Vitamin D increased my cholesterol

A friend told me this story.

Her friend, Linda, had added vitamin D to her daily supplements. Because she'd had a vitamin D blood level of 22 ng/ml, she was taking 6000 units per day.

However, Linda also had a high cholesterol value with a total cholesterol of 231 mg/dl. After several months on the vitamin D, she had another cholesterol panel. Total cholesterol: 256 mg/dl.

"It must have been the vitamin D! So I stopped it right away."

Is this true? Does vitamin D raise the level of blood cholesterol? Yes, it does. But it's a good thing. Let me explain.

Followers of The Heart Scan Blog know that total cholesterol is really a mix of 3 other factors:

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

This is the Friedewald equation, still used today in over 95% of cholesterol panels. So, by the Friedewald equation, anything that increases LDL, HDL, or triglycerides will increase total cholesterol.

One of the spectacular changes that develops over a year of taking vitamin D is that HDL cholesterol skyrockets. While sensitivity to this effect varies (probably on a genetic basis), HDL increases of 10, 20, even 30 mg/dl are common. A starting HDL, for instance, of 45 mg/dl can jump up to 65 or 70 mg/dl, though the effect requires up to a year, sometimes longer.

Vitamin D can also reduce triglycerides, though the effect is relatively small, usually no more than 20 mg/dl or so. Likewise, the effect on LDL is minor, with a modest reduction in the small type of LDL.

So the dominant effect of vitamin D from a cholesterol standpoint is a substantial increase in HDL. Looking at the equation, you can see that an increase in HDL is accompanied by a commensurate increase in total cholesterol. If HDL goes up 25 mg/dl, total cholesterol goes up 25 mg/dl.

So Linda is absolutely correct: Vitamin D increases cholesterol--but it's a good thing that reduces risk for heart disease and is an important part of a coronary plaque-reversal program.

This is yet another reason why I advocate elimination of total cholesterol on lipid panels. There is no useful information in the total cholersterol value, only the potential for misinformation.

Nutrtional ignorance is not unique to the U.S.

Heart Scan Blog reader from Australia, Michaela, also a mother of a son with a complex congenital heart defect, wrote this series of e-mails to me. (Published with Michaela's permission.)


I've been reading the article, Valve disease and Vitamin D from April '07, by Dr William Davis. I'm hoping you may have some information on the topic. I'm hoping someone will have time to help me.

I have been supplementing my 15 year old son with Vit D for 4 months but only 1000 (U) per day. I would like to increase the dosage but am not sure if I would do him more harm than good.

I have been researching vitamins and supplements on the net for a few months and have been amazed at what I have found. I only wish I had done it years ago. My son has been let down by the Australian Medical Profession and it's a race against time now to keep him well and avoid a heart transplant.

My son was born with aortic stenosis and had a valvotomy at 4 weeks of age. This damaged the aortic valve and he had a Ross Repair procedure at aged 3. This left him with a damaged heart muscle and leaking aortic & pulmonary valves. In May '08, his heart grew more enlarged, causing the mitral & tricuspid valves to also leak.

I took him to Bangkok in Feb this year where he had 70 million of his own Adult Stem Cells directly injected into his heart muscle with the hope of strengthening the muscle and eventually valve replacement.

My son has recovered from the surgery and is once again symptom-free, thanks to the wonderful advice followed by the Author & Cardiologist, Stephen T. Sinatra. I have followed his supplement regime and what a difference! Of course, this won't last while my son's valves continue to leak.

My son has also developed secondary hyperparathyroidism, bone thinning and hypothyrodism. Vit D & Calcium have something to do with this I believe.

My Australian Doctors have never made mention of any vitamins or supplements .... EVER! Transplant is all they will consider and we are not having it.

If you have any info or links to any sites which may be useful to me, could you email them to me? I would be grateful for any help I could get.

Sincerely
Michaela



I responded to Michaela's e-mail:

Hi, Michaela--

Vitamin D is extremely important. Sometimes, hyperparathyroidism and calcium derangements are caused by vitamin D deficiency. You might be able to get help with this from an endocrinologist, since they are the ones who deal with hyperparathyroidism. An endocrinologist might even be familiar with several recent studies that document this phenomenon:

Vitamin D therapy in patients with primary hyperparathyroidism and hypovitaminosis D

Vitamin D deficiency and primary hyperparathyroidism

Also, see the discussions at www.vitamindcouncil.org from Dr. John Cannell.

Because of the complexity of your son's health, it might be hazardous to stray too far away from conventional care though you and I know that there are limitations to that perspective. For that reason, I would urge you to press for answers from a knowledgeable endocrinologist.

I hope you find the answers you need.

William Davis, MD



Several months later, Michaela provided this update:

Hi Dr Davis,

I wrote to you back in July regarding my 15 year old son's need for a Heart Transplant through a failed Ross Repair and the possible Vitamin D connection. You sent me some valuable links and I thank you again for that.

