NY Times Jane Brody misses the mark



NY Times' health columnist, Jane Brody, recently wrote a bit of fluff for her paper:

"CT Scans of the Heart Come With Trade-Offs


In her report, she says:

Coronary CT scans are being sold directly to the public, and they have found a market in health-conscious people who can afford them. But screening exams can have downsides. They can cause needless worry, and they sometimes reveal other potential conditions that require invasive procedures like biopsies to diagnose.

I soon learned that among the strongest proponents of CT scans of coronary arteries were physicians with financial ties to drug companies that make statins and others connected to imaging centers that would profit directly from widespread CT screenings.



She then goes on to discuss how the Framingham scoring calculation can tell you whether or not you are at low-, intermediate-, or high-risk for heart disease. She therefore concludes that heart scans are therefore irrelevant for the majority of people. She then proceeds to take a statin agent.

This sort of nonsense continues to get published, despite the clear lack of real "digging" for the truth. She clearly fell for the conventional arguments that continue to mis-guide the majority of people, myths like:

--the Framingham scoring system is reliable--Reliable it is NOT; it is susceptible to substantial "misclassification" bias, meaning people who appear low risk can actually be high risk, and people at high risk can actually be low risk. Among the latest studies that question the scoring system is Family history of premature coronary heart disease and coronary artery calcification: Multi-Ethnic Study of Atherosclerosis (MESA). This study pointed out how the Framingham scoring system, which leaves out family history, can cause people classified as low risk to actually have substantial heart scan scores. This is crucial. A heart scan gets beyond the uncertainties and shows with >95% certainty whether or not hidden coronary atherosclerotic plaque is present.

--"Coronary risk" is a dynammic phenomenon, subject to changes in a person's life. What if, for instance, a person smoked for 20 years, quit 10 years ago, lost 30 lbs, dropped their blood pressure as a result of the weight loss, then relied on the Framingham Risk Calculator to determine risk. They would likely be classified as low- risk, since risk factors now appear favorable. This person could easily have a heart scan score of 500, or 700, or 1000, levels that carry a cardiovascular event risk of 5-25% per year, hardly low-risk, because much of their risk accumulated earlier in life and is no longer revealed by an assessment of risk factors.

--There are sources of risk that have nothing to do with Framingham, such as lipoprotein(a), which is often revealed by family history; the presence of small LDL, which co-varies with HDL and triglycerides, but can behave independently also; and, my favorite, deficiency of vitamin D. This would explain part of the 60-70% of people who are typically mis-classified by Framingham.


Where did Ms. Brody get the idea that proponents of heart scans had ties to drug companies? I think she's barking up the wrong tree on that one. Of course, she ends up on a statin drug. For my part, I am a critic of statin drugs. Yes, they play a role, but they are miserably misused and abused by practicing physicians, based on the endless onslaught of drug company-sponsored trials that have served to distort their usefulness.

If I were Ms. Brody, I would be quaking in my shoes, not knowing what my true risk for heart disease was, relying on the--at best--30% reduction in heart attack risk of Lipitor or other statin drug. Ms. Brody: You are not cured, you're simply wearing a superficial Band-Aid. If you want to know your true risk for heart attack, and you want a precise value that you can track over time, the answer is simple: Reject the conventional notion and get a heart scan.

"There must be a mistake"

Neal is our current male record holder for greatest reduction in heart scan score. (Yes, the ladies have the lead!)

You may remember that this 40-year old man reduced his heart scan score from 339 to 161--a 51% drop. If you haven't yet read his story, go to

http://www.cureality.com/library/fl_07-001nealt51.asp


Neal reminded me of the experience he had when he underwent his second heart scan. Both scans had been performed at the same scanning center. At this center, the radiologists provide the added service of sitting down with people and actually going over the images and results.

After the scan, the radiologist pulled up the result from Neal's first scan for comparison. "There must be a mistake! This score is lower. Scores never drop."

The radiologist was apparently stumped, unable to provide an explanation. However, Neal then proceeded to tell the radiologist that we had warned Neal that this could happen and that he might even be told that it was due to error of some sort. This yielded a puzzled look on the radiologist but no further comment.

Of course it's not a mistake. It's something we achieve on purpose. Curiously, I still get comments that this is impossible, heart scan scores never drop, etc. Of course, those of you following this conversation know this is completely untrue. Heart scan scores DO drop, and sometimes drop enormous amounts, as it did for Neal.

I would have liked the radiologist to have had the lightbulb of understanding go off in his head when he realized that a reduction in heart scan score is a cause for celebration. Unfortunately, this radiologist's reaction is all too common: disbelief, confusion, dismissal.

Heart disease reversal is simply not in the realm of understanding of most doctors, radiologists and cardiologists alike. By conventional thought, if you have it, it just gets worse. "Maybe some high-dose Lipitor might help."

Ironically, when they see it right in front of their eyes, plain as day on the computer screen, they don't understand what has happened. It's Greek to them.

Should this happen to you, don't be surprised. Just bite your tongue, because you know better.

Jimmy Moore Interview: Is saturated fat the villain we thought?

Enter "weight loss" or "low carb" in your web search and you can't help but stumble across the prolific and widely-connected Jimmy Moore.

On his Blog, Livin' la Vida Lo Carb , Jimmy conducts a wide-ranging and informative discussion of the benefits of a low carbohydrate diet, a la Atkins. Though his initial claim to fame was the 180 lbs he lost in his first year of dieting on this approach, Jimmy has extended the conversation and built a considerable community of like-minded individuals, all of whom are participating in this grand "experiment."

Anybody who looks at lipoproteins and associated factors in health will quickly come to the conclusion that processed carbohydrates are the culprits in much of heart disease, diabetes, and heart disease. But I have had a hard time dismissing the ill-effects of saturated fat. After all, we've all been taught--drilled--with the idea that saturated fats cause LDL cholesterol to go higher, cause arterial constriction, growth of atherosclerotic plaque, inflammation, even cancer.

