While high cholesterol (either as a high LDL or “bad” cholesterol; or low HDL or “good” cholesterol) certainly contributes to the risk of atherosclerosis and cardiovascular disease, it is not the only contributor. Each year it seems that I have one or two patients that have “no excuse” for having coronary artery disease but they do anyway.
In the same period of time, however, I will see hundreds of patients that have an obvious cause. When doctors see the cause they feel better. When families and patients know the reasons for the disease (have something to blame), they also seem happier. But life doesn’t always work that way. And when it doesn’t, it is sometimes hard to accept therapies that seem to be for diseases that we don’t think that we have.
Some reasons for major blockages that don’t necessarily involve high cholesterol or imbalanced cholesterol numbers include the following partial list:
High blood pressure , ...
Peripheral artery disease (P.A.D.) is a common circulatory problem, where narrowed arteries reduce blood flow to your limbs. P.A.D. is more common in African-Americans than any other group. This may be because some of the conditions which increase the risk of developing P.A.D., such as diabetes and high blood pressure, are very common among African-Americans.
“ P.A.D. occurs when extra cholesterol and other fats circulating in the blood collect in the walls of the arteries that supply blood to your limbs. This buildup—called plaque—narrows your arteries, often reducing or blocking the flow of blood… P.A.D. is most commonly seen in the legs, but also can be present in the arteries that carry blood from your heart to your head, arms, kidneys and stomach.”

So, what causes P.A.D?
While the cause of plaque buildup in the limbs are unknown for most individua...
Carotid artery surgery is a procedure to restore proper blood flow to the brain.
The carotid artery brings needed blood to your brain and face. You have one of these arteries on each side of your neck. Blood flow in this artery can become partly or totally blocked by fatty material called plaque. Such a blockage can reduce the blood supply to your brain and may cause a stroke.
There are two invasive ways to treat a carotid artery that has plaque buildup in it. This article focuses on a surgery called endarterectomy.
For more information on the other procedure, see: Angioplasty with stent placement .
