More catheterizations would make me happy!

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

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

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

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

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

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

"I hate fish oil!"

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

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

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

Helpful strategies include:

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

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

Sudden death in athletes

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



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

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

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

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

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

My heart scan was wrong!



Tom came into the office ready for a confrontation.

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

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

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

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

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

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

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

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

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

Fish oil in the news



Hooray for the New York Times. They ran an article pointing out the miserable and inexcusable failure of American physicians to use fish oil after heart attack.

“It is clearly recommended in international guidelines,” said Dr. Massimo Santini, the hospital’s chief of cardiology, who added that it would be considered tantamount to malpractice in Italy to omit the drug.

...in the United States, heart attack victims are not generally given omega-3 fatty acids, even as they are routinely offered more expensive and invasive treatments, like pills to lower cholesterol or implantable defibrillators. Prescription fish oil, sold under the brand name Omacor, is not even approved by the Food and Drug Administration for use in heart patients."

The article focuses on the use of fish oil only after heart attack and doesn't tackle the larger issue of how fish oil is crucial for coronary disease in general. Of course, the article doesn't address the extraordinary effects of fish oil on lipoproteins, particularly triglyceride-containing varieties like VLDL and the postprandial (after-eating) intermediate-density lipoprotein (IDL).

It also talks about prescription fish oil and just glosses over fish oil as a nutritional supplement. I know of few reasons to use the prescription form. More than 90% of the time, nutritional sources of fish oil do the trick. (That is, fish oil capsule supplements, not just eating fish which doesn't provide enough for coronary plaque reduction or control.)

Occasionally, I'll meet someone who has a severe hypertriglyceridemia (very high triglycerides), or is a Apo E 2/2 homozygote (very rare). These special instances may, indeed, do better using prescription fish oil, since it is more concentrated--one prescription capsule providing the same omega-3 fatty acid content as three conventional capsules (1000 mg fish oil, 300 mg EPA+DHA).


But for most of us, the standard fish oil supplement you buy at the health food store or department store does just fine. If you read about the impurity of fish oil supplements (likely prompted by the manufacturer of Omacor, prescription fish oil), refer to the studies by Consumer Reports and Consumer Labs, both of which found no mercury or pesticide residues in dozens of fish oil preparations tested.

Look on the bright side. The conversation is growing. Fish oil, whether prescription or my favorite, Sam's Club Members' Mark brand, is a fabulously effective supplement with benefits that, in nearly all cases, exceeds the benefits of drugs.

Fish oil is an absolute requirement for your Track Your Plaque program and for you to hope to achieve control or reduction of your heart scan score.

Nutritional approaches to homocysteine reduction


For an in-depth discussion of nutritional approaches to homocysteine reduction, see my new article, Nutritional Therapies for Managing Homocysteine , in the most recent issue of Life Extension magazine. You'll find it at:

http://www.lef.org/magazine/mag2006/oct2006_report_homocysteine_01.htm

The report contains a detailed discussion of how to use foods to control homocysteine levels. Though I'm not a homocysteine-crazed fanatic like Life Extension publisher, William Falloon, I still there's some interesting aspects of homocysteine metabolism that need to be explored. I also think there's some genuine benefit to reducing homocystine, preferably with foods, secondarily with supplements.

Also see our recent update on homocysteine on the www.cureality.com website at:
http://www.cureality.com/library/fl_01-006homocysteine.asp

In the update, we tried to make sense of what the new studies on homocysteine treatment, NORVIT and HOPE-2, tell us in light of all the other studies on homocysteine that preceded them.

The American Heart Association diet guarantees you get heart disease!

Perhaps I stated that too strongly.

But the fact remains: the diet advocated by the American Heart Association is awful. The foods endorsed by their approach have no place on a list of healthy foods. Yes, you will find vegetables and fruits, etc.. But you will also find that the 2006 American Heart Association Diet and Lifestyle Recommendations dance around the issue of what foods to avoid. There's no explicit mention of how, for instance, common foods like Shredded Wheat cereal, ketchup, low-fat salad dressings, etc, among thousands of others, should be avoided.

No matter how you time your meals, mix them, combine proteins, fats, and carbohydrates, etc., you simply cannot squeeze health out of products like breakfast cereals, instant mashed potatoes, dried soup mixes, wheat crackers, etc. Yet these are the sorts of foods that are implicitly allowable in the Heart Association's diet program.