But there does indeed seem to be a growing sentinment that this long-held dogma may not be true. So I went to the ever-entertaining and informative Jimmy Moore, an able spokesman for these concepts.




TYP: It's certainly impossible to argue with the success you had in weight loss and the health you've regained on your program.

I think that the approach we use in diet in the Track Your Plaque program and the nutrition approach you advocate overlap to a great extent. We both emphasize plenty of vegetables, fruits, healthy oils, nuts, etc. The major point of difference seems to lie in saturated fat: We say restrict it, you say don't restrict it. Could you elaborate?





JM: Thank you for inviting me to your blog today, Dr. Davis. I have nothing but deep respect and admiration for the work you are doing to help educate others about how to keep their heart health in tip-top shape. Keep fighting the good fight, my friend.

While we do agree on probably 99% of the basic tenets of what I describe as
"livin' la vida low-carb," the issue of saturated fat to me is one where we
indeed do not. It's not a deal breaker regarding my support for what you do
just as I'm sure you would say the same regarding your backing of what I do. If
we all agreed on everything, then what a boring world this would be!

My thinking on saturated fat has evolved since I started eating this way nearly
four years ago. Like most people, I was terrified to eat ANY fat at all because
of the abject fear that people like Dr. Dean Ornish and other so-called health
"experts" instilled in me about how dangerously unhealthy it is to consume it.
This fat phobia is arguably the single biggest contributor to the ongoing
obesity crisis our world faces today.

With that said, you and I both know fat consumption is a part of a healthy
lifestyle. There are just too many benefits to the body that come from the
consumption of fats and even saturated fats such as coconut oil, butter, lard,
nuts, seeds, and animal fat when it is combined with a restricted carbohydrate
intake.

An intriguing study was presented at a scientific conference in November 2006 by two highly-respected researchers--Dr. Stephen Phinney from the University of California at Davis and Dr. Jeff Volek from the University of Connecticut--who conducted a side-by-side comparison of the amount of saturated fat in the blood of people on a low-carb diet with those following those highly-touted low-fat diets. What they found was the low-carb study participants had "significantly less" saturated fat in their blood than the low-fatties did.

Here are the actual numbers from the study:

- LOW-FAT/HIGH-CARB DIETERS: lowered saturated fat by 24%
- LOW-CARB/HIGH-FAT DIETERS: lowered saturated fat by 57%
- Eating 3X the saturated fat cut the amount in the blood in half

In an interview I conducted at my blog with Dr. Volek last year (here's the
link: http://livinlavidalocarb.blogspot.com/2006/09/volek-high-carb-low-fat-diet-useless-to.html),
he said the conventional wisdom regarding fat, especially saturate fat, is dead
wrong while the significance of carbs is all but ignored by those who claim to
understand the metabolic response mechanism.

Here's what Dr. Volek said in my interview:

"Eating fat does not make you fat, storing fat makes you fat. And carbohydrates play a major role in storing fat. So the level of dietary carbohydrate is really the most important factor to control because it dictates what happens to fat. Carbs are dominant and fat is passive. When carbohydrates are low, fat tends to be burned, and when carbohydrates are high dietary fat tends to be stored. The same holds true for the atherogenic effects of saturated fat. The body handles saturated fat better when carbohydrates are low."

Long-time low-carb practitioner and current President of the American Society of Bariatric Physicians (ASBP) Dr. Mary C. Vernon from Lawrence, Kansas confirms the findings of Dr. Volek and Dr. Phinney in a succinct recap of what their research showed.

Here's what she said:

"Eating fat (whatever kind) does not make you fat. It does not increase blood
stream saturated fat. Eating carbs does make you fat. Eating carbs does put
saturated fat in your blood stream."

To me, as a simple layperson with no medical background, it's all a matter of who you believe. Do we continue to buy into the low-fat propaganda machine and assume that what they are telling us about saturated fat is true? Or do we instead start paying closer attention to the latest research that is coming out about saturated fat that doesn't exactly line up with the edicts of the last three decades? The choice for me is a simple one.

And if you haven't read the brand new Gary Taubes book entitled GOOD CALORIES, BAD CALORIES yet, then it is REQUIRED reading to arm yourself with the research studies about fat. After you read that book, it will be almost impossible for ANYONE to believe fat, including saturated fat, is unhealthy.



TYP: In our program, we advocate a wheat-free approach for many people, because of the addictive potential of wheat products, as well as the flagrant creation of the small LDL pattern that wheat products create, thereby adding to atherosclerotic plaque growth. However, many people express a concern over a lack of fiber in their diets if they eliminate whole wheat bread, pasta, Fiber One, Raisin Bran cereal, etc.

Have you encountered any phenomena of low-fiber on your approach?

JM: What an excellent question and I even wrote a humorous blog post about the importance of fiber intake called "Allow Your Bowel To Shake, Rattle, And Roll" (http://livinlavidalocarb.blogspot.com/2006/06/allow-your-bowel-to-shake-rattle-and.html).

Fiber consumption is another one of those issues that not everyone who advocates
a controlled-carb approach agrees is necessary. I'm on the side that it IS a healthy part of your diet and should be consumed in high enough quantities to keep you regular...something many people think is impossible on a low-carb diet.
Not true! I take a fiber supplement like FiberCon, eat plenty of high-fiber vegetables, drink lots of water, and even consume high-fiber, low-carb products that help me maintain high levels of fiber in my diet (see my favorite ones in this post: http://livinlavidalocarb.blogspot.com/2007/04/there-are-plenty-of-low-carb-fiber.html).

As for consuming the highly-touted "healthy whole grain" cereals that you
mentioned, what a travesty that would be for people trying to manage their
weight and health. While the cereal manufacturers have had a heyday in their
marketing efforts promoting their whole grain content, it's all just a big fat
ruse on the public trying to convince them that these cereals are somehow healthy for their bodies. Sure, they're better than the sugary cereals, but all those grains are metabolized as sugar inside the body, so you might as well be eating Lucky Charms and Fruit Loops!

