急性心肌梗死患者直接PCI后的心电图ST段回落分析

Analysis of ST-segment Resolution Following Primary PCI in the Patients with Acute Myocardial Infarction

目的:联合应用TIMI心肌灌注分级(TMP)、心电图ST段变化(sumSTR)方法评价急性心肌梗死(AMI)急诊经皮冠状动脉介入治疗(PCI)后心肌灌注程度。方法:连续入选57例AMI患者,按梗死部位分为前壁组和下壁组,于6h～12h内行直接PCI,并于手术前后分别记录ST段变化和TMP变化,从而评价心肌灌注程度。结果:对比57例AMI患者PCI前后记录显示,术后ST段明显回落TMP数值上升。结论:PCI对AMI患者疗效显著。

Objective To assess the extent of perfusion of acute myocardial infarction （AMI） undergoing percutaneous coronary intervention （PCI） by use of TIMI Myocardial perfusion and sum-ST-segment resolution. Methods A total of 57 consecutive acute myocardial infarction patients with ST-segment elevation were divided into two groups： anterior wall and inferior wall,all the patients undergoing PCI within 6 h - 12 h,the ST-segment elevation and TIMI myocardial perfusion （TMP） of 57 patients with AMI before PCI and after PCI were recorded. Results Compared with before PCI , the ST-segment elevation of the patients after PCI was low, TMPG（TIMI myocardial perfusion grades）was high. Conclusion Percutaneous coronary intervention has significant effects in patients with AMI.
