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?

Firefighters Face Added Risk of Fatal Heart Attack

Firefighters are twice as likely to die from a heart attack in the line of duty than are policemen, and three times more likely than EMTs.

That's among the headlines run today because of a report in the New England Journal of Medicine documenting a dramatically higher risk for heart attack for fire fighters putting out fires. The above headline is from an excellent report run on NPR radio. You can listen to the webcast at http://www.npr.org/templates/story/story.php?storyId=9047656.

The story sparked comments from experts insisting that all fire fighters should have physicals, should be in better physical condition, should be covered by health insurance (the NPR report said that 1 out of 4 fire fighters lack health insurance). Judging from the indisputable risk firefighters encounter, these are all good ideas.

But if you've been following my blog or the Track Your Plaque program, you know that physicals alone are hopeless exercises for identifying hidden heart disease. Among the solutions: identify whether or not heart disease is present in the first place--do a CT heart scan.

In fact, several local fire companies in my area have done just that: insisting that all firefighters undergo a heart scan. When groups of people like firefighters arrange for heart scans, they gain the advantage of doing so en masse, thereby allowing many scan centers to offer a dramatically reduced price to the city, town, or village that is paying for them. I've even seen many firefighters scanned at no cost.

It would also help to have health insurance, be physically fit, and have a stress test (an exception to my view that stress tests are also useless to screen asymptomatic people for heart disease). But a CT heart scan would settle the question quickly, easily, undeniably, and inexpensively.

Prophylactic bypass surgery?

This question comes up around once a week:

My CT heart scan score is ____. Wouldn't I be better off just getting a bypass (or stent, etc.) and getting it over with? If I know that heart attack is in my future, why not just get it over with?

The most recent source of this question was the wife of a patient. Jack had a heart scan score of 92 in 2005. He made very little effort to correct his causes, permitting pre-diabetic patterns to persist, failed to correct vitamin D, etc. and a repeat heart scan score showed a dramatic rise to 264.

Jack's wife asked whether he should just have a bypass.

There are several problems with this line of reasoning:

1) Bypass surgery does not reduce the long term risk for heart attack.

2) The risk of bypass surgery often outweighs the risk of an asymptomatic heart scan score.

3) Bypass surgery is a temporary "fix," a fancy Band Aid for a disease that progresses after the procedure. One bypass typically prompts another, and another...

4) Bypassing arteries that have vigorous blood flow often causes the bypass graft to not "take" and close within the first few days.


Thankfully, nobody in his right mind has proposed that we perform prophylactic bypass operations.

Of course, hospitals and surgeons would jump at the chance to perform procedures in anybody with some threshhold heart scan score. It would double or triple their business overnight. At $70,000 or more per procedure, they would dance in glee. Of course, you and I would pay for their new burst of wealth by a sharp increase in our health insurance premiums. Not only that, the people who underwent the procedure would not benefit.

Lipitor 80 mg

I'm seeing more and more people taking 80 mg of Lipitor per day. For the most part, these are people who come in for another opinion after a stent or heart attack and are prescribed the drug during their hospitalization.

This practice is based on the results of the PROVE IT-TIMI 22 (PRavastatin Or atorVastatin Evaluation and Infection Therapy-Thrombolysis In Myocardial Infarction) trial, and the Reversal of Atherosclerosis with Aggressive Lipid Lowering (REVERSAL) trial, both reported in 2005. In the PROVE IT Trial, 4,000 people experiencing heart attacks were treated with Lipitor (atorvastatin), 80 mg, or Pravachol (pravastatin), 40 mg. There was a reduction in events like recurrent heart attack from 13.1% in the Pravachol group to 9.6% in the Lipitor group. In the REVERSAL Trial, the Lipitor group also showed no plaque growth compared to the Pravachol group, which did progress, with disease tracked by intracoronary ultrasound.

I believe that many of my colleagues took the bait. In a half-hearted effort to reduce events and trend towards better coronary plaque control, writing a prescription for 80 mg rather than a lower dose has become increasingly popular.

Some problems: Despite the favorable tolerance to high dose Lipitor in these trials, I don't know anybody who can tolerate 80 mg per day for more than a few months in real life. In my experience, people inevitably end up with intolerable muscle aches.

