Niacin scams

In the Track Your Plaque program, we often resort to niacin (vitamin B3 or nicotinic acid) to:

--Raise HDL cholesterol
--Reduce the proportion of small LDL particles
--Shift HDL towards the healthy larger fraction (HDL2b or "large")
--Reduce lipoprotein(a), the most aggressive risk factor known


But niacin comes with a crazy "hot flush," a warm, prickly feeling that usually envelops the upper chest, neck and face that is, without a doubt, annoying. Around 1 in 20 people simply cannot tolerate any amount of niacin >100 mg, while others have no problem even into the 3000 mg per day or more range. (Tolerance to niacin is genetically determined, governed by the rapidity of metabolism to the niacin metabolite, nicotinuric acid.)

The niacin flush has spawned an entire panel of niacin-like scams, agents that sound like niacin or may even contain niacin, but exert no beneficial effect whatsoever:

Flush-free niacin--I have previously posted on this useless but ubiquitous preparation that often costs several times more than conventional niacin. Flush-free niacin, or inositol hexaniacinate, does indeed contain niacin, but it is not released in the human body. You simply pass it out down the toilet, where this preparation belongs in the first place.

Nicotinamide--Also called niacinamide. While the nicotinamide/niacinamide forms of vitamin B3 can be used to treat B3 deficiency ("pellagra"), they do not reproduce the lipid and lipoprotein effects of niacin. For our purposes, they are useless.

Niacin-containing heart-healthy supplements--These are the multi-supplements that contain a little of everything that might be beneficial for the heart, but none at a dose that provides genuine benefit. Don't throw your money away.


There's also a prescription niacin, Niaspan, that costs 20-fold more than the best over-the-counter preparation, Sloniacin. Niaspan has yielded hundreds of millions of dollars for the pharmaceutical industry. Your money, in my view, is far better spent on Sloniacin (around $12-14 per bottle of 100 tablets of 500 mg).

For more on niacin, here's an article I wrote for the Life Extension Magazine people a while back: Using Niacin to Improve Cardiovascular Health.

Deja vu all over again?

HeartHawk brought a report and debate on The Heart.Org website to my attention:

Screening for risk factors or detecting disease? Debate divides the CV community. After landing on theheart.org, paste this onto your URL address:article/883239.do. (Full address: http://www.theheart.org/article/883239.do. I don't know why, but I couldn't go there directly.)

Some interesting comments:

Dr. Jay Cohn (University of Minnesota):

"They're saying that we can't identify disease very effectively so let's just stick with risk factors, which we know are very poorly predictive and nonspecific. It boggles my mind as to why they won't open up their minds to the importance of moving forward in finding better strategies to identify the disease that we are treating. It's very strange. They criticize these disease markers because they are not predictive of events, but they are looking at very short-term outcomes. We're interested in lifetime risk. We're screening people in their 40s who are concerned about morbid events in their 60s and 70s, and no trials are going to track them that long."

"You have to accept the pathophysiologic reality that heart attacks don't occur in the absence of coronary disease, and coronary disease doesn't occur in the absence of endothelial dysfunction and vascular disease, all of which now can be identified."

". . . Can we as a society and as a profession accept the idea that there is a link between the vascular abnormalities and the events? "And that that linkage is tight enough that it should allow us to accept slowing of progression of the vascular abnormalities as an adequate marker for slowing disease progression, without waiting for events to occur? As soon as you use the word surrogate, people jump up and say we have all these markers that we know don't work well—things like premature ventricular contractions [PVCs] on the electrocardiogram, LDL, HDL—but those are not the markers we're talking about. We're talking about structural and functional changes in the blood vessel and in the heart."



Wow. The idea may be starting to catch on.

As an interesting aside, Cohn et al use a 10-test panel to screen for vascular disease:

"Named for the center's benefactor, the Rasmussen score includes tests for large and small artery elasticity (compliance), resting blood pressure, blood-pressure response to moderate treadmill exercise, optic fundus photography, carotid intimal-media thickness (IMT), microalbuminuria, electrocardiography, left ventricular (LV) ultrasonography for LV volume and mass, and brain natriuretic peptide (BNP). Each test result is scored out of 10 for low, intermediate, or high risk, and the combined results yields a score that Cohn et al believe is more predictive than any of the existing standalone tests."


The counterarguments in this debate were provided by Dr. Philip Greenland (Northwestern University), who repeated his oft-used argument that, while he accepts that vascular disease can be identified, no one has proven that measuring it improves outcomes:

"We do have that evidence for risk-factor screening. Even though people criticize risk-factor assessment because it is not sensitive enough or not accurate enough, the interesting and curious thing is that we actually have evidence that if you go to the trouble of screening for risk factors and treating them, patients have better outcomes. We do not have that evidence for any of these other tests."


An interesting debate ensues that includes Track Your Plaque friend, Dr. William Blanchet, who characteristically argues persuasively in favor of broad screening for coronary disease with coronary calcium scoring:

"If we were doing our jobs in primary prevention, we would not need to look at improved intervention and secondary prevention to reduce coronary death."


Here's a shock: Dr. Melissa Shirley-Walton, the cardiologist who previously preached the "cath lab on every corner" argument seems to have undergone a change of heart:

"What if I walked up to a gentleman and said, "you are at risk for CAD, take a statin", to which he replies, "I'm afraid of those meds". BUT if he sees his calcium score........he is then convinced to be pro-active. What is so wrong with that? What is so wrong with allowing him to spend 250.00 US out of pocket in order to save the US 150,000.00 US later on?

No hard endpoints you say with intensive therapy for primary prevention? What about extrapolating from trials for secondary prevention like HATS? ARBITER2? And what exactly is the true definition of secondary prevention? Is it truly primary prevention if we already have intima thickness abnormalities, or fatty streaks? That would more likely fall under secondary prevention by today's new standards.

So, I'm all for any visual aid that will encourage compliance with life style change, necessary medical therapy and followup. If the patient is willing to spend 250.00$ to get a calcium score, so be it. Better yet, why not lower the price so everyone can have the option if they are motivated enough to seize an opportunity?"



I have to admit that I thought that Dr. Blanchet was wasting his time trying to persuade Shirley-Walton et al, but perhaps he is having an impact, though having hammered away at them for the last year or so.

These arguments, for me, eerily echo many previous debates I've heard. But I am encouraged by the more favorable treatment the notion of atherosclerosis screening is receiving. Just 5 years ago, all coronary calcium scoring would have received from the conventionalists is "more clinical studies are needed."

So perhaps the cardiology and medical worlds are inching slowly towards broad acceptance of screening for coronary and vascular disease.

BUT, screening is not sufficient. What do you do with the information?