You can obtain a little insight into the motivations behind the diet design by looking at the Heart Association's Annual Report list of major supporters:

--ACH Food Companies--maker of Mazola margarine and corn oil. A contributor of between $500,000 and $999,000 to the Heart Association.

--ConAgra Foods--You know them as Chef BoyArdee, Peter Pan peanut butter, Kid Cuisine (pizza, macaroni and cheese). ConAgra contributed between $500,000 and $999,000 to the Heart Association.

--Archer Daniels Midland--Huge worldwide supplier of wheat flours, high-fructose corn syrup, and basic ingredients for manufacture of soft drinks, candies, and baked foods. ADM contributed between $1-4.9 million dollars to the American Heart Association.

Of course, the Heart Association provides many hugely positive services like funding research. But, on many official statements, you need to read between the lines. The Heart Association is funded by industry: medical device makers, drug makers, food manufacturers. Yes, some is contributed in the interest of health. But you can be sure that lots of money is also contributed in the hope of protecting specific commercial interests. Many of those decisions are made behind closed doors or on the golf course.

Be skeptical. Just because the Heart Association diet is a Casper Milquetoast version of a health program, it does not mean that you have to subscribe to their watered-down, politically correct, and downright useless nutrition recommendations.

I'm just right!

Ben is an energetic 45-year old entrepreneur. He started his own security alarm company and has, with tremendous hard work and long hours, built it into a successful local business. Despite his long hours, he found time to coach his son's football team and help with raising his 3 kids.

Ben's life took a detour when he had urgent bypass surgery at age 39. Just three years later, the chest pains and fatigue he'd experienced before bypass returned. Another heart catheterization revealed that all of his bypass grafts except one had closed. Three stents were implanted to salvage his original coronary arteries.

That's when I met Ben. Shockingly (perhaps I should know by now!), Ben was taking Lipitor and had been advised to follow a low-fat diet. That was the full extent of his heart disease prevention program. The burning question that I wanted answered was "Why did a 39-year old man have heart disease?".

Our analysis uncovered a smorgasbord of hidden patterns. You name it, Ben had it: postprandial (after-eating) patterns like IDL, low HDL, and, most notably, small LDL and lipoprotein(a). That's why Ben had heart disease as a 39-year old man--plain and simple.

We proceeded to correct all of his patterns. But the one aspect of his program that he struggled with: weight. At 5 ft 9 inches, Ben started at 285 lbs before bypass. He did manage to get to 270 after his surgery. I told him that, if he was going to get full control of his small LDL pattern, he needed to get to <210 lbs, perhaps even lower. Without substantial weight loss, he would never seize full control over coronary plaque.

Ben was satisfied that we had identified the hidden causes of his heart disease. But he remained skeptical that that magnitude of weight loss was necessary. Built like a football player, he looked stocky but not outright fat. He got down to 240 lbs but then he decided that he looked too skinny and just went right back up to 250-260 in weight.

At a weight of 250, this puts Ben's BMI (body mass index) at around 37, way over the cut-off of 30 for obesity. Now, the BMI can be misleading in people with larger frames and more muscle. But Ben undeniably had a generous abdomen, encasing the visceral fat that drives small LDL.

Unfortunately, Ben remained skeptical until I put three more stents into his right coronary artery last evening.

Small LDL is a powerful activator of lipoprotein(a). In other words, there's something peculiarly evil about the combination of small LDL and lipoprotein(a) that brings out the worst in both. You can't correct just one or the other. You've got to correct both. Don't learn this lesson the hard way.

I think (hope) that Ben is on track to get to around 200 lbs.

Prevention: Bad news in bits and pieces

Jan clearly did not want to talk about her heart scan. Her score of 502 came as a shock to her. After all, she'd survived breast cancer just a year earlier, having been through dozens of radiation treatments, chemotherapy, not the mention the emotional upheaval.

Now I was telling Jan that she had a very high heart scan score with a heart attack risk of 5% per year. Then we got to her lipoprotein patterns: Jan had several striking abnormalities, including a misleading LDL cholesterol that underestimated her true LDL by nearly 100% (LDL particle number), small LDL, and the dreaded lipoprotein(a).

"I can't handle this! Why did I get the stupid scan in the first place?!"

