What is peripheral arterial disease (PAD)?
Peripheral arterial disease (PAD) is a narrowing or blockage of the blood vessels in the legs. Blood flow to your feet and legs is decreased. This decreased blood flow affects the health of your skin on your feet and legs. It can also be the reason a foot ulcer does not heal. People with PAD have an increased risk for heart attack and stroke. An estimated 8 million people in the USA have PAD.
