorVastatin Evaluation and Infection Therapy-Thrombolysis In Myocardial Infarction) trial, and the Reversal of Atherosclerosis with Aggressive Lipid Lowering (REVERSAL) trial, both reported in 2005. In the PROVE IT Trial, 4,000 people experiencing heart attacks were treated with Lipitor (atorvastatin), 80 mg, or Pravachol (pravastatin), 40 mg. There was a reduction in events like recurrent heart attack from 13.1% in the Pravachol group to 9.6% in the Lipitor group. In the REVERSAL Trial, the Lipitor group also showed no plaque growth compared to the Pravachol group, which did progress, with disease tracked by intracoronary ultrasound.

I believe that many of my colleagues took the bait. In a half-hearted effort to reduce events and trend towards better coronary plaque control, writing a prescription for 80 mg rather than a lower dose has become increasingly popular.

Some problems: Despite the favorable tolerance to high dose Lipitor in these trials, I don't know anybody who can tolerate 80 mg per day for more than a few months in real life. In my experience, people inevitably end up with intolerable muscle aches.

Also, I believe it is folly to believe that we can regress coronary plaque on a broad scale by just using one drug that addresses only a single cause (i.e., LDL cholesterol). Yes, drug companies would argue that the statin drugs are so wonderful because of their so-called "pleiotropic", or non-lipid, effects like reducing inflammation. I have seen regression of plaque once using Lipitor alone. We struggle to reduce coronary plaque using a multi-faceted approach. It is highly unlikely that Lipitor alone at a 80 mg dose will be sufficient in most people to regress plaque. How about lipoprotein(a)? Or vitamin D deficiency? Lipitor has no effect on these patterns and people do not regress just by taking statin agents.

Orlistat for weight loss

In early February, the FDA approved orlistat, formerly known as prescription Xenical, for over-the-counter sale. Orlistat is a blocker of fat absorption.

The new OTC version will be called "Alli" (pronounced like "ally") and will come at a dose of 60 mg to be taken three times a day with meals. Prescription Xenical came as a 120 mg tablet. However, the company claims that the reduced dose sacrifices only 5% in reduced fat absorption, dropping from 30% with Xenical to 25% with Alli. It will cost in the neighborhood of $1 to $2 per day, or $30-60 per month, far less expensive than the $110-150 for the prescription form.

Does it work? Is it worth the money? Clinical trials document around 5-10 lbs lost over a 3 to 6 month period, 50% greater than using diet and exercise alone.

Our experience is that it works, though inconsistently. Results depend heavily on how reliant you are on fat calories. If you were to follow a low-fat diet while on the drug, you likely will lose little or no weight, since there's little fat absorption to block. However, I have witnessed more substantial weight loss of 10-20 lbs. in people who follow a higher fat intake in their diet, e.g., a traditional American diet. However, these people gain the weight back immediately because they've made no effort to modify food choices.

It is messy. Even though the clinical trials claims modest inconvenient effects like gas and greasy stools, I have found that it is, without fail, a very annoying product that results in crampiness and frequent messy stools in nearly everybody.

The company has created a glitzy website that you can view at www.myalli.com and promises to provide a personalized program and support for registrants when it is up and running by summer 2007.
I think that's a good idea, since the drug itself is no more than a temporary fix unless it's combined with long-term diet changes. However, the website, I believe, oversells the value of the drug with a drug company's usual over-the-top hints and innuendoes without actually coming out with straight pitches of the truth.

Beware of the vitamin D-blocking effect of Orlistat. The period of time you take it may be a time to resort to some modest sun exposure (10-15 minutes; be careful not to burn), rather than than oil-based vitamin D capsules, in order to avoid the inevitable vitamin D plunge in blood level.

I am not a fan of orlistat, having seen it tried many times with minimal success. However, it is another option for those who are really struggling. Personally, I would try fasting or some of the other strategies we've detailed on the www.cureality.com website before I resorted to orlistat.

Restaurant eating: A fructose landmine

There is no remaining question that fructose is among the worst possible things humans can consume.

Followers of the Heart Scan Blog already know this, from conversations like The LDL-Fructose Disconnect, Where do you find fructose?, and Goodbye, fructose.

But fructose, usually as either high-fructose corn syrup (44%, 55%, occasionally higher percentage fructose) or sucrose (50% fructose), is ubiquitous. I've seen it in the most improbable places, including cole slaw, mustard, and dill pickles.

It's reasonably straightforward to avoid or minimize fructose exposure while eating at home, provided you check labels and focus on foods that don't require labels (like green peppers, salmon, and olive oil, i.e., unprocessed foods). But when you choose to eat at a restaurant, then all hell can break loose and fructose exposure can explode.

So what are some common and unsuspected fructose sources when eating at a restaurant?