Giving her a chance to collect her emotions, I discussed how, even though this business can be frightening, it's far--FAR--better than the alternative: heart attack at 3 am, rush to the hospital, stents, bypass surgery, etc. Or, death for the >30% of people who don't make it to the hospital in time.

That's why I often tell people that prevention of disease is bad news in bits and pieces. But it's a lot more manageable this way. Coronary plaque is a controllable process. You don't have much control in the midst of a heart attack.

A second chance

Stewart had a CT heart scan in 2004. Score: 475.

As always in the Track Your Plaque program, Stewart had his lipoproteins assessed. Among his patterns were LDL 157 mg/dl, severe small LDL, and the (post-prandial, or after-eating) IDL. Stewart was also "pre-diabetic" with a blood sugar of 123 mg/dl. Blood pressure was also a major issue. Although initially concerned, life and distractions got in the way, and Stewart's attentions drifted away.

Two years of a lackadaisical effort and Stewart's heart scan score was 600, a 26% increase. Not as bad as it could have been doing nothing (i.e., 30% per year), but still far from great. But, even with the increase in score, we still really didn't get Stewart's attention. He went about his business with a very lax dietary program, overindulging in breads, crackers, goodies, hot dogs, etc., and following a virtually non-existent exercise program except for playing golf once or twice a week.

Unfortunately, Stewart started having pains in his chest with very minimal efforts like climbing a single flight of stairs. His stress test proved abnormal. Stewart then received a stent in his left anterior descending coronary and another in his circumflex. His right coronary artery had a 40-50% blockage, close to requiring a stent.

I stressed to Stewart that this had been preventable. Should motivation remain unchanged, the next step would be bypass surgery.

I think I finally succeeded in getting Stewart's attention. He found the prospect of a bypass operation a lot more concrete than the idea of progression or regression of coronary plaque. So Stewart is being given a second chance. Unfortunately, we will no longer be able to track Stewart's plaque very effectively, since two of three arteries now contain stents, and only the right coronary remains scorable.

I hope Stewart succeeds. But I sure wish he had done this earlier. He had realistic hopes of never requiring stents or bypass surgery.

Learn from Stewart's mistakes. Attention to your program requires vigilance. You can't ignore the causes of your coronary plaque for any length of time without it catching up to you. But seize your first and best chance.

Homocysteine and coronary plaque

If you’ve watched the news over the past year, you know that doubt has been cast over the idea that reducing homocysteine blood levels with high doses of B vitamins (B6, B12, and folic acid, or B9) results in reduced risk for heart attack.

Is the homocysteine concept dead? Shall we empty our bottles of costly B vitamins into the trash and move on?

I don’t think so. As detailed in one of our Track Your Plaque Special Reports from a few months ago, I think the homocysteine issue still deserves lots of respect and further investigation. After all, hundreds of clinical studies have connected higher homocysteine levels with greater risk for heart disease, stroke, and aneurysm. Numerous studies, for example, have repeatedly and consistently demonstrated a tripling of heart attack risk when homocysteine levels exceed 14 ?mol/l. Can we dismiss this association because several more recent studies—NORVIT, HOPE, and VISP—suggested that, when starting homocysteine levels are 12.5, that B vitamin supplementation does not reduce heart attack risk?

I think there’s lots more to know about the homocysteine connection. That said, I have never seen a patient who I thought had heart disease strictly because homocysteine was increased.

I believe that we can at least use homocysteine as an index of lifestyle: the higher the homocysteine, the poorer the diet, or the less effective the absorption of B vitamins (especially vitamins B12 and folic acid). Homocysteine levels of <9 micromol/l suggest both adequate intake and absorption of these B vitamins.

If homocysteine is tightly connected with risk for heart disease, yet supplementation of B vitamins fails to reduce risk, might there be another means of connection? Or, could both homocysteine and heart disease be connected in some way that has nothing to do with B vitamins?

Don’t close the book on homocysteine. Just because conventional experience fails to draw connection does not necessarily mean that none exists. If it’s any consolation, taking B vitamins has been correlated with better memory, concentration, and other health benefits, even if no reduction in heart disease develops.

Big heart scan scores drop

High heart scan scores of, say, greater than 1000 are more difficult to reduce than lower scores.