I just wanted to let you know, I think you have given me the answers. I increased Lee's Vitamin D supplement to 6000U a day and, along with the recommended nutritional supplements of US Cardiologist Dr Stephen T Sinatra, there have been remarkable improvements! Lee also had 70 million of his own Adult Stem Cells injected into his heart in February. As we know, Stem Cell Therapy takes time and Lee was looking like time was quickly running out.

I have removed him from the transplant list. He is now reading normal Kidney function, the BNP (Brain Natriuretic Peptide, a measure of heart failure] has dropped by 7000 and his liver size has reduced to where it no longer causes him discomfort. The liver tests show it's still affected but it's function is improving each month. His last Echo was in early July and there had been a reduction in the size of his heart, which is so important.

To the Doc's, Lee can't get better, there is only transplant or death so you can imagine the surprise on their faces to see him looking and feeling so well with their tests to back it up. Still, even though it's staring them in the face, they don't want to know about it. They have no interest in what supplements he is on or Stem Cell therapy. God help their other patients. I view them in the waiting room and think of them as lambs to the slaughter.

We are not spoiled for choice with Doc's here in Western Australia. I have to take what I can get and there is not many who would take on Lee's case. He was number 1 on the transplant list and a most urgent case. Not many were willing to even look at him with his cardiac history and all I had to help was the arrogant Doc's at the Advanced Heart Failure Unit. They were not at all interested in his secondary hyperparathyroidism. I suppose it didn't matter what else he had compared to his heart problems.

Anyway, I'm writing to thank you. Lee would be transplanted or dead now if it wasn't for Dr's like you sharing their knowledge online. I wish I had researched things years ago, Lee might not have sunk so low if I had. I don't know if the transplant can be held off indefinitely, but like I tell Lee, "Stay well. There are amazing people out there doing amazing things, if you can just hang on. The miracle is around the corner." He's so well, you'd have to see him to believe it. But I have 7 kids and Lee is as physically active and as well as the other 6! For how long he can stay like this, I don't know but if his ejection fraction [a measure of left ventricular strength] can keep climbing and his body gets stronger, I have hope for another attempt at valve replacement.

I'm still shocked and angry that nutritional supplements have never been mentioned in the 15 years I've been dealing with cardiologists. Surely they know about them. I have read through dozens of reports online of the benefits of them--Why haven't they?! Thank God for the online Doc's such as yourself, the valuable info would never make it out of a Doctor's office in Western Australia! I've had to leave my country for Stem Cell therapy and then implore overseas Doc's for advice and information. What does that say for the Australian Medical Profession? Not a lot! They put him in the position he is in yet don't want to help get him out.

I'm so very grateful to you, thank you and God bless.

Michaela

Eat cranberries

Most people already know that cranberries are useful for preventing urinary tract infections. Cranberries can also be useful for preventing other sorts of infections, such as dental cavities and stomach ulcers because of cranberry's ability to block bacterial adhesion.

Cranberries can also be a useful component of a heart healthy program.

Several unique properties of cranberries contribute to various aspects of heart health:

• Cranberries are a rich source of pectin--Pectin is a soluble fiber, the sort that binds bile acids in the intestinal tract and naturally reduces LDL cholesterol.
• Cranberries are a rich source of polyphenols and flavonoids--Including the wonderfully fascinating anthocyanins, the flavonoids that confer the beautiful red color. Surprisingly, cranberries are richer in polyphenols and flavonoids than blueberries, strawberries, and grapes. Cranberry juice is also rich in these compounds. However, beware of cranberry juice "cocktail," which is diluted with other liquids such as high-fructose corn syrup. Like grapes, cranberries are a source of resveratrol, the polyphenol also found in red wines that some believe is responsible for reduced risk for heart disease and extending life.
• Cranberries have high antioxidant activity--Cranberries are among the highest in antioxidant capacity against superoxide radicals, hydrogen peroxide, and hydroxyl radicals, oxidizing factors believed to underlie heart disease, cancer, and aging. Cranberries also reduce the oxidation of LDL cholesterol particles.
• Cranberries block uric acid production--Cranberries have the unique ability to block the activity of an enzyme, xanthine oxidase, that converts xanthine to uric acid. Uric acid is believed to add to heart disease risk and is the factor responsible for gout.
• Cranberries increase HDL cholesterol--Cranberry juice increases HDL by 3-4 mg/dl.

Cranberries are only modest sources of sugars, with 7.19 grams “net” carbohydrates (total carbohydrates minus fiber content) per cup of whole raw cranberries.

The best way to eat cranberries is to consume the real thing: eat the whole berry, as in sugar-free cranberry sauce or added to baked dishes like chicken. Second best are dried cranberries. However, be careful of the overly-sweetened dried cranberries that contain added sugar (for a total of 78 grams sugar per cup--far too much). Unsweetened dried cranberries can be purchased, or you can dry them yourself.

Cranberry juice is another way to obtain the health benefits of cranberries; the unsweetened juice, while quite tart, is the best with 30.5 grams sugar per 8 oz--so don't drink more than 4 oz at a time. The more common cranberry juice “cocktails” are generally too sugary and/or too dilute for full health benefit.