Many of these "healthy" cereals contain as many carbohydrates in a single bowl
without the milk as I would eat in an entire day. Raisin Bran, for example, which used to be my favorite cereal before my low-carb lifestye, has a whopping 47 grams of carbohydrates. Needless to say, I don't touch that with a ten-foot pole nowadays because I would surely gain weight and get back on the blood sugar rollercoaster ride that I was on prior to beginning the Atkins diet on January 1, 2004. Plus, all those carbs just make you hungrier sooner, so it's better just to eat some delicious eggs cooked in butter, a couple of slices of sausage, and tomato slices to start your day off right. You'll get enough fiber in your body the rest of your day.



TYP: 180 lbs of weight loss in your first year is absolutely astounding.

I take it that you've continued this trend and have lost more weight since your early success. What role did exercise play during your first year and subsequently?
How are your food choices today different from that first year?

JM: Yes, that weight loss was indeed one of the greatest accomplishments I have ever experienced in my life. It was a hard-fought battle that even included a 10-week period where I was stalled with no weight loss. But I knew my chosen diet was the right one for me because I felt better than I ever had on a diet, was never hungry because I ate every 2-3 hours, and could see myself doing this for the rest of my life. So far, so good!

It has been close to four years since I began this journey and I am indeed continuing this pathway to better health. My low weight in 2004 was 230 pounds and I currently weigh 225 pounds. As long as I keep my carbs reduced, I am able to maintain my weight right where it is. I've had minor fluctuations in both directions where I got down to as low as 215 pounds at one point (but didn't feel good at that weight) and as high as 252 pounds (when I was allowing myself one too many high-carb foods here and there).

There's a balance that people need to find for themselves and it's different for
all of us. I am one of the unlucky people who has to keep his carbohydrate
intake below 50g daily or I gain. It's just a fact of life that I've come to
grips with and realize is a necessity in order to manage my weight for the rest
of my life. But I wouldn't have it any other way!

Exercise was indeed a part of my low-carb weight loss success in 2004 as I
forced myself to do cardio every single day as a commitment to this journey. In
hindsight, that was probably not the best thing for me to do since the body has
a rather peculiar way of telling you it needs to wiggle and move spontaneously
on its own rather than forcing the issue. But I consider the exercise I did to
be such an integral part of my success that I dedicated an entire chapter of my
book to the subject.

Today, my daily cardio routine is out the window and I choose instead to engage
in activities outside the gym that let me burn calories and have some fun in the
process. I regularly play volleyball, basketball, and referee flag football at
my church which all give me quite a workout. I'm very physically active and fit
on my 6'3" body and just enjoy burning off all this excess energy that I have
been given since losing nearly have my weight! I do want to get into a little
more organized resistance training routine soon to try to shape and tone some
areas of my body that still show signs of that 410-pound man I used to be
(although the loose, hanging skin in my abdomen and inner thighs isn't going to
get any better with exercise since the elasticity has been ruined from being
stretched out so far). Here is a link to some posts and pictures I have written
about this subject:
http://lowcarblinks.blogspot.com/2007/04/theme-based-low-carb-links-loose-skin.html

As for my food choices today compared to my weight loss year in 2004, they
haven't really changed a whole lot. This was a lifestyle change in every sense
of the phrase and I've learned to implement this way of eating into a permanent
and healthy diet that I can and will gladly live with forever and ever amen. I
probably eat more berries, melons, and nuts today than I did then, but otherwise
it's the identical diet.



TYP: I'm sure that you are as impressed as I am that much of the wisdom in healthy eating doesn't always come from doctors or clinical studies, but from the collective wisdom that emerges from this national experiment (inadvertent, for the most part) in eating. Your Livin' La Vida Low-Carb is, in my view, a perfect example of the sort of wisdom that is helping all of us understand what happened to our health over the last 20 years.

Does the approach you advocate today differ in any substantial way from the diet as originally articulated by Dr. Atkins?

JM: Actually, my personal diet is precisely based on the teaching of the late great Dr. Robert C. Atkins in his classic bestseller DR. ATKINS' NEW DIET REVOLUTION (DANDR) book. But most people are surprised when they learn I do not necessarily advocate the Atkins diet as the nutritional approach for everyone.

Nope, I sure don't!

Instead, my philosophy is simple: Find the diet plan that will work for YOU, read and research everything you can about that chosen plan, follow that plan exactly as prescribed by the author of that book, and then KEEP doing that plan for the rest of your life. If you do that, then there's no reason why you can't succeed just like I did.

Anyone interested in doing the low-carb lifestyle and needs help finding which
plan is right for them, let me HIGHLY encourage you to pick up a copy of Dr. Jonny Bowden's LIVING THE LOW-CARB LIFE (read my review: http://livinlavidalocarb.blogspot.com/2005/05/must-have-book-for-everybody-doing-low.html).
It's the perfect overview of low-carb living with a comparison and recap of the
major plans.

THANK YOU again for allowing me to share my story with you and your readers, Dr.
Davis!

TYP: And thanks to you, Jimmy!

Mammogram of the heart

Some people have called CT heart scans the "mammogram of the heart." The analogy contains a lot of wisdom.

First of all, both--mammograms and CT heart scans--are screening tests, one for cancer, of course, the other for coronary atherosclerotic plaque. Both are performed in specific age groups, mammograms in women 40 years and over (generally), heart scans in women 50 years and over (generally).


















Mammograms: Left, normal; right, a small mass. (Courtesy Nat'l Institutes of Health and Wikipedia.)



Both are also meant to be repeated periodically when normal as a surveillance process.

Both use low quantities of radiation of about 0.3-0.4 mSv (the most real-life measure of total body exposure), a modest quantity of radiation.

