Boy, was I wrong!

Around 10 years ago, I was talking to a balloon and stent manufacturer's representative, who was raving about some new device that was due for release to the market. Back then, the sky seemed the limit to cardiac device manufacturers, who were falling over themselves scrambling to design and market the next new device.

The angioplasty market then had ballooned (no pun intended) from nothing to a multi-billion dollar industry. Stents were just getting underway but clearly had potential for being at least as large.

But this was a time when preventive therapies were also beginning to get quite powerful. We had just gotten started doing CT heart scans and were excited about the possibilities, statin drugs were gaining evidence through clinical trials, and the power of many nutritional supplements was finally achieving validation. We were even learning the error of our prior low-fat ways.

So I broadly pronounced to the enthusiastic product representative, "In 10 years, balloons, angioplasty, and stents will occupy this little corner of cardiac care because prevention will have become so powerful. We won't talk about heart procedures. We'll talk about coronary plaque regression!"

I even advised the representative that he should consider a career change in anticipation of the coming wave of preventive strategies.

Was I ever wrong. Despite the power of heart disease prevention--which is indeed true--cardiac device and procedure technology has boomed, both in popularity as well as in revenue success. Device manufacturing and sales are hugely successful. Implanting devices into people is a hugely profitable enterprise.

Since my ill-timed comments to the salesman, Boston Scientific, a major manufacturer of stents and other cardiac devices, reported revenues of $6.2 billiondollars in 2005, a 12% increase over the prior year. Medtronic reported 2005 revenues of $11.3 billion, growing at 15% per year. Clearly, cardiac procedures are still quite popular--and profitable.

My timing was off, but not for long. The huge crest of change in preventive therapies is upon us. That's the premise behind the Track Your Plaque concept: heart disease prevention can't be found in a hospital, is not supported by cardiac device manufacturers, and is not being advocated by most cardiologists or primary care physicians. Yet the tools are getting better and better every day.

Those of you who succeed in halting or reducing your heart scan score are extremely unlikely to add to Boston Scientific's or Medtronic's revenues. Help me spread the word.

Don't forget how dangerous heart disease can be

Sometimes it's easy to get smug when coronary plaque is a reversible process.

When you see people day in, day out, week in, week out, drop their heart scan scores, reversing what could be a dangerous disease, you can sometimes lose sight of just how dangerous coronary disease can be.

Whether I like it or not, I maintain a reasonably active role in hospitals out of necessity. I do need their services occasionally for people with advanced heart disease when I meet them (when regression is not the initial conversation for safety reasons), or valve disease is diagnosed, or someone shows up with congenital or heart muscle diseases. In other words, although we focus on coronary issues, there's more to heart disease than just coronary disease.

This unfortunate case just served to remind me how powerful coronary disease can be. Elizabeth, an active 67-year old, finally came to the hospital after suffering 6 months of chest pain and increasing breathlessness. She hated hospitals and hadn't seen a doctor in 30 years since she was successfully treated for cancer.

In those 30 years, she'd been quite active with family and a small business. But she also smoked 2 packs of cigarettes most of those years.

After she was admitted to the hospital, it became clear that Elizabeth had experienced one, if not several, heart attacks along the way. The entire front 2/3 of her heart was non-functional. If that wasn't bad enough, two of her heart valves were severely diseased and dysfunctional: Her aortic valve barely opened (aortic valve "stenosis", or stiffness) and the mitral valve leaked severely (mitral valve "insufficiency", or leakiness). All of this was confirmed with conventional testing in the hospital, including a heart catheterization.

Elizabeth ended up in emergency surgery--very unusual, by the way, for valve surgery of the sort she had--but died in the first few hours after her procedure. Her heart had simply been too damaged from her heart attacks, and the extraordinary stress of surgery that included two valves was too much. She died on the ventilator.

Coronary disease is a very serious matter. When I see cases like Elizabeth, it boosts my commitment to tell everyone that heart disease--when identified early enough--is a controllable, preventable, even reversible process. For poor Elizabeth, she was much too far down the path of severe, irreversible disease that control or reversal was simply not an option. She was in imminent danger of dying even upon arrival.

It's exciting yet sometimes frightening to know what you have in your hands: The means to control this monster called coronary disease. Use it wisely. But don't lose sight of what it can do it you permit it to grow, fester, and explode.

How many ways can you disguise sugar?

I came across this shockingly silly report on AOL, who obtained their info courtesy Health Magazine:

The Best New Healthy Foods for Busy People
from Health


The foods on their list:

Kettle Brand Bakes Hickory Honey BBQ--the healthy claim is based on the lack of trans-fatty acids and low-fat.










Post Healthy Classics Raisin Bran Cereal Bars, Cranberry--Likewise, low-fat, sweet, and addictive means healthy to these people.




