Cardiac myocytes can undergo programmed cell death in response to a variety of insults and apoptotic elimination of myocytes from the adult myocardium can lead directly to cardiomyopathy and death. Although it remains to be shown that therapy specifically targeting apoptosis will improve the prognosis of ischemic heart disease or heart failure, a number of studies in the past year have shed light on potential ways to intervene in the process. Progress in the past year includes a better understanding of the importance of mitochondria-initiated events in cardiac myocyte apoptosis, of factors inducing apotosis during hypoxia, and of the dual pro-apoptotic and anti-apoptotic effects of hypertrophic stimuli such as β-adrenoceptor agonists, nitric oxide and calcineurin. Further evidence supports the pathophysiologic relevance of apoptosis in human heart disease. The tracking of cytoprotective and apoptotic signal transduction pathways has revealed important new insights into the roles of the mitogen-activated protein (MAP) kinases p38, extracellular signal regulated kinase (ERK) and c-Jun N-terminus kinase (JNK) in cardiac cell fate.