Both are good for their purposes, though not perfect. Can a mammogram performed properly miss a small cancerous mass? Sure it can, but it's still unusual. Can a CT heart scan miss the non-calcified plaque prone to rupture? Sure it can, but this is also unlikely (<5% probability).

Given the exorbitant costs of medical tests, both are quite inexpensive. On the flip side, they are both also quite unprofitable for the centers providing the tests. Unfortunately, this means that mammography centers and heart scan centers come and go because of the difficulties of the profit-side of these services.

Both tests initially struggled to gain acceptance among the medical community. In 1960, for instance, mammograms were performed on standard x-ray devices, the same as that used to perform chest x-rays--low precision, high radiation back then. In 1969, dedicated mammography devices made the scene. However, it took over 10 years for even these new dedicated devices to become widely used. Use of mammograms has gradually increased over the ensuing 20 years. In other words, 47 years have passed since the introduction of mammography.

CT heart scans, of course, have had a shorter history of approximately 20 years, since engineer, Dr. Douglas Boyd, first invented the "ultra-fast" EBT devices, the first devices with sufficient scanning speed to scan the heart and coronary arteries.

One interesting difference between the two: In a woman between the age of 50 and 60, the likelihood of detecting cancer is 1 in 237. The likelihood of detecting coronary atherosclerotic plaque? About 1 in 4. Coronary disease eventually kills 1 in 3 females, hugely overshadowing breast cancer in frequency.


Progress on both fronts, one in cancer detection, the other in atherosclerotic coronary plaque detection. But still lots more progress to go.

Dr. Susie Rockway on conjugated linoleic acid (CLA)

I’m fascinated by the perspectives that nutritionists (free-thinking ones, at least), food scientists, and biochemists bring on nutrition and nutritional supplements.

A few months ago, I met a fascinating nutritionist/biochemist named Susie Rockway, PhD. Dr. Rockway brings a world of experience in the world of nutritional supplements, clinical trials with supplements, and their development. She has special expertise in conjugated linoleic acid (CLA), having been among the scientists who initially developed CLA as a supplement. We are also exploring CLA as a possible addition to the Track Your Plaque program and wanted to get Dr. Rockway’s perspectives.

So I asked Dr. Rockway if she’d answer a few questions for us.






TYP: Dr. Rockway, we understand that you are particularly excited about the prospects of CLA for FAT loss and perhaps for regression of atherosclerosis. Can you tell us about the origins of your interest in CLA and why you're so enthusiastic?

Dr. Rockway: I have been fascinated with this unique fatty acid since the early 1990’s when CLA was first being discussed as nature’s most potent anti-carcinogen. I was then working in the granting/funding section of the National Dairy Council and saw this molecule as truly one of the future functional fats that would likely benefit people (next to omega-3’s!)

I think the benefits of CLA have just begun to be investigated—animal studies are extraordinary for showing fat reduction, lean mass (muscle) increases, immune enhancements, blood glucose normalization, anti-inflammatory properties and plaque reduction!

Human data to date is very encouraging for fat reduction. As a nutritionist seeing the massive increase in abdominal fat (stomach fat) in the world population and the direct relationship to cardiovascular disease, I see CLA as a great supplement to take to help this. Of course eating lots of vegetables, fruit, lean protein and whole grain products is also a must for maximizing good health.

I am studying the impact of CLA in reducing muscle loss in aging women—a condition known as sarcopenia. As we lose muscle with age, we lose strength, falls increase, we become frailer, and eventually many of us lose our independence. Along with the muscle atrophy, most people gain fat—never a good thing! So, if CLA can reduce fat and increase muscle, our bodies are more likely to withstand the hurdles that life throws at us much more efficiently.

So, how can you not be excited about this very bioactive molecule?




TYP: What are your specific areas of interest in nutrition and health?

Dr. Rockway: I strive to understand the role of bioactive molecules that can be taken to improve the aging process and enhance health.

As a trained nutritional biochemist, we tend to look at cell metabolism in a very ideal sense: what we learned in our biochemistry texts years ago where all substrates, proteins, enzymes, etc. are made exactly when we need them, where all cells behave as they should.

Unfortunately, little research has been devoted to understanding the changes in metabolism as we age. Do we still produce everything as efficiently as when we were 20? I suspect not. So, I think we need a little help, and supplements are a key to getting there.

Two nutrients that I think are emerging as “super nutrients” are the fatty acids found in fish oil (EPA and DHA) and vitamin D. Where we know these two nutrients are essential for life, we are seeing that they play a huge role in the QUALITY of life. Mood, depression, PMS, wound healing, bone growth, atherosclerosis, and arthritis are clinical areas where we see a direct benefit with doses of omega-3 and Vitamin D that are probably much greater than the RDA. Our current requirements for nutrients are really based on fixing deficiencies and not maximizing health, and maximizing health is where I’m at.

Thus, I am very interested molecules like CLA as mentioned above, and other bioactive ingredients such as plant derived ingredients (phytochemicals) called flavonoids that may well help explain why people who have diets high in fruits and vegetables are less likely to have certain cancers and heart disease. Reducing oxidative stress through foods that provide these active molecules (think colored fruits and veggies) is a new and exciting area of research.



TYP:The big "diet experiment" in America has clearly steered people in the wrong direction, usually by 50 or more pounds. As a scientist in nutrition, what are your thoughts?

Dr. Rockway: The American Heart Association was keen 20 years ago to promote the low-fat diet for all Americans as the key way to reduce cholesterol levels and decrease chance of heart disease, the number one killer of men and women. However, I must admit the nutritional community bought into this one, too. Unfortunately, the general public took this message to reduce percent fat in their diet (and they did a bit), but increased overall calories instead—and a large portion of the increased calories was from simple carbohydrates. I’m convinced that this in itself has been part of the huge rise in obesity…we simply eat more food and it’s not the healthy kind of food either.