The cranberry harvest season in Wisconsin, Michigan, Oregon, Massachusetts, and New Jersey is just getting underway, so we should be seeing fresh cranberries on store shelves or farmers' markets any day now.

Procedures 'R Us

Kay came to the office for an opinion.

Over the past 8 months, she'd received a stent to the left anterior descending coronary artery and, during a separate procedure, a stent to the left subclavian artery.

"My cardiologist was very capable doing procedures. But when I asked, 'What do I do now?' he barely said a word and handed me a presciption for Crestor."

This kind of incredible neglect is the norm: Write a prescription for statin drug, delegate dietary advice to the hospital dietitian who advocates a heart disease-causing low-fat diet, followed by hospital discharge. You are expected to report any recurrent symptoms (which are inevitable), at which point you might "qualify" for another procedure.

It would be malpractice if it were not the prevailing standard in the community. Yes, the prevailing standard is neglect--neglect to identify, quantify, and correct all the identifiable causes of heart disease; neglect to discuss the nutritional methods that actually correct the abnormal patterns that cause heart disease; neglect to discuss nutritional supplements or medications beyond statins that further reduce heart disease risk and "need" for more procedures. In other words, the prevailing community standard is to stent, bypass, prescribe statin. It is not to understand why the disease occurred in the first place, correct the causes and minimize or eliminate any future danger or need for procedures.

I see consultation after consultation involving stories just like Kay's. People are frightened and they sense intuitively that nobody raised the question of why they have a potentially fatal disease.

Don't allow yourself to fall victim to this incredibly neglectful mode of practice, the one that has enriched hospitals, the drug industry, many cardiologists, but does little to address the actual disease.

Unexpected effects of a wheat-free diet

Wheat elimination continues to yield explosive and unexpected health benefits.

I initially asked patients in the office to eliminate wheat because I wanted to help them reduce blood sugar and pre-diabetic tendencies.

A patient would come to the office, for example, with a blood sugar of 118 mg/dl (in the pre-diabetic range) and the other phenomena of pre-diabetes or metabolic syndrome (high blood pressure, high inflammation/c-reactive protein, low HDL, high triglycerides, small LDL), and the characteristic wheat belly. Eliminate wheat and, within three months, they lose 30 lbs, blood sugar drops to normal, blood pressure drops, triglycerides drop by several hundred milligrams, HDL goes up, small LDL plummets, c-reactive protein drops.

People also felt better, with flat tummies and more energy. But they also developed benefits I did not anticipate:

--Improved rheumatoid arthritis--I have seen this time and time again. Eliminate wheat and the painful thumbs, fingers, and other joints clear up dramatically. Many former rheumatoid sufferers people tell me that one cracker or pretzel will trigger a painful throbbing reminder that lasts a couple of hours.

--Improved ulcerative colitis--People incapacitated with pain, cramping, and diarrhea of ulcerative colitis (who are negative for the antibodies for celiac disease) can experience marked improvement. I've seen people be able to stop all their nasty colitis medications just by eliminating wheat.

--Reduction or elimination of irritable bowel syndrome

--Reduction or elimination of gastroesophageal reflux

--Better mood--Eliminating wheat makes you happier and experience more stable moods. Just as wheat is responsible for a subset of schizophrenia and bipolar illness (this is fact), and wheat elimination generates dramatic improvement, when you or I eliminate wheat, we also experience a "smoothing" of mood swings.

--Better libido--I'm not sure whether this is a consequence of losing a belly the size of a watermelon or improvement in sex hormones (esp. testosterone) or endothelial responses, but more interest in sex typically develops.

--Better complexion--I'm not entirely sure why, but various rashes will often dissipate, bags under the eyes are reduced, itching in funny places stops.


It's also peculiar how, after someone eliminates wheat for several months, re-exposure of an errant cracker or sandwich results in cramping and diarrhea in about 30% of people.

Obviously, people with celiac disease, who can even die of exposure to wheat, are even worse. What other common food do you know of that makes us sick so often, even occasionally with fatal outcome?

Is Lp(a) part of your legacy to your children?

If you have lipoprotein(a), Lp(a)--the most aggressive known cause of heart disease that no one has heard of--then you need to tell your children.

Lp(a) is a "cleanly" inherited genetic pattern: If either parent has it, there's a 50% chance that you have it. If you have it, then there's a 50% likelihood that each of your children has it. (Note that each child experiences a likelihood of 50%, not 50% of your children. This is because each child is conceived as an independent statistical event. So much for romance!)

The atherogenicity (plaque-causing potential) of Lp(a) also tends to get transmitted. In other words, if your Dad had a heart attack at age 50 due to Lp(a) and you share Lp(a), then you likely share a similar magnitude of risk as your Dad. If your Mom had Lp(a), though passed quietly at age 89 without any overt evidence of heart disease, then you are likely to share the relatively benign form of Lp(a).

For most of us with Lp(a), however, it is best to assume that it has at least some potential for causing heart disease, being the most aggressive cause known. (That is, until we have the ability in everyday clinical practice to characterize Lp(a) by assessing such factors as the size of the apoprotein(a) molecule, the number of kringle "repeats" on the tail, etc. Until then, we need to rely on the crude, though helpful, observation of family history.)

