摘要
目的研究急性脑梗死不同性质颈动脉斑块与基质金属蛋白酶-9(matrix metalloproteinase-9,MMP-9)之间的关系,探讨颈动脉粥样硬化斑块稳定性及MMP-9水平在脑梗死发生中的作用及临床意义。方法113例急性脑梗死患者组(ACI)和31例健康对照组,根据颈动脉彩超将脑梗死组分为无斑块组(NP)(39例)、稳定斑块组(SP)(34例)、不稳定斑块组(VP)(40例)3个亚组。测定对照组及急性脑梗死患者发病48 h内和d 14血清MMP-9水平,并进行相关分析。结果急性脑梗死患者入院48 h内和d 14血清MMP-9水平4组比较差异均有统计学意义(P<0.05),血清MMP-9与梗死体积(r=0.289,P=0.002)、空腹血糖(r=0.200,P=0.034)及血压(P<0.05)呈正相关。结论MMP-9参与了动脉粥样硬化的形成及斑块的不稳定性,可能是急性脑梗死的血清标志物。
