摘要: 目的 探讨白细胞计数与急性ST段抬高型心肌梗死(ST-segment elevation myocardial infarction,STEMI)病人直接经皮冠状动脉介入术(percutaneous coronary intervention,PCI)中无复流的关系。方法 选取2013年11月至2015年12月因急性STEMI住院并行直接PCI的病人266例,根据PCI术中无复流发生情况分为正常复流组(A组)242例和无复流组(B组)24例。比较两组病人临床资料特点及住院期间主要不良心血管事件(major adverse cardiovascular events,MACE)发生率,采用Logistic回归分析筛选急性STEMI病人PCI术中无复流的影响因素。结果 无复流组白细胞计数、血肌酐明显高于正常复流组(P<0.05),Killip ≥ 3级比例显著升高(P=0.009);两组病人住院期间MACE发生率分别为16.7%和2.9%(P=0.001)。多因素Logistic回归分析结果显示白细胞计数(OR=1.220,95%CI:1.064~1.399,P=0.004)、Killip分级(OR=4.617,95%CI:1.093~2.095,P=0.037)是急性STEMI病人PCI术中无复流的独立预测因素。结论 入院时白细胞计数是急性STEMI病人PCI术中无复流的独立预测因素,早期检测白细胞计数可以初步评估PCI术中无复流的发生风险。

Abstract: Objective To investigate the relationship between leukocyte count and Intra-operative no-reflow of acute ST-segment elevation myocardial infarction (STEMI) patients with percutaneous coronary intervention (PCI). Methods Two hundred and sixty-six acute STEMI patients were categorized into group A (without intra-operative no-reflow, n=242) and group B (with intra-operative no-reflow, n=24) according to the intra-operative no-reflow.Clinical data were compared between the two groups, including age,gender,hypertensive history,diabetes mellitus history,smoking status,blood pressure,heart rate,white blood cell count (WBC), low density lipoprotein-cholesterol (LDL-C), fasting plasma glucose (FPG), Killip class,the lesion count, and the incidence of in-hospital major adverse cardiovascular events (MACE) was also compared. Multivariate logistic regression analysis was used to analyze the influencing factors of intra-operative no-reflow of acute STEMI patients treated with primary PCI. Results The leukocyte count, serum creatinine,the incidence of Killip class ≥ three and in-hospital MACE in group B was significantly higher than that in group A. Multivariate Logistic regression analysis showed that,leukocyte count(OR 1.220,95%CI 1.064-1.399,P=0.004), Killip class(OR 4.617,95%CI 1.093-2.095,P=0.037)were independent risk factors of intra-operative no-reflow of acute STEMI patients treated by primary PCI. Conclusion leukocyte count was an independent risk factor of intra-operative no-reflow of acute STEMI patients treated by primary PCI.
