Super size me in little bits and pieces



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

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

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

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

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

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

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

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

View from the precipice


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

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

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

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

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

Organic Rice Krispies?



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

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

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

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

Nuts as functional foods

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

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

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




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

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

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

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

--Modest blood pressure reduction.

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

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

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

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

Can you tell the difference?

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

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

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

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

Stan's heart scan score: 0

Charles' heart scan score: 978

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

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

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

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

Statin agents and muscle aches

How common are muscle aches with the statin drugs?

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

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

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

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

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

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

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

More catheterizations would make me happy!

I received this fax today from a cardiologist seeking a position:

"I would prefer to perform as many interventions [stents, angioplasties, etc.] as possible..."

That about sums it up, doesn't it? The goal of this young man, trained in major universities including Columbia University, Harvard, and Emory, is not to pursue an avenue of investigation or healthcare that yields real answers. His goal is to perform as many procedures as possible.

This attitude is deeply ingrained in cardiologists. It's also shared by all procedural medical specialties: the drive to do more and more procedures. It's not because it does more good for the public, but it fulfills a primitive impulse to spread your influence, enlarge your territory, and--of course--make more money.

Personally, I find this impulse repulsive. The fact that this young cardiologist looking for a position is willing to make this statement out in the open demonstrates how widely accepted this attitude is. Imagine your cancer surgeon, looking for a new job, said, "I'm looking to remove as many tumors as I can."

My colleagues have lost sight of the fact that we're trying to reduce or eliminate disease, not enrich our pockets or service some primitive impulse to beat others at our game.

"I hate fish oil!"

I get this comment occasionally, usually from the fishy belching that can occur, rarely because of other crazy effects like rash, fishy body odor, etc.

In the vast majority, fish oil is a benign but wonderfully effective agent. Track Your Plaque followers know that fish oil, starting at 4000 mg per day of a standard 1000 mg capsule preparation, dramatically reduces triglycerides and thereby raises HDL, partially suppresses small LDL, and is the best agent available for reducing postprandial (after eating) abnormalities like IDL and certain VLDL fractions.

However, an occasional person (about 1 in 20) just doesn't like the effects. Are there alternatives? Fish oil packs such a wallop of beneficial effects that can not be replaced by any other single agent or lifestyle practice. For this reason, we have a number of easy strategies to enhance your tolerance for fish oil. (Of course, if your and/or you doctor determine that you're allergic to fish oil, then you should indeed avoid it; thankfully, this is rare.)

Helpful strategies include:

--Refrigerate fish oil capsules--this cuts back on fish belching.
--Take only with meals. This also may increase fish oil's benefits on suppressing after-eating lipoprotein abnormalities.
--Take an enteric-coated preparation--this delays breakdown of the tablet/capsule, making fishy belching less of an issue. Sam's Club has an inexpensive preparation.
--Take liquid fish oil. Usually orange or lemon flavored, liquid fish oil may be a faint fishy taste and odor, but usually not as prominent as the capsules. There's also less stomach upset.
--Coromega--a paste form of fish oil available at health food stores or through http://www.coromega.com. Coromega tastes fruity and comes in little squeeze envelopes.
--Frutol--Pharmax, a British company, makes another fruity fish oil that is non-oily and tastes like apricot. It's actually fairly reasonably priced, too. However, it is hard to find. The only way I know to get is to go online at www.pharmaxllc.com. You may have to actually order through a health care provider.

When using any preparation of fish oil, the best way to determine your dose is to add up the EPA and DHA content. For instance, if you use a fish oil liquid that contains 320 mg EPA and 240 mg DHA per teaspoon, you will need two teaspoons a day to achieve the equivalent of our starting dose of 1200 mg of EPA+DHA, usually provided by 4000 mg total in 4 capsules. Note that some lipid and lipoprotein disorders will require higher doses, e.g., 1800 mg EPA+DHA for high triglycerides (>200 mg/dl) or high IDL.

