心肌梗死后,心肌细胞永久性丢失。且成熟心肌不可再生,不可能通过分裂增殖来弥补病理性细胞数量减少。虽然近来有研究证实在心肌梗死后梗死区边缘有少量心肌细胞发生有丝分裂,但这种分裂十分微弱,根本不足以代偿有临床意义的坏死心肌。现有治疗手段也无法促使心肌再生。因此,使 Myocardial cells are permanently lost after myocardial infarction. And mature myocardium can not be regenerated, it is impossible to make up the number of pathological cells by dividing and multiplying. Although recent studies have shown that there is a small amount of myocardial cell mitosis at the edge of the infarct zone after myocardial infarction, the split is very weak and simply not enough to compensate for clinically significant necrotic myocardium. The existing treatment can not promote myocardial regeneration. So make it
