Conclusions Combining stain rate and DSE to quantify local myocardial motion is valuable to offer many important clinical messages, and improves the diagnosis of coronary heart disease.
结论DSE与应变率结合定量评价局部心肌运动为临床诊断冠心病提供了有价值的信息。
The sensitivity and specificity of SRI with DSE for detecting ischemic myocardium were (90.0) % and (91.7) %, respectively.
应变率检测缺血节段的敏感性和特异性分别为90.0%和91.7%。
Conclusions PW DTI combined with high dose DSE can correctly evaluate left ventricular regional systolic function of long axis and detect ischemic myocardium.