Here is where the conventional-thinkers stop. The question that seems to occupy them: Perhaps we should screen people for hidden coronary and vascular atherosclerosis so we can better decide who needs a statin drug or a procedure.

I would pose a different challenge: We should screen people for hidden coronary and vascular atherosclerosis so we can better decide who needs to engage in an intensive program of disease reversal using natural means and as little medication and procedures as possible.

Well, perhaps in time.

Lead to Gold: The alchemy of transforming nutritional-supplement-to-medication

Here's a recipe to make hundreds of millions of dollars. Others have done it and you can do it, too!

1) Identify a nutritional supplement that works.

Find some agent deemed to fall within the broad allowances of the 1994 Dietary Supplement Health and Education Act . However, because this agent is already in the public domain and is essential non-patent-protectable, you may need to develop some patent protectable aspect of its production, application, or encapsulation. This patent-protected aspect may or may not provide genuine advantage, but that's not your concern. Your concern is protecting your investment and providing the appearance of exclusivity.


2) Identify a medical indication for your product.

Choose a disease or condition that is likely to yield unquestioned efficacy, e.g., omega-3 fatty acids to reduce high triglycerides in people with familial hypertriglyceridemia (triglycerides >500 mg/dl). While this will restrict your ability to make market claims, it will not restrain your ability to sell or allow use of your agent for "off-label" applications. In fact, there are methods to surreptitiously promote the use of your product for off-label use, such as hiring experts to discuss the science behind your product with doctors who can prescribe your product. Ideally, your product's primary indication will provide a substantial market on its own to justify your investment. However, the eventual off-label sales can be substantial, even outstripping the sales generated through your primary indication.


3) Obtain at least $230 million to pay for the clinical trials required to obtain FDA approval.

You will also have to raise the capital to build the business to manufacture, distribute, and sell your product.


4) After FDA approval is obtained, your business is up and running, and distribution begins, start bashing the non-FDA-approved nutritional products that stand to compete in your market.

You could point out that only your product has actually passed through the rigorous FDA process. You could make claims regarding purity, potency, "approved by your doctor," etc., whether or not there is any truth behind the claim.


5) Buy that second vacation home in Aspen and the corporate jet you've been dreaming about! After all the risks you've taken, you deserve it!


That's it, plain and simple. It is a tried-and-true formula that has been applied many times.

It is a formula like this that brought Lovaza-brand omega-3 fatty acids to market, Niaspan brand of niacin, ergocalciferol form of vitamin D, Folbee (prescription combination B vitamins), with a slightly different spin for Synthroid (since the Armour Thyroid it is meant to replace is not a nutritional supplement, but a low-cost, generic thyroid replacement).

Whatever you do, don't EVER run a head-to-head comparative trial of your agent versus the nutritional supplement competition. For instance, NEVER compare Lovaza to supplemental fish oil capsules, matched milligram-for-milligram for EPA and DHA content. NEVER compare Niaspan to over-the-counter Sloniacin. NEVER compare Armour Thyroid to Synthroid. You never know what you might find. (Psssssttt! They might be equivalent!)

The formula is not a foolproof road paved with riches, however. There have been market failures, as well. Folbee, for instance, is hardly a household name. So there's risk involved, no question about it. But, should it all work out, the payoff can be big, VERY big, as it has been for Niaspan and Lovaza.

So, start thinking about how you might follow this formula for:

1) Cholecalciferol (vitamin D3)--e.g., for osteopenia, low HDL, or high c-reactive protein
2) Vitamin K2--also for osteopenia
3) Magnesium--for suppression of ventricular arrhythmias (especially Torsade de Pointes)
4) Iodine--for goiter and iodine deficiency
5) Vitamin C--for uric acid reduction

Who said you can't turn lead into gold?

Another interview with Livin' La Vida Low Carb's Jimmy Moore

I recently provided another interview for Livin' La Vida Low Carb's Jimmy Moore.

You may remember Jimmy as the irrepressible host of the Livin' La Vida Low Carb Show who lost around 200 lbs, dropping from 410 to 230 lbs on a low-carbohydrate diet.

In this hour-long interview, we discussed some of the dietary strategies that we use in the Track Your Plaque program.

Jimmy's website is definitely worth exploring. It's loaded with great interviews, including with Good Calories, Bad Calories author, Gary Taubes.

"Millions of needless deaths"

"Millions of needless deaths" is the title of an editorial by Life Extension Magazine's Bill Faloon.

". . . If vitamin D’s only benefit was to reduce coronary heart attack rates by 142%, the net savings (after deducting the cost of the vitamin D) if every American supplemented properly would be around $84 billion each year. That’s enough to put a major dent in the health care cost crisis that is forecast to bankrupt Medicare and many private insurance plans."

Although I don't agree with all the over-the-top commentary that issues from Mr. Faloon or Life Extension (although I sit on their Medical Advisory Board), I agree with virtually all of the issues he raises with vitamin D.

Despite the enormously compelling observations of vitamin D potential effects in populations, the medical community's reluctance comes from the lack of treatment data. In other words, what we lack are long-term data on vitamin D supplementation vs. placebo on rate of heart attack, vitamin D vs. placebo on risk of colon cancer, etc.

The data that exists connecting vitamin D levels with cardiovascular risk originate from three population observations:

1) The NHANES data in 16,000 participants showed 20% increased risk of cardiovascular events in those with vitamin D levels <20>20 ng/ml after factoring in all standard risk factors.

Another NHANES analysis showed the high prevalence of vitamin D deficiency in those with cardiovascular disease.

2) A German study of 2500 participants that showed showed the lowest quartile of vitamin D levels (<13.3>28.4 ng/ml.

3) The Health Professionals' Follow-Up Study of 18,000 males showed a 2.4-fold increase in cardiovascular events in those with vitamin D levels <15>30 ng/ml.

While we lack treatment data (vitamin D vs. placebo) in a large population, we do have data that Suzie Rockway, Mary Kwasny (both from Rush University, Chicago) and I generated on the effect of vitamin D as a part of a broader treatment program on coronary calcium scores:

Effect of a Combined Therapeutic Approach of Intensive Lipid Management, Omega-3 Fatty Acid Supplementation, and Increased Serum 25 (OH) Vitamin D on Coronary Calcium Scores in Asymptomatic Adults.
Davis W, Rockway S, Kwasny M. Amer J Ther 2008 (Dec 15).

