Large new clinical study launched to study. . .niacin

5. June 2006 William Davis (3)

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

4. June 2006 William Davis (0)
"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

2. June 2006 William Davis (1)
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!!

1. June 2006 William Davis (0)
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

1. June 2006 William Davis (0)
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?

31. May 2006 William Davis (0)
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.

For better answers, Track Your Plaque members can read "Shutting Off Metabolic Syndrome" at http://www.cureality.com/library/fl_dp001metabolic.asp on the www.cureality.com website. ("Metabolic syndrome" is the name commonly given to the constellation of abnormalities associated with pre-diabetes and diabetes.)

Don't get smug!

31. May 2006 William Davis (2)
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!

29. May 2006 William Davis (0)
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...

29. May 2006 William Davis (1)
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

28. May 2006 William Davis (1)
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.

How old are you?

17. October 2009 William Davis (21)
George walks into my office. I ask him his age.

"I'm 21 years old," he declares.

Yet I look at George. He's got gray thinning hair, his posture is slumped forward rather than erect, the flesh on his upper arms hangs loosely, he's got wrinkles on his hands and face, brown spots on the back of his hands and arms. He looks more like 70 years old to me. "I don't think you're 21 years old. I think you're 70."

"Prove it," he says.

Okay. What now? Minus any formal identification like a driver's license, how do I prove that George is really 70-something and not 20-something? Not an easy thing, when you think about it. If George were a tree, I'd cut him down and count his rings. Is there such a phenomenon in humans?

This is actually a fascinating area of research, looking for reliable biomarkers of aging.

Among the most quantitative markers of aging is telomere length. Telomeres were once dismissed as nonsense sequences in DNA. However, more recent thought among geneticists is that telomeres shorten with aging and provide the body's cells a timeline of aging. This way, George's cells act like they are 70, not 13, and don't start producing gobs of growth hormone and testosterone in preparation for puberty.

What can slow or stall the shortening of telomere length? There are two I'm aware of:

1) Caloric deprivation--i.e., taking in fewer calories. This was among the theories explored by Dr. Roy Walford during his Biosphere2 experience, based on his work in mice that showed that caloric deprivation nearly doubled lifespan.

2) Vitamin D--Richards et al (2007) found that, the higher the vitamin D, the longer the telomere length. The highest vitamin D levels conferred a 5-year effective difference in telomere length.

So, if I could look inside George's cells and count his telomeres, I could judge with confidence whether he was 21 or 70. Or, he could take vitamin D sufficient to increase blood levels to a healthy range and be more like 65.

No high blood pressure

14. October 2009 William Davis (20)
Primitive cultures that were, until recently, unexposed to the modern world, reveal some important insights into blood pressure.

The Yanomamo of South American, the Xingu Indians of Brazil, rural Kenyans, and the natives of Papua, New Guinea have average blood pressures of 103/63 mmHg. Even more incredibly, while 90% of modern Americans will develop high blood pressure as they age, the members of these primitive cultures do not develop age-related hypertension.

What's the secret? Perhaps the full "secret" of their remarkably low blood pressure has not been fully unraveled, but several observations have emerged:

--They are not exposed to modern processed foods like pretzels, crackers, and breakfast cereals.
--Low-carbohydrate foods. Carbohydrates are largely the product of the food industry, convenience foods bought in stores. No such thing in the jungle.
--Living outdoors, having to forage and hunt, walk to your destination, not drive or wait in line for food.
--Outdoor lives, wearing little more than a few strands of clothing, exposes you to plentiful vitamin D activation from sunlight exposure.
--Consuming wild game, rich in omega-3 fatty acids, enhances endothelial health and reduces blood pressure.
--Wild plants, roots, and berries, as well as wild game, along the coast, are richer in iodine.

The studies examining the habits of the Yanomamo and other primitive cultures focused principally on sodium intake. Indeed, the very low sodium intake of primitive cultures was associated with lower blood pressure--up to 6 mmHg reduction. But there's clearly more to learn than "cut your salt."