Also, I believe it is folly to believe that we can regress coronary plaque on a broad scale by just using one drug that addresses only a single cause (i.e., LDL cholesterol). Yes, drug companies would argue that the statin drugs are so wonderful because of their so-called "pleiotropic", or non-lipid, effects like reducing inflammation. I have seen regression of plaque once using Lipitor alone. We struggle to reduce coronary plaque using a multi-faceted approach. It is highly unlikely that Lipitor alone at a 80 mg dose will be sufficient in most people to regress plaque. How about lipoprotein(a)? Or vitamin D deficiency? Lipitor has no effect on these patterns and people do not regress just by taking statin agents.

Orlistat for weight loss

In early February, the FDA approved orlistat, formerly known as prescription Xenical, for over-the-counter sale. Orlistat is a blocker of fat absorption.

The new OTC version will be called "Alli" (pronounced like "ally") and will come at a dose of 60 mg to be taken three times a day with meals. Prescription Xenical came as a 120 mg tablet. However, the company claims that the reduced dose sacrifices only 5% in reduced fat absorption, dropping from 30% with Xenical to 25% with Alli. It will cost in the neighborhood of $1 to $2 per day, or $30-60 per month, far less expensive than the $110-150 for the prescription form.

Does it work? Is it worth the money? Clinical trials document around 5-10 lbs lost over a 3 to 6 month period, 50% greater than using diet and exercise alone.

Our experience is that it works, though inconsistently. Results depend heavily on how reliant you are on fat calories. If you were to follow a low-fat diet while on the drug, you likely will lose little or no weight, since there's little fat absorption to block. However, I have witnessed more substantial weight loss of 10-20 lbs. in people who follow a higher fat intake in their diet, e.g., a traditional American diet. However, these people gain the weight back immediately because they've made no effort to modify food choices.

It is messy. Even though the clinical trials claims modest inconvenient effects like gas and greasy stools, I have found that it is, without fail, a very annoying product that results in crampiness and frequent messy stools in nearly everybody.

The company has created a glitzy website that you can view at www.myalli.com and promises to provide a personalized program and support for registrants when it is up and running by summer 2007.
I think that's a good idea, since the drug itself is no more than a temporary fix unless it's combined with long-term diet changes. However, the website, I believe, oversells the value of the drug with a drug company's usual over-the-top hints and innuendoes without actually coming out with straight pitches of the truth.

Beware of the vitamin D-blocking effect of Orlistat. The period of time you take it may be a time to resort to some modest sun exposure (10-15 minutes; be careful not to burn), rather than than oil-based vitamin D capsules, in order to avoid the inevitable vitamin D plunge in blood level.

I am not a fan of orlistat, having seen it tried many times with minimal success. However, it is another option for those who are really struggling. Personally, I would try fasting or some of the other strategies we've detailed on the www.cureality.com website before I resorted to orlistat.

Low HDL makes Dr. Friedewald a liar

There's a $22 billion industry based on treating LDL cholesterol, a fictitious number.

LDL cholesterol is calculated from the following equation:

LDL cholesterol = Total cholesterol - HDL cholesterol - triglycerides/5

So when your doctor tells you that your LDL cholesterol is X, 99% of the time it has been calculated. This is based on the empiric calculation developed by Dr. Friedwald in the 1960s. Back then, it was a reasonable solution, just like bacon and eggs was a reasonable breakfast and a '62 Rambler was a reasonable automobile.

One of the problems with Dr. Friedewald's calculation is that the lower HDL cholesterol, the less accurate LDL cholesterol becomes. If it were just a few points, so what? But what if it were commonly 50 to 100 mg/dl inaccurate? In other words, your doctor tells you that your LDL is 120 mg/dl, but the real number is somewhere between 170 and 220 mg/dl. Does this happen?

You bet it does. In my experience, it is an everyday event. In fact, I'm actually surprised when the Friedewald calculated LDL closely approximates true LDL--it's the exception.