Amy’s Mediterranean Pizza With Cornmeal Crust --Please!!



Horizon Organic Colby Cheese Sticks --Because it's made by cattle without use of growth hormone or antibiotics, they declare this healthy. I guess we can ignore the saturated fat content and high total fat content.

100% Whole Grain Chips Ahoy! Cookies --You mean we can add the bran back to wheat products and make it healthy?!


This kind of mass-market marketing trickery leaves me incredulous. Don't believe it for a moment. This is typical of the food industry: Take one aspect of nutrition that is truly healthy, such as high-fiber, or low-fat, or organic. Then add undesirable, unhealthy ingredients. The current fad is to add lots of sugar and or sugar-equivalents (usually flour and other wheat products). Because there's one healthy ingredient, they'll call the end-product healthy, too.

If you want to see what health looks like if you indulge in "healthy" products like this, just look up and down the grocery aisles at your neighborhood grocery store. You're likely to see the results: Gross obesity, diabetes, and arthritis.

You won't, of course, see the huge acceleration of growth in coronary plaque, but it's there, ticking away.

To remind us what ideal body weight is: Watch an old movie!

Jack was skeptical. At 273 lbs, 5 ft 11 inches, he felt that he was "just right".

"I feel fine. I don't see why you think I should lose weight," he declared. "In fact, when I lost 25 lbs a couple of years ago, everyone said I was too skinny!"

I showed Jack why: He had an HDL of 35 mg/dl, small LDL (over 90% of all LDL particles), an elevated blood sugar of 123 mg/dl (diabetes is officially 126 mg/dl or greater), high blood pressure, and increased inflammation (C-reactive protein). These were all manifestations that his body weight was too much for it to handle.




So I told Jack that we've all forgotten what ideal weight should look like. Our perception of "normal" has been so utterly and dramatically distorted by the appearance of our friends, family, co-workers, and other people around us that we've all lost a sense of what a desirable weight for health should be.




So I suggested to Jack that, if he wanted to rememember what ideal weight is and what people are supposed to look like, just watch old movies.

Old movies, like the 1942 production of Casablanca, or the 1952 production of Singin' in the Rain, show the body build that was prevalent in those days. Look at Humphrey Bogart or Gene Kelly--men with average builds, weighing 140-160 lbs--that's how humans were meant to look.

A report this morning on the Today Show showed the "after" photos of several people following bariatric (weight reduction) surgery. The "after" pictures, from the perspective of ideal weight and ideal health, remain hugely overweight.

We need to readjust our perceptions of weight. The average woman in the U.S. now weighs 172 lbs(!!!). Don't confuse average with desirable.

Diabetes is a choice you make

Tim had heart disease identified as a young man. He had his first heart attack followed by a quadruple bypass surgery at age 38. Recurrent anginal chest pain and another small heart attack led to several stents over three procedures in the first four years after bypass.

Tim finally came to us, interested in improving his prevention program. You name it, he had it: small LDL, low HDL (28 mg/dl), lipoprotein(a), etc. The problem was that Tim was also clearly pre-diabetic. At 5 ft 10 inches, he weighed 272 lbs--easily 80 or more pounds overweight.

Tim was willing to make the medication and nutritional supplement changes to gain control over his seeminglly relentless disease. He even turned up his exercise program and lost 28 lbs in the beginning. But as time passed and no symptoms recurred, he became lax.

Tim regained all the weight he'd lost and some more. Now Tim was diabetic.

"I don't get it. I eat good foods that shouldn't raise my insulin. I almost never eat sweets."

I stressed to Tim that diabetes and pre-diabetes, while provoked acutely by sugar-equivalent foods (wheat products, breads, breakfast cereals, crackers, etc.), is caused chronically by excess weight. If Tim wants to regain control over his heart disease, he needed to lost the weight.

Unlike, say, leukemia, an unfortunate disease that has little to do with lifestyle choices, diabetes is a choice you make over 90% of the time. In other words, if you become diabetic (adult variety, not children's variety) as an adult, that's because you've chosen to follow that path. You've neglected physical activity, or indulged in too many calories or poor food choices, or simply allowed weight to balloon out of control.

But diabetes is also a path most people can choose not to take. And it is a painfully common choice: Nearly two-thirds of the adults in my office have patterns of pre-diabetes or diabetes when I first meet them.

Let me stress this: For the vast majority of adults, diabetes is a choice, not an inevitability.

I'll call the doctor when I feel bad!

Max just had his heart scan. He sat down with the x-ray technologist at the work console while she pointed out the white areas in his coronary arteries that represented plaque.

"It looks like you're going to have a fairly high score," the technologist commented. "The final report will be available after one of our cardiologists reviews your images."

