摘要 目的观察急性冠脉综合征(ACS)患者外周血T淋巴细胞亚群、自然杀伤细胞(NK)及超敏C-反应蛋白(HsCRP)的变化,以及与预后的关系。方法选择ACS患者60例,其中不稳定性心绞痛(UA)患者22例,非ST段抬高心肌梗死(NSTEMI)患者19例,ST段抬高心肌梗死(STEMI)患者19例;并选42例稳定性心绞痛(SAP)患者为对照组。采用流式细胞仪测定所有病例外周血CD3+T细胞、CD4+T细胞、CD8+T细胞、NK细胞亚群占总T淋巴细胞比例,同时计算CD4+/CD8+值,并测定HsCRP浓度;同时所有ACS患者随访1年,观察其再梗死、严重心力衰竭、恶性心律失常及猝死的发生情况。结果 ACS组患者外周血CD4+T细胞、CD4+/CD8+值、NK细胞比例均较对照组低(均<0.05);而CD8+T细胞比例、HsCRP浓度高(<0.05),并随着ACS症状越重,变化更明显,CD4+/CD8+值降低者发生严重心血管事件的比例较高。结论 ACS患者存在有免疫功能异常,主要是细胞免疫功能受到抑制,并与疾病的严重程度具有一定的相关性,CD4+/CD8+值降低的ACS患者预后不良。
