这项研究发现,患有急性冠状动脉综合征 (ACS) 的患者内皮功能受损,瘤亡因子-α (TNF-α) 和瘤亡因子-α (IL-6) 的水平升高,高TNF-α表明患有重大心血管不良事件的风险更高.
科学领域:
- 心血管医学 心血管医学
- 免疫学 免疫学 免疫学
- 生物标志物 生物标志物
背景情况:
- 内皮功能障碍和炎症是冠状动脉疾病 (CAD) 进展和急性冠状动脉综合征 (ACS) 病理生理学的关键因素.
- 评估内皮功能和炎症标志物可能为ACS患者提供预后见解.
研究的目的:
- 为了研究内皮功能和促炎性细胞因子的预后价值在接受ACS的患者中.
- 为了将内皮功能和炎症的标志物与ACS诊断和主要不良心血管事件 (MACE) 相关联.
主要方法:
- 流介导扩张 (FMD) 评估了内皮功能.
- 瘤亡因子-α (TNF-α) 和IL-6 (IL-6) 水平通过ELISA测量.
- 在ACS患者中对MACE的随访,包括心血管死亡,心肌梗塞,中风和住院治疗.
主要成果:
- 与稳定的CAD相比,在ACS患者中观察到患上口病的恶化和TNF-α和IL-6水平的升高.
- 增加的TNF-α,IL-6水平和受损的口炎与ACS的更高几率相关.
- 在ACS患者中,TNF-α水平>5.19 pg/mL独立预测MACE的风险增加2.5倍.
结论:
- 患有ACS的患者表现出内皮功能受损和IL-6和TNF-α水平升高.
- 在ACS患者中,TNF-α是MACE的显著独立预测因子.
- 内皮功能障碍和特定的炎症标记在ACS预后中至关重要.
