Almonds are the new wheat

Once you eliminate this genetically-altered Frankengrain called modern wheat, the diet should center around vegetables, nuts, healthy oils like olive and coconut, fish, meats, cheese, olives, avocados and other real whole foods. This is, in fact, the diet that I have advocated in my heart disease prevention practice, as well as my online program for prevention and reversal of heart disease.

But what if you'd like a piece of cheesecake or a nice slice of dessert bread---but you don't want to gain two pounds, spend 48 hours in the bathroom suffering with diarrhea and cramps, 3 weeks of joint pains and leg swelling, wade through mental "fog," anxiety, and rage just because you had that momentary indulgence---as you would with wheat?

That's why I've been focusing on recipes that allow you to have something familiar, e.g., chocolate coconut bread or biscotti, but using ingredients that will not generate the metabolic contortions triggered by wheat.

On perusing these recipes, you will notice that there are recurring ingredient themes. Many of the same ingredients pop up time and again. Among the most frequent, versatile, user-friendly, and tasty: Almonds.

You can use almonds as ground whole almonds, ground blanched almonds for a finer texture, ground roasted almonds, almond butter (though, for maximum health benefits, I prefer the ground whole almonds). Ground almonds allow you to recreate muffins, breads, scones, pizza crust, pie crust, biscotti, and cookies with health benefits that exceed that of whole wheat---but with none of the downside: no weight gain, no high blood sugar, no triggering of small LDL particles (#1 cause of heart disease in the U.S.), no accumulation of visceral fat, no appetite stimulation.

In short, you just have your chocolate almond biscotti or mocha cupcake and enjoy it, no health price to pay. So I call almonds the new wheat, except better.

Being regular is dangerous to your health

No, I'm not referring to your daily morning ritual in the bathroom. I'm talking about heart rate.

Counterintuitively, a perfectly regular heart rate is a marker of poor health. People with perfect regularity of heart rate have more heart attacks, for instance.

Regularity of heart rate occurs more commonly in people with hypertension and other metabolic derangements, and it signals increased risk for both heart attack and death. A perfectly regular heart rate, i.e., no variation in the time interval from beat to beat, suggests that the parasympathetic nervous system, the component of automatic ("autonomic") nervous system control that is associated with the relaxation response, feelings of well-being, quiet, and relaxation, is weak. It also means that the opposing sympathetic nervous sytem that regulates the "fight or flight," adrenaline-like response is allowed to be dominant. Dominance of the sympathetic over the parasympathetic system generates regularity of heart rate. Heart rate also tends to be faster, e.g., 85 beats per minutes rather than 55 or 60 beats per minute. So perfect regularity, as well as increased rate, is undesirable.

What we want is irregularity of heart rate. But not irregularity that occurs chaotically with no rhyme or reason. More precisely, we want variability in heart rate. And we want variability to occur in synchrony with breathing, i.e., the respiratory cycle.

The ideal response is:

1) increase in heart rate with inspiration

2) decrease in heart rate with expiration.

Heart rate in healthy people typically varies 15-20 beats per minute within the respiratory cycle, e.g., 60 bpm at end-exhalation, 80 bpm at end-inspiration.

Restoration of increased heart rate variability is associated with reduced blood pressure, reduced blood sugars (HbA1c), reduced inflammatory markers and cortisol (associated with stress), even an increase in DHEA levels. Feelings of well-being and calm also develop.

Among the strategies to consider to restore heightened heart rate variability and slowed heart rate include:

--Omega-3 fatty acid supplementation
--Exercise
--Weight loss
--Deep breathing exercises
--Meditation, prayer, and biofeedback

For our Track Your Plaque purposes, we are folding in the HeartMath strategies, i.e., use of a heart rate monitor that calculates heart rate variability in the context of respiratory cycle. If you've not already done so, take a look at the two Special Reports devoted to this topic on the Track Your Plaque website.

You mean weight loss is hazardous to your health?

