  1. Values are expressed as means ± SE for each group. LA left atrium, RA right atrium, LV left ventricle, EDD end diastolic dimension, ESD end systolic dimension, PW posterior wall thickness of LV, IVS intra-ventricular septum, EF ejection fraction of LV, FS fractional shortening of LV, E mitral Doppler E peak velocity, A mitral Doppler A peak velocity, IVRT isovolumetric relaxation time, IVCT isovolumetric contraction time. Statistical significance was determined by ANOVA followed by post hoc Newman-Keuls (SNK) tests
