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)