Dr. Friedewald would likely have explained that, when applied to a large population of, say, 10,000 people, calculated LDL is a good representation of true LDL. However, just like saying that the average weight for an American woman is 176 lbs (that's true, by the way), does that mean if you weigh 125 lbs that you are "off" by 41 lbs? No, but it shows how you cannot apply the statistical observations made in large populations to a single individual.

The lower HDL goes, the more inaccurate LDL becomes. This would be acceptable if most HDLs still permitted reasonable estimation of LDL--but it does not. LDL begins to become significantly inaccurate with HDL below 60 mg/dl.

How to get around this antiquated formula? In order of most accurate to least accurate:

--LDL particle number (NMR)--the most accurate by far.

--Apoprotein B--available in most laboratories.

--"Direct" LDL

--Non-HDL--i.e., the calculation of total cholesterol minus HDL. But it's still a calculated with built-in flaws.

--LDL by Friedewald calculation.

My personal view: you need to get an NMR if you want to know what your LDL truly is. A month of Lipitor costs around $80-120. A basic NMR costs less than $90. It's a relative bargain.

Menopause unleashes lipoprotein(a)

Faye was clearly frustrated.

At age 52, she was having chest pains every day. A CT heart scan showed a score of zero. A CT coronary angiogram showed no plaque whatsoever.

"Everything went downhill when my menopause started. I gained weight, I started to have chest pains, my blood pressure went up, my cholesterol shot up."

She saw three physicians, none of whom shed much light on the situation. They ran through the predictable sequence of (horse, not human) estrogens, anti-depressants, suggestions for psychological counseling.

But we checked Faye for lipoprotein(a), which she proved to have at a high level of 182 nmol/l. This explained a lot.

A curious and predictable set of phenomenon occur to females with Lp(a) proceeding through the menopause. As estrogen recedes:

--Lp(a) levels rise dramatically.

--Blood pressure goes up, sometimes creating severe hypertension by mid- to late-50s.

--Chest pain can develop, presumably due to "endothelial dysfunction" or "microvascular angina", both representing abnormal coronary artery constriction facilitated by worsening expression of Lp(a).

All too often, these phenomena get dismissed as simply part of the menopausal package, when they are, in fact, important facets of this very important genetic pattern that confers high risk for heart disease.

If any of this rings familiar for you or a loved one, think Lp(a). Though Faye hadn't yet developed any measurable coronary plaque by her CT heart scan score, it was likely on its way, given the surge in Lp(a) expression as menopause unfolded--unless its recognized and appropriate preventive action taken.

Vitamin D must be oil-based

I've talked about this before, but I need to periodically remind everybody:
Vitamin D must be an oil-based capsule, a gel-cap, not a tablet.

Lisa is one of early success stories: a heart scan score of 447 in her early 40's, modest reduction of CT heart scan score three years ago.

However, Lisa had a difficult time locating oil-based vitamin D. There has, in fact, been a national run on vitamin D and I'm told that even manufacturers are scrambling to keep up with the booming demand. So, she bought tablets instead and was taking 3000 units per day.

She came in for a routine check. Lisa's 25-OH-vitamin D3: 17 ng/ml, signifying severe deficiency, the same as if she were taking nothing at all. (Recall that we aim for 50 ng/ml.)

In other words, vitamin D tablets do not work. It is shameful. I see numerous women taking calcium tablets with D--the vitamin D does not work. I've actually seen blood levels of zero on these preparations.

You may have to look, but if you want to enjoy the extraordinary benefits of vitamin D replacement, it must be an oil-based capsule. Carlson's and Vitamin Shoppe have excellent prepartions. They raise blood levels substantially and consistently, and they're inexpensive. We pay $5.99 for a bottle of 120 capsules.

Vitamin D for $200?

What if vitamin D cost $200 rather than $2?

In other words, what if cholecalciferol, or vitamin D3, was a patent-protectable agent that would sell for an extravagant price, just like a drug?

Vitamin D would be the hot topic. There would be TV ads run during Oprah, slick magazine two-page spreads with experts touting its outsized benefits, insurance companies would battle over how much your copay should be.

The manufacturer would host large fancy symposia to educate physicians on how wonderful vitamin D is for treatment of numerous conditions, complete with dinner, a show, and gifts. They would hire expert speakers to speak, scientists to have articles ghost-written, give out knick knacks with the brand label inscribed--just like Lipitor, Actos, Vytorin, ReoPro, Plavix . . .