Max shrugged. "Well, I don't feel anything. I'm always running around with work, with my kids, stuff like that. That's better than any stress test. I guess I'll worry about it if it starts to bother me."


You'd be surprised how common this view remains: If it's not bothering you, then just forget about it. It's easy to do, since you have no symptoms, nothing to impair your physical activities. But what are the potential consequences of ignoring your heart scan? Here's a few:

--Prevention and plaque reversal efforts are most effective the earlier you start. From a heart scan score viewpoint, the lower your starting score, the easier it is to gain control over it. More people will succeed in reducing their score when the starting score is lower.

--The role of prevention of heart disease instantly crystallizes when you know your score. Your LDL cholesterol of 142 mg/dl or HDL of 41 mg/dl no longer seem like just numbers of borderline signficance. Instead, they become useful tools to gain control over plaque. They cast your numbers in a new and clear light.

--Knowing your heart scan score today gives you a basis for comparison in future. Your score of, say 250, today, can be 220 in one year. Without your preventive efforts, it will be 30% higher: 325. That's a big difference!

--Sudden death or heart attack--can occur in up to 35-40% of people with hidden heart disease--without warning.

Don't even bother getting a heart scan if you're going to ignore it. I've said it before and I'll say it again: A heart scan is the most important health test you can get--but only if you do something about it.

Coenzyme Q10 and statin drugs

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

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

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

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.

What's for breakfast?

Breakfast, for some reason, seems to be the toughest meal of the day for many people.

I think it's because the quest for sweet has dominated the American breakfast for so long, with its half-century legacy of cartoon character-festooned breakfast cereals; baked flour products like pancakes, waffles, and English muffins; more recently, "healthy" alternatives like bran muffins and oat waffles.

This breakfast lifestyle has also contributed to the obesity and diabetes ("diabesity") epidemic. Breakfasts of wheat- or corn-based cereals, even those labeled "heart healthy," fruit, and whole grain breads are guaranteed paths to low HDL cholesterol, high triglycerides, flagrant small LDL, increased inflammatory responses, high blood pressure, and higher blood sugar. Such foods also make you tired, make your abdominal fat grow (wheat belly), and increase appetite so that you want more.

So what can you eat for breakfast that doesn't provoke these patterns?

I will never pretend to be terribly clever in creating meal menus, but I can tell you what has worked for me and many of my patients. Be warned: It may require you to suspend your previous notions of what "should" be included in a list of breakfast foods.

Here are some examples that you may find helpful:

--Raw nuts--one or several handfuls of raw almonds, walnuts, pecans, pistachios
--Cheeses--the real, traditional sorts like gouda, goat, Swiss, edam, etc. (not Velveeta, Cheez Whiz, etc.)
--Eggs, Egg Beaters--and "spice" them up with sun-dried tomatoes, salsa, olives, tapenades, olive oil, onions, green peppers, etc.
--Yogurt (real, of course), cottage cheese
--Ground flaxseed, oat bran--as hot cereals or added to yogurt, cottage, or other foods. Esp. helpful for reducing both total LDL and the proportion of small LDL.
--Oatmeal--slow-cooked, not the instant nonsense.
--Soups--great for winter.
--Dinner foods--chicken, beef, fish, green beans, asparagus, tomatoes, etc., most easily added by saving left-overs from dinner. You'll be surprised how filling dinner foods eaten at breakfast can be.

It's really not that tough. It just means selecting from an entirely different list of foods than you might be accustomed to.

The first lawsuit?


The closing arguments in actor John Ritter's wrongful death lawsuit are over and the two doctors charged with negligence cleared, five years after his death from a dissection (tear of the inner lining) of the thoracic aorta. The family sought $67 million in damages, claiming that the aortic dissection was misdiagnosed as a heart attack and that the enlarged aorta should have been reported to Mr. Ritter two years earlier during a full body scan.

The AP story can be viewed at http://ap.google.com/article/ALeqM5gmv6HnJJPBee2gWgEYResT5m6YkAD8VDF9CO0


Well, perhaps this is the start of a trend. Up until now, it has been commonplace for doctors to ignore many of the important findings on heart scans, full body scans, and similar direct-to-the-public imaging services. For instance, similar to John Ritter's case, enlarged thoracic aortas are commonly ignored. I'd even say that as a rule they are ignored. I have seen many patients in consultation who have had large aortas identified on heart scans, yet nothing--not a thing--was done about it. While the doctors escaped a lawsuit this time, it might not happen a second time.

I truly hope that Mr. Ritter's unfortunate experience and the consequent lawsuit do not trigger the usual defensive medicine response of resorting to major procedural "solutions."