When you increase sugar intake beyond what you burn off, you will store some of it as glycogen in the liver and muscles, but you will convert most of the excess into fat—and that we can store very efficiently! The fat that is made in the liver is sent to the blood as VLDL’s which are the precursor to the class of lipids called low density lipoproteins (LDL) that are the “lethal” type of cholesterol circulating in our blood.

So, Americans now have to listen to a new message that they need to eat more fruits and vegetables in hopes they will cut down on fast foods—tending to be high in fat (saturated particularly), low in fiber and low in nutrients and other high calorie dense foods. We nutritionists have our work cut out for us, that’s for sure.



TYP: We are especially excited that nutritionists are assuming a leading role in shining light on the confusion in diet and nutrition that has characterized the last 40 years. Do you have a sense for the emerging important issues for the next 10 years?

Dr. Rockway: Certainly, the scientists in the nutritional field are well aware of the problems facing this nation—it’s in fixing them that we fall short!

We aren’t very well coordinated to get a single message out, nor do we all agree on what that message should be. I feel that people need to eat healthy MOST OF THE TIME, exercise all of the time, and take supplements that have clear evidence of benefit. Lots of my colleagues would not concur with supplement use. Our bodies were designed to move a lot and eat a lot…we just do the latter now and are paying the price!

One emerging and very exciting area that we have to teach Americans is that all fat is not bad. The different types of fat—omega-6 vs. omega-3, are where we need to focus our education.

Decreasing the corn oil we pour on everything needs to go out the window! Consume olive oil and eat fish or take fish oil supplements—we simply have tons and tons of research showing the benefits of reducing the ratio of omega-6 to omega-3. Did you know that cattle that are grass fed actually have less omega-6 in their tissues and more CLA? But most cattle are fed corn-based diets, so we have perturbed their natural selection of food and their fat composition.

See, it all comes back to CLA!


TYP: Thanks, Susie!

Which is better?

If you have the common pattern of high LDL particle number (NMR) with small LDL--a pattern highly related to coronary plaque--which is better:




Lipitor or a combination of fish oil, vitamin D, and elimination of wheat?


Lipitor quite effectively reduces LDL particle number, usually on the order of 40% or so. Effect on LDL particle size: None. Side-effects: plenty, including muscle aches (inevitable in my experience, not the ridiculous 2% they claim) and occasionally mental effects such as impaired short-term memory.

Lipitor does seem to exert a modest effect on reduction of C-reactive protein, around 30%. It also reduces cardiovascular events by 30%.



A combination of fish oil, vitamin D, and elimination of wheat:

Reduces LDL particle number commonly by a similar 40% (though variable, depending on body weight). There is substantial improvement in LDL particle size, a large drop in C-reactive protein, often >50%, a 30% or more reduction in cardiovacular events.



On this combination, however, you also:

--Lose weight, often substantially.

--Improve bone health, esp. osteoporosis and arthritis.

--Reduce cancer risk from the vit D supplementation.

--Reduce risk of stroke.

--Reduce postprandial (after-eating) abnormalities like intermediate-density lipoprotein.

--Reduce winter blues.

--Experience more energy.

--Obtain increased clarity of thought (from elimination of wheat).

--Reduce blood pressure.


Oh, and there's no muscle aches.

Heart health for stupid people

I'm kidding.

What I'm referring to is the incredibly lame information I come across that passes as "heart health" on the internet, magazines, and other media. Just to keep abreast of what is being said, I subscribe to multiple newsletters and magazines and I witness the sorts of advice offered to the reading public.

A recent long-winded article on a popular website listed the "exciting" strategies available for a healthy heart:

Eat healthy--by eating a "balanced" diet low in saturated fat

Don't smoke

Exercise

Don't ignore chest pain symptoms or breathlessness

Know your numbers! meaning your cholesterol numbers. "If your cholesterol is high, you may need to speak to your doctor about medication to reduce it."


Surely they must all believe we're stupid. Otherwise, why would they repeat the same obvious information over and over again? Quit smoking? Gee, you think so?

How about some real heart healthy advice:

Get a heart scan--since we have to accept that cholesterol values are a miserable failure in detecting hidden heart disease. So is waiting for symptoms to appear.

If you have any measure of coronary plaque, ask your doctor to assess lipoproteins, not lipids (cholesterol).

Take fish oil for omega-3 fatty acids--At a dose of 1000 mg or more of EPA + DHA, heart attack risk is reduced by at least 28%.

Eliminate wheat and other processed carbohydrates --Small LDL has emerged as the number one cause of coronary plaque, not high cholesterol from saturated fat.

Get vitamin D assessed--The effects are huge--HUGE. There's already a study in a kidney disease population that showed a substantial reduction in mortality with vitamin D supplementation. More data are coming, including our own.


That's a start--truly effective, practical heart healthy strategies that go way beyond the conventional bland advice.

Money, money, money, money

I've been asked the question numerous times:

Why aren't heart scans more popular?

First, let me qualify by saying that heart scan have indeed grown in popularity over the past decade. I think the real question is:

Given the enormous usefulness of CT heart scanning to detect hidden, asymptomatic coronary atherosclerotic plaque, why haven't they more readily been incorporated into conventional medical practice?

That's easy: There's no money in it.


Say, for instance, your doctor orders a heart scan and somehow receives a $1000 for the test. Scan centers would be scanning 100 people a day, falling over themselves to do scans.

This would be similar to a heart catheterization. Order a catheterization, do 30 minutes of work, and get $1000. Or, order a nuclear stress test. Depending on how its done and where, $1800-4000 is paid by the insurer.

Order a CT heart scan and how much is paid to the doctor? Usually nothing. At most, a nominal fee might be paid if the doctor reads the scan.

With heart scans, there simply is no big payoff.