After all, what other "drug" substantially increases bone density (up to 20% in adult females), enhances insulin responses 30% (equivalent to the TZD drugs, Actos and Avandia), and slashes colon cancer risk?

But it's not a drug. That is both vitamin D's strength and its weakness. It's a strong point because it's natural, phenomenally helpful across a variety of conditions, and inexpensive. It is also a weakness because, at $2 a month, no one is raking in the $12 billion annually that Pfizer makes for Lipitor that allows it to fund an enormous marketing campaign.

Vitamin D is a "discovery" of huge importance for health, including making reductions of CT heart scan scores far more likely for more people. And it comes without a prescription.

What's up with garlic?


Fanatic Cook has posted an excellent summary on the recent negative attention cast on garlic preparations, at least for LDL cholesterol reduction.

Go to http://fanaticcook.blogspot.com to view.

I think Fanatic Cook is right--despite the lack of LDL reducing effects, it doesn't necessarily mean no benefit whatsoever. Anti-coagulation and anti-inflammatory effects, in particular, are well proven.

I do think, however, that it argues more in favor of sticking to whole cloves, rather than supplements. The benefits are also likely small. I would view garlic as a soft advantage for your plaque control program. You can do fine without it. You might do slightly better with it.

Drop the pretense

Most hospitals maintain the "Saint _____" in their names, despite many having little or nothing to do with the church.

Out of 15 hospitals in my area, 13 are named after saints.

In my view, a more honest name would be something like "ABC Medical Enterprises, Inc." The profit motive, aggressive marketing tactics, and high CEO salaries would make better sense then. The trend to convert practicing physicians from professionals acting on behalf of patient welfare into paid employees would also be clearer.

Imagine Walmart were to change its name to "St. Mary's Emporium" Would it modify your perception of their business? I think it would. It would cause many people to believe that maybe their work was, at least in part, charitable and being done for the public welfare. But Walmart makes such pretense--they are in business for profit, just like all businesses.

It's time for the pretense to be dropped. Hospitals are cut-throat profit-seeking operations, operating under the guise of charitable, tax-free institutions. It's the farthest thing from the truth.

American Heart Association stamp of approval

The American Heart Association (AHA) has a program called the Heart-Check Mark, an "approval" process that permits a food manufacturer to affix the AHA logo and stamp of approval on various food products.

A company simply makes application to the AHA. The application and product details are reviewed and then approved or turned down.

To date, 106 companies have obtained the AHA stamp of approval on 768 products. What kinds of products are on the approved list? Here's a sample:

--Honey Bunches of Oats

--Kellogg's Frosted Mini-Wheats

--Cocoa Puffs cereal

--Cookie Crisp cereal ("The great taste of chocolate chips in every bite!")


There are 764 others. If you doubt this, just go to the store and take a look at the product containers.

What the heck is going on here? Most of us with any judgment know that these products are pure sugar. They may contain "no more" than 15-40 grams sugar per sugar, but the principal products--corn, wheat, fructose--mean that these products are, in effect, nearly pure sugar. Yet they carry the AHA stamp of approval.

What do products like this cause? It's a long list but the major effects include:

--Obesity

--Diabetes

--Drop in HDL

--Rise in triglycerides

--Small LDL particles

--Heightened inflammation (i.e., C-reactive protein)

--Mental cloudiness


Need I go on? Why are products like these and many others deserving of the AHA heart-check approval? Because they lack high fat and saturated fat (3.0 grams, 1.0 grams respectively, by AHA criteria). In other words, just lacking these ingredients means that, to the AHA, they qualify as "heart healthy."

By that same line of reasoning, many candy bars are "heart healthy", as are many cookies and cupcakes.

What's the reason behind this extraordinary absurdity? Is the AHA stupid?

There may be many reasons, but one very suspicious fact becomes immediately obvious when you realize these endorsements product a substantial revenue source for the AHA, since companies must pay for the right to use the heart-check approval mark. Also, just look at the major contributors (millions of dollars) to the AHA: ConAgra, General Mills, Kraft, etc.) You get the picture.