The impact of intensive lipid management, omega-3 fatty acid, and vitamin D3 supplementation on atherosclerotic plaque was assessed through serial computed tomography coronary calcium scoring (CCS). Low-density lipoprotein cholesterol reduction with statin therapy has not been shown to reduce or slow progression of serial CCS in several recent studies, casting doubt on the usefulness of this approach for tracking atherosclerotic progression. In an open-label study, 45 male and female subjects with CCS of >/= 50 without symptoms of heart disease were treated with statin therapy, niacin, and omega-3 fatty acid supplementation to achieve low-density lipoprotein cholesterol and triglycerides /=60 mg/dL; and vitamin D3 supplementation to achieve serum levels of >/=50 ng/mL 25(OH) vitamin D, in addition to diet advice. Lipid profiles of subjects were significantly changed as follows: total cholesterol -24%, low-density lipoprotein -41%; triglycerides -42%, high-density lipoprotein +19%, and mean serum 25(OH) vitamin D levels +83%. After a mean of 18 months, 20 subjects experienced decrease in CCS with mean change of -14.5% (range 0% to -64%); 22 subjects experienced no change or slow annual rate of CCS increase of +12% (range 1%-29%). Only 3 subjects experienced annual CCS progression exceeding 29% (44%-71%). Despite wide variation in response, substantial reduction of CCS was achieved in 44% of subjects and slowed plaque growth in 49% of the subjects applying a broad treatment program.


I also summed up the data as of early 2008 in a Life Extension article:

Vitamin D's Crucial Role in Cardiovascular Protection


I do agree with Mr. Faloon: It's time to take the vitamin D issue very seriously. Personally, I think it is foolhardy to not correct vitamin D deficiency, even in the absence of long-term treatment data.

Should we subject people living in tropical climates with vitamin D blood levels of 90 ng/ml to long-term observation? Though that has not yet been done, it has been done--in effect--through observations on the prevalence of diabetes, heart disease, and various cancers by latitude: the farther away from the equator, the greater the prevalence of these diseases.

That's more than good enough for me.

Thiazide diuretics: Treatment of choice for high blood pressure?

Thiazide diuretics are a popular first-line treatment for hypertension among the primary care set.

This practice became especially well-established with the 2002 publication of the ALLHAT Study (Major Outcomes in High-Risk Hypertensive Patients Randomized to Angiotensin-Converting Enzyme Inhibitor or Calcium Channel Blocker vs Diuretic:The Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT)).

ALLHAT showed that an inexpensive diuretic like chlorthalidone (a weak diuretic in the thiazide class, similar to hydrochlorothiazide) as first-line treatment for hypertension achieved equivalent reductions in cardiovascular events (cardiovasular death and heart attack) as non-thiazide antihypertensives, lisinopril (an ACE inhibitor) and amlodipine (a calcium channel blocker, better known as Norvasc).

After 7 years of treatment, there was 14% death or heart attack among all three groups--no difference.

This was interpreted to mean that inexpensive thiazide diuretics like chlorthalidone offer as much benefit as other blood pressure medications at reduced cost.

On the surface, that's great. Anything that detracts from the ubiquitous pharmaceutical industry propaganda of bigger, better, more expensive drugs to replace old, inexpensive, generic drugs is fine by me.

But you knew there'd be more to this issue! If we accept that thiazides are equivalent to other single-drug treatments for high blood pressure, what do we do with the following issues:

--Thiazides deplete body potassium-This effect can be profound. In fact, built into the ALLHAT mortality rate is an expected death rate from potassium depletion. When potassium in the body and blood go low, the heart becomes electrically unstable and dangerous rhythms develop.

--Thiazides deplete magnesium--Similar in implication to the potassium loss, magnesium loss also creates electrical instability in the heart, not to mention exaggeration of insulin resistance, rise in triglycerides, reduction in HDL.

--Thiazides reduce HDL cholesterol

--Thiazides increase triglycerides

--Thiazides increase small LDL particles--You know, the number one cause for heart disease in the U.S.

--Thiazides increase uric acid--Uric acid is increasingly looking like a coronary risk factor: The higher the uric acid blood level, the greater the risk for heart attack. Thiazides have long been known to increase uric acid, occasionally sufficient to trigger attacks of gout (uric acid crystals that precipitate in joints, like rock candy). (Fully detailed Special Report on uric acid coming this week on the Track Your Plaque website.)

What about the advice we commonly give people to hydrate themselves generously? Yet we give them diuretics? Which is it: More hydration or less hydration? You can't have both.

Do thiazides exert an apparent cardiovascular risk reduction in a society due to its flagrant sodium obsession?

Thus, there are a number of inconsistencies in the thinking surrounding thiazides. In my experience, I have seen more harm done than good using these agents. While I cannot fully reconcile the reported benefit seen in ALLHAT with what I see in real life, all too often I see people having to take another drug to make up for a side-effect of a thiazide diuretic (e.g., high-dose prescription potassium to replace lost potassium, allopurinol to reduce uric acid, etc.). I have seen many people get hospitalized, even suffer near-fatal or fatal events from extremely low potassium or magnesium levels.

My personal view: ALLHAT or no, avoid thiazide diuretics like the plague. Sure, it might save money on a population basis, but I suspect that the ALLHAT data are deeply misleading.

What's better than a thiazide, calcium blocker, or ACE inhibitor? How about vitamin D restoration, thyroid normalization, wheat elimination?

"High-dose" Vitamin D

I stumbled on one of the growing number of local media stories on the power of vitamin D.

In one story, a purported "expert" was talking about the benefits of "high-dose" vitamin D, meaning up to 1000, even 2000 units per day.

I regard this as high-dose---for an infant.

Judging by my experiences, now numbering well over 1000 patients over three years time, I'd regard this dose range not as "high dose," nor moderate dose, perhaps not even low dose. I'd regard it as barely adequate.

Though needs vary widely, the majority of men require 6000 units per day, women 5000 units per day. Only then do most men and women achieve what I'd define as desirable: 60-70 ng/ml 25-hydroxy vitamin D blood level.

I base this target level by extrapolating from several simple observations:

--In epidemiologic studies, a blood level of 52 ng/ml seems to be an eerily consistent value: >52 ng/ml and cancer of the colon, breast, and prostate become far less common; <52 ng/ml and cancers are far more likely. I don't know about you, but I'd like to have a little larger margin of safety than just achieving 52.1 ng/ml.

--Young people (not older people >40 years old, who have lost most of the capacity to activate vitamin D in the skin) who obtain several days to weeks of tropical sun typically have 25-hydroxy vitamin D blood levels of 80-100 ng/ml without adverse effect.

More recently, having achieved this target blood level in many people, I can tell you confidently that achieving this blood level of vitamin D achieves:

--Virtual elimination of "winter blues" and seasonal affective disorder in the great majority
--Dramatic increases in HDL cholesterol (though full effect can require a year to develop)
--Reduction in triglycerides
--Modest reduction in blood pressure
--Dramatic reduction in c-reactive protein (far greater than achieved with Crestor, JUPITER trial or no)
--Increased bone density (improved osteoporosis/osteopenia)
--Halting or reversal of aortic valve disease

(I don't see enough cancer in my cardiology practice to gauge whether or not there has been an impact on cancer incidence.)

