Don't be satisfied with "deceleration"

In the Track Your Plaque program, we aim to stop or reduce your heart scan score.

Recall that, without any preventive efforts, heart scan scores can be expected to increase at the average rate of 30% per year (faster at lower scores, slower at higher scores by a quirk of arithmetic).

I am continually surprised at how often people--that is, people not in the Track Your Plaque program--are often content with what I term "deceleration," or the slowing of plaque growth. In truth, most people are content with deceleration of plaque growth because they simply don't know that plaque continues to grow.

For instance, the BELLES Trial (Beyond Endorsed Lipid Lowering with EBT Scanning (BELLES)), reported in 2005 showed that 650 women participants continued to increase heart scan scores 15% whether they took "high-intensity" statin therapy in the form of Lipitor 80 mg or "low-intensity" statin therapy as pravastatin 40 mg, even though the group taking Lipitor experienced twice the amount of LDL reduction. In other words, heart scan scores continued to increase at the same rate of 15% per year regardless of the intensity of LDL lowering by statin drug.

Another study reported in 2006, Effect of intensive versus standard lipid-lowering treatment with atorvastatin on the progression of calcified coronary atherosclerosis over 12 months: a multicenter, randomized, double-blind trial reported similar results. Of the 471 participants, those taking Lipitor 80 mg per day experienced 27% per year plaque growth (LDL cholesterol 87 mg/dl); those taking 10 mg Lipitor experienced 25% plaque growth (LDL 107 mg/dl). The intensity of statin therapy made no difference on the rate of plaque growth.

In other words, if we are content to sit back and take Lipitor or other statin drug, follow the conventional American Heart Association low-fat, low-cholesterol diet, we will experience somewhere between 15 to 27% annual plaque growth--year after year.

No wonder that conventional advice offered by your friendly neighborhood doctor will avoid (postpone?) only one heart attack in four.

Such is the nature of coronary plaque deceleration: growth is modestly slowed, but is not stopped. Nor is it reversed.

In the Track Your Plaque program, we grade deceleration of plaque growth into three distinct stages out of a total of five. (See Winning Your Personal War with Heart Disease: The Track Your Plaque 5 Stages of Success.)

Why be satisfied with deceleration? Why not aim for a total stop to plaque growth? Why not aim for stage 5 of Track Your Plaque success: reversal?

Whole grains and half truths

(For followers of the Heart Scan Blog, below is a re-posting of a recent post. I've moved it up to make it accessible to a number of patients that I asked to look at this post for some conversation about the concept of wheat-free diets.)


TV ads, media conversations, magazine articles, even advice from the American Heart Association and USDA (a la Food Pyramid) all agree: eat more whole grains, get more fiber.

What happens when you follow this advice to add more and more whole grains to your diet? Look around you: People gain weight, they become pre-diabetic and diabetic. Lipids and lipoprotein patterns emerge: increased triglycerides and VLDL, reduced HDL, small LDL. Blood sugar goes up, inflammatory responses are ignited. You feel crumby, cancer risk is increased.

"Official" agencies have urged us to eat more grains, get more fiber and most Americans have complied. We now have a nationwide health disaster that will eventually lead to more people with coronary plaque, more heart disease, more heart attack, more heart procedures.

This is why I've been urging patients to go wheat-free. It has proven an extraordinarily and surprisingly effective strategy for:

1) rapid and profound weight loss
2) raising HDL and reducing triglycerides, VLDL, and small LDL
3) reducing blood sugars, pre-diabetes and diabetes

So here I (re-) post just a sampling of the comments sent by readers of the Heart Scan Blog who have given this idea a try.

It's true! We've done it. My husband and I stopped eating all grains and sugar in February. At this point, we really don't miss them any more. It was a huge change, but it's worth the effort. I've lost over 20 pounds (10 to go)and my husband has lost 45 pounds (20 to go). On top of it, our body shapes have changed drastically. It is really amazing. I've got my waist back (and a whole wardrobe of clothes) - I'm thrilled.

