Ketones in Cardiovascular Health and Disease: An Updated Review

Le résumé fourni par la source

Ketones are metabolites primarily produced by the liver and are utilized by various organs outside of the liver. Recent advances have demonstrated that ketones serve not only as alternative energy sources but also as signaling molecules. Research indicates that ketones can influence cancer development and metastasis, cardiac metabolic and structural remodeling, physical performance, vascular function, inflammation, and the aging process. Emerging evidence from preclinical and early-phase clinical studies suggests that strategies such as ketone salts, ketone esters, and the ketogenic diet may offer therapeutic benefits for conditions like heart failure, acute cardiac injury, diabetic cardiomyopathy, vascular complications, atherosclerosis, hypertension, and aortic aneurysm. This literature review updates the current understanding of ketone metabolism and its contributions to cardiovascular health and diseases. We highlight the underlying molecular mechanism with post-translational modification known as β-hydroxybutyrylation, which affects the fate and function of target proteins. Additionally, we discuss the therapeutic challenges associated with ketone therapy, the potential of using ketone levels as biomarkers for cardiovascular diseases, as well as gender- and age-specific differences in ketone treatment. Finally, we explore future research directions and what is needed to translate these new insights into cardiovascular medicine.
