摘要 目的:探讨冠心病患者B型脑钠肽和基质金属蛋白酶-9的关系。方法:选取2017年1月~2018年12月在我院心内科住院,并行冠状动脉造影检测的患者共118例为研究对象。根据造影结果分为非冠心病组35例(对照组)和冠心病组83例,其中单支病变25例,双支病变28例,三支病变23例,左主干病变7例。冠心病患者根据临床表现并结合实验室检查及心电图等分为稳定型心绞痛组41例(SAP)和急性心肌梗死组42例(AMI)。比较患者血清中B型脑钠肽(BNP)水平和基质金属蛋白酶(MMP-9)水平,并分析MMP-9水平与BNP水平的关系。结果:三组患者BNP、MMP-9水平和Gensini积分间差异均有统计学意义(P<0.05)。AMI组的BNP、MMP-9水平和Gensini评分明显高于SAP组和对照组,而SAP组的BNP、MMP-9水平和Gensini评分明显高于对照组;左主干病变患者的BNP和MMP-9水平最高,其次分别为三支病变、双支病变和单支病变,差异均有统计学意义(P<0.001);通过Pearson相关系数分析,冠心病患者的BNP水平和MMP-9水平呈正相关(r=0.758,P<0.001);MMP-9水平与Gensini呈正相关(r=0.642,P<0.001);BNP水平与Gensini亦呈正相关(r=0.584,P<0.001)。结论:BNP水平与MMP-9水平有较好的相关性,且其与Gensini积分均有较好的相关性,推测在临床上测定BNP水平和MMP-9水平有助于诊断冠心病及其病变程度,对其治疗和预后有一定的指导意义。