In my last Heart Scan Blog post, What is this wacky thing called weight loss?, I discussed how weight loss is associated with distortions in cholesterol and blood sugar values that can be very confusing, often leading your doctor to wrongly and unnecessarily prescribe drugs--since he/she likely rarely sees weight loss.

Blog reader, Donald K., posted his enlightening story:

I experienced this very thing.

After losing serious weight from the eliminating wheat, processed, and sugary foods (1 year in total) I lost 130 pounds. When I was nearly finished I went to see my doctor. He wanted to put me on statins. I explained to him how the data does not support application to me (no evidence of heart disease) and I got the mantra about standards of practice, etc, etc. I held my ground and decided I am much happier eating dairy, eggs, grass fed beef, wild caught fish, and as much raw foods (nuts, veggies, fruits) as my body desires to treat my health parameters.

Maintaining weight, it is easy. My BMI (23 down from 40) has remained constant for a few months now. You are right: metabolic processes definitely change. I no longer have sensations of glucose fluctuations or an uncontrolled appetite. I can only imagine the improved hormone regulation and metabolic communication going on inside my body.

The symptoms from obesity, all gone. Goodbye sleep apnea, hypertension, hemorrhoids, arrhythmias, gastroinestinal disruptions, smelly body, chaffing thighs, and others not mentioned. The positive effects are just as dramatic, but I don’t want to ramble on.

Weight loss? What is it? Getting your life back!


Brace yourself: If you are following the nutrition advice posted here and in the Track Your Plaque program, or the discussion I've initiated in Wheat Belly, then you may find yourself in the very same health predicament as Donald. Arm yourself to protect yourself against the drug-wielding ways of doctors. No, weight loss to achieve ideal weight is definitely not bad for health. But your doctor's misinterpretation of its effects can be!

What is this wacky thing called "weight loss"?

I've discussed this before, but it has proven such an (encouragingly!) frequent issue that I thought it was worth discussing once again.

What happens when you lose weight?

The process of weight loss is characterized by multiple shifts in metabolic patterns that can be confusing. To the uninitiated eye, weight loss can look like a disastrous distortion in metabolism. The naive doctor on seeing your lab values, for instance, might insist you take a statin drug, a fibrate like Tricor (to reduce triglycerides or increase HDL), or simply berate you for your bad health habits--when it's actually a good thing you've accomplished.

So when you lose weight, say, 30 pounds in 3 months, what have you accomplished?

Energy stored as fat, especially from visceral fat stores, is mobilized into the bloodstream. It floods the bloodstream as fatty acids and triglycerides. These fatty acids and triglycerides don't occur in isolation, but interact with other particles and metabolic patterns. The resulting blood patterns include:

--Increased triglycerides--An increase in triglycerides, for instance, from 90 mg/dl to 200 mg/dl in the midst of weight loss is common.

--Reduced HDL--The flood of triglycerides leads to increased degradation of HDL, thus a drop. A drop in HDL from, say, 40 mg/dl to 27 mg/dl--very frightening to people--is exceptionally common.

--Increased blood sugar--The flood of fatty acids and triglycerides results in insulin resistance, leading to higher blood sugars. It is not uncommon for someone with pre-diabetes to develop diabetic-range blood sugars, or a non-diabetic to show pre-diabetic blood sugars.

--Increased small LDL particles--Though small LDL is highly variable during weight loss. When it does happen, it's probably from the interaction of VLDL (triglycerides) with LDL particles and the reaction that overloads LDL particles with triglycerides and conversion to small LDL particles.

So why don't doctors often recognize these patterns when a patient loses weight? Because they rarely see it. Most of my colleagues are accustomed to having patients come back with weight gain, getting heavier and heavier each time. Lose weight? Impossible! So they just don't recognize weight loss effects when they see it. As followers of The Heart Scan Blog know, a frequent conversation around here is "Am I too skinny?" or "How do I stop losing weight?"

The solution: Be patient. Be patient and wait about two months after a weight plateau has been achieved. That's when the numbers "settle down" and you see marked drops in triglycerides, increases in HDL, drops in blood sugar, reductions in small LDL.

As with many things, it's all about timing.

