Data obtained from Spearman’s correlation analysis are shown in the table. A wave-peak atrial filling (A) velocity; DBP - diastolic blood pressure; E wave - peak early filling velocity; IVRT - isovolumic relaxation time; Lat/sep e’ - mean of lateral and septal peak early diastolic velocities; LAVI - left atrial volume index; MDT - deceleration time of E wave; MPI - myocardial performance index; s’ - peak systolic annular velocity; SBP - systolic blood pressure
