Real-time Three-dimensional Echocardiographic Assessment of Left Ventricular Remodeling Index in Patients with Hypertensive Heart Disease and Coronary Artery Disease

摘要

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 (P0.05), but significant difference in HHD and CAD intra-group (P0.05). 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.