We learned the implications of this situation 10 years ago when I was trying to help my friend, Steve Burlingame, the owner of Milwaukee Heart Scan. (I am NOT and NEVER WAS an owner.) Steve was trying to let everybody know about this great new $2 million dollar heart scan device in the Milwaukee area.

The first few years were tough for Steve: Carrying the substantial expense of this device while doctors essentially gave the technology the cold shoulder. It simply did not fit into the financial equation. Why change the way things were, particularly when there was virtually no financial reason to do so? To counter this, Milwaukee Heart Scan followed the model many other scan centers have followed and marketed directly to the public.

I see this as yet another example of why people need to take control of health care away from doctors and hospitals, the current controllers of the system who are providing a disservice to the public they are supposed to be serving. These institutions, for the most part, serve their self-serving financial interests, not your health interests. It's the same equation that drives food manufacturers to make more and more processed carbohydrate foods that they sell for substantial markups, not green peppers and cucumbers that make little money.

I regard heart scans as among the greatest self-empowering tools in health ever conceived. It was that way in 1997; it remains that way in 2007.

The many faces of LDL

Ginnie came in for an opinion about her heart scan score of 393. At age 57, this put her in the 99th percentile, a high score.

As usual, we did a lipoprotein analysis by NMR (Liposcience). Some numbers:

LDL cholesterol: 96 mg/dl
This value puts Ginnie's LDL in the most favorable 25% in the country.


LDL particle number: 2140 nmol/l
This value is in the worst 25% of the country and is the equivalent of an LDL cholesterol of 214 mg/dl (take off the zero).

In addition, over 90% of Ginnie's LDL particles fell into the small class.

Had we run some other values, how would they have turned out? These are my estimates (since we didn't actually run them in Ginnie), but having run side-by-side numbers in past, reasonable estimates would have put:

Apoprotein B somewhere in the 120 to 140 mg/dl range

Direct LDL 100-130 mg/dl range.


In other words, conventional calculated LDL is the least reliable of all the ways of examining low-density lipoprotein.

It can also go the other way: High calculated LDL, low LDL particle number or ApoB or direct LDL. And, indeed, these other measures have proven superior in their ability to predict "events" like heart attack over conventional calculated LDL.

Unfortunately, relying on conventional LDL is like a broken speedometer on your car. You really can't gauge accurately how fast you're going; sometimes you could be way off. While insurance companies and many physicians still continue to balk at this argument, the data have already been generated that show that lipoprotein analysis (my bias is NMR) is not just superior, but enormously superior for accuracy and event prediction.

In addition, lipoprotein analysis has proven a crucial tool that accounts for our extraordinary success in reducing and controlling CT heart scan scores in the Track Your Plaque program. I doubt that we could have achieved the same level of success using conventional lipids.

I'm also aware of the logistical difficulties obtaining lipoprotein testing in a world enthusiastically supportive of hospital procedures and smugly ignorant of superior prevention tools like lipoprotein analysis. I've learned just how difficult it can be in our Track Your Plaque Member Forum; I've also learned about some strategies for obtaining these tests that I hadn't been aware of, thanks to the resourcefulness of our Members.

We will be working on some solutions in the coming months.

What does "Success" mean in the Track Your Plaque program?

Say you begin with a CT heart scan score of 400.

You correct your lipoprotein pattterns, take fish oil, correct 25-OH-vitamin D3 to 50 ng/ml, correct your other hidden patterns, follow a diet suited to your patterns.

One year later, you get another heart scan. What score would constitute "success"?

With all of our recent talk about record-setting reductions in heart scan scores, is it really necessary to drop your score that much to succeed?

For instance, is our latest record-setting 63% drop in score better than "only" a 10% drop in score? Both represent reversal of coronary plaque. Both signify huge reductions in risk for plaque rupture, or heart attack.

You can read about how we view the various forms of success in the program by reading our latest Track Your Plaque Special Report, Winning Your Personal War with Heart Disease: The Track Your Plaque 5 Stages of Success.

We are making the Report available to everyone. Just go to the www.cureality.com homepage.
More on aortic valve disease and vitamin D

More on aortic valve disease and vitamin D

I hope I'm not getting my hopes up prematurely, but I believe that I've seen it once again: Dramatic reversal of aortic valve disease.

This 64-year old man came to me because of a heart scan score of 212. Jack proved to have small LDL, lipoprotein(a), and pre-diabetes. But there was a wrench in the works: Because of a new murmur, we obtain an echocardiogram that revealed a mildly stiff ("stenotic") aortic valve, one of the heart valves within the heart that can develop abnormal stiffness with time.

You can think of aortic valve disease as something like arthritis--a phenomenon of "wear and tear" that progresses over time, but doesn't just go away. In fact, the usual history is that, once detected, we expect it to get worse over the next few years. The stiff aortic valve eventually causes symptoms like chest pains, breathlessness, lightheadedness, and in very severe cases, passing out. For this reason, when symptoms appear, most cardiologists recommend surgical aortic valve replacement with a mechanical or a bio-prosthetic ("pig") valve.

Now, Jack's first aortic valve area (the parameter we follow by echocardiogram representing the effective area of the valve opening when viewed end on) was 1.6 cm2. A year later: 1.4 cm2. One year later again: 1.1 cm2.

In other words, progressive deterioration and a shrinking valve area. Most people begin to develop symptoms when they drop below 1.0 cm2.

Resigned to a new valve sometime in the next year or two, Jack underwent yet another echocardiogram: Valve area 1.8 cm2.

Is this for real? I had Jack come into the office. Lo and behold, to my shock and amazement, the prominent heart murmur he had all along was now barely audible.

I'm quite excited. However, it remains too early to get carried away. I've now seen this in a handful of people, all with aortic valve disease.

Aortic valve stenosis is generally regarded as a progressive disease that must eventually be corrected with surgery--period. The only other strategy that has proven to be of any benefit is Crestor 40 mg per day, an intolerable dose in my experience.

