Metabolic cardiology is a new field of medicine which concentrates on the prevention, management, and treatment of cardiovascular disease at the cellular level, through biochemical interventions that are native to the human body. Diseased hearts are energy-starved, which means they lack enough adenosine triphosphate (ATP) to fuel healthy cardiac function. ATP molecules are both synthesized and recycled within the body, and supply all of the body’s energy. Metabolic cardiology aims to build up and maintain ATP stores in the heart, and ultimately enhance heart health, by providing the body with the nutrients it needs to make ATP.
