Title: The effects of adequate left ventricular mass and inappropriately high left ventricular mass on left ventricular structure and function in essential hypertension
Abstract: Objective:The ratio of observed/predicted left ventricular mass (%PLM) divides left ventricular remodeling into adequate left ventricular mass (aLVM), inappropriately high left ventricular mass (iLVM), and inadequate left ventricular mass. Then, investigation and comparation of left ventricular structure and function between aLVM and iLVM. Methods:Left ventricular geometry and cardiac function are assessed by echocardiography in 187 cases of essential hypertension. Results:In this study, 48.1 % had aLVM, 48.7 % had iLVM, 3.2 % had inadequate LVM. In comparison with aLVM, aortic root dimension? left atrial dimension? left ventricular mass (LVM) and relative wall thickness (RWT) were higher (P 0.05 ), while cardiac output?stroke volume? ejection fraction (EF)? fractional shortening (FS), and E/A ratio were lower (P 0.05 ), and total peripheral resistance (TPR) was higher (P 0.05 ) in subjects with iLVM. Conclusion:Compared with aLVM, iLVM was a more developing stage of left ventricular remodeling.