Does this make the AHA evil? Not necessarily. But it seriously erodes credibility. it also should make you very leery of any advice that comes from such an agency that is reluctant to bite the food manufacturer hands that feed it.

In my view, we simply cannot rely on the AHA for genuine, unbiased heart health advice.

"Your heart scan score means nothing"

Charles was visibly confused.

He'd gotten his CT heart scan after hearing one of the local scan center's ads on the radio. His score 2773, obviously in the 99th percentile for any age.

"Do you think the score means anything? My primary doctor said that it was meaningless because it was all in the deep wall of the artery. He said that it has nothing to do with risk for heart attack. As long as I feel good, he says don't do anything."

What exactly did his doctor mean, in the "deep wall of the artery"?

What the doctor is referring to is the fact that some people with a long history (many years) of diabetes or kidney failure (also for many years) tend to develop calcium deposits in the media, or muscular layer of arteries. The media is the tissue thin layer just below the intima, the most inner layer of arteries that we usually associate with atherosclerotic plaque and the layer that is most prone to calcium accumulation that we score on heart scans.

Aging, generally into your late 70s, 80s, and onwards, also increases the likelihood of medial calcification. Lastly, longstanding deficiency of vitamin D encourages medial calcification.

Is there any way to distinguish intimal vs medial calcification on a heart scan? No, there is not. Having read many thousands of CT heart scans, I can tell you that there is no practical way in 2007 to tell the difference.

Then how did this doctor "know" that Charles' calcium was "deep walled" or medial? Simple: He didn't. This was yet another example of ignorance based on old thinking. Unfortunately, he did Charles a serious disservice by dismissing his heart scan score that predicted a 25% per year risk for heart attack.

Interestingly, whether calcium is intimal as in atherosclerotic plaque, or medial, both are strongly associated with risk for heart attack. In other words, if calcium is confined to the intima, heart disease risk is present. If calcium is limited to the media, risk is still present.

In all practicality, the only difference we make of the intima vs. media argument (that is, when the distinction has been made by some other means like intracoronary ultrasound, the test that is truly necessary to distinguish the two patterns) is that medial calcification may be more powerfully related to vitamin D deficiency. Thus, someone with heavy medial calcification may require closer attention to maintaining a perfect year-round blood level of 25-OH-vitamin D3. But that's the only practical difference.

Vitamin D toxicity?

"My primary care doctor said to stop the vitamin D because it's toxic. So I stopped it and I just take a multivitamin. He said that a multivitamin and two glasses of milk a day was all I needed."

So proclaimed Eleanor to me. This happens around once every week by doctors frightened of the vitamin D.

So I reminded Eleanor that, before starting vitamin D supplementation, her blood level of 25-OH-vitamin D3 had been 17 ng/ml--severe deficiency.

On 4000 units per day (oil-based gelcap), her blood level had been 37 ng/ml--still deficient, below the desirable range of 50-60 ng/ml. That's the dose Eleanor's doctor had declared "toxic."

When exactly does deficiency develop? There's not full agreement on this, but Dr. Michael Holick of Boston University, among the most experienced and insightful authorities on vitamin D, states that toxicity is more likely when blood levels exceed 150 ng/ml (Nutr Clin Pract. 2007 Jun;22(3):297-304).

In other words, Eleanor and her doctor should not be concerned with toxicity, but with the persistent levels of deficiency she is suffering.

Some authorities call the behavior of vitamin D "bi-phasic": Deficiency is toxic, excessive levels are toxic. We're really just trying to achieve a middle ground in vitamin D levels that are above deficiency but below toxicity.

In reality, deficiency is exceptionally common. In fact, it's the rule around here (northern U.S.), with >95% of everybody we check severely deficient in winter, mildly-moderately deficient in summer. Very few people approach normal levels year round without supplementation.

Toxicity, on the other hand, is exceedingly rare. I have seen it once in a woman who was taking a toxic dose of 50,000 units a day on the instructions of her (mis-guided) doctor. Thankfully, no ill-effects developed from this little "experiment."

So, it's not toxicity that is the overwhelmingly common worry, but deficiency, severe and sustained.