My colleagues who have bothered to participate in the vitamin D conversation have issued warnings about not going "overboard" with vitamin D, generally meaning a level of >30 ng/ml.

I know of no rational basis for these cautions. If hypercalcemia (increased blood calcium) is the concern, then calcium levels can be monitored. I can reassure them that calcium levels virtually never go up in people (without rare diseases like sarcoid or hyperparathyroidism). Then why any hesitation in recreating blood levels that are enjoyed by tropical inhabitants exposed to plentiful sun that achieve these extraordinary health effects?

For the present, I have applied the target level of 60-70 ng/ml without apparent ill-effect. In fact, I have witnessed nothing but hugely positive effects.

Vitamin D Home Test

The ever-resourceful Dr. John Cannell of the Vitamin D Council has announced the availability of an at-home, self-ordered vitamin D test kit for $65. The Vitamin D Council newsletter is reprinted below.

(However, please note that, as wonderful as the advice Dr. Cannell provides, I don't agree on several small points, such as the lack of need for vitamin D if you use a tanning bed or obtain "sufficient" sun; I have seen many people with dark tans, virtually all over 40 years old, who are still severely deficient. I attribute this to the lost capacity for vitamin D activation as we age.)

I have not used this service. Should anyone choose to try it, please let us know how it goes.



The Vitamin D Newsletter
December 28, 2008

The Vitamin D Council is happy to announce that we have partnered with ZRT Laboratory to provide an inexpensive, $65.00, in-home, accurate, vitamin D [25(OH)D] test. The usual cost for this test is between $100.00 and $200.00.

If you read this newsletter, you know about our interest in accurate vitamin D testing. In the next few weeks, you may read about the Vitamin D Council's quest for accurate vitamin D blood tests in the national media. Before we partnered with ZRT, we verified, repeatedly, that ZRT provides accurate and reliable vitamin D tests and that their method corresponds very well to the gold standard of vitamin D blood tests, the DiaSorin RIA.

Our ZRT service is not just inexpensive, it means no more worrying about your doctor ordering the right test or interpreting it correctly. You buy the test kit on the internet or by phone, a few days later the kit comes in the mail, you or a nurse friend do a finger stick, collect a few drops of blood, and send the blotter paper back to ZRT in the postage paid envelope provided with the kit. A week later you get results back in the mail and know accurate 25-hydroxy-vitamin D levels of you and your family.

For every test you order, ZRT will donate $10.00 to the Vitamin D Council. Please read the new page hyperlinked below on our website as it both explains the procedure and how to order the test.

http://www.vitamindcouncil.org/health/deficiency/am-i-vitamin-d-deficient.shtml

Executive summary: keep your family's 25-hydroxy-vitamin D blood test above 50 ng/ml, year around. Most adults need at least 5,000 IU per day, especially this time of year. Most children need at least 1,000 IU per day per every 25 pounds of body weight. Bio Tech Pharmacal provides high quality and inexpensive vitamin D. Currently Bio Tech Pharmacal is providing vitamin D for numerous scientific studies. To see their prices and for ordering, click the hyperlink below.

Where do Track Your Plaque membership revenues go?

People pay about $90 per year to become Members on the Track Your Plaque website. This provide access to our in-depth Special Reports, guides, webinars, and our proprietary software data tracking tools. Members can also participate in online discussions, such as those in the Track Your Plaque Forum and chats.

Why is there a charge for membership in the program and where does the money go?

Money raised from membership fees goes towards:

1) The costs of doing business, e.g., server fees, software purchases, legal fees. Hosting webinars, for instance, costs us about $99 per month for the GoToWebinar software service.

2) Software development--Our most recent round of software data tracking tools, for instance, cost us nearly $30,000. That may not be a lot from big business standards, but it is onerous enough that obtaining membership dues really helps.

3) Graphics development--A website without graphics would be awfully dull, regardless of the quality of the textual content. Some of the newest tools on the Track Your Plaque website require photography and graphics work, which can add up very quickly.


Where membership fees do NOT go:

1) In our pockets--In fact, except for the various contractors who are paid for their services (e.g., software developers), NOBODY on the Track Your Plaque staff are paid: not me, nor any of the behind-the-scenes staff. Some of the staff overlap with my office staff, but they are paid purely out of the office revenues, not out of Track Your Plaque membership dues.

2) Towards overhead costs beyond those listed above--For example, membership fees do not pay for office lease, utilities, phones, etc.


We rely on membership fees because we have chosen to remain as free of commercial bias as possible. We host no advertising, we have no behind-the-scenes corporate or institutional agendas, we show no favoritism to any business or commercial operation. We believe this permits editorial freedom that few other health websites can enjoy. (In fact, I know of no other that is so free of commercial bias, outside of small blogs or narrow-interest websites.)

If you want to see what damage commercial bias can create, just go to a health website like WebMD. I challenge you to find information that is not flagrantly biased by commercial influence, namely that of the drug industry. (According to the WebMD SEC filings, in fact, the great majority--approximately 80%--of their $331 million revenues (2007) were derived directly or indirectly from the drug industry.) This commercial bias reaches into all of WebMD's related businesses, including MedicineNet.com, RxList.com, Medscape.com, and several others.

Preventing heart disease is not a money maker, sad to say. It is, from the perspective of conventional heart care, a big money loser. Undergo a heart catheterization, hospitalization, stent or bypass for anywhere from $14,000 to well over $100,000---or pay $90 for in-depth health information that dramatically reduces the potential need for the hospital and its procedures, minimizes need for prescription medication (statins alone, of course, are a $27 billion annual revenue phenomenon), and achieves all this by maximizing nutrition, self-purchased nutritional supplements, and inexpensive heart scans. Nobody is going to make a bundle off of this approach.

So that is why we charge a membership fee. I often get a laugh from some of the comments of people on this blog or even in my office who believe that we are rolling in money from the website from membership dues. The opposite is true: We don't pay ourselves. Virtually every penny is reinvested back into the website to better serve the Members.

Wheat-free and still fat

Readers of The Heart Scan Blog know that I preach a diet that contains foods with low glycemic index to control weight, raise HDL, and reduce triglycerides, blood sugar, and small LDL.

A crucial aspect of a low glycemic index approach is to sharply reduce, preferably eliminate, wheat products.

