How important is high blood pressure?


Control of blood pressure is crucial for coronary plaque control and stopping your heart scan score from increasing.

Dr. Mehmet Oz (of Oprah fame and a cardiac transplant surgeon at Columbia University) made graphic point of this on the ABC TV news show, 20/20, last evening on an episode called "Our Bodies: Myths, Lies, and Straight Talk". (See a summary on the ABC News 20/20 website at http://abcnews.go.com/2020/story?id=2109291&page=1)

Although I believe he somewhat overstated the case for hypertension (proclaiming "If you're going to remember one number, if you're going to focus and fixate on one number in your entire health profile, it better be your blood pressure"), he made the point that a blood pressure of 115/75 is what you should have for optimal health.

I couldn't agree more. Unfortunately, the old advice that desirable blood is 140/90 or less is absolutely wrong. At this level, we see flagrant increases in heart scan scores. We also progressive enlargement of the thoracic aorta, the large vessel that leaves the heart and branches to provide the major arteries of the body. Growth of the aorta to an aneurysm is also common at these formerly acceptable blood pressure. (The diameter of your aorta in the chest is an easily obtainable measure on your CT heart scan.)

The blood pressure you need for halting and reversing plaque growth on your heart scan is indeed 115/75 or less. (Not so low, however, that you're lightheaded.) This is the blood pressure that you were meant to have evolutionarily. It's also the blood pressure that helps tremendously in keeping your aorta from enlarging.

Is your doctor in cahoots with the hospital?

I got a call from a doctor about a patient we've seen in past.

"I've got Tricia in the office. She's been having some kind of chest and abdominal pain. I think it's esophageal reflux, but just to be safe I'm sending her to the hospital."

I advised this physician that, given Tricia's low heart scan score, she was unlikely to be having a coronary "event" like heart attack or unstable symptoms. It wasn't impossible, but just highly unlikely.

As the patient was without symptoms at the moment and had driven herself to his office, I offered to perform a stress test immediately. (Though stress tests are of limited usefulness in people without symptoms, they can be useful provocative maneuvers in people with symptoms of uncertain significance.)

The doctor declined. Tricia was, after all, in his office and he was responsible for any decisions despite any objections I voiced. Well, Tricia was directed by her doctor to go to a local hospital, though one with an especially notorious reputation for putting virtually anyone they can get their hands on through as many procedures as possible.

As you might guess, this doctor was closely associated with this hospital. He and his colleagues obtain incentives (or are penalized) if they do not generate revenue-producing procedures for the hospital.

So, guess what? Tricia ended up with several procedures, all of which yielded nothing--except $30,000 in revenues from Tricia's insurance company.

I harp on this deplorable state of affairs because it is utterly, painfully, and shamefully TRUE. Just look at the hospital and you'd better brace yourself for a series of tests that could cost you the equivalent of a nice 3 bedroom home. If they were truly necessary after the failure of preventive and other simple efforts, fine. But, all too often, they are driven by profit motives.

Could I have stopped this somehow from occurring? After all, Tricia was reasonably aware of the way we do things around here. I fear that even this failed to serve Tricia well. But I remain hopeful that, as we build broader awareness of these issues, that more and more people and physicians will stand up and refuse to tolerate the status quo.

Where is the Track Your Plaque program going?

I spend a lot of time worrying about how people can be helped to navigate through this program.

Take, for instance, the man in rural Texas who, while traveling in Dallas, got a heart scan on a whim. His score was 990. When he took the report back to his doctor, he got a smirk--and that's all. When he came to the Track Your Plaque program, he lacked a physician advocate to help him.

Or the woman from Florida who sought opinions from two reputable cardiologists for her heart scan score of 377. Both advised her that she needed a heart catheterization--despite her lack of symptoms, her 5-day-a-week exercise program, and normal stress test. She also lacks a physician advocate who acts on her behalf, helping her achieve success, rather than just churning her for money from hospital procedures.

For people like this and for others, I see the Track Your Plaque program evolving in several directions:

1) An online clinic--You enter and we take your "hand" and lead you step by step through the process, not only at the beginning, but over the months and years. This would help clear up some of the confusion and zigzags that some people experience trying to navigate through the program.

2) Develop physician and non-physician partners--The woman in Florida, for instance, could be referred to a doctor nearby who understands the program and is able to assist her. At present, this is virtually impossible because of the bias towards heart procedures, drugs as the sole treatment for heart disease risk, and the superficial physician-patient relationship. The majority of practicing physicians just don't understand the program despite the fact that it is based on sound clinical and experimental data. But it will in time.

