P. A. D. is a serious disease that affects millions of Americans over age 50. The hardened arteries found in people with P.A.D. are a sign that they are likely to have hardened and narrowed arteries to the heart and the brain. That is why people with P.A.D. have a two to six times greater chance of death from a heart attack or a stroke.
When the blood flow to the legs is greatly (or severely) reduced, people with P.A.D. may have pain when walking. P.A.D. may cause other problems that can lead to amputation of: toe, foot, or a leg. People with P.A.D. may become disabled and not be able to go to work. As time goes on, they may have a very poor quality of life.
