摘要
目的探讨经皮冠状动脉介入治疗术后(Percutaneouscoronaryintervention,PCI)后患者血清血管内皮生长因子(Endothelialgrowthfactor,VEGF)的变化规律及其与再狭窄的关系。方法采用双抗夹心酶联免疫吸附法检测45例冠心病组和15例对照组血清VEGF浓度,用免疫投射比浊法测定冠心病组血清C反应蛋白(Cresponseprotein,CRP)。结果冠心病组手术前血清VEGF水平显著高于对照组(P<0.01,冠心病组术后1、3dVEGF、CRP水平均较术前明显升高(P<0.01),术后第3天血清VEGF达最高水平,且升高的水平与术后第3天的CRP升高水平呈正相关(r=0.58,P<0.01)。手术后第7天,血清VEGF水平较术前显著降低(P<0.01),与对照组比较,无显著性差异(P=0.551)。冠心病组有38例患者复查了冠状动脉造影,平均获得血管内径丢失指数(28.72±8.56)%,再狭窄8例。术后第7天血清VEGF水平与血管的直径丢失呈负相关(r=-0.87,P<0.01)。再狭窄亚组术后第7天血清VEGF水平较非再狭窄组低(P<0.01)。结论VEGF可能是反应心肌缺血指标,冠状动脉介入治疗后前3d血清VEGF的增高,可能是对介入治疗后血管损伤的反应。术后血清VEGF高水平表达可能对冠状动脉介入治疗术后再狭窄有抑制作用。术后第7天的血清VEGF可以作为再狭窄的预测指标之一。
