Trends in preadmission oral anticoagulant use and clinical outcome in atrial fibrillation patients admitted with acute stroke in Denmark.

Aims: Use of oral anticoagulation (OAC) therapy has increased in recent years among patients with atrial fibrillation (AF). However, it remains uncertain whether this translates into improved clinical outcomes. We aimed to examine time trends in preadmission OAC use and clinical outcomes among AF patients admitted with stroke.