I learned this lesson early in the experience of trying to drop scores. In the first few years of trying to drop scores, I saw relatively modest scores of 20, 50, or 100 drop readily, even when the usual targets were not fully achieved, and even before the incorporation of some of the more exciting recent additions to the Track Your Plaque program, like vitamin D.

But big scores of 1000, 2000, or 3000 are a tougher nut to crack. In the first few years, what I usually saw was a slowing , or "deceleration," of growth from the expected rate of annual score increase of 30% that would continue for a year or two, followed by zero change. In the first year of effort, for example, a score increase of 18% was common. 10% was common in year two, then finally zero change in year three. Somehow, the more plaque you begin with, the more "momentum" in growth is present and the longer it takes to stop it. Kind of like stopping a compact car versus stopping a freight train.

But more recently, I'm seeing faster drops. Today, Charlie came to the office to discuss his second heart scan. 18 months earlier, Charlie's first scan showed a score of 3,112, high by anybody's standard.

His repeat score: 3,048. While the drop is relatively small on a percentage basis and may even fall within the expected rate of error for heart scans (which tends to be <2% at this high a score), I told Charlie that it still represented a huge success. Not only did he not increase his score by the expected 30% per year, he also brought a charging locomotive to a rapid stop.

Next year, Charlie is targeting a big drop. Given the tools he now has available, I'm optimistic that he will succeed.

Watch for the Track Your Plaque May, 2007 Newsletter in which we will detail Charlie's story further.

Does the American Heart Association diet reduce heart disease?

If you have a heart attack and land in the hospital where, invariably, you will have a heart procedure. Or, if you get a stent or coronary bypass operation, sometime before your discharge from the hospital, a well-meaning hospital staff dietitian will provide instruction in the American Heart Association (AHA) diet.

Does this diet reduce the risk of heart disease?

The answer depends on where you start. If you begin with a conventional American diet that is enormously influenced by convenience, food manufacturers like Nabisco, General Mills, Quaker Oats, ADM, and Cargill, or food distributors like McDonald’s, Pizza Hut, and Taco Bell, then the American Heart Association diet is indeed an improvement. But just a small one. If LDL cholesterol is the yardstick, the average reduction in LDL is between 10 and 15 mg/dl. This is the same amount of change you’d experience by adding 1 tablespoon of oat bran to your diet. Hardly worth boasting about. HDL, triglycerides, blood glucose, and body weight do not change.

The diet could be substantially better. After all, it’s become common knowledge that other diets, such as the so-called Mediterranean diet, the South Beach Diet, and similar broad projects result in far greater changes than the AHA diet dispensed by your hospital and cardiologist. These diets more effectively reduce LDL, raise HDL, reduce triglycerides, reduce C-reactive protein, reduce blood pressure. Diets like South Beach also yield substantial weight loss and reversal of diabetic tendencies, with the magnitude of benefit dependent on the amount of weight lost.

Why this stubborn adherence to the outdated concepts articulated in the AHA diet? Cardiologists would argue that insufficient data has been generated to permit widespread application of these diets. They also differ on whether they really work. Of course, the majority remain ignorant and dismiss them as fad diets.

A little digging into the financial disclosures of the AHA suggests another, more malignant influence: who is paying the bills? Until recently, drug manufacturers were major contributors to the AHA. However, more recently AHA administrators have become sensitive to the public perception that they might be nothing more than a voice box for the drug industry. They have since limited contributions from the drug companies to 8% of annual charitable revenues.

The drug manufacturers have been replaced by the food industry. In addition to food manufacturers that make the cereals on your grocery shelf, it includes the multi-national conglomerates that produce unimaginable revenues and carry enormous political clout, like ADM and Cargill. Ever wonder how it is that Honey Nut Cheerios received a “Heart Healthy” endorsement from the AHA?

The AHA diet does not provide the answers we’re looking for, not even close. It is a perversion from an organization that has its strings pulled by industry. The answers to health will not come from the AHA, AMA, the American College of Cardiology, the American Hospital Association, and it won’t come from your doctor. It won’t come from a titillating report on the evening news or Good Morning America. It will come from collective and expanding wisdom placed directly into the hands of the public. It will be untainted by the temptation of drug industry dollars. It will not be dirtied by million dollar contributions, or the multi-million dollar behind-closed-doors lobbying of the food manufacturers. It will come from the truth relayed to the healthcare-consuming public. I hope you recognize it when you see it.

