Echocardiographic Risk Factors for Stroke and Outcomes in Patients With Atrial Fibrillation Anticoagulated With Apixaban or Warfarin

摘要

Background and Purpose-Few data exist on the long-term outcomes of patients with spontaneous echo contrast (SEC), left atrial/left atrial appendage (LA/LAA) thrombus, and complex aortic plaque (CAP), in patients with atrial fibrillation receiving oral anticoagulation. We explored the relationship between these 3 echocardiographic findings and clinical outcomes, and the comparative efficacy and safety of apixaban and warfarin for each finding.
