摘　　要：冠状动脉微血管功能障碍和阻塞(CMVO)存在于近半数急诊经皮冠状动脉介入治疗成功的患者中,且与不良预后相关。缺血再灌注损伤、远端栓塞和个体微循环相互作用导致CMVO发生。红细胞是人体中最丰富的血细胞,通常占血容量的35%~45%,它们不仅参与气体交换的过程,还通过调节一氧化氮代谢和释放ATP调节心血管功能,在CMVO发展中发挥重要作用。现对红细胞在急性心肌梗死相关冠状动脉微血管功能障碍中的研究进展进行综述。Coronary microvascular dysfunction and obstruction(CMVO)is present in nearly half of patients with successful initial percutaneous coronary intervention and is associated with a poor prognosis.Interacting mechanisms cause CMVO in humans:ischemia-reperfusion injury,distal embolization,and individual susceptibility to the microcirculation.Red blood cells are the most abundant blood cells in the body,typically accounting for 35%to 45%of blood volume,and play an important role in the development of CMVO not only by participating in the process of gas exchange,but also by regulating nitric oxide metabolism and releasing ATP to regulate cardiovascular function.This article reviews the progress of research on erythrocytes in coronary microvascular disorders associated with acute myocardial infarction.
