Why haven't you heard about lipoprotein(a)?

Lipoprotein(a), or Lp(a), is the combined product of a low-density lipoprotein (LDL) particle joined with the liver-produced protein, apoprotein(a).

Apoprotein(a)'s characteristics are genetically-determined: If your Mom gave the gene to you, you will have the same type of apoprotein(a) as she did. You will also share her risk for heart disease and stroke.

When apoprotein(a) joins with LDL, the combined Lp(a) particle is among the most aggressive known causes for coronary and carotid plaque. If apoprotein(a) joins with a small LDL, the Lp(a) particle that results is especially aggressive. This is the pattern I see, for instance, in people who have heart attacks or have high heart scan scores in their 40s or 50s.

Lp(a) is not rare. Estimates of incidence vary from population to population. In the population I see, who often come to me because they have positive heart scan scores or existing coronary disease (in other words, a "skewed" or "selected" population), approximately 30% express substantial blood levels of Lp(a).

Then why haven't you heard about Lp(a)? If it is an aggressive, perhaps the MOST aggressive known cause for heart disease and stroke, why isn't Lp(a)featured in news reports, Oprah, or The Health Channel?

Easy: Because the treatments are nutritional and inexpensive.

The expression of Lp(a), despite being a genetically-programmed characteristic, can be modified; it can be reduced. In fact, of the five people who have reduced their coronary calcium (heart scan) score the most in the Track Your Plaque program, four have Lp(a). While sometimes difficult to gain control over, people with Lp(a) represent some of the biggest success stories in the Track Your Plaque program.

Treatments for Lp(a) include (in order of my current preference):

1) High-dose fish oil--We currently use 6000 mg EPA + DHA per day
2) Niacin
3) DHEA
4) Thyroid normalization--especially T3

Hormonal strategies beyond DHEA can exert a small Lp(a)-reducing effect: testosterone for men, estrogens (human, no horse!) for women.

In other words, there is no high-ticket pharmaceutical treatment for Lp(a). All the treatments are either nutritional, like high-dose fish oil, or low-cost generic drugs, like liothyronine (T3) or Armour thyroid.

That is the sad state of affairs in healthcare today: If there is no money to be made by the pharmaceutical industry, then there are no sexy sales representatives to promote a new drug to the gullible practicing physician. Because most education for physicians is provided by the drug industry today, no drug marketing means no awareness of this aggressive cause for heart disease and stroke called Lp(a). (When a drug manufacturer finally releases a prescription agent effective for reducing Lp(a), such as eprotirome, then you'll see TV ads, magazine stories, and TV talk show discussions about the importance of Lp(a). That's how the world works.)

Now you know better.

How to have a heart attack in 10 easy steps

If you would like to plan a heart attack in your future, here are some easy-to-follow steps to get you there in just a few short months or years:


1) Follow a low-fat diet.

2) Replace fat calories with "healthy whole grains" like whole wheat bread.

3) Eat "heart healthy" foods like heart healthy yogurt and breakfast cereals from the grocery store.

4) Use cholesterol-reducing plant sterols.

5) Take a multivitamin to obtain all the "necessary" nutrients.

6) Take the advice of your doctor who declares your heart "in great shape" based on your cholesterol values.

7) Take the advice of your cardiologist who declares your heart "like that of a 30-year old" based on a stress test.

8) Take a statin drug to reduce LDL and c-reactive protein while maintaining your low-fat diet.

9) Neglect sun exposure and vitamin D restoration.

10) Limit your salt intake while not supplementing iodine.



There you have it: An easy, 10-step process to do your part to help your local hospital add on its next $40 million heart care center.

If you would instead like to prevent a heart attack in your future, then you should consider not doing any of the above.

Kick inflammation in the butt

C-reactive protein, or CRP, is a protein produced by the liver in response to inflammatory signals its receives. Thus, CRP has emerged as a popular measure to gauge the underlying inflammatory status of your body. Higher CRP levels (e.g., 3.0 mg/L or greater) are associated with increased risk of heart attack and other cardiovascular events.

The drug cartel have jumped on this with the assistance of Harvard cardiologist, Dr. Paul Ridker. Most physicians now regard increased CRP as a mandate to institute statin therapy, preferably at high doses based on such studies as The JUPITER Trial, in which rosuvastatin (Crestor), 20 mg per day, reduced CRP 37%.

