摘要
Abstract
Objective:To assess the change of left ventricular inner-half layer myocardium strain in primary hypertension pa-tients using two-dimensional speckle tracking imaging,to investigate its change regulation and clinical significance. Methods:We chose 73 patients with primary hypertension,then divided them into two groups due to the left ventricular mass index (LVMI), one group was 33 cases without left ventricular hypertrophy (NH),the other group was 40 cases with left ventricular concentric hypertrophy (CH). And then chose 40 volunteers as control group. Use two-dimensional speckle tracking imaging to record the global peak systolic longitudinal strain of the whole layer myocardium (GLPSSa) and the inner-half layer myocadium (GLPSSi),the global peak systolic radial strain of the whole layer myocardium (GRPSSa) and the inner-half layer myocadium (GRPSSi). Results:Compared with the control group,the GLPSSa、GLPSSi of NH and CH group decreased and had statistical significance (P<0.05). Compared with the control group,the GRPSSa of NH group increased but had no statistical significance (P>0.05),but the GRPSSi of NH group significantly increased and had statistical significance (P<0.01). The GRPSSa and GRPSSi of CH group were both significantly decreased and had statistical significance (P<0.01). Conclusion:Two-dimensional speckle tracking imaging can assess the change of left ventricular inner-half layer myocardial strain in different degrees of pri-mary hypertension patients accurately and objectively .The systolic function of left ventricular inner-half layer myocardial changes earlier than the whole layer myocardium.关键词
