摘要
目的分析血栓抽吸对急性ST段抬高型心肌梗死患者急诊经皮冠状动脉介入(PCI)术后临床预后的影响。方法随机选择2009年9月至2012年1月于我院确诊为急性ST段抬高型心肌梗死并行急诊PCI治疗的患者239例,其中血栓抽吸+PCI118例(血栓抽吸组),直接PCI组121例,对两组患者的造影及临床结果进行回顾性分析。结果血栓抽吸组在即刻血流TIMI3级[106(89.8%)与96(79.3%);χ2=5.026,P〈0.05]、PCI术后2h心电图ST段回落率≥50%[101(85.6%)与90(75.2%);χ2=5.500,P〈0.05]、术后1周内射血分数≥50%[68(57.6%)与52(43.0%);χ2=5.130,P〈0.05]、住院期间再梗死发生率[0(0)与5(4.1%);χ2=4.980,P〈0.05]都明显优于直接PCI组,差异均有统计学意义;在平均住院时间[(10.05±5.40)d与(10.40±5.03)d;t=-0.525,P〉0.05]、术中心室颤动发生率[4(3.4%)与3(2.5%),χ2=0.174,P〉0.05]、住院期间发生心力衰竭[15(12.7%)与18(14.9%);χ2=0.235,P〉0.05]、恶性心律失常[12(10.2%)与15(12.4%);χ2=0.296,P〉0.05]及病死率[2(1.7%)与5(4.1%);χ2=1.248,P〉0.05]等方面差异均无统计学意义。结论急性sT段抬高型心肌梗死患者行急诊PCI时应用血栓抽吸可能改善临床预后,是一种安全、有效的方法。
Objective To evaluate the effects of thrombus aspiration on postoperative clinical prognosis of acute ST-segment elevation myocardial infarction (STEMI) patients with emergency percutaneous coronary intervention(PCI). Methods From September 2009 to January 2012, a total of 239 patients with STEMI undergoing emergency PCI ( thrombus aspiration + PCI ( n = 118 ) and PCI ( n = 121 ) ) were enrolled in this study. The angiographic and clinical results were retrospectively analyzed and compared between the two groups of patients. Results There were significant differences between the thrombus aspiration group and the PCI group on instant blood flow TIMI3 grade ( 106 ( 89. 8% ) vs. 96 ( 79. 3% ) ; X2 = 5. 026, P 〈 0. 05 ), ST-segment depression rate at two hours after surgery ( 101 ( 85.6% ) vs. 90 ( 75.2% ) ; χ2 = 5. 500, P 〈 0.05 ), ejection fraction within one week after surgery ( 68 ( 57.6% ) vs. 52 ( 43.0% ) ; χ2 = 5. 130, P 〈 0. 05 ), incidence of reinfarction during hospitalization ( 0 ( 0 ) vs. 5 ( 4. 1% ) ; χ2 = 4. 980, P 〈 0. 05 ). There were no significant statistical difference between the two groups on the average length of stay ( ( 10. 05 ± 5.40) d vs. ( 10. 40 ± 5.03 ) d; t = - 0. 525, P 〉 0. 05 ), incidence of ventricular fibrillation during surgery ( 4 ( 3.4% ) vs. 3 ( 2. 5 % ; X2 =0. 174 ,P 〉 0. 05 ), heart failure during hospitalization ( 15 ( 12. 7% ) vs. 18 ( 14. 9% ) ; χ2 = 0. 235, P 〉 0. 05) ,Malignant arrhythmias ( 12 ( 10. 2% ) vs. 15 ( 12.4% ) ; χ2 = 0. 296, P 〉 0. 05 ), and mortality rate (2 (1.7%) vs. 5(4. 1% ) ;χ2 = 1. 248,P 〉0. 05). Conclusion Application of thrombus aspiration,which is a safe and effective way, may improve the clinical outcomes in acute ST-segment elevation myocardial infarction patients with emergency PCI.