Why small LDL particles are the #1 cause of heart disease in the US

Ask your doctor: What is the #1 cause of heart disease in the US?

Let's put aside smoking, since it is an eminently modifiable risk and none of those crazies read this blog anyway. What will your doctor say? Most like he or she will respond:

High cholesterol or high LDL cholesterol

Too much saturated fat

Obesity

Pfizer, Merck, AstraZeneca and their kind would be overjoyed to know that they can add your doctor to their eager following.

I'd tell you something different. I would tell you that small LDL particles are, by far and away, the #1 cause for heart disease. I base this claim on several observations:

--Having run over 10,000 lipoprotein panels (mostly NMR) over the past 15 years, it is a rare person who does not have a moderate, if not severe, excess of small LDL particles. 50%, 70%, even 90% or more small LDL particles are not rare. Over the course of a year, the only people who show no small LDL particles are slender, athletic, pre-menopausal females.

--In studies in which lipoproteins have been quantified in people with coronary disease, small LDL particles dominate, just as they do in my office. Here's a 2006 review.

--Small LDL is largely the province of people who consume carbohydrates, such as the American population instructed to "cut fat and eat more healthy whole grains." Conventional diet advice has therefore triggered an expllosion in small LDL particles.

--When fasting triglycerides exceed 60 mg/dl, small LDL particles increase as a proportion of total LDL particles. This includes the majority of the US population. (This ignores postprandial, or after-eating, triglycerides, which also contribute to small LDL formation.)

If you were to read the data, however, you might conclude that small LDL affects a minority of people. This is because in most studies small LDL categorize it as either "pattern B," meaning exceeding some arbitrary threshold of percentage of small LDL particles, versus "pattern A," meaning falling below that same arbitrary threshold.

Problem: There is no consensus on what percentage of small LDL particles should mark the cutoff between pattern A vs. pattern B. In many studies, for instance, people with 50% small LDL particles are called "pattern A."

If, instead, we were to set the bar lower to identify this highly atherogenic (atherosclerotic plaque-causing) particle at, say, 20-30% of total, then the number or percentage of people with "pattern B" small LDL particles would go much higher.

I see this play out in my office and in the online program, Track Your Plaque, every day: At the start eating a low-fat, grain-filled diet with lots of visceral fat ("wheat belly") to start, they add back fat and cut out all wheat and limit carbohydrates. Small LDL particles plummet

Even moore from Jimmy Moore

The ubiquitous and irrepressible Jimmy Moore posted even more commentary about the Wheat Belly phenomenon here, what he calls "The Wheat Belly Bonanza."

Is low-carb really, at its core, little more than elimination of wheat? Sure, corn, rice, and sugar exert deleterious effects. But the dominant effect--by far--is the elimination of wheat. So is the low-carb movement really, at its core, a wheat-elimination movement?

Food (non-wheat-containing, of course) for thought.

Heart Scans: An Interview with Jimmy Moore

My friend, Jimmy Moore, of The Livin' La Vida Low Carb Show, posted this video of an interview I did with him.

I provide some background on how heart scanning came about and how it led to the creation of the Track Your Plaque program.

It reminds me how far we've come over the 8 years since the program got started. From its modest start as just an information resource to help people understand their heart scan score, to a comprehensive program that helps followers gain incredible control over coronary plaque and coronary risk that has now expanded to over 30 countries. High-tech heart procedures still dominate public consciousness, but the tremendous power of real heart disease prevention efforts are gaining more and more attention as each day passes.

Wheat Belly #5 on New York Times Bestseller list!

The New York Times just released its bestseller list due for release September 18th, 2011 . . . .

Wheat Belly is #5!! (That darned Jane Fonda woman elbowed me out for the #4 spot!

Interview with Jimmy Moore of Livin' La Vida Low-Carb

Here's my podcast interview with Jimmy Moore, host of the Livin' La Vida Low-Carb Show. (If you want to fast forward to the interview, go to time marker 41:20 on the slidebar.)