I see this differently. Two strategies drop CRP dramatically, nearly to zero with rare exception: Vitamin D restoration and wheat elimination. Not 37%, but something close to 100%.

Yes, I know it sounds wacky. But it works almost without fail, provided the rest of your life is conducted in reasonably healthy fashion, i.e., you don't live on Coca Cola, weigh 80 lbs over ideal weight, and smoke.

How can something so easily reduced like CRP mean you "need" medication? Easy: Increased CRP means there are fundamental deficiencies and/or inflammation provoking foods in your diet. Correct neither and there is an apparent benefit to taking a statin drug.

Why not just correct the underlying causes?

Life without Lipitor

One of the most common reasons people come to my office is to correct high cholesterol values without Lipitor. (Substitute "Lipitor" with Crestor, simvastatin, Vytorin, or any of the other cholesterol drugs; it's much the same.)

In the world of conventional healthcare, in which you are instructed to follow a diet that increases risk for heart disease and not advised to correct nutrient deficiencies like vitamin D and omega-3 fatty acids, then a drug like Lipitor may indeed provide benefit.

But when you are provided genuinely effective information on diet, along with correction of nutrient deficiencies, then the "need" and apparent benefits of Lipitor largely dissolve. While there are occasional genetic anomalies that can improve with use of Lipitor and other statins, many, perhaps most, people taking these drugs really would not have to if they were just provided the right information.

Anyone following the discussions on these pages knows that wheat elimination is probably one of the most powerful overall health strategies available. Wheat elimination reduces real measured LDL quite dramatically. Provided you limit other carbohydrates, such as those from fruits, as well, LDL can drop like a stone. That's not what your doctor tells you. This approach works because elimination of wheat and limiting other carbohydrates reduces small LDL. Small LDL particles are triggered by carbohydrates, especially wheat; reducing carbohydrates reduces small LDL. Conventional LDL of the sort obtained in your doctor's office will not show this, since it is a calculated value that appears to increase with reduced carbohydrates, a misleading result.

Throw vitamin D normalization and iodine + thyroid normalization into the mix (both are exceptionally common), and you have two additional potent means to reduce (measured) LDL. Not restricting fat but increasing healthy fat intake, such as the fats in lots of raw nuts, olive oil, and flaxseed oil reduce LDL.

While I still prescribe statins now and then, a growing number of people are succeeding without them.

(Note that by "measured" LDL I am referring to the "gold standard," LDL particle number by NMR provided by Liposcience. A second best is measured Apoprotein B available through most conventional labs.)

In search of wheat: Emmer

While einkorn is a 14-chromosome ancient wheat (containing the so-called "A" genome), emmer is a 28-chromosome wheat (containing the "A" and "B" genomes, the "B" likely contributed by goat grass 9000 years ago).

Both einkorn and emmer originally grew wild in the Fertile Crescent, allowing Neolithic Natufians to harvest the wild grasses with stone sickles and grind the seeds into porridge.

Having tested einkorn with only a modest rise in blood sugar but without the gastrointestinal or neurological effects I experienced with conventional whole wheat bread, I next tested bread made with emmer grain.

The emmer grain was ground just like the other two grains, cardiac dietitian Margaret Pfeiffer doing all the work of grinding and baking. Margaret added nothing but water, yeast, and a little salt. The emmer rose a little more than einkorn, but not to the degree of conventional whole wheat.

I tested my blood sugar beforehand: 89 mg/dl. I then ate 4 oz of the emmer bread. It tasted very similar to conventional whole wheat, but not as nutty as einkorn. Also not as heavy as einkorn, only slightly heavier than conventional whole wheat.

One hour later, blood sugar: 147 mg/dl. I felt slightly queasy for about 2-3 hours, but that was the end of it. No abdominal cramps, no sleep disturbance or crazy dreams, no nausea, no change in ability to concentrate.

I asked four other wheat-sensitive people to try the emmer bread. Likewise, nobody reacted negatively (though nobody tested blood sugar).

So it seems to me, based on this small, unscientific experience, that ancient einkorn (A) and emmer (AB) wheat seem to act like carbohydrates, similar to, say, rice or quinoa, but lack many of the other adverse effects induced by conventional wheat.

