A curious case of coronary plaque regression and progression

John received a coronary stent in 2003 following a small heart attack. The artery causing the heart attack was a diagonal artery, a branch of the important left anterior descending coronary artery (in the front of the heart). His cardiologist at the time advised him, "Take Lipitor and we'll do stress tests every year. Come back if you have any more chest pain." That was the full extent of John's preventive care.

He came to me for a second opinion and, naturally, we enrolled him in our program. We began by obtaining a CT heart scan score, though we had to exclude the stented diagonal artery. His score: 471. At age 51 and physically active, John had 7 additional abnormal lipoprotein patterns identified. We counseled John on better approaches to food choices, his weight target, fish oil, and correction of all lipoprotein patterns.

Two years later, John's repeat heart scan score: 511 . John was initially disappointed with the increase. But a closer look yielded something entirely different: the right coronary artery and circumflex (no stents) showed 20-30% reduction in their scores. The increase in total score was entirely due to substantial increase in score just outside the stent, in the left anterior descending artery. In other words, all of the increase in score was due to growth of a plaque at the mouth of the stent in the diagonal artery.

This is curious: profound regression of plaque with a big drop in score in the "un-instrumented" arteries, but tremendous growth of plaque and an increase in score in the "instrumented", or stented, artery, all in the same person's heart.

I don't know how controllable this specific situation in the left anterior descending and stented diagonal will be, and I'm unaware of any specific strategies to impact on this situation. The whole world of tissue growth within or around stents is littered with high hopes followed by failures. The drug-coated stents have been the only partial solution to this problem, though that's precisely the sort of stent John received.

Is there a message here? The message I take from this is that you and I should work like mad to keep from receiving a stent. Once they're implanted, we have less control over our coronary future. We can indeed regress ("reverse") coronary plaque. But we may not be able to regress the sort of tissue that grows in response to a stent implantation.

When is a heart scan score of 400 better than 200?

Imagine two people.

Tom is a 50-year old man. Tom's initial heart scan score is 500--a bad score that carries a 5% or more risk for heart attack per year.

Harry is also 50 years old. His heart scan score is 100--also a concerning score but not with the same dangers of Tom's much higher score.

Tom follows a powerful heart disease prevention program like the Track Your Plaque program. He achieves the 60:60:60 lipid targets; chooses healthy foods; takes fish oil; raises his blood vitamin D level to >50 ng/ml, etc. One year later, Tom's heart scan score is 400, a 20% reduction from his starting score.

Harry, on the other hand, doesn't understand the implications of his score. Neither does his doctor. He's casually provided a prescription for a cholesterol drug by his doctor but nothing else. One year later, Harry's heart scan score is 200, a doubling (100% increase) of the original score.

At this point, we're left with Tom having a score of 400, Harry with a score of 200. That is, Tom has twice the score, or 200 points higher, compared to Harry. Who's better off?

Tom is better off. Even though he has a significantly higher score, Tom's plaque is regressing. It is therefore quiescent with its components being extracted, inflammation subsiding, the artery is in a more relaxed state, etc.

Harry's plaque, in contrast, is active and growing: inflammatory cells are abundant and producing enzymes that degrade supportive tissue, excessive constrictive factors are constantly causing the artery to pinch partially closed, fatty materials are accumulating and triggering a cascade of abnormal responses.

This is therefore a peculiar situation in which a higher score is actually better than a lower score. It reflects the power of adhering to a preventive program. It also demonstrates how two scans are better than one because they show the rate of increase given a particular preventive approach.

Warning: Your cardiologist may be dangerous to your health!

Warren had a moderately high LDL cholesterol for years and took a statin drug sporadically over the past 7 years. Finally retired from a successful real estate investment business, he had a CT heart scan to assess his heart disease status.

Warren's score: 49. At age 59, this put him in the lowest 25%, with an estimated heart attack risk of 1% per year or less--a relatively low risk. At this heart scan score, the likelihood of an abnormal stress test was less than 3%, or a 97% likelihood of a normal stress test. Most would argue that a stress test would be unproductive, given its low probability of yielding useful information. In other words, there would be a 97% probability of normal blood flow through Warren's coronary plaque, and less than 3% likelihood that a stent or bypass surgery would be necessary.

Warren was also without symptoms. He hiked and biked without any chest discomfort or breathlessness. A prevention program like Track Your Plaque to gain control over future coronary plaque growth was all that was necessary and Warren had high hopes for a life free of heart attack and major heart procedures.

Then why did he go through a heart catheterization?

Warren did indeed undergo a heart catheterization on the advice of his cardiologist. When I met Warren for another opinion, it became immediately obvious that the heart catheterization was completely unnecessary. Then why was this invasive procedure done? There can only be a few reasons:

--The cardiologist didn't truly understand the meaning of the heart scan score. "We need to do a 'real' test."

--The cardiologist was terrified of malpractice risk for underdiagnosing or undertreating any condition, no matter how mild.

--The cardiologist wanted to make more money. Talking about heart disease prevention is a money-saving, not a money-making, approach.

Regardless of which of the three motivations was at work here, they're all inexcusable. A disservice was done to this man: he had an unnecessary procedure, incurred some risk of complication in the process, and gained nothing.

An ignorant or profit-seeking cardiologist is worse than the unscrupulous car mechanic who, when presented with an unknowing car repair customer, proceeds to replace the carburetor and rebuild the engine when a simple 5-minute adjustment would have taken care of the problem.

I estimate that no more than 10% of my colleagues follow such practices, but it's often hard to know who is in that 10%. Ask pointed questions: Why is the catheterization necessary? What is the likelihood of finding information useful to my health? What are the alternatives? (By the way, the emerging CT coronary angiograms can be a useful alternative in some situations like this.)

I don’t have high blood pressure!

Art undeniably had high blood pressure.

At age 53, he had all the “footprints” of high blood pressure that’d been present for at least several years: abnormal patterns by EKG, abnormally thick heart muscle, and an enlarged aorta by an echocardiogram. These sorts of changes require many years to develop. Art’s blood pressure was 140/85 sitting quietly in the office.

“That’s about what my primary care doc gets, too. Whenever it’s high, he takes it again after a few minutes and it always comes down.”

