IVSTd, interventricular septal thickness in diastole; LASr, left atrial strain during reservoir phase; LAVI, left atrial volume index; LVEF, left ventricular ejection fraction; LV‐GLS, left ventricular global longitudinal strain; LVPWTd, left ventricular posterior wall thickness in diastole; pLASRcd, peak strain rate during conduit phase; pLASRct, peak strain rate during contraction phase; pLASRr, peak strain rate during reservoir phase; RapLSI, relative apical longitudinal strain index; TRPG, transtricuspid pressure gradient.
P‐value was obtained by using Pearson's method.