A better response would be to 1) identify the problem--enlarged aorta in this case, 2) identify the causes, then 3) correct the causes. It does not necessarily mean that a major procedure like replacing the aorta (a horrendous surgery, by the way) needs to be pursued each and every time.

It is possible that Mr. Ritter's lawsuit is just the first. Over the next several years, it could trigger an avalanche of lawsuits for all the neglected findings on tests like heart scans, body scans, and other imaging methods that are gaining expanded direct-to-consumer access.

The origins of heart catheterization: Part II

On the afternoon of October 30th, 1958, nearly 30 years after Werner Forssmann’s fumbling attempts, Dr. Mason Sones, a 5 foot 5 inch, plain-talking, cuss-every-few-words, cigarette-wielding radiologist at the Cleveland Clinic, was performing a routine angiogram of a patient’s aorta (the large vessel emerging from the heart) in a dark basement laboratory. (In Sones’ day, imaging methods remained primitive, disease diagnosis relying more than anything else on the physician’s powers of observation and crude diagnostic procedures. Abdominal pain was assessed with exploratory laparotomy, headaches with air injected into the brain and nervous system (“pneumoencephalography”), an excruciatingly painful ordeal. Being able to track the course of x-ray dye injected into specific internal organs, whether liver, biliary tree, aorta, lungs, or coronary arteries, represented a huge advance in diagnostic tools for human disease.)

In 1958, no one had yet injected dye directly into the coronary artery of a living human.


Just as the dye injector was triggered, Dr. Sones’ eyes widened in horror when the black and white monitor showed that the catheter had inadvertently jumped into the right coronary artery. The injection pump, already triggered to release its load, proceeded to pump 30 cc of X-ray dye straight into the artery. (Modern techniques usually require only 5–10 cc of dye.) Dr. Sones recounts the incident:

“It was late in the day and we were tired. I hit the switch to rev up the x-ray generator so I could see. As the picture came on, I could see that the damn catheter was in the guy’s right coronary artery. And there I was, down in the hole [a recess to shield him from radiation]. I yelled, “Pull it out! Pull it out!”*? By that time, about 30 cc of the dye had gone into the coronary artery. I climbed out of the hole and I grabbed a knife. I thought that his heart would fibrillate and I would have to open his chest and shock his heart. [In Sones’ day, modern CPR hadn’t yet been developed as a method of resuscitation.] But he didn’t fibrillate—his heart stopped. I demanded he cough. He coughed three times and his heart began to beat again. I knew at once that if the heart could tolerate 30 cc of dye, we would be able to safely inject small amounts directly into the coronary artery. I knew that night that we would have a tool to define the anatomic nature of coronary disease.”


*An observer, Dr. Julio Sosa, reported that Dr. Sones, in his shock, also blurted, “We’ve killed him!” After all, conventional wisdom of that era, based on observations from dye injections into the coronary arteries of dogs, was that injecting x-ray dye into human coronary arteries would result in immediate death from the electrical imbalance provoked in heart muscle momentarily deprived of oxygen-carrying blood.

Thus it was established that it was indeed possible to directly inject x-ray dye into human coronary arteries and reveal its internal contours. That’s not to say that the x-ray dyes of 1958 were innocuous. Far from it. In addition to briefly interrupting heart rhythm, as happened with Sones’ first accidental attempt, the dyes used then typically caused dizziness and the sudden urge to vomit. During the first 30 years of direct coronary catheterizations, it was common for hospital staff to run to the patient’s side, bucket in hand to catch the inevitable vomit, once the heart was jump-started by coughing.

Not surprisingly, Dr. Sones’ discovery set off both an avalanche of criticism and bold predictions of how the new technique might change the course of diagnosis in heart disease.

Over the subsequent weeks and months, Dr. Sones proceeded to purposefully insert catheters into coronary arteries and create angiograms that revealed the extent of coronary atherosclerosis. He learned how to fashion new catheter shapes to facilitate access to the arteries. Sones developed an impressive experience in the new technique. For the first time, clear images of the coronary arteries were routinely obtainable for the confident diagnosis of coronary atherosclerosis before death. Dr. Sones became an unlikely celebrity in Cleveland, entertaining physicians from around the world eager to learn about his methods, politicians and celebrities, even Middle Eastern nobility complete with bodyguards and food testers.

Dr. Sones continued to work in Cleveland, furthering the techniques of heart catheterization after his fortuitous error. He died of lung cancer in 1985, 17 years after his discovery.

Thus was born the modern age of heart catheterization.

Today, over 10,000 heart procedures are performed in the U.S. every day, 365 days a year, the vast majority of which involve heart catheterization or begin with a heart catheterization. Dr. Sones' fortuitous blunder was followed by 30 years of productive refinement and development before the blatant excesses of this technique really began to be exploited.

