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 investigate the simultaneous assessment of left ventricular diastolic function in patients with T2DM by simultaneous dual-Doppler sampling. Methods Sixty T2DM patients were randomly divided into two groups: group A without macroangiopathy (group A), group with microangiopathy (group B) and group B with normal control (group C). The E / Vp, E / eL ’(sidewalls) and E / eS’ (interventricular septum) were measured by traditional sampling method and double synchronization technique respectively. Results (1) The double-synchronization technique was significantly shorter than the traditional sampling method (P <0.05) in the storage and analysis of images. (2) ICC and Bland-Altman analysis showed that the double-synchronization technique was more effective than the traditional sampling method The repeatabilities of E / Vp, E / e’L and E / e’S were better than those of group C; (3) Compared with group C, E / Vp, E / e’L, (P <0.05). Compared with group A, E / Vp, E / e’L and E / e’S in group B were significantly increased (P <0.05). Conclusion Double-Doppler synchronization technology is more convenient, faster and more accurate than the traditional sampling method to assess the early diastolic function of diabetics.