Modern wheat , Triticum aestivum, contains variations on the "A," "B," and "D" genomes, the "D" contributed by hybridization with Triticum tauschii at about the same time that emmer wheat hybridization occurred. It is likely that proteins coded by the "D" genome are the source of most of the problems with wheat products: immune, neurologic, gastrointestinal destruction, airway inflammation (asthma), increase in appetite, etc. This is consistent with observations made in studies that attempt to pinpoint the gliadin proteins that trigger celiac, the area in which much of this research originates.

If I ever would like an indulgence of cookies or cupcakes, I think that I will order some more einkorn grain from Eli Rogosa.

In search of wheat: Another einkorn experience

Lisa is a trained dietitian. Unlike many of her colleagues, she has "seen the light" and realized that the conventional advice that most dietitians are forced to dispense through hospitals, clinics, and other facilities is just plain wrong. 

I know Lisa personally and we've had some great conversations on diet and nutritional supplements. I told Lisa about my einkorn experience and how I witnessed a dramatic difference between bread made from einkorn wheat and that made from conventional whole wheat. So she decided to give it a try herself. 

Here's Lisa's experience:


This past Friday, June 18th, I conducted my "Einkorn Wheat Experiment".

7 am 
FBG [fasting blood glucose] 97 mg/dl

8 am-9 am 
1 hour high-intensity aerobic workout

10:05 am 
BG 99

10:05 am 
I embarked upon the journey of choking down, I mean enjoying, the hefty piece of Einkorn bread. Wow, was that bread dense!  It was a lot of work chewing. 

10:50 am 
(45 minutes after consumption, wanted to see what BG did a bit before the 1 hr mark)  BG 153

11:05 am 
1hr PP 120

11:35 am 
90 mins PP [postprandial] 113

12:05 pm 
2 hours PP  114 ... at this time I ate an egg & veggie omelet for lunch.

12:50 pm 
BG 100

Before dinner 5:10 pm 
BG 88

I was surprised with the BG of 153. However, it was good to see my insulin response is reactive and decreased BG 33 points in 15 minutes to end up with a BG of 120 1 hr after the bread.  

So, it appears my response is similar. A slight elevation of BG at the 1 hour mark, but not to the degree of conventional whole grain wheat bread.  

Of note, also, was the fact that I cannot remember the last time I ate a piece of wheat bread of this magnitude that did not make me bloated... not at all: No cramps, no brain fog, no headache and, did I mention not bloated?  

I believe you are on to something with tolerance of Einkorn wheat for those of us with wheat sensitivities, in addition to its apparent lower glycemic response.

Along with Lisa, I asked four other people with various acute intolerances (all gastrointestinal) to conventional wheat, i.e., people who experience undesirable effects from wheat within minutes to several hours, to eat the einkorn bread. None experienced their usual reactions.

Obviously, this does not constitute a clinical trial. Nonetheless, I find this a compelling observation: People like myself who generally experience distinct undesirable reactions to wheat did not experience these reactions with einkorn.

Note, however, that einkorn behaves like a carbohydrate. No different, say, from brown rice or quinoa. However, unlike modern whole wheat flour from Triticum aestivum,  in this little experience there were no immune reactions, no neurologic phenomena, no gastrointestinal distress--just the blood sugar consequences.

While this may not be true for all people consuming einkorn, it suggests that primordial einkorn wheat is quite different from modern conventional wheat for most people.

Increased blood calcium and vitamin D

Conventional advice tells us to supplement calcium, 1200 mg per day, to preserve bone health and reduce blood pressure.

Here's a curious observation I've now witnessed a number of times: Some people who supplement this dose of calcium while also supplementing vitamin D sufficient to increase 25-hydroxy vitamin D blood levels to 60-70 ng/ml develop abnormally high levels of blood calcium, hypercalcemia.

This makes sense when you realize that intestinal absorption of calcium doubles or quadruples when vitamin D approaches desirable levels. Full restoration of vitamin D therefore causes a large quantity of calcium to be absorbed, more than you may need. In addition, two studies from New Zealand suggest that 1200-1300 mg calcium with vitamin D per day doubles heart attack risk.

We have 20 years of clinical studies demonstrating the very small benefits of supplementing calcium to stop or slow the deterioration of bone density (osteopenia, osteoporosis). These studies were performed with no vitamin D or with trivial doses, too small to make a difference. I believe those data have been made irrelevant in the modern age in which we "normalize" vitamin D.

