Aspirin can help prevent a second heart attack, but most don’t take it

For people who have experienced a heart attack or stroke, taking a daily aspirin has been shown to help prevent a second one. Yet, despite aspirin’s low cost and its clear benefits in such scenarios, fewer than half of people worldwide who have had a heart attack or stroke take the medication, according to a new study led by researchers at Washington University School of Medicine in St. Louis and the University of Michigan. The study appears Aug. 22 in JAMA.
