With its complicated pathobiology and pathophysiology, heart failure (HF) remains an increasingly prevalent epidemic that threatens global human health. Ferroptosis is a form of regulated cell death characterized by the iron-dependent lethal accumulation of lipid peroxides in the membrane system and is different from other types of cell death such as apoptosis and necrosis. Mounting evidence supports the claim that ferroptosis is mainly regulated by several biological pathways including iron handling, redox homeostasis, and lipid metabolism. Recently, ferroptosis has been identified to play an important role in HF induced by different stimuli such as myocardial infarction, myocardial ischemia reperfusion, chemotherapy, and others. Thus, it is of great significance to deeply explore the role of ferroptosis in HF, which might be a prerequisite to precise drug targets and novel therapeutic strategies based on ferroptosis-related medicine. Here, we review current knowledge on the link between ferroptosis and HF, followed by critical perspectives on the development and progression of ferroptotic signals and cardiac remodeling in HF.
心力衰竭(HF)的发病机制复杂,其患病率不断上升,已成为威胁全球人类健康的重大公共卫生问题。铁死亡是一种受调控的细胞死亡形式,其特征是细胞膜系统中铁依赖性脂质过氧化物的累积,与细胞凋亡、坏死等其他类型的细胞死亡不同。越来越多的证据支持这样一种观点,即铁死亡主要受铁代谢、氧化还原平衡和脂质代谢等几种生物途径的调节。最近,铁死亡被确定在不同刺激引起的心力衰竭(如心肌梗死、心肌缺血再灌注、化疗等)中发挥重要作用。因此,深入探讨铁死亡在心力衰竭中的作用具有重要意义,这可能是基于铁死亡相关药物的精准药物靶点和新型治疗策略的前提。本文就铁死亡与心力衰竭的关系进行综述,并对心力衰竭中铁死亡信号的发展和进展以及心脏重构进行了批判性的探讨。