I pick on wheat specifically because it has come to dominate the American diet. Look at the shelves in the supermarket: aisle after aisle of processed wheat products. The bread shelves alone in some of the grocery stores in my neighborhood are 40 feet long, six shelves high. There's also breakfast cereals, granola products, cookies, cakes, baking products, pretzels, crackers, pasta, and on and on.

Wheat products like these are tasty and they're addicting--literally. Test animals given processed wheat will eat more and gain more weight. Wheat fails to trigger satiety. So laboratory mice--and you and I--eat and eat, because eating wheat stimulates appetite, creates a hunger for more wheat, and a vicious cycle ensues. Eliminating wheat, on the other hand, results in dramatic drop in appetite, substantial weight loss, followed by correction of the metabolic disruptions it created.


A quick Google search for "gluten-free" turns up a startling array of wheat-free, gluten-free, yet high glycemic index products. The breakfast cereal pictured, for instance, can do as much damage as most wheat containing products--though it won't cause gluten enteropathy (also known as "celiac disease").




The product shown contains:

Brown rice flakes, rice bran, evaporated cane juice, brown rice syrup, raisins, cinnamon, gum arabic, vanilla, molasses, ground flaxseed, rosemary extract.

A 1/2-cup serving contains:
Total Carbohydrate 31g
Dietary Fiber 5g
Sugars 8g


And I'll bet that most people eat a lot more than a half-cup serving.

But you and I are not laboratory mice. If deprived of wheat, many people will then seek out processed rice products (rice cakes, Rice Krispies), processed cornstarch or cornmeal products (tacos, cornbread, many processed foods using these products for texture or thickness), or other products labeled "gluten-free."

Going wheat-free for our purposes is not about avoiding the gluten in wheat. It is about seizing control of appetite, eliminating a food that disrupts insulin responses, reduces HDL, raises triglycerides, and creates small LDL particles. But this applies to processed corn, rice, and other high glycemic index foods, as well.

So, occasionally, someone will declare, "I've eliminated wheat! Now I only eat rice, corn, and I've discovered all the gluten-free alternatives!"

Unfortunately, they've traded one evil for another. So it's not just about wheat. It's really about reducing or minimizing foods that mess up metabolic responses and lead to coronary plaque growth. Wheat is the biggest culprit and so I focus on it. However, you could easily transfer far less popular rice and corn products into center stage and allow them to wreak all the health damage of wheat.

Going wheat-free for our atherosclerotic plaque-control purposes is not the same as going gluten-free. So be careful of the distinction.

Heart disease is reversible

In a previous post, Take this survey: I double-dare you, I posed a challenge:

Ask your doctor: Is heart disease reversible? Their answer:

1) No. Heart disease is definitely not reversible.

2) Yes, in rare instances, like lightning striking twice.

3) Yes, of course it is! Let's talk about how to do it!

I predicted that few readers of this blog would respond. I also predicted that the few who did would respond with the first answer, Heart disease is definitely not reversible. After all, in nearly all medical practices, the only parameters routinely followed to track risk for heart disease are LDL cholesterol and blood pressure. A measure of the disease itself (i.e., coronary atherosclerotic plaque) is not followed. So how can your doctor actually tell whether heart disease is reversed or not? When I engage in this conversation with colleagues, it goes no farther than rolled eyes or a snort. In my experience, talking about reversal of heart disease is a wasted effort.

To my great surprise, this simple survey received a total of 177 responses. Even more surprising, 122 (69%) of respondents chose number 3, claiming that their doctor said that heart disease is reversible.

Overall results:

1--31 responses (17.5%)

2--24 responses (13.5%)

3--122 responses (69%)


Now wait a minute: Where is the disconnect? Why are doctors saying that heart disease is reversible, yet not following this concept in practice? Contrary to the survey results, I have yet to meet a patient who said their doctor was trying to reverse their heart disease. Of course, this may be a skewed population, but I find it hard to believe that the prevailing view is that heart disease is reversible.

Anyway, this simple survey cannot settle the why or how, nor can it suggest just how prevalent this opinion is.

I am encouraged by these results. If true, it means that the message that heart disease is a reversible process is spreading. It may be make-believe heart disease reversal as preached by Dr. Dean Ornish or claimed by statin drug manufacturers. It may be the hocus-pocus of practices like chelation, or scams like nattokinase. But perhaps the seed of this notion has been planted in the minds of the medical community.

I'd be interested in hearing from the respondents who reported that their doctor said heart disease is reversible. How exactly are they going about achieving reversal?

Looking for health in all the wrong places

The American public now has unprecedented freedom to explore new directions in health.

Never before have we had the enormous resources now available to add to our health experience: nutritional supplements, endless books on health and diet, the internet, online discussion groups, insurance products to permit spending on self-directed health services like medical savings accounts and flex-spending. The Track Your Plaque program is just one facet of this emerging and exciting area of self-empowerment in health. Compare what you can achieve with such a program with the situation of just 25 years ago, when the most you might get to reduce your risk for heart disease was to take the (largely ineffective) drug cholestyramine, probucol, and a low-cholesterol, low-fat diet.

Unfortunately, it also means that people have unrestrained potential to be tripped up, to be misled down some dead end of health that fails to accomplish desired goals, maybe even dangerous. The more freedom we have, the greater the choices, the more room we have to screw up.

Among the unproductive strategies I've witnessed recently:

--Nattokinase--The staying power of this scam continues to shock me. There is no rational basis for its use. A woman today declared that she would like to stop the warfarin that she was taking to prevent stroke from atrial fibrillation by taking nattokinase. This would be a mistake that could cost her a major and disabling, even fatal, stroke. Though warfarin is far from perfect, it at least achieves its goal of reducing stroke risk. Nattokinase does not. Nattokinase does nothing but make money for the people who sell it.

--Poly-nutritional supplements. You've heard of polypharmacy, the phenomenon of taking numerous medications with overlapping effects and side-effects, usually because of multiple doctors, each prescribing drugs without knowledge or interest in what colleagues are prescribing. I'm seeing the same phenomenon with supplements: 20,30, or more supplements per day, all in the hopes of heightening health. A focused few supplements is, in my view, superior to a shotgun approach of trying to improve health by taking hawthorne, silymarin, chrysin, calcium, Chinese herbs, and 25 other supplements.

--Chelation--Based on the notion that heavy metal toxicity causes heart disease; removal of heavy metals cures it. I've read some of the books on chelation, in addition to the slim scientific data, to decide whether there was anything to it. In my view, it is a complete and utter scam. It does make money for its practitioners, however. That's not to say that heavy-metal chelation doesn't have a role in health--it does. But it serves no purpose in coronary disease prevention and control.

