EurekAlert -- An analysis of previous studies indicates that among patients with peripheral artery disease, aspirin use is associated with a statistically nonsignificant decrease in the risk of a group of combined cardiovascular events (nonfatal heart attack, nonfatal stroke, and cardiovascular death), but is associated with a significant reduction in the risk of one of these events, nonfatal stroke, although the findings may be limited by the lack of a large study population, according to an article in the May 13 issue of JAMA.