Non-profit hospitals

Take a look at your local hospital and you're likely to notice several curious things:

1) It is likely non-profit, meaning it enjoys a non-profit status with the Internal Revenue Service and enjoys the tax benefits of not paying taxes on profits. This provides an advantage to tax-protected hospitals. 70% or more of hospitals in the U.S. are "non-profit."

2) Non-profit or no, many hospitals operate under the guise of a religious affiliation, e.g., St. Mary's Hospital, Trinity Hospital, All Saints', Jewish Hospital, etc.

3) Executives in non-profit hospitals can make capitalistic salaries. One CEO of a Milwaukee hospital took home $3.7 million dollars in salary last year. That's not including the very substantial perks and business interests in the spin-off businesses the hospital owns, including pharmacies, drug and medical device disitributors, even a venture capital division. "Non-profit" does not have to mean that executives within the operation can't benefit handsomely.

That same hospital system spends over $10 million dollars in a year in local marketing for TV ads, print advertising, etc. Ads are slick and professionally produced.

Make no bones about it: These are "non-profit" for tax purposes only . They are for-profit in every other sense of the phrase, including rich rewards for the insiders.

Guess how those fat executive salaries and large marketing budgets are paid for? That's right: the 12-inch incision in your chest; the four stents, defibrillator, and repeated nuclear stress tests; the revolving door of hospitalization after hospitalization that typifies the "heart patient" experience.

See the hospital for what it is: In the 21st century, it is no longer a charitable operation worthy of your volunteer time and donations. It is a business no different than Home Depot, IBM, or--Enron. Yes, they do perform needed services, as well. But the perverse equation that often determines who needs hospitalization and who doesn't, who needs a heart procedure and who doesn't, is not always based on necessity but on financial return. Just ask the CEO.

What's the best lipoprotein test?

This is a frequent question from Track Your Plaque Members and others interested in improving their heart disease prevention program beyond that of simple-minded cholesterol testing.

I obtain lipoprotein testing every day on patients. I can tell you with the confidence of having done thousands of these tests that plain, old-fashioned cholesterol testing is like relying on riding a scooter to work compared to an 8-cylinder modern automobile. The scooter might get you there, but any rain, snow, or long distance to travel and you can just forget it.

All too often, lipoprotein testing uncovers abnormalities that standard cholesterol testing simply fails to uncover.

So, among the various lipoprotein tests available, which is best?


There are three commercial tests available today:

1) Gel electropheresis (GGE)--often known by its "brand" name as the Berkeley lipoprotein profile, after Berkeley HeartLabs. GGE uses a gel with an electric field applied to cause lipoproteins to migrate, based on particle size and charge.

2) Vertical auto-profile (VAP)--a form of centrifugation, or high-speed spinning of blood plasma to separate lipoprotein particles.

3) Nuclear magnetic resonance (NMR)--the idea of putting plasma in an NMR (also known as MRI) device to characterize blood proteins.

All three tests do an excellent job. All are competitively priced. All have validating data--lots of it--to justify their broad use (though health insurers, in their vast wisdom, would still have you believe that the tests are "experimental").

But is one better?

Having done many of all three (though least of VAP), I am partial to Liposcience's NMR. (By the way, I receive no fees from Liposcience to use their test, nor to promote it in any way.)

I believe NMR is superior in a few ways:

1) I believe that the LDL particle number is the best way to truly quantify LDL, better than apoprotein B and "direct" LDL.

2) It provides what I believe to be more accurate small LDL measures.

3) It provides intermediate-density lipoprotein (IDL), a post-prandial, or after-eating, measure not available on the other two.

Perhaps I'm biased because I use the NMR most frequently. But I've used it because I felt it yielded superior, more clinically believable, data.

In truth, all three laboratories do an excellent job and you'd be served fine by obtaining any of the three. But my heart goes to NMR.

Vitamin K2, aspirin, fish oil and blood thinning

An interesting question came up from one of our Track Your Plaque Members on the Forum.

"I am now taking 9 mg of vitamin K1 and 1000 mcg of K2.

