- acutely, should be considered for all patients with suspected myocardial infarction, unstable angina, or a history of myocardial infarction, angina, stroke, transient ischaemic attack, arterial bypass surgery, or angioplasty
- reduction of risk of thromboembolism

The Antithrombotic Trialists' Collaboration meta-analysis (1) showed that aspirin (or another antiplatelet drug) prevents serious vascular events in a wide range of high-risk patients, including people with previous MI, acute MI, prevous stroke or TIA, acute stroke, stable angina, intermittent claudication and - if oral anticoagulants are unsuitable - atrial fibrillation. A commentary on the meta-analysis (2) states that..'the documented effects of antiplatelet agents accross a wide range of patient groups suggests that low dose aspirin should be given routinely to patients at high or intermediate risk for cardiovascular events (above 2% per year).'
