Excessive Heart Procedures Makes New York Times Headline

18. August 2006 William Davis (0)

One example of flagrant cardiac procedure excess has made New York Times headlines:

Heart Procedure Is Off the Charts in an Ohio City
The number of angioplasties performed in Elyria is so high that Medicare is starting to ask questions.

(The full article can be accessed through the New York Times website at http://www.nytimes.com/2006/08/18/business/18stent.html?pagewanted=2&ei=5094&en=b81be5f43f98a99b&hp&ex=1155960000&partner=homepage)

Cardiologists in little Elyria, Ohio, about a 30-minute drive west of Cleveland, do more coronary angioplasties and insert more stents than any other location in the U.S.--four times more than the national average, three times more than the Cleveland average. They perform even more than the recently-indicted cardiologist in Louisiana, who performed twice the national average of procedures.

The Times article, part of a series about financial incentives in medical care, provides a responsible and incredibly balanced report on the situation in Elyria. I have to give them credit, because from the eyes of a colleague (myself), this looks like blatant and extreme profiteering: "cathing for dollars".

I find it outrageous that this group of cardiologists claims that they have some special insight into heart care that justifies this extraordinary reliance on heart procedures. There's bound to be variation in practice patterns, but this is so outside the norm that I believe criminal behavior will be exposed. In fact, I believe that even the "norm", or average, rate of procedures is also excessive.

This is symptomatic of the perverse equation in heart disease care. If there's money to be made in major heart procedures, who wants to bother with prevention? Programs like the Track Your Plaque program present real potential to stop coronary heart disease in its tracks for many, if not most, participants--but don't expect to hear about it from your cardiologist. Don't expect to hear about it from the increasingly hospital-employed primary care physician.

Hopefully, media exposure like that in the New York Times is just the beginning of a public re-analysis of not only what's wrong with medicine today, but recognition of the tremendous power in preventive strategies when everyone stops being so enamored with hospital-based procedures. CT-based heart scanning that ignites your heart disease prevention program is your way to dodge the mainstream obsession with procedures.

More on "Bio-identical hormones" and Wyeth Pharmaceuticals

18. August 2006 William Davis (0)

In October 2005, Wyeth petitioned the FDA, requesting that it completely ban the bioidentical alternatives that women have been using in ever-increasing numbers to achieve optimal hormone balance. With bioidentical replacement therapy clearly reducing its market share, Wyeth asked the FDA to outlaw all compounded bioidentical hormone formulations that compete with its own discredited drugs. If Wyeth is successful, then menopausal women will have no choice other than to take potentially life-threatening hormone drugs or to forgo hormone replacement therapy altogether, thus enduring the physically and emotionally debilitating effects of menopause-induced hormone depletion.

For more commentary on Wyeth Pharmaceutical's outrageous and brazen petition to the FDA to bar prescription "bio-identical" hormones, i.e., hormones that are identical to natural human forms, read Life Extension's article, Health Freedom Under Attack!
Drugmaker Seeks to Deny Access to Bioidentical Hormones

This well-researched article is in the August, 2006 issue of Life Extension Magazine. The article can also be accessed online at http://www.lef.org/magazine/mag2006/aug2006_cover_attack_01.htm

or go to www.lef.org and click on the August, 2006 issue.

The author, Dave Tuttle, details the baseless arguments raised by Wyeth, a pathetic and amazingly selfish act in the name of protecting profits for Premarin, their prescription agent. It's bad enough to be selling this worthless drug. It's even worse--criminal, in my mind--to try to stamp out our right to have a physician write a prescription for a pharmacy to mix up hormones identical to that humans produce, individualized to our needs.

If you are as angry about this as I am, please go to the Life Extension online reprint that provides access to the International Academy of Compounding Pharmacists website to send the FDA an e-mail describing your opinion, or go to www.iacprx.org.

How accurate is LDL cholesterol?

17. August 2006 William Davis (0)

Watch TV and you'd get the impression that the world revolves around LDL cholesterol: Commercials for Lipitor, Zetia, Vytorin, etc., all drugs to reduce cholesterol (total and LDL). Your doctor looks first and often only at LDL cholesterol.

If there's so much attention paid to LDL, how accurate is it? 100%? 90%? 80%?

Well, it varies widely. Occasionally, it's truly accurate, but most of the time it's miserably inaccurate . Every single day, I see people with LDL cholesterols that underestimates true (measured) LDL by 40%, 50%, and even over 100%. In other words, LDL cholesterol might be 120 mg/dl by the conventional method, but the genuine measured value might be 160 mg/dl, or even 240 mg/dl. It can be that far off--and it's not rare.

The converse can occasionally be true, though rarely in my experience: that conventional LDL overestimates true LDL. I saw someone in the office today like this, with a conventional LDL of 142 mg/dl but a true measured LDL of 115 mg/dl. I may see one or two more people like this the rest of this year.

Why is LDL so inaccurate? Several reasons:

--LDL in most labs is calculated, not measured. The "Friedewald calculation" derives LDL by substracting HDL and triglycerides (divided by 5) from total cholesterol. The higher triglycerides are, especially above 150 mg/dl, the more inaccurate the calculation becomes. As HDL drops below 50 mg/dl, this also introduces greater and greater inaccuracy.

--LDL particles vary in size. A more accurate representation and measure of LDL's dangers are therefore found in measures of LDL particle number , rather than a weight-based measure or calculation. LDL particle number can be measure as just that, LDL particle number (NMR), or as apoprotein B, the protein in LDL that occurs one apoB per LDL.

I liken conventionally calculated LDL cholesterol to a broken speedometer. You simply won't have an accurate measure of how fast you're going, though you may have a ballpark sense. But try telling that to the state patrol.

Or, as a cardiologist colleague said to me in a similar conversation about LDL: "Well, it's better than nothing!"

The lesson: If you're interested in plaque control, and control or reduction of heart scan score, you need a measured LDL, preferably LDL particle number by NMR or an apoprotein B. Another option is "direct" LDL.

Green tea: friend or faux?

15. August 2006 William Davis (0)

The www.HealthCastle.com website is a helpful website on healthy eating that sends out a free newsletter. The content is all produced by licensed dietitions and nutritionists. Although I don't agree with everything said on the site, there's still some good information.

I'm a fan of green tea. Although I believe the effects are relatively modest (weight reduction, cholesterol reduction, anti-oxidation, etc., with theaflavin and/or green tea as a beverage,) they alerted me to the fact that the Lipton Green Tea product is one you should steer clear of. Here are their comments:

"More like Soft drink than Green Tea!With 200 calories, 13 teaspoons of added sugar and a long list of artificial ingredients, Lipton Iced Green Tea is more like a bottle of soft drink than tea, in our opinion."

The Lipton website lists the ingredients:

Water, high fructose corn syrup, citric acid, green tea, sodium hexametaphosphate, ascorbic acid (to protect flavor), honey, natural flavors, phosphoric acid, sodium benzoate (preserves freshness), potassium sorbate (preserves freshness), calcium disodium edta (to protect flavor), caramel color, tallow 5, blue1.

An 8 oz serving yields 21 grams of sugar. If you drink the full 20 oz. bottle (not hard to do!), that yields 52.5 grams of sugar! You will also notice that the second ingredient listed after water is high fructose corn syrup. This ingredient, you may recall, causes triglycerides to skyrocket, causes an insatiable sweet tooth, and is a probable contributor to obesity and diabetes.

In their defense, the Lipton people do also offer a sugar-free alternative without the excessive sweeteners and empty calories.

Do the Lipton products offer the same kind of benefits from green tea catechins (flavonoids) offered by freshly brewed teas? This product has not been formally tested by an independent lab to my knowledge, though, in general, commercially prepared and bottled teas tend to have dramatically less catechin/flavonoid content compared to brewed. (The USDA website provides access to an extraordinary collection of flavonoid food content at their USDA Database for the Flavonoid Content of Selected Foods - 2003. You'll find it at http://www.ars.usda.gov/Services/docs.htm?docid=6231.)

I think the HealthCastle people got it right: Brew your own, making sure to steep for at least 3 minutes. Alternatively, a green tea or theaflavin supplement provides many of the benefits. (Theaflavin has been used in trials at doses of 375 to 900 mg per day.) An in-depth report on green tea will be coming in a future Special Report on the www.cureality.com Membership website.

The Track Your Plaque guide to getting grotesquely overweight

15. August 2006 William Davis (0)

If you'd like to gain huge quantities of weight, here's a number of helpful tips:

1) Follow the advice of food manufacturers and eat the products they label "healthy", or "heart healthy", or "part of a nutritious breakfast" etc., like Shredded Wheat cereal, pretzels ("a low-fat snack"!), low- or non-fat salad dressings.

2) Cut your morning calorie intake by skipping breakfast.

3) Hang around with other heavy people. They will confirm that it's okay to be overweight.

4) Call walking your dog "exercise".

5) Get a sedentary desk job. Use your swivel desk chair to scoot about whenever possible, rather than getting up to do things.

6) Say "I've worked hard all week long. Weekends are for relaxing, not for physical activities. I deserve a rest."

7) Eat foods without thinking about it: Eat chips while watching football, eat while on the phone, daydream over the sink.

8) Eat to provide comfort when stressed.

9) Eat foods that have sentimental value, whether or not they're good for you: Freshly-baked cakes that remind you of Mom, Pop Tarts that you used to carry in your lunchbox when you were a kid, hot dogs just like Dad would buy at the baseball stadium.

10) Cut back on sleep and generate insatiable starch cravings.

11) Stack your shelves at home with great variety. That way, you'll always have something to suit your mood.

12) Say to your spouse: "It's none of your damn business what I eat! I'm a grown man/woman!" Prove it by over-indulging in obviously unhealthy foods.

13) Tell yourself that you're just too busy to pay attention to food choices. Just grab whatever you can out of a convenience store or vending machine.

See, it's easy! And that just a start.

Of course, I don't really want you to do any of these things. But if you see yourself in any of the above, and you're struggling with weight, you should seriously rethink your approach.

Your heart scan is just a "false positive"

15. August 2006 William Davis (0)

I've seen this happen many times. Despite the great media exposure and the growing acceptance of my colleagues, heart scans still trigger wrong advice. I had another example in the office today.

Henry got a CT heart scan in 2004. His score: 574. In his mid-50s, this placed him in the 90th percentile, with a heart attack risk of 4% per year. Henry was advised to see a cardiologist.

The cardiologist advised Henry, "Oh, that's just a 'false positive'. It's not true. You don't have any heart disease. Sometimes calcium just accumulates on the outside of the arteries and gives you these misleading tests. I wish they'd stop doing them." He then proceeded to advise Henry that he needed a nuclear stress test every two years ($4000 each time, by the way). No attempt was made to question why his heart scan score was high, since the entire process was outright dismissed as nonsense.

I'm still shocked when I hear this, despite having heard these inane responses for the past decade. Of course, Henry's heart scan was not a false positive, it was a completely true positive. I'm grateful that nothing bad happened to Henry through two years of negligence, though his heart scan score is likely around 970, given the expected, untreated rate of increase of 30%.

