In spite of the clear evidence of benefit of aspirin in the secondary prevention of cerebrovascular and cardiovascular thrombotic events, its use in patients at high risk due to a previous event remains suboptimal. A possible explanation for this underuse is concern regarding the relative benefit in relation to the potential risk for serious gastrointestinal events. ⋯ Aspirin use for the secondary prevention of thromboembolic events has a favorable benefit-to-risk profile and should be encouraged in those at high risk.
