This study aims to determine if treatment with apixaban, compared with aspirin, will reduce the risk of schemic stroke and systemic embolism in patients with device-detected sub-clinical atrial fibrillation (SCAF) and additional risk factors for stroke.
Who may be Eligible
Patients with a permanent pacemaker or defibrillator or insertable cardiac monitor capable of detecting SCAF, with at least one episode of SCAF lasting at least 6 minutes but not more than 24 hours.
