Apixaban For The Reduction Of Thrombo-Embolism In Patients With Device-Detected Sub-Clinical Atrial Fibrillation
This study is a prospective multicenter double-blind randomized controlled trial. It will recruit patients with SCAF (Sub-Clinical Atrial Fibrillation) detected by either a pacemaker, an ICD (implantable cardioverter defibrillator) or an insertable cardiac monitor (ICM); who also have other risk factors for stroke (previous stroke/TIA or systemic arterial embolism OR age ? 75 OR age 65-74 with ? 2 other risk factors OR age 55-64 with ? 3 other risk factors). Eligible and consenting patients will be randomized to receive aspirin or apixaban. The primary efficacy outcome is the composite of stroke and systemic arterial embolism. A total of 4000 patients will be enrolled from 70 or more clinical centers, with an anticipated mean follow-up of at least 36 months, with the precise termination of follow-up occurring once 248 verified/adjudicated primary efficacy outcome events have occurred.
