目的探讨经胸超声心动图(TTE)在急诊冠状动脉介入术(PCI)的应用及其价值。方法92例胸痛患者,临床怀疑急性心肌梗死(AMI),在行急诊冠状动脉造影(CAG)之前,采用TTE从不同切面和角度,探测观察有无节段性室壁运动异常(RWMA)及其范围。对行急诊PCI的患者,术后定期复查,观察RWMA范围的变化及改善程度。结果TTE检查提示,89例存在RWMA,经急诊CAG均证实其相关冠状动脉完全或不完全闭塞,符合率100%,且其RWMA的区域与相关冠状动脉闭塞的部位及闭塞程度也明显相关。结论TTE可作为AMI诊断的可靠指标之一,也是选择适合患者作CAG、PCI以及评价急诊PCI后治疗效果的一个重要依据。
Objective To investigate the application and value of transthoracic echocardiography (TTE) in emergency percutaneous coronary intervention (PCI). Methods Ninety-two patients with chest pain were enrolled in this study. Patients with acute myocardial infarction (AMI) were enrolled in this study. Prior to emergency coronary angiography (CAG), TTE was used to detect the presence or absence of segmental wall motion abnormalities (RWMA) range. The patients undergoing emergency PCI were regularly reviewed to observe the extent of RWMA changes and improvement. Results The TTE examination showed that RWMA was present in 89 cases and the complete or incomplete occlusion of coronary arteries was confirmed by emergency CAG. The coincidence rate was 100%, and the RWMA region was also significantly correlated with the occlusion site and degree of occlusion of coronary arteries. Conclusions TTE can be used as one of the reliable indicators for the diagnosis of AMI. It is also an important basis for selecting suitable patients for CAG, PCI and evaluating the therapeutic effect after emergency PCI.
