Study Urges Limits on Daily Aspirin

Daily aspirin probably should be limited to people who have a very high risk of heart disease or stroke, a large new study suggests. The reason is that the risk of bleeding is too high to be worth the risk, researchers said. The new study found bleeding risk to be higher than reported before. The study compared people who were taking low-dose aspirin daily with people who were not taking the drug. Each group included more than 186,000 adults. Low-dose aspirin was defined as 300 milligrams or less. In a 6-year period, more than 6,900 people had a first episode of major bleeding that required a hospital stay. Nearly 4,500 of the bleeding episodes were in the stomach or intestines. Nearly 2,500 were in the brain. Risk of bleeding was about 55% higher in the aspirin group than in the no-aspirin group. And people with diabetes had a higher risk of bleeding than others.
