【摘要】 目的观察急性ST段抬高型心肌梗死(STEAMI)患者行急诊经皮冠状动脉介入治疗(PCI)术前、术后白细胞介素-6(IL-6)浓度变化与无复流(NR)的关系,探讨其临床意义。方法将发病12h内接受急诊PCI治疗,术后造影显示TIMI 3级血流的STEAMI患者42例分为无复流组和再灌流组。应用酶联免疫吸附试验(ELISA)检测患者血清IL-6浓度。结果无复流组较再灌注组术后各时间点IL-6水平明显增高(P<0.05),两组术后24h、48h的IL-6浓度与术前比较均有明显增高(P<0.05)。结论 AMI患者急诊PCI术后血清IL-6浓度增高可作为筛选无复流的潜在生化指标。更多还原

【Abstract】 Objective To observe the interleukin(IL-6) levels at different time in the patients with ST segment elevation acute myocardial infarction before and after pecutaneous coronary intervention and to evaluate the clinical significance.Methods To seclect the clinical case and experimental design: 42 patients with ST segment elevation acute myocardial infarction(STEAMI) with successfully treated by PCI within 12h of onset and showed Thrombosis in Myocardial Infarction(TIMI)grade 3 blood flow by coronary arteriongraphy after operation were divided into reperfusion and no-reflow.Enzyme linked immunosorbent assay(ELISA) was used for the detection of IL-6.Results The IL-6 levels at all times of post-operation have significant difference in the non reperfusion group and reperfusion group.Moreover,the IL-6 levels all obviously increased at 24h and 48h after operation in both groups(P<0.05).Conclusion High IL-6 levels in the blood of AMI patient after emergency PCI surgery could be considered as screening index of no reflow(especially at 48h of post-operation).更多还原
