摘要 目的探讨血清基质金属蛋白酶-2(Matrix Metalloproteinase-2,MMP-2)与急性冠脉综合征(Acute Coro-nary Syndrome,ACS)的关系。方法经冠脉造影(CAG)确诊的冠心病患者70例,其中ACS患者52例(急性心肌梗死19例,不稳定心绞痛33例),稳定型心绞痛18例,另设24例经冠脉造影排除冠心病患者作为正常对照组。运用酶联免疫吸附法(ELISA)测定各血清MMP-2浓度。结果ACS组MMP-2水平(56.88±11.87ng/ml)显著高于SAP组(47.21±10.77ng/ml)及正常对照组(44.56±10.51ng/ml)(均P<0.01),SAP组与正常对照组间MMP-2水平无显著差异;ACS患者中AMI组和UAP组MMP-2水平显著高于正常对照组(均P<0.01);ACS患者中AMI组(61.63±14.81ng/ml)及UAP组(54.35±9.28ng/m1)MMP-2水平也显著高于SAP组(P分别<0.01和<0.05);MMP-2水平与冠脉病变支数、冠脉病变评分及冠脉狭窄程度之间呈显著正相关。结论急性冠脉综合征患者血清MMP-2浓度明显升高,可作为急性冠脉综合征的临床监测指标。