Looking back, we've come a long way. I remember first having patients undergo heart scans 10 years ago. My colleagues laughed or called it "silly". The general public didn't know what they meant.

Now we're talking about how to broadcast the most powerful heart disease prevention program available in the world to a larger audience, but making it easier and more accessible. Mass media like Oprah's two hour-long spots helped, but we need to make the next leap. Not just identifying hidden heart disease to feed the hungry cardiovascular hospital procedure monster, but to educate/inform/empower the public on what to do with the scan once they've had it.

Who cares about triglycerides?

Walter's triglycerides were 231 mg. His LDL cholesterol was "favorable" at 111 mg, HDL likewise at 49 mg.

"Everything looks good," his doctor declared.

"Do you think the triglycerides are okay, too?" Walter asked.

"Well, the guidelines do say that triglycerides should be less than 150, but I believe you're close enough. Anyway, triglycerides don't really cause heart disease."


When I met Walter, I made several comments. First of all, in light of his heart scan score of 713, none of his numbers--HDL, LDL, or triglycerides-- were acceptable. But the triglycerides were glaringly and terribly too high.

Why? What exactly are triglycerides?

Triglycerides are a basic fat particle that, though they do not cause heart disease directly, trigger the formation of an array of abnormal lipoprotein particles in the blood that are among the most potent causes of heart disease known.

These abnormal lipoprotein particles include small LDL, VLDL, and IDL (intermediate-density lipoprotein--a really bad pattern). Excess triglycerides also cause HDL to drop. They also cause a distortion of HDL structure, causing the particles to become abnormally small. Small HDL is also useless HDL, unable to provide the protection that HDL is designed to do.

So Walter's elevated triglycerides are, in reality, a substantial red flag for an entire panel of abnormal particles that contribute to the growth of his coronary plaque.

So, if you get this kind of commentary on your triglycerides, ask for another opinion. (Track Your Plaque Members: Also see Triglycerides: Mother of meddlesome particles at http://www.cureality.com/library/fl_dp002triglycerides.asp.)

Total cholesterol and heart scans

Andy was fearful of heart disease in his life. At age 52, he'd already had four CT heart scans--one each year on or near his birthday.

Yet, when I looked at Andy's scans, his scores had been increasing 20-24% per year. Each and every score was greater by 20% or more over the previous.

So I asked Andy what steps he had taken to stop this relentless progression. "Well, I've always been real health conscious. But ever since my first scan, I really started sticking to a healthy diet, exercising nearly every day, and I take a bunch of supplements."

"What did your doctor advise?" I asked.

"Well, Dr. ---- said that nothing needed to be done, since my total cholesterol was always below 200."



Men's Health magazine's fabulous story about the folly of using total cholesterol to gauge heart disease risk.




Aaaauuuggghhh!! Wrong!

This man was, in fact, at rapidly escalating risk for heart attack. This rate of growth simply can't continue forever without igniting this bomb.

A total cholesterol below 200 is meaningless, as Andy's increasing coronary plaque proved. For instance, you can have a total cholesterol of 165 mg but with an HDL cholesterol of 27 mg. This would constitute very high risk for heart disease despite the low total cholesterol. The low HDL pattern is among the most common reasons for a misleading total cholesterol. Small LDL, high triglycerides, and lipoprotein (a) are other frequent reasons.

Andy, run the other way! Do not heed this doctor's advice! You need a solid answer to the question: Why exactly do I have coronary plaque in the first place?

Then, agree on a treatment program that corrects your specific causes.

Cardiologists out of touch

This weekend, I'm fulfilling some responsiblities I have every so often to some of the local hospitals. It gives me a chance to interact with many of my colleagues who are likewise "on call" for the weekend.

I tried to strike up several conversations with colleagues about how they were managing heart disease prevention. I received blank stares, puzzled looks, indifference. One colleague declared that 80 mg of Lipitor is all you need to know.

These same colleagues are the ones scrambling for the heart attack patients in the emergency room, climbing over one another for consultation in the hospital for patients with chest pain and heart failure. They're consumed with expanding the range of procedures they can perform.

Carotid stenting is hot. So is stenting of the leg arteries. Defibrillators have been a financial bonanza. Opportunities abound on how to add these procedures to a cardiologist's abilities.

