Apo E4 and sterols: Lethal combination?

Phytosterols, or just "sterols" to its friends and neighbors, are a group of cholesterol-like compounds that are abundant in the plant world. Lately, however, sterols have proliferated in the processed food supply, thanks to the observation that sterols reduce LDL cholesterol when ingested by humans.

This must mean that sterols are good for you.

Uh oh. Wait a minute: There is a rare disease called sitosterolemia in which there is unimpeded intestinal absorption of all sterols ingested through diet. They must have really low LDL cholesterols! Nope. They develop coronary disease--heart attacks, angina, etc.--in their late teens and 20s. In other words, if sterols gain access to your bloodstream, they are bad. Very bad.

Conventional thinking is that only a modest quantity of dietary sterols gain access to the bloodstream. But there are two potentially fatal flaws in this overly simplistic line of thinking:

1) What happens when you load up your diet with "heart healthy" sterols, such as those in "heart healthy" margarines, mayonnaise, and yogurt, effectively increasing sterol intake 10-fold?

2) What happens in people with the genetic pattern, apo E4, that is carried by 25% of the general population that permits much greater intestinal absorption of sterols?

My prediction: Despite the fact that sterols reduce LDL, they may, in certain genetically-susceptible people, such as those with apo E4, increase risk for heart disease: heart unhealthy.

Here are two studies that suggest that greater sterol absorption in people without sitosterolemia are at higher risk for heart disease:

Alterations in cholesterol absorption/synthesis markers characterize Framingham offspring study participants with CHD

Plasma sitosterol elevations are associated with an increased incidence of coronary events in men: results of a nested case-control analysis of the Prospective Cardiovascular Münster (PROCAM) study

Glucomania

As I suggested in a previous Heart Scan Blog post, a glucose meter is your best tool to:

1) Lose weight
2) Cure diabetes
3) Reduce or eliminate small LDL particles
4) Achieve anti-aging or age-slowing effects


But it means getting hold of a glucose meter and applying it in a very different way.

Diabetics typically check fasting morning glucose and again several times during the day to assess medication effects. But you and I can measure blood glucose to assess the immediate effects of food choices--two very different approaches.

The concept is simple: Check a blood glucose just prior to a food or meal of interest, then one hour after finishing.

Let's take two hypothetical breakfasts. First, oatmeal, a so-called "low-glycemic index" food. Slow-cooked, stone ground oatmeal with skim milk, a handful of walnuts, just a few blueberries.

Blood glucose just prior: 95 mg/dl
Blood glucose one hour after finish: 175 mg/dl

I made those numbers up, but this is a fairly typical response for many adults. (This is why "low-glycemic index" is an absurd notion.) This kind of response causes 1) glycation, the adverse effects of glucose modification of proteins that leads to cataracts, kidney disease, cartilage damage and arthritis, atherosclerosis, skin wrinkles, etc., 2) high insulin response that cascades into fat deposition, especially visceral fat ("wheat belly"), and 3) glucotoxicity, i.e., direct damage to the pancreas that can, over years, lead to diabetes.

Next day, let's try a breakfast of 3-egg omelet made with green peppers, sundried tomatoes, and olive oil.

Blood glucose just prior: 95 mg/dl
Blood glucose one hour after finish: 93 mg/dl

This is a meal of virtually zero-glycemic index. This kind of response triggers none of the effects experienced following the oatmeal. Repeated over time and you fail to trigger glycation, you stop provoking insulin, and visceral fat mobilizes rather than accumulates: you lose weight, particularly around the middle.

We therefore aim to keep the one-hour blood glucose 100 mg/dl or less. If you start with a high fasting blood glucose of, say, 118 mg/dl, then we aim to keep the one-hour after-eating blood glucose no higher than the pre-meal.

It works. Plain and simple.

This makes the primary care docs crazy: "How dare you check your blood sugar! You're not diabetic." In truth, blood glucose meters are relatively simple devices to use. The test strips and lancets will cost a few bucks. (The meters themselves are either low-cost or free, just like Gillette sometimes sends you a beautiful new razor for free but expects you to buy the blades). These are direct-to-consumer products. While a prescription written by your doctor for a glucose meter and supplies helps insurance cover the costs, you can easily get these devices without a prescription. Some stores, like Target, keep their devices out on the shelves with the shampoo and bath soap.

Warning: Anyone taking diabetes drugs will have to consult with their doctors about the safety of such an approach. Because this approach can actually cure diabetes in some people, if you are taking some diabetes drugs, especially glyburide, glipidize, and glimepiride, you can experience dangerously low blood sugars, just as any non-diabetic taking these drugs would.

Diarrhea, runny noses, and rage: Poll results

Here are the results of the week-long poll asking the question:

Have you experienced a wheat re-exposure syndrome?
Yes, undesirable gastrointestinal effects 223 (41%)

Yes, asthma or sinus problems 51 (9%)

Yes, joint pains and/or swelling 85 (15%)

Yes, emotional or other nervous system effects 59 (10%)
No, nothing, nada  107 (19%)

No. Wheat is sacred and you're all nuts  13 (2%)


There are several interesting observations to make from this informal poll. First, as I have observed, the most common wheat re-exposure syndrome is gastrointestinal, usually involving cramps, diarrhea, and lame explanations to your dinner partner.

Second most common: joint pains and/or swelling.

Third: asthma or sinus congestion.

The incidence of emotional or nervous system effects surprised me a bit. I didn't expect 10% of people to share this effect. This is an effect I also experience personally, along with the gastrointestinal consequences.

To be sure, this is a skewed poll, since many people likely come to this blog in the first place because of such issues. But I was nonetheless impressed with the relatively modest proportion of people who did not share such a re-exposure syndrome: only 19%.

Beyond the interesting numbers provided by readers, a good many also provided some fascinating and graphic comments. Here's a sample:

Reflux -- starts a day later and goes for up to a week. And Bloat:2-5 inches on my waistline in a day, lasting up to three. Miserable. And why, having experienced this once, have I done it often enough to verify the connection with certainty? I am working on that one.

Wheat increased hunger with even with only a small amount. Crackers in soup was enough to set it off.

Also, when I was trying to get off wheat, I noticed that 2 eggs and 2 bacon and I could go 5 hours before hunger, or 2 eggs and 2 bacon and toast was good for three hours before hunger. That was the final step to giving up wheat. Now three years and 59 Kg [130 lbs!] loss later, there is no doubt in my mind that wheat is evil, and I do not regard it as suitable for human food. I speculate that it increases ghrelin or cortisol.

