摘　　要：目的探讨速度向量成像技术（VVI）评估2型糖尿病患者心肌舒张功能的临床价值。方法选择2012年2月～2014年6月期间治疗的52例2型糖尿病患者作为研究对象，并分为A组（无微血管病变组，n=25例）和B组（微血管病变组，n=27例），同时选择25例健康体检者作为对照组。采用VVI检测各组舒张早期峰值速度（Ve）、应变率（SRe）。结果B组E峰及E／A明显低于对照组（P〈0．05），而A峰明显高于对照组（P〈0．05）；A组基底后壁，中部前壁、侧壁和后壁，心尖侧壁等节段的舒张早期Ve值明显低于对照组（P〈0．05）；而B组除了中部后壁、下壁和后间隔，心尖部室间隔以外节段的舒张早期Ve值明显低于对照组（P〈0．05）；A组除了基底及中部侧壁、中部前间隔以外节段的舒张早期SRe值明显低于对照组（P〈0．05），B组除了中部前间隔以外节段的舒张早期SRe值明显低于对照组（P〈0．05）。两组仅基底部前壁及后间隔在SRe值比较有显著差异性（P〈0．05），而各节段在Ve值比较差异无统计学意义（P〉0．05）。结论VVI技术对评估2型糖尿病患者心肌舒张功能具有一定的临床价值。Objective To explore the clinical value of velocity vector imaging （VVI） in the evaluation of myocardial dias- tolic function of patients with type 2 diabetes. Methods 52 cases of patients with type 2 diabetes treatment from February 2012 to June 2014 were chosen as the research object. Patients were divided into A group （without microvascular lesion group, n=25 cases） and B group（microvascular lesion group, n=27 cases）. At the same time 25 health physical examina- tion were select as control group. The early diastolic peak velocity （Ve） and strain rate （SRe） of three groups were tested by VVI. Results The E peak and E/A of B group was significantly lower than that of the control group（P〈0.05）. While A peak was significantly higher than that of the control group（P〈0.05）. The early diastolic Ve value of A group in basement wall, after the central front wall, lateral wall and back wall, lateral wall was lower than that of the control group（P〈0.05）. The early diastolic Ve value of B group in addition to the central and back wall, the wall after the inter- val, apex of ventricular septal outside segment was lower than that control group （P〈0.05）. The early diastolic SRe value of A group in addition to the basal and middle wall, before the interval in segment was lower than that of the control group（P〈0.05）. The early diastolic SRe value of B group in addition to interval before the central segment was lower than that of control group（P〈0.05）. There was a significant difference between A group and B group about the SRe value in addition to the base wall before and after the interval（P〈0.05）. The value of Ve in each segment had no statis- tically significant difference（P〉0.05）. Conclusion VVI technique has a certain clinical value to assess the myocardial diastolic function of patients with type 2 diabetes.
