摘要 目的探讨血浆或血清微小RNA(miR)-1及miR-21在房颤患者中的表达及二者的联合检测价值。方法收集房颤(AF)患者60例及健康对照30例,使用实时荧光定量PCR技术检测miR-1及miR-21表达并分析与临床指标间的相关性,使用受试者工作特征(ROC)曲线评估miRNA作为血清学指标区分疾病的能力。结果血清miR-1的相对表达水平在对照组、阵发性AF及持续性AF组中呈递减趋势,差异具有显著性。与对照组相比,阵发性AF及持续性AF组血清miR-21的相对表达水平显著降低。miR-1与miR-21表达呈正相关,与左室收缩末期内径(LVDs)、左房内径(LAD)呈负相关;miR-21的表达与LAD亦呈负相关。ROC曲线分析显示miR-1、miR-21及联合检测因子miR-1×miR-21在区分AF方面均有良好的敏感性和特异性。结论血清miR-1和miR-21在AF患者中表达下调,提示二者或可成为检测AF的潜在血清学指标。
