Insights
Aspirin effectively prevents secondary cardiovascular events, with a number needed to treat of 25. However, it carries risks of bleeding, necessitating careful consideration for primary prevention in high-risk individuals.
Area of Science:
- Cardiology
- Pharmacology
- Preventive Medicine
Background:
- Randomized trials confirm aspirin's efficacy as an antiplatelet agent.
- Aspirin is established for secondary prevention of cardiovascular events.
Purpose of the Study:
- To evaluate the benefits and risks of aspirin therapy.
- To define guidelines for aspirin use in primary and secondary prevention.
Main Methods:
- Review of randomized controlled trials on aspirin.
- Analysis of number needed to treat (NNT) and number needed to harm (NNH) data.
- Assessment of risk stratification models for primary prevention.
Main Results:
- NNT for vascular event prevention is approximately 25.
- NNH for cerebral bleeding is about 1,000; for severe extracerebral bleeding, 100-200.
- Primary prevention is recommended for high-risk patients (≥1-1.5% annual risk).
Conclusions:
- Aspirin is a valuable tool for secondary cardiovascular event prevention.
- Risk-benefit assessment is crucial, especially for primary prevention.
- Further discussion on mechanisms, interactions, and aspirin resistance is warranted.
Abstract:
Many randomized trials have shown aspirin as an effective antiplatelet drug for the secondary prevention of cardiovascular events. The NNT (number needed to treat) to prevent 1 vascular event is about 25. The NNH (number needed to harm) inducing one cerebral bleeding is about 1'000, to provoke one severe extracerebral bleeding about 100-200. The primary prevention can be recommended only for high risk patients for cardiovascular events (annual risk of 1-1.5% or more), calculated on the basis of the Framingham data, the Sheffield tables or in analysis of U.S. Preventive Services Task Force. The mechanisms of action, interactions and the "aspirin-resistance" are briefly discussed.
