Apoptosis or programmed cell death is increasingly considered to be a major factor in the development and progression of cardiovascular disease. In patients with heart failure the activation of apoptosis may result in the loss of irreplaceable cardiac myocytes promoting the clinical course of the syndrome. Moreover, in the coronary arteries inflammation and apoptosis may weaken critical structures of the vessel wall leading to plaque rupture and, subsequently, to myocardial infarction. Given these deleterious consequences, it seems almost paradoxical that programmed cell death is an active process that, if initiated under physiological circumstances, is essential for both coordinated tissue growth or destruction of malignant cells. This text provides a synopsis of basic mechanisms, cellular and structural targets and, finally, clinical implications of programmed cell death in the heart. The authors of this volume give concise overviews on general and cell-specific aspects of programmed cell death in cardiac myocytes and fibroblasts, as well as in vascular smooth muscle and endothelial cells.Furthermore, novel therapeutic options arising from the outstanding pathophysiological significance of cardiac apoptosis are presented.
