Relation of Risk of Stroke in Patients With Atrial Fibrillation to Body Mass Index (From Patients Treated With Rivaroxaban and Warfarin in the ROCKET AF Trial)

We investigated stroke outcomes in normal weight (body mass index [BMI] 18.50-24.99 kg/m2), overweight (BMI 25.00-29.99 kg/m2), and obese (BMI ≥30 kg/m2) patients with AF treated with rivaroxaban and warfarin. We compared the incidence of stroke and systemic embolic events (SEE) as well as bleeding events in normal weight (n=3289), overweight (n=5535), and obese (n=5206) patients in a post-hoc analysis of the ROCKET AF trial. Stroke and SEE rates per 100 patient-years were 2.93 in the normal weight group (reference group), 2.28 in the overweight group (adjusted hazard ratio [HR] 0.81, 95% confidence interval [CI]: 0.66-0.99, p=0.04), and 1.88 in the obese group (adjusted HR 0.69, 95% CI: 0.55-0.86, p