I'm also very happy to be eating foods that I always loved like eggs, avocados, and meats - without feeling guilty that they're not good for me.

With the extremely hot weather this week in our area, we thought we'd "treat" ourselves to small ice cream cones. To our surprise, it wasn't that much of a treat. Didn't even taste as good as we'd anticipated. I know I would have been much more satisfied with a snack of smoked salmon with fresh dill, capers, chopped onion and drizzled with lemon juice.

Aside from weight changes, we both feel so much better in general - feel much more alert and move around with much greater flexibility, sleep well, never have any indigestion. We're really enjoying this. It's like feeling younger.

It's not a diet for us. This will be the way we eat from now on. Actually, we think our food has become more interesting and varied since giving up all the "white stuff". I guess we felt compelled to get a little more creative.

Eating out (or at other peoples' places) has probably been the hardest part of this adjustment. But now we're getting pretty comfortable saying what we won't eat. I'm starting to enjoy the reactions it produces.



Weight loss, increased energy, less abdominal bloating, better sleep--I've seen it many times, as well.

I was a victim of the '80s lowfat diet craze - doc told me I was obese, gave me the Standard American Diet and said to watch my fat (I'm not a big meat eater, didn't like mayo ... couldn't figure out where my fat was coming from! maybe the fries - I will admit I liked fries). I looked to the USDA food pyramid and to increase my fiber for the constipation I was experiencing. Bread with 3 grams of fiber wasn't good enough; I turned to Kashi cereals for 11 years. My constipation turned to steattorrhea and a celiac disease diagnosis! *No gut pains!* My PCP sent me to the gastroenterologist for a colonscopy because my ferritin was a 5 (20 is low range). Good thing I googled around and asked him to do an endoscopy or I'd be a zombie by now.

My symptoms were depression & anxiety, eczema, GERD, hypothyroidism, mild dizziness, tripping, Alzheimer's-like memory problems, insomnia, heart palpitations, fibromyalgia, worsening eyesight, mild cardiomyopathy, to name a few.

After six months gluten-free, I asked my gastroenterologist about feeling full early ... he said he didn't know what I was talking about! *shrug*

But *I* knew -- it was the gluten/starches! My satiety level has totally changed, and for the first time in my life I feel NORMAL!


Feeling satisfied with less is a prominent effect in my experience, too. You need to eat less, you're driven to snack less, less likely to give in to those evil little bedtime or middle-of-the-night impulses that make you feel ashamed and guilty.



An anonymous (female) commenter said:

My life changed when I cut not only all wheat, but all grains from my diet.

For the first time in my life, I was no longer hungry -no hunger pangs between meals; no overwhelming desire to snack. Now I eat at mealtimes without even thinking about food in between.

I've dropped 70 pounds, effortlessly, come off high blood pressure meds and control my blood sugar without medication.

I don't know whether it was just the elimination of grain, especially wheat, or whether it was a combination of grain elimnation along with a number of other changes, but I do know that mere reduction of grain consumption still left me hungry. It wasn't until I elimnated it that the overwhelming redution in appetite kicked in.

As a former wheat-addicted vegetarian, who thought she was eating healthily according to all the expert advice out there at the time, I can only shake my head at how mistaken I was.


That may be a record for me: 70 lbs!!


Stan said:

It's worth it and you won't look back!

Many things will improve, not just weight reduction: you will think clearer, your reflexes will improve, your breathing rate will go down, your blood pressure will normalize. You will never or rarely have a fever or viral infections like cold or flu. You will become more resistant to cold temperature and you will rarely feel tired, ever!



