Recurrent vascular events in patients with ischemic stroke/TIA and atrial fibrillation in relation to secondary prevention at hospital discharge.

Background: Oral anticoagulation is indicated in secondary prevention of stroke or transient ischemic attack (TIA) in patients with atrial fibrillation, but it is often withheld because of contraindications and/or fear of bleeding complications.

Methods: We analysed recurrent cerebral and non-cerebral ischemic vascular events, major intracerebral and extracerebral bleeding and vascular death in 401 consecutive patients with ischemic stroke or TIA and atrial fibrillation who were discharged with oral anticoagulation (OAC), antiplatelet agents (AA), or heparin only in a clinical routine setting. The median follow-up time was 25 (interquartile range (IQR): 15-38) months.