For me, in the two years since I began eating Gluten-Free (Low Carb for 6 years), the few times I've had re-exposure to wheat, I've experienced fast onset and intense abdominal pain (known exposure during the daytime) and heartburn, indigestion, intense nausea, and disrupted sleep (exposures during evening meal not discovered until the next day).

My husband wants to think he's fine with wheat (though I know that he has at least one gene that predisposes to celiac), but IMO, he isn't. He eats no wheat at home because that's the default, and he's OK with that. But if he goes out to dinner at a restaurant that serves "good" artisan bread, he will indulge in a few bites (he does restrict his carb intake, so it's still a limited amount). More often than not, he will sleep fitfully on those nights, snore more, and wake in the night with indigestion. He wants to bury his head in the sand and will only acknowledge the discomfort being due to eating too many carbs, not the wheat itself. I notice he sleeps fine if he eats a small amount of potato or rice. Go figure.

Our 12 yo son has been eating GF for two years also. About 6 months into GF, he unknowingly ate wheat a number of times (licorice candy laces at a friend's house), which resulted in outbreaks of canker sores in his mouth each time. He also exhibits mood and behavior changes when he eats wheat, which is what prompted me to test him for gluten intolerance in the first place.

Mark said:
If I go for 3-4 days without wheat, grains or sugar and then go out and binge on a pizza and ice cream or something like that I become explosive within 20 minutes to an hour. It's like a wheat and sugar rage.(I'm not saying this is an excuse for rage, I'm saying it has happened to me and I believe partly do to re-exposure) It seems the combination of the wheat plus sugar can be the worst.

I get red rashes around my neck sometimes right away and sometimes up to a day or later and sometimes get bad diarrhea. 
I think it can be almost dangerous to cut things like gluten and sugar suddenly out of the diet without being very serious about keeping them out. I have found it very hard to cut out wheat without binging on it later after 4 or 5 days. I don't believe that my symptoms are just psychological either.

I was also diagnosed with ADHD as a young kid and then rediagnosed with adult ADHD by 3 different doctors. I also have bouts of mania at times too. I am considering trying to go completely gluten/refined carbohydrate free to see if it helps with the symptoms and gives me some relief.

I have never been tested for celiac or gluten intolerance but I would like to be. I think it would help explain to my girlfriend, family and friends why I can't go out and eat pizza or have a beer or ice cream. Right now they all think I'm a hypochondriac. At times I have experienced an intense fatigue the next day like I can't wake up and also sharp pains in my body and headaches.

I ditched wheat a year ago after my wife was diagnosed celiac. I immediately experienced a number of health improvements (blood lipids, sleep, allergies, etc.).

Fast forward: We all suffered some inadvertent wheat exposure yesterday via some chocolate covered Brazil nuts (of all things). This accidental A-B-A experimental design resulted in the following:

1. My celiac wife experienced what she calls "the flip" within an hour of exposure (i.e., intense GI distress).
2. My five-year old son went to bed with some wicked reflux.
3. I woke up with some twinges in my lower back and an ache in my football-weary left shoulder. I was also complaining to my wife about fuzzy-headedness that refused to respond to caffeine or hydration. I could only describe it as "carb flu"...

And then I read your post!

Anne said:
Depression, agitation and brain fog if I get glutened. Some times this comes with abdominal pain and a rash on my back - I think it is dose dependent. Cross contamination with wheat is a big issue when eating out. Needless to say, I eat out infrequently and then try to stick with the restaurants that are the most aware of gluten issues.

Terrence said:
Several weeks ago, I started Robb Wolf's 30 day challenge.

The first two weeks were brutal - calling it a withdrawal flu was a massive understatement. So, I thought I would try some wheat and see what happened (could not be worse, I thought). Well, it was.

I still felt extremely crappy, but I was now MASSIVELY GASSY - AMAZINGLY GASSY, for about 48 hours - flatulence on wheels, in spades. I did not go out at all in those 48 hours - when the gas came on, it went out, LONG, and QUICKLY and LOUDLY.

I am easing back into wheat and grain free. I am gluten free today and tomorrow (Sunday and Monday). I expect to try a small amount of wheat on Thursday, then maybe a little more the following Thursday.

Donald said:
I have limited wheat consumption severely over the last 8 months. I have lost 120 pounds, no longer have bouts of illness, asthma, depression, or low energy. I also take vitamin D and other supplements that have helped (many are from your blog recommendations).

Last week I ate a small piece of cake and dessert pizza. Shortly thereafter I started sneezing, had a scratchy throat, and runny nose. I called off sick the next day for fear of being contagious. My symptoms subsided quickly and I am now attributing them to the processed flour eaten at my work luncheon. I think it was an allergic reaction since I recall having much more severe symptoms fairly regularly in my wheat eating days. Those were attributed to an "allergy" of unknown origin back then.

John said:
I suffered from Ankylosing Spondylitis, Iritis, Plantar Fasciits, etc for a number of years. I restricted carbs, especially wheat and I've been symptom free for the past two years now.

Lori said:
I found wheat to be one of the worst things for giving me gas bloating and acid reflux, and I'd had sinus and nasal congestion my whole life. When I ate that cookie, it just re-introduced old problems. I can occasionally eat a gluten-free, grainy goody at my party place without any side effects. I also have a little sprouted rice protein powder every day.

Another odd thing about wheat: it was hard for me to stop eating it once I started. I could go through a whole box of cookies in one sitting, even though I wasn't a binge eater. But I can have a couple of gluten-free cookies and stop.

Paul said:
Except for one slip up this recently past holiday season, I've been sugar-grain-starch free since July 2008. Mental fog was the most noticable re-exposure symptom I had.

My mom has had the worst acid-reflux for 40-plus years. It had become so bad that she was on three medications just to deal with the symptoms. After much training and coaxing, I finally got across to her 
how to totally get off wheat. Not at all to my surprise, after being wheat free for a few weeks, she lost weight and her acid reflux was GONE!

But she had been addicted to wheat for so long, she relapsed, and the reflux fire soon returned. Wheat must be akin to heroin with some people. Even though they know it's very bad for them, they can't help themselves.

Onschedule said:
Re-exposure often leads to diarrhea for me, or such a heavy feeling of tiredness that all I can do is lay down and pass out. A local pizzeria makes a darn good pie, but since I started practicing wheat-avoidance, I can't keep my eyes open after eating there. I can't say for sure that it's the wheat causing it, but definitely something in the crust. Diarrhea, on the other hand, is definitely triggered by the wheat for me.

My mom complained of gastric reflux for years, but never filled the prescriptions that her doctors would give her. I suggested wheat-avoidance- gastric reflux disappeared within 3 days and hasn't returned (has been 6 months now). I've already commented elsewhere on this blog about how much weight and bloating she has lost...