In the podcast, I talk about how the Track Your Plaque program and its focus on lipoprotein testing, along with the need to reverse the incredible epidemic of diabetes and pre-diabetes, led to elimination of all wheat from the diet and the book, Wheat Belly.

An open letter to the Grain Foods Foundation

Readers: Please feel free to reproduce and disseminate this letter any way you see fit.

Ms. Reynolds:

I am writing in response to the press release from the Grain Foods Foundation that describes your effort to "discredit" the assertions made in my book, Wheat Belly: Lose the wheat, lose the weight and find your path back to health. I'd like to address several of the criticisms of the book made in the release:

" . . . the author relies on anecdotal observations rather than scientific studies."
While I do indeed have a large anecdotal experience removing wheat in thousands of people, witnessing incredible and unprecedented weight loss and health benefits, I also draw from the experiences already documented in clinical studies. Several hundred of these studies are cited in the book (of the thousands available) and listed in the Reference section over 16 pages. These are studies that document the neurologic impairment unique to wheat, including cerebellar ataxia and dementia; heart disease via provocation of the small LDL pattern; visceral fat accumulation and all its attendant health consequences; the process of glycation via amylopectin A of wheat that leads to cataracts, diabetes, and arthritis; among others. There are, in fact, a wealth of studies documenting the adverse, often crippling, effects of wheat consumption in humans and I draw from these published studies.


"Wheat elimination 'means missing out on a wealth of essential nutrients.'"
This is true--if the calories of wheat are replaced with candy, soft drinks, and fast food. But if lost wheat calories are replaced by healthy foods like vegetables, nuts, healthy oils, meats, eggs, cheese, avocados, and olives, then there is no nutrient deficiency that develops with elimination of wheat. There is no deficiency of any vitamin, including thiamine, folate, B12, iron, and B6; no mineral, including selenium, magnesium, and zinc; no polyphenol, flavonoid, or antioxidant; no lack of fiber. With regards to fiber, please note that the original studies documenting the health benefits of high fiber intake were fibers from vegetables, fruits, and nuts, not wheat or grains.

People with celiac disease do indeed experience deficiencies of multiple vitamins and minerals after they eliminate all wheat and gluten from the diet. But this is not due to a diet lacking valuable nutrients, but from the incomplete healing of the gastrointestinal tract (such as the lining of the duodenum and proximal jejunum). In these people, the destructive effects of wheat are so overpowering that, unfortunately, some people never heal completely. These people do indeed require vitamin and mineral supplementation, as well as probiotics and pancreatic enzyme supplementation.


I pose several questions to you and your organization:

Why is the high-glycemic index of wheat products ignored?
Due to the unique properties of amylopectin A, two slices of whole wheat bread increase blood sugar higher than many candy bars. High blood glucose leads to the process of glycation that, in turn, causes arthritis (cartilage glycation), cataracts (lens protein glycation), diabetes (glycotoxicity of pancreatic beta cells), hepatic de novo lipogenesis that increases triglycerides and, thereby, increases expression of atherogenic (heart disease-causing) small LDL particles, leading to heart attacks. Repetitive high blood sugars that develop from a grain-rich diet are, in my view, very destructive and lead to weight gain (specifically visceral fat), insulin resistance, leptin resistance (leading to obesity), and many of the health struggles Americans now experience.

How do you account for the psychologic and neurologic effects of the wheat protein, gliadin?
Wheat gliadin has been associated with cerebellar ataxia, peripheral neuropathy, gluten encephalopathy (dementia), behavioral outbursts in children with ADHD and autism, and paranoid delusions and auditory hallucinations in people with schizophrenia, severe and incapacitating effects for people suffering from these conditions.

How do you explain the quadrupling of celiac disease over the last 50 years and its doubling over the last 20 years?
I submit to you that, while this is indeed my speculation, it is the changes in genetic code and, thereby, antigenic profile, of the high-yield semi-dwarf wheat cultivars now on the market that account for the marked increase in celiac potential nationwide. As you know, "hybridization" techniques, including chemical mutagenesis to induce selective mutations, leads to development of unique strains that are not subject to animal or human safety testing--they are just brought to market and sold.

