Background and objective: Thromboembolic risk is higher in women than men with non-valvular atrial fibrillation (NVAF). Published data indicate variability in antithrombotic use by gender and region. We analyzed gender-specific antithrombotic treatment patterns in Spain and rest of Western Europe (rWE) in patients with NVAF. Methods: GLORIA-AF (Phase III) is a global, prospective, observational study which enrolled newly diagnosed NVAF patients with CHA(2)DS(2)-VAScs >= 1 (2014-2016). Analyses were performed comparing antithrombotic treatments by gender in Spain and rWE. Results: This analysis included 1163 and 7972 patients from Spain and rWE, respectively. Stroke risk was higher in women than men in both Spain and rWE. While in rWE, bleeding risk and antithrombotic treatment pattern were similar between genders, in Spain bleeding risk in women was lower and more females compared to men received OACs (95.0% versus 92.4%, d= -0.1078, respectively). Fewer Spanish patients received...Show moreBackground and objective: Thromboembolic risk is higher in women than men with non-valvular atrial fibrillation (NVAF).

While in rWE, bleeding risk and antithrombotic treatment pattern were similar between genders, in Spain bleeding risk in women was lower and more females compared to men received OACs (95.0% versus 92.4%, d= -0.1078, respectively). Fewer Spanish patients received direct oral anticoagulants (DOACs) (women 32.1%, men 25.3%) than vitaminK-antagonists (VKAs) (women 63.0%, men 67.1%) vs. rWE patients. In Spain women received more DOACs compared to men (56.0% versus 44.0%). Conclusions: OAC rates were higher in Spain as compared to rWE. More women received OACs in Spain, while in rWE no difference by gender was observed. DOACs in rWE are the most prescribed OAC while in Spain, due to prescription barriers, its use remains low for both genders and VKAs are preferred. Spanish women received more DOACs compared to men.