Steve said:
Interesting that I should sit down, turn on my computer and find your poll. Having gone several weeks, maybe months, avoiding gluten, I took my daughter and her boyfriend out to eat because my wife has been working late at the office lately. Although I was thinking I would just eat my steak and chicken, I succumbed to the temptation of eating about a dozen greasy, breaded shrimp that my daughter and her boyfriend ordered. It's 1:39am and I still do not feel sleepy. My left nostril is completely blocked, my stomach feels bloated, really, really full and I've been burping. In your poll I checked sinus problems but could have chose gastrointestinal or nervous problems just as well. 


A few weeks ago my daughter brought home a pizza and, once again, despite my knowing that I shouldn't, I ate a couple of pieces. I was sick for two days. The pain in what I think was my transverse colon was so bad I thought I might have to go to ther emergency room. Before I ate the pizza I had never gone grain-free that long before. I did this after reading Robb Wolf's book. 


I AM CONVINCED. No more wheat for me! Please, Lord, give me strength.

LV said:
What don't I experience! I typically avoid wheat (and gluten for that matter) as I'm pretty sure it makes me sick, but when I slip (or someone else slips me some) I end up with massive amounts of joint swelling and tenderness, diarhea, cramping, gas, bloating and brain fog. I'm absolutely miserable. Just that alone is enough to keep me off gluten. I have RA, so if I have repeated exposures I'll have a flare which SUCKS!

The perfect Frankengrain

Pretend I'm a mad food scientist. I'd like to create a food that:

1) Wreaks gastrointestinal havoc and cause intractable diarrhea, cramps, and anemia.
2) Kills some people who consume it after a long, painful course of illness.
3) Damages the brain and nervous system such that some people wet their pants, lose balance, and lose the ability to feel their feet and legs.
4) Brings out the mania of bipolar illness.
5) Amplifies auditory hallucinations in people with paranoid schizophrenia.
6) Makes people diabetic by increasing blood sugars.
7) Worsens arthritis, such as osteoarthritis and rheumatoid arthritis.
8) Triggers addictive eating behavior.
9) Punishes you with a withdrawal process if you try to remove it from your diet.

I will develop a strain that is exceptionally hardy and tolerates diverse conditions so that it can grow in just about any climate. It should also be an exceptionally high yield crop, so that I can sell it cheaply to the masses.

Now, if my evil scheme goes as planned, I will then persuade the USDA that not only is my food harmless, but it is good for health. If they really take the bait, they might even endorse it, create a diet program around it.

Dag nabit! Such a plan has already been implemented. Another evil food scientist already beat me to the punch. The food is called wheat.

Diabetes: A study in aging

Diabetics experience long-term health difficulties, including atherosclerosis/heart attacks, peripheral vascular disease, hypertension, cataracts, kidney disease, neuropathies, male erectile dysfunction, osteoarthritis, and colorectal cancer. They also die, on average, 10 years earlier than non-diabetics.

In effect, diabetics compress their lives into a shorter period of time. They experience all the "complications" of aging at a younger age. People without diabetes, of course, can develop atherosclerosis, cataracts, kidney disease, etc., but they tend to do so later in life compared to diabetics.

One index of the rate of aging (but not chronologic age itself) is hemoglobin A1c, or HbA1c, a "moving average" of glycated hemoglobin, i.e., glucose-modified hemoglobin. Blood glucose glycates hemoglobin linearly and irreversibly; measuring HbA1c thereby provides an index of the last 60 or so days average blood glucose.

To put HbA1c values into perspective:

Average HbA1c of hunter-gatherers: 4.5%
Average HbA1c for Americans: 5.6%
American Diabetes Association definition of diabetes: 6.5% or greater
American Diabetes Association definition of adequate control of diabetes: 7.0% or less

Why do diabetics age faster? There are likely several reasons. One important reason is glycation, as indexed by HbA1c. Glycated proteins in the lens of the eye causes cataracts. Glycated proteins in cartilage leads to arthritis. Glycated LDL particles (apo B) leads to atherosclerosis. Glycated nerve cells causes neuropathy. And so on.

If glycation underlies many of the phenomena of aging, then we might surmise that:

1) The less you glycate, the slower you age.
2) The more you glycate, the faster you age.

Therefore, the higher the HbA1c, the faster you are aging.

What foods increase HbA1c? Carbohydrates. That bowl of slow-cooked, stone ground oatmeal? A one-hour after-eating blood sugar of 170 mg/dl is common. Your doctor says that's okay because it's below 200 mg/dl and you don't "need" medication yet.

Fish oil: The natural triglyceride form is better

If you have a choice, the triglyceride form of fish oil is preferable. The triglyceride form, i.e., 3 omega-3 fatty acids on a glycerol "backbone," is the form found in the body of fish that protects them from cold temperatures (i.e., they remain liquid at low ambient temperatures).

Most fish oils on the market are the ethyl ester form. This means that the omega-3 fatty acids have been removed from the glycerol backbone; the fatty acids are then reacted with ethanol to form the ethyl ester.

If the form is not specified on your fish oil bottle, it is likely ethyl ester, since the triglyceride form is more costly to process and most manufacturers therefore boast about it. Also, prescription Lovaza--nearly 20 times more costly than the most expensive fish oil triglyceride liquid on a milligram for milligram basis--is the ethyl ester form. That's not even factoring in reduced absorption of ethyl esters compared to triglyceride forms. Remember: FDA approval is not necessarily a stamp of superiority. It just means somebody had the money and ambition to pursue FDA approval. Period.

Taking any kind of fish oil, provided it is not overly oxidized (and thereby yields a smelly fish odor), is better than taking none at all. All fish oil will reduce triglycerides, accelerate clearance of postprandial (after-eating) lipoprotein byproducts of a meal (via activation of lipoprotein lipase), enhance endothelial responsiveness, reduce small LDL particles, and provide a physical stabilizing effect on atherosclerotic plaque.

But if you desire enhanced absorption and potentially lower dose to achieve equivalent RBC omega-3 levels, then triglyceride forms are better.

Here are cut-and-pasted abstracts of two of the studies comparing forms of fish oil.

Bioavailability of marine n-3 fatty acid formulations.

Dyerberg J, Madsen P, Moller JM et al. 
Department of Human Nutrition, Faculty of Life Sciences, University of Copenhagen, Copenhagen, Denmark.

