Why does peripheral artery disease matter?
Peripheral artery disease happens when fatty deposits build up in arteries outside the heart, usually the arteries supplying fresh oxygen and blood to the arms, legs and feet.

Is PAD dangerous or life threatening?
Yes, PAD is dangerous because these blockages can restrict circulation to the limbs and organs. Without adequate blood flow, the kidneys, legs, arms and feet suffer damage. Left untreated, the tissue can die or harbor infection such as gangrene.

Does PAD cause additional health problems?
PAD may be the first warning sign of atherosclerosis– chronic fatty deposit build-ups throughout your arteries. The whole circulatory system, including your heart and brain, are at risk when arteries are blocked and narrowed. Fatty deposits also increase the risk for vascular inflammation and blood clots that can block the blood supply and cause tissue death.

PAD is a life-threatening condition that can be managed or even reversed with proper care.
