Take a walking vacation

If you're planning a vacation, why not consider a walking vacation?

The concept is really taking off. All you need is a pair of comfortable shoes and an interesting locale. More and more services are popping up to help you plan fun and interesting destinations and itineraries. One such catalog can be found at http://walking.about.com/od/tours/a/walkingvacation_3.htm

Lengthier walks may require some advance planning and toting some supplies. Don't forget the water!

From a health viewpoint, a walking vacation sure beats the heck out of a cruise that packs on 12 pounds of extra weight from the 24-hour a day buffet. If you're in the midst of a weight loss effort, several hours of walking through interesting locales and scenery can make it effortless.

There's loads of neat places to visit from a walker's perspective. One interesting website is www.waterfallwalks.com that lists trails that provide spectacular views of waterfalls.

Another variation on this theme is biking vacations. My wife and I are trying to set the time aside for a biking tour of wineries in the French countryside. That's our kind of multi-tasking!

"Expanded indications for implantable defibrillators"

So reads the headline on a magazine I received recently (along with thousands of my colleagues) from a major hospital system.

It goes on to say: "In January 2005, indications for impl All posts by william-davis

The myth of small LDL

Annie's doctor was puzzled.

Despite an HDL cholesterol of 76 mg (spectacular!) and LDL of 82 mg, her CT heart scan showed a score of 135. At age 51, this placed her in the 90th percentile.

Not as bad, perhaps, as her Dad might have had, since he died at age 54 of a heart attack.

So we submitted blood for lipoprotein testing. Surprise! over 90% of all her LDL particles were small. (By NMR, they're called "small". By gel electropheresis, or the Berkeley Lab test, or VAP (Atherotech) technique, they're called "HDL3".)

What gives? Traditional teaching in the lipid world is that if HDL equals or exceeds 40 mg/dl, then small LDL will simply not be present.

Well, as you can see from Annie's experience, this is plain wrong. Yes, there is a graded, population-based effect--the lower your HDL, the greater the likelihood of small LDL. But small LDL is remarkably persistent and prevalent--regardless of your HDL.

We've seen small LDL even with HDLs in the 90's! I call small LDL the "cockroach" of lipids. If you think you have it, you probably do. Getting rid of small LDL requires a specific bug killer. (Track Your Plaque Members: Read Dr. Tara Dall's interview on small LDL.)

Don't let anybody blow off your request for lipoprotein testing just because your HDL is high. That's just not acceptable. Loads can be wrong even with a favorable HDL.

Are you the exception?


I read about 40 heart scans this morning. In the stack was a 41-year old man with a heart scan score of 841.

That's terribly high for anyone, let alone a 41-year old person. He's lucky to find out about this before catastrophe strikes.

People like this worry me. In general, we advise men to consider a heart scan age 40 and older; women 50 and older. If there's anything exceptional about your family history or your own history, then you might notch these numbers down another 5-10 years. For instance, if your Dad had a heart attack at age 43, you might consider a scan at age 35. Or, if you've had diabetes for several years and you're a 42-year old woman, you might think about a scan. (Men tend to develop measurable plaque by heart scans 10 years before women.)

There are no hard and fast rules. It's unusual for a male to have a score >0 before age 40. Likewise, it's very uncommon for a woman to have a score >0 before age 50. But there are occasional exceptions--but they can be very important exceptions.

Our 41-year old man with the score of 841, for instance, probably had a high score since his mid-30s. I've seen several women without any obvious risk factors with scores in the several hundred range in their early 40s.

My rule: When in doubt, opt for safety. Every day, I still read about people in their 30s, 40s, and 50s dying of heart attacks. It shouldn't happen.

When in doubt, get the heart scan. The most you'll lose is the cost of the scan and a modest exposure to radiation. If your score is zero, you know you're safe for the next 5 or more years. But if you have an exceptional score at a young age, take preventive action.

Self-empowerment in health: The new wave in health care

Track Your Plaque is just one facet of the broad and powerful emerging wave of self-empowerment in health.

Hospitals, drug and device manufacturers, and the medical establishment don't like this idea. People managing their own health? That's ridiculous! Dangerous! But mostly unprofitable.

Self-empowerment means having easy access to simple, safe, and inexpensive diagnostic tests like heart scans, carotid scans, bone densitometry (for osteoporosis), cholesterol tests, abdominal ultrasound, even brain scans (e.g., CT or MRI) for people with a family history of brain aneurysm.

Opponents of this idea worry about the "false-positives" that come about with broad testing, i.e, detection of abnormalities that are artifactual. Our experience is that false-positives are only an occasional problem with any test. Instead, we find that most people have many true-positives. In CT heart scanning, for example, we find many unsuspected enlarged aortas (potential future aneurysms), valve disorders, and aortic calcium. These are all important in a preventive program. Unfortunately, your doctor's definition of false-positive often means that no corrective procedure or operation is required.

Other evidence that self-empowerment in health is growing:

--The nutritional supplement movement. What better example of power in managing your own health is there than the fabulous array of nutritional supplements available?

--Medications moving to over-the-counter status. Gradually, more and more medications are trickling into availability for you to obtain without a doctor's prescription.

--What I call "retail imaging", i.e. screening ultrasound, heart scans, full body scans, etc. that are available in most states without a doctor's order.

--The Internet. The rapidity and depth of information available on the Internet today is mind-boggling. It will fuel the self-empowerment movement by providing sophisticated information to the health care consumer previously available only through your physician.