Ortcloud said:

Whenever I go out to breakfast I look around and I am in shock at what people eat for breakfast. Big stack of pancakes, fruit, fruit juice syrup, just like you said. This is not breakfast, this is dessert ! It has the same sugar and nutrition as a birthday cake, would anyone think cake is ok for breakfast ? No, but that is exactly the equivalent of what they are eating. Somehow we have been duped to think this is ok. For me, I typically eat an omelette when I go out, low carb and no sugar. I dont eat wheat but invariably it comes with the meal and I try to tell the waitress no thanks, they are stunned. They try to push some other type of wheat or sugar product on me instead, finally I have to tell them I dont eat wheat and they are doubly stunned. They cant comprehend it. We have a long way to go in terms of re-education.

Yes. Don't be surprised at the incomprehension, the rolled eyes, even the anger that can sometimes result. Imagine that told you that the food you've come to rely on and love is killing you!


Anne said:

I was overweight by only about 15lbs and I was having pitting edema in my legs and shortness of breath. My cardiologist and I were discussing the possible need of an angiogram. I was three years out from heart bypass surgery.

Before we could schedule the procedure, I tested positive for gluten sensitivity through www.enterolab.com. I eliminated not only wheat but also barley and rye and oats(very contaminated with wheat) from my diet. Within a few weeks my edema was gone, my energy was up and I was no longer short of breath. I lost about 10 lbs. The main reason I gave up gluten was to see if I could stop the progression of my peripheral neuropathy. Getting off wheat and other gluten grains has given me back my life. I have been gluten free for 4 years and feel younger than I have in many years.

There are many gluten free processed foods, but I have found I feel my best when I stick with whole foods.



Ann has a different reason (gluten enteropathy, or celiac disease) for wanting to be wheat-free. But I've seen similar improvements that go beyond just relief of the symptoms attributable to the inflammatory intestinal effects of gluten elimination.

I have relatively successfully cut carbs and grains from my diet thus far.

Because I've got some weight to lose, I have tried to keep the carb count low and I've lost 15 pounds since then.

I have also been very surprised at the significant reduction in my appetite. I've read about the experience of others with regard to appetite reduction and couldn't really imagine that it could happen for me too. But it has.

A few weeks ago, I attended a party catered by one of my favorite italian restaurants and got myself offtrack for two days. Then it took me a couple of days to get back on track because my appetite returned.

Check out Jimmy Moore's website for lots of ideas about variations of foods to try. The latest thing I picked up from Jimmy is the good old-fashioned hard boiled egg. Two or three eggs with some spicy hot sauce for breakfast and a handful of almonds mid-morning plus a couple glasses of water and I'm good for the morning no problem.

I find myself thinking about lunch not because I'm really hungry but out of habit.

The cool thing too now is that the more I do this, the more I'm just not tempted much to do anything but this diet.



Going wheat-free, along with a reduction in processed sugary foods like Hawaiian Punch, sodas, and candy, is the straightest, most direct path I know of to lose weight, obtain all the health benefits listed by our commenters, as well as achieve the lipoprotein corrections we seek, like reduction of small LDL particles and rise in HDL, in the Track Your Plaque program.

Fasting and heart disease

Followers of the Track Your Plaque program know that we advocate periodic fasts to reduce heart disease risk.

I came across an interesting report form an abstract presented at last week's American Heart Association meetings in Orlando:

(Read the report at HeartWire. You will need to register or sign-in.)

In this study, the investigators tried to determine why members of the Church of Jesus Christ of Latter-Day Saints (LDS) tended to have reduced risk of heart disease compared to others in the area but not in the LDS faith. While the reduced risk of heart disease in LDS members had been traditionally attributed to the no smoking policy advocated by the Mormon church, the investigators suspected that there was more to the reduced risk.

Of 515 people interviewed, periodic fasting, whether for religious or other reasons, was found to distinguish people who were less likely to have coronary disease by conventional catheterization (59% vs. 67%). (Since the study was published in only abstract form, it's not clear why all these people underwent heart catheterization in the first place.)

Nonetheless, it's an interesting observation and one consistent with the benefits we see when someone fasts: reduced blood pressure, reduced inflammatory responses, improved lipids and lipoproteins, weight loss.

