Abstract:
Objective To assess the short-axis and long-axis systolic function of the left ventricle (LV) in patients with type 2 diabetes mellitus and without coronary artery disease using two-dimensional strain echocardiography.Methods Eighty-nine subjects with normal ejection fraction were included:37 with diabetes mellitus(DM group),22 with both diabetes and left ventricular hypertrophy(DH group), and 30 normal controls.Two-dimensional strain images were acquired from the LV short-axis view at the levels of mitral annulus, papillary muscle and apex, and the apical four-chamber view, two-chamber view and long-axis views of the LV respectively.The longitudinal strain was measured in the apical views.The radial strain and the rotation were measured in the LV short-axis views.The LV twist was defined as the apical rotation relative to the base.Results The average peak systolic longitudinal strain of different segments and the peak longitudinal global strain in DM group and DH group were significantly reduced when compared with those in control groups ( P<0.001 ),and these parameters in DH group were significantly lower than those in DM group (P<0.001 or P<0.05).There was no significant difference in the average peak systolic radial strain of different segments and peak radial global strain among all groups ( P>0.05).The LV rotations and the LV twist were significantly higher both in DM group and in DH group than in control group ( P<0.001 or P<0.01),and the basal LV rotation and the LV twist were larger in DH group than in DM group ( P<0.01, P<0.05).Conclusions Two-dimensional strain echocardiography may be used to identify the LV systolic function in patients with type 2 diabetes mellitus.