But heart disease prevention? How about heart disease reversal?

Frankly, I'm embarassed by my colleagues' lack of interest. Imagine we had a cure for breast cancer--not a palliative therapy that just slows the disease down or prolongs life, but actually cures it once and for all. I would hope that all physicians and oncologists would learn how to accomplish this. What if instead they focused on learning new ways to remove breasts, administer new toxic chemotherapies, etc. but ignored the whole idea of cure?

This is what is happening with coronary plaque reversal. The answer is right in front of them, but the vast majority (99%) of cardiologists choose to ignore it. After all, prevention and reversal simply don't pay the bills.

That means that, in 2006, you simply cannot rely on your cardiologist to counsel you on how to achieve regression or reversal of coronary plaque. How about your internist, family physician, or primary care doctor? Well, they're busy doing pneumovax injections, Pap smears, managing knee and hip arthritis, low back pain, diarrhea, headaches, sinus infections and . . yes, dabbling in heart disease prevention.

And, for the most part, doing a miserable job of it. What you generally get echoes the drug manufacturers pitch: Take a statin drug, cut the fat in your diet.

Until the majority of doctors catch on, you're going to have to rely on sources like the Track Your Plaque program for better information.

What if your lipoproteins are perfect?



Sandy is a 56-year old woman--fit, slender, physically active, with no bad habits. A retired teacher, she has time to devote to her health. She bikes several days per week, mountain bikes, walks, and takes fitness classes. In short, she's the picture of perfect health.

Her heart scan score was not terribly impressive: 41. However, at her age, this modest score placed her in the 77th percentile. This suggested a heart attack risk of around 2-3% per year.

So we measured Sandy's lipoproteins. They were shockingly normal. In fact, Sandy is among the very rare person with absolutely no small LDL particles. All other patterns were just as favorable, including an HDL in the 80s.

This may seem like good news, but I find it disturbing. People are often initially upset by seeing multiple abnormal lipoprotein patterns. But lipoprotein abnormalities are the tools that we use to gain control over coronary plaque.

So what do we do when there are no abnormalities?

There are several issues to consider:

1) Your heart scan score reflects the sum total of your life up until that point. What if you were 20 lbs heavier 10 years earlier and your lipoproteins were abnormal during that period? Or you smoked until age 45 and quit? As helpful as they are, lipoproteins and related patterns are only a snapshot in time, unlike the heart scan score.

2) You have a vitamin D deficiency. This is unusual as a sole cause of coronary plaque. Much more commonly, it is a co-conspirator.

3) The heart scan is wrong--highly unlikely. Heart scans are actually quite easy, straightforward tests. (The only time this tends to happen is when scoring that appears in the circumflex coronary artery is actually in the nearby mitral valve. This really occurs only when there's very minimal calcium in the valve.)

4) There's a yet unidentified source of risk. Probably very rare but conceivable. For instance, there's an emerging sense that phopholipid patterns may prove to be coronary risks. One clinically available measure that we've not found very useful is phospholipase A2, known by the proprietary name "PLAC" test. (See http://www.plactest.com for more information from the manufacturer/distributor of the test.) But there's probably lots of others that may prove useful in future.

How often does it happen that someone fails to show any identifiable source for their coronary plaque? I can count the number of instances on two fingers--very unusual. (Thank goodness!)

Sandy's case is therefore quite unique. How should we approach her coronary plaque? In this unusual circumstance, lacking a cause, we tend to introduce therapies that may regress plaque independent of any measurable lipoprotein parameters. But that's a whole new conversation.

Fly to India for a bypass operation?


In the June 19, 2006 issue of People Magazine, there's an article called "The Doctor is in . . .INDIA". The report talks about how, with health care costs in the U.S. spiralling out of control, more and more Americans are leaving the country to have their procedure performed.

They tell the story of Mr. Carlo Gislimberti of New Mexico and cite these numbers:

Heart Surgery
Cost in U.S.: $200,000

Cost in India: $10,000


Mr. Gislimberti opted to have his coronary bypass operation in India for cost reasons.

But the People magazine report left out one other option: The Track Your Plaque program: $39.00

Do your part to save ballooning health care costs: Engage in a truly powerful program of heart disease prevention like the Track Your Plaque program. The cost difference is laughably huge. And you won't require a 12-inch chest incision.

Follow conventional guidelines and guess what? You're going to have a heart attack. Follow the American Heart Association diet and you'll have heart disease.

