    Usefulness of two-dimensional strain echocardiography for evaluation of left ventricular diastolic function in diabetes mellitus

    • 摘要: 目的:探讨二维应变超声心动图(2-DSE)评价2型糖尿病(diabetes mellitus,DM)患者早期DM心肌病左心室舒张功能障碍的价值。方法:分别选取无高血压、冠心病及其他心脏病变的DM患者29例和健康人30名(对照组)。应用基于多普勒组织应变率成像和2-DSE获得左心室6个壁中间和基底段纵向舒张早期峰值应变率(SRe)及晚期应变率(SRa),并计算SRe/SRa;彩色多普勒常规测量二尖瓣口舒张早期最大血流速度(E)、二尖瓣口舒张晚期最大血流速度(A)及E/A;比较2组的测量结果。结果:DM组舒张期E峰、E/A、SRe、SRe/SRa较对照组明显减低(P < 0.01),2组左心室各节段SRe及SRe/SRa差异有统计学意义。结论:2-DSE能准确地定量测定DM患者左心室整体和局部心肌的应变率,发现早期DM心肌病左心室舒张功能障碍。

       

      Abstract: Objective: To evaluate diastole function of left ventricular in early diabetic cardiomyopathy by two-dimensional strain echocardiography (2-DSE). Methods: Twenty-nine diabetic patients and 30 healthy people were chosed,strain rate based on Doppler tissue imaging and 2-DSE were performed on DM and healthy subjects at apical long axis,two-chamber and four-chamber views. The following parameters were analyzed in basal and middle segments (all in longitudinal direction only):early diastolic strain rate (SRe), late diastolic strain rate (SRa) and the ratio of SRe/SRa; mitral Doppler inflow were analyzed and E/A ratio were calculated. The results were compared. Results: Compared with healthy subjects,the parameters of E,E/A,SRe,SRe/Sra,in DM decreased significantly (P < 0.01),there was a significant difference in those parameters of SRe,SRe/SRa between two groups. Conclusions: 2-DSE is a new simple,rapid,angle-independent and reproducible method to assess global and regional left ventricular myocardial diastole function quanlitification. It can assess early left ventricular diastolic dysfunction in diabetic cardiomyopathy.
