In the EdoxabaN versus warfarin in subjectS UndeRgoing cardiovErsion of Atrial Fibrillation study (NCT 02072434), edoxaban showed similar efficacy and safety versus enoxaparin-warfarin in patients underwent electrical cardioversion of nonvalvular atrial fibrillation. In this ancillary analysis, we compared the primary efficacy (composite of stroke, systemic embolic event, myocardial infarction, cardiovascular death, and overall study period) and safety (composite of major and clinically relevant nonmajor bleeding, on-treatment) end points in relation to body mass index (BMI; <30 vs >= 30 kg/m(2)). We also compared cardioversion outcomes in relation to BMI. Of 2,199 patients enrolled, 1,095 were randomized to edoxaban and 1,104 to enoxaparin-warfarin. Mean age was 64 +/- 10 and 64 +/- 11 years and mean BMI 30.6 and 30.7 kg/m(2), respectively. Cardiovascular and metabolic diseases were more prevalent in obese (n = 1067) than nonobese patients. Overall ischemic event rates were low; rates in the BMI <30 kg/m(2) subgroup were numerically lower than the >= 30 kg/m(2) subgroup, but not significantly different (odds ratio [OR], 0.74 [95% confidence interval 0.23, 2.24]). Composite major + clinically relevant nonmajor bleeding rates were low and numerically lower, but not significantly different (OR 0.88 [0.38, 2.04]), between the edoxaban and enoxaparin-warfarin arms and across weight categories. Successful cardioversion rate was higher in the BMI <30 versus >= 30 kg/m(2) subgroup (73.9% vs 69.9%; OR 1.22 [1.01 to 1.48]). In EdoxabaN versus warfarin in subjectS UndeRgoing cardiovErsion of Atrial Fibrillation, BMI did not significantly impact the relative efficacy and safety of edoxaban versus enoxaparin-warfarin. Nevertheless, the nonobese group had a higher rate of cardioversion success than the obese group. (C) 2018 Elsevier Inc. All rights reserved.