Fasting can be an especially effective method to gain control over heart disease and coronary plaque if rapid control is desired. In fact, I wonder if the normally year-long process of plaque control that I advocate can be much abbreviated. Fasting, I believe, is a crucial component of rapid control, what I've talked about in Instant Heart Disease Reversal

There's also additional thoughts on fasting in my Heart Scan Blog post, For rapid success, try the "fast" track.

Fasting is not something to fear. It can be an enlightening process that can serve to abruptly sever bad habits, perhaps even turn the clock back on prior dietary and lifestyle excesses. My favorite variation on fasting is to use soy milk (yes, yes, I know! I can already hear the the soy bashers screaming!) as a meal substitute. It is an easy, less dramatic way that still maintains most of the benefit of a full, water-only fast.

Coronary arteries aren't what they seem

Why do stress tests so often fail to detect coronary atherosclerotic plaque? Why do even heart catheterizations--the "gold standard"--fail to disclose the full extent of plaque within the walls of coronary arteries?

We owe much of the explanation of these phenomena to Dr. Seymour Glagov, retired professor of pathology at the University of Chicago.



When studying the coronary arteries of people who died, he observed that people commonly had plenty of atherosclerotic plaque lining the artery wall, yet it did not necessarily impinge on the artery "lumen," or the internal path for blood to flow.

The only time the lumen became obstructed by plaque was when either 1) plaque grew to overwhelming levels and was severe and extensive, or 2) when a plaque had "ruptured," meaning its thin covering had been penetrated and eroded by the underlying plaque tissue like a volcano emerging from the surface and erupting.

This groundbreaking observation, now dubbed "the Glagov phenomenon," explains why someone can have a normal stress test on Tuesday but erupt a plaque on Wednesday.

The Glagov phenomenon also explains why heart scans can detect plaque when both stress tests and heart catheterizations fail to do so. Many physicians will then interpret this to mean that the heart scan was wrong. With the Glagov phenomenon in mind, you can see that the heart scan is not wrong, it is simply detecting coronary atherosclerotic plaque at a stage that is not yet detectable by the other methods.

In the illustration, you can see that the lumen of the vessel is maintained--despite the artery on the left having minimal plaque, the artery on the right containing moderate plaque. If either artery were examined by a test that relies on blood flow--stress test or heart catheterization--both would appear normal. But a test that examines the artery wall, such as a heart scan, would readily detect the artery on the right and probably even the artery on the left.




I am very grateful to Dr. Glagov and his insight into this important process. Otherwise, we might still be floundering around trying to understand the apparent discrepances between these tests that simply provide different perspectives on the same problem.

Heart disease reversal a big "No No"

I dare you: Ask your doctor whether coronary heart disease can be reversed.

My prediction is that the answer will be a flat "NO." Or, something like "rarely, in extraordinary cases," kind of like spontaneous cure of cancer.

There are indeed discussions that have developed over the years in the conventional scientific and medical literature about reversal of heart disease, like Dean Ornish's Lifestyle Heart Trial, the REVERSAL Trial of atorvastatin (Lipitor) and the ASTEROID Trial of rosuvastatin (Crestor). Reversal of atherosclerotic plaque in these trials tends to be small in scale and sporadic.

Of course, the medical literature is swamped with studies that have nothing to do with reversal, like what stent is best, what platelet-inhibiting intravenous drug is best, when should angioplasty or stents be used and when, do implantable defibrillators save lives, improvements in coronary bypass techniques, etc. There are tens of thousands of these studies for every study that focuses on the question of atherosclerotic plaque reversal.

The concept of reversal of heart disease has simply not gained a foothold in the lexicon nor in the thinking of practicing physicians. Heart disease is a relentlessly, unavoidably, and helplessly progressive disease in their way of thinking. Perhaps we can reduce the likelihood of cardiovascular events like heart attack and death with statin drugs and beta blockers. But reverse heart disease ? In your dreams!

