超声心动图评价冠状动脉慢血流现象的研究进展

冠状动脉慢血流现象（CSFP）指通过冠状动脉造影发现冠状动脉末梢灌注延迟，但无明显的冠状动脉病变。多数患者并无心脏结构及收缩功能异常，但可能出现胸痛症状反复发作，严重影响患者的生活质量。因此，以简便、无创、安全的检查手段确诊并评估CSFP尤为重要。随着近年超声心动图的发展，通过常规超声、二维及三维斑点追踪成像及心肌CEUS等多种超声技术均可对CSFP进行定性、定量分析。本文对超声心动图评价CSFP的研究进展进行综述。

Progresses of echocardiography in evaluating coronary slow flow phenomenon

Coronary slow flow phenomenon (CSFP) is an angiographic diagnosis characterized by delayed peripheral coronary perfusion in the absence of significant epicardial coronary lesions. Cardiac structure and systolic function of most patients had no abnormality, but there might be recurrent chest pain with impairment in quality of life. Therefore, it is very important to diagnose and assess CSFP using noninvasive, easy and safe technique. With the development of echocardiography in recent years, CSPF can be quantitatively and qualitatively analyzed with conventional echocardiography,two-dimensional and three-dimensional speckle tracking echocardiography and myocardial contrast echocardiography. Progresses of echocardiography in evaluating CSFP were reviewed in this article.
