摘要：日的探讨不稳定性心绞痛(UAP)患者白细胞介素一6(IL一6)及高敏C反应蛋白(hs—CRP)的变化及其临床意 义。方法 连续选择uAP患者64例(UAP组)，同期检查的稳定性心绞痛患者66倒(SAP组)，分析两组患者冠 心病危险因素及血浆11．-6和hs—CRP水平。结罩 UAP组患者的空腹血糖、收缩压、TC、LDL—C、吸烟指数、血浆 II．一6和hs—CRP浓度均明显高于sAP组。logistic逐步回归分析显示，血浆1L一6和hs—CRP浓度与UAP呈显著正 相关。直线相关分析，UAP患者的血浆IL一6、hs—CRP水平与冠状动脉狭窄程度和Gensini积分呈显著正相关，同 时UAP患者血浆IL一6和hs—CRP水平之间也具有直线相关性。结论 炎性因子IL一6与hs—CRP是UAP发病的 独立危险因素。 关键词：心绞痛，不稳定型；白细胞介素6；C反应蛋白质；冠状动脉疾病；危险因素 中图分类号：R541．4 文献标识码：A 文章编号：1009—0126(2008)06—0434—03

不稳 定性心绞痛(UAP)是介于稳定性心绞痛(SAP)和 急性心肌梗死间的一种心肌缺血症候群。我们分析 了UAP患者各种危险因素，并与SAP患者比较， 现报道如下。