If the vitamin D effect on aortic valve disease proves consistent in future, even in a percentage of people, then hallelujah! We will be tracking this experience in future.

    What does vitamin D have to do with the improved heart valve?

    Maybe a little vitamin k with the vitamin d would give even better results for aortic valve disease.

  • Dr. Davis

    8/22/2007 9:46:00 PM |

    If this is true, I can only speculate on the mechanism for vitamin D's effect. It might include anti-inflammatory effects, suppression or modification of calcium deposition, and lipid (cholesterol) effects. However, this is just my speculation.

    I also agree that adding vitamin K2 may exert an effect, particularly in view of the valve disease that develops when people take the vitamin K blocker, Coumadin.

    Why do you stress Vitamin D3 supplements be in gel cap form?  Many of these contain Vitamin A in addition to the D.  If capsules of D are taken after a meal containing some fat, woulden't that suffce?

  • Dr. Davis

    8/31/2007 3:25:00 PM |

    If you want consistent absorption of vitamin D, gelcaps are best. Tablets are, in my view, next to worthless because of the erratic absorption, even when taken with a fatty meal.

    You can find D without A. Go to Vitamin Shoppe or buy Carlsons'brand.

    Yes. It was vitamin D supplementation that I presume was the factor behind the effect on valve disease.

    Any suggestions on dosage requirements of D3 gel caps?

  • Dr. Davis

    10/2/2007 6:22:00 PM |

    We've used anywhere from 4000-8000 units per day of an oil-based gelcap to achieve this effect.

    I'm 60 and just this week was diagnosed by echo as having a bicuspid aortic valve that is clacified, sclerosed and fused with a valve area of 1.1cm.  I'm asymptomatic, but my reading shows I'm headed for valve replacement within a few years at most.  I read you anecdotal reports of vitmain D apparent reversal of aortic stenosis.  However, I am aware that vitamin D can increase calcium deposition in tissues.  Are you sure this is safe for patients like me?  You are aware that nothing to date has been proven to change the natural history of this disease, so I find your blog posts to be provocative at best and perhaps rather reckless despite your medical credentials.  Do you have any recent follow-up on your initial anecdotal report?

    Being as I see no further follow-up on this one patient back in 2007, I'll just add that I had my vitamin D levels checked in September and they were low, so I decided to try Dr. Davis's idea.  On 10K IU of D3 I achieved normal vitmain D levels.  Unfortunately, in the last 6 months my AS has progressed with my valve opening going down from 1.1 to 0.9cm.  I still am asymptomatic but will have another echo in 4 months.  My cardiologist is concerned as my left ventricle also increased in size from 5.6 to 6.8cm in 6 months. I'll give the D3 another 4 months, but so far, it appears not to be helping at best and perhaps is accelerating the progression of my AS.

  • William Ball

    7/8/2009 2:28:57 AM |

    Further follow-up on my case.  Today I just got back from Stanford where I had another echo and met with Dr. Craig Miller, Chief of Cardiothoracic Surgery, to discuss my options.  My valve has further stenosed down to 0.7cm from 0.9 only 3 months earlier.  So, despite healthy doses of vitamin D, it looks like, if anything, the calcification of my valve has accelerated. This really points out how a single anecdotal report can be rather misleading.  Although I can believe that the patient's AS in the original report may have receded, there is no way you can attribute this to vitamin D.  It could be a completely unrepeatable coincidence.  Dr, Davis, with all due respect for your good intentions and the benefit you may otherwise provide to your patients, you really ought to remove your case report until you have some more concrete, repeateable evidence.  It not only may not have helped me, but it may have harmed me.

    William--

    Sorry to hear about your valve "progression."

    My experience is not one patient, but around 20. Most have shown either modest reversal of aortic valve stenosis or stabilization (i.e., no change); two have progressed.

    So your experience is the exception, not the rule, compared to what I am seeing. I cannot claim that vitamin D is the "cure all," but I believe this phenomenon can teach us some interesting lessons.

    By the way, your disease, I believe is just showing the natural progression. Small leaps in severity like this are not uncommon in the absence of vitamin D.

    There are some people who's bodies are predisposed to use vitamin d the wrong way. Here's a link to one page that can take you to the research on this subject.

    Dr. Davis,
    Following the previous post from 'anonymous' I would add this comment in support of Bills thoughts that your posts may be 'reckless'.

    There is some evidence that vitamin D can actually CAUSE aortic valve calcification, both in animal models (see The Journal of the American College of Cardiology 2003, Volume 41, Issue 7, Pages 1211-1217: Experimental aortic valve stenosis in rabbits) and in human patients (see Heart 2001, Volume 85, pages 635-638: The vitamin D receptor genotype predisposes to the development of calcific aortic valve stenosis). In this case, you should be very careful in extrapolating your observations of one patient (perhaps with unusually low LDL) to a blanket 'vitamin D restoration' model. It could cause deterioration in the health status of those who seek your expertise without a proper diagnosis.
    A good PubMed search will provide the necessary literature for you to research (rather than speculate) on the mechanism for vitamin D's effect, and may help you to follow the ongoing debate about the validity of the animal model.

  • Dr. William Davis

    10/19/2009 8:51:52 PM |

    Anon--

    I believe you are confusing two things: vitamin D at physiologic replacement levels (as we do in humans) and vitamin D at toxic, supraphysiologic levels (as in rats and mice).

    Like any hormone, too little is not good, too much is not good. We want just right to obtain the benefits.

  • Anonymous

    10/20/2009 10:12:52 AM |

    Hi again Dr. Williams,

    forgive me for pushing you on this, but I am not confusing two things at all.

