摘　　要：目的探讨三维斑点追踪成像(3D-STI)评估2型糖尿病(T2DM)伴腹型肥胖患者左心室心肌收缩功能的价值。方法收集56例T2DM患者,其中腹型肥胖组26例、无腹型肥胖组30例,以30名健康体检者为对照组。比较3组常规超声参数左心室舒张末期内径(LVDd)、二维射血分数(2D-EF)、相对室壁厚度(RWT)、左心室舒张末期容积(LVEDV)、左心室收缩末期容积(LVESV)、三维射血分数(3D-EF)以及应变参数左心室整体纵向应变(LVGLS)、左心室整体圆周应变(LVGCS)、左心室整体面积应变(LVGAS)、左心室整体径向应变(LVGRS)。结果常规超声参数及应变参数比较,腹型肥胖组LVDd、RWT、LVEDV、LVESV均较对照组、无腹型肥胖组升高(P均<0.05),2D-EF、3D-EF均低于对照组(P均<0.05)。腹型肥胖组、无腹型肥胖组LVGLS、LVGCS、LVGAS、LVGRS均较对照组减低(P均<0.05),且腹型肥胖组均低于无腹型肥胖组(P均<0.05)。结论 3D-STI可用于评估T2DM伴腹型肥胖患者左心室心肌收缩功能。Objective To evaluate left ventricular myocardial systolic function in patients with type 2 diabetes mellitus(T2 DM) combined with abdominal obesity with three-dimensional speckle tracking imaging(3 D-STI). Methods A total of 56 T2 DM patients were enrolled, including 26 patients with abdominal obesity(abdominal obesity group) and 30 without abdominal obesity(non-abdominal obesity group), while 30 healthy volunteers were selected as the control group. Conventional ultrasound parameters and strain parameters, including left ventricular end-diastolic diameter(LVDd), two-dimensional ejection fraction(2 D-EF), relative wall thickness(RWT), left ventricular end-diastolic volume(LVEDV), left ventricular end-systolic volume(LVESV), three-dimensional ejection fraction(3 D-EF), as well as left ventricular global longitudinal strain(LVGLS), left ventricular global circumferential strain(LVGCS), left ventricular global area strain(LVGAS) and left ventricular global radial strain(LVGRS) were compared among 3 groups. Results Among the three groups, LVDd, RWT, LVEDV and LVESV in abdominal obesity group were higher than those in control group and non-abdominal obesity group(all P<0.05), while 2 D-EF and 3 D-EF were lower than those in control group(both P<0.05). LVGLS, LVGCS, LVGAS and LVGRS in abdominal obesity group and non-abdominal obesity group were lower than those in control group(all P<0.05), while in abdominal obesity group were lower than in non-abdominal obesity group(all P<0.05). Conclusion 3 D-STI can be used to evaluate left ventricular myocardial systolic function in patients with T2 DM combined with abdominal obesity.
