Authors' conclusion

In CCS patients on OAC, OAC monotherapy reduces bleeding events compared to combination therapy, without clear evidence of a concomitant increase in ischemic risk.

Study context

Patients with chronic coronary syndrome and any indication for long-term oral anticoagulation (OAC)5 of 6 RCTs pooled
Participants
5,777 patients
Comparison
OAC monotherapy vs OAC plus single antiplatelet therapy
Outcome
Net adverse clinical events (NACE)