If you want a healthy diet for your heart, throw away the pamphlets from the AHA unless you are partial to bread, breakfast cereals, corn, and the supporters of their misguided nutritional advice.

Vitamin K2 and coronary plaque

The vitamin K2 story, though still preliminary, is becoming increasingly interesting from the perspective of CT heart score reduction.

The origin of this concept came from some unexpected observations. One, the observation that osteoporosis (lack of bone calcium that leads to fractures) arises from deficiency of vitamin K2. Two, deficiency of K2 leads to unrestrained calcium deposition in animal models, leading to heart attack in just weeks.

Vitamin K2 has been largely ignored for years, since the more widely understood K1 is rarely deficient. K1 deficiency can occur from prolonged antibiotic use, or from severe malnutrition. But deficiency in otherwise well people is very uncommon. Vitamin K2, however, may be a different story. Deficiency may be common.

The Rotterdam Heart Study of cheese-eating Dutch showed that greater K2 intakes resulted in a halving of heart attacks. Cheese (traditional varieties, not Velveeta or other make-believe cheese products) is a modest source of K2, as is the Japanese native food, natto. (If you've ever seen natto, I dare you to eat it. I have a pretty strong stomach and curiousity for food, but natto is the one thing I could not eat--it is truly horrible.)

The weight of evidence suggests that vitamin K2 supplementation may prove to be a useful addition to your coronary plaque control program. Clearly, more data are needed, particulary therapeutic obserations, i.e., observing people who take dose X of a K2 prepartion and tracking some feedback measure, e.g., bone density, CT heart scan score, "events" like heart attack, etc.

Nonetheless, the K2 story is clearly worth reading about, perhaps even considering supplementation. Please watch for the Special Report on the www.cureality.com website in the coming days.

Exercise and blood pressure

The media has gotten a hold of a case report from the University of Maryland describing a 51-year old physician who, despite being a long distance runner, had a high heart scan score.

An example of the report can be found at

Heart Disease In A Marathon Runner: Is Too Much Exercise A Bad Thing?

http://www.sciencedaily.com/releases/2007/03/070315091100.htm in Science Daily.



"The mystery was all the more intriguing because his resting blood pressure and fasting cholesterol levels, the usual measures of cardiovascular health, were in the normal range."


When this man was put on a treadmill for a stress test, his blood pressure skyrocketed from a normal 118/78 to 230/78--extremely high, even for exercise. The physicians reporting the case raised the question of whether long-distance running represents a risk for heart disease and if the high blood pressure with exercise is a contributor or cause of the high heart scan score.

These are phenomena we are very familiar with. We have stressed the importance of exercise blood pressure as a trigger for coronary plaque for years. While 230/78 is clearly too high, we find that any blood pressure over 170/80 with exercise adds to the fire and can trigger plaque growth.

However, I think it is absurd to suggest that marathon running itself is a trigger of coronary plaque. I think it is far more likely that the person described in the report had lipoprotein(a), a potent trigger for both exercise-induced hypertension and high CT heart scan scores in seemingly well people. He likely also suffered from a deficiency of vitamin D deficiency, another contributor. There's no need to indict exercise.

If you are in the Track Your Plaque program, you know that stress tests are of questionable helpfulness for the detection of hidden heart disease. But they are useful for assessment of blood pressure responses during exercise. If BP exceeds 170/80 at 10 mets (a measure of exercise effort achieved by walking 3.4 mph at a 14% grade for 3 minutes), then blood pressure may be a contributor to your heart scan score.

"Fish oil is stupid"

"Fish oil is a waste of time and money. It's stupid. Just stop it."

So a patient of mine was advised by another physician when he complained that he occasionally experienced a fishy aftertaste.

This attitude perplexes me. After all the confirmatory data that support the enormous health benefits of omega-3 fatty acid supplementation, including the 11,000 participant GISSI-Prevenzione Trial, you'd think this attitude would be history. What's a little fish aftertaste when heart attack risk is slashed 28%?

Perhaps the tendency to pooh-pooh fish oil is because it's available as a nutritional supplement. This shouldn't make fish oil appear inconsequential. Far from it.

