Incidence and predictors of left atrial thrombus in patients with atrial fibrillation under anticoagulation therapy

Left atrial thrombus (LAT) formation is associated with thromboembolic events. To investigate the incidence and associated factors of LAT in patients with atrial fibrillation (AF) who had been receiving anticoagulation therapy for more than 4 weeks, and to develop a prediction model using clinical and echocardiographic features. Medical records of 1,122 patients with AF (mean age, 59.4 ± 11.0 years, 58.3
