Peripheral Arterial Disease (P.A.D.) Overview
Peripheral arterial disease (P.A.D.) is a disease in which plaque builds up in the arteries that carry blood to the head, organs, and limbs. Plaque contains cholesterol, fat, fibrous tissue, calcium, and other substances in the blood. Plaque can harden and narrow in the arteries over time, limiting the flow of oxygen-rich blood to the organs and other parts of the body, a condition called atherosclerosis.
