How important is high blood pressure?


Control of blood pressure is crucial for coronary plaque control and stopping your heart scan score from increasing.

Dr. Mehmet Oz (of Oprah fame and a cardiac transplant surgeon at Columbia University) made graphic point of this on the ABC TV news show, 20/20, last evening on an episode called "Our Bodies: Myths, Lies, and Straight Talk". (See a summary on the ABC News 20/20 website at http://abcnews.go.com/2020/story?id=2109291&page=1)

Although I believe he somewhat overstated the case for hypertension (proclaiming "If you're going to remember one number, if you're going to focus and fixate on one number in your entire health profile, it better be your blood pressure"), he made the point that a blood pressure of 115/75 is what you should have for optimal health.

I couldn't agree more. Unfortunately, the old advice that desirable blood is 140/90 or less is absolutely wrong. At this level, we see flagrant increases in heart scan scores. We also progressive enlargement of the thoracic aorta, the large vessel that leaves the heart and branches to provide the major arteries of the body. Growth of the aorta to an aneurysm is also common at these formerly acceptable blood pressure. (The diameter of your aorta in the chest is an easily obtainable measure on your CT heart scan.)

The blood pressure you need for halting and reversing plaque growth on your heart scan is indeed 115/75 or less. (Not so low, however, that you're lightheaded.) This is the blood pressure that you were meant to have evolutionarily. It's also the blood pressure that helps tremendously in keeping your aorta from enlarging.

Is your doctor in cahoots with the hospital?

I got a call from a doctor about a patient we've seen in past.

"I've got Tricia in the office. She's been having some kind of chest and abdominal pain. I think it's esophageal reflux, but just to be safe I'm sending her to the hospital."

I advised this physician that, given Tricia's low heart scan score, she was unlikely to be having a coronary "event" like heart attack or unstable symptoms. It wasn't impossible, but just highly unlikely.

As the patient was without symptoms at the moment and had driven herself to his office, I offered to perform a stress test immediately. (Though stress tests are of limited usefulness in people without symptoms, they can be useful provocative maneuvers in people with symptoms of uncertain significance.)

The doctor declined. Tricia was, after all, in his office and he was responsible for any decisions despite any objections I voiced. Well, Tricia was directed by her doctor to go to a local hospital, though one with an especially notorious reputation for putting virtually anyone they can get their hands on through as many procedures as possible.

As you might guess, this doctor was closely associated with this hospital. He and his colleagues obtain incentives (or are penalized) if they do not generate revenue-producing procedures for the hospital.

So, guess what? Tricia ended up with several procedures, all of which yielded nothing--except $30,000 in revenues from Tricia's insurance company.

I harp on this deplorable state of affairs because it is utterly, painfully, and shamefully TRUE. Just look at the hospital and you'd better brace yourself for a series of tests that could cost you the equivalent of a nice 3 bedroom home. If they were truly necessary after the failure of preventive and other simple efforts, fine. But, all too often, they are driven by profit motives.

Could I have stopped this somehow from occurring? After all, Tricia was reasonably aware of the way we do things around here. I fear that even this failed to serve Tricia well. But I remain hopeful that, as we build broader awareness of these issues, that more and more people and physicians will stand up and refuse to tolerate the status quo.

Where is the Track Your Plaque program going?

I spend a lot of time worrying about how people can be helped to navigate through this program.

Take, for instance, the man in rural Texas who, while traveling in Dallas, got a heart scan on a whim. His score was 990. When he took the report back to his doctor, he got a smirk--and that's all. When he came to the Track Your Plaque program, he lacked a physician advocate to help him.

Or the woman from Florida who sought opinions from two reputable cardiologists for her heart scan score of 377. Both advised her that she needed a heart catheterization--despite her lack of symptoms, her 5-day-a-week exercise program, and normal stress test. She also lacks a physician advocate who acts on her behalf, helping her achieve success, rather than just churning her for money from hospital procedures.

For people like this and for others, I see the Track Your Plaque program evolving in several directions:

1) An online clinic--You enter and we take your "hand" and lead you step by step through the process, not only at the beginning, but over the months and years. This would help clear up some of the confusion and zigzags that some people experience trying to navigate through the program.

2) Develop physician and non-physician partners--The woman in Florida, for instance, could be referred to a doctor nearby who understands the program and is able to assist her. At present, this is virtually impossible because of the bias towards heart procedures, drugs as the sole treatment for heart disease risk, and the superficial physician-patient relationship. The majority of practicing physicians just don't understand the program despite the fact that it is based on sound clinical and experimental data. But it will in time.

Looking back, we've come a long way. I remember first having patients undergo heart scans 10 years ago. My colleagues laughed or called it "silly". The general public didn't know what they meant.