If you witness the extraordinary power for fish oil to reduce triglycerides, you will be immediately convinced of its effectiveness. The ability of omega-3 fatty acids from fish to eliminate intermediate-density lipoprotein (IDL), the persistent abnormal lipoprotein which signals an inability to clear dietary fats from the blood, can also convince you. More than 90% of people with excessive IDL have it completely eliminated by 4000-6000 mg of fish oil (providing 1200-1800 mg EPA + DHA) per day.

The fact that fish oil is available as a prescription "medication," as well as an over-the-counter supplement, causes some physicians to dismiss the power of the supplemental form. This is nonsense. The over-the-counter form is every bit as effective as the prescription form.

The makers of prescription Omacor also make the claim that their preparation is safer and purer. That may be true, but I'd like to see independent verification from the FDA, USDA, or an unbiased organization like Consumer Reports before I accept their marketing as fact--particularly at $120 to $240 per month! If Omacor proves to contain substantially less mercury and pesticide residues, then that will need to be factored in. (Please note that both Consumer Reports and Consumer Labs measured no substantial mercury or pesticide residues in their analyses of 16 and 41 brands, respectively.)

I try to persuade my colleagues that the idea of taking supplements is a wonderful trend that allows people to express ownership of their own health. What people need is guidance, not salesmanship for a more expensive version, nor dismissal of nutritional preparations that actually possess considerable benefits.

More Vitamin D and HDL

I’m seeing more and more of it and I am convinced that there is a relationship: significant boosts in HDL cholesterol from vitamin D supplementation.

To my knowledge this remains an undescribed and uncharacterized phenomenon. There have been several observers over the last two decades who have noticed that total cholesterol shows a seasonal fluctuation: cholesterol goes up in fall and winter, down in spring and summer; year in, year out. This phenomenon was unexplained but makes perfect sense if you factor in vitamin D fluctuations from sun exposure.

I have come across no other substantiating evidence about fluctuations of HDL. But I am convinced that I am seeing it. Replace vitamin D to a blood level of 50 ng/ml, and HDL goes up if it is low to begin with. If HDL is high to begin with, say, 63 mg/dl, it doesn’t seem to change.

But, say, starting HDL is 36 mg/dl. You take niacin, 1000 mg; reduce high-glycemic index foods like breakfast cereals, breads, cookies, bagels, and other processed carbohydrate foods; exercise four days a week; add a glass of red wine a day; even add 2 oz of dark chocolate. You shed 15 lbs towards your ideal weight. After 6 months, HDL: 46 mg/dl. Better but hardly great.

Add vitamin D at a dose of, say, 4000-6000 units per day (oil-based gelcap, of course!), and re-check HDL two or three months later: 65 mg/dl.

I’ve seen it happen over and over. It doens't occur in everybody but occurs with such frequency that it’s hard to ignore or attribute to something else. What I’m not clear about is whether this effect only occurs in the presence of the other strategies we use to raise HDL, a “facilitating” effect, or whether this is an independent benefit of HDL that would occur regardless of whatever else you do. Time will help clarify.

We are tracking our experience to see if it holds up, how, and to what degree on a more formal basis. Until then, a rising HDL is yet another reason—-among many!-—to be absolutely certain your 25-OH-vitamin D3 level is at 50 ng/ml or greater.

How high is an ideal vitamin D blood level? If 50 ng is good, is 60 or 70 ng even better? Probably not, but there are no data. We have to wait and see. Unlike a drug that enjoys plentiful “dose-response” data, there are no such observations for vitamin D into this higher, though still “physiologic,” range.

Thin ice

How long can an industry built on ignorance and deception continue its practices in the new Information Age?

I don’t think it can for long. I talk to hospital administrators who believe that their source of competition is the hospital across town, battling for the same patients. I speak to my colleagues, the cardiologists, who believe that the current model is sustainable—take every willing body to the catheterization laboratory or operating room for heart procedures, the revenue-generating engine of income and expanding heart programs.

I speak to primary care physicians, who are dumbfounded and perplexed and have no idea which way things are going. They are trapped in a peculiar position: most have signed contracts and are employees of the hospital. They are legally bound to support the cardiologists who take anybody possible to the catheterization laboratory or direct patients to other profit-making procedures.

Much of this system depends on the willingness of the participant, meaning you and the health care seeking public. What happens when the truth comes out and disseminates widely through the thinking populace? What happens to hospitals and physicians and the vast structures they’ve built when the bottom drops out for 50% of their “market?