Should hypercalcemia develop, it is not good for you. Over long periods of time, abnormal calcium deposition can occur, leading to kidney stones, atherosclerosis, and arthritis.

Until we have clarification on this issue, I have been advising patients to take no more than 600 mg calcium supplements per day. I suspect, however, that the vast majority of us require no calcium at all, provided an overall healthy diet is followed, especially one that does not leach out bone calcium. This means no foods like those made with wheat or containing powerful acids, such as those in carbonated drinks.

Heart health consultation with Dr. Joe D. Goldstrich

Cardiologist, nutritionist, and lipidologist, Dr. Joe D. Goldstrich, is a frequent contributor to the Track Your Plaque Forum, where we discuss the full range of issues relevant to coronary health and coronary plaque reversal.

I have come to value Dr. Goldstrich's unique insights, especially in nutrition. Formerly National Director of Education and Community Programs for the American Heart Association and a physician at the Pritikin Center, his dietary philosophy has evolved away from low-fat and towards a low-carbohydrate focus, much as we use in Track Your Plaque. Like TYP, Dr. Goldstrich is always searching for better answers to gain control over coronary health. His unique blend of ideas and background has helped us craft new ideas and strategies. Dr. Goldstrich has proven especially adept at understanding how to incorporate new findings from clinical studies in our framework of coronary atherosclerotic plaque management strategies.

Dr. Goldstrich is offering to share his expertise with our online community. If you would like a one-on-one phone consultation with Dr. Goldstrich, you can arrange to speak with him at his HealthyHeartConsultant.com website.

Wheat aftermath

Following my 4 oz whole wheat misadventure that yielded the sky-high blood sugar of 167 mg/dl, compared to einkorn wheat's 110 mg/dl, I suffered through a 36-hour period of misery.

After I obtained the blood sugar of 167 mg/dl, I biked hard for one hour. This yielded a blood sugar back down in the 80s. I felt spacey in the ensuing few hours, as well as a little queasy. However, about 12 hours later, I awoke with overwhelming nausea along with that hypersalivating thing that happens just prior to vomiting. It did not come to that, but persisted all through the following day.

The next morning, I could barely concentrate. Trying to read a study (admittedly on the complex topic of agricultural genetics), I had to read each paragraph 4 or 5 times. Abdominal cramps and a bloated feeling also developed, though I was able to eat.

The 2nd night was filled with incredibly vivid dreams and intermittent sleeplessless. I awoke about 5 times through the night, but periods of sleep were filled with detailed, colorful dreams. I dreamt that a large corporation was secretly trying to gain control over the world's water supply, and I snuck onto a complex underwater vessel that was exploring and mapping the coastline of the Great Lakes in preparation. Weird.

I recognized these odd feelings as various facets of wheat intolerance, since they were all reminiscent of feelings I used to experience before I removed wheat from my diet. They were amplified and compressed, likely because I had been wheat-free for so long.

The odd thing is that, despite the modest blood sugar effect of my einkorn experience, none of the gastrointestinal or neurologic effects of wheat developed. So far, two other people with acute gastrointestinal wheat sensitivities have consumed our einkorn bread, also without reproduction of their usual symptoms.

Einkorn contains gluten, though the structure of the many gluten proteins of einkorn differs from that of the wheat bread I consumed, an example of modern Triticum aestivum. 14-chromosome einkorn carries what biologists call the "A" genome, while Triticum aestivum has the combines genomes of 3 plants, the combination of the A, B, and D genomes. It is the D genome that contains the genes coding for the most obnoxious, immunogenic forms of gluten.

So einkorn may not be entirely benign, but it is a good deal less obnoxious than modern Triticum aestivum.

I am awaiting the reports from a few other people on their experiences.

In search of wheat: Einkorn and blood sugar

There are three basic aspects of wheat's adverse health effects: immune activation (e.g., celiac disease), neurologic implications (e.g., schizophrenia and ADHD), and blood sugar effects.

Among the questions I'd like answered is whether ancient wheat, such as the einkorn grain I obtained from Eli Rogosa, triggers blood sugar like modern wheat.

