摘　　要：目的观察接受急诊经皮冠状动脉介入治疗（PCI）的急性ST段抬高型心肌梗死（STEAMI）患者,不同长度支架对患者无复流/慢血流发生的影响。方法回顾性分析2013年5月-2015年11月于全国军队医院急诊诊断为STEAMI并行急诊PCI的患者2 919例,按植入支架总长度（L）分成3组,观察患者术中无复流/慢血流现象的发生及住院期间主要不良心血管事件（MACE）的发生情况。结果 STEAMI患者急诊PCI后无复流/慢血流的发生率为16.4%,其中A组发生率为13.4%,B组发生率为15.4%,C组发生率为21.7%,3组比较差异有统计学意义（P〈0.05）。所有患者住院期间MACE总的发生率为6.4%,A、B、C 3组的MACE发生率分别为6.2%、6.1%、7.0%,差异无统计学意义（P〉0.05）。结论 STEAMI患者急诊PCI后,无复流/慢血流的发生率可能与支架总长度有关。Objective To study the impact of stent length on no-reflow or slow flow phenomenon in the patients with acute ST-segment elevation myocardial infarction（STEAMI） after primary percutaneous coronary interventional（PCI）, through observation of2919 clinical cases. Methods The data of patients diagnosed with STEAMI who underwent PCI performed in the national military hospitals from May 2013 to November 2015 were analyzed retrospectively and divided into three groups according to total stent length（L）, Patients＇ no-reflow or slow flow phenomenon during PCI treatment and major adverse cardiovascular events（MACE） during the hospitalization were observed. Results The total incidence of no-reflow or slow flow phenomenon in patients with primary PCI after STEAMI was 16.4%; incidence for groups A, B and C were 13.4%, 15.4% and 21.7% respectively, with significant difference（P〈0.05）. Among all hospitalized patients,6.4% had MACE,with rates for A,B and C groups at 6.2%,6.1%,and 7.0% respectively; the differences were statistically significant（P〉0.05）. Conclusion There might be some connections between the no-reflow or slow flow phenomenon and total stent length in patients with STEAMI after primary PCI.