Cut to the chase. The only program that is able to detect, track, and control coronary plaque better than any other process I know of is this program.

Note: I am not proposing that a heart disease prevention program like Track Your Plaque can replace a procedure like coronary bypass when a dangerous situation has developed. The Track Your Plaque program is designed to be implemented in the years before heart surgery is required. That's when you have the greatest control over your fate.

Surprise: Heart scan score reversal

Gene is a jovial, fun-loving railroad worker who didn't take anything too seriously--including his heart scan score of 767.

This score placed Gene solidly in the 99th percentile (in the worst 1%). It came as no surprise to Gene. After all, his father died at age 36 of a heart attack and Gene's brother died at 60 of a heart attack. So Gene took life as it came and long ago decided not to fret about his fate.

But Gene's wife prodded him and prodded him to get the heart scan. That's when I met him.

Of course, Gene had been prescribed Lipitor by his doctor for a somewhat high LDL cholesterol. Our assessment uncovered several additional patterns including lipoprotein (a), small LDL, a pre-diabetic tendency, and a severe deficiency of vitamin D.

At 224 lb and 5 ft 6 inches in height, I felt that Gene was at least 40 lbs overweight.

One year later and with reasonable correction of all his patterns except weight loss and Gene's heart scan score was 590--a reduction of 23%!

Gene was thrilled, as was I. But, frankly, I was also surprised. Dramatic regression of coronary plaque tends to not occur so readily as long as pre-diabetic patterns persist and weight is not controlled.

The lesson: Often the only way to tell if you've achieved control or regression of coronary plaque is to have another heart scan. The tremendous variation in human responses never ceases to amaze me.

Call me when you're having chest pain


I met a patient, Anna, yesterday. She was quite frustrated and frightened.

At age 50, Anna suffered a heart attack and received a stent to her left anterior descending coronary artery. What she found upsetting is that, because several members of her family had suffered heart attacks in their 40s (Dad--heart attack at age 45, paternal uncle--heart attack age 40, and even another uncle with heart attack in his late 20s), she had repeatedly asked her doctor whether she was okay.

She received the usual array of false assurances: "You're feeling fine, right? Then don't worry about it." "Look. Your cholesterol is in the normal range. Even your cholesterol/HDL ratio is fine." "Women don't get heart disease until later in life."

All proved absolutely false. As we talked, Anna exclaimed, "I think what I've been told all along is that we'll take you seriously when you finally have a heart attack!"

She's exactly right. The vast majority of times, heart disease is discovered by accident, usually because of an "event" like heart attack. This is like changing the oil in your car when it finally breaks down--it's too late.

CT heart scan, followed by lipoprotein testing and associated values, then correction of your specific causes. It's that simple.

Optimal medical therapy

I was re-reading some of the details behind the recently announced COURAGE Trial comparing angioplasty/stent in 1100 people compared to "optimal" medical therapy in another 1100. You'll recall that no difference was found.

In particular, over approximately 5 years, 20% of participants in each group died, experienced heart attacks, or strokes. Of those treated with "timal" medical therapy, 32% ended up getting a procedure like stents or bypass anyway due to deteriorating symptoms.

What is "optimal" medical therapy? I bring this up again because the study investigators in COURAGE, as well as in similar trials, say this with a straight face. Optimal medical therapy means aspirin and/or Plavix (the anti-platelet, aspirin-like blood thinner); "aggressive" statin drug therapy to reduce LDL cholesterol to 60-85 mg/dl; and "anti-ischemic" therapy (that reduces angina and the phenomena of poor coronary blood flow) using nitroglycerin preparations, beta blockers, and other drugs.

I do give credit to the investigators for having the courage to perform this trial in a world hell bent on doing procedures and still reporting the neutral outcome. But the notion of "optimal" medical therapy begs for comment.

Indeed, this is regarded as optimal by most practitioners. Some would even argue excessive, based on the low LDL target achieved. Would you be satisfied with a 20% likelihood of heart attack, stroke, or death or 5 years, a 1 in 5 roll of the dice? I would not. Recall that we aim for near-total elimination of risk.

What could have been further "optimized"? Plenty. For instance:

--What is the real LDL, not the fabricated, calculated LDL? The two can be commonly 100 mg/dl different.

--How about raising HDL to 60 mgd/?

--What about reducing the proportion of small LDL particles? After all, small LDL is the number one cause of heart disease in the U.S., not high LDL.