Name that food

13. October 2009 William Davis (30)
What common food can:

• Cause destructive intestinal damage that, if unrecognized, can lead to disability and death?
• Increase blood sugar higher and faster than table sugar?
• Trigger an autoimmune inflammatory condition in the thyroid (Hashimoto’s thyroiditis)?
• Create intestinal bloating, cramps, and alternating diarrhea and constipation, often labeled irritable bowel syndrome?
• Trigger schizophrenia in susceptible individuals?
• Cause behavioral outbursts in children with autism?
• Cause various inflammatory diseases such as rheumatoid arthritis, ulcerative colitis, dermatitis herpetiformis, systemic lupus, pancreatic destruction, and increase measures of inflammation like c-reactive protein?
• Cause unexplained anemia, mood swings, fatigue, fibromyalgia, eczema, and osteoporosis?


The food is wheat. Yes, the ubiquitous grain we are urged to eat more and more of by the USDA (8-11 servings per day, according to the USDA food pyramid), American Heart Association, American Dietetic Association, and the American Diabetes Association. Wheat is among the most destructive ingredients in the modern diet, worse than sugar, worse than high-fructose corn syrup, worse than any fat.

What other common food can result in such an extensive list of diseases, even death?

Celiac disease alone, a severe intestinal inflammatory condition from wheat gluten, affects an estimated 3 million Americans (Celiac Disease Foundation). The medical literature is filled with case reports of deaths from this disease, often after many years of struggle with incapacitating intestinal dysfunction and the sufferer's last days plagued by encephalopathy (brain inflammation).

What happens when you remove wheat from the diet?

The majority of people quickly shed 20-30 lbs in the first few weeks, selectively lost from the abdomen (what I call “wheat belly”); blood sugar plummets; triglycerides drop up to several hundred milligrams, HDL increases, LDL drops (yes, wheat elimination is a means of achieving marked reduction in LDL cholesterol, especially the small, heart disease-causing variety); c-reactive protein plummets. In addition to this, intestinal complaints improve or disappear, rashes improve, inflammatory conditions like rheumatoid arthritis improve, diabetes can improve or be cured, and behavioral disorders and mood improve.

Along with the ill-fated low-fat dietary advice of the last 40 years, the advice to eat plenty of "healthy whole grains" is responsible for untold disease and suffering. Yes, if you start with a fast food and junk diet and replace some of the calories with whole grains, you will be better off. (That was the logic--the Nutritional Syllogism--of the studies that established the benefits of whole grains over processed, "white" grains.)

But eliminate wheat grains and health takes a huge leap forward. And, no, there is no such thing as wheat deficiency--B vitamins, insoluble fiber, some protein--can easily be replaced by other foods.

Heart Defects Simplified

12. October 2009 William Davis (0)


For as long as I've known him, echocardiography technologist, Ken Heiden, has had a deep fascination with congenital heart disease. Ken has just written a wonderful book on congenital heart disease called Heart Defects Simplified.

While this is a bit off-topic for the Heart Scan Blog, I know that there is a serious lack of helpful information for people with congenital heart disease and parents of children with congenital heart defects. So I asked Ken to tell us something about his book.



WD: I've reviewed your book and have been thoroughly impressed with the clarity and detail with which you handle a complicated topic. You somehow manage to make it easy to grasp, far more than any other resource I've used in past. Do you feel that your book serves a previously unmet need?

KH: This book serves an unmet need in that it presents the complex subject of congenital heart defects in a simplified manner. Most books on this subject are anywhere from 300-1700 pages in length and tend to be written for doctors. Further, most of these books have very few diagrams, and they rely upon their explanations to describe these defects.