The origins of heart catheterization: Part I

The modern era of heart disease care was born from an accident, quirky personalities, and even a little daring.

The notion of heart catheterization to visualize the human heart began rather ignominiously in 1929 at the Auguste-Viktoria Hospital in Eberswalde, Germany, a technological backwater of the day. Inspired by descriptions of a French physician who inserted a tube into the jugular vein of a horse and felt transmitted heart impulses outside the body, Dr. Werner Forssmann, an eager 25-year old physician-in-training, was intent on proving that access to the human heart could be safely gained through a surface blood vessel. No one knew if passing a catheter into the human heart would be safe, or whether it would become tangled in the heart’s chambers and cause it to stop beating. On voicing his intentions, Forssmann was ordered by superiors not to proceed. But he was determined to settle the question, especially since his ambitions captured the interest of nurse Gerda Ditzen, who willingly even offered to become the first human subject of his little experiment.

Secretly gathering the necessary supplies, he made his first attempt in private. After applying a local anesthetic, he used a scalpel to make an incision in his left elbow. He then inserted a hollow tube, a catheter intended for the bladder, into the vein exposed under the skin. After passing the catheter 14 inches into his arm, however, he experienced cold feet and pulled it out.

One week later, Forssman regained his resolve and repeated the process. Nurse Ditzen begged to be the subject, but Forssmann, in order to allow himself to be the first subject, tricked her into being strapped down and proceeded to work on himself while she helplessly watched. After stanching the oozing blood from the wound, he threaded the catheter slowly and painfully into the cephalic vein, up through the bicep, past the shoulder and subclavian vein, then down towards the heart. He knew that simply nudging the rubber catheter forward would be sufficient to direct it to the heart, since all veins of the body lead there. With the catheter buried 25 inches into his body, Forssmann untied the fuming Ditzen. Both then ran to the hospital’s basement x-ray department and injected x-ray dye into the catheter, yielding an image of the right side of his heart, the first made in a living human.



Thus, the very first catheterization of the heart was performed.



An x-ray image was made to document the accomplishment. Upon hearing of the experiment, Forssmann was promptly fired by superiors for his brazen act of self-experimentation. Deflated, Forssmann abandoned his experimentation and went on to practice urology. He became a member of the Nazi party in World War II Germany and served in the German army. Though condemned as crazy by some, physicians in Europe and the U.S., after hearing of his experience, furthered the effort and continued to explore the potential of the technique. Forssmann himself was never invited to speak of his experiences outside of Germany, as he had been labeled a Nazi.

Many years after his furtive experiments, the once intrepid Dr. Forssmann was living a quiet life practicing small town medicine. He received an unexpected phone call informing him that he was one of three physicians chosen to receive the 1956 Nobel Prize for Medicine for his pioneering work performing the world’s first heart catheterization, along with Drs. André Cournand and Dickinson W. Richards, both of whom had furthered Forssmann’s early work. Forssmann remarked to a reporter that he felt like a village pastor who was made a cardinal.

Strange, but true.

Conventional therapy vs. alternative therapy

Rose is a 75-year old woman, mother of four, grandmother of many more.

Rose's story started after a heart attack 18 months ago that resulted in two stents. She was advised to follow an American Heart Association diet and take Lipitor. However, some months later, after her fourth stent, she became disilluioned in the conventional approach to heart disease and sought alternative therapies to help reduce or reverse her heart disease.

She found an alternative health practitioner who advised chelation, antioxidant vitamins for "excessive oxidation," and several homeopathic preparations.

Nothing was said about diet or exercise. Nothing was said about the baked flour products and pastries that occupied at least two meals every day. Nothing was said about the candies she indulged in several times per day, nor the soft drinks. Nothing was said about the wildly fluctuating blood sugars, poorly controlled by an oral diabetes agent. Thirty pounds of weight gain over the past 5 years with no exercise or physical activity? No comment here, too.

In short, Rose was the "graduate" of the conventional approach, as typically offered nationwide thousands of times a week. She was also the recipient of the insight of at least one alternative health practitioner, eager to reject conventional notions of how to achieve heart health.

So I then met her. She was experiencing chest pains every day, several times per day. Blood pressure over 200. At 5 ft, 3 inches, weight: 186 lbs.

Initial laboratory results:

HDL cholesterol 42 mg/dl
LDL 132 mg/dl
Triglycerides 263 mg/dl
Blood sugar 173 mg/dl


You can fill in the rest. In short, Rose was a disaster. Despite the attentions of several professionals from both the conventional as well as alternative camps, she was careening rapidly towards failure. She'd been given various crutches, Band-Aids, and salves, none of which resulted in any possibility of long-term relief from her aggressive disease.