--High-deductible health insurance plans. If health care consumers will bear more and more of the costs of health care, they will seize greater responsibility for early identification and prevention to minimize long-term costs.

There are more. But the movement is powerful and broad--and unstoppable. Let the establishment with vested interests in preserving the status quo fuss and complain, just like horse and buggy manufacturers did in the early 1900's when the autmobile came along.

Who cares about triglycerides?

Walter's triglycerides were 231 mg. His LDL cholesterol was "favorable" at 111 mg, HDL likewise at 49 mg.

"Everything looks good," his doctor declared.

"Do you think the triglycerides are okay, too?" Walter asked.

"Well, the guidelines do say that triglycerides should be less than 150, but I believe you're close enough. Anyway, triglycerides don't really cause heart disease."


When I met Walter, I made several comments. First of all, in light of his heart scan score of 713, none of his numbers--HDL, LDL, or triglycerides-- were acceptable. But the triglycerides were glaringly and terribly too high.

Why? What exactly are triglycerides?

Triglycerides are a basic fat particle that, though they do not cause heart disease directly, trigger the formation of an array of abnormal lipoprotein particles in the blood that are among the most potent causes of heart disease known.

These abnormal lipoprotein particles include small LDL, VLDL, and IDL (intermediate-density lipoprotein--a really bad pattern). Excess triglycerides also cause HDL to drop. They also cause a distortion of HDL structure, causing the particles to become abnormally small. Small HDL is also useless HDL, unable to provide the protection that HDL is designed to do.

So Walter's elevated triglycerides are, in reality, a substantial red flag for an entire panel of abnormal particles that contribute to the growth of his coronary plaque.

So, if you get this kind of commentary on your triglycerides, ask for another opinion. (Track Your Plaque Members: Also see Triglycerides: Mother of meddlesome particles at http://www.cureality.com/library/fl_dp002triglycerides.asp.)

Total cholesterol and heart scans

Andy was fearful of heart disease in his life. At age 52, he'd already had four CT heart scans--one each year on or near his birthday.

Yet, when I looked at Andy's scans, his scores had been increasing 20-24% per year. Each and every score was greater by 20% or more over the previous.

So I asked Andy what steps he had taken to stop this relentless progression. "Well, I've always been real health conscious. But ever since my first scan, I really started sticking to a healthy diet, exercising nearly every day, and I take a bunch of supplements."

"What did your doctor advise?" I asked.

"Well, Dr. ---- said that nothing needed to be done, since my total cholesterol was always below 200."



Men's Health magazine's fabulous story about the folly of using total cholesterol to gauge heart disease risk.




Aaaauuuggghhh!! Wrong!

This man was, in fact, at rapidly escalating risk for heart attack. This rate of growth simply can't continue forever without igniting this bomb.

A total cholesterol below 200 is meaningless, as Andy's increasing coronary plaque proved. For instance, you can have a total cholesterol of 165 mg but with an HDL cholesterol of 27 mg. This would constitute very high risk for heart disease despite the low total cholesterol. The low HDL pattern is among the most common reasons for a misleading total cholesterol. Small LDL, high triglycerides, and lipoprotein (a) are other frequent reasons.

Andy, run the other way! Do not heed this doctor's advice! You need a solid answer to the question: Why exactly do I have coronary plaque in the first place?

Then, agree on a treatment program that corrects your specific causes.

Cardiologists out of touch

This weekend, I'm fulfilling some responsiblities I have every so often to some of the local hospitals. It gives me a chance to interact with many of my colleagues who are likewise "on call" for the weekend.

I tried to strike up several conversations with colleagues about how they were managing heart disease prevention. I received blank stares, puzzled looks, indifference. One colleague declared that 80 mg of Lipitor is all you need to know.

These same colleagues are the ones scrambling for the heart attack patients in the emergency room, climbing over one another for consultation in the hospital for patients with chest pain and heart failure. They're consumed with expanding the range of procedures they can perform.

Carotid stenting is hot. So is stenting of the leg arteries. Defibrillators have been a financial bonanza. Opportunities abound on how to add these procedures to a cardiologist's abilities.

But heart disease prevention? How about heart disease reversal?

Frankly, I'm embarassed by my colleagues' lack of interest. Imagine we had a cure for breast cancer--not a palliative therapy that just slows the disease down or prolongs life, but actually cures it once and for all. I would hope that all physicians and oncologists would learn how to accomplish this. What if instead they focused on learning new ways to remove breasts, administer new toxic chemotherapies, etc. but ignored the whole idea of cure?

This is what is happening with coronary plaque reversal. The answer is right in front of them, but the vast majority (99%) of cardiologists choose to ignore it. After all, prevention and reversal simply don't pay the bills.

That means that, in 2006, you simply cannot rely on your cardiologist to counsel you on how to achieve regression or reversal of coronary plaque. How about your internist, family physician, or primary care doctor? Well, they're busy doing pneumovax injections, Pap smears, managing knee and hip arthritis, low back pain, diarrhea, headaches, sinus infections and . . yes, dabbling in heart disease prevention.

And, for the most part, doing a miserable job of it. What you generally get echoes the drug manufacturers pitch: Take a statin drug, cut the fat in your diet.

Until the majority of doctors catch on, you're going to have to rely on sources like the Track Your Plaque program for better information.
