Abstract:
Objective To evaluate the early change of left ventricular (LV) systolic function in patients with type 2 diabetes mellitus(T2DM) by ultrasound speckle tracking imaging. Methods Ninety-five subjects were included:40 T2DM with normal LV ejection fraction (LVEF≥50% ,group A),20 T2DM with abnormal LVEF (LVEF<550 %) (group B), and 35 normal controls. Two-dimensional strain images were acquired from LV short-axis view. LV peak systolic global and segmental radial strain and circumferential strain at the levels of mitral annulus, papillary muscle and apex, and LV systolic global and segmental rotation at the levels of mitral annulus and apex and LV peak systolic global twist were assessed. Results In group A, compared with control group, LV peak systolic radial strain parameters were not significant difference (P >0.05), peak systolic circumferential strain of part segments, average peak strain of each plane and global strain were reduced (P <50.05～0.001) ,and LV peak systolic rotation of all apical segments, peak systolic global rotation at the levels of mitral annulus and apex,and peak systolic global twist were significantly increased (P <0.05～0.001). Compared with control group and group A,all LV systolic radial strain and circumferential strain parameters, LV systolic global and segmental rotation and peak systolic global twist in group B were significantly reduced (P <0.05 ～ 0.001). Conclusions Speckle tracking imaging could be used to evaluate the early change of LV torsional deformation and LV systolic function in T2DM.
