摘要：

目的 :探讨白细胞介素 6 (IL 6 )、C 反应蛋白 (CRP)、纤维蛋白原 (Fg)及肺炎衣原体 (Cpn)感染与冠心病 (CHD)间的关系。方法 :急性心肌梗死 (AMI)组、经冠状动脉造影证实的心绞痛 (AP)组及正常对照各 30例。应用放射免疫法检测血清IL 6浓度 ,散射免疫浊度法检测血浆Fg及血清CRP水平 ,并用微量免疫荧光法检测血清Cpn特异性抗体IgG、IgM滴度并检测呼吸道合胞病毒特异性抗体IgG滴度做对照。结果 :AMI组和AP组的血清IL 6、CRP及血浆Fg水平显著高于对照组 (均P<0 .0 1)。血清IL 6、CRP及血浆Fg水平彼此显著相关 (r值分别为 0 .81、0 .80和 0 .6 8,均P <0 .0 1) ,三者水平与AP患者的冠状动脉狭窄危险分数相关。AMI组、AP组血清抗CpnIgG抗体阳性率显著高于对照组 (分别 P <0 .0 1、<0 .0 5 )。三组的Cpn特异性IgM抗体与抗呼吸道合胞病毒IgG抗体阳性率比较差异无显著性意义。抗CpnIgG抗体阳性者IL 6、CRP水平显著高于阴性者。Cpn感染者特异性抗体IgG滴度与血中IL 6、CRP及Fg水平均明显相关。结论 :炎性细胞因子及其诱生的急性相蛋白与CHD发生发展密切相关 ,炎症反应强度可能反映CHD病变程度。Cpn慢性感染与CHD相关 ,并可能通过介导炎症反应参与CHD发生发展
