摘要 目的研究脑梗死患者血清基质金属蛋白酶-9(MMP-9)水平及颈动脉粥样硬化斑块,探讨颈动脉粥样硬化斑块稳定性与MMP-9水平的关系。方法对82例颈内动脉系统的急性脑梗死患者(CI组)及20例短暂性脑缺血发作患者(TIA组)通过彩色多普勒超声检查颈动脉粥样硬化斑块,同时检测患者血清MMP-9水平,并与健康对照组(40名)比较。根据斑块性质将CI组分为不稳定斑块组、稳定斑块组及无斑块组三个亚组,再进行组内比较。结果 CI组、TIA组斑块检出率、不稳定斑块率及血清MMP-9水平均明显高于对照组(P<0.05);脑梗死不稳定斑块组MMP-9水平又显著高于稳定斑块组,稳定斑块组较无斑块者明显增高(P<0.05)。结论颈动脉粥样硬化斑块及其稳定性与脑梗死发生有密切关系,MMP-9可能是不稳定性粥样硬化斑块及脑梗死的一个潜在的血清标志物。