The cardiologist did a grave disservice to Henry: He misled him due to his ignorance and lack of understanding. I wish Henry had asked the cardiologist whether he had read any of the thousands of studies now available validating CT heart scans. I doubt he's bothered to read more than the title. The cardiologist is lucky (as is Henry) that nothing bad happened in those two years.

Do false positives occur as the cardiologist suggested? They do, but they're very rare. There's a rare phenomenon of "medial calcification" that occurs in smokers and others, but it is quite unusual. >99% of the time, coronary calcium means you have coronary plaque--even if the doctor is too poorly informed to recognize it.

What's better than a heart scan?

13. August 2006 William Davis (0)

Do you know what's better than a heart scan?

Two heart scans. No other method can provide better feedback on the results of your program.

Say you've made efforts to correct high LDL; lost weight to raise HDL and reduce small LDL; added soluble fibers, nuts, and dramatically reduced wheat products; take fish oil, vitamin D, and follow a flavonoid-rich diet. Has it worked?

After a year or so of your program, that's when another heart scan can give you invaluable feedback on whether it's been successful. I tell my patients that it's relatively easy to correct lipid and lipoprotein abnormalities. The difficult part is to know when it's good enough. Is your LDL of 67 mg/dl and HDL of 50 mg/dl good enough? Another heart scan score is the best way I know of to find out.

Variation in plaque growth differs hugely from one person to another, even at equivalent lipoprotein values. Why? Lots of reasons. Humans are inconsistent day to day. Lipoproteins, being a snapshot in time and not a cumulative value, change somewhat from day to day. There's also the possibility of unmeasured, unrecognized factors that influence coronary plaque growth. We may not be smart enough to identify these hidden factors yet. But your heart scan score will incorporate the effects of these hidden factors.

Ideally, we aim for zero growth in plaque (no change in score) or a reduction. But, particularly in the first year, 10% or less plaque growth is still a good result that predicts much reduced risk of heart attack. More than 20% per year and your program needs more work--or else you know what's ahead.

Lipids are snapshots in time; heart scans are cumulative

12. August 2006 William Davis (0)

Let me paint a picture. It's fictional, though a very real portrait of how things truly happen in life.

Michael is an unsuspecting 40-year old man. He hasn't undergone any testing: no heart scan, no lipids or lipoproteins. But we have x-ray vision, and we can see what's going on inside of him. (We can't, of course, but we're just pretending.) Average build, average lifestyle habits, nothing extraordinary about him. His lipids/lipoproteins at age 40:

--LDL cholesterol 150 mg/dl
--HDL cholesterol 38 mg/dl
--Triglycerides 160 mg/dl
--Small LDL 70% of all LDL

At age 40, with this panel, his heart scan score is 100. That's high for a 40-year old male.

Fast forward 10 years. Michael is now 50 years old. Michael prides himself on the fact that, over the past 10 years, he's felt fine, hasn't gained a single pound, and remains as active at 50 as he did in 40. In other words, nothing has changed except that he's 10 years older. His lipids and lipoproteins:

--LDL cholesterol 150 mg/dl
--HDL cholesterol 38 mg/dl
--Triglycerides 160 mg/dl
--Small LDL 70% of all LDL

Some of you might correctly point out that just simple aging can cause some deterioration in lipids and lipoproteins, but we're going to ignore these relatively modest issues for now.)

Lipids and lipoproteins are, therefore, unchanged. Michael's heart scan score: 1380, or an approximate 30% annual increase in score. (Since Michael didn't know about his score, he took no corrective/preventive action.)

My point: If we were to make our judgment about Michael's heart disease risk by looking at lipids or lipoproteins, they would'nt tell us where he stood with regards to heart disease risk. His lipids and lipoproteins were, in fact, the same at age 50 as they were at age 40. That's because measures of risk like this are snapshots in time.

In contrast, the heart scan score reflects the cumulative effects of life and lipids/lipoproteins up until the day you got your scan.

Which measure do you think is a better gauge of heart attack risk? I think the answer's obvious.

11. August 2006 William Davis (0)

The recognition of the metabolic syndrome as a distinct collection of factors that raise heart disease risk has been a great step forward in helping us understand many of the causes behind heart disease.

Curiously, there's not complete agreement on precisely how to define metabolic syndrome. The American Heart Association and the National Heart, Lung, and Blood Institute issued a concensus statement in 2005 that "defined" metabolic syndrome as anyone having any 3 of the 5 following signs:

Waist size 40 inches or greater in men; 35 inches or greater in women

Triglycerides 150 mg/dL or greater (or treatment for high triglycerides)

HDL-C <40 mg/dL in men; <50 mg/dL in women (or treatment for reduced HDL-C)

Blood Pressure >130 mmHg systolic; or >85 mmHg diastolic (or drug treatment for hypertension)

Glucose (fasting) >100 mg/dL (or drug treatment for elevated glucose)

Using this definition, it has become clear that meeting these criteria triple your risk of heart attack.

But can you have the risk of metabolic syndrome even without meeting the criteria? What if your waste size (male) is, 36 inches, not the 40 inches required to meet that criterion; and your triglycerides are 160, but you meet none of the other requirements?

In our experience, you certainly can carry the same risk. Why? The crude criteria developed for the primary practitioner tries to employ pedestrian, everyday measures.

We see people every day who do not meet the criteria of the metabolic syndrome yet have hidden factors that still confer the same risk. This includes small LDL; a lack of healthy large HDL despite a normal total HDL; postprandial IDL; exercise-induced high blood pressure; and inflammation. These are all associated with the metabolic syndrome, too, but they are not part of the standard definition.

I take issue in particular with the waist requirement. This one measure has, in fact, gotten lots of press lately. Some people have even claimed that waist size is the only requirement necessary to diagnose metabolic syndrome.

Our experience is that features of the metabolic syndrome can occur at any waist size, though it increases in likelihood and severity the larger the waist size. I have seen hundreds of instances in which waist size was 32-38 inches in a male, far less than 35 inches in a female, yet small LDL is wildly out of control, IDL is sky high, and C-reactive protein is markedly increased. These people obtain substantial risk from these patterns, though they don't meet the standard definition.

To me, having to meet the waist requirement for recogition of metabolic syndrome is like finally accepting that you have breast cancer when you feel the two-inch mass in your breast--it's too late.

Recognize that the standard definition when you seen it is a crude tool meant for broad consumption. You and I can do far better.

What role DHEA?

9. August 2006 William Davis (2)

DHEA, the adrenal gland hormone, has suffered its share of ups and downs over the years.

Initially, DHEA was held up as the fountain of youth with hopes of turning back the clock 20 years. Such extravagant dreams have not held up. But DHEA can still be helpful for your program.

All of us had oodles of DHEA in our bodies when we were in our 20s and 30s. Gradually diminishing levels usually reach nearly blood levels of around zero by age 70.

In our heart disease prevention program, of course, we aim to stop or reduce your CT heart scan score. Does DHEA reduce your score? No, it most certainly does not. But it can be helpful for gaining control over some of the causes behind coronary plaque.

For instance, DHEA can:

--Help reduce abdominal fat and increase muscle mass (slightly)
--Provide more physical stamina.
--Boost mood.
--It may modestly reduce some of the phenomena associated with the metabolic syndrome (high blood pressure, high blood sugar, high insulin, low HDL, small LDL, etc.)

In my experience, people who feel better do better on their overall program. If you're always tired and run down and run out of steam by 3 pm, I won't see you riding your bicycle outdoors or at the aerobics class. But if you're bursting with energy until you put your head on the pillow, you're more inclined to walk, bike, dance, play with the kids, dance, take Tai Chi, etc.

Some downsides to DHEA: Some people experience aggression. Backing off on the dose usually relieves it. Also, sleeplessness. Taking your DHEA in the morning usually fixes it.

The dose is best tailored to your age and blood levels. People less than 40 years old should not take DHEA. The older you are, the higher the dose, though we rarely ever have to exceed 50 mg per day. If you've never had a blood level and your doctor refuses to obtain one, 25 mg per day is a reasonable dose (10-15 mg in women 40-50 years old). It's always best to discuss your supplement use, particularly agents like DHEA, with your doctor.

Coenzyme Q10 and statin drugs

23. July 2006 William Davis (0)

Although drug manufacturers claim that muscle side effects from statin drugs occurs in only around 2% or people or less, my experience is very different.

I see muscle weakness and achiness develop in the majority of people taking Lipitor, Crestor, Zocor, Vytorin, etc. I'd estimate that nearly 90% of people get these feelings sooner or later.

Thankfully, the majority of the time these feelings are annoyances and do not lead to any impairment. Full-blown muscle destruction is truly rare--I've seen it once in over 10 years and thousands of patients.

The higher the dose of statin drug and the longer you take it, the more likely you're going to have muscle aches.

I experienced a strange phemomenon myself today. I worked outdoors for about 4 hours, pulling weeds, digging in the dirt, spreading topsoil. (I have an area of overgrowth in the front yard.) Admittedly, I worked pretty hard and it was a warm, humid day.

I was sore, as you'd expect at age 49. But, much more than that, I was exhausted--my muscles ached and I had barely enough strength to get up the stairs.

Hoping for some relief, I took an extra dose of coenzyme Q10. I usually take 50-100 mg per day. Today, when I felt this overwhelming muscle fatigue, I took an additional 200 mg. Within 10 minutes, I felt a surge of energy. It was, in fact, a perceptible, quite dramatic feeling.

I am thoroughly convinced, through my own experiences on Lipitor (I have a high LDL particle number despite a healthy lifestyle, among other abnormalities), and the experiences of many other people, that coenzyme Q10 can be an extremely useful tool to minimize the muscle aches and weakness of the statin drugs.

If you do indeed need to take one of these agents, coenzyme Q10 is worth knowing about. Supplementing coenzyme Q10 has, for me, been a real lifesaver. For many people, LDL reduction is a crucial part of their heart scan score control program. In my experience, many of them would not be able to take the drug without eozyme Q10.

Blast your LDL with oat bran and almonds

21. July 2006 William Davis (1)

Nearly all of us can use an extra boost in reducing LDL cholesterol. We have a large number of people, in fact, who have reduced LDL into the Track Your Plaque range of 60 mg/dl or less without the use of statin cholesterol-reducing drugs.

Oat bran is among my favorite ways to reduce LDL. Three tablespoons per day is a really effective method to drop your LDL around 20 points. There's twice the beta glucan (soluble, or "viscous", fiber)in oat bran, as compared to the more popular oatmeal. Add oat bran to anything you can think of: yogurt, cottage cheese, vegetarian chili, oatmeal, top desserts with it, etc. Some people struggle to find oat bran in the grocery store. Most health food stores that sell bulk products will have oat bran, usually less than a $1 per pound. Many grocery stores will also have an oat bran hot cereal along with the Cream of Wheat and oatmeal. That's okay, provided the only ingredient is oat bran--no added sugars, etc.