Art tried to persuade me that his blood pressure was high today only because of the traffic on the way into the office. When I dismissed this as a cause, he insisted that stress he’d been suffering because of his teenage son was the cause. “I just know I don’t have high blood pressure!”




Who’s right here? Well, Art is not here to defend himself. But one fact is crystal clear: you cannot develop complications of high blood pressure unless you truly have high blood pressure!

In other words, Art’s abnormal changes in heart structure (thickened heart muscle and enlarged aorta) are serious changes that develop only with years and years of sustained blood pressure at least as high as the one in the office. His blood pressure almost certainly ranged much higher at other times, particularly during stressful situations like waiting in the check-out line at the grocery store, watching a suspenseful TV show, petty irritations at his job, and on and on.

Blood pressure does not have to be high all the time to generate complications of high blood pressure. It can be sporadic, variable, even occasional. Clearly, sustained high blood pressure is the worst situation that creates adverse consequences more quickly. But blood pressure that wavers from low to high only some of the time can still, given sufficient time, cause the very same unwanted effects.

Control of blood pressure is crucial to your coronary plaque control program. Blood pressure may be boring: not as exotic, say, as lipoproteins, and not as fun as talking about nutritional supplements. But neglect blood pressure issues and you will not gain full control over coronary plaque growth—-your heart scan score will increase.

Watch for an upcoming Special Report on the Track Your Plaque Membership website, a full detailed discussion of how to recognize when blood pressure is an important issue, along with a full discussion of nutritional methods to reduce it, often sufficient to minimize or eliminate the need for medication.

Are there any alternatives to niacin?

In the Track Your Plaque program, we tend to rely a great deal on niacin. When used properly, 90-95% of people will do just fine and achieve their lipid and lipoprotein goals with the help of niacin, along with their other efforts.

Unfortunately, around 5% of people simply can't take niacin without intolerable "hot flush" effects, or occasionally excessive skin sensitivity--itching, burning, etc.

Why does this happen? These 5% tend to be "rapid metabolizers" of niacin, i.e. they convert niacin (nicotinic acid, or vitamin B3) into a metabolite called nicotinuric acid. Nicotinuric acid is the compound responsible for the skin flush. Most people can slow or reduce the effects of nicotinuric acid by:

--Taking niacin with dinner, so that food slow tablet dissolution.

--Taking with plenty of water. Two 8-12 oz glasses usually eliminates the flush entirely in most people.

--Taking with an uncoated 325 mg tablet of aspirin in the first few weeks or months. Eventually, you will need to revert back to a better stomach tolerated dose of 81 mg, preferably enteric coated. But a full 325 mg uncoated can really help in the beginning, or when you have any niacin dose increases, e.g., 500 mg to 1000 mg.

But even with these very effective strategies, some people still struggle. That's when the question arises: Are there any alternatives to niacin?

Well, it depends on why niacin is being used. If you and your doctor are using niacin for:

Raising HDL--Then weight loss to your ideal weight; reduction of processed carbohydrates, especially wheat products; avoidance of hydrogenated ("trans") fats; a glass or two of red wine per day; dark chocolates (make sure first ingredient is chocolate or cocoa, not sugar), 40 gm per day; fish oil; exercise; other prescription agents (fibrates like Tricor; TZD agents for diabetes; cilostazol (Pletal)). Niacin is by far the most effective agent of all, but, if you're intolerant, raising HDL is still possible through a multi-faceted effort.

Reduction of small LDL--The list of effective strategies is the same as for raising HDL, but add raw almonds (1/4-1/2 cup per day), oat bran and other beta-glucan rich foods like oatmeal. Reduction of processed carbohydrates is especially important to reduce small LDL.

Reduction of Lipoprotein(a)--This is a tricky one. For men, testosterone and DHEA are effective alternatives; for women, estrogen and perhaps DHEA. Hormonal preparations of testosterone and estrogen are stricly prescription; DHEA is OTC. I have not seen the outsized benefits on lipoprotein(a) claimed by Rath et al by using high-dose vitamin C, lysine, and profile, unfortunately. We are clearly in need of better alternatives to treat this difficult and high-risk disorder.

Reduction of triglycerides/VLDL/IDL--I lump these three together since they all respond together. If you're niacin intolerant, maximixing your fish oil can be crucial for reduction of these patterns using doses above the usual starting 4000 mg per day (providing 1200 mg EPA+DHA). Reduction of processed carbohydrates, eimination of processed foods that contain high-fructose corn syrup, and weight loss to ideal weight are also very effective. "Soft" strategies with modest effects include green tea (>6 cups per day) or theaflavin 600-900 mg/day; raw nuts like almonds, walnuts, and pecans; exercise; soy protein.

Reduction of LDL--Lots of alternatives here including oat bran (3 tbsp per day), ground flaxseed (3 tbsp per day), soy protein (25 grams per day), Benecol butter substitute (for stanol esters), soluble fibers like pectin, psyllium, glucomannan; raw nuts like almonds, walnuts, and pecans.

In future, should torcetrapib become available (by prescription), this will add to our available tools for these areas when niacin can't be used. Until now, the alternatives to niacin depend on what you and your doctor are trying to achieve. In the vast majority of cases, HDL, small LDL, triglyceride, etc. goals for heart scan score control can be achieved, even when niacin is not well tolerated.

Is flaxseed oil a substitute for fish oil?


This question comes up so frequently that it's worth going over.

Flaxseed oil is a wonderful oil rich in linolenic acid, which may provide health benefits all by itself. Some authorities have speculated that the substantial reduction in heart attack seen in the Lyon Heart Study, the study that demonstrated the healthy power of the Mediterranean diet, is due to linolenic acid.

Flaxseed oil is also rich in monounsaturates and low in saturates, both desirable qualities. Of course, I'm talking here about flaxseed oil, to be distinguished from flaxseed , which are the intact seeds. The seeds themselves also contain the same oils, but contain other components, specifically lignan, a plant fiber with suspected health benefits like reduction in cancer risk.