Does taking this supplement with this much K1 have a counteracting effect on the thinning/anticlotting properties of aspirin and fish oil that I also take?"


Great question (along with lots of other greater discussions we have on the Forum.)

The answer: Vitamin K should have no effect on the platelet-blocking effects of aspirin or fish oil. The majority of blood clot inhibiting effects of aspirin and fish oil arise from their ability to keep blood platelets from "clumping" (just like the TV commercials for Plavix).

Vitamin K, on the other hand, participates in the liver production of blood clotting factors (like II, VII, IX, and X, among others for you curious ones).

Thus, vitamin K-dependent clotting factors and platelet-blocking are two separate pathways to forming blood clots. Some of us refer to the difference as "red clots" from the vitamin K pathway and "white clots" from the platelet pathway, since they really do have this different physical appearance.

The vitamin K2 conversation, like that about vitamin D, is fascinating for its potential to provide the missing link between the tightly-tied fortunes of bone health and atherosclerosis. Why is someone with a high CT heart scan score far more likely to have osteoporosis? Vitamin D and K2 deficiency may provide the missing link for many people.

"Drug no cure for gluttony"

That's the headline I'd like to see associated with rosiglitazone, brand name Avandia.

The recent negative press, whether deserved or not, surrounding the prescription drug rosiglitazone for pre-diabetes and diabetes highlights the fact that drugs never--never--substitute for what we can achieve with lifestyle changes.

Typically, rosiglitazone reduces blood sugar a few milligrams, reduces C-reactive protein, and very modestly reduces triglycerides and its associated evil lipoprotein friends. It also causes an average weight gain of 8 lb in the first year of use.

What will weight loss achieve, especially if accomplished through dramatic reduction or elimination of processed carbohydrates and wheat products, along with fish oil supplementation, vitamin D normalization, and exercise? Extraordinary benefits, far superior to what is achievable with this drug. In fact, while rosiglitazone is a Band-Aid for this process, the lifestyle changes can represent a cure in many or most instances.

It should come as no surprise that a drug that does nothing more than increase sensitivity to insulin cannot erase the devastating effects of an unhealthy life. Take rosiglitazone but neglect exercise, don't bother with vitamin D, indulge in pretzels and breakfast cereals, gain more weight . . . It serves the drug company's agenda better than it serves health.

Rosiglitazone not so rosy?

Dr. Steve Nissen of the Cleveland Clinic published a study that suggests that the pre-diabetes and diabetes drug, rosiglitazone, may increase likelihood of heart attack by 43%.

I say "suggests" because the analysis was something called a "meta-analysis", a re-examination of data obtained by pooling unrelated studies and reanalyzing the data. Strengths of this sort of analysis: Sometimes trends that are not evident in smaller studies finally become evident in the larger numbers of participants obtained through pooling of data. Downside: Any statistician will tell you that a meta-analysis can only suggest an association, it cannot prove it.

Nonetheless, we are talking about people's lives. As they say, if you are taking this drug, also known by the brand name, Avandia, then talk to your doctor. I think that this is sound advice, as there are a number of factors to weigh in decision making. For instance, how far along the diabetic path are you? Have you had negative experiences with other agents?

It will, unfortunately, be months to years before confirmatory evidence on this question become available. In the meantime, Nissen will accuse the drug industry of pushing drugs through the FDA approval process without full safety data. GlaxoSmithKline, the manufacturer of Avandia, will counter with claims of weak data, the existing trials not confirming Nissen's findings, etc. We've seen it before.

My take on this is to step back and look at the broad picture. Do we need yet another reason to say that it's far better to maintain normal body weight, dramatically reduce reliance on processed carbohydrates and wheat, exercise, and following other insulin-sensitizing strategies, rather than rely on insulin-sensitizing drugs? (That's what rosiglitazone is supposed to do.) Metabolic syndrome, also known as pre-diabetes, or diabetes is present to various degrees in two thirds of all adults I meet. Nearly all of it is self-inflicted. Nearly all of it is curable with the above lifestyle strategies if undertaken early enough in the process.

