目的探讨血尿素氮(BUN)水平与急性冠状动脉综合征(ACS)患者接受经皮冠状动脉介入(PCI)治疗后发生主要心血管不良事件(MACE)的关联及预测价值。方法选取2017年4月至2017年11月在首都医科大学附属北京安贞医院心内科首次接受PCI手术的ACS患者。经过36个月的随访,本研究共纳入了487例患者,包括114例发生MACE的受试者和373例没有发生MACE的受试者。利用Cox比例风险回归模型分析BUN与ACS患者PCI术后发生MACE的风险比及其95%CI,并使用受试者工作特征(ROC)曲线下面积(AUC)变化来评估BUN的预测效果。结果调整混杂因素后,Cox比例风险回归分析显示,与低水平BUN组相比,高水平BUN组发生MACE风险增加约4倍(OR=4.722,95%CI 1.716~12.993)。将BUN纳入心血管事件风险的基本预测模型及SCORE模型后,AUC面积显著提高(P<0.001)。结论血BUN可独立于传统危险因素预测ACS患者PCI术后的MACE风险。