We need to change this mentality. Heart disease is a reversible phenomenon. Atherosclerosis in other territories like the carotid arteries is also a reversible pheneomenon. Rather than throwing medicines and (ineffective) diets at you (like the ridiculous American Heart Association program), what if your doctor set out from the start not just to reduce events, but to purposefully reduce your heart's plaque? While it might not succeed in everyone, it would certainly change the focus dramatically.

After all, isn't this the theme followed in cancer treatment? If you had a tumor, isn't cure the goal? Would we accept an oncologist's advice to simply reduce the likelihood of death from cancer but ignore the idea of ridding yourself completely of the disease? I don't think so.

Then why accept "event reduction" as a goal in heart disease? We shouldn't have to. Heart disease reversal--elimination--should be the goal.

Demystification

Once upon a time, remember how medical information was mysterious, hospitals were places where frightening, inscrutable things happened, diseases were strange maladies that struck without reason, and obtaining information about health was like hunting for buried treasure? The full extent of many peoples' understanding of health came through relatively anemic sources like Readers' Digest. (Remember "I am Joe's Colon"?)

Compare this to what we have now. If I wanted to obtain information about ankylosing spondylitis (a rare genetic disease of the spine), a Google search yields 1.46 million citations. Not all the information, of course, is helpful or relevant, but there's certain to be a bounty of information that far exceeds what you could have uncovered 40 years ago.




Suppose you enter the search phrase "antithrombin III" into your Google search. Citations: over 900,000. (The number of search citations, in fact, exceeds the number of Americans with a deficiency of this blood clotting protein!)

The same is true with heart disease. There was a time, not more than 30-40 years ago, when information about the heart and heart disease was hard to come by. The most you would find were superficial discussions about heart attacks, what chest pain means, descriptions of bypass surgery. Ask your doctor, you'd likely receive a brief, cursory response about how you probably shouldn't worry it.

Even during medical school in the 1980s, I remember struggling to get answers to my questions from faculty during medical school and medical training. It was as if providing too much information would eliminate the advantage superiors wielded over trainees.

The same selfish sentiment, the "I know something you don't know" mentality reminiscent of a schoolboy's "naa na na naa naa!" unfortunately persists. But it is rapidly disintegrating. Soon it will join the junk heap of medical mis-information accumulated over the years (a big pile, to be sure). The internet and, I'll admit (grudgingly), the media, have been responsible for demystifying the formerly mysterious and indecipherable world of health.

You now have, at a moment's disposal, access to an extraordinary array and breadth of health information that was inconceivable just a few years ago.

Times are changing. Doctors no longer hold the monopoly over health information. The public--YOU--are rapidly becoming the arbiters of health, the informed consumers of a soon-to-be retail product called health care, and the increasingly savvy judges of what should join the mainstream path of health. It is all part of this wave of change that I've been advocating: the emerging concept of self-empowerment in healthcare.

Added to the junk heap of health-mistakes-of-years-past will be medical protectionism over health information, heart procedures, drug industry excesses, nutritional mis-information, among others. The demystification of health information will open the floodgates of individual insight into health. It delivers control over your own health destiny straight into your own lap.

Everything has omega-3

Walking the supermarket aisles, you may have lately noticed that numerous new products are appearing sporting "omega-3s" on the label.

Some products simply contain alpha-linolenic acid, a tiny amount of which is converted to the biologically active omega-3s, EPA and DHA. Natural Ovens' Brainy Bagel, for instance, carries a claim of "620 omega-3."



I find this confusing and misleading, since people will often interpret such a claim to mean that it contains 620 of EPA and DHA, similar to two capsules of standard fish oil (1000 mg capsules). Of course, it does NOT. I find this especially troublesome when people will actually stop or reduce their fish oil, since they've been misled into thinking that products like this bread contain active omega-3 fatty acids that yield all the benefits of the "real stuff."


Other products actually contain the omega-3, DHA, though usually in small quantities. Breyer's Smart with DHA is an example, with 32 mg DHA per container.