Despite all flaxseed oil's wonderful properties, it is definitely not a substitute for fish oil. Why do we use fish oil for our coronary plaque control program (trying to reduce your heart scan score)? Several reasons. Fish oil:

--Dramatically reduces triglycerides, usually by 50% or more.
--Dramatically reduces specific lipoprotein classes like VLDL
--Dramatatically reduces, often eliminates, abnormal postprandial (after-eating) lipoprotein patterns, like IDL (intermediate-density lipoprotein)
--Has been conclusively shown to reduce risk of heart attack and death from heart attack (GISSI Prevenzione Trial).
--Has been shwon to reduce risk of stroke.
--Modifies blood clotting parameters, particularly a 20% reduction in fibrinogen.

Flaxseed oil, or linolenic acid concentrate for that matter, do not accomplish any of these effects, all crucial if you are to gain control over your coronary plaque.

Flaxseed oil and flaxseed remain wonderful nutritional agents for their own reasons. But they will not substitute for fish oil in your program. Only fish oil--the real thing--does the job.

If you have coronary artery disease . . . do you know why?

This conversation is aimed primarily at non-followers of the Track Your Plaque program, because if you were a follower, you’d already know the answer!

I saw a woman in the hospital today. She’d just survived her second heart attack one week earlier. At 51 years old, she was understandably shaken, perhaps terrified. She felt that her future was uncertain and, in fact, had discussed with her husband what he should do to prepare for a future without her.

One week earlier, she’d received three stents that successfully aborted her heart attack. But, as is always the case, the modest delays of ambulance transport, the emergency room preliminaries, then of mobilizing an available cardiologist and catheterization laboratory team, totaled nearly two hours before her stent procedure. Inevitably, a moderate amount of damage had been done to her heart.

Her first “event” had been very similar: very little warning, then 911 and the flurry of activity. Both times, the cardiologists (two different physicians) complimented the patient on her prompt action. Both also called her heart attacks “close calls”.

She defied the odds with two near-death events. So, when I met her a week after her last heart attack, I asked an obvious question: “Has anyone told you why you’re having these heart attacks?”

She looked completely puzzled at first. She then said, “No, not really. I just assumed it was genetic. My mother went through the same thing when she was my age. But she didn’t get as far as I have, since they didn’t have these procedures back then.”

To me, this seems inexcusable: This woman had experienced two brushes with death and no doctor had established a cause. Could this woman’s belief be true, that it’s just genetic?

While there are, indeed, genetic causes for heart disease, the vast majority of these genetic causes are 1) identifiable, and 2) correctable. Genetic does not necessarily mean hopeless. It just means that the usual equation of heart disease risk management (heart disease = LDL cholesterol = need for Lipitor) has limited value. It would be like giving penicillin to people for any and all infections. It will work occasionally, but it will fail miserably in a great many cases. Treating LDL cholesterol with statin drugs is just like that.

Perhaps this woman has lipoprotein(a), a serious genetic trait that predicts heart disease at a young age and is largely unaffected by statin drugs. Or, she may have a severe excess of small LDL, only partially suppressed by statins. If she has the combined pattern of lipoprotein(a) and small LDL, that means she has two statin-unresponsive and significant genetic traits. But they respond to niacin, specific nutritional strategies, and several other agents.

The message: If you have coronary disease, you need to insist on knowing why. “It’s genetic” is not an acceptable answer. “There’s no proof of any heart disease causes beyond cholesterol” is also nonsense. “Everyone gets heart disease, or “hardening of the arteries”, eventually. You just got it a little before everyone else” is also patently ridiculous.

Identifying the causes of your coronary disease (or coronary plaque if you’ve had a CT heart scan) is the first step in developing a program of treatment that provides you with control over this disease.

Have you tried inulin yet?

If you haven't yet tried it to facilitate weight loss, it's really worth giving the new inulin-containing product, Fiber Choice "Weight Management", a try.

Recall (from a prior Heart Scan Blog) that inulin is a vegetable-based fiber found in celery, green peppers, etc. that, when exposed to water, expands to many times original volume. This simple phenomenon yields satiety--a feeling of fullness.


The manufacturer of the product has also added green tea, which has been shown in two small clinical studies to enhance weight loss, though by a different route.

We've been advising patients to chew two of the strawberry flavored tablets one hour before every meal (or with breakfast if you eat immediately in the morning). You'll be satisfied with less food and you'll experience less intense food cravings.

Though no one so far has achieved a huge drop in weight, it does seem to enhance a slow, gradual weight loss larger than achieved by diet and exercise alone. And it's very safe and inexpensive. If you give it a try to help you lose weight, let us know what kind of results you've obtained.

More on Vitamin D

If you haven't done so already, you should subscribe to Dr. John Cannell's free newsletter on vitamin D issues. His newest issue is available at:

http://www.vitamindcouncil.com/newsletter/2006-aug.shtml

A sign-up to subscribe is available on the same page.

I continue to be shocked and amazed at the prevalence and magnitude of vitamin D deficiency in the people I see every day. It's been a beautiful summer with very little rain. Most days have been in the 70-80 degree range--very comfortable to be outdoors in the sun and getting skin expoxure to activate vitamin D in the skin.

Yet, in the vast majority of people I see, summer blood levels of vitamin D are virtually indistinguishable from winter levels. Both hover around the 30 ng/ml range. Summer levels in Wisconsin people seem to be no more than 10 ng/ml higher than winter levels. This remains true even in people who spend a lot of their day outdoors gardening, walking, etc. wearing shorts and a short-sleeved shirt, i.e. with plenty of skin surface area exposed.

I'm at a loss to explain precisely why. Yes, it is Wisconsin. But a direct sun overhead, 75 degree day should be providing plenty of sun. My suspicious is that a combination of factors are at work: people are not spending as much time outdoors as they claim; they often seek shade; use sunscreen; and they're overweight. (Excess weight decreases vitamin D blood levels dramatically, yet another reason not to get fat!)

Read more about vitamin D by checking out Dr. Cannell's insightful comments on the unfolding vitamin D story. He holds nothing back.

Heart attack guaranteed

What if you knew for a fact that your risk for heart attack was 100% by, say, age 58? This is indeed true for many people, though at age 60, 65, 70--or 45.

In other words, unless something were done about the causes of heart disease, you would inevitably suffer a heart attack at 58.

What sort of action could you take at age 45?

Obviously, not smoking is an absolute requirement. Continue and you may as well start getting your affairs together.

How about exercising and eating a generally healthy diet? Will your risk be reduced to zero? No. It might be reduced 20-30%, depending on genetic factors.

