背景急性心肌梗死(AMI)是威胁全球公众健康的主要原因之一。虽然已有相应的再灌注治疗策略,但AMI相关的主要不良心脑血管事件(maCCEs)仍然是全世界人口死亡的原因之一。尤其合并糖尿病的AMI患者,因冠状动脉病变复杂,病变程度严重,尽早发现和判断该部分患者远期预后相对困难,因此寻找相对简便、易获得的实验室指标,有利于为2型糖尿病(t.DM)合并AMI患者经皮冠状动脉介入(p.I)术后maCCEs的预测提供依据。目的探讨血清C反应蛋白(CRp./白蛋白(Alb)比值(CAR)对t.DM合并AMI患者p.I术后远期maCCEs的预测价值。方法纳入2014—2019年就诊于宁夏医科大学总医院心血管内科1683例t.DM合并AMI患者为研究对象,收集患者的一般临床资料与检查结果。对所有患者进行电话或门诊随访,以全因死亡、非致死性心肌梗死、再发不稳定型心绞痛、非致死性脑卒中、新发心力衰竭或心力衰竭加重再入院、再次血运重建作为maCCEs。根据患者随访期间是否发生maCCEs分为maCCEs组(508例)和非maCCEs组(1175例)。采用单因素及多因素Logist.c回归分析探讨t.DM合并AMI患者maCCEs事件的影响因素。采用Kap.an-Meier法绘制患者的生存曲线,生存曲线的比较采用Log-rank检验。采用受试者工作特征(ROC)曲线分析CAR对t.DM合并AMI患者远期发生maCCEs的预测效能,使用净重分类改善指标(NRI)和综合判别指数(IDI)评价CAR对t.DM合并AMI患者预后评估的改善效果。结果1683例患者中508例(30.18%)患者发生maCCEs。多因素Logist.c回归分析显示高血压病[OR(95%CI)=1.994(1.142~3.483)]、冠状动脉植入支架长度[OR(95%CI)=1.031(1.002~1.062)]、CRp.OR(95%CI)=0.950(0.915~0.986)]、Alb[OR(95%CI)=0.933(0.880~0.989)]及CAR[OR(95%CI)=5.582(1.705~18.277)]是t.DM合并AMI患者p.I术后发生maCCEs的影响因素(p.0.05)。根据CAR中位表达水平(0.86),将患者分为CARmaCCEs发生率高于CARp.0.001)。ROC曲线显示CAR预测t.DM合并AMI患者发生maCCEs的ROC曲线下面积为0.728(95%CI=0.702~0.754),最佳截断值为0.576,灵敏度为0.617,特异度为0.747。在基线模型基础上,与CRp.Alb相比,CAR能明显改善对患者发生maCCEs的预测效果(NRI=0.377,IDI=0.166,C指数=0.690;p.0.05)。结论CAR是t.DM合并AMI患者p.I术后远期maCCEs发生风险的有效预测指标。