Now we're talking about how to broadcast the most powerful heart disease prevention program available in the world to a larger audience, but making it easier and more accessible. Mass media like Oprah's two hour-long spots helped, but we need to make the next leap. Not just identifying hidden heart disease to feed the hungry cardiovascular hospital procedure monster, but to educate/inform/empower the public on what to do with the scan once they've had it.

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.

What if your lipoproteins are perfect?



Sandy is a 56-year old woman--fit, slender, physically active, with no bad habits. A retired teacher, she has time to devote to her health. She bikes several days per week, mountain bikes, walks, and takes fitness classes. In short, she's the picture of perfect health.

Her heart scan score was not terribly impressive: 41. However, at her age, this modest score placed her in the 77th percentile. This suggested a heart attack risk of around 2-3% per year.

So we measured Sandy's lipoproteins. They were shockingly normal. In fact, Sandy is among the very rare person with absolutely no small LDL particles. All other patterns were just as favorable, including an HDL in the 80s.

This may seem like good news, but I find it disturbing. People are often initially upset by seeing multiple abnormal lipoprotein patterns. But lipoprotein abnormalities are the tools that we use to gain control over coronary plaque.

So what do we do when there are no abnormalities?

There are several issues to consider:

1) Your heart scan score reflects the sum total of your life up until that point. What if you were 20 lbs heavier 10 years earlier and your lipoproteins were abnormal during that period? Or you smoked until age 45 and quit? As helpful as they are, lipoproteins and related patterns are only a snapshot in time, unlike the heart scan score.

2) You have a vitamin D deficiency. This is unusual as a sole cause of coronary plaque. Much more commonly, it is a co-conspirator.

3) The heart scan is wrong--highly unlikely. Heart scans are actually quite easy, straightforward tests. (The only time this tends to happen is when scoring that appears in the circumflex coronary artery is actually in the nearby mitral valve. This really occurs only when there's very minimal calcium in the valve.)

4) There's a yet unidentified source of risk. Probably very rare but conceivable. For instance, there's an emerging sense that phopholipid patterns may prove to be coronary risks. One clinically available measure that we've not found very useful is phospholipase A2, known by the proprietary name "PLAC" test. (See http://www.plactest.com for more information from the manufacturer/distributor of the test.) But there's probably lots of others that may prove useful in future.

How often does it happen that someone fails to show any identifiable source for their coronary plaque? I can count the number of instances on two fingers--very unusual. (Thank goodness!)

Sandy's case is therefore quite unique. How should we approach her coronary plaque? In this unusual circumstance, lacking a cause, we tend to introduce therapies that may regress plaque independent of any measurable lipoprotein parameters. But that's a whole new conversation.

Fly to India for a bypass operation?


In the June 19, 2006 issue of People Magazine, there's an article called "The Doctor is in . . .INDIA". The report talks about how, with health care costs in the U.S. spiralling out of control, more and more Americans are leaving the country to have their procedure performed.

They tell the story of Mr. Carlo Gislimberti of New Mexico and cite these numbers:

Heart Surgery
Cost in U.S.: $200,000

Cost in India: $10,000


Mr. Gislimberti opted to have his coronary bypass operation in India for cost reasons.

But the People magazine report left out one other option: The Track Your Plaque program: $39.00

Do your part to save ballooning health care costs: Engage in a truly powerful program of heart disease prevention like the Track Your Plaque program. The cost difference is laughably huge. And you won't require a 12-inch chest incision.

Follow conventional guidelines and guess what? You're going to have a heart attack. Follow the American Heart Association diet and you'll have heart disease.

Cut to the chase. The only program that is able to detect, track, and control coronary plaque better than any other process I know of is this program.

Note: I am not proposing that a heart disease prevention program like Track Your Plaque can replace a procedure like coronary bypass when a dangerous situation has developed. The Track Your Plaque program is designed to be implemented in the years before heart surgery is required. That's when you have the greatest control over your fate.

Surprise: Heart scan score reversal

Gene is a jovial, fun-loving railroad worker who didn't take anything too seriously--including his heart scan score of 767.

This score placed Gene solidly in the 99th percentile (in the worst 1%). It came as no surprise to Gene. After all, his father died at age 36 of a heart attack and Gene's brother died at 60 of a heart attack. So Gene took life as it came and long ago decided not to fret about his fate.

But Gene's wife prodded him and prodded him to get the heart scan. That's when I met him.

Of course, Gene had been prescribed Lipitor by his doctor for a somewhat high LDL cholesterol. Our assessment uncovered several additional patterns including lipoprotein (a), small LDL, a pre-diabetic tendency, and a severe deficiency of vitamin D.