Abstract

The use of marine n-3 polyunsaturated fatty acids (n-3 PUFA) as supplements has prompted the development of concentrated formulations to overcome compliance problems. The present study compares three concentrated preparations - ethyl esters, free fatty acids and re-esterified triglycerides - with placebo oil in a double-blinded design, and with fish body oil and cod liver oil in single-blinded arms. Seventy-two volunteers were given approximately 3.3g of eicosapentaenoic acid (EPA) plus docosahexaenoic acid (DHA) daily for 2 weeks. Increases in absolute amounts of EPA and DHA in fasting serum triglycerides, cholesterol esters and phospholipids were examined. Bioavailability of EPA+DHA from re-esterified triglycerides was superior (124%) compared with natural fish oil, whereas the bioavailability from ethyl esters was inferior (73%). Free fatty acid bioavailability (91%) did not differ significantly from natural triglycerides. The stereochemistry of fatty acid in acylglycerols did not influence the bioavailability of EPA and DHA.

Enhanced increase of omega-3 index in response to long-term n-3 fatty acid supplementation from triacylglycerides versus ethyl esters.

Neubronner J, Schuchardt JP, Kressel G et al. 
Institute of Food Science and Human Nutrition, Leibniz Universität Hannover, Am Kleinen Felde 30, Hannover, Germany.

Abstract

There is a debate currently about whether different chemical forms of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are absorbed in an identical way. The objective of this study was to investigate the response of the omega-3 index, the percentage of EPA+DHA in red blood cell membranes, to supplementation with two different omega-3 fatty acid (n-3 FA) formulations in humans. The study was conducted as a double-blinded placebo-controlled trial. A total of 150 volunteers was randomly assigned to one of the three groups: (1) fish oil concentrate with EPA+DHA (1.01?g+0.67?g) given as reesterified triacylglycerides (rTAG group); (2) corn oil (placebo group) or (3) fish oil concentrate with EPA+DHA (1.01?g+0.67?g) given as ethyl ester (EE group). Volunteers consumed four gelatine-coated soft capsules daily over a period of six months. The omega-3 index was determined at baseline (t(0)) after three months (t(3)) and at the end of the intervention period (t(6)). The omega-3 index increased significantly in both groups treated with n-3 FAs from baseline to t(3) and t(6) (P < 0.001). The omega-3 index increased to a greater extent in the rTAG group than in the EE group (t(3): 186 versus 161% (P < 0.001); t(6): 197 versus 171% (P < 0.01)). Conclusion: A six-month supplementation of identical doses of EPA+DHA led to a faster and higher increase in the omega-3 index when consumed as triacylglycerides than when consumed as ethyl esters.

Diarrhea, asthma, arthritis--What is your wheat re-exposure syndrome?

Have you experienced a wheat re-exposure syndrome?

As I recently discussed, gastrointestinal distress--cramps, gas, diarrhea--is the most common "syndrome" that results from re-exposure to wheat after a period of elimination.

Others experience asthma, sinus congestion and infections, mental "fogginess" and difficulty concentrating, or joint pains and/or overt swelling.

Still others say there is no such thing.

Let's take a poll and find out what readers say.

Marathoners, triathletes, and heart disease

Curious thing: People with lipoprotein(a) gravitate towards elite levels of exercise.

I tell my lipoprotein(a) patients that, if they want to see a lot of other people with lipoprotein(a), go to a marathon or triathlon.

This effect applies more to males than to females, just as the fascination with numbers seems to be confined to men, too. That's why I've posted in past about the "prototypical" lipoprotein(a) male.

I believe this is a big part, perhaps the only, reason why there seems to be a modest increased risk for cardiovascular events despite high exercise levels in marathoners. It has nothing to do with the exercise itself; it has to do with the kind of people who choose to exercise at this level.

The best fish oil

The best fish oils available are the liquid forms. Contrary to many people's expectations, the best liquid fish oils have no fishy odor or taste.

I use a lot of liquid fish oils because of the higher doses we use in the Track Your Plaque program, as well as our strategy of high-dose fish oil to reduce lipoprotein(a). Women, in particular, don't like taking the oodles of capsules required to achieve the higher doses we need. So the ladies really like the liquid forms.

The best liquid fish oils are non-fishy, highly-concentrated, and come in the better absorbed triglyceride form. Many capsules, including prescription Lovaza, are the less well-absorbed ethyl ester form. Several studies, such as this one, have now demonstrated that the naturally-occurring triglyceride form yields higher blood (RBC) levels of omega-3 fatty acids, likely due to more efficient digestion via pancreatic lipase.

While there are many good forms of fish oil and only a few bad, these are the best of the best:

Pharmax
The Pharmax Finest Pure Fish Oil with Essential Oil of Orange contains 1800 mg EPA + DHA per teaspoon. This is the preparation I've been taking.

Nordic Naturals
The Nordic Naturals lemon-flavored ProOmega Liquid contains 2752 mg EPA + DHA per teaspoon, the most concentrated of any fish oil I've seen.

(This list is not exclusive. These are just two brands I've used extensively with good results.)

These highly-concentrated, triglyceride forms are more expensive, due to their concentrated nature. 1 teaspoon Pharmax fish oil, for example, provides an equivalent quantity of omega-3 fatty acids as 6 standard fish oil capsules on a milligram for milligram basis, but more like 8 to 9 capsules when absorption efficiency is factored in. The triglyceride form is also more laborious to manufacture. On our Track Your Plaque Marketplace, our Pharmax 500 ml runs $58.95 list. (500 ml provides 100 teaspoons or 600-capsule equivalent.)

Note that, minus the protection of the capsule, liquid fish oils will oxidize if not refrigerated. So be sure to keep your liquid fish oil in the fridge.

Goodbye, Dr. Jarvik

HeartWire, the news service of www.theheart.org, posted the following report:

Pfizer pulls Lipitor ads featuring Dr Robert Jarvik in HeartWire

New York, NY - After a series of questions and attacks over its choice of Dr Robert Jarvik to endorse Lipitor in a series of TV commercials, Pfizer has announced that it is withdrawing the ads. As previously reported by heartwire, Jarvik invented the first artificial heart, but he is not a cardiologist, nor does he hold a medical license—factors that drew criticism from detractors and made him and Pfizer a target of a US House Committee on Energy and Commerce investigation into celebrity endorsements in direct-to-consumer advertisements.

In a January 2008 statement, committee chair Rep John D Dingell (D-MI) observed: "Dr Jarvik's appearance in the ads could influence consumers into taking the medical advice of someone who may not be licensed to practice medicine in the United States. Americans with heart disease should make medical decisions based on consultations with their doctors, not on paid advertisements during a commercial break."

