Comparison of treatment persistence with different oral anticoagulants in patients with atrial fibrillation

Oral anticoagugulants (OACs) effectively reduce the risk for ischemic stroke in patients with atrial fibrillation (AF), but undertreatment and poor persistence with treatment are important problems. NOACs now provide alternatives to warfarin. This study compares the persistence with presently available antithrombotic treatments in AF patients with a CHA2DS2VASc score ≥2. All first claims of either warfarin (n = 9969), dabigatran (n = 2701),...