How about a statin drug? Watch TV ads during Oprah, and you might think it's a cure. But in reality, while it is a financial bonanza for the drug manufacturers, it will reduce risk for heart attack by 30%.

(Note that risk reduction by following multiple strategies is not necessarily additive. In other words, if you have a healthy lifestyle and take a statin agent, is risk reduced 60% (30 + 30)? No, because the effects may overlap.)

So, eating healthy, exercising, and taking a statin drug might reduce risk 35-40%, maybe 50% in the best case scenario. Would you be satisfied? Most would not.

Add fish oil at a truly therapeutic dose. Risk reduction by itself: 28%.

Add niacin or other strategies for correction of your individual, specific causes of heart disease: Now we're up to 90% reduction.

Throw in a tracking process to prove whether or not atherosclerotic plaque has progressed or reversed. Now we're approaching 100% if plaque reverses. The only way I know how to track plaque is through CT heart scans. What other test is readily available to you with low radiation exposure, yet is relatively inexpensive and precise? It certainly is not stress testing, heart catheterization, CT angiograms, or other techniques. Cholesterol won't tell you. Besides CT heart scans, there's nothing else I know of.

Let's fact it: For many people, uncorrected risk for heart attack is truly 100% at some age. Take action while you can.

That, in a nutshell, is the Track Your Plaque program.

Heart scan curiosities 3



This is a sample image from the heart scan of a 54-year old, 212 lb, 5 ft 2 inch woman. The heart is the whitish-gray in the center; lungs are the dark (air-filled) areas on either side of the heart. Note the massive amount of surrounding gray tissues that encircles the heart and lungs. This is fat. At this weight, the diameter of total fat exceeds the combined diameter of the heart and lungs. If we were to show the abdomen, there would be even more fat. (The image shows the body not well centered because the technologist centers the heart, since this is, after all, a heart scan.)





This is a 55-year old, 151 lb, 5 ft 4 inch woman. Note the contrast in the quantity of fat tissue surrounding the chest, a much more normal appearance. Note that this woman is still around 25 lb over ideal weight, but not to the extreme degree of the woman above.

Another curious observation: Note the more whitish streaking in the heavier woman's lungs. Heart scans are performed while holding a deep inspiration (a deep breath inwards), mostly to eliminate lung respiratory motion during image acquisition. Nonetheless, the heavier woman's lungs are not as fully expanded as the more slender woman. In other words, the heavier woman cannot inflate her lungs as effectively as the thinner woman. Ever notice how breathless heavy people are? Some of this effect is just being out of shape. But there's also the added effect of the abdominal fat exerting upwards compression on the lung tissues, and the constrictive effect of the encircling fat mass. At the beginning of inspiration, the chest fat exerts the resistance of inertia to inspiration that is absent, or less, in a slender person. With each breath, the heavy woman must move 50 lbs or so of surrounding fat mass just to inhale.

The heavier woman is, in effect, suffocating herself in fat.

The distortions to the human body incurred by extreme weight gain are both fascinating and shocking. I hope you're breathing easily.

The shameful "standard of care"

John's initial heart scan four years ago showed a score of 329. His physician prescribed Zocor for a somewhat high LDL cholesterol.

One year later, John asked for another scan. His score: 385, a 17% increase. John exercised harder and cut his fat intake.

This past fall--3 years after his last scan--John had yet another heart scan. Score: 641, a 66% increase over the last scan, all the while on Zocor.

John sought an opinion from a reputable cardiologist. He concurred with the prescription of Zocor and advised annual stress tests. That's it.

Followers of the Track Your Plaque approach know that the expected uncorrected rate of increase in heart scan score is 30% per year. On Zocor or other cholesterol reducing statin agent, a common rate of growth is between 18-24% per year--better but not great. Plaque growth is certainly not stopped.

But that is the full extent of interest and responsibility of your cardiologist. Prescribe a statin drug, perform a stress test, and the full extent of his obligation has been fulfilled. In legal terms, your physician has met the prevailing
"standard of care". No more, no less.

In other words, the prevailing standard of care falls shamefully short of what is truly possible. For the majority of the motivated and interested, coronary plaque reversal--reduction of your heart scan score--should be the standard aimed for. It's not always achievable, but it is so vastly superior to the prescribe statin, wait for heart attack approach endorsed by most cardiologists.

Heart scan curiosities 2



This is an example of a so-called "hiatal hernia", meaning the stomach has migrated through the diaphragmatic hiatus into the chest--the stomach is literally in the chest. This example is an unusually large one. Hiatal hernias can cause chest pain, indigestion, and a variety of other gastrointestinal complaints. Heart scans are reasonably useful to screen for this disorder, though very small ones could escape detection by this method.

Sometimes, you can actually hear the gurgling of stomach contents (the common "growling" stomach) by listening to the chest. Large ones like this actually crowd your heart (the gray structure above the circled hernia), irritating it and even causing abnormal rhythm disorders. The dense dark material within the hernia represents lunch.

I would not advocate CT heart scans as a principal method to make a diagnosis, but sometimes it just pops up during a heart scan and we pass it on to the person scanned.

Vitamin D: New Miracle Drug

At the meetings of the American Society of Bone and Mineral Research, Dr. Bruce Troen of the University of Miami detailed his views on the extraordinary benefits of vitamin D replacement. He also talked about the enormous problem of unrecognized vitamin deficiency.

“There’s a huge epidemic of hypovitaminosis D, and the real key here is not just that it’ll benefit you from a bone and neuromuscular standpoint, but if you correct hypovitaminosis D and the corresponding secondary hyperparathyroidism, then you’re going to decrease prostate cancer, colon cancer—actually “up to 17 different cancers, breast cancer included.”

Unfortunately, Dr. Troen did not talk much about the heart benefits of vitamin D, likely since the data is scant, nearly non-existent. However, if the Track Your Plaque experience means anything, I predict that vitamin D replacement will become among the most powerful tools you can use to gain control over coronary plaque.

Read the text of a report from the Internal Medicine World Report to read more of Dr. Troen's comments.

Heart disease "reversal" by stress test


Here's an interesting example of a 71-year old man who achieved "reversal" of an abnormality by a nuclear stress test.