My point: As I've said previously, all we want is truth. We want effective, rational approaches that yield real benefit. A stent? All that provides is temporary restoration of blood flow. Statin agents? They do indeed reduce LDL cholesterol. But what if Rose has 8, 9, or 10 other causes of heart disease unaffected by the statin drug? It will do little or nothing.

Nobody had addressed many of the root causes of Rose's disease: insulin resistance, high triglycerides, inactivity, obesity, hypertension (and identifying the reasons why her blood pressure was so high), vitamin D deficiency (virtually guarantted to be severe), junk foods including the ones known as "whole grains."

My message: Success in heart disease, as well as all aspects of health for that matter, doesn't necessarily have to come from an "alternative" approach, nor a "conventional" approach. It comes from applying what is truly effective, regardless of what label someone applied to it.

I would no sooner trust my health and life to an alternative health practitioner hawking unusual herbs and remedies than I would submit to a heart catheterization, three stents, followed by a statin drug. There's small benefit in both approaches, but none are the best. You've got to look elsewhere for that.

The JELIS Trial

The Japan eicosapentaenoic acid (EPA) Lipid Intervention Study (JELIS) is a clinical trial that all Track Your Plaquers should know about.

This enormous trial followed a simple design:

Japanese men, between 40-75 years, and Japanese postmenopausal women aged <75 years with total cholesterol 250 mg/dl or greater were enrolled. A total of 18,645 subjects (mean age, 61 years; 31% male) participated: 36% had hypertension, 15% had diabetes, and 20% had coronary disease (history of heart attack or heart procedure). Average starting total cholesterol 275 mg/dl; LDL 180 mg/dl. All participants were treated with pravastatin 10 mg/day or simvastatin 5 mg/day; approximately half also received the omega-3, EPA, 1800 mg/day, in addition to one of the statin drugs.

Treatment resulted in an average LDL reduction of 26% in all participants; the group taking EPA experienced an additional 10% reduction in triglycerides. All major cardiovascular events were tracked and tabulated, including sudden cardiac death, fatal or nonfatal myocardial infarction (MI), unstable angina pectoris, coronary artery bypass surgery, and coronary angioplasty.

After nearly five years, 3.5% of statin-only participants experienced an event; 2.8% of statin + EPA experienced an event. The (often misleading and frequently abused value) "relative reduction" was therefore 19%.

There are several features that make the JELIS trial interesting:

--There were an unusually low number of cardiovascular events in the entire group, lower than nearly all American and European trials of similar design. This likely points to the greater burden of atherosclerotic heart disease in the U.S. compared to Japan. Rates in comparable U.S.-based trials usually range from 6-14%, sometimes more.

--Both the participants without identified heart disease at enrollment and those with heart disease at enrollment obtained a similar magnitude of beneficial reduction in cardiovascular events.

--There was an unusual preponderance of women--69%--unlike most other trials of cardiovascular events. We might therefore argue that JELIS most conclusively showed that benefits of EPA are most confidently demonstrated for females.

--A fish oil preparation containing only EPA was used, rather than the usual EPA + DHA. There are discussions from some corners that argue that DHA is more important than EPA, e.g., algae sources. However, JELIS would argue that EPA does play a role. Is EPA with DHA better, worse, or no different? Unfortunately, there are insufficient data--large, randomized data like JELIS--to help us. Recall that GISSI Prevenzione used a combination of EPA and DHA, as have virtually all other trials examining the effects of fish oil. Also, keep in mind that the epidemiologic observations of the cardiovascular benefits of eating fish suggest that the naturally-sourced omega-3s--a combination of EPA and DHA--are associated with benefit.

--It's surprising that any difference at all was demonstrated, given the high intake of fish in the Japanese. In fact, blood levels of EPA in participants before taking EPA was five-fold higher than in western populations.


One potential difficulty: The study was funded by the manufacturer of the EPA preparation used, Mochida Pharmaceutical Company. We all know what that can do to results.

Nonetheless, the JELIS trial is a study that adds to the emerging wisdom in fish oil.

Omega-3 MUST be from fish oil

Despite my rants in this blog and elsewhere, at least once a day I'll have a patient say, "I cut back (or eliminated) my fish oil because I get my omega-3s from _______ (insert your choice of flaxseed oil, walnuts, yogurt, mayonnaise, bread, etc.)."

(See prior Heart Scan Blog post: Everything has omega-3.)

When I point out to them that the "omega-3s" in these products are not the same as the EPA and DHA from fish oil, they invariably declare, "But it says so here on the label: 'Contains 200 mg of omega-3 fatty acids'!"

Apparently, some of my colleagues have even endorsed this concept of replacing the omega-3s from fish oil with these "alternatives."

