摘　　要：目的探讨二维斑点追踪显像(2DSTI)技术评价肥厚心肌的左心室功能的价值。方法选择正常对照组30例,高血压心肌肥厚组30例,糖尿病心肌肥厚组30例。应用STI技术测定左心室各壁基底段、中间段和心尖段收缩期峰值应变(Ls),并对检测结果进行分析。结果与对照组相比,高血压心肌肥厚组与糖尿病心肌肥厚组的心肌纵向应变值在左室基底段和中间段、心尖段均较对照组低(P<0.05)。与糖尿病心肌肥厚组比较,高血压合并心肌肥厚组在左室基底段、中间段和心尖段的纵向应变值差异无统计学意义(P>0.05)。结论应用二维斑点追踪显像技术测量收缩期左室径向应变值,可以了解心肌收缩时径向运动和应变值的变化,有助于判断和评价局部心肌功能。Objective To evaluate the left ventricular function of left ventricular hypertrophy using two-dimensional speckle tracking imaging.Methods Thirty cases of the control group,30 cases of hypertension heart group,and 30 cases of diabetic cardiomyopathy were selected,Using speckle tracking imaging,systolic peak strain（Ss）were measured at basal,middle and apical segments,and the results were analyzed.Results Compare to control group,the Ss in hypertension heart group and diabetic cardiomyopathy group were lower（P〈0.05）.The difference of Ss between hypertension heart group and diabetic cardiomyopathy group was not statistically significant（P〉0.05）.Conclusion STI conduces to understand the changes in radial motion and peak strain in myocardial contraction time,and it conduces to analyze and evaluate regional myocardial function.
