摘要
目的:探讨血清中基质金属蛋白酶-2(Matrix Metalloproteinases-2,MMP-2)及其抑制因子(Tissue inhibitor of metallop roteinase 2,TIMP-2)与心房颤动(房颤)患者心功能、左房内径的关系。方法:选择49例持续性(持续时间大于7d)房颤患者和47例窦性心律患者,分为房颤组和窦律组。采用ELISA测定两组血清MMP-2、TIMP-2水平,并用彩超测量两组患者左房内径的大小。结果:(1)房颤组血清MMP-2水平明显高于窦律组(P<0.05),且与左房内径大小呈直线正相关关系(r=0.345,P<0.05)。TIMP-2水平在房颤组与窦律组间无差异(P>0.05)。(2)房颤组患者左房内径水平明显高于窦律组(P<0.01)。结论:房颤组患者的MMP-2水平较窦律组高,且随心功能恶化而升高,可能是导致持续性房颤患者左心房内径扩大的原因之一。