Another dynamite method to reduce LDL 10-20 points is adding raw almonds to your daily food choices. One or two handfuls per day works great. We find it at Sam's Club for around $12.99 for a 3 lb. bag. The plentiful fibers and monounsaturates in almonds keep you full and satisified, take the edge off your sweet tooth, and even blunt the blood sugar rise caused by other foods.

Both these foods are also great ways to combat the metabolic syndrome. Since both fiber-rich oat bran and almonds slow the release of sugars into the blood, blood insulin level is also reduced. This results in a happy cascade of less small LDL, increased HDL, and a reduction in inflammation.

All these wonderful effects contribute to inching you closer to success: dropping your heart scan score.

Pre-diabetes with normal blood sugar

20. July 2006 William Davis (0)

We pay special attention to pre-diabetes, in all its varied manifestations, in the Track Your Plaque program. This is because these factors are potent instigators of coronary plaque growth.

Early in the Track Your Plaque program we ignored these measures. After all, this is a program for heart disease risk reduction, not for mangement of diabetes. But we saw explosive rates of plaque growth when pre-diabetic factors were not controlled--even when cholesterol and related factors were under excellent control.

It became increasingly clear that factors associated with pre-diabetes needed to be managed, as well. This includes small LDL, increased blood sugar, high blood pressure, increased inflammation (as CRP).

Many people, however, have normal blood sugars (100 mg/dl or less) with a high blood insulin level (>10 microunits/ml). (This blood test is available in most laboratories.) This means that they have early resistance to insulin. The pancreas, the source of insulin, responds to the body's unresponsiveness to insulin by increasing insulin production.

Increased blood insulin with normal blood sugar will drive production of higher triglycerides, a drop in HDL, creation of small LDL, and inflammation--and coronary plaque growth, as evidenced by increasing CT heart scan score.

Blood insulin levels can be very effectively dropped by weight loss; exercise; reduction of processed carbohydrates like breads, pretzels, and breakfast cereals; and increased raw nuts and oat products; and vitamin D replacement to normal levels. Drug manufacturers are desperately trying to make this a mandate for drug treatment (Actos, Avandia), but are encountering resistance, since most people without overt diabetes don't want to take diabetic medication (rightly so!).

You and your doctor should consider insulin as a factor to track, especially if you have small LDL, low HSL, or high triglycerides, or any of the other manifestations listed above.

Sometimes small LDL is the only abnormality

19. July 2006 William Davis (0)

Janet is a 58-year old schoolteacher. At 5 ft 3 inches and 104 lbs, she had barely an ounce of fat on her size-2 body. For years, Janet's primary care physician complimented her on her cholesterol numbers: LDL cholesterol values ranging from 100 to 130 mg/dl; HDL cholesterol of 50-53 mg/dl.

Yet she had coronary disease. Her heart scan score: 195.

Lipoprotein analysis uncovered a single cause: small LDL. 95% of all of Janet's LDL particles were in the small category. What was surprising was that this pattern occurred despite her slender build. Weight is a powerful influence on the small LDL pattern and the majority of people with it are overweight to some degree. But not Janet.

How did she get small LDL if she was already at or below her ideal weight? Genetics. Among the genetic patterns that can account for this pattern is a defect of an enzyme called cholesteryl-ester transfer protein, or CETP. This is the exact step, by the way, that is blocked by torcetrapib, the new agent slated for release sometime in future (The manufacturer, Pfizer, is apparently going to sell this agent only packaged in the same tablet as Lipitor. This has triggered an enormous amount of criticism against the company and they are, as a result discussing marketing torcetrapib separately.)

Also note that Janet had a severe excess of small LDL despite an HDL in the "favorable" range. (See my earlier conversation on this issue, The Myth of Small LDL at http://drprevention.blogspot.com/2006/06/myth-of-small-ldl.html.)

With Janet, weight loss to reduce small LDL was not an option. So we advised her to take fish oil, 4000 mg per day; niacin, 1000 mg per day; vitamin D, 2000 units per day; use abundant oat bran and raw almonds, both of which suppress small LDL. This regimen has--surprisingly--only partially suppressed her small LDL pattern by a repeat lipoprotein analysis we just performed. We're hoping this may do it, i.e., stop progression or reduce her heart scan score.

The lesson: Small LDL is a very potent pattern that can be responsible for heart disease, even if it occurs in isolation. And, contrary to conventional thinking, small LDL can occur as an independent abnormality, even when HDL is at favorable levels.

Report from Washington II

16. July 2006 William Davis (0)

Today's discussions at the Society for Cardiovascular Computed Tomography (SCCT) focused on atherosclerotic "plaque characterization".

As CT scanners get better and better at imaging the various components of plaque, some fascinating issues emerge:

--CT heart scans provide insights into what exactly is contained in an individual's atherosclerotic plaque that are not often provided even during heart catheterization. In other words, CT heart scanning is, in many instances, superior to heart catheterization, since it provides images of the artery wall, not just the internal contents.

--Progression (i.e., increase) in heart scan score is a powerful predicter of heart attack risk. Dr. Matthew Budoff of UCLA argued persuasively that the annual rate of increase in score is probably the most accurate measure of risk available, superior to cholesterol and calculated measures like the Framingham risk score.

--Coronary calcium scoring remains the best method to gauge total plaque throughout the entire coronary tree. In a person free of symptoms, the risk of a cardiac "event" (heart attack, death, procedures) is low and additional imaging (like CT angiography) is generally unnecessary.

Dr. Budoff, among the true thought leaders in CT heart scanning, also recounted his perspective on the history of heart scans. He noted that the questions asked through the years have evolved:

1995-2000 Should we do coronary calcium scans?

2000-2002 Do high or low risk patients benefit from coronary calcium scoring?

2003-2004 What is the better scanner, EBT or MDCT?

2006 How often should we perform coronary calcium imaging?

I believe that Dr. Budoff summarizes wonderfully where the Track Your Plaque programs fits into the overall scheme of things: Serial (repeated)CT heart scans to gauge progression or reversal is the wave of the future. We shouldn't just be interested in identifying persons at risk for heart attack. We should also be interested in showing the person at risk exactly how to reduce or eliminate that risk.

Report from Washington

14. July 2006 William Davis (0)

I'm presently attending the Society for Cardiovascular Computed Tomography meetings in Washington, DC, along with 500 of my colleagues. It's exciting to see how interest in CT scanning for heart disease has balloonned in the past couple of years.

Several trends are noticeable today, based on the content and tone of the discussions:

--CT scanning of the heart, and imaging in general, is just getting started. In other words, the capabilities for CT scanners and other devices to detect heart disease (coronary and otherwise) are where the gasoline engine was in the 19th century. Scanning is getting faster, easier, safer, and more precise. Just as few people in 1905 could have predicted that automobiles would be computer-enhanced, high-speed, ubiquitous devices with several per household, the potential for CT imaging for heart disease is truly in its infancy.

--CT coronary angiography (so-called "64-slice CT scans") are not screening tests for hidden coronary disease in people without symptoms. I was grateful that this point has been made and reiterated by several speakers, as this is consistent with our views. Simple CT heart scans for coronary calcium scoring, in contrast, are screening tests. When the radiation exposure of CT angiograms are reduced to tolerable levels, then they may be used as screening tests. We are probably 3-4 years away from this point.

--Both stress testing and heart catheterizations will be partially replaced by CT scanning. In particular, over the next decade, you will see a dramatic drop in unnecessary catheterizations, i.e,, far less people saying "I had a heart cath but they told me that it was normal."

There has been heavy focus on applications of CT scanning for acute settings, particularly the emergency room and hospitals.

What has surprised me is that there is virtually no conversation whatsoever about the preventive uses of CT heart scanning. So far, only Dr. Daniel Berman of UCLA has shown that he has "seen the light": CT scans are a crucial tool for identification of early coronary plaque, and this tells us whether prevention is necessary and with what intensity.

There has been, however, no discussion at all about quantification of plaque in a program of reversal. Perhaps that should come as no surprise, given the imaging-technology focus of this convention. For most of my colleagues, prevention is also not terribly interesting. Identification and treatment of acute disease like impending heart attack is.

Of course, applying the information from your CT heart scan to empower you in a program and reversal is what the Track Your Plaque program is all about. I hope you see the light. I admit that it's not always easy to follow what we are advocating here. Perhaps not too different than telling someone in his horse-drawn buggy that one day he'll be driving a sleek car with onboard computerized mapping, air-conditioning, and micro-chips to modulate engine performance. He's probably tell us we're nuts.

I'll continue to update if any news relevant to our interests crops up in these meetings.

What about the Track Your Plaque failures?

14. July 2006 William Davis (0)

I’d love to tell you that the Track Your Plaque program track record is of 100% success. It’s not.

It is very successful. But we’ve had some people who have failed and failed BIG. These are the people who've undergone bypass surgery, received one or more stents, or had heart attacks. Lesser failures are the people who’ve had large, undesirable increases in heart scan scores of >30% in one year. (The expected rate of increase in your heart scan score without preventive efforts is 30% per year, on average.)

What can we learn from those failures? There were several characteristics that stand out among this small group:

· Non-compliance--meaning they just didn’t stick with it. They started out right but then rapidly lost interest in maintaining all the pieces of the program and neglected their fish oil, niacin, gain weight, etc. Matthew did this and ended up with three stents to his left anterior descending. His slow start was due to skepticism that the program worked and just plain forgetfulness.

· Extreme stress--One of our earliest failures was a 38-year old man whose heart scan score doubled in one year, despite doing everything right. But three family members, all close to him, died within the space of six months, including his mother and a brother. I regard this as one of those instances in which we were powerless, unfortunately, though it is a graphic example of the power of unresolved stress and grief.

· Having a “better way”--These are the couple of people who were convinced that they had a better way to control their heart scan score. David firmly believed that his two dozen supplements and exercise program would drop his score. Instead, they permitted a 42% increase. Lee relied exclusively on chelation, along with several supplements of his own design. Lee had three-vessel bypass surgery.

· Starting too late--Gerome started with a score of 1179, but also was having chest pressure with emotional stress. His stress test was abnormal, with the entire upper half of his heart not receiving blood with exercise on a stress nuclear study (“anterior ischemia”). Gerome received four bypass grafts. Unfortunately, Gerome never really had a chance to engage in the Track Your Plaque program, since his health and safety were in jeopardy as soon as he started.

Have we had any big failures of people who did everything right, were compliant, were not subject to extreme stress (more than just job stress, or financial worries), didn’t neglect the basic requirements of the Track Your Plaque program, and had sufficient time (at least 6 months to 1 year)? No, thankfully, we have not.

No one who has stuck to the program has had a big failure.

Be smarter than your cardiologist

12. July 2006 William Davis (0)

“Do you need a stent?”

Sad to say, but that sentence condenses the wisdom of over 90% of practicing cardiologists.

Prevention of heart disease means take Lipitor or some other statin and cutting the saturated fat in your diet. That’s it. Maybe throw in exercise.

Regression of coronary plaque? That phrase has only entered the conversation since the AstraZeneca-supported trial of Crestor succeeded in achieving 8% regression of plaque (Track Your Plaque Members: See News) as demonstrated by intracoronary ultrasound.