At 224 lb and 5 ft 6 inches in height, I felt that Gene was at least 40 lbs overweight.

One year later and with reasonable correction of all his patterns except weight loss and Gene's heart scan score was 590--a reduction of 23%!

Gene was thrilled, as was I. But, frankly, I was also surprised. Dramatic regression of coronary plaque tends to not occur so readily as long as pre-diabetic patterns persist and weight is not controlled.

The lesson: Often the only way to tell if you've achieved control or regression of coronary plaque is to have another heart scan. The tremendous variation in human responses never ceases to amaze me.

Call me when you're having chest pain


I met a patient, Anna, yesterday. She was quite frustrated and frightened.

At age 50, Anna suffered a heart attack and received a stent to her left anterior descending coronary artery. What she found upsetting is that, because several members of her family had suffered heart attacks in their 40s (Dad--heart attack at age 45, paternal uncle--heart attack age 40, and even another uncle with heart attack in his late 20s), she had repeatedly asked her doctor whether she was okay.

She received the usual array of false assurances: "You're feeling fine, right? Then don't worry about it." "Look. Your cholesterol is in the normal range. Even your cholesterol/HDL ratio is fine." "Women don't get heart disease until later in life."

All proved absolutely false. As we talked, Anna exclaimed, "I think what I've been told all along is that we'll take you seriously when you finally have a heart attack!"

She's exactly right. The vast majority of times, heart disease is discovered by accident, usually because of an "event" like heart attack. This is like changing the oil in your car when it finally breaks down--it's too late.

CT heart scan, followed by lipoprotein testing and associated values, then correction of your specific causes. It's that simple.
What's that in your mouth?

What's that in your mouth?




Fat = triglycerides

In other words, eat fat, whether it's saturated, hydrogenated, polyunsaturated, or monounsaturated, and blood levels of triglycerides will go up over the next 6 hours. This remains true if there are carbohydrates in the meal, or if there are NO carbohydrates in the meal. It also remains true if you chronically consume fats.

While fats are the primary determinant of postprandial (after-eating) triglycerides, carbohydrates are the primary determinant of fasting triglycerides.

So, if your triglycerides are high on a fasting cholesterol (lipid) panel, it's most likely because you overconsume carbohydrates.

    "It also remains true if you chronically consume fats."

    my understanding is that it is actually in support of normal metabolic functioning for us to "chronically" eat fat. low carb eating, in my lay-person's opinion, means therefore eating good fats (and i am of the un-pc standpoint that saturated animalfats are a-ok) , not just green veggies alone. low-car and low-fat would be no fun! but that's just my 2 cents.

    I've had two non-fasting cholesterol tests performed in the last year.  My fasting triglycerides are around 40.  My triglycerides three hours after eating a meal with 10g carbs and 59g of fat were 91.  The time prior to that, they were 79 eight hours after breakfast and three hours after lunch (both were high-fat meals).

    Yeah, they go up, but not that much.

    So what about the other side of the equation? Decreasing the absorption rate of fat (or spreading it out over more meals) might not help any. But if you can optimize the deposition of fat where it really belongs, in subcutaneous fat tissue-- that is, if fat is deposited in fat tissue where it belongs until needed, at a rate close to the rate at which new dietary fat is absorbed into the bloodstream-- then there shouldn't be a problem.
    Interventions that raise HDL generally increase adiponectin. Eating less wheat, beer, fructose, or adding in fish oil, niacin, vitamin d, even being born a woman. And they also associate with less wheat belly.

    http://www.springerlink.com/content/dpy09vbc0r8jxnm9/

    -----------------------------------
    Conclusion/interpretation. These data suggest that adiponectin concentrations are determined by intra-abdominal fat mass, with additional independent effects of age and sex. Adiponectin could link intra-abdominal fat with insulin resistance and an atherogenic lipoprotein profile.
    --------------------------------
    Maybe they've got cause and effect reversed here? I read a study in mice that were leptin-deficient. Adding extra adiponectin made the mice fatter. So adiponectin is probably not so much a reaction to deposited fat as it is a promoter, maybe a facilitator of proper fat storage.

    Where Oh Where can I find a Doctor like Doctor Davis in the New Jersey area?

    My doc who is a cardiologist referred to by local medicenter when it was found out my Trigs were 235 and Total Cholesterol were 295, LDL 195, HDL 57, promptly put me on 5 mg Crestor to lower trigs and LDL, never discussed diet or anything with me. His office plastered with Pfizer Lipitor posters and Crestor bags given by pharma reps.

    Heres the kicker, this was all done with blood work that was NON-FASTING. I had blood drawn an hour after I had eaten eggs and bacon. This was also around halloween time too when I was over indulging on ALOT of Sub sandwiches and bread and lots and lots of candy. I love peanut butter cups. But I know 5 a day is excessive, which was my intake.  Was I getting a DOUBLE Whammy increasing my Trigs?