--Colonic purges--Achieved by a number of routes, some oral, others via enema. Promotions for purging are often accompanied by a pile of scum that apparently lined somebody's intestinal tract. Purges purportedly, well, purge it from the intestine. This is also plain nonsense. There is no such toxic scum lining anybody's intestinal tract. However, if calorie restriction or a fast results inadvertently from the effort, perhaps some good comes from it.

--Statin drug alternatives--The unprecedented $27 billion dollar a year success of the statin drug industry, accompanied by the enormous marketing push by their manufacturers, has spawned an entire industry of statin alternatives. They range from red yeast rice, to guggulipid, to various concoctions of sterol esters, Chinese herbs, chitosan, and a variety of others. Some actually do reduce cholesterol a few points. Preparations like red yeast rice even pose a side-effect profile not too different from the prescription statin agents. Unfortunately, even among those agents that work, the effects tend to be small to trivial. While I am no lover of statin drugs nor the statin drug industry, I find these preparations to be anemic imitators. You'd be better off with raw nuts and ground flaxseed than wasting your money on these cheap imitations.

--Worries about liver toxicity--A day doesn't go by that I don't have at least several questions about suffering toxic liver effects from niacin, vitamin D, statin drugs, etc. I have treated thousands of patients for heart disease in its various stages and forms and have used many different strategies. How many times have I seen serious liver toxicity? A handful of times and usually from either mis-use of the agent or drug, or in a person with several other coexisting diseases. (Other serious health conditions, like kidney failure, raise the toxicity of drugs and supplements.) Liver toxicity in the vast majority of otherwise healthy people is close to being a non-concern.


Readers of The Heart Scan Blog and of the Track Your Plaque website know that I celebrate expansion of knowledge and information access to the public. However, I am concerned that the flip side of this growing self-empowerment is expanding potential for mistakes. It reminds me of an attorney friend, who, when diagnosed with prostate cancer, explored all manner of alternative treatments, from laetrile to heavy metal chelation to high-dose lycopene tablets. At the initial stage of diagnosis, his cancer was readily treatable. He now has widely metastatic cancer.

Maintain an open mind, but think before you commit to some crazed claim of cure, some "secret" to health, somebody's brazen but concealed attempt at steering profits in their direction.

With freedom comes responsibility. Otherwise, you might be looking for love . . .oops, I mean health . . . in all the wrong places.

Track Your Plaque APB

I'm posting this intriguing comment from the Track Your Plaque Member Forum because I would like to speak to the Member who posted it.

The Member said:

I tested at 965 last year, and while I have followed the TYP diet and nutraceutical recommendations, I was totally unprepared for my first repeat scan (at the same lab/machine) on January 29, 2008. My result was 4.0, and at first I assumed the rating scale had been changed.

I then noted that 3 of the big four arteries received scores of 0, which means the same in any scale, and that four nodules had disappeared from the scan field.



Wow!!

If this is true, it would represent the biggest success in the Track Your Plaque program--ever! It would be an incredible story to tell, to convince the public and medical community that it is indeed possible, and a cause for popping a bottle of champagne! It would also represent what I would regard as essentially a cure for coronary atherosclerosis, a virtual elimination.

While we have plenty of success in stopping the progression or reducing heart scan scores, we do not have 100% success. I wish we did. The Track Your Plaque program is, to some degree, a work in progress. We learn from experiences, continually adjust to obtain the results we desire. Even as it stands today, the Track Your Plaque program is superior to any program of heart disease prevention known--by a long stretch. But it's not infallible, it's not foolproof.

That's all the more reason I would like to communicate with the Track Your Plaque Member who posted this comment. I would also like permission to view the heart scans themselves. (I can't obtain them nor view them without the individual's permission.) While we often have difficulty judging reversal just by looking at heart scans, presumed reversal to this profound degree should be obvious, even to the naked eye.

I would like to know--in detail--precisely what steps were taken and whether there was anything unique about this person's medical history or in the program they followed. This is all in an effort to learn and help others do the same.

If you are the Member who posted this comment, I would like to hear more. Please post your further thoughts on the Track Your Plaque Member Forum, or privately through our Contact page . Or e-mail us at contact@cureality.com.

Vitamin D toxicity

It is the craziest thing.

The notion of vitamin D being easily and readily toxic has grabbed hold of many people, including my colleagues who were taught that vitamin D was toxic in medical school based on the skimpiest (and often misinterpreted) observations in a handful of unusual cases.

In my practice and in the Track Your Plaque program, we routinely use doses of 2000-10,000 units per day, occasionally more. We are guided by blood levels of 25(OH) vitamin D3. I have personally never witnessed vitamin D toxicity.

Here's an interesting graph from Dr. Reinhold Vieth. Those of you familiar with the vitamin D argument know that Dr. Vieth is among the few genuine gurus in the vitamin D world.



















From Vieth R. Vitamin D supplementation, 25-hydroxyvitamin D concentrations, and safety. Am J Clin Nutr 1999;69:842-856. (Full text is available without charge.)

In the graph, the X's represent toxicity; circles fall within the non-toxic range. (Toxicity is generally defined as a level sufficient to raise blood calcium levels, "hypercalcemia.") Note that the 25(OH) vitamin D3 levels are given in nmol/L; to convert to ng/ml units that are customary in the U.S., divide the nmol/L value by a factor of 2.5.

You will notice that toxicity is virtually unheard of until the dose exceeds 10,000 units per day. Beyond 10,000 units per day, the curve heads upward sharply and toxicity does become a possibility, though not an absolute (since there are circles above 10,000 units).

You may also notice that the curve is relatively flat from vitamin D doses between 200 units and 10,000 units (log scale on x axis; arithmetic scale on y), the range of most common doses for vitamin D supplementation.

Another perspective on vitamin D blood levels is to examine the blood levels of people who are young and obtain plentiful sun exposure. Lifeguards, for instance, have blood levels of 84 ng/ml (210 nmol/L) without ill-effect. (Sun exposure cannot generate vitamin D toxicity, because of a feedback safety mechanism in skin.) While this may not represent an ideal level since they represent an extreme, it does provide reassurance that such levels are non-toxic. I also point out these levels occur in the youthful since most people lose 75% or more of vitamin D activating capacity in the skin by their 70s. Most of us over 40 are kidding ourselves if we think that a suntan provides sufficient vitamin D.

Keep in mind that it is not necessarily the dose of vitamin D that is toxic, but the blood level it generates. I take 10,000 units of vitamin D as a gelcap per day to maintain my blood level between 50-60 ng/ml (125-150 nmol/L). This strategy helps me keep my HDL in the 70-80 mg/dl range, my blood sugar around 90 mg/dl, my blood pressure <120/80, and I no longer experience colds nor winter "blues."

