The myocardium is metabolically flexible, however, impaired flexibility is associated with cardiac dysfunction in conditions including diabetes and heart failure. The mitochondrial pyruvate carrier (MPC) complex, composed of MPC1 and MPC2, is required for pyruvate import into the mitochondria. Here we show that MPC1 and MPC2 expression is downregulated in failing human and mouse hearts. Mice with cardiac-specific deletion of MPC2 (CS-MPC2−/−) exhibited normal cardiac size and function at 6-weeks old, but progressively developed cardiac dilation and contractile dysfunction, which was completely reversed by a high fat, low carbohydrate “ketogenic diet.” Diets with higher fat content, but enough carbohydrate to limit ketosis, also improved heart failure, while direct ketone body provisioning provided only minor improvements in cardiac remodeling in CS-MPC2−/− mice. An acute fast also improved cardiac remodeling. Together, our study reveals a critical role for mitochondrial pyruvate utilization in cardiac function, and highlights the potential of dietary interventions to enhance cardiac fat metabolism to prevent or reverse cardiac dysfunction and remodeling in the setting of MPC-deficiency.
