摘要 目的探讨单核细胞趋化蛋白(MCP)-1在老年急性冠脉综合征(ACS)患者血浆中的表达及意义。方法选取2014年1月至2015年5月玉林市第一人民医院心内科收治的老年ACS患者75例和同期健康查体者22例作为研究对象。75例老年ACS患者中稳定型心绞痛(SAP组)者26例,不稳定型心绞痛(UAP组)24例和急性心肌梗死(AMI组)25例。上述研究对象采用酶联免疫吸附试验(ELISA)检测血清MCP-1和心肌肌钙蛋白(c Tn)I水平。比较MCP-1在上述患者中有无差别、血清MCP-1与c Tn I的相关性及血清MCP-1诊断ACS的价值。结果对照组MCP-1为(98.6±10.3)pg/ml,SAP组为(110.6±11.5)pg/ml,UAP组为(149.8±12.7)pg/ml,AMI组为(162.3±13.4)pg/ml。ACS组MCP-1水平显著高于对照组(P<0.05);AMI组显著高于SAP和UAP组(P<0.05);ACS组血浆MCP-1与c Tn I之间存在正相关(r=0.67,P<0.05);以血清MCP-1参考,根据贝叶斯定理绘制受试者工作特征(ROC)曲线,并确定最佳截断值为111.23 pg/ml,该截断值下的诊断敏感性为78.2%,特异性为73.6%,诊断的ROC曲线下面积(AUC)为0.83(P<0.05)。结论老年ACS患者血清MCP-1显著升高,可作为诊断ACS的血清学标志物,且血清MCP-1与病情严重程度存在相关性。