In other words, in the minds of my colleagues, it can’t be true until a drug company tells them it’s true. It’s beyond me why this brainwashing of otherwise intelligent people has occurred, but it is blatantly evident in practice.

Fish oil is another example. The spectacular benefits of fish oil have been known for 20 years. But only recently has it become a “mainstream” practice to recommend fish oil, largely because a drug manufacturer has put a preparation through the rigors of FDA approval (Omacor) and is now marketing directly to physicians. All of a sudden, fish oil is a good thing? No, it’s just achieved legitimacy in the eyes of practitioners because it graces marketing literature.

If you’re reading this, you’re likely interested in coronary plaque regression using the only tool available for you to measure, track, and regress coronary plaque: CT heart scans. Intracoronary ultrasound will achieve the same goal, but it is an invasive procedure performed at heart catheterization, involves threading a wire and imaging probe all the way down the artery, involves real risk of tearing the inner lining of the artery, and is costly (around $14,000-$20,000 for the entire package). Do it every year? That’d be nuts.

If you’re thinking about coronary plaque regression, using fish oil, concerned about patterns like low HDL and small LDL, aware of the vitamin D deficiency issue as a coronary risk factor, etc., you are far more aware than the vast majority of practicing cardiologists. They are interested in what new brand of anti-coagulant to use during their heart catheterization (because the product representative gushes about the new agent—only $1200 a dose!). Or, they are interested in gaining the procedural skills to put in a new device like a biventricular pacemaker. Regress/reverse coronary plaque? What for?

You already know that a conversation about coronary plaque reversal will not be obtained in your cardiologist’s office. Your family practice doctor or internist? Fat chance! Knee arthritis, pap smears, pneumovax inoculations, sore throats, gout, back pain—they’re spread far too thin to know anything more than the most superficial amount about coronary plaque control. Most know nothing.

That’s where we come in. That’s our mission: Educate people about the extraordinary tools that you have available to you, all in the cause of control or reversal of coronary plaque.

Why am I here?

11. July 2006 William Davis (0)

Frank came to the office for an opinion, sent by his (proactive) family physician.

"I really don't know why I'm here, to be honest."

Two years earlier, Frank had a heart attack, survived and received two stents to his circumflex coronary artery. He now took Zocor and his LDL cholesterol was a reasonably favorable 89 mg, total cholesterol 183 mg.

"I walk with my wife every other day. I've been avoiding fish fries. You'll never see me eat fast food."

Frank was correct: If we were going to engage in the conventional approach to coronary disease, Frank was on the right track. We would have postponed his next heart attack or procedure by a couple of years. Stroke, aneurysm, and other atherosclerotic manifestations would be set back, likewise, a few years.

Would Frank have profound control over his disease? Absolutely not. In fact, his disease had probably advanced a huge amount just in the two years since his stents were placed and he was on his "prevention" program. Without his current effort, his coronary plaque would be expected to grow 30% per year. On Zocor and his modest lifestyle efforts, plaque growth was probably in the 14-28% per year range.

So I explained the unique Track Your Plaque approach to Frank. First, we start with a CT heart scan to establish where he was starting. Although he had two stents in his circumflex artery, we still had two other arteries (LAD, right coronary) to score and track.

We then attempt to identify all hidden causes of his heart disease and then correct them.

Of course, Frank had multiple hidden causes:

--HDL too low at 38 mg/dl
--Small LDL-severe, in fact, with 95% of all LDL particles in the small category
--Triglycerides too high
--Excesses of several triglyceride-containing particles (VLDL, IDL)
--Pre-diabetes--Frank had both a borderline high blood sugar and a high insulin level. This is a sure-fire stimulus to coronary plaque growth.
--A severe deficiency of vitamin D (<20 ng/ml)
--An excessivelyhigh blood pressure during exercise--With a blood pressure of 190/102 on the treadmill.

There were others(!), but that was the bulk of the causes behind Frank's coronary disease.

Once Frank recognized that there was indeed a huge panel of hidden causes for heart disease, not just too much fat in his diet and LDL cholesterol, he jumped into the program head first.

The message: The conventional approach is absurdly oversimplified, a certain path to failure for the majority of people. Even if you don't have known coronary disease like Frank, but just have a heart scan score >zero, the same principles apply to you.

Catheterization to “define coronary anatomy”

10. July 2006 William Davis (0)

Gary is an avid jogger. On an average day, he runs 5-6 miles at a good clip. On two occasions recently, however, Gary experienced an ache in his left shoulder at mile 4. It was a toothache-like feeling, but he kept on going without difficulty.

Gary also had a heart scan score of 370.

Upon hearing of Gary’s score and his shoulder sensation, the cardiologist who saw him advised a heart catheterization “to define coronary anatomy”. (This is a real incident.)

What exactly does that mean? Why would Gary’s cardiologist need to define it?

In my view, this is an absurd notion. No one needs to “define coronary anatomy”. This catch-all phrase is commonly used to justify heart procedures. I believe what the cardiologist is saying is that it’s the easiest (for the cardiologist) and perhaps most generously reimbursed method to determine whether Gary’s symptoms are warning of an impending heart attack or not.

The problem is that the question can also be answered quite well by doing a stress test. Though not perfect diagnostic tests, stress tests are useful when symptoms are present that are doubtful in nature. Gary’s left shoulder ache could have been related to his heart, but the likelihood was that it was not. A stress test would have answered the diagnostic question quite adequately.

Instead, this man was subjected to an invasive test that was likely unnecessary. This happens dozens, if not hundreds, of times per day just around here. Nationwide, it is an epidemic of malpractice.

There are, indeed, times when a person should proceed directly to a heart catheterization. This is commonly and appropriately performed when a person develops unstable heart symptoms, such as chest discomfort or breathlessness at rest while not doing anything physical, or if the frequency is increasing, or if a stress test shows an important abnormality. There is no question that heart procedures can be lifesaving at times.

The problem is that thousands of people every year are scared into these procedures inappropriately. Beware!

It doesn't matter what I eat!

9. July 2006 William Davis (0)

"How are your food choices?" I asked.

"What does it matter, doc? I take Lipitor. Doesn't that take care of it? I eat what I want!"

So declared Matthew. What he "wanted" was pretty much the diet of a teenager: pizza, cheeseburgers, soft drinks, snacks. His "beer belly" (visceral fat) gave it away. So did his blood work that showed flagrant lipoprotein abnormalities--small LDL, an HDL of 37 mg, and a severe after-eating flood of fat represented by increased "intermediate-density lipoprotein" (IDL).

Like many people, Matthew had been persuaded (or chose to believe) that LDL cholesterol was the sole cause for heart disease. Lipitor was therefore was all he needed. It must be great--how else could they afford all those slick TV commercials?

Well, it is definitely not true. In fact, with the persistence of Matthew's abnormal lipoprotein patterns, we should expect his heart scan score to continue to grow by 30%--the very same rate of increase as if he were taking nothing.

Specifically, Lipitor and drugs like it do not:

--Raise HDL.

--Correct or reduce the proportion of small LDL.

--Block after-eating flood of fat, nor do they accelerate clearance of unhealthy fats persisting in the bloodstream after eating.

Yes, what you eat does have real consequences, even if you take a statin drugs. In fact, the foods you ingest have a remarkably rapid and dramatic effect on what your blood contains. Any diabetic who checks his/her blood sugar knows this. They eat a slice of whole wheat toast and watch their blood sugar skyrocket.

Mind what you eat. Make it enjoyable, of course. But drugs do not provide impunity.

People with higher scores need to try harder

8. July 2006 William Davis (0)

Sam is a 69-year retired physician. He was thoroughly enjoying retirement: golf, travelling, going out to dinner two or three times a week, spending weekends with his grandchildren. His lifestyle tended towards overindulgence, but he managed to stay fit and trim. At 6 ft 1 inch, he weighed 194 lbs and could still run 3 miles without too much difficulty. Not as good as his marathon-running days, but still not too bad for 69.

Sam's heart scan score in 2003 was a concerning 1983--extensive plaque. His doctor wasn't much help in interpreting the scan and so Sam simply chose to ignore it.

A chance conversation with a physician friend 18 months later made Sam think that perhaps this shouldn't be ignored. That's when he came to my office.

I find that sometimes the best way to motivate someone to take action is to demonstrate just how fast plaque grows if action isn't taken. So I advised Sam to get another scan first, since 18 months had passed. His score: 2441, or a 23% increase.

Sam was now starting to catch on. We made several changes in his prevention program (starting from virtually nothing). He did undergo a stress nuclear (thallium type) of test, which he passed without difficulty--normal blood flow in all heart territories despite the extensive plaque.

But, for some reason, Sam simply allowed himself to drift back to old habits: poor choices in food, overindulging in hard liquor, missing his fish oil and other supplements, and his medication, sometimes up to several days a week.

Sam started having unusual feelings in his chest. He described a sort of nervousness along with skipped heart beats. So we repeated a stress test. This time, a large area of reduced blood flow in the front of his heart ("anterior left ventricle") was detected. Sam ended up receiving three stents in a difficult procedure.

The moral: If you're starting out with a lower heart scan score of, say, 100 or 200, maybe you'll get by without trying too hard--maybe. But if your score is higher, say, several hundred or in the thousands, you got to try harder.

You're starting later in the process. Your disease will allow you very little slack. Let your guard down and it will get you. Control over your plaque is, indeed, very possible--we do it all the time. Score reduction is also possible. But your effort must be more serious and consistent.

Money can't buy health

6. July 2006 William Davis (1)

Fallen Enron CEO, Kenneth Lay, was pronounced dead early this a.m. after suffering a heart attack.

Mr. Lay apparently had no history of heart disease and there's been no indication that symptoms provided any warning. His death was therefore classified as "sudden cardiac death".

Yet here's a man previously worth hundreds of millions of dollars with access to any test or medical system he desired--many times over. Even more recently, with his wealth reduced following his legal troubles, he and his wife managed to put away $4 million dollars to ensure an income from the interest through annuities, untouchable by the courts.

Detecting Mr. Lay's heart disease would have cost him around a few hundred dollars or whatever it costs for a CT heart scan in his city. This would have alerted his (hopefully knowledgeable) doctor that he was a time-bomb. Pile on all the stress he'd been suffering, whether deserved or no, and the diagnosis would have required little thought.

Instead, Mr. Lay has joined the thousands of Americans who will die this year because of failing to get a simple, 30-second test that costs one-tenth the cost of a stress test. Mr. Lay wasn't as lucky as former President Bill Clinton, whose doctors likewise blundered their way through and missed obvious levels of heart disease.

All Mr. Lay needed was better information: get a heart scan, then follow a program of prevention like the Track Your Plaque program. You may not have hundreds of millions of dollars, but you have the information on how to not follow in Ken Lay's footsteps. Track Your Plaque--and stay alive.

What's important, what's not in your plaque-control program

6. July 2006 William Davis (0)

Sometimes it's hard to know what is really important in your plaque-control or plaque-reducing efforts.