Heart Defects Simplified is 104 pages in length, describes the most common defects, including surgical repairs, in a two-page format with full-color diagrams on the left and complete descriptions on the right of each chapter. The book is particularly written for sonographers, nurses and parents, but it is valuable for anyone interested in this subject. It is particularly useful in clinical situations because it is convenient to lay out at your side with a coil-bound format and durable pages. Further, there are appendixes which include "Surgical Procedures in Alphabetical Order," "Prevalence of Congenital Heart Disease," "Scanning Protocols for Echocardiographers," "Imaging Tips," a glossary and a worksheet for echocardiographers.


WD: I know that many people with loved ones who have congenital heart defects, particularly parents of children with such conditions, are often kept in the dark about the details of the condition. Is your book suitable for the non-technical reader, such as parents?

KH: This book is an excellent resource for parents. It is written in language that is understandable by parents as well as technologists and nurses. The full-color diagrams provide invaluable insight into this very complex world. Most importantly, this book attempts to make the subject of congenital heart defects accessible to anyone who wishes to comprehend this subject.


WD: I understand that people with congenital heart defects and parents are active participants in online discussion groups. Will your book serve as a resource for people who participate in these groups?

KH: This book is not only a resource for sonographers and parents, but the book is accompanied by a blog (HeartDefectsforEveryone.blogspot.com) that attempts to address many of the concerns commonly encountered with congenital heart defects. This blog is a work in progress, but I hope to provide a forum for parents, healthcare personnel, and others to share their questions and concerns about congenital heart disease.

My experience with the omega-3 index

8. October 2009 William Davis (23)
I just got back my own results from the Gene Smart laboratory reporting my omega-3 index and omega-6:omega-3 ratio.

My results:

Omega-3 index: 8.2%

Omega-6:omega-3 index: 3.2 to 1

Not too bad, but not as good as I'd expected. Hmmm.

Although the omega-3 index of 8.2% puts me in the lower risk category for sudden cardiac death, I was hoping for a level of 10% or slightly greater, the level that I believe is more likely to be related to plaque inactivation or reversal. I obtained this level of omega-3 averaging an intake of EPA and DHA of about 2500 mg per day.

I was somewhat disappointed by the omega-6:omega-3 index. Although it's clearly better than the American average range of 20:1, it is short of the ideal of 2:1 or even 1:1. Since I purposely avoid omega-6-rich sources like corn oil, vegetable oils, sunflower or safflower oils, I wonder if I've overdone the nuts. The two ways to improve the omega-6:omega-3 ratio are to 1) decrease omega-6, or 2) increase omega-3. I'm going to do both.

So I thought I was doing pretty well. But there's clearly room for improvement.

Remember: If just reduction of cardiovascular risk is your interest, then a lackadaisical attitude towards these issues might work. But if your interest is elimination of risk and reversal of atherosclerotic plaque, then it pays to go the extra mile. In this case, knowing your omega-3 index and omega-6:omega-3 ratio might tighten up your program.

The Omega-3 Index: The higher, the better?

6. October 2009 William Davis (26)
So you take a few fish oil capsules every day and eat fish once or twice a week. What is the blood and tissue level of omega-3 fatty acids generated by your habits?

A number of variables enter into the equation. For instance, if you take fish oil capsules, what is the concentration of omega-3 fatty acids? How well are they absorbed? After absorption, how effectively are omega-3 fatty acids incorporated into cell membranes?

Even if you take fish oil supplements, it is hard to know just how much you’ve increased blood levels. It is now possible to measure the amount of omega-3 fatty acids in your bloodstream, a value called the omega-3 index. Too little and you might still be at high risk for cardiovascular events.


The Omega-3 index and sudden cardiac death

Two large studies have demonstrated that higher omega-3 blood (the level in red blood cells, or RBCs) levels were associated with reduced likelihood of sudden cardiac death. The risk for sudden cardiac death was 10-fold higher for the lowest omega-3 RBC levels compared to the highest.



Harris WS 2008; adapted from Siscovick DS et al 1995 and Albert CM et al 2002
(The omega-3 Index was derived from whole blood omega-3 levels, which correlate with RBC omega-3 levels, and are thus “estimated.”)


