摘　　要：代谢相关脂肪性肝病(MAFLD)被认为是一种多系统疾病,可导致多种肝外并发症,其中心血管疾病(CVD)是MAFLD患者最常见的死亡原因。MAFLD与其并发症有许多共同的代谢危险因素,通过炎症、内皮功能障碍、氧化应激、胰岛素抵抗和脂质代谢异常等机制,增加糖尿病、高血压、动脉粥样硬化、静脉血栓形成等的易感性,与MAFLD的病理之间存在复杂的相互作用,促进彼此的发生。在MAFLD进展过程中,肝脏微血管的各个部分都可能发生变化,导致肝脏微循环障碍,肝内微血管紊乱和微循环功能障碍是肝外并发症发展的关键,但MAFLD仍未像其他传统风险因素一样被重视。深入了解MAFLD中微血管系统病理改变与微循环障碍之间的联系,有助于MAFLD肝外并发症的机制研究和治疗,更重要的是让MAFLD患者更加重视肝脏以外的保健治疗。Metabolic associated fatty liver disease(MAFLD)is considered a multisystem disease that can lead to multiple extrahepatic complications,among which cardiovascular disease(CVD)is the most common cause of death in MAFLD patients.MAFLD and its complications share many common metabolic risk factors,which increase the susceptibility to diabetes,hypertension,atherosclerosis,and venous thrombosis through the mechanisms such as inflammation,endothelial dysfunction,oxidative stress,insulin resistance,and abnormal lipid metabolism,and there is a complex interaction between such factors and the pathology of MAFLD,thereby promoting the occurrence of each other.During the progression of MAFLD,there might be changes in various parts of the liver microvasculature,resulting in hepatic microcirculation disturbance,and intrahepatic microvascular disturbance and microcirculation dysfunction are the key to the progression of extrahepatic complications,but MAFLD has not yet been taken seriously like other traditional risk factors.An in-depth understanding of the association between pathological changes of the microvasculature and microcirculation disturbance in MAFLD will help with the mechanism research and treatment of the extrahepatic complications of MAFLD,and more importantly,help MAFLD patients pay more attention to healthcare outside the liver.
