摘　　要：目的：采用 Logistic回归和受试者特征曲线（ROC）方法评价缺血修饰清蛋白（IMA）、中性粒细胞淋巴细胞比率（NLR）、超敏C反应蛋白（hs-CRP）以及肌酸激酶同工酶（CK-MB）单项及联合检测对急性心肌梗死（AMI）的早期诊断价值。方法检测胸痛发生后3 h内和3～6 h内95例 AMI患者血清 IMA，hs-CRP，CK-MB和 cTnI以及全血 NLR水平，并与60例来自体检中心的人群（作为阴性对照）做比较。应用 Logistic回归模型，绘制 ROC曲线，计算曲线下面积（AUC）评价各指标的诊断价值。结果①胸痛0～3 h AMI组 IMA，NLR，hs-CRP，CK-MB和 cTnI的平均值分别为96.04U／L，3.77，13.39mg／L，43.26U／L和0.063 ng／ml，均高于对照组的78.10 U／L，2.02，3.12 mg／L，19.37 U／L和0.040 ng／ml，差异有统计学意义（P均＜0.01）。胸痛3～6 h AMI组 IMA，NLR，hs-CRP，CK-MB和 cTnI指标均高于0～3 h AMI组，差异有统计学意义（P均＜0.05）。②胸痛0～3 h AMI组 IMA，NLR，hs-CRP和 CK-MB 4项联合诊断早期 AMI的 ROC AUC为0.98，高于各指标单项检测的 AUC（分别为0.89，0.83，0.79和0.85）。同时，4项联合检测对早期 AMI诊断价值也显著高于心梗诊断的经典血清学指标 cTnI（AUC＝0.78）。结论 IMA，NLR，hs-CRP和 CK-MB联合检测有助于提高早期 AMI的诊断效能，优于各单项目检测。Objective To assess the diagnostic value of IMA,NLR,hs-CRP and CK-MB individually and the combined detec-tion for early acute myocardial infarction using ROC curve and Logistic regression.Methods To detect levels of IMA,NLR, hs-CRP,CK-MB and cTnI in serum or whole blood of AMI patients that had chest pain within 3 hours or between 3 and 6 hours,compared with 60 healthy people from Physical Examination Center.Applied Logistic regression,plotted ROC curve and calculated the area under ROC curve （AUC）to assess the diagnostic value of each index.Results The serum IMA,hs-CRP,CK-MB and cTnI or whole blood NLR levels of AMI patients with 3 hours were remarkably higher than normal con-trol,showing significant statistical difference （P〈0.01）（AMI group：mean values of IMA,NLR,hs-CRP,CK-MB and cTnI were 96.04 U/L,3.77,13.39 mg/L,43.26 U/L and 0.063 ng/ml;normal control group：mean values of IMA,NLR,hs-CRP,CK-MB and cTnI were 78.10 U/L,2.02,3.12 mg/L,19.37 U/L and 0.040 ng/ml.The serum IMA,NLR,hs-CRP, CK-MB and cTnI levels of AMI patients in the group between 3~6 hours were higher than in the group within 3 hours （P〈0.05）.The AUC of combined detection of IMA,NLR,hs-CRP and CK-MB for early AMI was 0.98,higher than solo de-tection of IMA,NLR,hs-CRP and CK-MB,which were 0.89,0.83,0.79 and 0.85 respectively.Meanwhile,the AUC of com-bined detection for four markers also surpassed that of cTnI alone that was recognized as a classic serological marker to diag-nose AMI （AUC=0.78）.Conclusion The combined detection of IMA,NLR,hs-CRP and CK-MB is superior to a single in-dex detection,which can significantly improve diagnostic efficiency for early AMI.