What’s the average omega-3 RBC level for Americans? Most Americans have omega-3 RBC levels in the 2.5-4.0% range, consistent with the tallest bars at the left and associated with greatest risk for sudden cardiac death. People with heart disease can have levels less than 1%. Some authorities propose that this new measure be called the omega-3 index.

Subsequent studies have shown that the omega-3 index has greater power to discriminate who will have a heart attack or die from sudden cardiac death better than any other common laboratory measure of coronary risk, including LDL cholesterol, HDL cholesterol, triglycerides, total cholesterol to HDL ratio, homocysteine, and c-reactive protein.

Just as hemoglobin A1c offers a 3-month look into blood glucose levels, the omega-3 index reflects your long-term omega-3 intake. The quantity of RBC omega-3s also closely parallels the quantity of omega-3s in heart tissues.


What is an ideal omega-3 index?

The above studies relating RBC omega-3 levels and sudden cardiac death suggest that a level of 6.3-7.3% is associated with far fewer fatal events?but events are not eliminated at this level. Is there even greater benefit with levels higher than 6.3-7.3%?

A recent analysis of females from the Harvard School of Public Health suggested that RBC omega-3 levels as high as 8.99% were still associated with non-fatal heart attack (myocardial infarction), compared to 9.36% in those without heart attacks. This suggests that even higher levels are necessary to prevent non-fatal events.

Should we target 10%? 12%? Maybe higher? Any higher and we are toeing the level achieved by the Inuits, the “Eskimoes” of Greenland, northern Canada and Alaska who have been observed to have a low rate of heart disease.


What’s your omega-3 index?

The appreciation of the importance of omega-3 fatty acids marks one of the greatest health revelations of the last 50 years. We can now measure it.

The ability to measure the proportion of omega-3 fatty acids in red blood cells may provide yet another means for all of us to further reduce risk for cardiovascular events.

If you are interested in knowing your omega-3 index, we are now making the fingerstick test kits available by going here.

Vitamin D increased my cholesterol

2. October 2009 William Davis (38)
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.

28. September 2009 William Davis (20)
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

24. September 2009 William Davis (17)
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

23. September 2009 William Davis (20)
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.

And you thought gasoline was expensive

2. June 2009 William Davis (5)
In 1995, the Palmaz coronary stent was introduced, the brainchild of Drs. Julio Palmaz and Richard Schatz. Medical device manufacturer, Johnson & Johnson, priced the device at $2500 per stent.

Let's put this into perspective: At just 0.05 grams per 15 millimeter stent, that put the price of the common stainless steel used to manufacture the stent at $22,650,000 per pound.

Only after several competing stents finally made it to market did J&J reduce its price to its bargain price of $1200, or $10,872,000 per pound. And to think that most of us were shocked to find out that the U.S. military paid $200 for a hammer.

Since 1995, a competitive market for stents has developed, pushing prices down. Now, you can purchase a brand-new coronary stent for as little as $4,000,000 per pound.

Medical device manufacturers have been guilty of a degree of greed that would make many Wall Street bankers blush. That's why I call medical devices "the industry of infinite markups."

"Hey buddy, wanna buy some exorphins?"

31. May 2009 William Davis (18)
Dr. Christine Zioudrou and colleagues at the National Institutes of Mental Health got this conversation going back in 1979 with their paper, Opioid peptides derived from food proteins: The exorphins.

Exorphins are exogenously-derived peptides (i.e., short amino acid sequences obtained from outside the body) that exert morphine-like properties. Mimicking the digestive process that occurs in the gastrointestinal tract using the gastric enzyme, pepsin, and hydrochloric acid (stomach acid), Zioudrou et al isolated peptides from wheat gluten with morphine-like activity. They followed this research path because of the apparent association of wheat and mental illness.

In the bioassays used, wheat-derived exorphins competed successfully with the endogenous opiate, met-enkephalin. Interestingly, casein-derived (i.e., casein milk protein) exorphins were also identified that also displayed opiate-binding activity, though less powerfully. The morphine-like activity was also blocked by the drug, naloxone (the same stuff given to people exposed to morphine overdose).

