Post-stent protection | at Healthy Living Store

About six years ago, a friend of mine named Marina underwent an angioplasty procedure to insert a stent in a narrowed artery. Her doctor assured her that this was routine stuff. It's not a day at the beach, of course, but relatively simple and common.

Marina was nearly 80 when her stent was inserted, so she had qualms about undergoing post sten protection surgery, no matter how minor. I expect her doctor understood that some reassurance was needed, so his characterising of the procedure as routine was probably intended to calm her fears. At a younger age of course we would no doubt go into it a little deeper.

But I'm not a doctor, and you're not my patient, so I'll just come right out and tell you that the insertion of a stent should never be taken lightly, because while it may treat one problem, it very often leads to new complications that are not so easily solved.

Reading the fine print

You may have heard about the new stents that are coated with medication. They're called drug-eluting stents. The first were introduced in 2003, and in just three years they've more or less become the standard.

When I first heard of drug-coated stents I wondered what they might be coated with: A blood-thinning medication or maybe even a cholesterol-lowering statin? Good guess, but it turns out the medication is there to help prevent restenosis, which is the re-narrowing of an artery prompted by scarring and inflammation that may occur when stents are inserted.

That's right: The drug treats a problem caused by the stenting procedure.

Previous to the medicated stent era, the American College of Cardiology estimated that re-narrowing occurred in about 30 percent of patients who received stents. And in most restenosis cases, an additional angioplasty or even bypass surgery is required.

Unfortunately, drug-coated stents are not quite trouble-free. According to presentations made at the World Congress of Cardiology in Barcelona, Spain (as reported in a recent issue of Forbes), clinical trials sponsored by stent manufacturers show that drug-eluting stents sometimes cause blood clots. Which is not exactly what you're looking for in a treatment for a narrowed artery.

This problem may only occur in about six cases per every thousand, but it's enough of a concern that cardiologists are resorting to blood-thinning drugs more then they used to with non-medicated stents.

One doctor told Forbes that he prescribes Plavix (a blood thinner) for patients who receive drug-eluting stents. He adds that his stent patients may need to use Plavix for up to three years, and in some cases for the rest of their lives.

Studies have shown that folate, combined with other B vitamins, may be effective in preventing restenosis.

I told you about one of those studies in a past e- Alert. As reported in the Journal of the American Medical Association, 533 patients who had undergone coronary angioplasty were divided into two groups.

Half received a supplement of folic acid, vitamin B6 and B-12, while the other half received a placebo. Six months later, the researchers found that folate treatment not only slowed the development of plaque build up in the arteries, but in some cases also prevented it from occurring.

For some patients, chelation therapy provides a safe and considerably less expensive alternative to stent angioplasty. Chelation contains vitamins, minerals, and a synthetic amino acid called ethylene diamine tetracetic acid (EDTA) that binds with calcium deposits in the arteries and eliminates them from the body.

..and another thing
***********************************

Vitamin B-12 deficiency is a key risk factor for osteoporosis.

The question is: If you're B-12 deficient, how can you change that?

An HSI member named Mike writes: "In your current article about B-12, there is no mention of the problem some people and older people have of stomach acid deficiency, which in turn leads to the inability to make 'essential factor' which is necessary for the absorption of B-12 in the gut."

When I shared Mike's e-mail with HSI Panellist Dr Allan Spreen, he agreed, adding that the problem is more common than the medical profession lets on.

Dr. Spreen: "In my opinion this is why oral intake of B-12 pills is minimally effective for therapeutic purposes (though probably okay to avoid an overt deficiency state). For that reason most people use B-12 SL (Sub-Lingual, or under-the-tongue), which is an effort to bypass the stomach and utilise the capillary bed underneath the tongue for direct absorption of the nutrient.

"However, in a medical practice situation the gold standard is a B-12 injection, for the same reason. Anytime someone came into my office complaining of fatigue (any cause other than excessive partying the night before), they left with a B-12 shot...cheap, simple, and noticeably effective in a third of patients (by itself). Often, I also found that it seemed to 'prime the pump', causing the SL-form to become effective when it wasn't effective previously.

As for stomach acid deficiency, Dr. Spreen says that after B-12, the next supplement he adds to a patient's regimen (immediately following a strong multi-vitamin/mineral product) is usually a digestive enzyme/hydrochloric acid combination.
