摘要:
目的 探讨经冠状动脉血栓抽吸导管在闭塞冠脉远段给予替罗非班、肝素及造影剂对伴高血栓负荷的急性心肌梗死(STEMI)的安全性和有效性。 方法 2018年7月至2019年10月连续入院并进行急诊介入干预的急性STEMI患者376例,根据临床最终处理方法分为对照组(常规支架及血栓抽吸,n = 322例)和研究组(抽吸导管闭塞血管远段处理,n = 54例)。比较两组术后术后心肌水平再灌注情况(TIMI血流分级)、围手术期出血事件,住院期间死亡,脑卒中,心肌梗死等主要不良心血管事件发生情况。 结果 研究组较对照组术后TIMI血流3级率无显著性差异(95.3% vs 96.3%,P > 0.05)。两组再灌注心律失常、低血压、心室颤动发生率均无显著性差异(P > 0.05),两组远端血管分支栓塞、无复流的发生率均无显著性差异(P > 0.05),两组围手术期大出血发生率无显著性差异(P > 0.05)。两组均无脑卒中事件发生,两组MACE事件无显著性差异(7.7% vs 11.1%,P > 0.05)。两组发生急性心衰无显著性差异(6.8% vs 7.4%,P > 0.05)。 结论 经血栓抽吸导管在闭塞血管远段给予抗栓及造影法对伴高血栓负荷的急性STEMI患者可有效改善心肌水平的灌注,降低围手术期的风险,值得进一步深入研究。 Abstract:Objective To the investigate the safety and efficacy of reverse use tirofiban and contrast agent through thrombus suction catheter after occlusion artery route in hyperthrombotic load patients with acute myocardial infarction. Methods From July 2018 to October 2019, 376 acute STEMI patients treated by emergency percutaus coronary intervention were admitted to the hospital successively. According to the different treatment methods, the 376 acute STEMI patients were divided into the study group (n = 54) and the control group (n = 322). The effects of two different routes of administration on postoperative myocardial perfusion(TIMI flow grades) and the incidence of severe hemorrhage, stroke and serious cardiac adverse events during hospitalization were compared. Results The preoperative thrombotic load of the study group was significantly higher than that of the control group (3.23±0.95 vs 2.14±0.66, P < 0.05). There was no significant difference in the incidence of intraoperative complications (P > 0.05), and there was no significant difference in the postoperative rate of TIMI 3 between the two groups (95.3% vs 96.3, P > 0.05). There was no significant infference to the incidence of severe hemorrhage, stroke during PCI and serious cardiac adverse events during the hospitalization between the two groups(P > 0.05). Conclusion With the use of tirofiban and contrast agent through thrombus suction catheter after the occlude artery route, it can effectively improve the myocardial perfusion and reduce the perioperative risk of acute STEMI patients with hyperthrombotic load and it is worthy of further study. -
