  • AbstractBackgroundThe XANTUS study (NCT01606995) demonstrated low rates of stroke and major bleeding in patients with atrial fibrillation (AF) receiving rivaroxaban in clinical practice for the prevention of thromboembolic events (N = 6784).HypothesisBecause previous real‐world studies have not reported gender‐dependent responses to rivaroxaban treatment, this sub‐analysis of the XANTUS study investigated the effect of gender on outcomes.MethodsThe centrally adjudicated outcomes were compared between genders. Primary outcomes were major bleeding and all‐cause death. Secondary outcomes included symptomatic thromboembolic events. Multivariable Cox regression analysis was performed to assess the effect of risk factors on outcomes between genders.ResultsA total of 2765 female and 4016 male patients were included in the analysis. Baseline characteristics were generally similar. No nominally significant interaction between gender and risk factors for the study outcomes was observed. Rates of major bleeding, all‐cause death and symptomatic thromboembolic events in patients with non‐valvular AF receiving rivaroxaban for stroke prevention were similar in men and women; no significant differences in risk factors for these outcomes were observed between genders.ConclusionsFurther research is needed to better characterize the relative importance of different risk factors on outcomes in men vs women and to determine whether gender differences exist in patients treated with non‐vitamin K antagonist oral anticoagulants.