--What is Lp(a)? If you treat LDL with a statin drug, Lp(a) is unaffected and continues to trigger huge plaque growth. You will fail if this is not identified and corrected.

--What is vitamin D3? One of the most powerful facilitators of plaque reversal I know of.

--What are triglycerides? Triglycerides create hidden particles in the blood like intermediate-density lipoprotein, potent triggers for coronary plaque growth. Speaking of intermediate-density lipoprotein, that's another very important pattern to identify, the after-eating persistence of dietary fats.

--Why aren't they taking fish oil? With a 28% reduction in heart attack and 45% reduction in sudden death from heart attack, this alone would have halved the number of "events" in the "optimal" medical treatment group.

Of course, there's more. But the idea that aspirin, statins, and anti-ischemic therapy is somehow optimal is silly and sad at the same time. But that's the bias. The COURAGE Trial does represent a step forward, a step away from the "stent everyone and everything" mentality that motivates my colleagues, aided and abetted by their co-conspirators, the hospitals. But you and I know better. "Optimal" medical therapy, in truth, can mean a far better approach that can dramatically reduce, perhaps eliminate, risks for events like heart attack. The conventional "optimal" medical therapy will suffice only if you're content with a 20% likelihood of heart attack, death or stroke, or a 32% likelihood of an urgent procedure in your future.

Niacin, postprandial patterns

For a detailed report on the very important postprandial (after eating) patterns that contribute hugely to heart disease risk, read my recent article in Life Extension Magazine, available (no cost) at:

For a report on using niacin to reduce risk of heart disease, see another report in the same issue of Life Extension:

Also, keep your eyes open for a lengthy report focused exclusively on the Track Your Plaque program in an upcoming issue of Life Extension. I'll provide links in this Blog when it comes out.

What's better than fish oil?

One of the recent questions on our Track Your Plaque Forum related to what to do about a triglyceride level of 101 mg/dl while on fish oil.

Recall that, contary to conventional thinking like that articulated in the ATP-III cholesterol treatment guidelines, we aim to reduce triglycerides to 60 mg/dl or less. This is important to suppress the formation of abnormal triglyceride-containing lipoprotein particles, especially small LDL, reduced HDL, lack of healthy large HDL, VLDL. ATP-III advises a level of 150 mg/dl or less. Unfortunately, triglyceride levels this high guarantee appearance of all these undesirable particles and an increasing heart scan score.

What's better than 4000 mg of fish oil for its 1200 mg of EPA and DHA (omega-3 fatty acids)? More fish oil. In other words, the 4000 mg fish oil providing 1200 mg EPA + DHA is our minimum. A simple increase to 6000 mg to provide 1800 mg EPA + DHA is usually all that is necessary to reduce triglycerides and put a halt to the cascade of abnormal lipoprotein particles that trigger plaque growth. Occasionally, a somewhat higher dose may be required. Doses are best divided into two, with meals (e.g., three capsules twice a day).

Another important issue: An over-reliance on wheat products can also increase triglycerides. This includes any flour product like breads (regardless of whether it's white, whole wheat, or whole grain--they all raise triglycerides), pretzels, bagels, breakfast cereals, and pasta. A dramatic reduction in wheat-containing products will reduce triglycerides substantially, help you reduce your abdominal fat, reduce blood pressure, raise HDL and reduce small LDL, clear your mind, provide more energy, avoid afternoon "fogginess" . . . Huge benefits.

Valve disease and vitamin D

There are two common forms of heart valve disease: aortic valve stenosis (stiffness) and insufficiency (leakiness), and mitral anular calcification.

Both valve issues are regarded as evidence of senescence, or aging--the older you are, the more likely you will have one or both. Both conditions involve progressive calcium deposition and, to some degree, cholesterol deposition. They might be regarded as phenomena of "wear and tear" just like hip arthritis.

There are no known therapies to stall or stop the development of mitral anular calcification. However, several attempts have been made over the years to identify treatments that can slow or stop the progression of aortic valve disease, which is becoming increasingly common and is addressed by surgical valve replacement when severe. The most recent trials have examined whether high-dose Lipitor (80 mg) has any effect (it did not) and high dose Crestor (40 mg), which slowed but did not stop the deterioration of stiff valves.

It's been my suspicion that vitamins D and K2 may play a crucial factor in valve health. After all, vitamin D is the master controller of calcium deposition. Preliminary data also suggest that people who are intentionally made vitamin K deficient with the drug, Coumadin, develop twice the calcium deposition on aortic valves that non-Coumadin takers develop.