Among the many devastating effects of celiac disease , the immune disease that develops from wheat gluten exposure, are mental and emotional effects, such as anxiety, fatigue, mental "fog," depression, bipolar illness, and schizophrenia, that disappear with removal of gluten. Many parents of autistic children also advocate wheat-free diets for similar reasons.

Among the many wonderful comments posted on the last Heart Scan Blog post, "I can't do it," was Anne's:

I am not the Anne in your post, but I was addicted to wheat. It was my favorite food. I lived on and for breads. Then I discovered I was gluten sensitive and I did go through a withdrawal of about 4 days. After 4 days I noticed my health problems were disappearing. Depression, brain fog and joint pain are 3 of the many symptoms that disappeared. That was 6 yrs ago.

Tell Anne that I had dreams about bread in the beginning - they will pass. Now the donuts, breads, cookies and cakes in the stores and at work don't even look good. In fact, I don't like the smell of bread anymore. It takes time, but the cravings do pass.


Combine wheat"s exorphin-driven addictive potential with its flagrant blood sugar-increasing properties, and you have a formula that:

1) makes you fat
2) increases likelihood of diabetes, and
3) makes you want to keep on doing it.

Reminds me of nicotine.

My personal view: I have absolutely no remaining doubt that wheat products have no place in the human diet. Not only does the research provide a plausible basis for its adverse health effects, but having asked hundreds of people to remove it from their habits has yielded consistent and remarkable health benefits. Just read the reader comments here and here.

"I can't do it"

30. May 2009 William Davis (20)
Anne sat across from me, bent over and sobbing.

"I can't do it. I just can't do it! I cut out the breads and pasta for two days, then I start dreaming about it!

"And my husband is no help. He knows I'm trying to get off the wheat. But then he brings home a bunch of Danish or something. He knows I can't help myself!"

Having asked hundreds of people to completely remove wheat from their diet, I witness 30% of them go through such emotional and physical turmoil, not uncommonly to the point of tears. For about 10-20% of people who try, it is as hard as quitting cigarettes.

Make no mistake about it: For many people, wheat is addictive. It meets all the criteria for an addictive product: People crave it, consuming it creates a desire for more, lacking it triggers a withdrawal phenomenon. If wheat were illegal, there would surely be an active underground trafficking illicit bagels and pretzels.

Withdrawal consists of fatigue and mental fogginess that usually lasts 5-7 days. Just like quitting smoking, wheat withdrawal is harmless but no less profound in severity.

People who lack an addictive relationship with wheat usually have no idea what I'm talking about. To them, wheat is simply a grain, no different than oats.

But wheat addicts immediately know who they are. They are the ones who can't resist the warm dinner rolls served at the Italian restaurant, need to include something made of wheat at every meal, and crave it every 2 hours (matching the cycle of blood sugar peaks and valleys, the "valley" triggering the craving). When they stop the flow of immediately-released glucose that comes from wheat (with blood sugar peaks that occur higher and faster than table sugar), irresistible cravings kick in. Then watch out: They'll bite your hand off if you reach for that roll before they do.

Break the cycle and the body is confused: Where's the sugar? The body is accustomed to receiving a constant flow of easily-digested sugars.

Once the constant influx of sugars ceases, it takes 5-7 days for metabolism to shift towards fat mobilization as a source of energy. But along with fat mobilization comes a shrinking tummy, reducing the characteristic wheat belly.

If you try to quit smoking, you've got "crutches" like nicotine patches and gum, Zyban, Chantix, hypnosis, and group therapy sessions. If you try and quit wheat, what have you got? Nothing, to my knowledge. Nothing but sheer will power to divorce yourself from this enormously destructive, diabetes-causing, small LDL-increasing, inflammation-provoking, and addictive substance.

Spontaneous combustion, vampires, and goitrogens

26. May 2009 William Davis (17)
What do the following have in common:

Lima beans
Flaxseed
Broccoli
Cabbage
Kale
Soy
Millet
Sorghum?