There are, indeed, crucial make-it-or-break-it factors that are necessary to gain control over plaque. If you hope to stack the odds of reducing your heart scan score as much as possible in your favor, then fish oil, vitamin D, 60-60-60 in the way of standard lipids, elimination of small LDL, etc. -- all the elements of the Track Your Plaque program--are necessary.

But there's lots of things that sidetrack people. I spend much of my day fielding questions from patients about all the things that either provide very little benefit for plaque control, or provide none at all.

Among the things that we have found to be too weak or useless for plaque control, or are "non-issues", include:

--Caffeine--Go ahead and enjoy a couple cups a day (though not a pot). The effect is too trivial to make much difference.

--Hawthorne--Yes, it may dilate coronary arteries modestly, but not enough to make any difference.

--Garlic--with the possible exception of a specific preparation called Aged Garlic Extract (an acqueous, non-oil-based, extract from Kyolic), garlic's effects are too tiny to help, e.g., drop in blood pressure 1-2 points. Use it, but don't expect much. Aged Garlic Extract may be an exception, in that a single study from UCLA suggested specific effects on slowing coronary plaque growth. We await more info on this.

--Anti-oxidants--There is no shortage of extravagant claims about the benefits of anti-oxidants. Unfortunately, there's very little human exerience with pine bark extract, pycnogenol, grapeseed extract, and so on. Is the purported benefit from anti-oxidation or through some other means, e.g., enhancement of nitric oxide synthase? No data.

--Policosanol--If you've followed the Track Your Plaque Special Reports, you already know what a disappointment this agent has been, despite the too-good-to-be-true clinical data. It doesn't work.

--"No-flush niacin"--Unfortunately, no flush, no effect. This high-priced supplement is still sold widely in the U.S. despite its complete lack of efficacy. It does not work in humans. (It works great in rats!)

Track Your Plaque continues to try to be the arbiter of truth in what works, what doesn't in truly stopping or reversing your coronary plaque. The proof positive? Stopping or dropping your heart scan score.

Protecting the right to use bio-identical hormones in your heart disease prevention program

4. July 2006 William Davis (0)

If you've been following the Track Your Plaque program, you know that we are advocates of "bio-identical hormones", i.e., hormone replacement using forms that are identical to the naturally-occuring human form.

In other words, we find it criminal that pharmaceutical manufacturers continue to promote use of non-identical hormones despite a probable increased side-effect and complication profile (a la Premarin). This unhappy situation persists because bio-identical hormones cannot be patent protected, meaning profits cannot be protected. Synthetic hormones can be patented and profits protected, thus their popularity among drug companies.

If that's not bad enough, Wyeth Pharmaceuticals--maker of synthetic hormone preparations, Premarin and Prempro--has filed an FDA petition to disallow the use of bio-identical hormones as prepared and dispensed by "compounding pharmacies". These are specialty pharmacies that mix and dispense hormones like estrogens (human estradiol, estriol, and estrione) and testosterone. They do so only with a doctor's prescription. Most are members of the Professional Compounding Centers of America (www.pccarx.com), a professional organization devoted to promoting quality-control over compounding practices.

Compounding pharmacies are occasionally guilty of compounding some suspect preparations. Witness the Fentanyl lollipops of 2002 in which the pain medication, Fentanyl, was put into lollipops for patients with chronic pain. This posed obvious dangers to any children who unsuspectingly ate the lollipops.

But the majority of compounding pharmacies are not guilty of such exotic practices. Most are simply pharmacies who might, for instance, mix a specific dermatologic preparation according to the orders of a dermatologist. Likewise with bio-identical hormones.

We have extensive experience with such a pharmacy in Madison, Wisconsin, the Women's International Pharmacy. They have filled hundreds of hormone prescription for us. They are responsible in their dispensing practices, in our experience. In fact, they have been at least as good, if not better, than other pharmacies we've dealt with.

We believe in protecting our rights to prescribe and you to use the choice of hormone preparations you and your doctor desire. This should include bio-identical hormones. The transparent profit motive from Wyeth should raise the hairs on your neck.

If you would like to post your comment to the FDA, there's a little time left. The folks at Womens' International Pharmacy have made it easy by posting links on their website. Go to http://www.womensinternational.com and just follow the instructions.

Here's a sample of some of the objections citizens have raised to Wyeth's petition:

I have been taking bioidentical hormones for two years. Bioidentical Hormones have been a great relief to me without the risk. I consult with my Physician who prescribes bio-identical hormones specifically for me, and my pharmacist prepares them. Without this medication and I would not be able to sleep; I would not be able to work due to the constant hot flashes. Without this medication, I find that I have less tolerance and I am considerably disagreeable. I also have problem with my memory without them. I want the bioidentcial hormones for the health benefits they provide. I urge you to not be swayed by Wyeth's petition. The product Premarin made by Wyeth, is made from pregnant horses not natural sources. Wyeth's hormones have been shown to cause cancer. I would not expect my government and its officials to submit to the highly funded petitioning of a pharmaceutical company who product is threatened by bioidentcial hormones. I do not expect my government to approved Wyeth's petition and leave me no choice of bioidentcial hormones and only the choice of Wyeth's cancer causing drugs Preamrin and Prempro. I ask that the FDA reject Wyeth's petition Docket #2005P-0411.

Another petitioner writes:

As a woman I take exception to Wyeth accusing the Compounding Pharmacy industry of unsafe practices. As a citizen of the United States I expect the FDA to stand up for my rights and the rights of all women who have found or in the future may seek consistent, safe and effective treatment with bioidentical hormones. Eliminating options by bowing to a large pharmaceutical company like Wyeth is not in the public interest and would deprive hundreds of thousands of American women from access to bioidentical hormones. Synthetic hormone replacement has been proven unequivocally unsafe in a government sponsored study and should not be forced as the sole treatment option for women. I hereby request the FDA rule against Wyeth's request. The FDA should not close down the bioidentical option of healthcare. I welcome studies of bioidentical hormones even though they are already FDA-approved and have been working effectively for decades. We already have the proof - hundreds of thousands of women, who over the past two decades have chosen bioidentical hormones based on their physicians' assessments. They are living proof that bioidentical hormones are safer and more effective and reliable than synthetic hormone drugs.

A physician and user of bio-identical hormones writes:

Wyeth, the filer of this complaint, is trying to prevent women from being able to choose less expensive compounded options for hormone replacement. There is medical evidence that in modifying the structure of their drugs (such as Premarin and Prempro) so that they could be patented, they may have introduced factors that cause the health risks identified in the Women's Health Initiative. This complaint appears to be filed for commercial purposes because of the market share that has shifted from Wyeth's products to bio-identical products from compounding pharmacies. If the complaint were upheld, patients and their doctors would not have a choice in hormone treatments. Wythe's commercial strategy of trying to eliminate the 'competition' from compounding pharmacies is against the public interest and in the interest of its own corporate profits. Women and their doctors should be able to choose between patented formulations such as those offered by Wyeth, bioidentical formulas available from compounding pharmacies, and no hormone treatment. I have been taking bio-identical hormones for several years and have had excellent results in improving my symptoms. I have been unable to take other synthetic hormones in the past, and am very concerned that my best treatment option will be taken away.

If you get a 64-slice CT coronary angiogram

3. July 2006 William Davis (0)

With new 64-slice CT scanners popping up everywhere nowadays, be sure to get your heart scan with it.

The new scanners do indeed provide wonderful images of the coronary arteries. But, say you have a 20% blockage in one artery by a coronary angiogram generated on one of these devices. What will you do in 1, 2, or 3 years when you want to know if you have progressed? Should you have the CT angiogram repeated?

Well, if you did you'll be exposed to a large dose of radiation--appropriate for a diagnostic test, but not for a screening test. The radiation exposure is not that different from undergoing a full conventional cardiac catheterization, or up to 100 chest x-rays.

"20% blockage" is also, contrary to popular opinion, not a quantitative measure. It is just an estimate of the diameter reduction at one spot. That number says nothing about the lengthwise extent of plaque. It also says nothing about the potential for "remodeling", the phenomenon of artery enlargement that occurs as plaque grows. In other words, if you had another CT coronary angiogram a year later and was told that your blockag was still 20%, in reality you could have had substantial plaque growth but it would not be reflected in that value.

People will come to me after having a CT angiogram for an opinion. Unfortunately, I send them back to their scan center to get a simple coronary calcium score. That measure is easy, quantitative, precise, and can be repeated yearly if necessary to track progression. (Track Your Plaque--I hope most of you get this by now.) Some physicians poke fun at the heart scan, or calcium, score--it's old, boring, only a measure of hard plaque. None of that's true. The coronary calcium score is a measure of total plaque (hard and soft). And when you are empowered to learn how to control and reduce your score, then it's the most exciting number in your entire health program!

Don't fall for the hype. If you go to a scan center and they insist on a 64-slice CT scanner, or if your doctor orders one, you should insist on getting a calcium score out of the test. Just ask. If they refuse, go somewhere else. Centers that refuse to generate a score have one thing on their mind: identifying people with severe blockages sufficient to obtain the downstream financial bonanza--angioplasty, stents, and bypass surgery.

If you have hypertension, think Lp(a)

2. July 2006 William Davis (0)

Clair has coronary disease.

Clair first came to attention at age 57 when she suffered a large heart attack involving the front of her heart (the "anterior wall") two years ago. Her cardiologist implanted a drug-coated stent. Her doctors advised her to "cut the fat" in her diet, exercise, and take Lipitor.

One year later, she required a stent to another artery (circumflex). At this point, Clair was thoroughly demoralized and terrified for her future. Her first heart attack left her heart muscle with only 50% of normal strength.

She came to my office for another opinion. Of course, one of the first things we did was to identify all causes of her heart disease. No surprise, Clair had 7 new causes not previously identified, including low HDL (37 mg/dl), a severe small LDL particle pattern (75% of all particles were small), and Lp(a).

Her blood pressure was also 190/88, despite her relatively slender build and 3 medications that reduced blood pressure. That's a Lp(a) effect: Exagerrated coronary risk along with unexpected hypertension that often seems inappropriate.

In fact, I saw several patients just this week with lipoprotein(a), Lp(a), and exagerrated high blood pressure (hypertension). It's not that uncommon.

Though it has not been described in the medical literature, our experience is that hypertension is a prominent part of the entire Lp(a) "syndrome".

Lp(a) is responsible for much-increased potential for coronary disease (coronary plaque). It increases in importance as estrogen recedes in a woman (pre-menopause and menopause) and testosterone in a man, since both hormones powerful suppress Lp(a) expression (though why and how nobody knows).

I believe that Lp(a) is also responsible for hypertension that most commonly develops in a persons mid-50s and onwards, often with a vengeance. 3 or 4 anti-hypertensive medications and still not controlled.

Role of l-arginine

L-arginine may be more helpful in this situation than others. L-arginine, recall, is the supply for your body's nitric oxide, a powerful dilator of the body's arteries and thereby reduces blood pressure. We use 6000 mg twice a day, a large dose that requires use of powder preparations rather than capsules.

