摘　　要：目的探讨双多普勒同步取样技术评估不同程度T2DM患者左室舒张功能的研究。方法随机选取60例T2DM患者,分为无微血管病变组32例(A组)、有微血管病变组28例(B组)和健康人60例作为正常对照组(C组)。应用传统取样方法和双同步技术分别测量E/Vp、E/eL′(侧壁)、E/eS′(室间隔),比较三组间各个参数的差异。结果 (1)在存储和分析图像所用时间上双同步技术明显短于传统取样方法(P<0.05);(2)组内相关系数(ICC)及Bland-Altman分析显示双同步技术较传统取样方法测量E/Vp、E/e′L、E/e′S重复性更佳;(3)与C组比较,A、B组E/Vp、E/e′L、E/e′S均增高(P<0.05)。与A组比较,B组E/Vp、E/e′L、E/e′S明显增高(P<0.05)。结论双多普勒同步技术较传统取样方法更简便、快捷、准确地评估糖尿病患者的早期左室舒张功能。Objective To evaluate dual-Doppler technology in assessing the left ventricular diastolic fuction in type 2diabetes mellitus patients（T2DM）in different degress.Methods 60 patients with T2 DM were randomly selected and divided into two groups：without microangiopathy（n=32）and with microangiopathy（n=28）.And 60 volunteers were randomly selected as control（n=60）.Using traditional technology and dual-doppler technology to measure E/A,E/Vp,E/eL′,E/eS′,respectively.Compare the differences between the four groups.Results（1）Time of image store and analysis of synchronous measurement were significantly shorter than traditional methods（P〈0.05）.（2）ICC and Bland-Altman analys is showed that E/eL′,E/eS′and E/Vp measured by the dual-Doppler modality had better reproducibility.（3）Compared with group C,E/Vp,E/eL′,E/eS′of group A and B increased significantly（P〈0.05）;Compared with group A,E/Vp,E/eL′,E/eS′of group B increased obviously.Conclusions The dualDoppler technology is more simple,quick and accurate than conventional Doppler modality to assess the left ventricular diastolic function in T2 DM with different degree.
