Groups were compared by independent t test. Values were expressed as mean±standard deviation. p<0.05 was accepted as statistically significant. P values less than 0.05 are in bold.

lat: lateral; SR: strain rate; VELsys: peak systolic myocardial velocity; VEL_E: peak early diastolic velocity; VEL_A: peak late diastolic myocardial velocity; SRsys: peak systolic SR (s⁻¹); SR_E: peak early diastolic SR; SR_A: late diastolic SR
