NCT01847547

Brief Summary

This cohort study plans to identify initiators of oral anticoagulants using electronic claims data from a commercial insurance database to quantify associations between anticoagulant choice (warfarin and dabigatran) and the occurrence of selected outcomes in patients with non-valvular atrial fibrillation at risk for stroke.

    From treatment initiation until end of follow-up; up to 20 months

Secondary Outcomes (17)

  • Incidence Rate of Myocardial Infarction

    From treatment initiation until end of follow-up; up to 20 months
