Authors' conclusion

In patients with AF and stable CAD, OAC monotherapy, compared with OAC plus SAPT, was not associated with a statistically significant increased risk of ischemic events but resulted in a significantly reduced risk of bleeding.

Study context

Population
Patients with atrial fibrillation (AF) and stable coronary artery disease (CAD) (mean age 73.9 years, 20.1% women)
Participants
4,092 patients · 4 randomized controlled trials (RCTs)
Comparison
Oral anticoagulation (OAC) monotherapy vs OAC plus single antiplatelet therapy (SAPT)
Outcome
Composite of:
  • MI
  • Ischemic stroke
  • Systemic embolism or death (primary effectiveness)
  • Major bleeding (primary safety)