I find products with actual DHA (from algae) a more credible claim. However, the Center for Science in the Public Interest (CSPI) has looked at the actual contents of DHA in some of these products and found some discrepancies, including amounts of DHA less than the labeled amount and claims of omega-3 wihtout specifying DHA vs. linolenic acid. (It's probably linolenic acid, if it's not specified.)

All in all, the addition of DHA to food products is a nice way to boost your intake of this healthy omega-3. However, keep in mind that these are processed, often highly processed, foods and you will likely pay a premium for the little boost. For now, stick to fish oil, the real thing.

For a brief summary of the CSPI report and a link to the Nutrition Action Newsletter, see Omega-3 Madness: Fish Oil or Snake Oil.

Are cardiologists the enemy?

I'm sitting at dinner with two colleagues. One is a cardiology colleague, another an internist who, in addition to practicing general internal medicine, also takes heart disease prevention very seriously. He has, in fact, participated in the Track Your Plaque program and dropped his heart scan score substantially.

"Why don't we see you in the cath lab much?" my cardiology colleague asked me. He was puzzled, since he knew my background in cath lab work from years before, spending day and night doing procedure after procedure. He spends virtually all his days there.

"Well, my patients simply don't have events any more. Heart attacks and angina among people in my program are just about non-existent. They don't have symptoms and they don't have to go to the hospital. I can't remember the last time that I was woken up in the middle of the night for an urgent procedure for one of my patients."

The internist across the table smiled and expressed his agreement. "That's the same thing I'm seeing: No heart attacks, very few if any referrals to cardiologists for procedures. I remember when it was a several times a week thing. Now, almost never. "

Looking at my cardiology colleague, I saw the usual cardiologist reaction: Eyes searching left and right and behind us for something more interesting. Certainly, talking about a virtual cure for coronary heart disease was just too damn dull.

Such is the attitude of 98% of my colleagues: If it doesn't generate a revenue-producing procedure, why bother? Prevention is for general practitioners, the line of thinking goes. "And anyway, I'm too busy doing procedures! I don't ahve time to talk about prevention and health!" Of course, the poor general practitioner is already overloaded with caring for arthritis, flu, diabetes and all the new drugs for diabetes, headaches, vaccinations, diarrhea, and . . .oh, yes, heart disease prevention.

Are cardiologists the enemy? No, of course they are are not. But they often act like they are. Talking to cardiologists is like going to the car dealer with your checkbook out, pen in hand. The salesman gets to write the check himself and you just sign it. Talk to a cardiologist and more often than not you will end up with a heart procedure--whether or not you need it.

Unfortunately--tragically--they often forget what they are supposed to be doing: Taking care of a disease by preventing it. Putting in a defibrillator is not preventing a disease. Putting in three stents, laser angioplasty, and thrombectomy are not ways of preventing a disease.

I'm thankful for my internist friend who sees the light. Coronary heart disease is a an easily measurable, quantifiable, preventable, and REVERSIBLE process for many, if not most, people when provided the right tools. But don't ask your neighborhood cardiologists to give you those tools.

Are CETP inhibitors kaput?

Was torcetrapib’s crash and burn fatal for this class of drug?

At the 2007 American Heart Association meetings in Orlando, Florida, Dr. Philip Barter of Sydney, Australia, presented an update of the ILLUMINATE drug trial for the once-promising drug, torcetrapib, the billion-dollar bet that Pfizer made on its first entry into the new drug class.

You may recall that the crash and burn of Pfizer’s torcetrapib in December 2006 made headlines and prompted enormous disappointment for many patients and doctors who had hoped for a new drug choice to raise HDL cholesterol. Pfizer executives (heads flew!) and investors were also disappointed, anticipating release of a drug that might have become the number one biggest selling drug in the world—ever, surpassing even Lipitor's® $13 billion annual sales.

