TIMI-AF score and cardiovascular events in vitamin K antagonists-naïve outpatients with atrial fibrillation.

Background: The TIMI-AF score predicts poor outcomes in patients with atrial fibrillation (AF) and guides selection of anticoagulant therapy by identifying clinical benefit of direct oral anticoagulants (DOACs) or vitamin K antagonists (VKA).

Hypothesis: Our objective was to determine the ability to predict cardiovascular events according to the TIMI-AF score in a real-world population.

Methods: Retrospective observational study of VKA-naïve patients with AF was seen at a cardiology outpatient clinic in Spain between November 2012 and August 2014.