They are all classified as goitrogens, or foods that have been shown to trigger goiter, or thyroid gland enlargement. Most of them do this either by blocking iodine uptake in the thyroid gland or by blocking the enzyme, thyroid peroxidase. This effect can lead to reduction in thyroid hormone output by the thyroid gland, which then triggers increased thyroid stimulating hormone (TSH) by the pituitary; increased TSH acts as a growth factor on the thyroid, thus goiter.

Add to this list of goitrogens the flavonoid, quercertin, found in abundance in red wine, grapes, apples, capers, tomatoes, cherries, raspberries, teas, and onions. Most of us obtain around 30 mg per day from our diet. Quercetin, often touted as a healthy flavonoid alongside resveratrol (e.g., Yang JY et al 2008), has been shown to be associated with reduced risk for heart disease and cancer. Many people even take quercetin as a nutritional supplement.

Quercetin has also been identified as a goitrogen (Giuliani C et al 2008).

What to make of all this?

Most of these observations have been made in in vitro ("test tube") preparations or in mice. Rabbits who consume a cabbage-only diet can develop goiter.

How about humans? The few trials conducted in humans have shown little or no effect. In most instances, the adverse effects of goitrogens have been eliminated with supplemental iodine. In other words, goitrogens seem to exert their ill thyroid effects when iodine deficiency is present. Restore iodine . . . no more goitrogens (with rare exceptions).

Should we as humans adopt a diet that avoids apples, grapes, tomatoes, red wine, tea, onions, soy etc. on the small chance that we will develop goiter?

I believe that we should avoid these common food-sourced goitrogens with as much enthusiasm as we should be worried about spontaneous combustion of humans or the appearance of vampires on our front porches. We are as likely to suffer low thyroid activity from quercetin or other "goitrogens" as we are to experience the "mitochondrial explosions" that are purported to set innocent people afire.

Magnesium and you-Part II

25. May 2009 William Davis (17)
Blood magnesium levels are a poor barometer for true body (intracellular) magnesium.

Only 1% of the body’s magnesium is in the blood, the remaining 99% stored in various body tissues, particularly bone and muscle. If blood magnesium is low, cellular magnesium levels are indeed low—very low.

If blood magnesium is normal, cellular or tissue levels of magnesium may still be low. Unfortunately, tissue magnesium levels are not easy to obtain in living, breathing humans. In all practicality, a blood magnesium test only helps if it’s low, while normal levels don’t necessarily mean anything and may provide false reassurance.

Short of performing a biopsy to measure tissue magnesium levels, several signs provide a tip-off that magnesium may be low:

• Heart arrhythmias—Having any sort of heart rhythm disorder should cause you to question whether magnesium levels in your body are adequate, since low magnesium levels trigger abnormal heart rhythms. In fact, in the hospital we give intravenous magnesium to quiet down abnormal rhythms.
• Low potassium— Low magnesium commonly accompanies low potassium. Potassium is another electrolyte depleted by diuretic use and is commonly deficient in many conditions (e.g., excessive alcohol use, hypertension, loss from malabsorption or diarrhea). Like magnesium, potassium may not be fully replenished by modern diets.
• Muscle cramps— Magnesium regulates muscle contraction. Leg cramps, or “charlie-horses”, painful vise-like cramps in calves, fingers, or other muscles, are a common symptom of magnesium deficiency. (Leg cramps that occur with physical activity, such as walking, are usually due to atherosclerotic blockages in the leg or abdominal arteries, not low magnesium.)
• Migraine headaches—Reflective of magnesium’s role in regulating blood vessel tone, low magnesium can trigger vascular spasm in the blood vessels of the brain. In some emergency rooms, they will actually administer intravenous magnesium to break a migraine.
• Metabolic syndrome—Magnesium plays a fundamental role in regulating insulin responses. Metabolic syndrome (low HDL, high triglycerides, small LDL, high blood pressure, increased blood sugar, excessive abdominal fat, etc.) is triggered by insulin responses gone awry and is clearly linked to low magnesium levels.