Complaints about Jarvik went up a notch this month when the latest ad in the series depicted the inventor rowing a racing scull across a lake, despite the fact that Jarvik himself does not row and the commercial used a body double.


This is typical pharmaceutical industry sleight-of-hand, now you see it, now you don't, that has come to define their policies. And this is just the stuff that comes to light because of some obvious blunders. We can only begin to imagine what sorts of other shenanigans have been swept under the rug, especially adverse effects of drugs that never made it to the light of publication.

Is this just another example of how direct-to-consumer advertising has backfired? I now have patient after patient tell me that they have been so overwhelmed and fed up with TV and magazine ads for drugs that they



Other media outlets have reported that Jarvik was guaranteed $1.35 million for the ads and that Pfizer spent $258 million on Lipitor advertisements between January 2006 and September 2007.

Hammers and nails

I'm sure you've heard the old saying that,

To a man with a hammer, everything looks like a nail.


It couldn't be truer than in heart procedures (the man with the hammer) and heart disease (the nail).

What does it take in 2008 to become an interventional cardiologist trained in all the techniques of angioplasty, stenting, intracoronary ultrasound, etc.? Start with your undergraduate degree (4 years), then medical school (another 4 years), then training in internal medicine (3 years), then general cardiology taining (3 years), then an additional year in interventional cardiology. Each step along the way also involves competing for these spaces, a process that requires much time, money, and sweat.

The total time investment is 15 years after high school. Many if not most college students graduate with debt. Pile on the substantial cost of medical school. Training after medical school pays a modest salary, enough for a single person. Many trainees by then have spouses and a family, would like to buy a house, have bills to pay. (I managed to buy my first house for $69,000 in Columbus, Ohio and paid my mortgage by sleeping only every other night and moonlighting on my off nights.)

By the time the interventional cardiologist-in-training finishes his/her 15 years, they are hungry for a hefty increase in income. After such a time and money investment, I do believe that there is at least some justification for generous income for the years of work involved.

Back to our hammer and nail metaphor. Not only do we now have a man or woman with a hammer, but a really expensive hammer that required a substantial amount of effort to obtain. Now, our hapless hammer-bearer is desperate to see everything in sight as a nail.

You're seen in consultation by this fresh interventional cardiologist in practice for only a few years. Guess what he/she advises? Go straight to the catheterization laboratory, of course. Throw in the fact that insurance reimbursement is most generous for heart procedures, far more than for consulting in the office, doing a stress test, or other simpler, non-invasive tests, and the incentives are clear.

The system, you see, is set up to follow such a path. The path to the cath lab is heavily incentivized, paths in the other direction discouraged, disparaged, or just ignored.

My message: Don't get nailed.

What is abnormal?

What is abnormal?

You'd think that the answer would be easy and straightforward.

However, consider these instances of medical findings that I have witnessed fall repeatedly into the "normal" category:

Diameter of the thoracic aorta: 4.5 cm

Mild coronary plaque by heart catheterization

Carotid plaque of 30-50%


Why isn't a thoracic aorta (the big artery in your chest) of 4.5 cm normal? Because it can be expected to increase in diameter by about 2.5 mm (0.25 cm) per year. Even at its current diameter, it means that stroke risk is greater, since enlarged aortas are diseased aortas that commonly accumulate atherosclerotic plaque with potential to fragment and shower debris to the brain. It means that high blood pressure and/or cholesterol/lipoprotein abnormalities have been uncorrected for years that have allowed the aorta to enlarge.

How about "mild coronary plaque"? Followers of the Track Your Plaque program already know the answer to this one. Mild plaque does not mean mild risk. In fact, most plaques that cause heart attack are mild plaques, not severe blockages. While severe blockages can provide symptom warning and are detected by stress tests, it's the mild blockages that rupture without symptom warning and cause heart attack. So "mild coronary plaque" is no less dangerous than severe coronary plaque.

Likewise, carotid plaque of 30-50%, while it doesn't justify surgery, can grow within just a few years to a severity that allows it to fragment and shower debris to the brain, i.e., a stroke. As with the enlarged aorta, it means that multiple causes of carotid plaque are likely active, including high blood pressure and cholesterol or lipoprotein abnormalities.

Then why would any of these findings be labeled "normal"?

Simple. In the minds of many physicians, if a condition doesn't pose immediate risk, or if it doesn't qualify for surgical "correction," then it is labeled "normal" or "mild."

Thus, an aorta of 4.5 cm cannot justify surgical replacement until it achieves a diameter of 5.5 cm. It is therefore labeled "normal."

"Mild coronary plaque" does not justify insertion of stents or performance of bypass surgery. It must therefore be "normal."

Carotid plaque over 70% is surgically removed, but not 30-50%. 30-50% is therefore "normal."

The tragedy is that many "normal" or "mild" findings, if cast in the proper light, could lead to corrective strategies that could prevent danger long-term or keep surgery from becoming necessary.

The enlarged aorta, for instance, could be stopped and an aneurysm (defined as 5.5 cm or greater) could be prevented, along with dramatically reducing risk for stroke. Carotid plaque, more so than coronary plaque, is a controllable and manipulable condition that should trigger a program of prevention and reversal. Instead, it usually generates advice to have another ultrasound in a year to see if it has yet achieved severity sufficient to justify surgery.

Of course, "mild coronary plaque" is the reason for the Track Your Plaque approach, a chance to seize control over this disease years or decades before procedures are necessary and reduce danger now, not years from now.

Niacin and hydration

Many people know about niacin's curious effect of the "hot flush," a feeling of warmth that covers the chest and neck, occasionally the entire body.

However, many people are unaware of the fact that hydration can block this effect. In fact, many people who were not advised of this will come to the office describing miserable experiences with niacin--hot flushes that last for hours, intolerable itching, etc.--only to experience little or none of these effects with generous hydration.

The vast majority of the time, two 8-12 oz glasses of water when the hot flush occurs will eliminate the flush within a few minutes.

Sometimes, the hot flush will occur many hours after taking niacin. Nine times out of ten, this delayed effect is also due to poor hydration. For instance, you might be engrossed in your work and forget to keep up with fluid demands. Or, it may be warm and you've lost fluids through sweating. That's when you begin to feel the hot flush creep up on you.

The cure: Lots of water. In this situation, in which you have allowed dehydration to develop, it may require more than two big glasses. Relief from the flush may also take more time, but it still works nearly every time.

On those rare occasions when water by itself is insufficient, then an adult (325 mg), uncoated aspirin or 200 mg ibuprofen can also be used to accelerate relief.