Why does the wheat industry continue to call chemical mutagenesis, gamma irradiation, and x-ray irradiation "traditional breeding techniques" that you distinguish from genetic engineering? Chemical mutagenesis using the toxic mutagen, sodium azide, of course, is the method used to generate BASF's Clearfield herbicide-resistant wheat strain. These methods are being used on a wide scale to generate unique genetic strains that are, without question from the FDA or USDA, assumed to be safe for human consumption.

In short, my view on the situation is that the U.S. government, with its repeated advice to "eat more healthy whole grains," transmitted via vehicles like the USDA Food Pyramid and Food Plate, coupled with the extensive genetic transformations of the wheat plant introduced by agricultural geneticists, underlie an incredible deterioration in American health. I propose that you and your organization, as well as the wheat industry and its supporters, are at risk for legal liability on a scale not seen since the tobacco industry was brought to task to pay for the countless millions who died at their product's hands.

I would be happy and willing to talk to you personally. I would also welcome the opportunity to debate you or any of your experts in a public forum.

Is it mainstream or alternative?

A question I get about once a week: "Is your program a kind of alternative medicine?"

Our program for control and reversal of coronary plaque using CT heart scans applies an eclectic panel of tools to achieve its goals. We use high-tech methods like lipoprotein analysis and CT heart scans; nutritional supplements like fish oil, vitamin D, and l-arginine; diet strategies and "functional foods" (using foods as a therapeutic tool); and conventional medication.

I don't consider this approach "alternative" in the sense that it uses unmeasurable or spiritual strategies. But I don't consider it mainstream, either, since current mainstream practice of heart disease prevention is far less rigorous with far less satisfactory results.

I think I can sum up the Track Your Plaque approach by saying that we use tools that work. Our measure of success is whether or not your heart scan score is stopped or reduced--that's hard to fudge. You can call it what you will, but I call it the best program for heart disease prevention I know of, alternative or mainstream.

Want to see someone turn diabetic?

If you want to witness the transformation of someone into a pre-diabetic or diabetic, put them on a low fat diet.

Dr. Dean Ornish's program, detailed in his books, Dr. Dean Ornish's Program for Reversal of Heart Disease and Eat More, Weigh Less , are woefully outdated in 2006. Yet the low fat notion continues to show up in the consciousness of people I talk to about heart disease reversal.

"I'm already on a low fat diet. Do you think my heart scan score has reversed?"

Highly unlikely. What Dr. Ornish (as a non-cardiologist, by the way) failed to recognize is that what he did manage to reverse in a small number of people is something called "endothelial dysfunction", but he did not reverse or shrink coronary plaque.

Given the limitations of technology when the Ornish concept got its start, it appeared as if reversal was obtained. In reality, all his approach accomplished was a relaxation in tone of abnormally constricted arteries, thus giving the appearance of reversal. Increased artery tone, or endothelial dysfunction, is extremely common when atherosclerotic plaque is present.

Any cardiologist will tell you that there are many ways to reverse endothelial dysfunction: exercise, weight loss, cholesterol drugs, drugs for high blood pressure, fish oil, hormonal therapy, vitamin C, l-arginine, etc. There is nothing special about a low fat diet.

In fact, Track Your Plaque followers will recognize that a low fat diet is, in fact, potentially harmful, particularly when low HDL or small LDL is part of your pattern.

Let's bury the outdated ideas of the Ornish low fat diet once and for all. It doesn't work. All it may do is confuse you and set you back from your real coronary plaque reversal program.

Inulin: A fiber for weight loss

Here's an interesting product that seems to be gaining some popularity for weight loss: Inulin.

Not to be confused with "insulin", with which it is completely unrelated, inulin is a naturally-occurring plant fiber. It's found in broccoli, asparagus, celery, etc. Like beta-glucan from oats or pectin, inulin is a so-called soluble fiber, a fiber that assumes a gel-like consistency when exposed to water.

