Independent and incremental value of LASr at identifying athletes with AF on top of clinical characteristics (CHA₂DS₂-VASc score, height, and weight) and standard echocardiographic parameters (E/e′, mitral inflow velocity and mitral annular early diastolic velocity; GLS, global longitudinal strain; LAVI_max, maximal left atrial volume indexed; LVMI, left ventricular mass index) in a hierarchical logistic regression model.
