高灵敏度C反应蛋白 (hs-CRP) 表明,在接受双抗血小板治疗 (DAPT) 的急性冠状动脉综合征 (ACS) 患者中,出血的风险更高. 升高的hs-CRP水平与增加住院重大出血事件有关.
科学领域:
- 心脏病学 心脏病学
- 生物标志物 生物标志物
- 临床研究 临床研究
背景情况:
- 急性冠状动脉综合征 (ACS) 管理通常涉及皮肤冠状动脉干预后的双重抗血小板治疗 (DAPT).
- 在接受DAPT的ACS患者中,出血是显著的并发症.
- 识别出出血风险的预测因素对于优化患者护理至关重要.
研究的目的:
- 为了研究高灵敏度C-反应蛋白 (hs-CRP) 与DAPT.治疗的ACS患者的出血事件之间的关联.
- 确定hs-CRP是否是该人群中主要出血的独立预测因素.
主要方法:
- 一项观察性多中心研究包括2583名非ST段升高ACS (NSTE-ACS) 的成年患者.
- 通过皮肤冠状动脉干预后,患者接受了DAPT.
- 主要出血 (出血学术研究联盟3-5年级) 是主要结果,死亡和任何出血是次要结果.
主要成果:
- 53名 (2.1%) 患者出现严重出血.
- 较高的hs-CRP水平 (>8.20 mg/L) 与显著更高的住院大出血发病率 (3.9%,p<0.001) 相关.
- 多变量分析证实hs-CRP是入院大出血的独立预测因子 (调整后OR=1.01每毫克/升增加,p<0.001).
- 在hs-CRP水平和重大出血风险之间观察到一个S型的关联.
结论:
- 通过hs-CRP表示的全身炎症与DAPT的NSTE-ACS患者在医院内大出血的风险增加有关.
- hs-CRP与出血事件之间的关系遵循一个S形曲线.
- 需要进一步的研究,以优化高出血风险患者的抗血栓治疗.
