摘要 目的探讨进展性脑梗死(PCI)患者血清基质金属蛋白酶(MMP)-9的动态变化及与病情严重程度和梗死体积相关性。方法观察283例脑梗死患者,76例PCI,207例非进展性脑梗死(NPCI)和36名健康对照组血清MMP-9水平及脑梗死患者的梗死体积和各时段的美国国立卫生研究院卒中量表(NHISS)评分。结果 PCI患者血清MMP-9水平在入院24 h内、第3天、第5天、第7天明显高于NPCI组及正常对照组(均P<0.01);PCI患者血清MMP-9水平与梗死体积(r=0.655)及病情严重程度(r=0.827)相关(均P<0.05);发病后第3天的血清MMP-9水平为PCI的独立危险因素(OR=1.013,P<0.05)。结论发病后第3天的血清MMP-9水平、患者发病1 w时的梗死体积和发病后病情最严重时的NIHSS评分相关。急性期脑梗死血清MMP-9水平是PCI的独立危险因素之一,可作为急性期PCI的早期实验室预测指标。