Turning plaque into profit

For reasons unknown to me, I received a solicitation to invest in a company called Prescient Medical, with a slogan that caught my eye:


Detect and treat heart attacks before they occur.


The glossy brochure details their technology development strategy:

Predict(TM) Optical Catheter System--A catheter introduced into the coronary artery during a catheterization procedure to determine whether a specific plaque or vessel area is "vulnerable," i.e., prone to rupture in future.

Protect(TM) Luminal Shield--A stent-like metal device deployed into the coronary artery at the region of vulnerable plaque to prevent future plaque rupture.

The company anticipates FDA approval for their systems by 2009 and sales to begin by 2010. They predict sales of $7 billion.

Let's stop and think about this for a moment. It seems to me that, rather than pursuing the market of another stent for a "severe blockage," this company is going after the untapped procedural market of vulnerable plaque. In other words, their technology (an optical sensor technology that emits and analyzes light wavelengths to map specific plaque characteristics) identifies plaque that may rupture in months or years, followed by implantation of stent(s) that presumably prevent plaque rupture.

Thus, conceivably, many 20%, 30%, 40% etc. "blockages", atherosclerotic plaques that do not block flow and thereby pose no need for a conventional stent, will end up with this new type of stent. One patient could therefore receive multiple "Luminal Shields" in a single procedure.

When would these devices be employed? One pathway I could conceive of that my colleagues will be sure to exploit is 1) identify plaque by CT angiography, then 2) bring patient to the catheterization laboratory and perform this procedure for whatever hot, vulnerable plaques are identified. In other words, symptoms are no longer necessary. Reduced blood flow is no longer necessary. An abnormal stress test is no longer necessary. All that is required is that you have plaque. If the plaque is then determined to be vulnerable, then it is stented.

What bothers me about all this is the emerging effort to exploit this untapped market--a big one--of early heart disease as identified by coronary atherosclerotic plaque. As heart scans have demonstrated, there is an enormous amount of hidden heart disease in this world. This company has discovered a way to turn plaque into a profit opportunity, much as the statin drug industry found a way to "turn cholesterol into money."

The conventional stent market has plateaued and now has been, to some degree, battered by the drug-coated stent argument. Prescient has found a new and significant market for procedures and stents.

Is this really necessary? Why does plaque have to become a procedural disease? Doesn't it make more sense that, if vulnerable plaque is identified, that clinical trials are then designed to develop treatment strategies that modify vulnerable characteristics? Shockingly, this has not been done to any significant extent. Instead, the easiest path to a profit opportunity is to implant a "Luminal Shield."

You and I are able to inactivate, disempower, and essentially shut down plaque, while others are working furiously to convert it into a procedural profit opportunity. I personally find this so distasteful that I would sooner endorse a high-dose statin strategy than this approach.

You can view a video of my colleague, Dr. Martin Leon, on the Prescient Medical website, (or click here to go directly to the video), talking about how this technology will "change the treatment paradigm of the interventionalist from reactive to proactive." Scary stuff. Dr. Leon has made millions of dollars (probably more like tens of millions of dollars) from his support of technology companies for the interventional coronary device market.

My hope is that word of the sorts of techniques we use in the Track Your Plaque program disseminate before this sort of luminal coating idiocy gets off the ground.

(In actuality, a different version of this approach has been available for years using intravascular ultrasound (IVUS), another procedure that involves threading a catheter down each coronary artery during a catheterization procedure. IVUS can also cross-sectionally map a plaque's anatomy and identify "vulnerable" features, like a thin cap overlying a collection of semi-liquid fat ("lipid pool"). There has been some discussion of using this approach to identify vulnerable plaque followed by stent implantation, but it has never gotten off the ground and has certainly not found validation in any clinical study. By the way, any stent prevents plaque rupture, since by their very nature, the plaque contents are compressed, modified, and excluded to the exterior of the stent. Plaque rupture within a stent is very rare in its few millimeters of length. It may therefore not require some new technology to prevent plaque rupture.)

Statin mono-failure

Evan's first heart scan score in November, 2006 yielded a high score for a 56-year old male: 542.

So he put up little fuss when his doctor prescribed simvastatin at a high dose.

Evan's LDL cholesterol before simvastatin: 158 mg/dl

Evan's LDL cholesterol on simvastatin: 72 mg/dl.

By conventional standards, Evan has had an excellent response. The rest of his lipid (cholesterol) panel was unrevealing: HDL 62 mg/dl, triglycerides 78 mg/dl. Evan doesn't smoke, has a normal blood pressure, and he is not diabetic. That should do it, right?

So his doctor thought. So Evan asked if another heart scan was in order. In December, 2007, after one year of simvastatin, his second heart scan score: 705--a 30% increase over one year.

Recall that, with no effort at prevention whatsoever, the natural progression of heart scan scores is a 30% per year increase. Did simvastatin do nothing?

This is quite typical of people who do nothing more than take a statin drug. While some people do slow plaque growth (we say "decelerate") modestly on a statin drug, Evan's experience is not unusual: plaque continues to grow despite high-dose statin drug and an apparently favorable cholesterol panel.

In fact, I can count the number of people who reduced their heart scan scores taking a statin drug alone on one finger.

Statins do not represent a cure for heart disease. They cannot be used as sole therapy to reduce risk for heart attack. In fact, given sufficient time, the majority of people who do nothing more than follow this standard line of treatment (along with the equally lame low-fat diet, etc.) will have done nothing more than postpone their heart attack. Elimination of risk? Nope.

This is among the reasons we developed the Track Your Plaque approach. While not foolproof, I know of no better approach to seize control over plaque growth.

Additional conversations on clinical studies which, as with Evan's experience, demonstrated how statin drugs fail to slow plaque growth can be found in previous Heart Scan Blog posts:

Don't be satisfied with "deceleration"

Triglyceride traps

Triglycerides are a potent trigger for coronary plaque growth.

Triglycerides in and of themselves probably do not cause plaque growth. Instead, triglycerides contribute to the formation of abnormal lipoproteins in the blood that, in turn, trigger coronary plaque, like VLDL, intermediate-density lipoprotein (IDL), and small LDL. Excess triglycerides also modify HDL structure and cause you to lose HDL in the urine.

I see plenty of people who begin with triglycerides of 200 mg/dl, 300, 700, even over 1000 mg/dl. It doesn't take long before you learn what works, what doesn't to reduce triglycerides. This is especially true in the Track Your Plaque approach, in which our target for triglycerides is 60 mg/dl or less.

Here's a list of things to consider if you are trying to gain control of your triglycerides:

--Fish oil--A mainstay of treatment. The omega-3 fatty acids from fish oil are the number one most potent treatment for high triglycerides.