Torcetrapib is the first among the “cholesteryl-ester transfer protein inhibitors,” or CETP-inhibitors, drugs that block the exchange of cholesterol and triglycerides between HDL and VLDL particles and prevent formation of the unwanted small LDL particles. Preliminary efforts suggested that effects were positively enormous.

However, the 15,000-participant trial was abruptly terminated after 550 days when an excess of deaths were identified among the group taking the experimental drug: 59 deaths in control group; 93 deaths in the torcetrapib group.

In addition, cardiovascular events were 24% greater in the torcetrapib group, numbering 373 compared to 464 in the no-torcetrapib group, including a substantially greater number of heart attacks and hospitalizations. Another surprise came in the way of cause of death among some of the torcetrapib patients, with an excess of deaths due to cancers (twice as many in the torcetrapib group), strokes, and infections.

Why the divergence: enormous improvements in cholesterol values, yet increase in adverse effects including more heart attack? Deeper digging by the principal investigators uncovered unexpected distortions of electrolytes like sodium and potassium. They then re-analyzed blood samples from participants on both sides of the trial and discovered that participants taking torcetrapib experienced significant rise in the blood pressure hormone, aldosterone. This, they surmised, also likely accounted for the 4 mmHg average rise in blood pressure among those taking the experimental drug. (This is the same pathway blocked by blood pressure drugs like ACE inhibitors lisinopril and enalapril, ARBs like losartan.)

Simultaneously (what a coincidence!) with the torcetrapib data, investigators at competing drug manufacturer, Merck, reported encouraging data with their version of CETP inhibitor, anacetrapib. In a phase II FDA trial of 589 patients, anacetrapib reduced LDL-C levels by up to 40% and increased HDL-C up to 139%.


Spokesman Daniel Bloomfield, M.D., of Merck Research Laboratories reported that "The favorable lipid effects seen in this study with multiple doses of anacetrapib were significant, and confirm the continued evaluation of the clinical benefits of CETP inhibitors in the treatment of dyslipidemia." Quick to distinguish this drug from torcetrapib’s track record of dangerous effects on blood pressure, he added that "the decreased LDL-C concentrations, increased HDL-C concentrations and no demonstrable increase in blood pressure seen with anacetrapib are particularly encouraging results of this study."

However, the data reported only an 8 week expereince. Given the experience with torcetrapib, longer term data will obviously be required to assess safety. After Pfizer spent over $1 billion and sacrificed lives to obtain this experience, Merck will need to tread carefully.

It will clearly be many years before we have a confident answer on whether the CETP-inhibitor class of drugs will be a safe choice for correction of cholesterol abnormalities, especially low HDL. Are we helpless until then?

Though CETP inhibitors offer the potential for a one-stop opportunity to raise HDL substantially, there are still many strategies available to raise HDL.

Strategies that raise HDL and are available today include:
• Weight loss—to your ideal weight. A very effective strategy.
• Reduction in processed carbohydrates—like breads, pasta, cookies, pretzels, etc. Note that very low-fat diets reduce HDL. Often a huge effect.
• Fish oil—A small effect, more dramatic when triglycerides are high.
• Niacin—Vitamin B3, the best we have at present. Doses of 500-1500 mg per day raise HDL 20–50%; work with your doctor if you are contemplating niacin. We use this agent everyday and have had great success; good hydration is key to minimize the annoying “hot-flush” effect.
• Dark chocolate—40 grams, or about 2 inches square, a delicious way to squeeze out a little rise in HDL.
• Alcoholic beverages—Red wines are almost certainly the preferred route, rich in flavonoids.
• Exercise—HDL-raising effects vary, but can sometimes be as much as 10–20 mg.
• Other drugs—Though not commonly used for this effect, drugs like pioglitazone (for diabetes and pre-diabetes); fibrates (Tricor® or fenofibrate; Lopid® or gemfibrozil); and Pletal® or cilostazol are occasionally prescribed.
• Vitamin D—You won’t find validation of this effect in any scientific study, but our emerging experience in our heart disease reversal program is suggesting that this neglected nutrient can exert powerful HDL-raising effects. In fact, supplementing vitamin D has made my life much easier.


