Secondary prevention of stroke in patients with atrial fibrillation: factors influencing the prescription of oral anticoagulation at discharge.

Background: Oral anticoagulation (OAC) is the only treatment that has shown a significant benefit to reduce the risk of recurrence in patients with ischemic stroke and nonvalvular atrial fibrillation (NVAF). However, OAC is still underused, even at discharge from neurological centers. The objective of this study was to identify the reasons underlying the prescription of OAC at discharge after an ischemic stroke in patients with NVAF.
