Medical consensus once supported daily use of low dose aspirin to prevent heart attack and stroke in people at increased risk for cardiovascular disease (CVD). But in 2018, three major clinical trials cast doubt on that conventional wisdom, finding few benefits and consistent bleeding risks associated with daily aspirin use. Taken together, the findings led the American Heart Association and American College of Cardiology to change clinical practice guidelines earlier this year, recommending against the routine use of aspirin in people older than 70 years or people with increased bleeding risk who do not have existing cardiovascular disease.
Aspirin use is widespread among groups at risk for harm including older adults and adults with peptic ulcers – painful sores in the lining of the stomach that are prone to bleeding that affect about one in ten people. In a research report published today in Annals of Internal Medicine, researchers from Beth Israel Deaconess Medical Center (BIDMC) report on the extent to which Americans 40 years old and above use aspirin for primary prevention of cardiovascular disease.
“Although prior American Heart Association and American College of Cardiology guidelines recommended aspirin only in persons without elevated bleeding risk, the 2019 guidelines now explicitly recommend against aspirin use among those over the age of 70 who do not have existing heart disease or stroke,” said senior author Christina C. Wee, MD, MPH, a general internist and researcher at BIDMC and Associate Professor of Medicine at Harvard Medical School. “Our findings suggest that a substantial portion of adults may be taking aspirin without their physician’s advice and potentially without their knowledge.”
