简介：目的:探讨血清转化生长因子(TGF-β1)和胰岛素样生长因子(IGF-1)水平对冠心病患者心功能的影响.方法:选择因胸痛住院患者88例分为急性心肌梗死(AMI)组、心绞痛(AP)组和对照组,填调查表,入院择日行选择性冠状动脉造影术,术前采股动脉血,以ABC双抗体夹心ELISA法检测血清TGF-β1和IGF-1浓度,入院2周内完成超声心动图,所有资料用SPSS10.0软件处理.结果:AMI患者与AP患者相比,血清TGF-β1浓度较低(P<0.05),IGF-1血清浓度较低(P<0.001);冠心病患者血清IGF-1水平与EF(P<0.05)和FS(P<0.02)正相关.结论:TGF-β1和IGF-1对冠心病患者具有某种保护作用,其中IGF-1能保护冠心病患者的心功能.