I saw a patient Friday, Marianne. In addition to a moderate heart scan score of 379 at age 71, Marianne had a leaky (insufficient) aortic valve. By an echocardiogram 18 months ago, the valve was moderately leaky. I put Marianne on vitamin D, 4000 units, to raise her blood level to 50 ng/ml.

Last week, I asked Marianne to have another echocardiogram. This time, no leakiness whatsoever--none. I have never seen this happen before. Although Marianne is only one example and we don't want to extrapolate too far from the experience of one person, it's hard not to attribute this phenomenal response to vitamin D supplementation.

I wonder what would have happened if we had added vitamin K2, as well?

Anyway, just another potential wonderful effect of vitamin D restoration.

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 wil

Niacin vs. low-carb weight loss

Niacin:

--Raises HDL and shifts HDL towards the healthier large (HDL2b) subclass.
--Reduces total LDL.
--Reduces small LDL particles.
--Reduces triglycerides and triglyceride-containing particles like VLDL and IDL (intermediate-density lipoprotein).
--Reduces fibrinogen.
--Reduces inflammatory responses.


Weight loss achieved through a low-carbohydrate (read "wheat-free") diet:

--Raises HDL and shifts HDL towards the healthier large (HDL2b) subclass.
--Reduces total LDL.
--Reduces small LDL particles.
--Reduces triglycerides and triglyceride-containing particles like VLDL and IDL (intermediate-density lipoprotein).
--Reduces fibrinogen.
--Reduces inflammatory responses.


Curious, isn't it? Niacin achieves virtually the same effect as weight loss achieved through a low-carbohydrate diet, particularly if free of wheat products. The only major difference is that niacin also reduces lipoprotein(a), though even that distinction shrinks if monounsaturated fat sources like almonds are included in a low-carbohydrate program.

So which should you do first if you have any of the above patterns? Well, it's a question of 1) severity, 2) how carbohydrate-rich your starting diet is, 3) how much weight you could stand to lose, and 4) how urgent your program is (determined largely by your heart scan score).

Niacin can also be very helpful if you've taken full advantage of weight loss through a carbohydrate-restricted program, yet still retain some of the abnormal lipoprotein patterns that could continue to grow coronary plaque. For instance, if HDL cholesterol rises from 28 to 40 mg/dl by eliminating wheat and reducing carbohydrates and losing weight, niacin could raise HDL to 50 mg/dl or higher.

As much as I love and use niacin for its broad array of plaque-controlling effects, a low-carbohydrate, wheat-free diet can achieve many of the same effects. Use this strategy to full advantage.

Explosive plaque growth

Every once in a while, we will see someone experience more-than-expected rate of coronary plaque growth, a sudden jump in heart scan scores. I'm talking about increases in score of 50%, even 100%, sometimes despite favorable lipid and lipoprotein patterns.

It's not always easy to pin this phenomenon down, since we often detect it after a year or more on a repeat heart scan. It would be wonderfully insightful to perform heart scans more frequently and track plaque growth more precisely, but of course, radiation exposure is the most important limiting factor, as is cost.

So this list is, admittedly, speculative. It is based on observation, on presumptive associations between events and heart scan scores. But, judging from what we do confidently know about coronary atherosclerotic plaque, I think these observations make physiologic sense.

These are the sorts of increases in heart scan score that can scare the heck out of you, silent yet explosive growth of coronary atherosclerotic plaque that can grow with no warning whatsoever.

Factors which I have observed to possibly be responsible for explosive plaque growth include:

--Overwhelming tragedy such as death of a loved one, financial ruin, divorce. One of my early and catastrophic failures was a young man in his early 40s who, in the space of just a few months, suffered the loss of his mother, a brother, and his mother-in-law, while working a high-stress job. His heart scan score doubled from around 100 to 200 in one year, despite perfect lipoproteins. He had a heart attack shortly after the second score, despite a normal stress test just months earlier. (Pessimism is tragedy's weak cousin, but one that still holds power to corrupt our otherwise best efforts at plaque reversal.)

--Substantial weight gain. In the early years of the Track Your Plaque program, before it was even called "Track Your Plaque," I witnessed a man more than double his score from 1100 to 2400 in 18 months just by allowing himself to gain 40 lbs. (I don't know what became of him. His life apparently suffered other disasters, as well, and we lost track of him.)

