14、lism.Keywords acute coronary syndrome;CPn-IgG;hs-CRP急性冠脉综合征(acute coronary syndrome,ACS)是一组以冠状动脉粥样硬化斑块破裂、侵袭,从而继发完全或不完全闭塞血栓形成为病理表现的临床综合征,包括急性心肌梗死(acute myocardial infarction,AMI)和不稳定型心绞痛(unstable angina pectoris,UA)1,动脉粥样硬化是一种全身性的免疫炎症性疾病2,其发生发展始终离不开炎症参与,而感染又是炎症的重要诱因。众多病原体中肺炎衣原体(chlamydia pneu-moniae,
15、CPn)作为一种特殊病原微生物,其感染与冠状动脉粥样硬化之间的相关性被越来越多的研究证实3-5。而超敏 C 反应蛋白(hs-CRP)、白细胞计数、纤维蛋白原(Fbg)、白细胞介素-6(IL-6)和肿瘤坏死因子-(TNF-)是炎症反应过程中不可或缺的炎症指标,参与、介导许多炎症反应,同时可以与内皮细胞损伤相互作用,加剧炎症反应,促使 ACS 发生6-9。然而关于 ACS 与 CPn 感染之间的关系近些年鲜有报道。本研究采用酶联免疫吸附法(ELISA)检测 ACS 患者血清 CPn-IgG 水平,探讨 ACS 与 CPn-IgG 的关系。1资料与方法1.1研究对象选取 2017 年 8 月至 20
