Peripheral Artery Disease, or P.A.D., is a serious condition that more than doubles your risk of heart attack or stroke.
P.A.D. is when the arteries in your legs begin to narrow from plaque and the flow of oxygen-rich blood is restricted. (Plaque is a buildup of cholesterol and other materials in the walls of your arteries.) If this is happening in your legs, it is likely happening in the arteries in your heart or brain. If the plaque ruptures, microscopic particles in the blood, called platelets, can stick together, causing clots to form on the damaged area. When these clots block the flow of blood to your heart or your brain, the result can be a heart attack or stroke.
Poor circulation in the arteries of your legs is serious enough. But it may also be a warning sign of a similar problem in the arteries leading to your heart or your brain. In fact, about 60% of P.A.D. patients have blockages in their arteries near their heart or brain as well as in their legs.
