OBJECTIVE: To evaluate the clinical value of two-dimensional speckle tracking echocardiography for analyzing the left ventricular systolic function in @entity1 with @entity453 with normal wall motion (NWM-MVD). @entity1 AND METHODS: Forty-five NWM-MVD @entity1 and thirty-six subjects with low risk of @entity453 (control group) were enrolled in this study. Echocardiogram images of the short axis of the left ventricle and apical long axis were obtained. The Q-analysis software was used to analyze the peak systolic strain of the left @entity67 (GLS). We calculated the left ventricular global circumferential strain (GCS) and the radial strain (GRS), as well as the longitudinal, radial and circumferential strain of the basal (Bas-GLS, Bas-GCS, Bas-GRS), middle (Mid-GLS, Mid-GCS, Mid-GRS) and apical segments (Ap-GLS, Ap-GCS, Ap-GRS). RESULTS: (1) The @entity1563 or @entity432 were visible in 85.71% of the NWM-MVD @entity1 . (2) The heart rate of the NWM-MVD @entity1 was lower than that of the control group [(61.78    6.76) beats/min vs. (66.13    6.24) beats/min, p < 0.05]. The conventional ultrasonic measurement indices are similar between the NWM-MVD group and the control group (p > 0.05). (3) Compared with the control group, the GLS, Bas-GLS, Mid-GLS, Bas-GCS, Mid-GCS, GRS and Bas-GRS were lower in the NWM-MVD group (p < 0.05). CONCLUSIONS: The longitudinal, circumferential and radial systolic functions of the NWM-MVD @entity1 were impaired at different degrees.
