title: Aspirin for the primary prevention of cardiovascular events.
abstract: There is significant evidence that low-dose aspirin is effective in preventing the first myocardial infarction in men and ischemic stroke in women. There is also an increased risk for major gastrointestinal tract hemorrhage and a suggestive, but nonsignificant, increase in the risk for hemorrhagic stroke. If there is a history of ulcer disease or upper-gastrointestinal tract bleeding, Helicobacter pylori should be eradicated (if present) and a proton pump inhibitor used with aspirin therapy. In conclusion, the benefits of low-dose aspirin (75-162 mg/day) in the prevention of myocardial infarction in men and thrombotic stroke in women generally outweigh the risks of serious bleeding in adults with a coronary heart disease risk >1% per year or >1% in 10 years.
