Objectives: To investigate the incidence of bleeding events in atrial fibrillation (AF) patients treated with vitamin K (VKAs) or non-vitamin K antagonist oral anticoagulants (NOACs) screened for the presence of liver fibrosis (LF). Background: Previous studies provided conflicting results on bleeding risk in AF patients with liver disease on VKAs, and no data on NOACs in this setting are available. Methods: Post-hoc analysis of a prospective, observational multicentre study including 2330 AF outpatients treated with VKAs (n = 1297) or NOACs (n = 1033).

Objective: To estimate the prevalence of nonalcoholic fatty liver disease (NAFLD) and its impact on bleeding and thrombotic events in patients with atrial fibrillation (AF). Patients and Methods: Prospective multicenter cohort study including patients with nonvalvular AF receiving vitamin K antagonists (VKAs) or non-VKA oral anticoagulants (NOACs) from February 2008 for patients on VKA and from September 2013 for patients on NOACs. NAFLD was diagnosed using the validated fatty liver index, with a cutoff score of 60 or higher.