    One should, of course, always be cautious when extrapolating animal studies to humans and, while the supraphysiological (toxic) levels shown in some animal models is a potential issue (though also debatable, as physiological - or nutritionally relevant - levels CAN induce valve stenosis in mice with sub-optimal lipid metabolism), the main issue is that we are beginning to understand the complexity and potential danger of untested 'nutritional supplements' because of the wide genetic variation that exists in any population (see the second reference I provided for you comparing 630 HUMAN patients). Further, there is very little data on what actually represents 'toxic' levels in humans who take complex multivitamin mixtures, regardless of geographic considerations, environmental load and preexisting baseline blood concentrations (e.g., would you advise selenium supplementation for someone living in Nebraska?).

    This is perhaps demonstrated by your own reports of "around 20" patients (the complete statistics for which I would be interested to see). What is meant by "modest reversal or stabilization in most"? Is not the "around" 10% who have regressed worthy of your interest? I would have thought that without a recovery in all of your patients, you may consider that you are indeed "getting your hopes up prematurely" and that you may be more keen to understand the biochemistry behind the failures. Perhaps you could secure funding to follow these patients in a well designed scientific study? There must be other doctors with similar experiences who would be keen to push the science forward and take it out of the realm of anecdote?

    While I absolutely agree with you that prevention is better than intervention (I saw an excellent seminar just yesterday from professor Richard Cooper [from Loyola Chicago] demonstrating how just reducing salt intake can have dramatic effects on heart health in most people, and Professor Valentin Fuster [Mount Sinai] knows how a good exercise regime can reverse coronary desease). And while I also don't like the 'statin-and-stent' mentality (do statins work at all in women??), I also believe that drug disposition and pharmacokinetics are incredibly important.

    I simply think that you should place an enormous caveat on any of your posts that suggest that supplements such as vitamin D (and perhaps K, A, E, C, selenium etc. etc.) might be a 'magic bullet'. None of them is when applied across the board. In fact, there is strong, reputable and repeatable science that demonstrates potential damage caused by some of these unregulated concoctions that are marketed as 'healthy' (the topic of another of your 'scam' posts when applied to health foods).

    You are absolutely correct that the vitamin D phenomenon "can teach us some interesting lessons", but you are not the first person to have noted this idea and it is being investigated in fairly comprehensive studies. When the results are in, perhaps we will have a better understanding of the types of patient for whom it would work (and those for whom it may be dangerous).

    As with other eminent 'web-doctors' (e.g., Dr. Mercola, who advises vitamin D instead of the flu vaccine, or those who push "vitamin B17" instead of cancer chemotherapy), I would suggest that a blog is not a good place to practice science or medicine and I would hope you would regularly advise your readers to go to a good doctor in their area who perhaps agrees with your alternative methodologies for a full and well considered diagnosis.

    First of all, it's Dr. Davis, not Williams.

    Second of all, I agree with one of your points: This is the Heart Scan BLOG, not the Heart Scan Journal, not the Heart Scan List of Facts. It is a BLOG--pure and simple.

    Hi Dr. Davis (apologies for the previous mistake),

    I wanted to point out that I enjoy your Blog and I share your interest in a nutritional basis for the prevention of cardiovascular disease. However, you allude in your various blogs to several of the unanswered issues behind our understanding of a highly complex topic. Salt reduction, resveratrol, caloric restriction and the enormous array of vitamins provide clear benefits for some people and yet seem to have almost no effect (or, when combined carelessly, even a detrimental effect) on others.

    Based on your last response, I have a final comment on this "more on aortic valve disease and vitamin D" post on your 'blog - not advice'. Then you can choose to be incensed by it, or take it as it is meant - a comment from a concerned cardiovascular research scientist who would dearly like to see these alternative approaches brought into the mainstream.

    Whether you accept responsibility for it or not, it is clear that some people read your postings and act on your "musings". You are, after all, a cardiologist and seen as an expert in medical matters. Further, you and I both know that the vast majority of people neither have access to nor the potential to understand the scientific literature, so the internet has become a frequently dangerous tool by which millions get their information and advice.

    In this thread alone, there are people asking for (and receiving) specific advice on the type of vitamin D to acquire (gel caps) and the purported optimum dosage (anywhere from 4000-8000 units per day). Further, while you don't actually tell him to, William Ball was clearly following what he perceives as 'Doctor's advice' when he "decided to try Dr. Davis's idea".

    His subsequent decline was then 'diagnosed' by you as likely being a "natural progression", even though he states that his vitamin D levels were "normal". This was apparently after taking 10,000 IU per day? Perhaps Mr. Ball would have been interested to know that 10,000 IU is the figure proposed by Hathcock et al., in 2007 as being the upper tolerance limit for humans [Am. J. Clin. Nutr. 85 (1): 6–18] - and should perhaps raise alarm bells.

    There were several opportunities for you to make more clear that this is just "a blog" and should not be used as an alternative for sound medical advice. There is a lot still unknown about this topic and while "not your problem" (and to use your words) there are plenty of people "stupid enough to make more of" your post that you might wish.

    I have several friends for whom I have great concerns because they follow potentially dangerous alternative health approaches based on the "knowledge" they glean from the internet. One friend takes potentially toxic doses of the cyanide compound 'vitamin' B17 to prevent cancer. I have family members who have not vaccinated their children because they KNOW vaccines cause autism. Another refuses to use toothpaste and spends a fortune on bottled water because fluoride will reduce his IQ and give him cancer.

    Big Pharma is now seen almost universally as demonic and conspiracy theories abound. According to such theories, without the influence of doctors, scientists and pharmaceutical companies, we would already be living in a world without cancer and cardiovascular disease - but we are hiding the answers for the sake of profit. While you clearly hold some cynical views about the profitability of the 'conventional treatment' of heart disease, most doctors are doing the best they can under hugely difficult circumstances (and in the face of patients refusing to change bad behavior). We can only hope that the future is brighter as a result of the research being conducted on the alternative preventive measures to which you subscribe.

    In the meantime, as a doctor, you should perhaps be more aware of your influence and how blindly some people will follow your advice, whether you think you have given it or otherwise.
