Metabolic reprogramming in cancer therapy-related cardiovascular toxicity: Mechanisms and intervention strategies

Cancer therapy-related cardiovascular toxicity (CTR-CVT) poses a major challenge in managing cancer patients, contributing significantly to morbidity and mortality among survivors. CTR-CVT includes various cardiovascular issues, such as cardiomyopathy, myocardial ischemia, arrhythmias, and vascular dysfunction, which significantly impact patient prognosis and quality of life. Metabolic reprogramming, characterized by disruptions in glucose, lipid, and amino acid metabolism, represents a shared pathophysiological feature of cancer and cardiovascular diseases; however, the precise mechanisms underlying CTR-CVT remain inadequately understood. In recent years, strategies targeting metabolic pathways have shown promise in reducing cardiovascular risks while optimizing cancer treatment efficacy. This review systematically summarizes metabolic reprogramming characteristics in both cancer and cardiovascular diseases, analyzes how anticancer therapies induce cardiovascular toxicity through metabolic alterations, and explores emerging therapeutic strategies targeting metabolic dysregulation. By integrating current research advancements, this review aims to enhance the understanding of CTR-CVT and provide groundwork for the development of safer and more effective cancer approaches.
