This book aims to present a comprehensive classification of hypertensive phenotypes based on underlying target organ involvement. Particular emphasis is placed on review and assessment of clinical presentation, pathophysiologic mechanisms, and possible specific therapeutic options for each hypertension phenotype. Several of these phenotypes are well known and well described in the literature, such as prehypertension, white coat and masked hypertension, isolated systolic hypertension, renovascular hypertension, endocrine hypertension, pediatric hypertension, and gestational hypertension. Other hypertension phenotypes, however, are not widely recognized, being reported only in special reviews; examples include hypertension associated with renal calculus disease and other rarer causes such as Turner syndrome, herbal and medicinal compounds, and pharmacologic agents. A detailed account of the various causes of monogenic hypertension is also included. Finally, a section is devoted to general aspects of hypertension, including the significance of blood pressure indices, the natural course of untreated and treated hypertension, hypertension mechanisms, genetics, and guidelines for blood pressure control.

Chronic kidney disease is one of the world's major public health problems, and the prevalence of kidney failure is rising steadily. Among the risk factors for a faster progression of renal disease are hypertension and proteinuria, many studies clearly demonstrating that hypertension is both a cause and consequence of chronic kidney disease. Namely, renal blood pressure regulation seems to be involved in five major pathophysiological mechanisms (all closely related to the renin-angiotensin system): Pressure-natriuresis, renal sympathetic nervous system, renal blood flow, intraglomerular pressure and tubuloglomerular feedback. This book reviews experimental data which form the basis of our current understanding of the association between hypertension and kidney diseases: The pathogenesis of increased blood pressure, the mechanisms by which systemic hypertension promotes progressive kidney failure, and the impact of antihypertensive agents on experimental renal mechanisms involved in hypertension. Furthermore, the role of angiotensin II receptor blockers in both the control of systemic blood pressure and the reduction of proteinuria is examined in an attempt to define optimal therapeutic strategies to prevent the otherwise inexorable deterioration of renal function in patients with chronic kidney disease.

The way in which blood pressure is controlled is not well understood. I offer as evidence the spirited debates among scientists that have occurred in the past and that will probably continue for some time to come. Consider also that hypertension is a disease of significant morbidity and mortality, yet in the majority of instances the cause of the pressure elevation is unknown. And further, the wide variety of antihypertensive drugs currently used, often without a full understanding of the mechanisms involved, suggests that we often know as little about what decreases blood pressure with antihypertensive therapy as we know about what increases pressure in the first place. This ignorance has fostered and probably justified extensive inquiries into outstanding problems of blood pressure control. The pace has quickened in the last one or two decades, and published reports germaine to the subject appear to be accumulating at an exponential rate. Hence, speaking for myself, the reviewer is faced with too little understanding and too much information.

There is clear evidence that in severe hypertension lowering blood pressure, by drug therapy decreases the incidence of major cardiovascular events. Recent studies suggest that such benefit may also extend to patients with mild to moderate hypertension. The putative benefits of drugs may be offset, however, by their adverse effects and a prime example is the increased incidence of impotence and metabolic disorders in patients on thiazide diuretics. There is, therefore, a real need to look further into the therapy of patients with mild to moderate hypertension. The ideal drug in such patients would oppose the basic mechanisms responsible for the elevation in blood pressure, would prevent counter-regulatory responses and would have minimal side-effects in both the short-term and the long-term, the latter being of particular importance to younger patients. These aspects were considered at the symposium "Mild hypertension. Current con troversies and new approaches" held at Titisee in West Germany, October 13-15 in 1983. The foundation for discussion was set with an exposition of the neural and hormonal regulation of blood pressure in normal man followed by a consideration of the pos~ible pathophysiological mechanisms involved in patients with hypertension. Particular at tention was focused on the central nervous system and on effects governed by activity of the peripheral nervous system as these may well provide further opportunities for logical therapeutic intervention in clinical hypertension. The current management of mild to moderate hypertension was then reviewed.

This book is an attempt to indicate to researchers and clinicians a simple way to approach the complexity of cardiovascular neural regulation. A conceptual pillar like homeostasis is contrasted with instability and a continuous interaction of opposing mechanisms that have negative and positive feedback characteristics, and is considered to subserve the multitude of patterns pertaining to physiology. However, in pathophysiological conditions the final design is most often replaced by largely purposeless neural mechanisms. The complexity of cardiovascular neural regulation, reflected by the state of sympathovagal balance, is also assessed in the frequency domain. Power spectrum analysis of heart rate and arterial pressure variability, a sophisticated but simply explained approach, provides an unprecedented tool to evaluate this interaction in both physiological and pathophysiological conditions. The elementary characteristics of nonlinear dynamics are also outlined. Finally, the need for an ethical structure for science and medicine is analyzed.

The fundamental fault in hypertension is unknown. Calling it a fundamental fault, indeed, tacitly begs the question: Is there one fundamental fault, or are there several that are interlinked or interdependent? A simple yes or no answer cannot be offered. This volume is not designed to survey the up-to-date recent advances in research on hypertension, nor intended to provide provisional an swers to the so many unknowns in this topic. It is, in fact, an attempt to articulate questions that are worth asking, given the license of an unhibited, albeit disci plined, inquiry. The range of expression varies from dogmatic opinion to a declared speculation. Is the primary abnormality an excessive sodium and reduced potassium intake over generations? Or is it hormonal excess, deficiency, imbalance or altered synthesis of abnormal forms? Does the nervous system playa role of active initiation or only of passive maintenance in the genesis of hypertension? Is the heart only a pump acting in concert with the happenings to the vasculature trying to provide adequate flow in the face of vasconstriction induced by neural or humoral factors, or does it sometimes become the culprit by pumping blood flow in excess of demand and thus initiating hypertrophic changes in blood vessels, or by assuming the role of an endocrine organ and being the source of a hormone with influence on cellular transport of sodium and on vasomotor tone? Is an elusive and mysterious fault in the kidney, the primary basis of all of the above
