摘要 目的观察非瓣膜性房颤患者血清微小RNA-29b(miR-29b)与基质金属蛋白酶9(MMP-9)水平,并探讨其意义。方法入选非瓣膜性房颤患者51例(观察组)、窦性心律患者31(对照组),所有患者入院后采用心脏彩超检查测左房内径(LAD);均于第2天清晨取空腹静脉血5 m L,采用实时荧光定量PCR法检测血清miR-29b,采用酶联免疫法检测血清MMP-9。结果对照相与观察组比,LAD显著增大(P<0.01),miR-29b显著降低(Z=-7.45,P<0.01),MMP-9明显升高(Z=-7.52,P<0.01)。Spearman秩相关分析显示,非瓣膜性房颤患者血清miR-29b与LAD呈负相关关系(r=-0.40,P<0.01);血清MMP-9与LAD呈正相关关系(r=0.41,P<0.01);血清miR-29b与MMP-9呈负相关关系(r=-0.89,P<0.01)。结论非瓣膜性房颤患者血清miR-29b水平降低,MMP-9水平升高,二者成负相关关系,可能在心房结构重构中发挥作用。
