Balancing the risk and benefits of low-dose aspirin in clinical practice

Area of Science:

• Cardiology
• Pharmacology
• Preventive Medicine

Background:

• Aspirin is a cornerstone antiplatelet agent for cardiovascular event prevention.
• While effective, aspirin use is associated with significant bleeding risks, impacting clinical decisions.
• Balancing aspirin's benefits and risks is challenging in diverse patient populations.

Purpose of the Study:

• To review the evidence on aspirin's efficacy in cardiovascular prevention.
• To detail the risks of hemorrhagic complications associated with aspirin therapy.
• To propose a framework for individualized clinical decision-making regarding aspirin use.

Main Methods:

• Systematic review of scientific literature on aspirin's efficacy and safety.
• Analysis of data on cardiovascular event reduction and bleeding complications.
• Development of a unifying framework for risk-benefit assessment.

Main Results:

• Strong evidence supports aspirin's role in decreasing cardiovascular events across various conditions.
• Hemorrhagic complications, though rare, have substantial morbidity and mortality.
• The proposed framework aids clinicians in tailoring aspirin therapy based on individual risk profiles.

Conclusions:

• Individualized assessment of cardiovascular and bleeding risks is crucial for optimal aspirin therapy.
• The review provides tools for clinicians to navigate complex decision-making in aspirin prescription.
• Future strategies focus on refining individualized risk assessment for antiplatelet therapy.
