Real-time Three-dimensional Echocardiographic Assessment of Left Ventricular Remodeling Index in Patients with Hypertensive Heart Disease and Coronary Artery Disease / 华中科技大学学报（医学）（英德文版）

ABSTRACT

Left ventricular remodeling index (LVRI) was assessed in patients with hypertensive heart disease (HHD) and coronary artery disease (CAD) by real-time three-dimensional echocardi-ography (RT3DE).RT3DE data of 18 patients with HHD,20 patients with CAD and 22 normal con-trols (NC) were acquired.Left ventricular end-diastolic volume (EDV) and left ventricular end-diastolic epicardial volume (EDVepi) were detected by RT3DE and two-dimensional echocar-diography Simpson biplane method (2DE).LVRI (left ventricular mass/EDV) was calculated and compared.The results showed that LVRI measurements detected by RT3DE and 2DE showed sig-nificant differences inter-groups (P<0.01).There was no significant difference in NC group (P>0.05),but significant difference in HHD and CAD intra-group (P<0.05).There was good positive correla-tions between LVRI detected by RT3DE and 2DE in NC and HHD groups (r=0.69,P<0.01; r=0.68,P<0.01),but no significant correlation in CAD group (r=0.30,P>0.05).It was concluded that LVRI derived from RT3DE as a new index for evaluating left ventricular remodeling can provide more su-periority to LVRI derived from 2DE.
