  • Data are presented as mean±SD

  • LVEF: left ventricular ejection fraction

  • LVPER: left ventricular peak emptying rate

  • LVED: left ventricular end-diastolic volume

  • TPER: time to peak emptying rate

  • LVPFR: left ventricular peak filling rate

  • TPFR: time to peak filling rate

  • s/d: systolic/diastolic

  • ns: nonsignificant