Inulin has the effect of increasing satiety, or the sensation of fullness. This cuts your craving for foods. I've tried it recently and I prefer it over glucomannan, another soluble fiber for satiety.

The people at Stonyfield Farms have been adding inulin to their yogurts from some time. The nutritionist at the company tells me that there's 2-3 grams of inulin per 6 ounce container of their yogurt.

You can also find inulin as a supplement that you can add to foods, available from some health food stores and online supplement companies. I came across a neat product called Fiber Choice that's now being distributed widely throughout the U.S. I tried their Weight Management version. It was a delicous strawberry taste. The label says take two chewable tablets twice a day, but I found that two tablets three times a day somewhat better. It's best taken around 30-60 minutes prior to each meal and it causes you to be fuller with less food. One caution: It'll cause loads of gas, especially in the beginning. For that reason, you might try starting with a smaller dose, or start on the weekends when you have the option of some privacy!

More info on the Fiber Choice product can be found at their website, http://www.fiberchoice.com.

Disclaimer: I have no relationship with the manufacturer of this product. I'm simply passing on some thoughts on my experience with this interesting possibility for weight loss.

Will you recognize the truth when you see it?

Do you ever wonder that, if the truth were given to you, that you'd recognize it as such? Or would you dismiss it as just another bunch of nonsense?

After all, you and I live in the Information Age. It means that we have access to mountains of information like never before in human history. But it also means that the truth is often drowned out by an avalanche of mis-truths, sales pitches and marketing, and just plain nonsense.

This struck me the other day when I was talking to a patient.

64 years old with a high heart scan score placing her at significant risk, she looked confused. I'd just described the multitude of causes of coronary plaque that we'd uncovered. The heart scan alone had been a shocker.

"I don't understand. My doctor told me that I had nothing to worry about. I've known him for years and he knows me really well. He did a stress test. That was fine. I don't get all this other stuff you're telling me--lipoprotein whatever..."

Despite my efforts to help her gain an understanding of our intensive approach, she just became increasingly more frustrated. "I just don't think I can do this."

That's the last I've heard from her. As far as I know, she's returned to the comfort of her family doctor who has reassured her over the years. And perhaps there's some good in that. But I do fear for the day when, unexpectedly, she suffers some catastrophe that we told her was coming sooner or later unless real preventive efforts were started.

You could say that she failed to recognize the truth when it was given to her-- boldly, unadorned, and with far greater scientific certainty than the casual reassurances she was accustomed to. But, unfortunately, that's all that some people want.

Don't neglect the basics in your heart disease reversal program

Carl loved new ideas and novel approaches. You could tell by the sheer number of nutritional supplements he took. His list had grown to 18 different supplements over the past two years.

Carl came to me for coronary plaque regression. Lipoprotein analysis did uncover several previously unsuspected abnormalties, most notably small LDL particles and lipoprotein(a). In addition, Carl's LDL cholesterol ranged between 111 mg-156 mg and he was clearly hypertensive, with systolic blood pressures consistently around 150-160. (Recall that people with Lp(a) are more prone to hypertension.)

Carl was more than willing to have his lipoprotein(a) reduced. We did so with niacin and testosterone and the level dropped to near zero. Likewise, we corrected his small LDL pattern with niacin, fish oil, and a reduction in processed carbohydrates.

But Carl really resisted doing much about his LDL cholesterol and high blood pressure. I got the sense that these "boring" issues simply didn't interest him. After all, LDL cholesterol and blood pressure were the stuff of TV commercials and the popular conversation propagated by drug companies.

Carl's follow-up heart scan, however, finally persuaded him: a 24% increase in one year, likely due to the neglect of the basic issues.

I liken Carl's case to being like the teenager with a new car who polishes the paint to a bright finish, puts new wheels and tires on it, spruces up the interior with various doodads--but then fails to change the oil. Sometimes it's the most basic issues that can diminish your success.

Issues like LDL cholesterol and high blood pressure aren't the most glamorous, but they do count in your coronary plaque control program.

Is your doctor a hospital employee?

There's a disturbing trend that's growing--silently but rapidly.