This man underwent bypass surgery around 10 years ago, two stents three years ago. A nuclear stress test in April, 2005 showed an area of poor blood flow in the front of the heart. On the images, normal blood flow is shown by the yellow/orange areas. poor or absent blood flow is shown by the blue/purple areas within the white outline.

Now, I can tell you that this man is no paragon of health. He's only accepted limited changes in his otherwise conventional program--in other words, someone who I'd be shocked achieved true reversal of his heart disease. (I didn't have him undergo any CT heart scans because of the difficulties in scoring someone who has undergone bypass surgery and stents, and because of limited motivation. True plaque reversal is for the motivated.)This patient did, however, accept adding fish oil and niacin to his program.

Nonetheless, stress testing can be helpful as a "safety check". Here's the follow-up stress test:
You'll notice that the blue/purple areas of poor blood flow have just about disappeared. This occurred without procedures.

Does this represent "reversal"? No, it does not. It does represent reversal of this phenomenon of poor flow. It does not represent reversal of the plaque lining the artery wall. That's because improvement of flow, as in this man, can be achieved with relatively easy efforts, e.g., improvement in diet, statin drugs, blood pressure control, etc. True reversal or reduction of coronary plaque, however, is tougher.

If blood flow is improved, who cares whether plaque shrinks? Does it still matter? It does. That's because the "event" that gets us in trouble is not progressive reduction in blood flow, but "rupture" of a plaque. A reduction in plaque--genuine reversal--is what slashes risk of plaque rupture.

Calcium reflects total plaque





People frequently ask, "Why measure coronary artery calcium? My doctor said that calcium only tells you if there's hard plaque, and that hard plaque is stable. He/she says that calcium doesn't tell you anything about soft plaque."

Is that true? Is calcium only a reflection of "hard" plaque? Is hard plaque also more stable, less prone to rupture and causes heart attack?

Actually, calcium is a means of measuring total plaque, both soft and hard. That's because calcium comprises 20% of total plaque volume. Within plaque, there may be areas that are soft (labeled "lipid pool" in the diagram). There are also areas made of calcium (shown in white arcs within the plaque). Even though this is just a graphic, it's representative of what is seen when we perform intracoronary ultrasound of a live human being's coronary artery. In other words, this cross section contains both "soft" (lipid pool) as well as "hard" (calcium) elements.

Is this artery "soft" or "hard"? It's both, of course. The artery compostion can vary millimeter by millimeter, having more soft or hard elements. The artery can also change over time in either direction. Thus, "soft" plaque may indeed be soft today, only to be "hard" in 6 months, and vice versa.

The essential point is that measuring just "soft" plaque provides limited information. What the CT heart scan does is provide a gauge of total plaque, soft and hard, and it does so easily, safely, precisely. If your score increases, the lengthwise volume of total plaque has also grown. If your score decreases, the total amount of plaque has also decreased.

Don't mistake marketing for truth

We're all so inundated with marketing messages for food. Unfortunately, many people confuse the messages delivered through marketing with the truth.

For instance:

Pork: "The other white meat." Pork is a high-saturated fat food.

"Bananas: A great source of potassium." Bananas are a high glycemic index (rapid sugar release), low fiber food.

"Pretzels: A low-fat snack." A high glycemic index food made from white wheat flour. It makes you fat and skyrockets blood sugar.

Jif peanut butter: "Choosy moms choose Jif." Do they also choose hydrogenated fats?

Hi-C: Upbeat jingles like "Who put the straw in my Hi-C fruit drink, a new cool straw that wriggles and bends? Who put the straw in my Hi-C fruit drink, with Vitamin C for me and my friends? Who was that man, I'd like to shake his hand, he made my Hi-C cooler than before!" What about the 25 grams of sugar per 4 oz serving? And the high fructose corn syrup that creates an insatiable sweet tooth, raises triglycrides 30%, and exagerates pre-diabetes?


Marketing is not reliable, unbiased information. If Ford boasts that their cars are superior to GM, do you say "Well then, I need to buy a Ford?" Of course not. Take marketing for what it is: A method of persuading people to buy. It may or may not contain the truth. It's a big part of the reason Americans are the fattest people on earth and are experiencing an explosion of chronic diseases of excess.

Tattered Red Dress

"Are you taking your health to heart? Perhaps you understand the importance of eating a diet low in cholesterol or getting 30 minutes of exercise a day. But do you know your own risk of developing cardiovascular disease?


It’s time to take your heart health personally. Heart disease is the No. 1 killer of American women — and that means it is not “someone else’s problem.” As a woman, it’s your problem.

That’s where the Go Red Heart Checkup comes in. This comprehensive evaluation of your overall heart health can help you now and in the future. By knowing your numbers and assessing your risks now, you can work with your doctor to significantly reduce your chances of getting heart disease tomorrow, next year, or 30 years from now!"



So reads some of the materials promoted by the American Heart Association Red Dress campaign to increase awareness of heart disease in women. The effort is well-intended. There is no doubt that most women are unaware of just how common coronary disease is in females.

But I've got a problem with the solutions offered. "Know your numbers"? Eat healthy, don't be overweight, be active, don't smoke. That's the gist of the program's message--nothing new. In 2006, why would some sort of screening effort for detectin of heart disease not be part of the message? Why isn't there any message about the real, truly effective means to detect hidden heart disease in women--namely, heart scanning?

Does a 58-year old woman with normal blood pressure, LDL 144, HDL 51, 20 lbs overweight have hidden heart disease? I've said it before and I'll say it again: You can't tell from the numbers. She could die of a heart attack tomorrow without warning, or maybe she'll be dancing on our graves when she's 95 and never have experienced any manifestation of heart disease. The numbers will not tell you this.

I'm glad the American Heart Association has seen fit to invest its sponsors' money in a campaign to promote prevention. I wish they hadn't fallen so far short of a truly helpful message. Perhaps the sponsors (like Pfizer, maker of Lipitor) will benefit, anyway.

Panic in the streets

Several days ago, I wrote about a local prominent judge in my neighborhood who was unexpectedly found dead in bed of a heart attack at age 49.

As expected, I've received multiple calls from patients and physicians who want heart catheterizations. For instance, an internist I know called me in a panic. He asked that I perform a heart catheterization in a patient with a heart scan score of 768. I've been seeing this patient for about a year. He's without symptoms, even with strenuous exercise; stress tests (i.e., tests of coronary bloow flow) have been normal.

