Calcium (Ca2+) is a universal second messenger involved in the regulation of various cellular processes, including electrical signaling, contraction, secretion, memory, gene transcription, and cell death. In heart, Ca2+ governs cardiomyocyte contraction, is central in electrophysiological properties, and controls major signaling pathway implicated in gene transcription. How cardiomyocytes decode Ca2+ signal to regulate gene expression without interfering with, or being controlled by, "contractile" Ca2+ that floods the entire cytosol during each heartbeat is still elusive. In this review, we summarize recent findings on nuclear Ca2+ regulation and its downstream signaling in cardiomyocytes. We will address difficulties in reliable quantification of nuclear Ca2+ fluxes and discuss its role in the development and progression of cardiac hypertrophy and heart failure. We also point out key open questions to stimulate future work.
