Cardiac ATP production primarily depends on oxidative phosphorylation in mitochondria and is dynamically regulated by Ca2+ levels in the mitochondrial matrix as well as cytosolic ADP. Here we discuss mitochondrial Ca2+ signaling and its dysfunction which has recently been linked to cardiac pathology including arrhythmia, and heart failure. Similar dysfunction in other excitable and long-lived cells like neurons is associated with neurodegenerative diseases such as Alzheimer’s disease, ALS and Parkinson’s disease. Central to this new understanding is the critical regulation by Ca2+ of both mitochondrial quality control and ATP production. Mitochondrial associated membrane (MAM) signaling from sarcoplasmic and endoplasmic reticulum to mitochondria is discussed. We propose future research directions that emphasize a need to define quantitatively the physiological roles of MAMs, and both mitochondrial quality control and ATP production.