Why go to some much bother? Well, niacin remains the best agent we have for reduction of small LDL, raising HDL (although vitamin D is proving to be a powerful competitor in this arena), and reducing lipoprotein(a). How much do statin drugs contribute to these effects? Very little, if at all.

Several drug manufacturers are also working on "antidotes" to the hot flush effect of niacin that will be packaged within the niacin tablet. Naturally, it will also boost the cost up many times higher.

In the meantime, if or when you experience the niacin hot flush, just think: Put out the "fire" with plenty of water.

Let me float an idea

I'd like to float an idea.

The Track Your Plaque program is a fee-for-membership website. We chose this method of covering our costs--website development, graphics, software coding, etc.--since we do not accept advertising. I do believe that not having any advertising on our website has kept us impartial and unbiased--we mean what we say and not because we are selling something.

But there's a downside to assessing a membership fee: It limits the number of people who are willing or able to access the information. It also limits the dissemination of these concepts, due to such phenomena as limited content exposure to internet search engines.

Actos, Avandia, and vitamin D

Up until a few years ago, if a patient showed signs of the metabolic syndrome/pre-diabetes, or early diabetes, I would often prescribe one of the drugs, Actos (pioglitazone) or Avandia (rosiglitazone), known as the thiazolidinediones, or TZD's for short. Although I do not manage diabetes, I was witnessing a flood of patients with pre-diabetic patterns that inhibited correction of lipoprotein patterns. So I saw the TZD's as a means of potentially assisting with correction of these abnormalities.

My rationale back then was that many people with metabolic syndrome struggled to raise HDL cholesterol, reduce triglycerides, reduce small LDL, reduce the inflammatory measure c-reactive protein (CRP), as well as reduce blood sugars towards the normal range. The TZD's partially corrected these phenomena.

But over the last 2 1/2 years, I haven't written a single prescription for these agents since I've added vitamin D to the regimen.

Vitamin D in my experience in the Track Your Plaque approach:

--Raises HDL--far more than the TZD's ever did.

--Reduces small LDL

--Reduces triglycerides

--Reduces c-reactive protein

--Reduces blood pressure

--Reduces blood sugar

In other words, vitamin D appears to not only reproduce many of the effects of the TZD's, but exceeds the effects. The effects are often so wonderful that I've taken many people off their TZD's.

Vitamin D, of course, also provides numerous benefits for bone health, reduction of cancer risk, and other health benefits that the TZD's simply cannot compete with. Vitamin D also lacks the quite substantial side-effects of TZD's: water retention and weight gain (around 8 lbs in the first year of treatment), possible increase in risk for heart attack (Avandia), definite increased likelihood of congestive heart failure in those prone to it.

How about cost? Actos goes for about $2 per pill (30 mg tablet). Vitamin D in the gelcap form (the only form we use) costs around $0.05 per capsule--5 cents. That's a 40-fold difference in price for what I would regard as an inferior--substantially inferior--product.

Throw into the mix a dramatic reduction or elimination of wheat products and other high-glycemic index foods, and all the phenomena of the metabolic syndrome and its associated lipoprotein patterns show even more improvement or full reversal.

In fact, with this approach we are seeing record-setting magnitudes of correction of these parameters every day. Getting HDL, for instance, into the 60 mg/dl or 70 mg/dl range has never been so easy.

What if heart scans become obsolete?

What will we do if or when CT heart scans become outdated and something better comes along?

Heart scans are, after all, our principal tool for detection and precise quantification of coronary atherosclerotic plaque. They provide the basis for the Track Your Plaque program: serial heart scans to track progression or regression of coronary plaque.

So what the heck will we do if heart scans become obsolete, if some other technology proves superior for precise lengthwise quantification of coronary plaque?

Simple: Then we will convert to that measure.

Say, for instance, that in 5 years, MRI advances to the point where it is quick and precise, despite the rapid motion of the heart that has, in past, caused this technology to stumble for plaque quantification. Instead of obtaining a heart scan score of, say, 350, instead an MRI might yield information like:

Calcium volume: 350 cubic mm
Soft plaque elements: 200 cubic mm
Fibrous tissue: 700 cubic mm

In other words, while a CT heart scan provides a calcium score that serves as a surrogate measure of total plaque volume, perhaps the next wave of technology will directly measure total plaque volume.

Don't CT coronary angiograms already measure total plaque volume?

No, they definitely do not. At present, the best they can do is visualize the non-calcific elements and suggest the diameter reduction created by plaque at a specific point. Thus, results like "50% blockage in the mid-left anterior descending." What they do not provide is a lengthwise total volume of plaque and all its elements. Perhaps some software manipulation in future will yield such information (and I think it will, though I personally have been unable to accomplish it).

So neither the Track Your Plaque program nor the Heart Scan Blog are necessarily bound to heart scans. But heart scans, in 2008, remain the number one best tool for plaque quantification that is easy, precise, available, and inexpensive. For those reasons, CT heart scans continue to serve as the basis for these programs, and not CT angiograms, MRI, or other non-quantitative technology.

Scare tactics

Does the media engage in scare tactics?

Read the headlines in local newspapers, and you'd believe that your friends and neighbors are dropping like flies, all victims of heart attacks.

I occasionally peruse the headlines run in newspapers and magazines around the U.S. by subscribing to a feed service through Google. For the phrase, "heart attack," you can get a sample of what is being said around the country about people having heart attacks.

What continues to impress me is just how far off a truly constructive and helpful message the media provides every day. Not only are they guilty of delivering a flawed message, they also favor headlines and stories that scare the heck out of people. "This could happen to you!"

Is it just the quest for headlines that grab readers' attentions? Is there some complicity with the medical systems that pay significant advertising revenues for their heart disease programs and hospitals?

I doubt such complicity exists to any substantial degree. But the fact remains: Every day across the U.S., the media does an effective job of scaring the heck out of the public--enough for you to run to your doctor or hospital to find out if you, too, could fall victim to heart disease. A stress test, perhaps heart catheterization, three stents or bypass often results.

In effect, these headlines make great hospital PR, an inducement that flushes out the patient highly motivated to pursue further costly heart testing--whether or not it's needed.

A sampling:

Stress test could help prevent sudden heart attack

DAWN ZERA Times Leader Correspondent

Bob Schultz, 67, was feeling a persistent pain in his back, which he was pretty sure was caused by working on a deck for his son’s home.

But after the deck was finished, the pain was still there.

“It was nagging, but not enough to hurt,” Schultz said.

He visited his primary care physician, thinking maybe some muscle relaxants would be prescribed. The doctor sent him to a clinic in Tunkhannock to do a complete body CAT scan, and then had Schultz do a stress test. The on-site cardiac stress testing at a Geisinger Medical Group office in Tunkhannock showed that things did not look good: Schultz had a blockage. He was scheduled for a cardiac catheterization.