In Milwaukee, three hospital systems compete for the local health care dollar. To gain more control over revenues and the routing of patients, the hospitals are aggressively hiring physicians to work for them. I've witnessed many of my cardiology colleagues, primary care doctors, and a substantial number of procedural specialists enticed by the offers made by hospital employers.

This phenomenon is not unique to Milwaukee but is being used in many, perhaps most, major cities in the U.S.

This means that physicians are employees of the hospital. That way, employee-physicians are obliged to use only the hospital system that employs them. In the old days, your doctor could use any hospital he/she desired, depending on the quality, location, facilities, etc. Now, many physician-employees are given no choice but to use the hospital that pays their salary.

That by itself is not necessarily bad. But combine salary with incentives for bringing in patients for hospitalization and procedures--that the rub. In other words, physician-employees are incentivized to generate more revenue for the system, just as employees in many other industries.

If you're a salesman for an insurance company, your job is to bring in more business. If you're a worker on an auto production line, you're expected to meet certain quotas. These same principles are now being applied to many physicians.

How does this affect you? Well, if your physician--especially procedure-driven specialists like cardiologists, general surgeons, orthopedists, etc.--is a hospital employee, BEWARE! Do you really need that procedure, or is your doctor suggesting you have a procedure because it will add to his track record?

Prevention? In this model of health care, why bother? It certainly doesn't pay for a hospital to keep you well. Then why should your physician-employee?

Be careful who you're dealing with. If your physician is a hospital-employee, don't bet on getting preventive care. It's more likely you're that just a future source of revenue when it's time for your bypass operation, hip replacement, carotid endarterectomy, etc.

What more powerful argument is there for increased self-empowerment and information for health care consumers?

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 implantable cardioverter-defibrillators (ICDs) were substantially broadened [emphasis ours] to include most patients with a left ventricular ejection fraction (EF) of 35% or less. This change translates into a 2- to 3-fold increase in the number of Medicare beneficiariries eligible for ICDs."

Ka-ching!!! Hear the money piling up in the bank?

The device manufacturers are constantly churning data and lobbying for reimbursement to expand the use of their devices to more and more people. Defibrillators in particularly are generally a $25,000 to $50,000 opportunity for the device manufacturer alone, not counting the costs incurred at the hospital for implantation.

Beware. As reimbursement for stents and other procedures diminishes, expect a sudden "demand" for more and more people to get implantable defibrillators. Better yet, stay away from the whole issue by preventing your heart attack.

Get a heart scan--but then don't delay taking action!

I just came from one of the local hospitals after having performed a heart catheterization on a patient I met earlier this week.

Jack had gotten a heart scan a year ago with a score of 246, placing him in the 76th percentile. The "event" rate with this percentile rank is around 3% per year--not very high but enough to pose risk over a long period.

Jack chose to ignore his score. After all, the pressures of work at the University, maintaining his home and yard, etc. consumed all his energies. He came to my office--now one year after his scan--and told me about the chest pressure he was getting. Initially, his chest pains occurred with extended walking. In the past week, however, Jack was experiencing chest pressure with just walking 30 feet.

This pattern of increasing symptoms is called "accelerated angina", meaning that Jack was rapidly heading towards a heart attack. So I advised a heart catheterization in near future.

Jack's catheterization showed extensive plaque including a 50% blockage in the mainstem artery and 90% in the artery to the front of the heart (left anterior descending artery). Jack is going to have a bypass operation tomorrow.

What if Jack hadn't ignored his heart scan from a year ago? Well, I'd be very confident in saying that he would not be undergoing bypass surgery tomorrow.

The lesson: Don't dilly-dally on taking action to keep your plaque from growing. While it's not an emergency, it can easily become one if you choose to ignore your scan.

Feel that nudge in your back?

You feel that nudge in your back? That's your local hospitals competing for your bypass surgery business.

Just this morning while watching a morning news show, I saw three advertisements for hospital bypass surgery programs. One ad featured a man in his 50s telling his story:"The cardiologist determined immediately that I needed a triple bypass operation. My family and I are very grateful to _____ hospital!"

