摘　　要：细胞衰老被定义为不可逆的细胞周期停滞,其特征在于基因和蛋白质表达的显著改变以及衰老相关分泌表型的产生。心肌梗死后的心肌中血流需求和供应之间严重失衡可导致细胞应激性衰老的发生,其在决定心肌梗死后心脏功能转归中发挥重要作用。现主要对细胞应激性衰老在心肌梗死后维持心脏功能中的作用及机制,以及针对细胞衰老开发的药物对心肌梗死后心脏功能的影响等进行综述,为通过调节细胞衰老而改善心肌梗死的治疗提供一些新的思路。Cell senescence is defined as irreversible cell cycle arrest characterized by significant alterations in gene and protein expression and the production of senesence-associated secretory phenotype.A severe imbalance between blood flow demand and supply in the myocardium after myocardial infarction can lead to the occurrence of stress-induced premature senescence,which plays an important role in determining cardiac function outcomes after myocardial infarction.This article mainly reviews the role and mechanism of stress-induced premature senescence in maintaining cardiac function in myocardial infarction,as well as the effect of drugs developed for cell senescence on cardiac function after myocardial infarction,so as to provide some new ideas for the treatment of myocardial infarction by regulating cellular senescence.
