Highlights Coronary Artery Disease Coronary artery disease (CAD), also called heart disease, is a condition in which fatty deposits called plaque build-up in the hearts arteries. These deposits cause arteries to become narrow and blocked, which restricts blood and oxygen flow to the heart muscle. CAD is the leading cause of death, for both men and women, in the United States. Risk Factors Some of the main risk factors that increase the risk for CAD are: Smoking Unhealthy cholesterol and lipid levels High blood pressure Diabetes Lack of exercise Obesity Symptoms Angina is the primary symptom of coronary artery disease. Angina feels like gripping pain or pressure in the chest area. Stable angina is predictable chest pain that lasts a few minutes or less and is usually relieved by rest or medication. It is often triggered by physical exertion or emotional stress. Unstable angina is unpredictable chest pain that occurs unexpectedly, even when at rest. It is a more serious condition than stable angina a...
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 .