--Poorly-controlled diabetes. High blood sugars out of control have yielded explosive growth.

--Kidney disease--However, I am uncertain of how much this overlaps with a deficiency of vitamin D's active form, 1,25-OH-vitamin D3, the form that is often deficient in people with dysfunctional kidneys.

--An inflammatory disease that is out of control, e.g., rheumatoid arthritis.

--This is very speculative, but I've witnessed explosive growth after vaccine administration that yielded strange viral-like symptoms. In this one instance, the man was getting heart scans (on his own) every three to six months and described a severe illness following a vaccine administered in preparation for travel out of the U.S.

--Unrecognized low thyroid function--i.e., hypothyroidism. This is easily corrected with thyroid hormone replacement.


These factors can also be relative and they can be overcome. Look at our current Track Your Plaque reversal record-holder: a 53-year old woman who dropped her heart scan score an amazing 63% despite the loss of a loved one during the 15 months of her program. Despite an overwhelming tragedy, she overcame the potential adverse effects and set a record, probably a record for the entire world.

Dr. Cannell on "How much vitamin D?"

In his most recent Vitamin D Council Newsletter (reprinted in its entirety below, minus clickable links, as Dr. Cannell apparently lost his webmaster and this issue of the newsletter is therefore not posted on the Vitamin D Council website; if you would like to either donate money to the Vitamin D Council or pitch in with help with his website, go to www.vitamindcouncil.com), Dr. John Cannell once again enlightens us with some new insights into vitamin D and its enormous role in health. In this issue, he discusses the role of vitamin D in people diagnosed with cancer (treatment, not prevention).

While cancer is not our focus on the Heart Scan Blog, Dr. Cannell's always insightful comments provide some helpful thoughts for our management of vitamin D doses and blood levels.

Dr. Cannell cites a recent study from vitamin D research expert, Dr. Bruce Hollis:

In the first study of its kind, Professor Bruce Hollis of the Medical University of South Carolina gave all of us something to think about. He asked and answered a simple question: How much vitamin D do you have to take to normalize the metabolism of vitamin D?

Remember, unlike other steroid hormones, vitamin D has very unusual metabolism in most modern humans, called first-order, mass action, kinetics. All this means is that the more vitamin D you take, the higher the 25(OH)D level in your blood, and the higher the 25(OH)D level in your blood, the higher the levels of activated vitamin D in your tissues. No other steroid hormone in the body behaves like this. Think about it: would you like your estrogen level to be dependent on how much cholesterol you ate? Or your cortisol level? (I'd ask the same about testosterone levels but I know men well enough not to ask.) No, the body must tightly regulate powerful steroid hormones through substrate inhibition, that is, if an enzyme turns A into B, when the body has enough B, B inhibits the enzyme and so limits its own production.

Not so with vitamin D, at least at modern human vitamin D levels. Professor Reinhold Vieth was the first to write about this and Vieth's Chapter 61 in Feldman, Pike, and Glorieux's wonderful textbook, Vitamin D (Elsevier, 2005, second edition), is a great reason to buy the textbook or have your library do so. (I'm glad to see Amazon is out of stock of the new ones (someone must be reading about vitamin D) but you can still buy used editions.)

Why would the kinetics of vitamin D be different from all other steroids? Maybe they are not, Hollis reasoned, like Vieth before him. Maybe vitamin D levels are so low in modern humans that its metabolic system is on full blast all the time in an attempt to give the body all the vitamin D metabolites it craves. So Hollis asked, Is vitamin D's metabolism different in populations in the upper end of 25(OH)D levels (a population of sun-exposed people and a group of women prescribed 7,000 IU per day)? Note, the Hollis study is free on Medline, you can download the entire paper on the right hand of the PubMed page below.

Hollis BW, et al. Circulating vitamin D3 and 25-hydroxyvitamin D in humans: An important tool to define adequate nutritional vitamin D status. J Steroid Biochem Mol Biol. 2007 Mar;103(3-5):631-634.

If you look at the two graphs, Figures 1 and 2 of Hollis' paper, you find vitamin D's kinetics can be normalized, made just like all other steroid hormones in the body, but you have to get enough sunshine or take enough vitamin D to get your 25(OH)D level above 50 ng/ml, and 60 ng/ml would be better. Then your body starts to store cholecalciferol in the body without much further increase in 25(OH)D levels. The reaction becomes saturable. This is a remarkable discovery and it implies levels of 30 and 40 ng/ml are usually not sufficient. It also implies actual vitamin D levels (cholecalciferol levels), not just 25(OH)D levels, may be useful in diagnosing and treating deficiency. Note, that not all of the sun-exposed individuals or women prescribed 7,000 IU/day achieved such levels. That's because the sun-exposed individuals were tested after an Hawaiian winter and because prescribing and taking are two different things.

