[Aspirin in cardiovascular prevention: does the approach differ by gender?]

Area of Science:

• Cardiology
• Preventive Medicine
• Pharmacology

Context:

• Aspirin's role in primary cardiovascular disease prevention is debated.
• Existing research often overlooks gender-specific benefits.
• Understanding sex-based differences is crucial for personalized medicine.

Purpose:

• To conduct a gender-specific meta-analysis on aspirin for primary cardiovascular disease prevention.
• To identify sex-based differences in aspirin's efficacy and impact.
• To explore the underlying reasons for these observed differences.

Summary:

• Aspirin therapy significantly reduces cardiovascular events in women primarily by lowering stroke risk.
• In men, aspirin therapy predominantly reduces myocardial infarction risk for primary prevention.
• These findings highlight distinct gender-specific benefits of aspirin in primary prevention.

Impact:

• Provides crucial insights into sex-based differences in aspirin efficacy for primary prevention.
• Informs personalized aspirin treatment strategies for cardiovascular disease.
• Highlights the need for further research into the mechanisms behind gender-specific effects.