So I conducted a simple experiment on myself. On an empty stomach, I ate 4 oz of einkorn bread. On another occasion I ate 4 oz of bread that dietitian, Margaret Pfeiffer, made with whole wheat flour bought at the grocery store. Both flours were finely ground and nothing was added beyond water, yeast, olive oil, and a touch of salt.

Here's what happened:

Einkorn wheat bread:

Blood sugar pre: 84 mg/dl
Blood sugar 1-hour post: 110 mg/dl

Conventional wheat bread
Blood sugar pre: 84 mg/dl
Blood sugar 1-hour post: 167 mg/dl

The difference shocked me. I expected a difference between the two, but not that much.

After the conventional wheat, I also felt weird: a little queasy, some acid in the back of my throat, a little spacey. I biked for an hour solid to reduce my blood sugar back to its starting level.

I'm awaiting the experiences of others, but I'm tantalized by the possibility that, while einkorn is still a source of carbohydrates, perhaps it is one of an entirely different variety than modern Triticum aestivum wheat. The striking difference in blood sugar effects make me wonder if einkorn eaten in small quantities can keep us below the Advanced Glycation End-Product threshold.

Are you hungry?

Eliminate modern high-yield semi-dwarf Triticum aestivum . . . and what is the effect on appetite?

A reduction in appetite is among the most common and profound experiences resulting from wheat elimination. I know that I have personally felt it: Wake up in the morning, little interest in breakfast for several hours. Lunch? Maybe I'll have a few bites of something. Dinner . . . well, I'd like to exercise first.

The wheatless report that:

--Appetite diminishes to the point where you can't remember whether you've eaten or not. It is not uncommon to miss a meal, perfectly content. Calorie intake drops by 400 calories per day, on average, calories you otherwise would not have needed but all went to . . . you know where.
--Hunger feels different: It's not the gnawing, rumbling hunger that plagues you every 2 hours. In its place, you will find that hunger feels like a soft reminder that, gee, maybe it's time to have something to eat because you haven't had anything in--what?--4 to 6 hours. And it's a subtle reminder, not a desperate hunt that makes you knock people aside at the food bar, steal coworkers' lunches stored in the refrigerator, salivating at the mere thought of food.
--The simplest foods satisfy--It no longer requires an all-you-can-eat buffet to satisfy, but a few small pieces of healthy food. (Yeah, but what happens to revenues at Kraft, Nabisco, and Kelloggs, not to mention the revenues at agribusiness giants ADM and Monsanto? Slash consumption by, say, 30%, you likewise slash revenues by 30%. What would shareholders say?)
--Even prolonged periods of not eating, i.e., fasting, is endured with ease.

Hunger and the relentless search for something to eat disappear for most people. By eliminating the appetite-stimulating properties of wheat, we return to a natural state of eating for sustenance, to satisfy physiologic need. We are no longer victims of this incredibly powerful appetite-stimulant called gliadin from wheat.

This is why many diets fail: They fail to remove this powerful appetite stimulant. You might eat only lean meats, limit your calories, and exercise 90 minutes per day, but as long as the gliadin protein is pushing your appetite button, you will want to eat more or you will have to mount monumental willpower to resist it. You can lose 20 pounds on phase 1 of the South Beach diet, for instance, only to regain it in phases 2 and 3 when "healthy whole grains" are added back.

So the key is to remove the gliadin protein from your life, i.e., eliminate all things wheat.

 

Chocolate . . . for adults only

If you've got a serious chocolate addiction and you'd like to make it as healthy as possible, give this X-rated dark chocolate a try.
I call it X-rated because it is certain to not satisfy young, sugar-craving palates, but is appropriate for only the most serious chocolate craver. This is a way to obtain the rich flavors and textures of cocoa, the health benefits (e.g., blood pressure reduction, antioxidation) of cocoa flavonoids, while obtaining none of the sugars/carbohydrates . . . and certainly no wheat!

It is easy to make, requiring just a few ingredients, a few steps, and a few minutes. Set aside and save for an indulgence, e.g., dip into natural peanut or almond butter.

Ingredients:
8 ounces 100% unsweetened cocoa
5 tablespoons coconut oil, melted
1/2 cup dry roasted pistachios
1/4 cup whole flaxseeds or chia seeds
Truvia or other non-aqueous sweetener

Using double-boiler method, melt cocoa. Alternatively, melt cocoa in microwave in 15-20 second increments. Stir in coconut oil, pistachios, and flaxseeds or chia seeds. Stir in sweetener, mixing thoroughly. (Note that the sweetener must be non-aqueous, as water-based sweeteners will separate in the oils.)