A 190 lb, 5 foot 2 inch woman, or a 220 lb, 5 foot 10 inch man, both of whom are surprised that they have pre-diabetes really need to get a grip on reality and health. To me, it's no surprise that drugs do not reverse all the nasty manifestations of lifestyle gone berserk. It should also come as no surprise that the complex, chaotic physiologic mess created by metabolic syndrome and pre-diabetes is not perfectly managed by adding one drug.

The lipid distorting effects of weight loss

Roger experienced a near-fatal heart attack 6 years ago. He survived thanks to the quick action of bystanders who initiated CPR and called 911. An emergency catheterization was performed and a stent implanted into the closed right coronary artery. But that's not why I tell Roger's story.

Since then, Roger has become comfortable with the idea that he has heart disease. His initial commitment to good nutrition and exercise has waned, as it often does in us distractable humans. So Roger gained about 30 lbs through a long winter, inactivity, eating frozen dinners, and the cookies and baked goodies his daughters made him.

As a result of the weight gain and inactivity, Roger's HDL dropped to 32 mg/dl, triglycerides rose to 211 mg/dl, blood sugar crept up into the pre-diabetic range of 116 mg/dl. Undoubtedly, small LDL was out of control beneath the surface. His tummy reflected the weight gain, flaccid and overhanging his belt.

I read Roger the riot act. I reminded him of what he had experienced and nearly didn't survive. Weight loss and a re-invigoration of his nutrition and exercise efforts was going to be crucial.

Roger listened and took it to heart. Over three months, he lost 24 lbs, a phenomenal result. However, his repeat lipid panel showed an HDL of 28 mg/dl, triglycerides 234 mg/dl, blood sugar unchanged.

"I don't get it! I lose all this weight and the number get worse?!" Roger was understandably upset after his enormous effort.

I told Roger that after a profound weight loss, lipids can go berserk for up to two months after weight has stabilized. Typically, HDL drops and triglycerides rise--the opposite of what we want. But wait another two or so months after weight has stabilized and the numbers begin to look beautiful.

Why does this crazy effect happen? I really don't know and I've never heard a satisfactory explanation for it. But it is very real and quite predictable.

The lesson: after a substantial weight loss, be patient. Check your lipid numbers too soon and you might be confused or disappointed. If you do check them, bear in mind that additional time may need to pass before you see the weight loss fully reflected.

Cholesterol reduction and wheat

In my previous post, Identical twins and the explosive influence of weight , we witnessed an excellent example of the profound influence of food choices and weight control on lipoproteins. The heavier twin among these 35-year old male twins (Steve) had an LDL particle number over two-fold higher than his more slender counterpart (Alfred).

The heavier twin, Steve, got here through numerous and longstanding dietary excesses: fast foods, saturated fats, sweets, processed foods. The conventional answer to Steve's lipid dilemma would be to modestly reduce his reliance on saturated fat, exercise, and limit snacks.

How far would that get Steve? Not very far at all. With regards to his high LDL particle number of 2256 nmol/l (representing an "effective" LDL cholesterol of around 225 mg/dl), it would be reduced a little, perhaps 10%.

Notice, however, that 72% of all Steve's LDL particles are small (1639/2256). This is the pattern that responds dramatically to a sharp reduction in processed carbohydrates, especially wheat-containing products.

If Steve were to eliminate all wheat products--all breads, breakfast cereals, pretzels, cookies, cakes, pasta, crackers--LDL particle number will drop dramatically, perhaps 50%, often more depending on the magnitude of weight loss. Small LDL will respond most obviously and will be sharply reduced, perhaps disappear. Incidentally, these changes might not be well reflected by the conventional calculated LDL cholesterol, since small LDL particles are well-concealed by standard measures.

Reducing corn products, white and brown rice, and potatoes would also add to the effect. But, in 2007, wheat products represent 90% of the problem for the majority of people. Reducing or eliminating wheat therefore yields the biggest effect by a long shot.

Steve therefore represents an excellent example of how reducing processed carbohydrates, esp. wheat-containing products, can yield an unexpected and paradoxical reduction in LDL cholesterol as evidenced by the highly accurate LDL particle number (or apoprotein B). Reducing saturated fat sources also helps, but it certainly will not yield the kind of results most people need. You've got to be smarter than the simple-minded conventional advice.