Sudden death in athletes

A recent report in the Journal of the American Medical Association details how a group in the Veneto region of Italy cut back on the incidence of sudden cardiac death in athletes by a simple screening program.



You can read the abstract of the article at http://jama.ama-assn.org/cgi/content/full/296/13/1593.

Although sudden death in athletes is still a rare event, it is especially tragic when it happens. In this population, the incidence was 3.6 deaths per 100,000 athletes aged 12 to 35 years. By implementing a simple screening program that involved only a physical examination and an EKG, an astounding 89% reduction in sudden death was documented.

What lessons does this hold for those of us interested in coronary plaque reversal? Beyond the obvious lesson of pointing out the great benefit of simple screening of athletes, I believe that it tells us the value of simple screening tools for heart disease in general. It is my strong belief that, if we were to implement CT heart scans among the broad population of men 40 years and over, women 50 years and over--without regard to cholesterol or other relatively lame risk identifiers--we could slash the risk for heart attack and death 90% or more. Putting CT heart scans into the hands of the public makes your coronary risk obvious. It takes the guesswork out of risk predictors like cholesterol and high blood pressure.

But heart scans are already available, you say! Yes, of course they are. But the lack of insurance reimbursement continues to be a restricting factor for many people, despite the number of lives that could be potentially saved and the money that would be saved in the long run by reducing need for major heart procedures. The continuing resistance to prevention by my cardiology colleagues and the persistent ignorance of primary care physicians also remain major impediments.

But it's getting better. You don't have to be chained by ignorance. Put your CT heart scan to good use.

My heart scan was wrong!



Tom came into the office ready for a confrontation.

Tom's wife insisted that he see me to discuss the implications of his CT heart scan score of 459. At age 50, this was clearly bad news that placed Tom in the 99th percentile (worst 1% of men in his age group).

But Tom had already undergone a stress test. There had apparently been a small abnormality, and a heart catheterization had been performed by another cardiologist. "They told me they didn't need to do anything. No stent, no ballon, no bypass, nothing!"

I asked, "Did they tell you that there was any plaque or blockages seen?"

"Yeah, but he said it was nothing. So the heart scan was wrong!"

I've been here many times before. I explained to Tom that, no, his heart scan was not wrong. All the tests he'd undergone siimply provided a different perspective on the same disease. You could say:

--The stress test, being a test of blood flow, may have been abnormal because of the abnormal constrictive behavior of arteries containing plaque, known as "endothelial dysfunction", because the inner lining of arteries (the endothelium) control the tone of the artery. Abnormal constriction in arteries with plaque is quite common.

--The catheterization simply showed that no plaque had collected in a configuration to block flow, thus no stent, etc., since flow was normal. But there was indeed plaque.

All three tests were right; none were wrong. They all provided a little different perspective on the same process. Of course, I favor the heart scan as the means to identify, precisely measure, and track the atherosclerotic plaque in your arteries. The stress test is too crude and only measures flow, the catheterization is not something you'd want to undergo year after year. Catheterization also is too crude a measure to precisely track plaque growth or reversal.

So I explained to Tom that, even though a stent or similar procedure was unnecessary, he remained at substantial risk for heart attack due to plaque "rupture". In fact, Tom's heart attack risk was 5% per year, or approximately 50% over the next decade. That is, indeed, substantial. In fact, you might say that, of the three tests Tom underwent, only the heart scan revealed his true risk.

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.


Wheat-free gummi bears:


Contents:
Organic dehydrated cane juice, organic corn malt syrup, organic juice concentrates (may contain organic apple, organic apricot, organic aronia, organic carrot, organic cranberry, organic elderberry, organic lemon or organic red beet), organic spinach powder, organic apple pectin, citric acid, natural fruit flavors.

Virtually pure sugar--yet wheat-free.



Wheat-free rice bread


Ingredients:
White rice flour, water, honey, soy oil, natural gum, salt, yeast, natural gum

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.
