Abstract

Objective: To observe the rotation parameter of left ventricular short-axis views in the subendocardial and subepicardial myocardium layers by two-dimensional speckle tracking imaging(2DSTl), and to evaluate its performance in patients with type 2 diabetes mellitus(T2DM)． Methods: Fourty-three patients with T2DM(20 patients without microangiopathy, 23 patients with microangiopathy), and 30 cases of healthy volunteers as control were included in the study． High frame rate dynamic two-dimensional images were recorded at the left ventricular short-axis view, including basal and apical planes． The peak subendocardial rotation(Prot-endo), peak subepicardial rotation(Prot-epi), peak bulk rotation(Prot), and peak mural rotation(Prot-mur) were measured． Results: ①The apical Prot-endo, Prot-epi, Prot and the basal Prot-epi were higher and the apical Prot-mur was lower in control group than the T2DM group with microangiopathy(P＜0.05). ②The basal Prot-endo of T2DM patients with microangiopathy was significantly lower than that in control group. ③When compared to the control group, the basal Prot-mur decreased while the basal Prot increased in the T2DM group(P＜0.05)． Conclusions: The 2DSTI can accurately evaluate the characteristics of left ventricular rotation parameter and sensitively evaluate the cardiac function in patients with T2DM.
