摘要 目的对比药物治疗与择期冠状动脉介入治疗(PCI)对急性心肌梗死(AMI)后心肌细胞外基质重塑的影响。方法将41例AMI患者分成两组,药物治疗组给予优化达标的内科药物治疗,择期PCI组在优化达标的内科药物治疗基础上行择期PCI治疗。应用酶联免疫法检测两组发病1周及6、12、24个月时的血清基质金属蛋白酶-1(MMP-1)、基质金属蛋白酶组织抑制剂(TIMP-1)、Ⅰ型前胶原羧基端肽(PⅠCP)及Ⅲ型前胶原(PCⅢ)水平。结果与对照组比较,药物治疗组与择期PCI组MMP-1各亚组均显著降低;TIMP-1在1周及6个月时较对照组显著降低,药物治疗组的TIMP-1在12个月时较6个月显著升高,择期PCI组TIMP-1在6个月时较同期药物治疗组显著升高;药物组与PCI组各时点PⅠCP水平及PCⅢ水平均较对照组显著升高(P均<0.05),两组AMI后6个月内均逐渐升高,至12个月呈下降趋势;PCI组6个月时PⅠCP水平与药物组同时点相比均显著降低(P<0.05)。结论 AMI后发生心肌细胞外基质重塑,其可被药物和择期PCI抑制;从抑制胶原合成代谢亢进及原有胶原网络降解的角度而言,择期PCI在AMI后6个月内明显优于药物治疗,而12~24个月时择期PCI未进一步显示出此方面的优越性,故对于未实施PCI而临床状况又稳定的AMI患者应立足于优化达标的内科药物治疗。
