摘要(Abstract)：

目的探讨冠状动脉介入治疗(PCI)后纤维蛋白原(fibrinogen,FIB)和超敏C反应蛋白(high-sensitivity C-reactive protein,hs-CRP)联合应用预测急性ST段抬高型心肌梗死(ST elevated myocardial infarction,STEMI)患者近、远期预后的价值。方法183例发病12h内接受成功PCI治疗的初发急性STEMI患者被入选。PCI术后12h内进行FIB和hs-CRP检测。对患者进行长期随访,一级终点为全因死亡,二级终点为心脏事件联合终点,包括非致死性心肌梗死、心力衰竭(NYHA Ⅲ～Ⅳ)、心肌缺血(负荷试验证实)、再次血管重建及死亡。结果PCI术后FIB和hs-CRP呈线性相关(r=0.452,P<0.0001),ROC曲线确定诊断界值分别为510mg/L(灵敏度69.2%,特异度81.6%)和14mg/L(灵敏度84.6%,特异度73.1%)。将患者分为3组:第1组,FIB<510mg/L+hs-CRP<14mg/L;第2组,FIB<510mg/L+hs-CRP≥14mg/L或FIB≥510mg/L+hs-CRP<14mg/L;第3组,FIB≥510mg/L+hs-CRP≥14mg/L。三组相比近期和远期死亡(30天:χ2=11.74,P=0.003;2年:χ2=27.04,P<0.0001)及心脏事件发生率(30天:χ2=14.34,P=0.001;2年:χ2=13.55,P=0.001)明显不同;30天累积生存率(97.9%比98.0%比83.9%,P=0.002)和2年累积生存率(97.8%比95.8%比69.0%,P<0.0001)差异有统计学意义,其中第3组患者近、远期死亡及心脏事件发生率最高,累积生存率最低。多因素COX回归分析显示,PCI术后FIB≥510mg/L且hs-CRP≥14mg/L的患者与FIB<510mg/L或hs-CRP<14mg/L的患者相比,30天(HR7.95,P=0.018)和2年内(HR12.59,P=0.002)发生死亡的风险分别增加7.95倍和12.59倍。结论急性STEMI患者成功PCI治疗后FIB≥510mg/L且hs-CRP≥14mg/L的患者近期和远期预后不良。