The absence of any of these tell-tale signs does not necessarily mean that tissue levels of magnesium are normal.

Then how do you really know? There really is no easy, available method to gauge body magnesium. As a practical solution, we therefore have aimed for maintaining serum levels of >2.1 mg/dl or RBC magnesium (a surrogate for tissue levels) of >6.0 mg/dl. (Going too high is not good either, so occasional monitoring really helps. However, I've only seen this once in a psychotic woman who drank ungodly amounts of magnesium-containing antacids for no apparent reason; she almost ended up on a respirator due to respiratory suppression by the magnesium level of 11 mg/dl!)

In all practicality, because of magnesium’s crucial role in health, its widespread deficiency in Americans, and the growing depletion of magnesium in water, supplemental magnesium is necessary for nearly everyone to ensure healthy levels.

More on magnesium to come.

Lethal Lipids II

22. May 2009 William Davis (7)
I call the combination of low HDL, small LDL, and lipoprotein(a) "lethal lipids," since the trio is an exceptionally potent predictor for heart disease. Uncorrected, the combination is a virtual guarantee of heart disease.

Ed is a perfect example of someone who came to my office recently with this pattern. His starting values:

HDL: 34 mg/dl

Small LDL: 78% of total LDL
NMR: Small LDL 1655 nmol/L; total LDL particle number 2122 nmol/L)

Lipoprotein(a): 205 nmol/L


The atherogenicity, or plaque-causing potential, of this pattern was reflected in Ed's heart scan score of 2133.

You can readily see that, of this combination, only HDL cholesterol would be adequately identified through conventional lipid testing. Small LDL and lipoprotein(a) need to be specifically measured via lipoprotein testing.

And, contrary to the drug industry's "statin drugs for everybody" motto, this pattern, while improved with statin therapy, is not shut off.

Specific correction of each abnormality is required. For instance, niacin addresses all three: increases HDL, reduces small LDL, and (usually) reduces lipoprotein(a). A standard low-fat diet makes this pattern worse by reducing HDL, increasing small LDL, and (usually) increasing lipoprotein(a).

"You've got 10 minutes"

20. May 2009 William Davis (0)
There's a new trend in office healthcare in Milwaukee: Time-restricted office visits.



I'm told by several physicians who are employed by a major healthcare system here in town that they are peridically watched--physically watched by an administrator--to make sure that they do not exceed the allotted 10 minutes of time. My cardiologist colleagues, I gather, were at first incredulous at such intrusions into their practices, but apparently had no choice: They were employees.



Goiter, goiter everywhere

20. May 2009 William Davis (25)
The results of the recent Heart Scan Blog poll are in.

The question:

Do you used iodized salt?

The responses:

Yes, I use iodized salt every day
94 (28%)

Yes, I use iodized salt occasionally
56 (16%)

No, I do not use any iodized salt
41 (12%)

No, I use a non-iodized salt (sea salt, Kosher)
126 (37%)

No, I use a non- or low-sodium substitute
15 (4%)


Thanks for your responses.

If only 28% of people are regular users of iodized salt, that means that the remainder--72%--are at risk for iodine deficiency if they are not getting iodine from an alternative source, such as a multivitamin or multimineral.

Even the occasional users of salt can be at risk. The common perception is that occasional use is probably sufficient to provide iodine. This is probably not true and not just because of the lower quantity of ingestion. Occasional users of salt tend to have their salt canister on the shelf for extended periods. The iodine is then lost, since iodine is volatile. In fact, iodine is virtually undetectable four weeks after a package is opened.

In my office, now that I'm looking for them much more systematically and carefully, I am finding about 2 people with goiters every day. They are not the obvious grotesque goiters of the early 20th century (when quack therapies like the last post, the Golden Medical Discovery, were popular). The goiters I am detecting are small and spongy. Yesterday alone I found 5 people with goiters, one of them visible to the eye and very distressing to the patient.

