Abstract:
Objective To explore left ventricular remodeling index(LVRI),systolic function and their correlation by real-time three-dimensional echocardiography(RT-3DE)in patients with coronary artery disease(CAD).Methods According to coronary artery angiography,one main vessel stenosis no less than 50% was defined as positive standard,RT-3DE data of 24 patients with left circumflex coronary artery or/and right coronary artery stenosis(LCA/RCA group),21 patients with left anterior descending coronary artery stenosis(LAD group),27 patients with double or triplex coronary arteries stenosis which must included LAD(vessels group)and 22 normal controls(NC group)were acquired.Left ventricular end-diastolic volume(EDV),left ventricular end-diastolic epicardial volume(EDVepi),left ventricular ejection fraction(EF)were automatically measured by RT-3DE analysis software;left ventricular mass[1.05×(EDVepi-EDV)],LVRI(left ventricular mass/EDV)were calculated.The inter-group differences of LVRI,EF and intra-group correlations between LVRI and EF were analyzed.Results LVRI and EF significantly decreased in order(P＜0.05 or P＜0.01);and their correlation coefficents were r=0.10(P＞0.05),0.86(P＜0.01),0.83(P＜0.01)and 0.77(P＜0.01)in NC group,LCA/RCA group,LAD group,vessels group,respectively.Conclusions LVRI measured by RT-3DE can assess left ventricular remodeling,and reflect left ventricular systolic function in different CAD,which can be as a new approach for evaluating left ventricular remodeling in clinic.