I remind patients and colleagues every day, day in day out: Having a heart scan score revealing some measure of coronary plaque is not a sufficient reason by itself to proceed with procedures. Fear of suffering a fate like the unfortunate judge is also not a reason to proceed with procedures.

Increased awareness of the gravity of heart disease is a good thing. Some good can come out of a needless tragedy like this. The lesson from the judge's unfortunate experience: he needed a CT heart scan. I'm told that the judge's doctor advised him that a heart scan was a waste of time. I hope that appropriate legal action for negligence is taken by the judge's family against this physician.

Not doing a heart scan is wrong. That's the lesson to learn. The lesson is not that everybody with coronary plaque needs a procedure. Had the judge undergone a simple heart scan, intensified prevention could have been instituted and he'd still be alive with his wife and children today.

The indications for procedures are unchanged by your heart scan. If a stress test is abnormal and indicates poor flow to a part of the heart, that would be a reason. If symptoms like chest discomfort or breathlessness appear, that's an indication. If there's evidence of poor heart muscle contraction, that's a reason to proceed with a procedure. But just having coronary plaque is not a sufficient reason.

Dr. Reinhold Vieth on vitamin D

A Track Your Plaque member brough the following webcast to our attention:

Prospects for Vitamin D Nutrition
which can be found at http://tinyurl.com/f93vl

Despite the painfully dull title, the webcast is the best summary of data on the health benefits on vitamin D that I've seen. The presenter is Dr. Reinhold Vieth, who is among the handful of worldwide authorities on vitamin D. In 1999, Dr. Vieth authored the first review to concisely and persuasively argue that vitamin D nutrition was woefully neglected and that its potential for health was enormous.
(See Vieth R, Am J Clin Nutr 1999 May;69(5):842-856 at http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=AbstractPlus&list_uids=10232622&query_hl=1&itool=pubmed_DocSum.)

I predict that, after viewing Dr. Vieth's hour-long discussion, you will be as convinced as I am that vitamin D is crucial for health. Unfortunately, Dr. Vieth doesn't delve into the conversation about the potential effects on heart disease, since his audience was primary interested in multiple sclerosis, a disease for which vitamin D replacement promises to have enormous possibilities. Even in 2007, the data suggesting that vitamin D has heart benefits is circumstantial. Nonetheless, from our experience, I am thoroughly convinced that, with replacement to blood levels of vitamin D to 50 ng/ml, heart scan scores drop more readily and faster.

If you view Dr. Vieth's wonderful webcast, keep in mind that when he discusses vitamin D blood levels, he's using units of nmol/l, rather than ng/ml. To convert nmol/l to ng/ml, divided by 2.5. For example, 125 nmol/l is the same as 50 ng/ml (125/2.5 = 50).

Vitamin D on Good Morning America


Positive comments about vitamin D made it to a discussion on Good Morning America today about the new and exciting developments in nutrition and "functional foods".

I'm thrilled that the media is conducting these conversations. It sure is making my job easier, not having to persuade patients that taking vitamin D is truly and hugely beneficial for health. I still have to struggle with my colleagues, who tell patients to stop the "poisonous" doses we use.

But I worry that many of the details behind vitamin D don't quite make it to the media conversation. These are crucial, make-it-or-break-it issues, such as:

--Vitamin D must be vitamin D3 or cholecalciferol, not D2 or ergocalciferol. D2 is virtually worthless. Little or none is converted to the active D3, despite the fact that D2 is the form often added to some foods.

--Vitamin D3 supplements must be oil-based capsules, or gelcaps. Tablets are so poorly or erratically absorbed that it's simply not worth the effort. (We get ours from the Vitamin Shoppe.)

--The dose should be sufficient to eliminate the phenemena of deficiency, which is around 50 ng/ml. I take 6000 units per day. Dr. John Cannell of www.vitamindcouncil.com takes 5000 units per day. I give my wife 2000 units per day (she's not as deficient as I was), each of my kids 1000 units per day, except for my 180 lb. 15 year old who takes 2000 units.

I fear that, when people hear that vitamin D packs fabulous effects for health, they will take a 400 unit tablet--nothing will happen. They will not obtain the benefits such as reduction of blood pressure and blood sugar; increased bone density, reduction of arthritis, dramatic reduction in risk for fractures; reduction in risk for colon, prostate, and breast cancer; reduction in risk for multiple sclerosis; reduction in inflammatory processes such as those evidenced by C-reactive protein; and facilitation of reduction of heart scan score.

Would you bet your life on chelation?


Hugh's heart scan score was 1751, an awful score. Recall that, at this level of scoring, Hugh's heart attack and death risk is 25% per year.

Obviously, serious efforts need to be taken. In this situation, much as I despise drug companies and what they represent and their heavy-handed ways, I'm more inclined to resort directly to prescription agents, as well as our nutritional supplements and other strategies. The price of dilly-dallying could be his death.

Hugh and his wife asked about chelation. Now, there are five studies I'm aware of that have tried to examine the value of chelation. None showed any measurable benefit, though all were rather weak in design and small in number of participants. One study, for instance, looked at whether anginal chest pains were provoked any later after chelation. Another looked at whether calf claudication, or calf cramping while walking due to artery blockages in the leg arteries, was delayed on treadmill testing after chelation. No benefit was observed: no delay in provocation of angina, no delay in provocation of claudication.

However, the adherents of chelation have been vehement enough that the NIH has funded a large, multi-center study to settle the question once and for all. Best I can tell, the study has not been contaminated by any drug company involvement. It is meant to be an unbiased, objective study of whether chelation has any value.

My personal experience in patients who underwent chelation is that, despite spending hundreds or thousands of dollars, plaque grew at the expected rate--no effect at all.

None of this constitutes proof of efficacy nor proof of lack of efficacy. We will need to await the NIH trial to have better information.

Should Hugh bet his life on chelation? I advised him strongly against it. At this point, the only reason I can see to pursue chelation would be faith--that is, expectation based not on fact, but on hope.

