Peripheral artery disease affects millions of people in the United States. It’s basically hardening of the arteries (atherosclerosis) leading to problems with getting enough blood to the limbs. Symptoms of severe PAD include leg pain that doesn’t go away once exertion stops and wounds that heal slowly or not at all.
Lifestyle changes, medication and surgery can address some cases of PAD, but often the disease is not recognized until it has advanced considerably. At Emory, cardiologist Arshed Quyyumi has been exploring whether a patient’s own bone marrow cells can repair the arteries in his or her limbs.
