The vascular endothelium has become an increasing focus of research over the last 15 years. Nitric oxide and endothelin appear to have important and opposing actions on vascular tone, smooth muscle proliferation and platelet/monocyte activation, and endothelial dysfunction affecting the L-arginine/nitric oxide and endothelin systems both appear to be crucial to atherogenesis and to the pathophysiology of many forms of cardiovascular disease. Additionally, a number of new drugs of major clinical interest are now emerging that act favourably to modulate endothelial function and alter the outcome in these conditions. Here, a synthesis of the current understanding of endothelial dysfunction in hypertension and related disorders - and future therapeutic prospects - has been drawn together by a series of internationally recognised leaders in the field.

The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells. The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation of immunology, inflammation and angiogenesis, and an important metabolizing and an endocrine organ. Endothelial cells controls vascular tone, and thereby blood flow, by synthesizing and releasing relaxing and contracting factors such as nitric oxide, metabolites of arachidonic acid via the cyclooxygenases, lipoxygenases and cytochrome P450 pathways, various peptides (endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine, purines, reactive oxygen species and so on. Additionally, endothelial ectoenzymes are required steps in the generation of vasoactive hormones such as angiotensin II. An endothelial dysfunction linked to an imbalance in the synthesis and/or the release of these various endothelial factors may explain the initiation of cardiovascular pathologies (from hypertension to atherosclerosis) or their development and perpetuation.

The field of pediatric hypertension has undergone important changes in the time since the second edition of Pediatric Hypertension published. Much new information on hypertension in the young has become available. Previous chapters have been fully revised and new chapters have been added to cover important topics of recent interest such as consensus recommendations, the prevalence of hypertension in the young due to the obesity epidemic, studies of antihypertensive agents, and ambulatory blood pressure monitoring. Pediatric Hypertension, Third Edition is a comprehensive volume featuring 38 chapters covering the breadth of the current knowledge. It is divided into four sections: Regulation of Blood Pressure in Children; Assessment of Blood Pressure in Children: Measurement, Normative Data, Epidemiology; and Hypertension in Children: Predictors, Risk Factors, and Special Populations; Evaluation and Management of Pediatric Hypertension. Filled with the most up-to-date information, Pediatric Hypertension, Third Edition is an invaluable resource for clinicians and researchers interested in childhood hypertension.

The opening chapter of this book, by scientist Dr. Robert Furchgott, details the discovery of endothelium’s role in the vasodilator effect of acetycholine in 1978. Its subsequent identification as nitric oxide has been critical to cardiovascular medicine in understanding the regulation of vascular homeostasis. This simple observation won Dr. Furchgott a Nobel Prize in 1998. Spanning from these initial observations to recent clinical investigations, this work offers an invaluable historical reference and clinical explanation about the intracellular mechanisms that regulate and stimulate endothelial nitric oxide synthase (eNOS). The basic mechanisms leading to endothelial dysfunction in cardiovascular disease complement information about the biological role and regulation of endothelial nitric oxide. Clinical studies of impaired endothelial function in patients with different cardiovascular conditions also reveal important and effective therapeutic strategies. Written for both established physicians and scientists investigating the basic mechanisms and treatment of cardiovascular disease, as well as medical students who want to initiate themselves in the study of endothelial regulation of vascular physiology, many will find this comprehensive review a stimulus for new research.

As the first primer on the effects of exercise on human hypertension, Effects of Exercise on Hypertension: From Cells to Physiological Systems provides the state-of-the-art effects of exercise on the many possible mechanisms underlying essential hypertension in humans. The book contains chapters by distinguished experts on the effects of exercise on physiological systems known to be involved in hypertension development and maintenance as well as less well known aspects of hypertension such as 24-hour ambulatory blood pressure profile and oxidative stress. An emerging area, the effects of resistance exercise training on blood pressure is also covered. A unique aspect of the book is that it covers the effects of exercise mimetics on vascular cell adaptations in order to begin to elucidate some of the cellular mechanisms that may underlie blood pressure reductions with exercise training. Lastly, the book will end with a chapter on the interactive effects of genes and exercise on blood pressure. Chapters are grouped by physiological system or mechanism. The text begins with two overview chapters; one on the general effects of aerobic exercise training and the second on the general effects of resistance exercise training on blood pressure. Each chapter begins with a bulleted list of key points. Effects of Exercise on Hypertension: From Cells to Physiological Systems will be of great value to professional individuals in cardiovascular medicine, the cardiovascular sciences, allied health care professionals, and medical and graduate students in the cardiovascular sciences and medicine.

Hypertension is defined by an increase in systemic blood pressure above limits considered normal, currently set at 140 mmHg for systolic and 90 mmHg for diastolic pressure. Assuming central venous pressure to be near zero, mean arterial pressure is determined by the product of total peripheral resistance and cardiac output. In most cases of essential hypertension, as well as in animal models of hypertension, cardiac output and its main determinants, stroke volume and heart rate, are normal, whereas total peripheral resistance is increased. Total peripheral resistance is influenced by a number of factors described by the Poiseuille’s law, the most significant of which by far is the diameter of blood vessels of the arterial tree. Since blood vessel diameter is a reflection of both vascular structure and active regulation of vascular tone through mechanisms of vasoconstriction and vasodilatation, it is generally considered that alterations in total peripheral resistance are directly determined by alterations in vascular smooth muscle structure and/or function. Thus, complex blood pressure regulation systems, including renal, nervous, endocrine, immune, and others, in their turn influenced by genetic or environmental factors, converge upon the same molecular mechanisms that control the structure and function of vascular smooth muscle. In this work, rather than providing the exhaustive list of modifications in the blood pressure regulating systems that ultimately affect the vasculature in hypertension, we will focus on the structural and functional alterations of vascular smooth muscle per se during hypertension.
