Track Your Plaque: Naughty or nice?

24. December 2007 William Davis (6)


Among the many wonderful surprises we've had at Track Your Plaque this holiday season was a letter from Santa Claus himself!

It seems that Santa, like the rest of us, has been busy surfing the web for useful health information the last few months. He was struck with this curious discussion we've been having about "wheat belly" and all the unhealthy consequences of wheat products in our diet.

He writes:

"I wouldn't have believed it myself, except that my waist size has grown four inches in as many years. Sure, I'm known for my healthy girth, but now even Mrs. Claus calls me fat!

"I was open to new ideas when I came across this crazy discussion about eliminating wheat from your diet. So I said, "What have I got to lose?" Well, four weeks later and 12 lbs lighter, I'm convinced. Now comes the tough part: I've got to deliver all the toys and resist all those cookies the children put out for me. I wonder if wheat makes reindeer fat, too?

"Anyway, thanks to your program I'm back to my old weight again. Doc says my blood sugar and blood pressure are also back down to normal. Thanks, Track Your Plaque! (You'll find something extra special under the tree this year.)"

And so it goes. I'm tempted to put Santa's testimonial on our homepage, but I think that may be tooting our own horn a bit too much.

Have a wonderful holiday!

    Thanks for the information Santa. I notice that you are drinking a Coke. You should lay off of that, too.

    Merry Christmas and Happy Hanukkah to fellow TYPers!!!  Here is to a successful 2008, slim Santas and if anyone sees Rudolph and his bright red nose, you might mention to him that drinking alcohol to excess raises triglyceride levels.

    There isn't much vitamin D in the North Pole, is there? Rudolph's red nose could also be remedied...

    But, Coke and cookies are soooo good!

    Love this post! Just thought I'd say HI! I found your blog via BlogRush!

    Hi, Santa!

    Thanks, as always, for your on-the-mark, pertinent information!

    However, Santa, with all due respect, Santa, Christmas is o-v-e-r, so please post a new blog, perhaps pertaining to the upcoming Valentine's Day, which would be perfectly appropriate, since that special day symbolizes "hearts".

Lipoprotein(a) and small LDL

Lipoprotein(a) and small LDL

4. May 2006 William Davis (1)
It's been my suspicion for some time that the combination of lipoprotein(a), or Lp(a), in combination with small LDL particles is a really bad risk for heart disease. People with this combination seem to have much higher heart scan scores for age than others. This seems to be a pattern that we'll see in the occasional woman less than 50 years old who already has a high heaert scan score. (It's unusual for women to have detectable coronary plaque before age 50.)

Very little data exists to support this idea and we are in the process of performing a small study to see whether it's true or not. My gut sense: it's among the most potent causes of coronary plaque around.

Case in point: Even though I spend a great deal of my time and energy advocating heart disease prevention, I still maintain my hospital privileges and skills. I had to cover one of the emergency rooms in town this past weekend (a requirement to maintain my hospital privileges).

One of the patients I saw was a 40-year old man--we'll call him Roland-- suffering a very large heart attack, a so-called "anterior myocardial infarction", or a heart attack involving the most important front portion of the heart. Thankfully, he came to the ER within 45 minutes after his chest pain started. The situation was immediately obvious and I was called to the ER. We quickly took him to the cardiac catheterization laboratory and put a stent in the left anterior descending artery and flow was restored. His chest pain dissipated over the next few minutes.

Nonetheless, Roland was left with a large area of reduced contraction of his heart muscle. Only time will tell how much recovery he'll have.

Roland was extremely lucky. The majority of people with closure of the artery that he'd experienced die within minutes. He did, in fact, "arrest" briefly, i.e., his heart became electrically unstable, though he recovered promptly.

Along with the multiple tubes of blood we required to run tests for his heart attack management, we had Roland's lipids and other measures sent off, as well. Wouldn't you know: Lp(a) and small LDL. This may have accounted for a heart attack at age 40.

Keep a lookout for this when you have lipoprotein testing. Conveniently, niacin can be used to treat both patterns, though higher doses are generally required for the Lp(a) part of the pattern. It's also my belief that the sort of Lp(a) measurement performed by the Liposcience laboratory (www.liposcience.com) is superior. They use a particle number based measure, not a weight-based measure. It is therefore independent of particle size, which can vary. Further work will, I believe, reveal some very important insights into the dreaded Lp(a).

    Just getting around to reading some of your older blog posts.

    Although I'm not completely certain, it's my impression that Marcovina was a student of Professor Sally McCormick of Otago University in New Zealand.

    http://biochem.otago.ac.nz/staff/mccormick/smccormick.html

    Notice they both participated in this seminal article.

    Sharp RH, Perugini MA, Marcovina SM, McCormick SPA: Structural features of apolipoprotein B synthetic peptides that inhibit lipoprotein(a) assembly. J Lipid Res 45:2227-2234, 2004.

    I'm very certain that Rebeca Sharp was a student at Otago.

    More importantly, Sally McCormick has applied for a patent mirroring the article title linked to above at wipo.int.  Don't have the link handy.
