Abstract: Heart failure represents a significant global public health issue, intricately connected to the dynamics of cardiac energy metabolism. Within this critical biological process, mitochondria emerge as central figures, not merely as the main source of energy for the heart but also as key players in ensuring the vitality and functionality of cardiac cells. This article offers a detailed examination of mitochondrial energy metabolism, highlighting the structural attributes of mitochondria, their functional significance, and their indispensable role in the cardiac energy supply network. Additionally, we probe into the molecular intricacies underlying the disruption of mitochondrial energy metabolism in heart failure, spotlighting the adverse effects of oxidative stress-induced mitochondrial damage, alterations in mitochondrial dynamics, and the consequential role of mitochondrial autophagy in heart failure scenarios. Furthermore, this review sheds light on mitochondrial-centric therapeutic strategies for heart failure management, including protective measures for mitochondria, pharmacological interventions aimed at rejuvenating mitochondrial function, and the advancement of novel treatment modalities and clinical trials. Looking ahead, the article underscores the critical need for further investigation into the interplay between mitochondrial dynamics and heart failure, the pursuit of innovative therapeutic targets, and the cultivation of personalized treatment methodologies. In essence, this review lays out a fresh perspective on the pathophysiological underpinnings of heart failure and carves out a roadmap for future therapeutic research endeavors.