And, last I checked, none of these HDL-raising strategies are ever fatal.

Roto Rooter for plaque




Joe, a machinist, was frightened and frustrated.

With a heart scan score of 1644 at age 61, his eyes bulged when I advised him that, if preventive efforts weren't instituted right away, his risk for heart attack was a high as 25% per year. Joe had "passed" a stress test, thus suggesting that, while coronary plaque was present--oodles of it, in fact--coronary blood flow was normal. Thus, there would be no benefit to inserting three stents, say, or a bypass operation.


(Illustration courtesy Wikipedia)

"I don't get it, doc. Why can't you just take it out? You know, like Roto-Rooter it out? Or give me something to dissolve it!"

Of course, if there were such a thing, I'd give it to him. But, of course, there is not. It doesn't mean that there haven't been efforts in this direction over the years. Among the various attempts made to "Roto-Rooter" atherosclerotic plaque have included:

Coronary endarterectomy
This is a drastic procedure rarely performed anymore but enjoyed some popularity in the 1980s and 1990s. Coronary endarterectomy was performed during coronary bypass surgery, but few thoracic surgeons performed it. Milwaukee's Dr. Dudley Johnson was the foremost practitioner of this procedure (retired a few years ago after his own bypass operation) with a mortality in excess of 25%. A very dangerous procedure, indeed. The technical hurdle, beyond the tedium and length of time required to remove plaque that had a tendency to fragment, was blood clot formation after tissue was exposed upon plaque removal. I saw many lengthy hospital stays and deaths following this procedure.

Coronary atherectomy
This is an angioplasty-type procedure that has gone through several variations over the years.

In the early 1990s, transluminal extraction atherectomy (TEC) was a technique involving low-rpm drill bits with a suction apparatus that was used to clear soft debris, usually from large coronary arteries or, more commonly, bypass grafts. Then came direction atherectomy, in which a steel housing contained a sharp drill bit that captured atherosclerotic plaque in an aperture along the housing length and stuffed it into a nosecone, retrieved once the device was removed.

Then came high-speed rotational atherectomy in which a diamond-tipped drill bit rotated up to 200,000 rpm and essentially pulverized plaque to flow downstream and, presumably, eventually captured by the liver for disposal. Rotational atherectomy is still in use on occasion. Laser angioplasty, usually using the excimer wavelength, vaporizes plaque. I did plenty of all of these back in the early and mid-1990s.

While all atherectomy procedures sound clever, they are all plagued by the same problem: vigorous return of plaque. Remove plaque, it grows back. There are few instances today in which atherectomy is still performed.

Chelation
This involves a metal-binding, or "chelating," agent like EDTA normally used in conventional practice for lead poisoning. Usually administered IV, some have also advocated oral use. People who use chelation also tend to believe in faith healing and other practices based on faith, not science. There is an international trial that is nearing completion that should provide the final word on whether there is any role to intravenous chelation.

There are numerous other oral treatments that claim a Roto-Rooter-like effect. Nattokinase, for example--an outright, unadulterated, and unqualified scam.

Unfortunately, the helpless, ignorant, and gullible are many. When frightened by the specter of heart disease, there are plenty of people who will willingly pay for the hope provided by clever ads, fast-talking salespeople, and unscrupulous practitioners.

So, Joe, there is no Roto-Rooter for coronary atherosclerotic plaque, at least one that is safe, doesn't involve a life-threatening effort, provides results that endure beyond a few months, and truly works.

The Track Your Plaque program may not be easy. There are obvious common hurdles to adhering to these concepts: obtaining lipoprotein testing, getting intelligent interepretation of the results, persuading your doctor to measure vitamin D blood levels, battling the onslaught of prevailing food propaganda that confuses and misleads. The Track Your Plaque program also requires time, at least a year.

But it's the best program there is. Do you know of anything better?

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.

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.