Salad dressings--Dressings in all stripes and flavors are now made with high-fructose corn syrup and/or sucrose. This is especially true of low-fat, non-fat, or "lite" dressings, meaning oils have been replaced by high-fructose corn syrup. It can also be true of traditional non-low-fat dressings, too, since high-fructose corn syrup is just plain cheap.

Olive oil and vinegar are still your safest bets. I will often use salsa as a dressing, which works well.

Sauces and gravies--Not only can sauces be thickened with cornstarch, many pre-mixed sauces are also made with high-fructose corn syrup or sweetened with sucrose. Barbecue sauce is a particular landmine, since it is now a rare barbecue sauce not made with high-fructose corn syrup as the first or second ingredient. Sauces for dipping are nearly always high-fructose corn syrup-based.

Ketchup--Yup. Good old ketchup even is now made with high-fructose corn syrup. In fact, you should be suspicious of any condiment.

Highball, Bloody Mary, Margarita, Daiquiri, beer--Even the before-dinner or dinner drink can have plenty of fructose, particularly if a mix is used to make it. While Blood Marys seem the most benign of all, adorned with celery, pickle, and olive, just take a look at the ingredient label on the mix used: high-fructose corn syrup.

Fructose is a stealth poison: It doesn't immediately increase blood sugar; it doesn't trigger any perceptible effect like increased energy or sleepiness. But it is responsible for an incredible amount of the health struggles in the U.S., from obesity, to diabetes, to hyperlipidemias and heart disease, to arthritis, to cataracts.

A glycation rock and a hard place

Advanced Glycation End-products, or AGEs, the stuff of aging that mucks up brains, kidneys, and arteries, develop via two different routes: endogenous (from within the body) and exogenous (from outside the body).

Endogenous AGEs develop via glycation. Glycation of proteins in the body occurs when there are glucose excursions above normal. For instance, a blood glucose of 150 mg/dl after your bowl of stone-ground oatmeal causes glycation of proteins left and right, from the proteins in the lens of your eyes (cataracts), to the proteins in your kidneys (proteinuria and kidney dysfunction), to skin cells (wrinkles), to cartilage (brittle cartilage followed by arthritis), to LDL particles, especially small LDL particles (atherosclerosis).

At what blood sugar level does glycation occur? It occurs even at "normal" glucose levels below 100 mg/dl (with measurable long-term cardiovascular effects as low as 83 mg/dl). In other words, some level of glycation proceeds even at blood glucose levels regarded as normal.

There's nothing we can do about the low-level of glycation that occurs at low blood sugar levels of, say, 90 mg/dl or less. However, we can indeed do a lot to not allow glycation to proceed more rapidly, as it inevitably will at blood sugar levels higher than 90 mg/dl.

How do you keep blood sugars below 90 mg/dl to prevent excessive glycation? Avoid or minimize the foods that cause such rises in blood sugar: carbohydrates.

What food increases blood sugar higher than nearly all other known foods? Wheat.

Is einkorn the answer?

People ask: "What if I would like a piece of bread or other baked product just once in a while? What is safe?"

Eli Rogosa, Director of The Heritage Wheat Conservancy, believes that a return to the wheat of our ancestors in the Fertile Crescent, circa 10,000 years ago, is the answer.

Former science teacher, now organic farmer, farm researcher, and advocate of sustainable agriculture, Eli has been reviving "heritage" crops farmed under organic conditions, some of her research USDA-funded.

In particular, Eli has been cultivating original 14-chromosome ("diploid") einkorn wheat. Although einkorn contains gluten (in lesser quantities despite the higher total protein content), the group of proteins that trigger the immune abnormalities of celiac disease and other immune phenomena, Eli tells me that she has witnessed many people with a variety of wheat intolerances, including celiac disease, tolerate foods made with einkorn wheat. (The variety of glutens in einkorn differ from the glutens of the dwarf mutant that now dominate supermarket shelves.)

Eli travels to Israel every year, returning with "heritage" seeds for wheat and other crops. She formerly worked in the Israel GenBank as Director of the Ancient Wheat Program. She has written a brochure that describes her einkorn wheat.

Eli sent me 2 lb of her einkorn grain that nutritionist, Margaret Pfeiffer, and I ground into bread. Our experience is detailed here. My subsequent blood sugar misadventure, comparing einkorn bread to conventional organic whole wheat bread is detailed here, followed by the odd neurologic effects I experienced here.

Anyone else wishing to try this little ancient wheat experiment with einkorn can also obtain either the unground grain or ground flour through Eli's website, www.growseed.org. Most recently, einkorn pasta is being retailed under the Jovial brand at Whole Foods Market.

If anyone else makes bread or any other food with Eli's einkorn wheat, please let me know:

1) Your blood sugar response (before and 1 hour after consumption)
2) Whether you experienced any evidence of wheat intolerance similar to what you experienced with conventional wheat, e.g., rash, acid reflux, gas and cramping, moodiness, asthma, etc.

But remember: Wheat effects or no, einkorn is still a grain. My belief is that humans do best with little or no grain. The einkorn experience is an effort to identify reasonable compromises so that you and I can have a piece of birthday cake once a year without getting sick.

