目的:评估血栓抽吸装置在急性心肌梗塞(AMI)急诊冠状动脉介入治疗(PCI)患者治疗中的临床应用。方法:86例行急诊PCI治疗的AMI患者被随机分为血栓抽吸组(41例,应用抽吸导管后再行PCI),直接PCI组(45例,直接行PCI),观察无复流发生率、术后ST段下降率及左心室射血分数等。结果:PCI后血栓抽吸组患者的无复流发生率明显低于直接PCI组(4.9%∶11.1%,P<0.05),ST段回落率(66.67%、75.61%)、LVEF[(54.02±8.93)%∶(49.23±9.12)%]均优于直接PCI组(P均<0.05)。结论:急诊冠脉介入治疗急性心肌梗塞患者时,应用血栓抽吸导管可以降低无复流发生率,改善心功能,且安全有效。
Objective: To evaluate the clinical application of thrombus aspiration in the treatment of patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI). Methods: Eighty-six AMI patients undergoing emergency PCI were randomly divided into thrombus aspiration group (41 cases, PCI with suction catheter) and direct PCI group (45 cases with direct PCI) to observe the occurrence of no-reflow Rate, postoperative ST segment decline rate and left ventricular ejection fraction. Results: The incidence of no-reflow was significantly lower in patients with thrombus aspiration after PCI than those in the direct PCI group (4.9% vs 11.1%, P <0.05), ST-segment regression rates (66.67%, 75.61% 8.93)% (49.23 ± 9.12)%] were better than the direct PCI group (all P <0.05). Conclusions: When emergency PCI is used to treat patients with acute myocardial infarction, the use of thrombus aspiration catheter can reduce the incidence of no-reflow, improve cardiac function and be safe and effective.
