| 摘 要： | 冠状动脉粥样硬化性心脏病是常见的心血管疾病，严重危害身体健康。寻求无创的超声参数评价冠状动脉狭窄具有重要的临床意义。斑点追踪显像（STI）是评价心肌收缩功能的超声心动图新技术，不仅可用于评价心肌整体收缩能力，还可准确评价心肌各个节段的纵向应变、环向应变及径向应变。本文对斑点追踪显像技术在冠状动脉重度狭窄中的应用现状进行综述。

| Abstract: | Coronary atherosclerotic heart disease is one of the common cardiovascular diseases, which may result in serious consequences. It is important to find a noninvasive method to evaluate the stenosis degree of coronary artery. Speckle tracking imaging is a newly technique, which is widely used in evaluating myocardial systolic function. Speckle tracking imaging can be used to provide global and segmental longitudinal strain, circumferential strain and radial strain, which may predict the stenosis degree of coronary artery. The current status of application of speckle tracking imaging in evaluating severe coronary artery stenosis was reviewed in this article. |
