Peripheral arterial disease (PAD) is a cardiovascular condition caused by atherosclerosis, or the buildup of plaque in the arteries outside of the heart. Although most frequent in the legs, PAD can occur in any artery. The condition is more common in blacks largely due to risk factors such as diabetes and high blood pressure.
PAD is very common — one in every 20 people in this country over the age of 50 is afflicted; yet, it is not a well-known illness. The lack of awareness can be costly. PAD increases the risk of heart disease, heart attack, stroke, and leg amputation.
Although cramping and pain in the legs that hinder walking and stair climbing is a common symptom, most people with PAD experience no symptoms at all. Screening for PAD is therefore very important.