In what other field is failure celebrated so prominently? When I see these ads, I hear "My doctors failed to provide early detection and then prevent what became a life-threatening condition, even though heart disease is a chronic process that requires decades to develop." What if our man said instead,"I had a heart scan and my score was high. So I was shown why I had so much plaque. They then showed me how to control and even reduce the amount of plaque I had. I'm living safely and symptom-free without need for surgery or procedures."

Of course, the hospital is out $60,000-100,000 for the surgery. How else could they afford ad campaigns costing several million dollars a year? See these advertisements for what they are: Marketing generated by profit-seeking businesses competing for your dollars--lots of them.
"Your heart scan score means nothing"

"Your heart scan score means nothing"

Charles was visibly confused.

He'd gotten his CT heart scan after hearing one of the local scan center's ads on the radio. His score 2773, obviously in the 99th percentile for any age.

"Do you think the score means anything? My primary doctor said that it was meaningless because it was all in the deep wall of the artery. He said that it has nothing to do with risk for heart attack. As long as I feel good, he says don't do anything."

What exactly did his doctor mean, in the "deep wall of the artery"?

What the doctor is referring to is the fact that some people with a long history (many years) of diabetes or kidney failure (also for many years) tend to develop calcium deposits in the media, or muscular layer of arteries. The media is the tissue thin layer just below the intima, the most inner layer of arteries that we usually associate with atherosclerotic plaque and the layer that is most prone to calcium accumulation that we score on heart scans.

Aging, generally into your late 70s, 80s, and onwards, also increases the likelihood of medial calcification. Lastly, longstanding deficiency of vitamin D encourages medial calcification.

Is there any way to distinguish intimal vs medial calcification on a heart scan? No, there is not. Having read many thousands of CT heart scans, I can tell you that there is no practical way in 2007 to tell the difference.

Then how did this doctor "know" that Charles' calcium was "deep walled" or medial? Simple: He didn't. This was yet another example of ignorance based on old thinking. Unfortunately, he did Charles a serious disservice by dismissing his heart scan score that predicted a 25% per year risk for heart attack.

Interestingly, whether calcium is intimal as in atherosclerotic plaque, or medial, both are strongly associated with risk for heart attack. In other words, if calcium is confined to the intima, heart disease risk is present. If calcium is limited to the media, risk is still present.

In all practicality, the only difference we make of the intima vs. media argument (that is, when the distinction has been made by some other means like intracoronary ultrasound, the test that is truly necessary to distinguish the two patterns) is that medial calcification may be more powerfully related to vitamin D deficiency. Thus, someone with heavy medial calcification may require closer attention to maintaining a perfect year-round blood level of 25-OH-vitamin D3. But that's the only practical difference.

    Will maintaining the Vit D level at the optimal range, reverse the media calcium build up?

    Our emerging experience in the Track Your Plaque program suggests that medial calcification may, in fact, be MORE amenable to regression/reversal.

    Dr Davis:
    I am 72.
    I recently had a CTA scan with "no detectable paque"
    I am also aware of recent research which shows evidence of menaquinone both preventing and reversing calcification.
    Is scanning thought to be less sensitive to medial calcification (as opposed to intimal), and at risk of being 'missed'?

    If so would preventive menaquinone be justified in a 'clean' case like mine?
    Thanks, MikeV

    Hi, Mike-
    No, the scan quite reliably detects both intimal and medial calcification. Taking K2 is very optional. How about some traditional, fermented cheese? I do not believe that K2 supplementation would yield substantial heart benefits. However, if bone health is in question, that migyht be a reason.

    Thanks, Doc:
    My cheese score is already fairly high.
    I forgot to mention that I have already been taking fish oil, coQ10,vitamin D3, magnesium etc for some years, so I *heartily* endorse your standard recommendations.
    You perform a great community service.

    The media is the tissue thin layer just below the main fact because is one of the lasted arteries, the most inner layer of arteries that we usually associate with atherosclerotic plaque and this'll be an important discussion at the universities. Absolutely. 23jj
