Sepsis-induced cardiomyopathy is a reversible non-ischemic acute cardiac dysfunction associated with sepsis. It is strongly associated with an abnormal immune response. It emerges as a vital threat to public health owing to its high mortality rate. However, the exact pathogenesis requires further investigation. In recent years, NETosis and ferroptosis, which are novel modes of programmed cell death, have been identified and found to play important roles in sepsis-related organ damage. This article outlines the mechanisms of these two modes of cell death, discusses the role of neutrophil extracellular traps in myocardial injury and the importance of ferroptosis in sepsis-induced cardiomyopathy, and reviews the potential interconnection between these two types of programmed cell death in sepsis-induced cardiomyopathy.
脓毒症诱导的心肌病是一种与脓毒症相关的可逆性非缺血性急性心脏功能障碍。它与异常免疫反应密切相关。由于其高死亡率,它已成为对公众健康的重大威胁。然而,确切的发病机制仍需进一步研究。近年来,已确定并发现程序性细胞死亡的新模式——中性粒细胞胞外陷阱形成(NETosis)和铁死亡在脓毒症相关器官损伤中起重要作用。本文概述了这两种细胞死亡模式的机制,讨论了中性粒细胞胞外陷阱在心肌损伤中的作用以及铁死亡在脓毒症诱导的心肌病中的重要性,并综述了这两种程序性细胞死亡在脓毒症诱导的心肌病中可能的相互联系。
