Area of Science:

  • Cardiology
  • Preventive Medicine
  • Pharmacology

Background:

  • Clinical trials confirm aspirin's efficacy in preventing myocardial infarction (MI) and stroke.
  • Aspirin's mechanism likely involves preventing coronary thrombosis in obstructive coronary artery disease.
  • Age is a significant risk factor for coronary artery disease (CAD).

Purpose of the Study:

  • To evaluate the role of prophylactic aspirin in preventing cardiovascular events.
  • To determine the optimal age group and dosage for aspirin prophylaxis.
  • To assess the benefits of aspirin in individuals with and without clinically evident CAD.

Main Methods:

  • Analysis of prospective randomized studies and observational studies.
  • Inclusion of data from male physicians and female nurses.
  • Focus on aspirin dosage (325 mg every other day or 1-6 times/week) and age demographics.

Main Results:

  • Aspirin significantly reduced myocardial infarction by 44% in male physicians aged 50+.
  • Aspirin reduced cardiovascular events by 32% in female nurses aged 50+.
  • Treatment effects were observed exclusively in participants aged 50 and older.

Conclusions:

  • Prophylactic aspirin is indicated for men and women aged 50 and older without contraindications.
  • A recommended dosage is 325 mg of aspirin every other day, associated with minimal side effects.
  • Aspirin prophylaxis may benefit individuals with risk factors for coronary artery disease, including advanced age.
