超声斑点追踪在2型糖尿病患者心脏局部收缩功能评价中的作用

目的：探讨超声斑点追踪技术对2型糖尿病患者心脏局部收缩功能评价中的作用。方法选择2013年1～12月在我院诊治的2型糖尿病患者45例为研究组，以及在我院健康体检者40例为对照组。比较两组超声半点追踪成像技术检测结果。结果研究组基底段、中段、心尖段以及整体左室收缩期纵向应变值均显著低于对照组（P＜0.01）。研究组二尖瓣水平、乳头肌水平、心尖水平以及整体左室收缩期径向应变值均显高低于对照组（P＜0.01）。结论超声斑点追踪技术是评价2型糖尿病患者心脏局部收缩功能无创的方法，能够早期发现糖尿病患者的亚临床心肌病变。

The role of ultrasound speckle tracking for evaluating cardiac systolic function in type 2 diabetic patients

ObjectiveTo discuss the role of ultrasound speckle tracking for evaluating cardiac systolic function in type 2 diabetic patients.Methods 45 cases with type 2 diabetic from January to December 2013 were selected as study group, and 40 healthy volunteers were selected as control group.Results of ultrasound speckle tracking of two groups were compared. Results Systolic longitudinal strain values of basal, middle and apical segments and overall LV of study group were lower than control group（P〈0.01）. Systolic radial strain values of mitral valve level, papillary muscle level, apical level and overall LV of study group were higher than control group（P〈0.01）.Conclusion Ultrasound speckle tracking for evaluating cardiac systolic function in type 2 diabetic patients is noninvasive methods, which can early diagnosis diabetic patients with subclinical cardiomyopathy.