The proverbial cow manure will hit the fan. Upheavals in the medical industry will rival the changes that the automobile or telephone brought early in the last century. Cardiologists, immense hospital heart programs, and the vast economic infrastructure they spawned will go the way of stage coach manufacturers and the telegraph.

What form will the broad exposure of detailed information in health take? I’m not sure, but it will certainly come. The collaborative efforts that created the Linux operating system and have challenged the monopoly of Microsoft Windows, or the emergence of the extraordinary Wikipedia as a repository of human knowledge that dwarfs the venerated Encylopedia Brittanica, will eventually overtake the American medical system, the heart disease industry in particular.

If you base your future on the welfare of your local hospital or the manufacturers of stents, operating room equipment for heart bypass, or similar industries, watch out. The ice is thin. And as the spring warms the air around you, it gets thinner.

The Track Your Plaque program is our first step in broadcasting the message of self-empowerment in heart health care and an attempt to wrestle control away from the profit-seeking forces that dominate. As we grow, we not only hope to broadcast the message more widely, but expand the message to other areas of health. I predict that the collaborative, let’s-all-pitch-in-and-help spirit of the Information Age, “version 2.0,” will spark the change.

Vitamin D and cancer

Although this is a Blog about heart scans and heart disease, I came across a helpful video from Dr. Joseph Mercola about vitamin D and cancer that's worth viewing. Though I do not agree with many of Dr. Mercola's on-the-edge views, he does come up with some good thoughts and, in this instance, a useful educational tool about vitamin D.

You can view his video (which he claims crashed his server, due to the excessive demand for downloads) by cutting and pasting the address into your URL bar (above):

Also, for my many patients who I've directed to look in my Blog for Dr. Reinhold Vieth's webcast presentation on vitamin D, here's the address:

Perhaps I carry on too much about vitamin D. But I've come to respect this "nutrient" as among the most powerful strategies I've seen for dramatically improving control over coronary plaque growth as well as other aspects of health, as Drs. Mercola and Vieth eloquently detail.

Lipoprotein(a), menopause, and andropause

Lipoprotein(a) is a curious lipoprotein. Not only is it a genetic pattern with numerous variations, it is also one that shows a predictable age-dependent rise.

Women in particular are prone to this effect, men to a lesser degree. As we age, many hormones recede, particularly growth hormone, testosterone, the estrogens (estradiol, estriol, estrone), progesterone, and DHEA, among others. This is not a disease but the process of senescence, or aging.

When we're young, estrogens, testosterone, and DHEA all exert suppressive effects to keep lipoprotein(a), Lp(a), at bay. But as a woman proceeds through her pre-menopausal and menopausal years, and as a male passes through his fourth decade, there is an accelerated decline of these hormones. As a result, Lp(a) crawls out of its cave and starts to sniff around.

Typically, a woman might have a Lp(a) of 75 nmol/l (approximately 30 mg/dl) at age 38. Ten years later, at age 48, her Lp(a) might be 125 nmol/l (app. 50 mg/dl), all due to the decline of estrogens and DHEA. A parallel situation develops in males due to the drop in testosterone. For this reason, it may be necessary to re-check Lp(a) once after the fourth decade of life if you've had a level checked in your younger years.

This opens up some interesting therapeutic possibilities. If receding hormones are responsible for unleashing Lp(a), hormones can be replenished to reduce it. In males, this is relatively straightforward: supplement human testosterone and Lp(a) drops about 25%.

In women, however, it's a bit murkier, thanks to the negative experince reported using horse estrogens (AKA Premarin) in the HERS Trial and Women's Health Initiative. You'll recall that women who take horse estrogens and progestins (synthetic progesterone) do not experience less heart attack and develop a slightly increased risk of endometrial and breast cancer. There was, however, a poorly-publicized sub-study that showed that women with Lp(a) experience up to 50% fewer heart attacks on the horse/synthetic combination.

Wouldn't it be nice to have a large trial examining the safety/advisability of human estrogens and progesterone? To my knowledge, no such confident study in a significant number of women exists, since there's so little money to be made with human hormonal preparations.

For these reasons, we use lots of DHEA, generally at doses of 25 to 50 mg per day. It makes most people feel good, boosts energy modestly, increases muscle, and reduces Lp(a) up to 18% in women, a lesser quantity in men.