The powerful forces preserving the status quo


An interesting quote from the book, Critical Condition: How health care in American became big business--and bad medicine:


Politics and Profits

To protect its interests and expand its influence, the health care industrial complex has done what all successful special interests do: It's become a big donor and a high-powered lobby in Washington. In the last fifteen years, HMOs, insurers, pharmacuetical companies, hospital corporations, physicians, and other segments of the industry contributed $479 million to political campaigns--more than the energy industry ($315 million), commercial banks ($133 million), and big tobacco ($52 million). More telling is how much the health care industry spends on lobbying. It invests more than any other industry except one, according to the nonpartiisan Center for Responsive Politics. From 1997 to 2000, the most recent year for which complete data is available, the industry spent $734 million lobbying Congress and the executive branch. Only the finance, insurance, and real estate lobby exceeded that amount in the same period, with a ttoal of $823 million. In contrast, the defense industry spent $211 million--less than one-third of the health care expenditure.


These telling statistics indicate just how vigorously profit-seeking forces in heart care are trying to preserve the status quo. Hospitals want to protect their valuable procedure-driven enterprise, the pharmaceutical industry wants to protect its enormous though little-known niche of procedure-based medications (like $1200 a dose ReoPro), and the medical device industry wants to maintain the multi-billion dollar-generating machine aided and abetted by the FDA's 501k rule (that makes entry to market a breeze).

The current procedure based formula for heart disease profits so many and they are desperate to preserve it. Resistance to the deep-pocketed efforts of industry and hospitals will come from people like you and me, trying to propagate a better way.

Remember: hospital procedures for coronary disease represent the failure of prevention. They are not--any longer--successes in and of themselves.

Read a scathing insight into some of these practices by reading investigative journalists' Donald Barlett and James Steele's book, Critical Condition. I found their descriptions painfully accurate. (But don't get too angry! Remember: only optimists reverse their plaque! We need to turn the conversation in a positive direction, not just in this Blog or the Track Your Plaque website, but nationwide.)

One of the new missions for the www.cureality.com website is to help you understand just how powerful, insidious, shrewd, and pervasive the efforts to maintain the current system truly are.

Do stents prevent reversal?

I've seen this phenomenon several times now: A highly-motivated Track Your Plaque participant with a stent in one artery will do all the right things--lose weight, achieve 60:60:60 in basic lipids, identify and correct hidden lipoprotein disorders, take fish oil, correct vitamin D, etc.

Follow-up heart scan shows dramatic reduction in scoring in the two arteries without stents--30% per artery. But the artery with the stent will show marked increase in scoring above and/or below the stent. (It's impossible to tell what happens in or around the stent itself from a calcium scoring standpoint, since steel looks just like calcium on a CT heart scan.) In other words, there is marked plaque growth in the vicinity of the stent, despite the fact that dramatic reversal of atherosclerosis has occurred in other arteries without stents.

Should we take this to mean that a stent destroys the opportunity for atherosclerotic plaque reversal in the stented artery? I don't know, but I fear this may be true. What dangers does this different sort of plaque pose? Is it the result of the injury imposed at time of stent implantation, some modification of flow or biologic responses as a result of the presence of the stent?

These are all unanswered questions. But I believe that it is yet another suggestive piece of evidence that the best stent is no stent at all.

At what score should I have a heart cath?

This question comes up frequently: At what specific heart scan score should a heart catheterization be performed? In other words, is there a specific cut-off that automatically triggers a need for catheterization?

In my view, there is no such score. We can't say, for instance, that everybody with a score above 1000 should have a catheterization. It is true that the higher your score, the greater the likelihood of a plaque blocking flow. A score of 1000 carries an approximately 25-30% likelihood of reduced blood flow sufficient to consider a stent or bypass. This can nearly always be settled with a stress test. Recall that, despite their pitfalls for uncovering hidden heart disease in the first place, stress tests are useful as gauges of coronary blood flow.

But even a score of 1000 carries a 70-75% likelihood that a procedure will not be necesary. This is too high to justify doing heart catheterizations willy-nilly.

Unfortunately, some my colleagues will say that any heart scan score justifies a heart cath. I believe this is absolutely, unquestionably, and inexcusably wrong. More often than not, this attitude is borne out of ignorance, laziness, or a desire for profit.

Does every lump or bump justify surgery, radiation, and chemotherapy on the chance it could represent cancer? Of course not. There is indeed a time and place for these things, but judgment is involved.

In my view, no heart scan score should autmatically prompt a major heart procedure like heart catheterization in a person without symptoms.

Niacin makes NY Times

In the wake of the crash and burn of Pfizer's torcetrapib, media attention has turned up the miracles of . . .good old niacin. The NY Times carried a well-written report on niacin in its recent report, An Old Cholesterol Remedy Is New Again.


(Read the entire report at http://www.nytimes.com/2007/01/23/health/23consume.html?em&ex=1169701200&en=670fa84ae2ea648c&ei=5087%0A)

Among their comments:

...torcetrapib worked primarily by increasing HDL, or good cholesterol. Among other functions, HDL carries dangerous forms of cholesterol from artery walls to the liver for excretion. The process, called reverse cholesterol transport, is thought to be crucial to preventing clogged arteries.

Many scientists still believe that a statin combined with a drug that raises HDL would mark a significant advance in the treatment of heart disease. But for patients now at high risk of heart attack or stroke, the news is better than it sounds. An effective HDL booster already exists.

It is niacin, the ordinary B vitamin.

In its therapeutic form, nicotinic acid, niacin can increase HDL as much as 35 percent when taken in high doses, usually about 2,000 milligrams per day. It also lowers LDL, though not as sharply as statins do, and it has been shown to reduce serum levels of artery-clogging triglycerides as much as 50 percent. Its principal side effect is an irritating flush caused by the vitamin’s dilation of blood vessels.

Despite its effectiveness, niacin has been the ugly duckling of heart medications, an old remedy that few scientists cared to examine. But that seems likely to change.

“There’s a great unfilled need for something that raises HDL,” said Dr. Steven E. Nissen, a cardiologist at the Cleveland Clinic and president of the American College of Cardiology. “Right now, in the wake of the failure of torcetrapib, niacin is really it. Nothing else available is that effective.”

In 1975, long before statins, a landmark study of 8,341 men who had suffered heart attacks found that niacin was the only treatment among five tested that prevented second heart attacks. Compared with men on placebos, those on niacin had a 26 percent reduction in heart attacks and a 27 percent reduction in strokes. Fifteen years later, the mortality rate among the men on niacin was 11 percent lower than among those who had received placebos.