More reading about l-arginine and nitric oxide is available through Nobel laureate, Dr. Louis Ignarro's book, NO More Heart Disease : How Nitric Oxide Can Prevent--Even Reverse--Heart Disease and Stroke, available at Amazon.com ( http://www.amazon.com/gp/product/0312335814/104-1247258-6443909?v=glance&n=283155).

Will l-arginine truly reverse heart disease on its own? No, I don't believe so. Contrary to Dr. Ignarro's extravagant claims, I find l-arginine a facilitator of plaque regression, i.e, it helps other strategies achieve regression, but it does not achieve regression or reversal by itself. (Note that Dr. Ignarro is a lab researcher who studies rats and has never treated a human being.)

But l-arginine may have special application in the person with lp(a), particularly if hypertension is part of the syndrome.

Note: As always, please note that I talk frankly about l-arginine and other supplements and medications but have no hidden agenda: I am not selling anything, nor am I affiliated with any source/website/store etc. that sells these products. If I advocate something, I do so because I truly believe it, not because I'm trying to sell something. I make this point because so much nonsense is propagated in the media because of profit-motive. That's not true here.

Dr. Ornish: Get with the program!

30. June 2006 William Davis (2)

In the era up until the 1980s, most Americans indulged in excessive quantities of saturated fats: fried chickem, spare ribs, French fries, gravy, bacon, Crisco, butter, etc.

Along came people like Nathan Pritikin and Dr. Dean Ornish, both of whom were vocal advocates of a low-fat nutritional approach. In their programs, fat composed no more than 10% of calories. This represented a dramatic improvement--at the time.

In 2006, a low-fat diet is a perversion of health. It means over-reliance on breads, breakfast cereals, pasta, crackers, cookies, pretzels, etc., the foods that pack supermarket shelves and that now constitute 70-80% of most Americans' diet.

Dr. Ornish still carries great name recognition. As a result, his outdated concepts still gain media attention. The June, 2006 issue of Reader's Digest, in their RDHealth column, carried an interview with Dr. Ornish in which he reiterates his fat-phobia.

However, on this occasion he takes a different tack. This time he rails against the "dangers" of fish oil and omega-3 fatty acids. "I've recently learned that omega-3s are a double-edged sword...In some cases, omega-3s could be fatal."

He goes on to say that, while he believes that fish oil may prevent heart attacks, it has fatal effect if you already have heart disease.

Does this make sense to you?

He's basing his views on a single, obscure study published in 2003 conducted in rural England that showed an increase in death and heart attack on fish oil. Most authorities have not taken these findings seriously, since they are wildly contrary to all other observations and because the study had some design flaws.

Despite the fact that this isolated study runs counter to all other, better-conducted studies seems not to matter to Dr. Ornish.

Clinging to the low-fat concept is like hoping 8-track tapes will make a comeback. It's not going to happen. We enjoyed the benefits while they lasted, appropriate for the era. But now, they're woefully outdated.

The overwhelming evidence is that fish oil provides tremendous benefits with little or no downside. In the Track Your Plaque program, fish oil remains a crucial supplement to gain control over your coronary plaque and stop or reduce your heart scan score. Ignore the doomsday preachings of Dr. Ornish.

(Watch for an article I wrote updating the benefits of fish oil for Life Extension magazine.)

The cholesterol fallacy

29. June 2006 William Davis (0)

Evan spotted the kiosk set up in the middle of the local mall. "Free cholesterol screenings. Know your heart health!" the sign declared.

It was a free cholesterol screening being offered by a local hospital.

The friendly nurse behind the kiosk had Evan fill out a form, then pricked his finger. Five minutes later, she reported to him with a smile, "Sir, your cholesterol is 177--your heart's fine! We get concerned when cholesterol is over 200. So you're in a safe range."

What the nurse failed to recognize is that Evan's HDL was 30 mg, a low value that actually places him at high risk for heart disease. Low HDL also signifies high likelihood of the small LDL particle pattern, a marked predisposition towards pre-diabetes and diabetes, a probable over-reliance on processed carbohydrates in his diet, a dramatically increased probability of hidden inflammation (e.g., elevated C-reactive protein), increased tendency for high blood pressure. . .

In other words, Evan's "favorable" total cholesterol is, in truth, nonsense. It's misleading, falsely reassuring, and provided none of the insight that a real effort might have yielded. Like hippies, tie-dye, other relics of the 1960s, total cholesterol needs to be put to rest. It has served many people poorly and been responsible for countless deaths.

When you see a kiosk or other service like this, even if it's free, run the other way.

"Heart disease a growth business"

29. June 2006 William Davis (0)

So announced a Boston newspaper recently, featuring a story about new heart program at a local hospital.

They were announcing how a hospital had entered the cardiovasculare procedure game and how it would boost their bottom line. The article discussed how the hospital administration was anticipating "a surge in patients from the baby boom generation."

To justify this new program, the article quoted an administrator from another hospital: "Cardiovascular issues is [sic] the number one cause people sought treatment at our hospital."

The hospital featured in the story had spent $13.5 million dollars to develop their program.

Do you think they'll make it back?

You bet they will--many times over. Hospitals are businesses, complete with a bottom line, an expectation of profit and an eye towards growth.

The hospitals in the city where I live (Milwaukee, Wisconsin) are, as in Boston and elsewhere, very aggressive--expanding into new territories, hiring new "salesmen" (physicians), all to capture more marketshare and produce more "product" (your coronary angioplasty, stent, bypass surgery, defibrillator, etc.).

The equation for hospital profits is tried and true. Ignore your heart disese risk and you can help your local hospital grow its business. Neglect to get your heart scan and you can help your hospital pay down its debt. Get a heart scan, then do nothing about it, and you may even justify a pay raise for the hospital administrators for record revenue growth and profit.

Hospitals are a growth business because of the failure of most people and their doctors to 1) identify hidden coronary disease (CT heart scan to obtain your heart scan score), then 2) seize control over it (the Track Your Plaque program or, at least, your doctor's guidance along with your efforts at prevention).

Unless you do so, you are highly likely to help your hospital boost its annual goal for procedures.

Dr. Cannell comments on vitamin D lab tests

14. July 2008 William Davis (9)

As always, Dr. John Cannell of The Vitamin D Council continues to teach us new lessons about vitamin D.

Apparently, Dr. Cannell is swamped with the attention that vitamin D is drawing, largely due to his efforts to publicize the enormous deficiency of Americans and his great talent for articulating the science. The most current newsletter, while a bit haphazard, makes some excellent new points that I reprint here.

(I did not reprint his conversation about "any form of vitamin D" being acceptable. My experience differs: In nearly 1000 patients who have taken vitamin D supplements, my experience is that most tablet forms are inconsistently absorbed, sometimes not absorbed at all. I therefore advocate only use of gelcaps or liquids. I'm told by members of Track Your Plaque, however, that they are witnessing reliable increases in blood levels of vitamin D by taking the powdered form of Bio Tech Pharmacal's product.)

Does it matter what reference lab my doctor uses?

Yes, it might make a huge difference. A number of methods exist to measure 25(OH)D in commercial labs. The two most common are mass spectrometry and a chemiluminescence method, LIAISON. The first, mass spectrometry, is highly accurate in the hands of experienced technicians given enough time to do the test properly. However, in the hands of a normally trained technician at a commercial reference lab overwhelmed with 25(OH)D tests, it may give falsely elevated readings, that is, it tells you are OK when in fact you are vitamin D deficient. The second method, chemiluminescence, LIAISON, was recently developed and is the most accurate of the screening, high throughput, methods; LabCorp uses it. Quest Diagnostics reference lab uses mass spec. Again, both Quest and LabCorp are overwhelmed by 25(OH)D requests. The problem is that the faster the technicians do the mass spec test, the more inaccurate it is likely to be. If your 25(OH)D blood test says "Quest Diagnostics" on the top, do not believe you have an adequate level (> 50 ng/ml). You may or may not; the test may be falsely elevated. Let me give you an example. A doctor at my hospital had Quest Diagnostics do a 25(OH)D. It came back as 99 ng/ml of ergocalciferol. He is not taking ergocalciferol (D2), he has never taken ergocalciferol, only cholecalciferol, and he is not taking enough to get a level of 99 ng/ml, 50 ng/ml at the most. His email to Dr. Brett Holmquist at Quest about why Quest identified a substance he was not taking went unanswered other than to say "any friend of Dr. Cannell's is a friend of ours."

Long story short: if your lab report says "LabCorp" on the top, it is probably accurate; if it says Quest Diagnostic, it may be falsely elevated. While LabCorp has also been overwhelmed with 25(OH)D requests, the LIAISON method they use is relatively easy to do and does not rely on technician skill as much as the mass spec methods do. I'm not saying this because I'm a consultant for DiaSorin, who makes LIAISON, I'm saying it because it is true. If you don't believe me, get Quest to make me an offer to be their consultant at 10 times what DiaSorin is supposed to be paying me ($10,000 per year) and see how fast I turn Quest down. If Quest fixes their test, I'd love to consult. The ironic thing: I've made both Quest and LabCorp lots of money via this newsletter, the website, and by repeatedly telling the press that people need to know their 25(OH)D level, which has contributed to the skyrocketing sales of 25(OH)D blood tests.

Demand for vitamin D tests soars as nutrient's potential benefits touted.

Here you can help. Find out which labs in your town use Quest Diagnostics and which use LabCorp. Have a 25(OH)D test at both labs the same day (you will have to pay for them yourself). Then send both results to the Vitamin D Council address below. If Quest Diagnostics does not fix their 25(OH)D test, the Vitamin D Council will fix it for them.

My doctor prescribed Drisdol, 50,000 IU per week. What is it?

Drisdol is a prescription of 50,000 IU tablets of ergocalciferol or D2. Ergocalciferol is not vitamin D but it is similar. It is made by irradiating ergosterol, which is found in many living things, such as yeast. D2 is not normally found in humans and most studies show it does not raise 25(OH)D levels as well as human vitamin D (cholecalciferol or D3) does. However, Drisdol is a lot better than nothing. The best thing to do, if you are vitamin D deficient, and a human, is to take human vitamin D, cholecalciferol, A.K.A. vitamin D3.

What is the ideal level of 25(OH)D?

We don't know. However, thanks to Bruce Hollis, Robert Heaney, Neil Binkley, and others, we now know the minimal acceptable level. It is 50 ng/ml. In a recent study, Heaney et al enlarged on Bruce Hollis's seminal work by analyzing five studies in which both the parent compound, cholecalciferol, and 25(OH)D levels were measured. It turn out that the body does not reliably begin storing the parent compound (cholecalciferol) in fat and muscle tissue until 25(OH)D levels get above 50 ng/ml. The average person starts to store cholecalciferol at 40 ng/ml, but at 50 ng/ml, virtually everyone begins to store it for future use. That is, at levels below 50 ng/ml, the body is usually using up the vitamin D as fast as you make it or take it, indicating chronic substrate starvation, not a good thing.

I have advanced renal failure and I'm on dialysis, how much vitamin D should I take?

