Abstract:
ObjectiveTo analyze the systolic function of subendocardial myocardium of the left ventricle in patients with diabetes mellitus (DM) and DM associated hypertension by speckle tracking imaging (STI).Methods The left ventricular ejection fraction(LVEF) and left ventricular mass index (LVMI) of all subjects including 30 patients with diabetes mellitus(DM group),25 patients with DM associated hypertension (DH group) and 30 healthy volunteers (control group) were normal and near.The common parameters of echocardiogram were measured and the peak systolic longitudinal strain of subendocardial myocardium were analyzed from the long-axis view at the levels of mitral annulus,papillary muscle and apex by STI.All above parameters were compared among three groups.ResultsNo significant difference in all parameters was found between the control group and two patient groups,but the ratio of E/A was significantly lower in the two patient groups than that of control group ( P ＜0.01).The peak systolic longitudinal strain of some segments were significantly lower in the two patient groups than that of control group ( P ＜0.01).The peak systolic longitudinal strain of the subendocardial myocardium of all segments in the two patient groups were different decrease compared with the control group( P ＜0.01 or P ＜ 0.001).The peak systolic longitudinal strain of the subendocardial myocardium of the DH group except some segments were decrease compared with the DM group ( P ＜0.01).ConclusionsSTI may be early used to identify the left ventricular systolic function in patients with diabetes mellitus.