Genetic incompatibility

Peter has lipoprotein(a), or Lp(a), a genetic pattern shared by 11% of Americans.

It means that Peter inherited a gene that codes for a protein, called apoprotein(a), that attaches to LDL particles, forming the combined particle Lp(a). It also means that his overall pattern responds well to a high-fat, high-protein, low-carbohydrate diet: The small LDL particles that accompany Lp(a) over 90% of the time are reduced, Lp(a) itself is modestly reduced, other abnormalities like high triglycerides (that facilitate Lp(a)'s adverse effects) are corrected. Small LDL particles are, by the way, part of the genetic "package" of Lp(a) in most carriers.

Peter also has another gene for Apo E4, another genetically-determined pattern shared by 19% of Americans. (Another 2% of Americans have two "doses" of Apo E4, i.e., they are homozygotes for E4.) This means that the Apo E protein, normally responsible for liver uptake and disposal of lipoproteins (especially VLDL), is defective. In people with Apo E4, the higher the fat intake, the more LDL particles accumulate. (The explanation for this effect is not entirely clear, but it may represent excessive defective Apo E-enriched VLDL that competes with LDL for liver uptake.) People with Apo E4 therefore drop LDL (and LDL particle number and apoprotein B) with reductions in fat intake.

This is a genetic rock-and-a-hard-place, or what I call a genetic incompatibility. If Peter increases fat and reduces carbohydrates to reduce Lp(a)/small LDL, then LDL measures like LDL particle number, apoprotein B, and LDL cholesterol will increase. Paradoxically, sometimes small LDL particles will even increase in some genetically predisposed people.

If Peter decreases fat and increases carbohydrates, LDL particle number, apoprotein B, and LDL cholesterol will decrease, but the proportion of small LDL will increase and Lp(a) may increase.

Thankfully, such "genetic incompatibilities" are uncommon. In my large practice, for instance, I have about 5 such people.

The message: If you witness paradoxic responses that don't make sense or follow the usual pattern, e.g., reductions in LDL particle number, apoprotein B, and small LDL with reductions in their dietary triggers (i.e., carbohydrates, especially wheat), then consider a competing genetic trait such as Apo E4.

The folly of an RDA for vitamin D

Tom is a 50-year old, 198-lb white male. At the start, his 25-hydroxy vitamin D level was 28.8 ng/ml in July. Tom supplements vitamin D, 2000 units per day, in gelcap form. Six months later in January (winter), Tom's 25-hydroxy vitamin D level: 67.4 ng/ml.

Jerry is another 50-year old white male with similar build and weight. Jerry's starting summer 25-hydroxy vitamin D level: 26.4 ng/ml. Jerry takes 12,000 units vitamin D per day, also in gelcap form. In winter, six months later, Jerry's 25-hydroxy vitamin D level: 63.2 ng/ml.

Two men, similar builds, similar body weight, both Caucasian, similar starting levels of 25-hydroxy vitamin D. Yet they have markedly different needs for vitamin D dose to achieve a similar level of 25-hydroxy vitamin D. Why?

It's unlikely to be due to variation in vitamin D supplement preparations, since I monitor vitamin D levels at least every 6 months and, even with changes in preparations, dose needs remain fairly constant.

The differences in this situation are likely genetically-determined. To my knowledge, however, the precise means by which genetic variation accounts for it has not been worked out.

This highlights the folly of specifying a one-size-fits-all Recommended Daily Allowance (RDA) for vitamin D. The variation in need can be incredible. While needs are partly determined by body size and proportion body fat (the bigger you are, the more you need), I've also seen 105 lb women require 14,000 units and 320-lb men require 1000 units to achieve the same level of 25-hydroxy vitamin D.

An RDA for everyone? Ridiculous. Vitamin D is an individual issue that must be addressed on a person-by-person basis.

Heart scan: Standard of care?

If coronary disease is easy to detect by measuring coronary calcium, shouldn't this represent the standard of care?

In other words, if you've been seeing your doctor and he/she has been monitoring cholesterol levels and, inevitably, talks about statin drugs, then you have a heart attack, unstable angina, or die--yet never knew you had heart disease--isn't this negligence?

Coronary calcium, and thereby coronary atherosclerotic plaque, are markers for the disease itself. Unlike cholesterol, high blood pressure, etc., that represent risk factors for coronary atherosclerotic plaque, coronary calcium is a measure of total plaque: "soft" elements like lipid collections, necrotic tissue, fibrous tissue, as well as "hard" elements like calcium. Because calcium occupies 20% of total atherosclerotic plaque volume, it can be used as an indirect "dipstick" for total plaque.

So why isn't an unexpected heart attack, hospitalization for unstable heart symptions, emergency bypass, etc., not regarded as potential malpractice? These are not benign events, but potentially life-threatening.

The costs of doing drug business?