At what age should you inform your children? There's no hard-and-fast rule. However, I generally suggest to patients that they talk about Lp(a) with their children when they reach their 20s or 30s, old enough to begin to understand the implications and begin to think about adopting healthier lifestyles. Is treatment required at, say, age 35? That depends on the pattern of Lp(a)-related heart disease in the family: With exceptionally aggressive forms, it might be reasonable to begin treatment at this relatively early age.

Do "Heart Healthy" sterols cause heart disease?

The sterol question continues to pop up.

Sterols are an ingredient widely added by food manufacturers that allows a "heart healthy" claim, since sterols have been shown to reduce LDL cholesterol (at least transiently). HOWEVER, sterols have also been implicated in possibly increasing risk for heart disease. After all, people with the genetic condition called sitosterolemia absorb sterols into the blood and develop coronary heart disease in their teens and twenties. Those of us without sitosterolemia who increase sterol intake with sterol-enriched foods increase blood levels of sterols several-fold. Is this healthy, or does it contribute to coronary plaque as it does in people with sitosterolemia?

Below, I've reprinted a previous Heart Scan Blog post on sterols.


Sterols should be outlawed

While sterols occur naturally in small quantities in food (nuts, vegetables, oils), food manufacturers are adding them to processed foods in order to earn a "heart healthy" claim.

The FDA approved a cholesterol-reducing indication for sterols , the American Heart Association recommends 200 mg per day as part of its Therapeutic Lifestyle Change diet, and WebMD gushes about the LDL-reducing benefits of sterols added to foods.


Sterols--the same substance that, when absorbed to high levels into the blood in a genetic disorder called "sitosterolemia"--causes extravagant atherosclerosis in young people.

The case against sterols, studies documenting its coronary disease- and valve disease-promoting effects, is building:

Higher blood levels of sterols increase cardiovascular events:
Plasma sitosterol elevations are associated with an increased incidence of coronary events in men: results of a nested case-control analysis of the Prospective Cardiovascular Münster (PROCAM) study.

Sterols can be recovered from diseased aortic valves:
Accumulation of cholesterol precursors and plant sterols in human stenotic aortic valves.

Sterols are incorporated into carotid atherosclerotic plaque:
Plant sterols in serum and in atherosclerotic plaques of patients undergoing carotid endarterectomy.




Though the data are mixed:

Moderately elevated plant sterol levels are associated with reduced cardiovascular risk--the LASA study.

No association between plasma levels of plant sterols and atherosclerosis in mice and men.




The food industry has vigorously pursued the sterol-as-heart-healthy strategy, based on studies conclusively demonstrating LDL-reducing effects. But do sterols that gain entry into the blood increase atherosclerosis regardless of LDL reduction? That's the huge unanswered question.

Despite the uncertainties, the list of sterol-supplemented foods is expanding rapidly:




Each Nature Valley Healthy Heart Bar contains 400 mg sterols.












HeartWise orange juice contains 1000 mg sterols per 8 oz serving.













Promise SuperShots contains 400 mg sterols per container.














Corozonas has an entire line of chips that contain added sterols, 400 mg per 1 oz serving.














MonaVie Acai juice, "Pulse," contains 400 mg sterols per 2 oz serving.














Kardea olive oil has 500 mg sterols per 14 gram serving.










WebMD has a table that they say can help you choose "foods" that are sterol-rich.

In my view, sterols should not have been approved without more extensive safety data. Just as Vioxx's potential for increasing heart attack did not become apparent until after FDA approval and widespread use, I fear the same may be ahead for sterols: dissemination throughout the processed food supply, people using large, unnatural quantities from multiple products, eventually . . . increased heart attacks, strokes, aortic valve disease.

Until there is clarification on this issue, I would urge everyone to avoid sterol-added "heart healthy" products.


Some more info on sterols in a previous Heart Scan Blog post: Are sterols the new trans fat? .

Why obese people can't fast

Why do obese people claim it is impossible to fast?

Most overweight people are terrified at the prospect of facing any period of time without ready access to food. Persuading them to begin a program of intermittent fasting is a hopeless cause. They just refuse.

Contrary to popular opinion, this is not just glutonny at work. It is the effect of what I call "the cycle of hunger," the 2-hour up and down cycle of rising sugar and insulin, followed by their inevitable fall. The precipitous fall of sugar and insulin triggers mental fogginess, fatigue, and insatiable hunger. (By the way, this is the same phenomenon underlying the silly notion of "grazing.")

According to an LA Times article, fasting may be difficult to impossible for some people:

"Ruth Frechman, a registered dietitian in Burbank and spokeswoman for the American Dietetic Assn., says she frequently sees such extreme strategies backfire. 'You're hungry, fatigued, irritable. Fasting is not very comfortable. People try to cut back one day and the next day they're starving and they overeat.'"
(Not surprising, coming from the American Diatetic Assn. They, along with such agencies as the American Diabetes Association, are vocal proponents of low-fat, high-carbohydrate, "healthy whole grain" diets--you know, the diets that make us fat and diabetic.)

