An overview of all the available literature on the various aspects of the regulation of the cardiovascular system's function and physiology by the adrenergic neurohormonal system, i.e. the catecholamines norepinephrine and epinephrine. Although there are several books describing the adrenergic system's biology, physiology and pharmacology, and also several excellent books on cardiovascular physiology and pathology, this book focuses exclusively on the interface of these two areas: cardiovascular regulation by the adrenergic system and how it affects cardiovascular diseases and their treatments. Each chapter describe the roles of the adrenergic system first in each cardiovascular cell type (cell type-by-cell type) and then in specific areas of cardiovascular physiology, such as in exercise and in cardiovascular metabolism. Finally, the book concludes with a chapter on the adrenergic system's role in the currently very “hot” (in terms of scientific investigations) area of cardiovascular stem cell biology. The book covers the adrenergic system—specifically and exclusively in the heart and vessels. It is formatted by cardiovascular cell type-by-cell type manner, rather than in an organ-by-organ or in a disease-by-disease manner, as usually discussed in standard, conventional biomedical textbooks. The book also discusses the adrenergic system in novel, cutting-edge cardiovascular research areas, in which it has not been covered well so far (e.g. stem cells, exercise). These three areas constitute the most important assets of the book, which sets it apart from others in the field.