In answer to the question, "How much vitamin D should someone with cancer take?," Dr. Cannell advises:
"Take enough to get your 25(OH)D level above 60 ng/ml, summer and winter." In doing so, you will have normalized the kinetics of vitamin D and stored the parent compound, cholecalciferol, in your tissues. In the absence of sunshine, you need to take about 1,000 IU/day per 30 pounds of body weight to do this. A 150 pound cancer patient may need to take 5,000 IU per day, a 210 pound cancer patient about 7,000 IU per day, all this in the absence of sunlight.

Dr. Cannell, no stranger to the resisitance among many practicing physicians unaware of the expanding and robust literature on vitamin D, advises people with cancer that:
In the end, if you have cancer and your physician won't do a risk/benefit analysis, do it yourself. The risk side of that equation is easy. Both Quest Diagnostics and Lab-Corp, the two largest reference labs in the USA, report the upper limit of 25(OH)D normal is 100 ng/ml and toxic is above 150 ng/ml, so 60 ng/ml is well below both. The reason levels up to 100 ng/ml are published normals is because there is no credible evidence in the literature that levels of 100 ng/ml do any harm and because sun worshipers often have such levels. (If you don't believe me, go to the beach in the summer for one month, sunbath every day for 30 minutes on each side in your bathing suit, and go home and have a 25(OH)D level.) By getting your level above 60 ng/ml, all you are doing is getting your levels into the mid to upper range of laboratory reference normals. Little or no risk.

The Vitamin D Newsletter
January, 2008


The January newsletter is coming early as I will be out of touch for awhile. If you remember, the last newsletter was on preventing cancer, not treating it. Below is a sampling of the tragic emails the last newsletter generated:


"Dr. Cannell, I was just diagnosed with breast cancer, how much vitamin D should I take?"

"My mother has colon cancer, how much vitamin D should she take?"

"I've had prostate cancer for four years, is there any reason to think vitamin D would help?"

"Dr. Cannell, my son has leukemia, should I give him vitamin D?"


It's one thing to talk about evidence vitamin D may prevent cancer but something quite different to discuss evidence vitamin D might help treat cancer. I used to think the answers to all the above questions were the same. Like anyone else, people with cancer should be screened for vitamin D deficiency and be treated if deficiency is present. Simple. However, it's not that simple. The real questions are, What are reasonable 25-hydroxy-vitamin D [25(OH)D] levels for someone with a life-threatening cancer? How much vitamin D do they need to take to obtain such levels? Is there any evidence, of any kind, that vitamin D will help treat cancer? The risk/benefit analysis of taking vitamin D is quite different if you are in perfect health than if your life, or your child's life, is on the line.

Remember, unlike cancer prevention, not one human randomized controlled trial exists showing vitamin D has a treatment effect on cancer. By treatment effect, I mean prolongs the lives of cancer patients. However, as I cited in my last newsletter, Dr. Philippe Autier of the International Agency for Research on Cancer, and Dr. Sara Gandini of the European Institute of Oncology, performed a meta-analysis of 14 randomized controlled trials showing even low doses of vitamin D extend life but they looked at all-cause mortality, not just cancer (Arch Intern Med. 2007;167(16):1730-1737). However, some epidemiological studies indirectly address the treatment issue and are quite remarkable. The first are a series of discoveries by Professor Johan Moan, Department of Physics at the University of Oslo, with Dr. Alina Porojnicu as the lead author on most of the papers.

What Professor Moan's group discovered, repeatedly, is quite simple, whether it be cancer of the breast, colon, prostate, lung, or a lymphoma. You live longer if your cancer is diagnosed in the summer. And it is not just Moan's group who has found this. A huge English study recently confirmed Moan's discovery.

Lim HS, et al. Cancer survival is dependent on season of diagnosis and sunlight exposure. Int J Cancer. 2006 Oct 1;119(7):1530-6.

What do these studies mean? Something about summer has a treatment effect on cancer. Whatever it is, you live longer if you are diagnosed in the summer but die sooner if you are diagnosed in the winter. What could it be about summer? Exercise?