The same as everyone else. Since I have told you about commercial labs ripping you off, let's add some drug companies. Patients with advanced renal failure need activated vitamin D or one of it's analogs, available by prescription. This is very important as their kidneys cannot make enough 1,25-dihydroxy-vitamin D (calcitriol) to maintain serum calcium. However, the rest of their tissues activate vitamin D just fine and when those tissues get enough, and when the kidneys get more vitamin D, the calcitriol spills out into the blood, lowering their need for prescription calcitriol or one of its analogs. The companies that make the analogs don't like that, it means reduced sales. So these companies do nothing, the scientists behind these companies say nothing, and renal failure patients die prematurely from one of the vitamin D deficiency diseases.

When I asked my doctor for a 25(OH)D blood test, he just laughed and said it was all idiotic. What can I do?

Help me unleash the dogs of war, the plaintiff attorneys. If you read about past nutritional epidemics caused by society, such as beriberi or pellagra, you will realize that education alone will take decades. Physicians successfully fought against the idea that thiamine deficiency caused beriberi for decades. However, things are different now. The agents of change in modern America, as obnoxious as they are, are plaintiff attorneys. Once the first malpractice lawsuits claiming undiagnosed and untreated vitamin D deficiency led to breast cancer, autism, heart disease, etc., get past summary judgment, and they will, and end up in front of a jury, and they will, things will change rapidly. One of the main reason physicians do what they do is fear of lawsuits. In a matter of months, arrogance and ignorance will give way to 25(OH)D tests and vitamin D supplementation.

Privileged information

12. July 2008 William Davis (9)

In 1910, taking a person's blood pressure was considered revolutionary, a high-tech practice that was of uncertain benefit.

Dr. Harvey Cushing of Johns Hopkins Hospital in Baltimore had observed a blood pressure device while traveling in Europe, developed by Dr. Sciopione Riva-Rocci. Cushing brought this new technology back with him to the U.S. and promptly promoted its use, convinced that this insight into gauging the forcefulness of blood pressure would yield useful clinical insights.

But, in 1910, practicing physicians rejected this new technology, preferring to use their well-established and widely practiced technique of pulse palpation (feeling the pulse), skeptical that the new tool added value. Medical practice of the day was rich with descriptions of the strength and character of the pulse: pulsus parvus et tardus (the slow rising pulse of aortic valve stenosis), the dicrotic notch of aortic valve closure transmitted to the pulse, the "water-hammer" pulse of aortic valve insufficiency.

Over the next 20 years, however, the medical community finally gave way to the new technique, although only physicians were allowed to use blood pressure devices, as nurses were regarded as incapable of mastering the skills required to perform the procedure properly.

Stethoscopes were also gaining in popularity in the early 20th century, but were also the exclusive province of physicians trained in their use. Nurses were not allowed to use stethoscopes until the 1960s. Even then, nurses were not allowed to call them "stethoscopes," but "nurse-o-scopes" or "assistoscopes," and the nurses' version of the device was manufactured to look different to avoid confusion with the "real" doctor's tool.

And just half a century ago, if you wanted to look at a medical textbook, you would have to go to the library and ask for special permission. The librarian would lower her glasses and look you up and down to determine whether or not you were some kind of pervert. Only then might you be granted permission to peer into the pictures of organs and naked bodies.

Such has been the spirit of medicine for centuries: Medicine and its practices are meant to be secret, the insider knowledge of a privileged few.

Fast forward to 2008: The Information Age has overturned the rules of privileged information. Now you have access to the same information as I do, the same information available to practicing physicians. The playing field has been levelled.

Curiously, while information access has advanced at an instantaneous digital pace, attitudes in medicine continue to evolve at the traditional analog crawl. Many of my colleagues continue to be dismayed at the new public access to health information, belittle patients for excessive curiosity about their health, lament the erosion of their healthcare-directing authority. And while new concepts race ahead as we race towards a wiki-like collective growth in healthcare knowledge, physicians are still mired by their reluctance to abdicate their once-lofty positions as chief holders of secrets.

I believe that this is part of the reason why family doctors and cardiologists have been slow to adopt technologies like heart scans and self-empowering programs like Track Your Plaque: processes that take heart disease prevention away from the hands of physicians and place more control into the hands of the people.

Imagine the horror felt by physicians in 1935 of a young upstart nurse boldly trying to use a stethoscope to take a patient's blood pressure. You can imagine the internal horror now being felt as you and I dare to take control over heart disease and deny them the chance to put in four stents, three bypass grafts, then direct our future health habits.

But technology has a way of marching on. It will encounter resistance, bumps, and blind-alleys, but it will go on.

Dr. Jeffrey Dach on the Track Your Plaque program

Dr. Jeffrey Dach posted a great piece on his blog, Bioidentical Hormone Blog , about his perspective on the Track Your Plaque program.

It's worth reading even for those familiar with the program, just to see a slightly different perspective. He also included many great graphics to illustrate his points.

Vitamin D and programmed aging?

9. July 2008 William Davis (8)

As we age, we lose the capacity to activate vitamin D in the skin.

Studies suggest that, between ages 20 and 70, there is a 75% reduction in the ability to activate vitamin D. The capacity of conversion from 25 (OH) vitamin D to 1,25 di(OH) vitamin D also diminishes.

Holick M. Sunlight and vitamin D for bone health and prevention of autoimmune diseases, cancers, and cardiovascular disease.

From Holick, M. 2006

This would explain why 70-year olds come to the office, just back from the Caribbean sporting dark brown tans, are still deficient, often severely, in blood levels of vitamin D (25(OH) vitamin D). A tan does not equal vitamin D.

Courtesy Ipanemic

A practical way of looking at it is that anyone 40 years old or older has lost the majority of ability for vitamin D activation.

This often makes me wonder if the loss of vitamin D activating potential is nature's way to get rid of us. After all, after 40, we've pretty much had our opportunity to recreate and make our contribution to the species (at least in a primitive world in which humans evolved): we've exhausted our reproductive usefulness to the species.

Is the programmed decline of vitamin D skin activation a way to ensure that we develop diseases of senescence (aging)? The list of potential consequences of vitamin D deficiency includes: osteoporosis, poor balance and coordination, falls and fractures; cancer of the breast, bladder, colon, prostate, and blood; reductions in HDL, increases in triglycerides; increased inflammation (C-reactive protein, CRP); declining memory and mentation; coronary heart disease.

Isn't that also pretty much a list that describes aging?

A fascinating argument in support of this idea came from study from St Thomas’ Hospital and the London School of Medicine:

Higher serum vitamin D concentrations are associated with longer leukocyte telomere length in women

Telomeres are the "tails" of DNA that were formerly thought to be mistakes, just coding for nonsense. But more recent thinking has proposed that telomeres may provide a counting mechanism that shortens with aging and accelerates with stress and illness. This study suggests that both vitamin D and inflammation (CRP) impact telomere length: the lower the vitamin D, the shorter the telomere length, particularly when inflammation is greater.

Data supporting vitamin D's effects on preventing or treating cancer, osteoporosis, lipid abnormalities, inflammation, cardiovascular disease, etc., is developing rapidly.

Now the big question: If declining vitamin D is nature's way of ensuring our decline and death, does maintaining higher vitamin D also maintain youthfulness?

I don't have an answer, but it's a really intriguing idea.

Synthroid, Armour Thyroid, and the battle for T3

6. July 2008 William Davis (2)

In the last Heart Scan Blog post on thyroid issues, Is normal TSH too high?, the provocative findings of the the HUNT Study were discussed. The text of the study can be found at:

The association between TSH within the reference range and serum lipid concentrations in a population-based study. The HUNT Study

Hypothyroidism, or low thyroid that is signaled by high thyroid-stimulating hormone, TSH, is proving far more prevalent an issue than previously thought. While previous estimates put hypothyroidism as affecting only about 3% of younger populations, 10-20% of older populations (women more so), data like the HUNT Study suggest that, if lower and lower TSH levels (higher thyroid) are necessary for perfect heart health, then many more people stand to benefit than we used to think.

But another crucial issue in the world of hypothyroidism: Is T4 (thyroxine) enough? Or should we be supplementing T3 (triiodothyronine) along with T4?

Your friendly neighborhood primary care doctor or endocrinologist would likely argue vehemently that T4 (as Synthroid, Levoxyl, levothyroxine, and others) is adequate and not subject to the impurities and contaminants of natural thyroid extracts. They would also argue that T4 is effectively converted to T3 at the tissue level, and exogenous supplementation is unnecessary.

Others--most of all thyroid patients themselves, along with thyroid advocates like Mary Shomon and Janie Bowthorpe, along with some physicians--argue that supplementing T3 along with T4 can be very important. They argue that people feel better, have more physical energy, lose weight more effectively, and more completely resolve many of the phenomena of hypothryoidism with T3 added. There are also some data that argue the same.

Adding T3 to the mix may address the presumed poor conversion of T4 to T3 that is peculiar to some people. It may overcome the "reverse T3" phenomenon, the production of a useless look-alike T3 that occurs in some people. It may also (anecdotally) exert greater effects on some lipid/lipoprotein parameters, such as Lp(a).

My experiences adding T3 to T4 have been mixed: Some feel better, others do not. Some show objective improvements, others do not.

Nonetheless, hypothyroidism, or incompletely corrected hypothryoidism by way of inadequate T3, is an issue to consider in your plaque-control program.

More on this somewhat complex issue, along with practical solutions to consider, can be found on the Special Report to be released this week on the Track Your Plaque website.

Letter to New York Times

3. July 2008 William Davis (9)

All right. I sent a Letter to the Editor to the New York Times. No word from them; it's no longer news.

So here is what I tried to convey.

While the authors overall did a credible job of talking to my colleagues and laying out the issues, they made the crucial and boneheaded mistake of confusing CT heart scans with CT coronary angiograms. Sadly, many people who may have been considering having a simple screening heart scan may be scared away by the confused authors, Alexn Berenson and Reed Abelson.

They do correctly point out that, while CT coronary angiograms are fascinating examples of technology and a way of visualizing coronary arteries, this test all too often is being subverted into the "let's make money from high-tech testing" medical model. It's also a test that frequently leads to the "real" test, heart catheterization, since the "time bomb" you have in your arteries might "need" a stent.

CT coronary angiograms are also virtually useless for purposes of tracking disease, since they are not longitudinally (along the length of the artery) quantitative, nor should anyone be exposed to this much radiation repeatedly.

A simple heart scan, on the hand, provides a longitudinal summation of coronary plaque volume. Radiation exposure is sufficiently low that repeated scanning can be performed for purposes of tracking . . .yes, track your plaque.

Poorly-informed reporters can do a lot of damage. As always, you and I must dig a little deeper for the truth.

Dear Editor,

Re: Weighing the Costs of a CT Scan’s Look Inside the Heart

The Times featured an article on June 29th that discussed rapidly expanding use of CT scans for the heart:
Weighing the Costs of a CT Scan’s Look Inside the Heart.

The authors, Alex Berenson and Reed Abelson, stated that CT heart scans “expose patients to large doses of radiation, equivalent to at least several hundred X-rays, creating a small but real cancer risk.”

