Peripheral artery disease (PAD) is common in the U.S., affecting almost 10 million people.
PAD occurs when arteries become narrow or blocked, decreasing blood supply in the legs. It’s caused by a buildup of plaque in the walls of arteries called atherosclerosis. PAD typically occurs in the legs, but it also may affect arteries that carry blood from the heart to the kidneys, head, arms or stomach. People with PAD have greater risk for coronary artery disease, heart attack and stroke.
What are the signs and symptoms of PAD?Classic symptoms of PAD typically include pain, fatigue or discomfort in the feet and legs that occurs during walking or exercise and then goes away after a few minutes of rest. Others with the disease may show signs of:
- Sores on legs or feet that heal slowly or not at all
- Skin that looks dark and blue
- Lower temperature in one leg compared to the other
- Weak or absent pulse in the legs or feet
- Erectile dysfunction
What is the treatment for PAD?Treatment for PAD is based on severity of the disease, risk factors and test results. Lifestyle changes that can help control PAD include:
- not smoking
- eating a healthy diet
- lowering blood pressure
- controlling cholesterol
- exercising regularly – walking at least 30 minutes for three days each week or 10,000 steps per day
Penn’s Vascular Medicine Program is conducting peripheral artery disease research studies to improve circulation in the legs of patients with PAD.
