AIF、Cyt-C、Apaf-1在冠状动脉介入治疗中水平变化的临床研究

目的通过测定冠心病患者介入治疗前后血清中凋亡诱导因子(AIF)、细胞色素C(Cyt-C)、凋亡蛋白酶活化因子(Apaf-1)水平的变化,探讨冠状动脉介入治疗(PCI)对冠心病患者血清中AIF、Cyt-C及Apaf-1水平的影响。方法冠心病介入治疗组(PCI组)36例和单纯冠脉造影组(CAG组)28例,在术前、术后3 h、6 h、12 h、24 h以及48h分别测定血清AIF、Cyt-C及Apaf-1水平。结果术前PCI组与CAG组的AIF、Cyt-C水平差异均有统计学意义,而术前PCI组与CAG组的Apaf-1水平差异无统计学意义。PCI组术后AIF、Cyt-C及Apaf-1水平较术前有升高趋势,在术后12 h达高峰,以后逐渐恢复至基线水平,但各时间点水平差异无统计学意义。CAG组术后血浆AIF、Cyt-C及Apaf-1水平较术前有升高趋势,至术后48 h达到峰值,AIF术后48 h水平与术前相比差异具有统计学意义(P<0.05)。PCI组与CAG组术后各时间点AIF、Cyt-C与Apaf-1水平相比均显著增高,于术后12 h AIF、Cyt-C与Apaf-1水平PCI和CAG两组之间的差异均具有统计学意义,且AIF术后6 h、24 h水平PCI和CAG两组之间的差异均具有统计学意义。结论 PCI可引起血AIF、Cyt-C及Apaf-1水平升高,PCI组术前AIF、Cyt-C及Apaf-1水平明显高于CAG组,提示冠状动脉病变程度与细胞凋亡呈正相关。冠脉介入治疗术后可能出现短暂性心肌缺血,加重了心肌损伤,AIF、Cyt-C及Apaf-1可作为细胞凋亡的监测指标并有助于冠心病患者PCI术后不典型心肌损伤的诊断。AIF可能是反映细胞损伤的敏感指标之一。