It's simply not true. The linolenic acid that is being labeled as omega-3, while it may indeed provide health benefits of its own, cannot replace the EPA and DHA that fish oil provides.

The most graphic example of the differences between the two classes of oils is in people with a condition called familial hypertriglyceridemia. People with this condition have triglyceride levels of 400, 600, even thousands of mg/dl--very high. Fish oil, usually providing EPA and DHA doses of 1800 mg per day and higher, reduce triglycerides dramatically. A person with a starting triglyceride level of, say, 900 mg/dl, may take 2400 mg of EPA and DHA from fish oil and triglycerides plummet to 150 mg/dl. This person then decides to replace fish oil with a linolenic acid source like flaxseed oil. Triglycerides? 900 mg/dl--no effect whatsoever.

Familial hypertriglyceridemia represents an exagerrated example of the differences between the two oils. Even if you don't have this genetic condition, the differences between the oils still apply.

EPA and DHA are activators of the enzyme, lipoprotein lipase, that accelerates clearance of triglycerides from the blood. Linolenic acid from flaxseed oil, walnuts, and other food sources does not. EPA and DHA block after-eating (post-prandial) accumulation of food by-products that can contribute to coronary and carotid plaque. Linolenic acid does not. EPA and DHA block platelets, reduce fibrinogen, and exert other healthy blood clot-inhibiting effects. Linolenic does not.

The 11,000-participant GISSI-Prevenzione Trial that showed 28% reduction in heart attack, 45% reduction in cardiovascular death with omega-3s used . . . fish oil.

The 18,000 participant JELIS trial that showed 19% reduction in cardiovascular events when omega-3s were added to statin therapy used . . . fish oil. (Actually, in JELIS, they used only EPA wtihout DHA.)

Linolenic acid is not a waste, however. It may exert anti-inflammatory benefits of its own, for instance. But it exerts none of the triglyceride-modifying effects of EPA or DHA.

EPA and DHA from fish oil and linolenic acid from foods each provide benefits in their own way. Ideally, you include both forms of oils--fish oil and linolenic acid sources--in your daily diet and obtain full benefit from each separate class. But they are not interchangeable.

Osteoporosis and coronary calcium

Several studies over the years have demonstrated a curious paradox:

People with more osteoporosis (thin bones) tend to be more likely to have coronary disease (heart attacks). They also tend to have higher heart scan scores (more coronary calcification as an index of atherosclerotic plaque).

People with more coronary disease and higher heart scan scores tend to have more osteoporosis.



In other words, regardless of which way you tackle the question--osteoporosis first or heart disease first--it leads to the same conclusion: Both conditions are somehow related.

I realize I harp an awful lot on this whole vitamin D issue. But, even after correcting the vitamin D blood levels of many hundreds of people, I remain enthusiastic as ever about the untapped potential of this fascinating factor.

So I couldn't resist showing this amazing comparison of how the long-term effect can be quite graphic.

The first scan is from a 46-year old man and shows normal coronary arteries without calcium and normal density of the vertebra (a common and reliable place to measure bone density).

























The second image is from a 79-year old man with both severe coronary calcification (and therefore severe coronary disease) and severe osteoporosis.
























It makes you wonder if the disordered metabolism of calcium through vitamin D deficiency allows transport of calcium away from bone and into coronaries. This has, however, been shown to not be the case. Instead, they are separate processes, each under local control, but sharing a common pathophysiology (causative factors).

An intriguing question: Would the 79-year old still look like the 46-year old had he begun increasing his vitamin D intake at, say, age 30?

About comment responses and moderation

Just a brief word about my responses to reader comments:

I appreciate the many often insightful and interesting reader comments I receive to the Heart Scan Blog. However, managing them and responding to them has simply become impossible, due to time demands.

I'm afraid that I am unable to answer questions seeking medical advice; this is for your doctor, who knows you and can diagnose and prescribe. I cannot.

I'm also unable to engage in lengthy debates; I've had commenters become very angry when I was unable to engage in lengthy conversations on some topic. Nor am I able to do Google or literature searches for commenters, or review studies, papers, or other materials.

I would urge any readers who wish to engage in in-depth discussions about these issues, talk about lipoproteins, heart disease reversal, etc. to do so on the Track Your Plaque Forums. Yes, it is a fee-for-membership website, a model that has become necessary to pay for the services we provide (not pay me).

I wish that I could answer all the concerns and questions that come my way, but it's simply physically impossible doing so while maintaining a full-time very busy cardiology practice, developing the Track Your Plaque website (which is becoming an enormous responsibility), publishing scientific data, maintaining hospital responsibilities, and spending time with my wife and family. We're all busy and I'm no different. I'm afraid that it's my responses to blog comments that I will have to sacrifice.

