OBJECTIVES: The objective is to assess the comparative effectiveness and safety of dual-antiplatelet therapy (DAPT) vs triple therapy (TT) with DAPT + oral anticoagulant (OAC) in patients with anterior ST-segment elevation myocardial infarction (STEMI) and with new-onset anterior/apical wall-motion abnormalities (WMAs) treated with primary percutaneous coronary intervention (PCI).
BACKGROUND: Patients with STEMI and new-onset anterior/apical WMA may benefit from the addition of OAC to prevent left ventricular thrombus and cardioembolic events.
METHODS: A multicenter, retrospective cohort study was conducted. Patients with a concomitant indication for OAC were excluded. Patients discharged on TT were compared with patients discharged on DAPT using adjusted Cox proportional hazards analysis and inverse probability of treatment weighting. The primary endpoint was the net adverse clinical event (NACE) rate at 6 months (composite of all-cause mortality, non-fatal MI, stroke, or transient ischemic attack, systemic thromboembolism or type 3 or 5 Bleeding Academic Research Consortium [BARC] bleeding).
RESULTS: A total of 1666 patients were included, among which 627 were treated with TT and 1039 were treated with DAPT. A NACE occurred in 55 patients (6.03 per 100 patient-years) in the TT group and in 74 patients (7.18 per 100 patient-years) in the DAPT group (adjusted hazard ratio, 0.86; 95% confidence interval, 0.55-1.32). Adjusted risk of the individual components of the primary endpoint, ischemic events, and bleeding events were similar between both groups (P>.05 for all).
CONCLUSIONS: The addition of OAC to DAPT in anterior STEMI patients with new-onset WMA treated with PCI was not associated with a significant reduction in NACE.
