目的评价血栓抽吸导管在急性心肌梗死(AMI)行急诊经皮冠状动脉介入治疗(PCI)中应用的有效性。方法选择急诊PCI冠状动脉造影后见血栓影的AMI患者40例,分为抽吸组21例,用ThrombusterⅡ血栓抽吸导管行冠状动脉内血栓抽吸,然后行PCI术;对照组19例,不进行抽吸治疗,按常规行PCI术。比较两组患者近期疗效及安全性。结果 PCI术后,抽吸组心肌梗死溶栓治疗试验(TIMI)血流达3级率高于对照组(95.24%vs.68.42%)(P<0.05),抽吸组术后2h ST段回落>50%率高于对照组(85.71%vs.52.63%)(P<0.05),抽吸组慢血流或无血流发生率低于对照组(4.76%vs.31.58%)(P<0.05);两组术后4周内主要心脏不良事件差异无统计学意义。结论血栓抽吸是治疗AMI合并血栓者的简单、有效方法,可提高PCI的治疗成功率,能有效改善患者预后。
Objective To evaluate the effectiveness of thrombus aspiration catheters in emergency percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Methods Forty AMI patients who underwent thrombosis after emergency PCI were included in this study. Twenty-one patients were divided into aspiration group and Thrombuster II thrombus aspiration catheter for coronary artery thrombosis, followed by PCI. In the control group, 19 patients were not Suction treatment, according to conventional PCI. The short-term efficacy and safety of the two groups were compared. Results After PCI, the third grade of TIMI in aspiration group was higher than that in control group (95.24% vs.68.42%) (P <0.05) (P <0.05). The incidence of slow or no blood flow in the aspiration group was lower than that in the control group (4.76% vs.31.58%) (P <0.05) ). There was no significant difference in the major cardiac adverse events between the two groups within 4 weeks after operation. Conclusion Thrombus aspiration is a simple and effective method for the treatment of AMI with thrombus, which can improve the success rate of PCI and improve the prognosis of patients.