I invite commenters to continue to comment on these posts, as I've learned many new things by reading them and find them helpful feedback. And I do read them. Should an especially helpful comment be made, I will feature it in a new blog post, rather than respond directly.

"Flying in the fog"

I received this wonderful response to The Heart Scan Blog post Hammers and Nails:

I am 65 years old. I had a stent inserted in the "widow-maker" artery (80% blockage) a year ago. I had passed out a couple of times (heart rate dangerously low - 30s). I rode to the hospital in an ambulance. Tests revealed short LBBB episodes; mild mitral regurgitation, mild tricuspid regurgitation. Catherization showed 3 vessel CAD. I was told that a medicated stent was absolutely necessary given the situation; regardless, I have to accept that. A pacemaker was installed to prevent bradycardia and keeps heart rate from dropping below 60. I have 20% L distal main blockage and 90% lesion of the high first obtuse marginal at the takeoff. The right coronary had 60% posterior lateral branch stenosis.

Since then I have reduced TG from 360 to 60, LDL from 89 to 82 (although a few months ago it was in the mid-70s), and increased HDL from 30 to 46. I went from 265lbs to 190lbs and hope to eventually get to 180lb this Spring. I did it by progressing from walking to trotting (slow run) and dietstyle changes (low-GI veggies, fruits, etc.) .













On a recent visit the cardiologist said the the LDL needs to be 70 or below to "freeze" the 90% blockage and gave me a prescription for Lipitor. I asked if there were alternatives, like diet, supplements, etc. He admitted that he did not know about those alternative but did know Lipitor. When the only tool you have is a hammer then everything is a nail. I understand that the 90% blockage is important but will not take the Lipitor to achieve the 12 points reduction. Seems like an overkill.

I asked him if there was a way to evaluate my current condition. I was told there was no way. Basically, if I have no symptoms, good. If I have symptoms then it will have to be evaluated. Death could be the only symptom. I swear he was about to say bypass surgery ($$$$$$!) was inevitable. Something is wrong with this "fly-in-the-fog-and-hope-you-don't- hit-a-mountain" approach. Hope is not a strategy!

I am confident that I can reduce LDL to below 70 based on eliminating wheat-products in my diet plus increasing oat bran in my diet. I also take fish oil daily (EPA/DHA-2g). I am looking for a new cardiologist. I just recently purchased your book and find it very instructive. In the meantime I have an appointment with my primary care physician to discuss implementing the Track Your Plaque program. I realize that the one stent will skew the scan numbers but can be used as a baseline number.



Phenomenal weight loss! That alone has likely cut this man's risk in half. But is that it? Is the cardiologist correct--take Lipitor and hope for the best?

Of course not. There are many additional strategies to employ. Eliminating wheat from the diet is an excellent idea: HDL will skyrocket, triglycerides drop even further, small LDL will drop like a stone, blood sugar and blood pressure will drop. He will have more energy, get rid of afternoon energy slumps, sleep better.

He has already added fish oil. If his cardiologist did not mention this, I would say he was guilty of malpractice. The data supporting the addition of fish oil to the treatment program of anyone with heart disease is overhwelming. GISSI Prevenzione: 11,000 participants--28% reduction in heart attack, 45% reduction in death from heart attack. The Japanese JELIS trial of 18,645 participants--19% reduction in dangerous heart events. It's also clear that omega-3 fatty acids from fish oil also compound the benefits of statin agents, should this man choose to begin Lipitor.

Vitamin D brought to normal blood levels is his next "secret weapon" that will further boost his lipids and lipoproteins further into not just "normal" territory, but beyond belief. Even though we aim for 60-60-60 for LDL-HDL-triglycerides in the Track Your Plaque program, adding vitamin D can yield numbers you've never seen before. It's not uncommon, for instance, to see a 10 or 20 mg/dl jump in HDL.

Identify all other hidden causes of coronary plaque. If all the causes have not been fully identified, how can anyone hope to gain full control over coronary plaque growth?

Re: LDL cholesterol of 89 mg/dl at the start. Of course, this is a calculated value, not measured. Because HDL was low and triglycerides high at the start of his program, this means that true LDL--if actually measured--was probably more like 180 to 250 mg/dl, and it was probably nearly all small. So his cardiologist might have advised a helpful treatment, though for the wrong reasons.

Our reader has gone a long way on his own in creating his own prevention program. But there's yet more to do, particularly if the goal is reversal. It is shocking to me that a man like our reader, clearly articulate and motivated, gets virtually no advice beyond "take Lipitor" after all the procedural benefits have been reaped.

Even though one artery can no longer be "scored" due to the presence of the metallic stent, a heart scan would still be invaluable for long-term tracking purposes, just as we advocate in the Track Your Plaque program.
