摘要:

目的 研究急性ST段抬高型心肌梗死(ST-segment elevation myocardial infarction, STEMI)自发再灌注的临床预测指标及其价值.方法 入选2009年1月1日至2010年9月30日260例行急诊冠状动脉造影(coronary angiography, CAG)的初发STEMI患者.所有患者按照溶栓试验血流分级(thrombolysis in myocardial infarction, TIMI)分为自发再灌注(spontaneous reperfusion, SR)组(TIMI 3级)和无自发再灌注(nonspontaneous reperfusion,NSR)组(TIMI 0~2级).比较2组的各项指标,使用Logistic多因素回归分析评价SR的影响因素.结果 2组患者术前ST段回落>50%、术前胸痛缓解>5、血红蛋白、肌酐、尿酸、超敏C反应蛋白和肌酸激酶同工酶比较,差异有统计学意义;Logistic多因素回归分析显示:血红蛋白(OR=1.064,95%CI: 1.036~1.094,P=0.000)、超敏C反应蛋白(OR=0.811,95%CI:0.713~0.923,P=0.001)和术前ST段回落 >50%(OR=3.638,95%CI:1.793~7.318,P=0.000)是自发再灌注的影响因素;3者联合对自发再灌注诊断的敏感度为80.6%,特异度为63.7%,受试者工作特征曲线(receiver operating characteristic,ROC)分析示曲线下面积(area under curve,AUC)为0.78,其95%CI为0.72~0.85.结论 血红蛋白、超敏C反应蛋白和术前ST段回落>50%对于SR可能有一定的预测价值.

Abstract:

Objective To explore the clinical implications of different evaluation methods and value for the prediction of spontaneous reperfusion in ST-segment elevation myocardial infarction (STEMI). Methods A total of 260 patients who underwent coronary angiography (CAG) were enrolled. The patients were divided into spontaneous reperfusion (SR, TIMI flow grade 3 identified by CAG) group (n=67) and nonspontaneous reperfusion (NSR, TIMI flow grade 0-2 identified by CAG) group (n=193). We analyzed the predictive value of ST-segment resolution (STR), hemoglobin (Hb), and high-sensitivity C-reactive protein (hsCRP) in SR in acute myocardial infarction (AMI). Results There was significant difference in ST-segment resolution, symptoms release, Hb, creatinine, uric acid, MB isoenzyme of creatine kinases, and hsCRP between two groups. In Logistic regression model, Hb (OR=1.064,95%CI:1.036-1.094,P=0.000), hsCRP (OR=0.811,95%CI:0.713-0.923,P=0.001) and STR>50% (OR=3.638,95%CI:1.793-7.318,P=0.000) were independent predictors for SR. The receiver-operating characteristic curve (ROC) analysis for Hb, hsCRP, and STR combined in predicting spontaneous reperfusion showed sensitivity of 80.6%, specificity of 63.7%, and area under the curve (AUC)=0.78(0.72-0.85). Conclusion Hb, hsCRP and STR have predictive value for SR.