Lay a sheet of parchment paper out on a large baking pan. Pour chocolate mixture slowly onto paper, tilting pan carefully to spread evenly until thickness of thick cardboard obtained. Place pan in refrigerator or freezer for 20 minutes.

Remove chocolate and break by hand into pieces of desired size.

"Friday is my bad day"

At the start, Ted had a ton of small LDL particles. His starting (NMR) lipoprotien values:

LDL particle number: 2644 nmol/L

Small LDL: 2301 nmol/L

In other words, approximately 85% of all LDL particles were abnormally small. I showed Ted how to use diet to markedly reduce small LDL particles, including elimination of wheat, limiting other carbohydrates, and even counting carbohydrates to keep the quantity no higher than 15 grams per meal ("net" carbs).

Ted comes back 6 months later, having lost 14 pounds in the process (and now with weight stabilized). Another round of lipoproteins show:

LDL particle number: 1532 nmol/L

Small LDL: 799 nmol/L

Better, but not perfect. small LDL persists, representing nearly 50% of total LDL particle number.

So I quiz Ted about his diet. "Gee, I really stick to this diet. I have nothing made of wheat, no sugars. I count my carbs and I almost never go higher . . . except on Fridays."

"What happens on Friday?" I asked.

"That's when I'm bad. Not really bad. Maybe just a couple of slices of pizza. Or I'll go out for a big custard cone or something. That wouldn't do it, would it?"

That's the explanation. Your liver is well-equipped to recognize normal, large LDL particles. Large LDL particles therefore "live" for only a couple of days in the bloodstream. But the human liver does not recognize the peculiar configuration of small LDL particles, so it lets them pass--over and over and over again. The result: Once triggered by, say two slices of pizza, small LDL particles persist for 5 days, sometimes longer.

So Ted's one "bad" day per week is enough to allow a substantial quantity of small LDL particles to persist. While a fat indulgence (if there is such a thing) pushes large LDL up, the effect is relatively short-lived. Have a carbohydrate indulgence, on the other hand, and small LDL particles persist for up to a week. It means that Ted's one "bad" day per week is enough to allow his small LDL particles to persist at this level, preventing him from gaining full control over coronary plaque.

It also means that, if you have blood drawn for lipoprotein analysis but had a carbohydrate goodie within the previous week, small LDL particles may be exaggeratedly high.

HDL 80 mg/dl

More and more people in my clinic are showing HDL cholesterol values of 80 mg/dl or higher, males included.

Think about it: Nationwide, average HDL for males is 42 mg/dl and for females 52 mg/dl. Even though these average values are generally regarded as favorable, HDL cholesterol values at these levels are nearly always associated with higher levels of triglycerides, postprandial (after-eating) lipoprotein abnormalities, and excessive quantities of small LDL particles.

HDL particles are, of course, protective and are powerfully anti-oxidative. Higher levels of HDL have been associated with reduced potential for cancer, as well as reduced risk for heart disease.

Following the simple regimen that we follow to gain control over coronary plaque has therefore increased levels of HDL to heights that are uncommon in the rest of the population, levels that readily top 80, 90, or 100 mg/dl. That regimen includes:

1) Elimination of all wheat--Yes, consumption of "healthy whole grains" sets you up to have lower HDL levels; elimination of wheat increases HDL.
2) Limited carbohydrate consumption--While eliminating wheat is a powerful nutritional strategy to increase HDL, non-wheat carbohydrates like quinoa, millet, beans, rice, and fruit can still cause high triglycerides that lead to reduced levels of HDL. Limited exposure helps keep HDL at higher levels.
3) Omega-3 fatty acid supplementation--Because omega-3 fatty acids reduce both triglycerides and blunt the postprandial rise in lipoproteins that can cause HDL degradation, HDL rises with omega-3s from fish oil.
4) Vitamin D supplementation--The effect is slow, but it is BIG. HDL just goes up and up and up over about 2 years of supplementation. Before vitamin D, HDL levels of 60 mg/dl were the best I could hope for in most people. Now 80 mg/dl is an everyday occurrence.

