Energy metabolism homeostasis in cardiovascular diseases

Area of Science:

• Cardiovascular Science
• Metabolic Biology
• Cardiac Physiology

Background:

• Cardiovascular disease (CVD) is a primary cause of death globally.
• Disturbances in energy metabolism are early indicators in various CVDs, including coronary heart disease, diabetic cardiomyopathy, and heart failure.
• Understanding myocardial metabolism is crucial for elucidating CVD pathophysiology.

Purpose of the Study:

• To explore the role of myocardial energy homeostasis disturbance in cardiovascular diseases.
• To summarize lipid and glucose metabolism in the heart.
• To investigate metabolic regulation in neonatal and aging hearts and propose mechanisms for cardiac regeneration and degeneration.

Main Methods:

• Literature review and synthesis of current research on cardiac metabolism.
• Analysis of metabolic regulation during different life stages (neonatal, aging).
• Overview of molecular networks linking cardiac proliferation, regeneration, and metabolic dysfunction.

Main Results:

• Lipid metabolism/lipotoxicity and glucose metabolism/insulin resistance are key aspects of cardiac energy homeostasis.
• Metabolic regulation differs significantly between neonatal and aging hearts.
• Emerging molecular networks highlight the interplay between cardiac proliferation, regeneration, and metabolic disturbances.

Conclusions:

• Myocardial energy metabolism plays a critical role in the development and progression of cardiovascular diseases.
• Novel therapeutic targets for CVDs may arise from understanding cardiac metabolic regulation and regeneration pathways.
• Further research into the molecular networks governing cardiac metabolism holds promise for a new era in CVD treatment.