It was a surprise; a heart problem had not even crossed Schultz’s mind as a possible cause of his back pain.

“I had good cholesterol, have been the same weight for years, and had excellent blood pressure,” Schultz said.

He went for the catheterization at Geisinger Wyoming Valley, and there doctors discovered Schultz’s condition was even more serious. He had three blockages – 99 percent, 95 percent and between 80 and 90 percent.

“It shocked the living daylights out of everyone. It was surreal,” Schultz said.

The catheterization turned into open heart surgery that very same day.

The surgery was on a Tuesday, and he was home by Sunday. He never even had time to fully think about having the operation. And he had never experienced the typical warning signs of a heart problem, such as chest pain or shortness of breath.

“The doctors said I had the worst alarm system they’d ever seen,” Schultz said. “They probably saved my life, with me not knowing I had a problem.”

It also made him think about his brother, who had had been in good health but suddenly died in his 40s of a suspected heart attack.

“We never had any heart problems in our family, so we never believed it. But now I think, geez, it probably was true,” Schultz said.

His experience has served as a cautionary tale for friends and family. Just this past month, a friend specifically requested a stress test for himself.

“It sets off alarms in your circle. People think ‘if it can happen to him, it could happen to me,’ ” Schultz said. “It triggered people to think about what could happen to them.”



Firefighter Saves Heart-Attack Victim on D.C. Court

ABC News

A 30-year-old man suffered a heart attack while playing basketball on a D.C. court.

That's when a Brian Long's firefighter training kicked into action. The 25-year-old D.C. firefighter's team had just finished their pick-up league game Friday evening at Lafayette Elementary School's basketball court when the man stumble to the ground.

"He ran a few feet and collapsed again so I turned him over and I looked at him his eyes rolled back and he just stopped breathing," Long said.

Long began performing chest compressions and soon he was joined by Anthony Gadson, a pharmaceutical sales representative, who learned CPR years ago and starting assisting with mouth to mouth resuscitation.

"If that were me, somebody would've done the same thing for me, so I feel like I did what I was supposed to do," Gadson explained.

While Long and Gadson worked to keep the victim's heart going, all the players and spectators, including teammate and league commissioner Bob Johnson, gathered around the lifesaving effort.

"We gathered in a circle and one of the wives of one of the players just led us in this huge prayer," said Johnson.

"It makes me feel great," Long told ABC 7/NewsChannel 8. "I am just glad that I am a D.C. Firefighter."



Free Drugs After Heart Attack Would Save Money, Lengthen Lives
More patients would take recommended medications, study says


By Ed Edelson

MONDAY, Feb. 18 (HealthDay News) -- Eliminating the cost of medications for people who have heart attacks would lead to longer lives and lower overall medical costs, new research suggests.

"These are highly effective medications that are relatively inexpensive, and the events they are designed to prevent are extremely expensive," said study author Dr. Niteesh K. Choudhry, a researcher in the division of pharmacoepidemiology and pharmacoeconomics at Brigham and Women's Hospital in Boston and an assistant professor at Harvard Medical School. His report is published in the Feb. 19 issue of Circulation.

The study covered four drugs commonly prescribed after heart attacks -- aspirin, beta blockers, ACE inhibitors or angiotensin receptor blockers (ARBs), and statins. Use of those drugs is relatively low under the current system, in which people share the cost with Medicare or other health insurance plans, Choudhry said. For example, only 46 percent of people take beta blockers after heart attacks, and only 50 percent take cholesterol-lowering statins. Less than 20 percent of heart patients used all four of the medications, according to the study.

The model set up by Choudhry and his colleagues doesn't assume a major increase in compliance with prescriptions, because "cost is just one reason why patients do not take medications," he said, adding that relying on previous studies of drug cost and use, the model assumes an increase of about 14 percent, with perhaps 64 percent of people taking the medicines if they were free.

The result would be an increase in average survival after a heart attack, from the present 8.21 quality-adjusted life years to 8.56 years. "That is small in an absolute sense, but in an aggregate sense, it is very large," Choudhry said.

And medical costs over a lifetime would go down, from the current $114,000 to $111,600, the study added.

"This study adds to a growing body of research showing how important it is to reduce or eliminate patient co-payment for drugs," said Robert M. Hayes, president of the Medicare Rights Center in New York. "Medicare should take the lead in forging the creation of drug coverage that allows patients to get the medications their doctors consider vital."

"It certainly makes sense from the medical point of view," said Dr. Richard A. Stein, a professor of medicine at New York University. "Studies have shown that giving even middle-income people free drugs improves outcome. The greatest benefit will go to people in the lower socioeconomic and immigrant population."

But the study is theoretical, Stein noted. "One would like to see some real-world trial to determine whether this works in fact, whether providing free drugs without co-payment would make a difference, he said.

Such a study has begun at Harvard, Choudhry noted. His group is working with a major health insurer, not Medicare, in a trial that assigns some people to get medications without cost, while others will get the standard co-payment.

"It will take several years for us to get answers," Choudhry said. But similar investigations are being started by other medical insurers and corporations, he added.

The idea is potentially applicable to some other chronic conditions, such as congestive heart failure and diabetes, Choudhry noted. And, if the use of recommended medications after a heart attack goes up more than predicted by the model, "the cost savings would be phenomenal," he said.

Heart Attack Threatens Young, Old

BAKERSFIELD, Calif. -- Nearly 1.2 million men and women suffer a heart attack every year in the United States, according to the American Heart Association. However, not all of the victims are old.

Brian Connell considers himself a lucky guy. At the age of 39, he's physically active, he has a high-level job, and he is also a heart attack survivor. "I know I was overweight and obviously had some other risk factors against me," said Connell. "I wish I did more to prevent it, certainly."

Connell is doing plenty of things now. He met with a nutritionist and changed his diet. He gets regular exercise and takes medication to control his cholesterol. He also gets regular checkups.

Cardiologist Jeffrey Popma said it's not unusual to see younger heart attack patients. "We have dozens of patients in our system every year who have been under 40 years old who have suffered a major heart attack," said Dr. Popma.

Popma said getting medical help quickly is the key to survival. Connell said that is what made all the difference for him. And when people ask him if that was his first heart attack, Connell said he is quick to tell them it was his last heart attack.

The messages I take from such stories:

1) Get yourself to a hospital ASAP for any symptoms even vaguely suspicious of heart disease, because they will know what to do. You'll be doomed if you don't.

