摘要 目的观察基质金属蛋白酶-9(MMP-9)在急性冠脉综合征(ACS)患者外周血中的水平及其与血小板胞浆内α-颗粒上的膜糖蛋白(CD62p)、溶酶体膜糖蛋白(CD63)的相关性,探讨MMP-9在ACS发生发展中的作用。方法选取ACS患者50例和正常对照组40例,采用夹心酶联免疫吸附测定法测定外周血MMP-9,采用全血流式细胞术测定CD62p和CD63。结果ACS组患者血浆MMP-9、CD62p、CD63水平均显著高于对照组(P均<0.01)。MMP-9与CD62p、CD63水平呈正相关(相关系数分别为r=0.402和r=0.427,P均<0.01)。结论MMP-9水平增高是ACS发生的危险因素之一,在粥样斑块的发生、发展中起着重要的作用。