It seems to me that iodine deficiency is more prevalent than I ever thought. It is also something that is so simple to remedy, though not by increasing salt intake. Kelp tablets--cheap, available--have been working quite well in the office population. My sense is that the Recommended Daily Allowance of 150 mcg per day for adults is low and that many benefit from greater quantities, e.g., 500 mcg. What is is the ideal dose? To my knowledge, nobody has yet generated that data.

Thyroid issues being relatively new to my thinking, I now find it incredible that endocrinologists and the American Thyroid Association are not broadcasting this problem at the top of their lungs. This issue needs to be brought to the top of everyone's attention, or else we'll have history repeating itself and have goiters and thyroid dysfunction galore.

For more on this topic, see the previous Heart Scan Blog post, "Help keep your family goiter free."

Goiter and the Golden Medical Discovery

17. May 2009 William Davis (19)

Thick neck, or goitre . . . consists of an enlargement of the thyroid gland, which lies over and on each side of the trachea, or windpipe, between the prominence known as "Adam's apple" and the breast bone. The tumor gradually increases in front and laterally, until it produces great deformity, and often interferes with respiration and the act of swallowing. From its pressure on the great blood vessels running to and from the head, there is a constant liability to engorgement of blood in the brain, and to apoplexy, epilepsy, etc.

The causes of the affection are not well understood. The use of snow water, or water impregnated with some particular saline or calcareous matter, has been assigned as a cause. It has also been attributed to the use of water in which there is not a trace of iron, iodine, or bromine. . . The disease is often due to an impeded circulation in the large veins of the neck, from pressure of the clothing, or from the head being bent forward, a position which is often seen in school children.


Treatment

We have obtained excellent results in many cases, not too far advanced, by a method of treatment which consists in the employment of electrolysis. . . Many cases at the present time are operated upon with entire success.

Those who are afflicted with this disease and unable to avail themselves of special treatment cannot do better than to take Doctor Pierce's Alterative Extract, or Golden Medical Discovery, and apply over the skin around the tumor, night and morning, the following, which may be prepared at any drug store:

Resublimed Iodine--One dram
Iodide of Potassium--Four drams
Soft Water--Three ounces 


Apply to the tumor, twice daily, with feather or camel hair pencil.

Magnesium and you-Part I

15. May 2009 William Davis (11)
If this were 10,000 B.C., you'd get your drinking water from streams, rivers, and lakes, all rich in mineral content. Humans became reliant on obtaining a considerable proportion of daily mineral needs from natural water sources.

21st century: We obtain drinking water from a spigot or plastic bottle. Pesticides and other chemicals seep into the water supply. Municipal water purification facilities have intensified water purification in most communities to remove contaminants like lead, pesticide residues, and nitrates. (For a really neat listing of the water quality of various cities, the University of Cincinnati makes this data available.)

But intensive water treatment also removes minerals like calcium and magnesium.

Many people have added water filters or purifiers to their homes,, like reverse osmosis and distillation, that are efficient at extracting any remaining minerals, converting “hard” into “soft” water. In fact, manufacturers of such devices boast of their power to yield pure water free of any “contaminant,” minerals like magnesium included. The magnesium content of water after passing through most commercial filters is zero.

Modern enthusiasm for bottled water has compounded the problem. Americans consumed a lot of bottled water, nearly 8 billion gallons last year. In the U.S., nearly all bottled water has little or no magnesium.

The result is that we can no longer rely on drinking water to provide magnesium. The Recommended Daily Allowance (RDA)—the amount required to prevent severe deficiency—for magnesium is 420 mg per day for men, 320 mg/day for women. In cities with the highest magnesium water content, only 30% of the RDA can be obtained by drinking two liters of tap water per day. In most cities, only a meager 10–20% of the daily requirement can be obtained. That leaves between 70–90% that needs to come from other sources. As a result, the average American ingests substantially less than the RDA.
