Insights
Aspirin for primary prevention of cardiovascular disease is debated due to balanced risks and benefits. Personalized assessment of individual cardiovascular and bleeding risks is recommended, especially for those under 70.
Area of Science:
- Cardiology
- Preventive Medicine
- Pharmacology
Background:
- The role of aspirin in primary prevention of cardiovascular (CV) disease is under intense debate.
- Recent studies indicate that reductions in ischemic events with aspirin are offset by increased bleeding events.
- Improved global preventive measures (smoking cessation, exercise, lipid management) have lowered baseline CV risk.
Purpose of the Study:
- To analyze the benefits and harms of aspirin therapy for primary CV prevention.
- To evaluate aspirin's efficacy as a function of the 10-year risk of major adverse cardiovascular events (MACE).
- To advocate for a personalized and differentiated approach to aspirin prescribing.
Main Methods:
- Conducted a meta-regression analysis of aspirin's benefits and harms.
- Examined aspirin's effectiveness relative to the 10-year MACE risk.
- Considered patient-specific factors including CV and bleeding risks.
Main Results:
- Aspirin's net benefit in primary prevention is influenced by the individual's 10-year MACE risk.
- The balance of benefits versus bleeding risks necessitates an individualized risk-benefit assessment.
- General preventive strategies remain paramount.
Conclusions:
- A personalized approach to aspirin therapy in primary CV prevention is warranted.
- For patients under 70, clinicians should assess 10-year CV risk.
- Aspirin should be considered only for very high CV risk and low bleeding risk individuals, respecting patient preferences.
Abstract:
The need for aspirin therapy as part of primary prevention of cardiovascular (CV) disease is currently being highly debated, especially after 3 studies in different settings reported that a reduction in ischemic events is largely counterbalanced by an increase in bleeding events. One possible explanation for these results is the progressive reduction in the risk of major adverse cardiovascular events (MACE) as a result of primary prevention, which has accompanied global education programs that have led to patients smoking less, exercising more, and increasingly undertaking lipid-lowering therapies. Based on a meta-regression of the benefits and harmful effects of aspirin therapy in primary prevention as a function of the 10-year risk of MACE, we favor a differentiated and personalized approach that acknowledged differences between patients and emphasized an individualized assessment of benefits and risks. Following general preventive measures (physical exercise, cessation of smoking, treatment of hypertension and hypercholesterolemia, etc.), an individualized approach to prescribing aspirin is still warranted. When patients are less than 70 years of age, clinicians should assess the 10-year CV risk. Aspirin treatment should be considered only when the CV risk is very high and the bleeding risk is low, after taking into account the patient's preferences.
