目的:探讨ST段抬高性心肌梗死(STEMI)患者的血浆基质金属蛋白酶-9(MMP-9)动态演变的临床意义。方法选择2011年9月-2012年2月的STEMI患者55例,分别在患者症状发作后4 h内及4~8、8~12、12~24、24~48、48~72 h不同时间段采集外周静脉血,用酶联免疫吸附试验(ELISA )检测各时段的血浆MMP-9水平,并与健康志愿者(健康组)50例作比较。采用GRACE评分对STEMI患者的病情进行评估,分析患者MMP-9水平与GRACE的关系。结果 STEMI患者在各时间段的MMP-9水平均高于健康组(P <0.001),4 h内组M M P-9的表达水平低于12~24 h组和48~72 h组( P <0.05),4~8 h组M M P-9的表达水平低于12~24 h组、24~48 h组和48~72 h组(P<0.05)。患者入院时MMP-9水平与GRACE评分呈正相关(r=0.644,P<0.001)。结论 MMP-9在STEMI患者症状发作4 h内明显升高,在STEMI发作12~24 h后达到峰值且峰值持续72 h ,可作为评价心梗患者风险的指标。

Objective To investigate the significance of the changes on serum Matrix metalloproteinase-9 (MMP-9) in Patients with ST-segment elevation myocardial infarction (STEMI) .Methods A total of 55 STEMI patients admitted into our hospital between September 2011 and February 2012 were recruited . The sampling was collected at six points within 4 h ,4-8 h ,8-12 h ,12-24 h ,24-48 h and 48-72 h of symptom onset .The control groups were fifty subjects of healthy volunteers respectively .The plasma lev-els of MMP-9 in venous blood were detected with enzyme-linked immunosorbent assay (ELISA) .The GRACE risk score was used for risk assessment .Results The MMP-9 level was higher in patients at all six points compared with the control group .The MMP-9 level was significantly higher in patients at 48-72 h (P <0 .05) ,12-24 h (P <0 .05) than within 4 h and the MMP-level at 12-24 h (P <0 .05) ,at 24-48 h (P <0 .05) ,at 48 -72 h (P <0 .05) was significantly higher than 4 -8 h .The MMP-9 level is positive correlated to the GRACE risk score (r = 0 .644 , P <0 .001) .Conclusion The plasma levels of MMP-9 was significantly higher in patients with STEMI within 4 hours of the onset of symptoms .The peak of MMP-9 level was 12-24 hours after onset and the peak lasted for 72 hours .The MMP-9 was an index of assessing the risk of STEMI .
