Abstract：Objective: To evaluate the left ventricular myocardial mechanical changes in patients with hypertension by two-dimensional strain technique. Methods: 169 patients with abnormal blood pressure in our hospital were divided into blood pressure rising group, hypertension stage 1 group, and hypertension stage 2 group, another 50 healthy persons with age and gender matching were selected as the control group. Two-dimensional echocardiography was performed. After routine measurement and image acquisition, EchoPAC software was used to analyze. The left ventricular global longitudinal endocardial strain (GLS-endo), global longitudinal midcardial strain(GLS-Mid), and global longitudinal epicardial strain(GLS-epi) were obtained. Results: Compared with the control group and the blood pressure rising group, the GLS-endo in hypertension stage 1 group were decreased, and the GLS-epi, GLS-Mid, and GLS-endo in hypertension stage 2 group were decreased, the differences were statistically significant(P<0.05). Compared with hypertension stage 1 group, GLS-epi, GLS-Mid, and GLS-endo were decreased in hypertension stage 2 group, and the differences were statistically significant(P<0.05). Conclusion: Layer-specific strain is a promising approach to evaluate left ventricular myocardial function in patients with hypertension at different blood pressure levels. It can detect the left ventricular myocardial mechanical damage in patients with hypertension at an early stage and has certain clinical application value.