'Here you have a drug that was about as effective as the early statins, and it just never caught on,' said Dr. B. Greg Brown, professor of medicine at the University of Washington in Seattle. 'It’s a mystery to me. But if you’re a drug company, I guess you can’t make money on a vitamin.'



Of course, you and I don't have to wait for the media to endorse something. I'm nonetheless thrilled that this hugely helpful vitamin is gaining greater recognition. My preferred form nowadays is over-the-counter SloNiacin (Upsher Smith). Weve seen no liver side-effects and a minimal quantity of flushing. It's also reasonably priced, $13.99 for 100 tablets of 500 mg at Walgreen's. That's a lot cheaper than prescription Niaspan at $130 for 60 tablets.

Perhaps the notoriety will cut back on the silly responses from some physicians that I still hear about from patients: "My doctor said to stop the niacin because it's going to destroy my liver."

Wheat: the nicotine of food

Yes, we know that wheat contributes to creating small LDL, drops HDL, raises triglycerides, and VLDL. We also know it indirectly slows the clearance of after-eating fats from the blood (curious, I know). Wheat products also increase inflammation (C-reactive protein), raise blood sugar, and contribute tremendously to diabetes.

What many people don't know is that wheat products also have an addictive quality: have one donut and you want another. It's true for bread, breakfast cereals, pretzels, cookies, etc. How many times have you had just one Oreo cookie?

Curiously, elimination of wheat products, unlike elimination of nicotine, usually causes the cravings to disappear. In other words, if you stop smoking cigarettes, the desire to smoke doesn't go away. With wheat products, the often overwhelming desire for more wheat products often just goes away.

But most people are simply unable to dramatically reduce or eliminate wheat products from their daily diet and therefore struggle each and every day with excessive cravings for bagels, donuts, cookies, breads, etc.

Try this useful experiment: Eliminate wheat products for a month and see what happens. Most people drop blood pressure, lose the tummy excess, feel more alert, see a drop in blood sugar, experience improvements in lipoproteins, and regain control over appetite.

Good time for a heart attack?

Man Has Heart Attack At Right Place, Right Time

If Robert Ricard had picked the wrong restaurant for lunch, he might have died.

The 71-year-old Michigan man suffered a heart attack shortly after ordering a glass of wine with friends at Bentley's Roadhouse on Saturday.

Luckily, a disaster medical team was sitting nearby.



A TV station in Michigan reported the above story. You've heard these "if it wasn't for ___, so and so would have died" stories. They're reported in all cities at one time or another.

What amazes me about these common local stories is that they're accepted at all. The question that comes to my mind is "Why couldn't the heart attack have been averted in the first place?" Early identification then, as close as humanly possible, elimination of risk would have been a preferable path.

Of course, it may not be the role of the media to cast judgement on why and how the entire episode could have been completely prevented from occurring. But you shouldn't fall into the same trap of complacency. We cannot expect others to save us when the "big one" hits. Your best assurance is to never have one in the first place.

How good is the South Beach Diet?

I'm a fan of the South Beach Diet.

Though it is billed as a program for weight loss (for which it is very effective), it is really a program for health. The basic approach of South Beach involves:

Eat good fats — Choose good fats from olive oil, canola oil, peanut oil, flaxseed oil, walnut oil, avocados, nuts, and fish. Omega-3 (fish oil) supplements are also fine.


Eat good carbs — Good carbs include high-fiber, nutrient-dense fruits, vegetables, legumes, and whole grains.

Eat lean protein — Good sources include eggs, low-fat dairy, nuts, seeds, legumes, skinless white-meat poultry, fish, shellfish, lean cuts of meat, and vegetarian options such as tofu.

(From The South Beach Diet, Dr. Arthur Agatston)


There's no doubt that South Beach can yield dramatic weight loss. In my experience, the success in weight loss depends on 1) how unhealthy your diet was in the first place, and 2) how long you can stick to Phase I, the inital phase during which weight loss is most dramatic. Some people have to periodically cycle back to Phase I to break a "plateau" or to lose faster.

But South Beach is also healthy. It has all the ingredients of a healthy eating program: Low saturated and hydrogenated fats, rich in monounsaturated fats, high fiber, low- to moderate- glycemic index, vegetables and fruits, lean proteins.

The Atkins' diet, in contrast, while very effective for weiglht loss, is an unhealthy process. I've seen lots of bladder infections, constipation, skin rashes, and kidney stones. That's just in the short term. If you stick to the "induction phase" (the no carbohydrate, low fiber, indiscriminate fat initial phase) for an extended period, I suspect that other adverse internal phenemena also develop that might not show for years, like cancer. But--it does work for weight loss!

South Beach's Phase I is also carbohydrate restricted, but steers you towards healthier foods, such as healthy oils from olive and canola, raw or dry roasted nuts, and lean proteins and vegetables.

What really makes South Beach special, however, are its clever recipes. Dr. Arthur Agatston (the author) involved chefs from the restaurants in the South Beach area of Miami to help create healthy yet delicious recipes. We've tried many of them and, while they are different from traditional fare, are delicious and satisfying for the most part.

Criticisms? None, really. But, when my patients choose South Beach (which I often encourage), I often have to impress on them that the Track Your Plaque program is not about weight loss. It is about seizing control of a potentially life-threatening disease. It is a far more important goal with greater implications. Weight loss is just one aspect of a coronary plaque control effort. For this reason, we sometimes have to make changes in the South Beach program to allow for correction of specific lipoprotein patterns.

The most common modification is in people with small LDL particles. This pattern often does indeed respond to weight loss and/or niacin. However, it occasionally persists despite these efforts. We then will ask the patient to continue to restrict the re-introduction of wheat products, though it is allowed after Phase I in South Beach. In other words, for this specific and sometimes difficult to control lipoprotein pattern, a spedific modification of the off-the-shelf South Beach program is sometimes necessary. Of course, the diet is created to suit everybody. Lipoprotein analysis permits detailed insight into your patterns and it's only to be expected that specific modifications might be needed.

But, as written, you can do quite well in your plaque control program by sticking to South Beach.
