Objective To discuss the quantitive evaluation of left ventricular remodeling in patients with AMI after CABG by using RT-3DE.Methods Data of 33 patients with AMI after CABG were acquired by using RT-3DE.The left ventricule end diastolic volume(LVEDV),1eft ventricule end systolic volumeLV(ESV),stroke volume(SV),ejection fraction(EF) and mass index of 1eft ventricule were measured before CABG,one week,one year after CABG,and made comparative analysis,and compared with those of the control group as well.Results The LVEDV,LVESV and 1eft ventricular mass index(LVMI) in patients with AMI were significantly higher before CABG than those in the normal control group(P0.05),and LVEF was significantly lowered(P0.05);one week after CABG,the LVEDV,LVESV and 1eft ventricular mass index(LVMI) in patients with AMI were high compared with those before CABG(P﹥0.05) and LVEF was lower(P﹥0.05);one year after CABG,the LVEDV,LVESV and 1eft ventricular mass index(LVMI) in patients with AMI were significantly lower than those before CABG(P0.05),and LVEF was significantly higher(P0.05).Conclusions Coronary artery bypass grafting can reverse left ventricular remodeling,which can be quantitively evaluated by RT-3DE.
