Peroxynitrite is a potent oxidant that is quickly emerging as a crucial modulator of myocardial function. This review will focus on the regulation of myocardial contraction by peroxynitrite during health and disease, with a specific emphasis on cardiomyocyte Ca2+ handling, proposed signaling pathways, and protein end-targets.
Keywords: myocyte, peroxynitrite, nitric oxide synthase, Ca2+, cAMP-dependent protein kinase, protein phosphatase 2a
