Dr. Timir Paul of East Tennessee State University’s Quillen College of Medicine recently received a $200,000 research grant from the University of Texas Southwestern to evaluate the “real world” effectiveness and use of non-stent and stent-based therapies among patients treated with peripheral artery disease.Peripheral artery disease is a narrowing of the peripheral arteries serving the legs, stomach, arms and head. PAD most commonly affects arteries in the legs. According to the American Heart Association, PAD affects over 8.5 million Americans and over 200 million people worldwide.