Ms. Frechman is correct: Having someone engage in a period of fasting, no matter how brief, when the diet leading up to the fast is filled with "healthy whole grains" and other carbohydrates will result in painful hunger that eventually overcomes any effort. A period of overeating typically follows the aborted attempt.

Fasting cannot work as long as the 2-hour cycle of hunger continues. The first step: Eliminate the 2-hour cycle of hunger by dramatically reducing or eliminating carbohydrates. Our preferred method is to eliminate wheat, cornstarch, and sugars. (Just be aware of wheat withdrawal, the fatigue that develops in the first 5 days after wheat elimination that affects up to 30% of people.)

Once wheat, cornstarch, and sugars are eliminated, hunger reverts to that of physiologic need--appetite will be smaller and less intense, since it is driven by your body's needs, not by abnormal stimulation from wheat, cornstarch, and sugar. The fear of not having food dissolves, the 2-hour cycle of mental fogginess, fatigue, and hunger will be gone.

Intermittent fasting is a wonderful strategy for reducing weight; gaining control over lipids, lipoproteins, and coronary plaque; regaining appreciation for food; reducing appetite. But it's not even worth trying unless you've already eliminated the unnatural appetite triggers that will booby-trap any fasting effort.

Test your own thyroid

134 people responded to the latest Heart Scan Blog poll:


When I ask my doctor to test my thyroid, he/she:

Accommodates me without question 45 (33%)

Questions why, but orders the tests 49 (36%)

Refuses because you seem "healthy" 20 (14%)

Refuses without explanation 4 (2%)

Ridicules your request 16 (11%)



That's better than I anticipated: 69% of physicians complied with this small request. After all, you're not asking for major surgery. You're just asking for a very basic test, as basic as a blood count or electrolytes. 36% of respondents said that their doctor asked why, but still complied; this is simply practicing good medicine--If there is a problem, your doctor would like to know about it.

However, the remainder--31%--were refused in one way or another. Incredibly, 11% were ridiculed.

Although this was not asked in the poll, I believe that it is a safe assumption that you asked with good reason: you're abnormally fatigued, you have been gaining weight for no apparent reason or can't lose weight despite substantial effort, or you feel cold at inappropriate times.

Let's say you're tired. Ever since last summer, you've suffered a gradual decline in energy.

So you ask your doctor to assess your thyroid. He refuses. "You're just fine! There's nothing wrong with you."

You disagree. In fact, you are quite convinced that there is something physically wrong. What do you do?

You could:

--Drink more coffee
--Exercise more in the hopes that it will snap you out of your lethargy
--Sleep more
--Take stimulants of various sorts

Or, you could get your thyroid assessed and settle the issue. But how can you get this done when your doctor won't accommodate you, even though you have perfectly fine health insurance and are simply interested in feeling better and preserving your health?

You could test your thyroid yourself. This is why we're making self-testing kits available. Test kits are available here.

This is yet another facet of the powerful revolution that is emerging: Self-directed health.

Trains, planes, and heart scans

A Heart Scan Blog reader posted the following question:

It is not clear to me why getting a cardiac scan is the necessary first step, if in fact the next step would be to bring down small LDL particles which is revealed on a NMR lipoprofile or VAP test. Why isn't the NMR or VAP test the first thing?

Good question. Think of it this way:

Lipoproteins, as measured via VAP (Vertical Auto Profile) or NMR (Nuclear Magnetic Resonance), provide a snapshot of risk from a metabolic viewpoint at that moment. Lipoproteins shift with the tides of age, menopause, weight changes, even what you ate last evening for dinner (especially small LDL). There are also other factors that cause coronary plaque, as well, not revealed through lipoprotein testing, such as vitamin D deficiency, smoking, high blood pressure, phosopholipase A2, lipoprotein(a), inflammatory factors, thyroid dysfunction, omega-3 fatty acid deficiency, etc.

A heart scan, providing a coronary calcium score, provides an indirect measure of coronary plaque that is the sum total of lipoprotein and other plaque-causing factors that have accumulated up to the time of your scan--regardless of the cause.

It means that two females, each 60 years old, with 70% small LDL, HDL 42 mg/dl, triglycerides 150 mg/dl, and mild hypertension, have identical markers for potential coronary risk, but can have widely different heart scan scores. One might have a score of zero, while the other might have a score of 300.

Why would the same panel of causes measured at one moment yield wildly different quantities of plaque? Several reasons:

1) The lifestyles, eating habits, and weight of each woman differed during their earlier years, not currently reflected in this moment's lipid or lipoprotein patterns. Perhpaps one experienced several years of extraordinary stress from a failed marriage, or suffered through two years of depression that caused her to smoke and overeat.

2) There are hidden factors that affect coronary plaque growth that we are presently not able to detect, e.g., vitamin D receptor genotype, cholesteryl-ester transfer protein variants, variation in inflammatory factors. If we can't measure it, we won't know whether it might influence coronary plaque risk.


