Abstract:
BACKGROUND:Left ventricle volume or volume index and left ventricle mass or mass index are commonly used to evaluate left ventricle remodeling. Recently,real-time three dimensional echocardiography (RT3DE) has been attempted to evaluate left ventricle remodeling index (LVRI),and it is believed that LVRI can serve as new index to evaluate left ventricle reconstruction clinically. OBJECTIVE:To assess application of RT-3DE in evaluating left ventricular remodeling in patients with hypertension. DESIGN,TIME AND SETTING:Case-control observation was performed at the Department of Ultrasonography,First Hospital of Liaoning Medical University from September 2008 to September 2009. PARTICIPANTS:A total of 90 hypertension patients and 30 normal people were selected. The hypertension patients were divided into 3 subgroups according to interventricular septum,left ventricle myocardial thickness and end-diastolic diameter:normal configuration,concentric hypertrophy and eccentric hypertrophy groups with 30 cases in each group. METHODS:Three dimensional echocardiography of 90 patients and 30 controls was performed. Left ventricular end-diastolic volume (EDV),left ventricular end-diastolic epicardial volume (EDVepi) were measured by RT-3DE; left ventricular mass (LVM),left ventricular mass index (LVMI),left ventricular end-diastolic epicardial volume index (EDVI),LVRI were calculated and compared with two-dimensional echocardiography (2DE) Simpson biplane method. MAIN OUTCOME MEASURES:LVRI,LVMI,and EDVI detected by RT-3DE and 2DE Simpson biplane. RESULTS:LVRI,EDVI,LVMI measured by RT-3DE and 2DE were significantly different in hypertension patients (P 0.05). The LVRI measured by RT-3DE,2DE and EDVI,LVMI measured by 2DE were significantly correlated in normal control,normal configuration and concentric hypertrophy group (P 0.05). CONCLUSION:Real-time three-echocardiographic LVRI can serve as a new approach for evaluating left ventricular remodeling in clinic.