Other factors can also be used to increase HDL levels, such as weight loss, red wine and alcohol, exercise, cocoa flavonoids, green tea, and niacin. But following the regimen above sends HDL through the roof in the majority.

Lessons from the 20-year statin experience

Readers of the Heart Scan Blog know that, while I recognize that statins are useful in a small segment of the population with genetically-determined disorders, they are wildly overused, misused, and abused. In my view, the majority of people taking statins have no business doing so and could, in fact, obtain superior results by following some of the strategies advocated in these pages.

Nonetheless, the 30-year long statin experience has taught us some important lessons. Statin drugs have enjoyed more "research" than any other class of drugs ever conceived. They have received more media attention and embraced by more physicians than any other class of drugs. Combine these social phenomena and I believe that several lessons can be learned:

Small LDL particles and increased HbA1c--An evil duo

Small LDL particles are triggered by consumption of carbohydrates. Eat more "healthy whole grains," for instance, and small LDL particles skyrocket.

Increased hemoglobin A1c, HbA1c, a reflection of the last 60-90 days' blood sugars, is likewise a reflection of carbohydrate consumption. The greater the carbohydrate consumption and/or carbohydrate intolerance, the greater the HbA1c. Most regard a HbA1c of 6.5% or greater diabetes; values of 5.7-6.4% pre-diabetes. However, note that any value of 5.0% or more signifies that the process of glycation is occurring at a faster than normal rate. Recall that endogenous glycation, i.e., glucose modification of proteins, ensues whenever blood sugars increase over the normal range of 90 mg/dl (equivalent to HbA1c of 4.7-5.0%). Glycation is the fundamental process that leads to cataracts, arthritis, and atherosclerosis.

Put the two together--increased quantity of small LDL particles along with HbA1c of 5.0% or higher--and you have a powerful formula for heart disease and coronary plaque growth. This is because small LDL particles are not just smaller; they also have a unique conformation that exposes a (lysine residue-bearing) portion of the apoprotein B molecule contained within that makes small LDL particles uniquely glycation-prone. Compared to large LDL particles, small LDL particles are 8-fold more prone to glycation.

So glycated small LDL particles are present when HbA1c is increased above 5.0%. Small, glycated LDL particles are poorly recognized by the liver receptor that ordinarily picks up and disposes LDL particles, unlike large LDL particles, meaning small LDL particles "live" much longer in the bloodstream, providing more opportunityt to do its evil handiwork. Curiously, small LDL particles are avidly taken up by inflammatory white blood cells that can live in the walls of arteries, where they are oxidized--"glycoxidized"--and add to coronary atherosclerotic plaque.

The key is therefore to tackle both small LDL particles and HbA1c.

Unforgiving small LDL particles

Small LDL particles are triggered by carbohydrates in the diet: Eat carbohydrates, small LDL particles go up. Cut carbohydrates, small LDL particles go down.

A typical scenario would be someone starts with, say, 2000 nmol/L small LDL (by NMR) because they've been drinking the national Kool Aid of eating more "healthy whole grains" and consuming somewhere around 200 grams carbohydrates per day, including the destructive amylopectin A of wheat. This person slashes wheat followed by limiting other carbohydrates and takes in, say, 40-50 grams per day. Small LDL: 200 nmol/L.

In other words, reducing carbohydrate exposure slashes the expression of small LDL particles, since carbohydrate deprivation disables the liver process of de novo lipogenesis that forms triglycerides. Abnormal or exaggerated postprandial (after-eating) lipoproteins that are packed with triglycerides are also reduced. Because triglycerides provide the first lipoprotein "domino" that cascades into the formation of small LDL particles, carbohydrate reduction results in marked reduction in small LDL particle formation.

Heart scan book



There are only two books on heart scans available.

One, of course, is Track Your Plaque.

The other is the basic book on heart scans, What Does My Heart Scan Show?

Lost in the navigation column to the left on this blog is the link to get the electronic version of the book. In case you didn't know, we make this available for free.

If you're interested, just go here. This book can provide many basic answers to the questions that often arise regarding heart scans, such as the expected rate of increase in score, how your score compares to other people, when should a stress test be considered. Many heart scan centers use this book for educational purposes to help patients understand the importance of their heart scan scores.

(The sign-up for the book requires that an e-mail address be entered.)

The hard copy of What Does My Heart Scan Show? is available from Amazon, also, for $12.99.