With all the changes that occur over a person's life, with the uncertainties of yet-to-be-identified causes for coronary plaque, how can you possible know what your risk for heart disease truly is? Yup--a heart scan. Do it and you will know.

Large new clinical study launched to study. . .niacin


Oxford University has issued a press release announcing plans for a new clinical trial to raise HDL cholesterol and reduce heart attack risk. 20,000 participants will be enrolled in this substantial effort. The agent? Niacin.

How is that new? Well, this time niacin comes with a new spin.

Dr. Jane Armitage, formerly with the Heart Protection Study that showed that simvastatin (Zocor) reduced heart attack risk regardless of starting LDL, is lead investigator. She hopes to prove that niacin raises HDL cholesterol and thereby reduces heart attack risk. But, this time, niacin will be combined with an inhibitor of prostaglandins that blocks the notorious "flushing" effect of niacin.

The majority of Track Your Plaque participants hoping to control or reverse coronary plaque take niacin. Recall that niacin (vitamin B3)is an extremely effect agent that raises HDL, dramatically reduces small LDL, shifts HDL particles into the effective large fraction, reduces triglycerides and triglyceride-containing particles like IDL and VLDL. Several studies have shown that niacin dramatically reduces heart attack. The HATS Study showed that niacin combined with Zocor yielded an 85-90% reduction in heart attack risk and achieved regression of coronary plaque in many participants.

In our experience, approximately 1 in 20 people will really struggle using niacin. Flushes for these occasional people will be difficult or even intolerable. Should Dr. Armitage's study demonstrate that this new combination agent does provide advantages in minimizing the hot flush effect, that will be a boon for the occasional Track Your Plaque participant who finds conventional niacin intolerable.

But you already have access to niacin, an agent with an impressive track record even without this new study. And you have a reasonably effective prostaglandin inhibitor, as well: aspirin. Good old aspirin is very useful, particularly in the first few months of your niacin initiation to blunt the flush.

Although this study is likely to further popularize niacin and allow its broader use, it's also a method for the drug companies to profit from an agent they know works but is cheap and available.

You don't have to wait. You already have niacin and aspirin available to you.

The dark side of CT heart scans

"I just got a heart scan!" declared Eric to his doctor. He handed the report to him.

"Oh my. Your score is 154." The doctor paused, then looked at Eric with a serious look on his face. "If we're going to understand whether or not you're in danger, you'll need a heart catheterization."


I've seen this happen countless times. How can I say this diplomatically? THIS IS WRONG!! In my view, it's absolutely criminal for this to happen. Physician ignorance, profiteering, whatever--it is wrong.

There's very few reasons why someone who has no symptoms should go directly to the cath lab for a procedure. (A rare exception might be an exceptional quantity of plaque in the left mainstem artery, e.g., >100. This is highly unusual.)

Even a nuclear stress test (e.g., thallium) at this level of scoring is only 10-15% likely to be abnormal. That means 85-90% likelihood of being normal. There's rare reasons to perform a heart catheterization in a person with no symptoms and an entirely normal stress test. The vast majority of people like Eric do not need a heart catheterization to discern risk.

If Eric's doctor had been up-to-date on the published literature on the prognostic value of heart scans, he could have advised Eric what the risks were--without a catheterization. Many doctors simply don't want to be bothered. Or, they opt for the more profitable method--a hospital procedure.

Always discuss your heart scan with your doctor--but be armed with information in case your doctor is uninformed or unscrupulous. Unfortunately, that's not uncommon. The Track Your Plaque program is your advocate, a source for unbiased information.

The dirty little secret about aneurysms

Jake had an abdominal aneurysm identified--by accident.

While getting a CT scan of his abdomen for unexplained abdominal pain, a 4.4 cm aneurysm was discovered. Jake's abdominal pain eventually passed without explanation, but he was left with this aneurysm.

Jake's primary care doctor referred him to a surgeon. "It's too small to require surgery right now. Wait a few years and it'll probably get bigger. When it gets to around 5.5 cm, that'll be the time to operate. Let's schedule an abdominal ultrasound or CT scan every 6 months."

Jake then got himself a heart scan. His high score of 879 then led him to my office. Lipoprotein testing, a stress test, correction of his lipoprotein patterns, changes in lifestyle followed. One year later, Jake's heart scan score was unchanged.

How about his abdominal aneurysm? 4.2 cm--a modest quantity of regression. When Jake's surgeon learned of the change, he just shrugged. "Okay, we'll just watch it from here."

Shockingly, the conversation surrounding aneurysms is just like the one Jake received: Let's just watch it grow until you need surgery.

If you've every seen anyone have abdominal aneurysm surgery, you know it is an awful, painful, barbaric process with high risk for major complications like kidney failure and loss of the legs. Waiting for an aneurysm to grow is a lousy solution. Surgeons point out that, although surgery is imperfect, it's better than the alternative: rupture, which is catastrophic with a 50% chance of dying.

But what about stopping the growth of the aneurysm? Or even reversing, or shrinking, it?

Surgeons say it can't be done. Yet we've done it--many times. And it's not that difficult.