--Reduction of high-glycemic index foods--Most notably wheat. Everybody knows that we shouldn't eat Snickers bars or bags of licorice. But many people eat plenty of wheat-containing breads, pastas, pretzels, crackers, breakfast cereals, etc., all in the name of increasing whole grains and fiber. In reality, they are causing triglycerides to skyrocket, dropping HDL, forming small LDL, increaaing blood sugar and blood pressure, and increasing obesity.

--Eliminating fructose and high-fructose corn syrup--This ubiquitous sweetener is now consumed in enormous quantities by the average American, nearly 80 lbs per year per person. You'll find it in soft drinks, ketchup, beer, breads, breakfast cereals, and many other processed foods. You'll find none in green peppers, cucumbers, and raw nuts. Fructose causes large rises in triglycerides, as well as diabetic patterns. Don't let "fat-free" claims fool you. Take a look at the ingredients in Kraft Fat-Free Caesar Italian salad dressing, for instance:

Kraft Fat-Free Caesar Italian

Ingredients:
Water, Vinegar, High Fructose Corn Syrup, Corn Syrup, Salt, Parmesan Cheese, Part-Skim Milk, Cheese Culture, Salt, Enzymes, Contains less than 2% of Garlic, Whey, Onion Juice, Autolyzed Yeast Extract, Phosphoric Acid, Worcestershire Sauce, Vinegar, Molasses, Corn Syrup, Water, Salt, Caramel Color, Dried Garlic, Sugar ,Spices, Tamarind, Natural Flavors, Hydrolyzed Soy Protein, Xanthan Gum, Potassium Sorbate and Calcium Disodium EDTA as Preservatives, Dried Garlic, Buttermilk, Spice, Dried Parsley, Caramel Color, Sodium Phosphate, Oleoresin Paprika.



--Alcohol--While a couple of drinks a day raises HDL, exerts anti-inflammatory effects, and reduces blood pressure, more than this begins to raise triglycerides. Although I've come across no formal studies on this question, my gut sense is that beer, in particular, raises triglycerides more than wine or other alcoholic beverages. Could it be the wheat source of beer? Or its high-fructose corn syrup? I don't know, but beer is the least desirable form of alcohol of the choices we have.


Following these simple steps, it is unusual in my experience that you cannot achieve a triglyceride level <60 mg/dl. Rarely do we need to add fibrate drugs or other prescription agents to reduce triglycerides.

High-dose fish oil for Lp(a)

Lipoprotein(a), or Lp(a), is a problem area in coronary plaque reversal.

While our current Track Your Plaque record holder for largest percentage reduction in heart scan score has Lp(a), it remains among the more troublesome lipoprotein patterns.

One unique treatment for Lp(a) is high-dose omega-3 fatty acids from fish oil. While the data are relatively meager, there is one solid study from Lp(a) expert, Dr. Santica Marcovina of the University of Washington, called "The Lugalawa Study."

In this unique set of observations, 1300 members of a Bantu tribe living in Tanzania were studied. What made this population unusual is the fact that two groups of Bantus lived under different circumstances. One group lived on Nyasa Lake (3rd largest lake in Africa and reputed to have the greatest number of species of fish of any lake in the world) and ate large quantities of freshwater fish providing up to 500 mg of omega-3s, EPA and DHA, per day. Another Bantu group lived away from the lake as farmers, eating a pure vegetarian diet without fish.

Nyasa Lake












This situation among genetically similar stock provided a unique learning opportunity, a chance to assess whether different diets influenced Lp(a) levels.

The results: The fish-eating Bantus had an average Lp(a) level of 14.0 mg/dl. The farming, non-fish eating Bantus had an average Lp(a) of 27.0--a 48% difference. Curiously, a comparison of the apo(a) component of Lp(a) between the groups also showed that the fisherman expressed fewer dangerous small apo(a) forms, despite equal potential to express both.

The Lugalawa Study opens the question of whether similar results can be obtained not by moving to Tanzania and fishing Nyasa Lake, but by mimicking their experience by supplementing high doses of omega-3 fatty acids.

It's an intriguing question. In the Track Your Plaque program, we have no specific experience with this strategy, but it is certainly worth exploring further.

Watch for two upcoming Special Reports on the Track Your Plaque website in which we will be detailing 1)unique strategies for Lp(a) reduction, and 2) the usefulness of high-dose fish oil for coronary plaque reversal.

Interesting enough for a Virtual Clinical Trial?

The many faces of LDL

Pam has an LDL cholesterol of 144 mg/dl.

To most people, this means that she has a mildly elevated LDL value. Many people would respond by cutting the saturated fat in their diet. Most physicians would concur and talk about prescribing a statin drug.

Let me tell you what an LDL cholesterol of 144 mg/dl means to me:

1) It could mean an LDL of all large particles (which is good) or an LDL of all small particles (which is very bad). Or, perhaps it's some combination of big and small. I can't tell which just by knowing that LDL is 144.

Small LDL responds to a diet reduced in processed carbohydrates and wheat flour; large LDL does not. Small LDL responds in an exagerrated way to niacin; large LDL does not. It makes a difference.

2) It could mean that, hidden within LDL, is lipoprotein(a), or Lp(a). Recall that Lp(a) is a high-risk genetic pattern that can provide the false appearance of high LDL cholesterol. If Pam were prescribed a statin drug, it would have little effect and little benefit. (See Red flags for Lipoprotein(a).)

Knowing that Pam has Lp(a) can point us in an entirely different direction than just LDL cholesterol. It might mean high-dose fish oil, a more serious approach to niacin, hormonal treatments like DHEA or testosterone. It might mean more attention to warning your children about the possibility that they, too, might share this genetic trait.

3) It could mean both small LDL and Lp(a) are present simultaneously, an especially dangerous combined pattern that is among the highest risks for heart disease known.

4) Because Pam's LDL of 144 mg/dl was not measured, but calculated, it means that it is subject to tremendous inaccuracy.

In my office, calculated LDL cholesterols can be inaccurate by 50 or 100 mg/dl--commonly. So Pam's LDL of 144 mg/dl could really be 70 mg/dl, or it could be 244 mg/dl. Once again, it's a big difference.


Just like The Three Faces of Eve, the 1957 film in which Joanne Woodward played the three wildly different sides of Eve's personality--the daytime Eve White, the fun-loving and daring Eve Black, and Jane--so can LDL assume several different faces, all with different personalities, different implications.

Accepting LDL cholesterol as LDL cholesterol is a fool's game. It is only a starting point, nothing more. Accepting a statin drug based on LDL is, likewise, a trap fraught with uncertainty, the potential for limited or ineffective results, the price being your heart and health.
