Overview
Mechanism of benefit:
- Aspirin inhibits cyclo oxygenase and the subsequent suppression of thromboxane A2, the key moderator of irreversible platelet aggregation.
- Aspirin is a potent anti platelet agent and has been shown to improve survival and to prevent infarction in patients with unstable angina or after myocardial infarction.
Aspirin dosing:
- A 75-mg dose has been shown to be effective and causes less gastrointestinal bleeding than the commonly prescribed 325 mg dose.
- Aspirin also improves endothelial function and, when used in high dose (300 mg/day), has been shown to reduce circulating levels of C-reactive protein. Therefore, it should be started at 75 to 162 mg/day and continued indefinitely in all patients with chronic stable angina pectoris, unless contraindicated.
- 75 to 162 mg/day aspirin dosing range appears to have comparable efficacy for secondary prevention compared to dosing at 160-325 mg/day and also reduces bleeding risk.
- Use of warfarin in conjunction with aspirin and/or clopidogrel is associated with an increased risk of bleeding and should be monitored closely.
Supportive trial data:
- Meta-analysis of 140,000 patients from the Antiplatelet Trialists’ Collaboration showed that aspirin (75-325 mg/day) reduced the rate of subsequent myocardial infarction, stroke, and death in patients with history of angina pectoris, myocardial infarction, CABG, and stroke.
- In the Swedish Angina Pectoris Aspirin Trial (SAPAT), aspirin (75 mg/day) in conjunction with the beta blocker sotalol conferred an additional 34% reduction in acute myocardial infarction and sudden cardiac death among men and women with chronic stable angina.