    Since I found this blog, I've been taking my Crestor which I don't want too. But have taken up the no wheat diet and HFC out of my diet that Dr Davis suggests. Dropped 18 pounds in a matter of weeks.

    Took my own cholesterol with one of those home machines after 4 weeks of Crestor. Doctor wants to test after 3 months. But my Total Cholesterol was 151, calculated LDL 87, HDL 50 and Trigs 69. I wonder how much was the Crestor doing the change or the change in my diet and 18 pound weight loss?

    Sorry for the rambling, but Dr. Davis your blog does give great info and brings peace of mind to me.

    Anonymous,

    Absolutely not. Having elevated triglycerides immediately after a meal is not a dangerous thing. It's only when they are chronically elevated that you are in danger. Same thing with insulin. Chronically elevated levels are the problem.

    Both of these are caused by excessive sugar/carb consumption.

    Interesting series of posts. But keep one thing in mind: Excess blood glucose is converted to palmitic acid by the liver...a saturated fat.

    (This fact alone should give the anti-saturated-fat crowd pause...if the body could have evolved to convert glucose to any type of fat, why did it evolve to produce a saturated fat? Can't be too bad for you...)

    Anyway, if the body through DNL produces a saturated/healthy fat after only a very brief (and normal) spike in blood glucose - after which the glucose returns to a normal fasting level - then high starch (not fructose) diet appears to be quite healthy. This would answer the question of why a rice-base culture can maintain good health while consuming a diet high in starches...in effect, they are eating a high saturated fat diet.

    If they don't eat continuously, allowing their bodies time to eliminate the excess blood glucose and the attendant insulin spike before the DNL triglycerides (palmitic acid) hits their blood stream, then there is no insulin-driven storage of the fats. Instead, they have elevated blood-borne fats that remain available for a consistent energy source of over time, of a type that their body prefers and has evolved to produce.

    Can you get the same effect from eating saturated fat in the first place? Yes. But to assume that this is better than the starch-driven approach you have to accept that higher levels of ANY saturated fat in the bloodstream is unhealthy. Which runs counter to the viewpoint of paleo and low-carb eaters.

    As Stephen has pointed out, there is no evidence that post-prandial glucose spikes are dangerous to someone with a healthy metabolism (i.e. not a type I or II diabetic). So, if there is no evidence of danger from a post-starch-meal spike, why would your body care where it got its saturated fat? Either dietary or liver-produced, it’s all the same once it is in your blood.

    Following the chain of reasoning further, a high-starch diet that leads to DNL production of palmitic acid would be healthier than a high fat diet composed of vegetable oil or other undesirable fats.

    We have to be very careful about quickly latching onto bits of "evidence" that confirm our biases. Remain scientific, think it through. The human body is an amazingly complex organism; when we begin to isolate its responses to prove our points, we can start down a path that leads to conclusions that may satisfy our dietary worldview, but are not entirely accurate.

    Scott W

    Note: If we are being carefully scientific in our approach, we should be careful to distinguish our descriptive terms for non-fat and non-protein calorie sources. "Carbohydrates" is too general. It encompasses fructose, which as a much different effect on the liver than glucose. My discussion above focuses on starches for a reason; they break down to glucose, which the body has evolved to handle efficiently, even in large quantities. It can handle fructose, too, but did not experience it in large quantities prior to modern times. Even using the term "sugar" is inaccurate, since it is half fructose and half glucose. By extension of my discussion above, eating pure glucose powder (dextrose) would be as healthy for a rice-based culture as eating white rice itself. You are simply giving the body the end product of rice digestion (glucose), from which it can produce palmitic acid.

    There's no question that postprandial triglyceride-rich lipoproteins are causally related to atherosclerosis, regardless of whether they were fat-driven or carbohydrate-driven.

    However, these brief posts are NOT meant to endorse low-fat diets. They are meant to show that a simple low-fat vs. low-carb approach is too simple-minded. There are other aspects of diet that count for substantial effects. Postprandial phenomena are one important class of effects that cannot be fully controlled by just controlling carbohydrate or fat content of the diet.

    You still haven't explained why the chart in your previous post (Di Novo Lipo-what?), where normoinsulinemic people have lower DNL on a high-fat diet, is in marked contrast to the chart of Gretchen in the post before that (Gretchen's postprandial diet experiment II) when she was eating high-fat.  From those two posts, it seems that peoples' postprandial triglyceride level is dependent on the amount of insulin they produce (and obviously how sensitive they are to that insulin).  Therefore a high-fat diet is not problematic unless one is also hyperinsulinemic.