I’d like to offer a clarification.

Though the authors discuss both CT heart scans and CT coronary angiograms, they confuse the two and use the terms interchangeably.

A heart scan is a simple screening test for coronary atherosclerotic plaque. It detects the presence of calcium in the heart’s arteries, provided as a “score.” (Because calcium occupies 20% of total plaque volume, knowing the amount of calcium tells you how much total coronary plaque is present by applying this simple proportion.) Just having a high score should not prompt heart procedures, since people undergoing simple screening heart scans are without symptoms. However, a stress test may yield some useful information.

On present-day CT devices, heart scans expose a patient to 0.4 mSv of radiation on an electron-beam, or EBT, device, and on up to 1.2 mSv on a 64-slice multi-detector, or MDCT, device, compared to 0.1 mSv during a standard chest x-ray. CT heart scans are therefore performed with about the same quantity of radiation as a mammogram done to screen women for breast cancer, or about the equivalent of four chest x-rays on an EBT scanner, up to 12 chest-xrays on a MDCT scanner.

CT coronary angiograms, while performed on the same devices as heart scans, require x-ray dye to fill the contours of the coronary arteries. It also requires up to several hundred times more radiation. While new engineering innovations are being introduced that promise to reduce this exposure, the current devices being used today do indeed require a radiation dose equivalent to 100 to 400 chest x-rays (usually in the range of 10-15 mSv), a value that equals or exceeds that obtained during a conventional heart catheterization.

While heart scans are most useful to detect and quantify plaque that can help determine the intensity of a heart disease prevention program, CT coronary angiograms are generally used as prelude to hospital procedures like catheterizations, stents and bypass surgery. That’s because they are performed to look for (or rule out) “severe” blockages.
CT heart scans and CT coronary angiography are therefore two different tests that yield two different kinds of information, and yield two entirely different levels of radiation exposure.

This confusion from a major and respected media outlet like the New York Times is unfortunate, because it could persuade millions of people who otherwise could benefit from simple heart scans to avoid them because of misleading information on radiation exposure of a different test.

Thank you.

Red yeast rice alert

2. July 2008 William Davis (9)

While there have been some positive reports in the media lately about the cholesterol-reducing effects of red yeast rice, Consumer Lab has issued a very concerning report.

Because Consumer Lab is a subscription website (incidentally, the $20 per year membership fee is money well spent for insightful tests on many supplements, though new reports only come out a handful of times per year), I won't discuss the results of their red yeast rice in its entirety.

However, Consumer Lab testing uncovered several disturbing findings:

--The lovastatin content varied by a factor of 100, from 0.1 mg per tablet/capsule in one brand up to 10.6 mg in another brand. By FDA regulations, lovastatin is a drug and NO red yeast rice preparation is supposed to contain ANY lovastatin. Nonetheless, despite the marketing of supplement manufacturers, it is probably the lovastatin that is largely responsible for the LDL-reducing effect. The monacolins or mevinolins in red yeast rice add little, if any, further LDL-reducing effect.

--Several preparations contain a potential kidney toxin called citrinin. The Walgreen's product, specifically, contained substantial quantities of this toxin.

Interestingly, the FDA has taken repeated action against red yeast rice manufacturers and distributors because they continue to contain lovastatin. In the FDA's most recent action in August, 2007, for instance, Swanson's product and Sunburst Biorganics' Cholestrix, were both sent letters to stop selling their product because it contained lovastatin.

The Consumer Lab findings would explain the enormous variation in LDL-reducing effect of various red yeast rice products. In my experience, some work and reduce LDL 40 mg/dl or so, some fail to reduce LDL at all, others generate a modest effect, e.g., 5-10 mg/dl LDL reduction.

In effect, red yeast rice IS a statin drug, albeit a highly variable and weak one. Although readers of The Heart Scan Blog know that I am a big fan of nutritional supplements and self-empowerment in health, I am a bigger fan of truth. I despise B--- S---- of the sort that emits from some nutritional supplement manufacturers and drug companies.

I am puzzled by much of the public's readiness to embrace a statin drug if it comes from a supplement company while avoiding it if it comes from a drug manufacturer. Personally, I do not like the drug industry, their questionable (at best) ethics, their aggressive marketing tactics, their sleazy sales people.

But, in this instance, if a statin effect is desired, I'd reach for generic lovastatin before I purchased red yeast rice. The Consumer Lab report tells us that red yeast rice IS essentially a statin drug, an inconsistent one that often contains a potential toxin.

"Average amount of heart disease for age"

2. July 2008 William Davis (4)

A 72-year old woman came to my office after a complicated hospital stay (unrelated to heart disease). She'd undergone a CT coronary angiogram and heart scan as part of a pre-operative evaluation prior to a surgery for a non-heart related condition.

The heart scan portion of the test (I was impressed they even did this) yielded a heart scan score of 212. The CT coronary angiogram portion of the test revealed a 50% blockage in one artery, a lesser blockage in one other artery.

The cardiologist consulting on the case advised her that the amount of coronary disease detected was insufficient to pose risk during her surgical procedure. He also advised her that she had "an average amount of disease for age." He thought that nothing further was necessary since she was "average."

Say what?

What if I told you that you have an average amount of cancer for your age? After all, cancers become more common the older we get. Who would find that acceptable?

Then why should ANY amount of coronary atherosclerotic plaque be "acceptable for age"? Coronary plaque is a degenerative disease that poses risk for rupture. While it is indeed common, by no means should it be acceptable.

I would bet that this same cardiologist would be from the same school of thought that would be eager to advise heart catheterization, stent, and other procedures--revenue-generating procedures--should she have a heart attack appropriate for age.

I wish that I could tell you that this silly comment was provided by some peculiar, "everyone-knows-he's-crazy" doctor. But it was not. It was a solidly mainstream physician. He pooh-poohs nutrition, laughs when asked about nutritional supplements, thinks anyone complaining about symptoms less than a full-blown heart attack is a baby. He is respected by the primary care physicians, lectures on the advantages of prescription medications. In short, he is your typical conventional cardiologist.

This is the way they think. I know, because I was one of them. Thankfully, something banged me upside my head one day (my Mother's sudden cardiac death) and tipped me off to the painful irony of the conventional approach to heart disease.

There is NO amount of coronary disease appropriate for age. This notion is a remnant of the paternalistic, "I-know-better-than-you" attitude of the last century of medicine.

The 21st century promises a new age.

Quantum leaps

29. June 2008 William Davis (6)

A reader of The Heart Scan Blog and member of the Track Your Plaque program posted this comment on The Heart.org:

*The facts speak for themselves.*

Dr. William Davis and Dr. William Blanchet, your patients thank you for the low cost PREVENTIVE care you prescribe. The published facts speak for themselves. It is indeed a sad state of affairs, that the larger cardiology community does not take the time to research the data and results you have been reporting. Unfortunately it is the patients who are the victims of the mainstream, inappropriate, treatment protocols, as evidenced with the ongoing high rate of CV death rate.

I am dumbfounded by the lack of open-minded inquisitive curiosity to thoroughly research your claims by many/most cardiologists. Understood, we are all busy, but that is no excuse to stick with practices that do not result in major breakthrough improvements in patient outcomes.

Then again, we are all humans, and when "we" are convinced that "our" approach is correct, "we" tend to conveniently ignore any evidence to the contrary. "We" like to believe "we" have been right all along.

A very insightful book, recently published, says it all in its title: "Mistakes were made (but not by me)."

From the intensity of the comments on this topic, it is clear that we are in the middle of a battlefield. It is to be hoped that the facts will become visible before too much smoke obscures the field, and before the patients are all dead.

George Orwell said it correctly, back in 1946:

“We are all capable of believing things which we know to be untrue, and then, when we are finally proved wrong, imprudently twisting the facts so as to show that we were right. Intellectually, it is possible to carry on this process for an indefinite time: the only check on it is that sooner or later a false belief bumps up against solid reality usually on a battlefield.”

And, after several posts that preventive care with EBT would be too costly.....

*Heroic*

Prevention is what matters, but it is not very heroic. A hospital that advertises the highest volumes in heart bypasses and other heart "repair" procedures, sounds to many like a go-to place when one gets into trouble with one's heart.

Cardiologists who perform impressive surgical procedures are heroes. Not unlike fire-fighters. We celebrate them (deservedly!) for rescues and life saving heroic actions.

We tend to not pay much attention to the folks that work hard to minimize risk of calamities in the first place.

Similarly, we recently learned that it is too costly to build schools that are earthquake resistant in China. Parents had to look at their children's bodies, crushed.

Is it too graphic to imagine 20,000 American bodies, who died of heart disease, piled up on a field?

What will it take before we make prevention our first priority?

The reader also tells me that, prompted by his father's death from heart attack while following conventional advice after heart catheterization, he has lost 50 lbs and corrected his lipid patterns on the Track Your Plaque program. The reader is currently struggling with full correction of his severe small LDL pattern and is following some of the advice we discussed on our webinar recently.

Another Heart Scan Blog reader, Stan the Heretic, posted this quote from scientist, Max Planck, in his comment:

"A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it." - M. Planck

(Max Planck was a German physicist who developed quantum theory, a disruptive set of ideas that supplanted other explanations of energy mechanics of the day.)

I fear that may prove to be the case for heart disease. The revenue-generating formula for heart disease management that dominates practice in cardiovascular medicine today is so deeply ingrained into the thinking and revenue expectations of practicing cardiologists that a preventive or reversal approach just won't cut it--even if it is vastly superior.

That's why it is important for you to take control yourself. You will be the one who obtains and applies the information that saves your life or the lives of those around you. It is, in all likelihood, NOT your doctor who will save your life, but YOU.

Imagine the following headline:

War in Iraq a growing success: 20,000 Americans now dead!

If a newspaper ran that headline, we would all be outraged, and rightly so. Deaths in war are a tragedy. They are not something we celebrate.

Then why do we hear hospitals boasting about the number of bypass operations performed every year, number of heart catheterizations performed, number of heart attacks treated?

"_______ Hospital breaks 1000-heart bypass per year milestone"

"We treat more heart attacks than other other hospital in the state!"

"More people come to ________ Hospital than any other in the region!"

I hear this stuff on the radio, on TV, see it in newspapers and magazines, even on highway billboards every single day in Milwaukee.

Heart procedures, like deaths in war, are casualties of health.

They are not successes (though, of course, you can have a "successful" bypass). I see most procedures as a failure of prevention.

Death from heart attack is a failure of prevention. Tim Russert's death was a (unnecessary) failure of prevention. But so are bypass surgery, stents, and the like.

Such is the perverse state of affairs in hospitals and health: They celebrate illness. They glamorize it with ads displaying high-tech equipment, efficient staff in scrubs, "caring and friendly staff." But it is illness they are celebrating. Why? Because it has become a business necessity, a necessary strategy to remain competitive and profitable in the business called "healthcare" that makes money from treating people. The biggest return is from major procedures like bypass operations.

Every success in prevention denies the hospital an $80,000+ opportunity. You'll never hear that advertised.