2) Hospitals and doctors are expert at saving you from the brink of disaster. The process, once you enter, is rapid and smooth and you will be eternally grateful.

3) Medicines save lives. You're going to die if you don't take medication.


As I've often said, one of the toughest battles of all in health and heart disease is sorting out fact from fiction. Unfortunately, the media continues to propagate the scare tactics that support the status quo of procedural heart care. Wittingly or unwittingly, they serve a $400 billion dollar a year gargantuan industry that remains hungry for growth.

Lost in the headlines are the messages that could have been included, like:

Heart disease detectable decades before disaster

Or:

"Heart disease preventable, reversible, and--curable?"

Which statin is best?

The statin drugs can indeed play a role in a program of coronary plaque control and regression.

However, thanks to the overwhelming marketing (and lobbying and legislative) clout of the drug manufacturing industry, they play an undeserved, oversized role. I get reminded of this whenever I'm pressed to answer the question: "Which statin drug is best?"

In trying to answer this question, we encounter several difficulties:

1) The data nearly all use statins drugs by themselves, as so-called monotherapy. Other than the standard diet--you know, the American Heart Association diet, the one that causes heart disease--it is a statin drug alone that has been studied in the dozens of major trials "validating" statin drug use. The repeated failure of statin drugs to eliminate heart disease and associated events like heart attack keeps being answered by the "lower is better" argument, i.e., if 70% of heart attacks destined to occur still take place, then reduce LDL even further. This is an absurd argument that inevitably encounters a wall of limited effects.

2) The great bulk of clinical data examining both the incidence of cardiovascular events as well as plaque progression or regression have all been sponsored by the drug's manufacturer. It has been well-documnted that, when a drug manufacturer sponsors a trial, the outcome is highly likely to be in favor of that drug. Imagine Ford sponsors a $30 million study to prove that their cars are more reliable and safer. What is the likelihood that the outcome will be in favor of the competition? Very unlikely. Such is human nature.

If we were to accept the clinical trial data at face value and ignore the above issues, then I would come to the conclusion that we should be using Crestor at a dose of 40 mg per day, since that was the regimen used in the ASTEROID Trial that achieved modest reversal of coronary atherosclerotic plaque by intravascular ultrasound.

But I do not advocate such an ASTEROID-like approach for several reasons:

1) In my experience, nobody can tolerate 40 mg of Crestor for more than few weeks, a few months at most. Show me someone who can survive and tolerate Crestor 40 mg per day and I'll show you somebody who survived a 40 foot fall off his roof--sure, it happens, but it's a fluke.

2) The notion that only one drug is necessary to regress this disease is, in my view, absurd. It ignores issues like hypertension, metabolic syndrome, inflammatory phenomena, lipoprotein(a), post-prandial (after-eating) phenomena, LDL particle size, triglycerides, etc. You mean that Crestor 40 mg per day, or other high-intensity statin monotherapy should be enough to overcome all of these patterns and provide maximal potential for coronary plaque reversal? No way.

3) Plaque reversal can occur without a statin agent. While statin drugs may provide some advantage in the reduction of LDL, much of the benefit ends there. All of the other dozens of causes of coronary atherosclerotic plaque need to be addressed.

So which statin is best? This question is evidence of the brainwashing that has seized the public and my colleagues. The question is not which statin is best. The question should be: What steps do I take to maximize my chances of reversing coronary atherosclerotic plaque?

The answer may or may not involve a statin drug, regardless of the subtle differences among them.

Lipoprotein(a)--neglected and unappreciated


Lipoprotein(a), or just Lp(a) to its close friends and neighbors, is among the most underappreciated and neglected of causes of coronary plaque. It's the Rodney Dangerfield of lipoproteins.

Lp(a) rarely gets diagnosed before people come to my office. They've often been through the ringer: doctors have thrown their hands up in frustration because of poor response to "standard" treatment (AKA statin drugs); the patient doesn't understand why they might be thin and active yet have the high blood pressure of someone 70 lbs heavier; they have heart disease despite wonderful cholesterol values.

One blood test and the answer becomes clear: They have Lp(a). It explains all these phenomena.

They why don't more physicians order this simple test? Why don't we hear more about this prevalent (1 in 5 people with coronary plaque have it) genetic pattern that accelerates risk for heart disease?

There are a number of reasons. But I believe the most powerful reason is simply that there is no big revenue-generating drug to treat it. Statins reduce LDL cholesterol to the tune of $27 billion dollars a year (2007 revenue). There's no such blockbuster for Lp(a). Of course, Niaspan represents the relatively anemic attempt to commercialize a pharmaceutical treatment for Lp(a), but side-effects and the lack of FDA trials for the Lp(a)-reducing indication have stalled its commercial success. (Efforts to block the flush with various products, by the way, may re-invigorate niacin as a pharmaceutical agent. The drug companies smell money here.)

Another reason for Lp(a)'s unpopularity: Though there are mounds of data that document--without question--that Lp(a) is an important risk for coronary disease and other forms of atherosclerotic disease, we lack treatment trials. For instance, niacin vs. placebo for 5 years, then count the number of heart attacks and deaths. We have numerous, repetitive, overlapping, redundant trials with statins adhering to this design. We have none for niacin and the treatment of Lp(a).

Niacin is also a pain in the neck for your doctor. He/she rapidly tires of the calls about the crazy and disconcerting flushing with niacin. Most are unaware that proper hydration reduces or eliminates the flush for the majority of people. It takes too much time and energy to educate people. (By the way, prescription Niaspan makes no mention of purposeful hydration. They only suggest the nonsensical "Take with a low-fat snack," i.e., snacks that actually counter the therpaeutic effects of niacin. What they should be saying is "take with a high-fat snack" like raw almonds, foods that facilatate the benefits of niacin.)

Should someone concoct a successful pharmaceutical treatment for Lp(a), it will make the news, headlines in health magazines and health sections of the newspaper will blare about how important Lp(a) is. Yet it has been there all along, frustrating people and their physicians.

In the Track Your Plaque experience, Lp(a) clearly 1) correlates with heart scan scores, 2) correlates with progression of heart scan scores without treatment, and 3) poses special challenges for treatment. Interestingly, some of our biggest failures have been with Lp(a), as well as some of our biggest successes. (Our current record holder for the largest percentage reduction in heart scan score has Lp(a).)

If you have coronary plaque, or if there is family risk of heart disease, then Lp(a), in my view, is an absolutely essential factor to test for. Yes, treatment poses challenges. But once you know who your enemy is, then you can focus your efforts on it. Not knowing whether or not you have it leaves your efforts unfocused and generally flawed.
