AIM: In this subanalysis of the EXPAND study, we evaluated the risks and benefits of rivaroxaban plus antiplatelet therapy (APT) for patients with non-valvular atrial fibrillation (NVAF) complicated by stable coronary artery disease (CAD), ischemic stroke, or peripheral artery disease (PAD).
METHODS: From the EXPAND study population (n=7,141), patients with NVAF complicated by stable CAD (n=886), ischemic stroke (n=1,231), or PAD (n=160) were included. Patients complicated by any of them were set as ALL (n=2,030). Patients were all treated with rivaroxaban (10 or 15 mg/day) with (+) or without (-) APT. Efficacy outcomes were symptomatic stroke＋systemic embolism (SE), symptomatic stroke＋SE＋myocardial infarction＋cardiovascular death, and all-cause death. Safety outcomes included major and any bleeding. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated for differences between the APT(+) and APT(-) groups.
RESULTS: There were no significant differences in the efficacy outcomes between the APT(+) and APT(-) groups in the ALL cohort or in the CAD and STROKE sub-cohorts. In the PAD subcohort, the HR [95% CI] for all-cause death in the APT(+) group increased (4.43 [1.05-18.71]; p=0.043). In the APT(+) group, the HR [95% CI] for any bleeding increased in the ALL cohort (1.28 [1.01-1.62]; p=0.044) and STROKE subcohort (1.42 [1.01-2.01]; p=0.047), and for major bleeding in the CAD subcohort (2.00 [1.01-3.93]; p=0.046).
CONCLUSIONS: Rivaroxaban with APT did not reduce ischemic outcomes in patients with stable CAD or ischemic stroke; however, it did increase the risk of bleeding in patients with stable CAD or ischemic stroke.
