Daily low-dose aspirin can prevent heart attack and stroke but is often misused, from the January 2014 Harvard Heart Letter
Aspirin is often hailed as a wonder drug, thanks to its ability to help stave off heart attacks and clot-caused strokes. But fewer than half of people who could benefit from a daily low-dose aspirin take it, while many others take it when they shouldn't, reports the January 2014 Harvard Heart Letter.
If you don't have heart disease, but do have high blood pressure, diabetes, or other risk factors for heart disease, don't automatically assume that taking aspirin every day is a good idea. "A lot of people take aspirin who really shouldn't," says Dr. Christopher Cannon, a cardiologist at Brigham and Women's Hospital and professor of medicine at Harvard Medical School. "Everyone assumes aspirin is harmless, but it isn't." For some, the downsides of aspirin—mainly gastrointestinal bleeding—outweigh its benefits.
