Nitric oxide (NO) influences many aspects of cardiac function including excitation–contraction coupling, myofilament function, oxygen consumption, substrate metabolism, and cell growth and survival [1,2]. All three NO synthase (NOS) isoforms, namely eNOS, nNOS, and iNOS, can be expressed in the heart. An important paradigm with respect to the cardiomyocyte has been the demonstration that eNOS and nNOS are both expressed in this cell type but have distinct effects on contractile function as a result of their specific subcellular localization and distinct interactions with and/or proximity to other