The steps to take are very similar to that in the Track Your Plaque program for coronary plaque regression, with a few different strategies. Suppression of inflammation, for instance, plays a more important role and blood pressure must be abolutely normal, even during exercise.

More to come on this important topic in the future, including an upcoming Special Report on the www.cureality.com membership website.

Heart scan scores dropping like stones!!

I saw two instances of dramatic coronary plaque regression today.

John, a 53-years old mechanical lift operator, dropped his heart scan score from 479 to 323--a 32% regression of coronary plaque volume!

Eric, a 50-year consulting engineer, dropped his heart scan score from 668 to 580--a 13% reduction.

Both men did nothing special beyond the principles advocated in the Track Your Plaque program. Recall that, without preventive efforts, your heart scan score is expected to increase by 30% per year. Both men are well on their way to freedom from risk of coronary "events".

Two less people to feed the revenue-hungry hospital procedure system! We need many more like them.

Pre-diabetes: An explanation for explosive coronary plaque growth

Art's first CT heart scan in March, 2006 yielded a concerning score of 1336. He felt fine--no chest discomfort, no breathlessness, etc.

Art agreed to take the statin cholesterol drug his primary care doctor prescribed. He also agreed to take the fish oil, niacin, and some of the nutritional supplements that we advised. But Art just couldn't bring himself to make the commitment to lose weight.

At the start of his program, Art--at 5 ft. 8 inches--was 40 lbs overweight (212 lb). This was important since his blood sugar wavered in the pre-diabetic range, going as high as 130 mg. (The American Diabetes Assn. defines diabetes as a blood glucose of 126 mg or greater.)

One year later, Art's lipid and lipoprotein values were corrected to perfection. But he still weighed in at a hefty 209 lbs--essentially no change. His blood sugar likewise hovered in the 120's.

I felt Art need to be prodded, so I asked him to undergo another heart scan. His score: 1935--a 600 point increase, or 45%!

Only now has Art begun to comprehend to power of diabetes and pre-diabetes to fan the flames of plaque growth. Recent published data, in fact, show that the majority of recently diagnosed diabetics already have well-established coronary artery disease.

Don't let this happen to you. Do not dismiss diabetic patterns as they will catch up to you. If Art can lose the 30-40 lbs in the abdominal weight that is creating the diabetic pattern, he will likely succeed in stopping plaque growth. Otherwise, it's just a matter of time before his heart attack, stent, or bypass.

Who cares if you're pre-diabetic?

Marta is a smart lady. She's worked in hospital laboratories for the last 23 years and knows many of the ins and outs of lab tests and their implications.

After years of being told that her cholesterol was acceptable, she needed to undergo urgent bypass surgery after experiencing severe breathlessness that proved to be a small warning heart attack at age 57. But this made Marta skeptical of relying on cholesterol to identify heart disease risk.

I met Marta two years after her bypass surgery when she was seeking better answers. And, indeed, she proved to have several concealed sources of heart disease: small LDL particles, Lipoprotein(a), intermediate-density lipoprotein (IDL--a very important abnormality that means she is unable to clear dietary fats from her blood), among others. But she was also mildly diabetic with a blood sugar of 131 mg (normal < or = 100 mg). This had not been previously recognized.

As I'm a cardiologist and our program focuses on reversal and control of coronary plaque, I asked Marta to return to her primary care doctor to continue the conversation about diabetes. She was a bit frightened but followed through.

"Well, you're not urinating excessively. And your long-term measure of blood sugar, hemoglobin A1C, is still normal. I wouldn't worry about it. We'll just watch it."

I guess I should know better. What the poor primary care doctor doesn't know is that pre-diabetes and mild diabetes are potent risks for heart disease. In fact, some of the most explosive rates of plaque growth occur when these patterns are present. It's well established that risk for heart attack in a diabetic is the same as that of someone who's already suffered a prior heart attack--very high risk, in other words.

Marta's primary care doctor's advice would be like inquiring about cancer and the doctor says "Let's just wait until it's metastatic--then we'll start to worry." Of course, this is insane.

Pre-diabetes and mild diabetes should not be ignored or just "watched". Even though the blood sugar itself may not be high enough to endanger you, the hidden patterns underlying your body's unresponsiveness to insulin creates a torrent of hidden coronary risk.

Don't get smug!

It may sound silly, but after someone succeeds in stopping their heart scan score from increasing or reduces their score, I warn them to not get smug. Let me explain.

I'll tell you about Jack. I met Jack a few years ago after he had a heart scan at age 39. His score: 1441! A score this high at his age obviously puts him in the 99th percentile. Also recall that a score >1000 carries a 25% annual risk for heart attack.

This captured Jack's attention. At the start, his lipoproteins were disastrous with numerous abnormal patterns. Jack committed to the program. After one year, his lipoproteins were around 80-90% corrected towards perfection. He'd lost 27 lbs, was exercising six days a week, and felt great.

Jack's repeat score one year later: 1107--over a 300 point drop! A huge success. He was ecstatic.

