Abstract:
Myocardial substrate metabolism is severely impaired after heart failure, and the selection and utilization of substrates, such as glucose and fatty acids, are remodeled, resulting in insufficient myocardial productivity, cardiac dysfunction and progressive left ventricular remodeling. It is believed traditionally that the heart changes from fatty acid metabolism to glucose metabolism during heart failure, which however is contradictory with some findings in recent years. No consistent conclusion can be drawn from studies on the changes of myocardial energy substrate metabolism and its regulatory mechanism after heart failure. Metabolic treatment for heart failure has developed slowly. Therefore, it is necessary to explore the reasons for heterogeneity of these conclusions for defining the metabolic patterns of heart failure substrates and developing metabolically targeted drugs. This review summarizes the metabolic patterns and regulatory mechanisms of normal myocardium under physiological conditions, focuses on the elaboration and comparison of myocardial substrates metabolic abnormalities in heart failure induced by ischemic heart disease, pressure load, volume load and dilated cardiomyopathy in such aspects as etiology, severity, duration of heart failure, species studied, animal models and metabolic detection methods, and makes a preliminary analysis on the consistency and differences of relevant conclusions in various studies, and discusses the future trend of metabolic treatment, with the aim to summarize the rules and molecular mechanism of glucose metabolism and fatty acid metabolism after heart failure and provide clues for the research of metabolic targeted therapy.