Unfortunately, work and life in general distracted him. Jack allowed himself to drift back to old habits, indulging in fast food 2 or 3 times a week, slacking on exercise such that it became sporadic, half-hearted efforts, and regained 15 lbs. He even failed to show up for appointments and we lost contact for two years.

One day, Jack simply decided to see where he stood, so he got himself another heart scan. The score: 2473--over a doubling from his reduced score.

The message: Long-term consistency is key, even after you've achieved control over your score. Stick with your program--and don't get smug!

Holidays are dangerous!

If you're on holiday from work today, make sure you're not on holiday from your health, too.

Too often, people come back to the office telling me that the holidays simply got out of hand--cookouts, picnics, family gatherings, etc.--and they simply couldn't avoid overeating, overdrinking, sitting around--and gaining 3-5 lbs in a weekend. (Our record is 10 lbs in a weekend!)

I don't want to harp on this issue and ruin your holiday, but I can't stress how important it is that you don't allow this to happen to you. Weight gained in a brief space of time has exceptionally destructive effects. Ever see the movie "Super Size Me"? It's an entertaining and well-done yet graphic portrayal of the damaging effects of rapid weight gain.

Enjoy your time off. Relax, enjoy your family and friends--but continue to pay attention to choosing the right foods, don't overeat, take time out to do something (or several things) physical. It'll pay off hugely in the long run.

More on carotid plaque...

Although not a perfect test, carotid ultrasound is an exceptionally easy and accessible test. Using high-frequency sound, clear images are available for most people.

I say it's not perfect because the way it's done in 2006 makes it a non-quantitative test. It is a qualitative test. In other words, you may find out that there's a 30% blockage ("stenosis"), at the far end of the common carotid artery on the right side. Unfortunately, this gives you an isolated measure of diameter of the plaque compared to the artery. What it does not tell you is what the volume of the entire plaque is. That's a far more accurate measure (and one that is incorporated into your heart scan score, by the way).

Nonetheless, carotid ultrasound is easy, very safe, and available in most hospitals and many clinics. One difficulty: most insurance companies will not allow you to go through a carotid ultrasound scan as a "screening" procedure, i.e., a test just to see if you have a carotid plaque. They will generally pay if you're having symptoms of a stroke or "mini-stroke" (transient ischemic attack, or "TIA"), have an abnormal sound in your carotid ultrasound detected by your doctor (a carotid "bruit"), or some other unusual indications. Sometimes, a resourceful physician will muster up a diagnosis based on something in your history (e.g., left arm numbness, a common and often benign complaint that can also signal stroke).

Another option are the mobile scanners or some hospital services that offer carotid screening, usually for a very modest price. Drawback: Sporadic availability, difficulty in obtaining serial scans, and imprecise reporting since it's viewed as a screening test. But it's better than nothing.

My hope is that, as screening services using safe imaging techniques like ultrasound propagate and increase in direct availability to the public, you'll be able to circumvent the obstacles imposed by your insurance company and even, sometimes, your doctor. But try your doctor first.

Carotid plaque can be shrunk

Rose, a 64-year old woman, just had a 70% carotid blockage identified by a screening ultrasound. When the result was given to her doctor, he prescribed Lipitor and told Rose that an ultrasound would be required every year. She would need carotid surgery, an "endarterectomy", if the blockage worsened.

"Can't I reduce the amount of blockage I have?" asked Rose.

"No. Once you've got it, it doesn't get any better."


Is this true? Once you've got carotid plaque, you can only expect it to get worse and it can't be reduced?

This is absolutely not true. In fact, compared to coronary plaque, carotid plaque is easier to reduce!

Of course, the Track Your Plaque program is designed to help you control or reduce coronary plaque. But, in our experience, people who have both coronary and carotid plaque will show far greater and faster reduction of carotid plaque. Dramatic reductions are sometimes seen. I've personally seen 50-70% blockages reduced to <30% on many occasions.

The requirements to achieve reduction of carotid plaque are very similar to the approach we use to reduce coronary plaque. One difference is that hypertension may play a more important role with carotid plaque and needs to be reduced confidently to the normal range before carotid plaque is controlled.

I find it shocking that the attitude like the one provided by this physician continue to prevail. Unlike coronary plaque, which has a relatively small body of scientific literature documenting how it can be reduced, carotid plaque actually enjoys a substantial clinical literature. Part of the reason is that the carotids are more easily imaged using ultrasound. (Heart structures can be seen with ultrasound, but not the coronary arteries.)

Numerous agents have been shown to contribute to reduction of carotid plaque: statin drugs, niacin, fish oil, the anti-diabetic "TZD" drugs (Actos, Avandia), several anti-hypertensive drugs, vitamin E, pomegranate juice, and several others.

It outrages me to hear stories like this. Rose is not the only one.

Don't accept the flip dismissals or the over-enthusiastic referral for carotid procedures. Insist on a conversation about plaque regression.


Note: Although I am a vigorous advocate of atherosclerotic plaque regression, this does not mean that if you have a severe (70% blockage or greater), or if there are symptoms from your carotid disease, that you should engage in a program of reversal. You must always take the advice of your doctor if your safety is in question.
