Book Description
Hypertension remains the leading cause of cardiovascular morbidity and mortality in spite of current medical therapies. It has been estimated that 50% of Western civilization has hypertension and approximately 20% of patients have resistant hypertension. Renal denervation (RDN) is a minimally invasive, endovascular catheter based procedure using radiofrequency ablation aimed at treating resistant hypertension. Early studies show a high degree of effectiveness in renal denervation to treat hypertension. This book examines renal pathophysiology and the rationale for renal denervation, as well as possible long term benefits and risks of this new therapy. The myriad of devices involved in the evolution of this therapy are discussed and the book concludes with analyses of the cost effectiveness and future applications.

Book Description
Since the discovery of blood pressure by Stephen Hales in 1733, scientific interest in blood pressure regulation, particularly in hypertensive population, has not lost its popularity. The importance of the interactive effects of blood pressure shifts in different clinical conditions is well understood. We know many contributing factors regulate the pressure of the blood within the arteries. However, crucial blood pressure control and the exact mechanisms involved are still under debate. The present book aims to cover blood pressure from its measurement to various factors of its control with valuable contributions from different authors, in the light of contemporary data, from bench to bed.

Book Description
A growing number of people suffer from so-called resistant hypertension, that is to say, high blood pressure that does not respond to treatment. This disorder is of great current interest and importance for public health, being a common clinical problem faced by both primary care clinicians and specialists. Furthermore, as older age and obesity are among the strongest risk factors for uncontrolled hypertension, the incidence of resistant hypertension will likely increase as the population becomes more elderly and heavier. While the prognosis of resistant hypertension is unknown, cardiovascular risk is undoubtedly increased since patients often have a history of long-standing, severe hypertension complicated by multiple other cardiovascular risk factors. This volume, compiled by a panel of world-renowned experts, offers a comprehensive exploration of resistant hypertension, covering epidemiology, complex diagnostic aspects, and the therapeutic options currently available, with due attention to overall treatment strategies. New therapeutic agents and procedures, such as renal denervation and baroreceptor stimulation, are also described. In addition, the book addresses the economic aspects of resistant hypertension and the role of the different professional figures, from GPs to hypertension specialists, in dealing with it.

Book Description
Diabetes and hypertension have evolved as two of the modern day epidemics affecting millions of people around the world. These two common co-morbidities lead to substantial increase in cardiovascular disease, the major cause of morbidity and mortality of adults around the world. In Diabetes and Hypertension: Evaluation and Management, a panel of renowned experts address a range of critical topics -- from basic concepts in evaluation and management of diabetes and hypertension, such as dietary interventions, to evaluation and management of secondary hypertension in clinical practice. Other chapters focus on high cardiovascular risk populations such as those with coronary heart disease, chronic kidney disease and minority patients. In addition, evolving concepts and new developments in the field are presented in other chapters, such as prevention of type 2 diabetes and the epidemic of sleep apnea and its implication for diabetes and hypertension evaluation and management. An important title covering two of the most troubling disorders of our time, Diabetes and Hypertension: Evaluation and Management will provide the busy practitioner with cutting edge knowledge in the field as well as practical information that can translate into better care provided to the high-risk population of diabetics and hypertensive patients.

Book Description
Sympathetic overactivity is associated with the development of hypertension. Renal denervation (RDN) prevents or delays hypertension in a variety of animal models, which laid the groundwork for the introduction of RDN as a clinical therapy in humans. In 2007, a novel, minimally invasive RDN ablation catheter was first trialled in hypertensive patients, with a 93% success rate of lowering blood pressure for at least three years post-RDN. However, a large scale, sham-controlled clinical trial (Symplicity HTN -3) failed to show reductions in BP greater than sham. The aim of this research topic was to evaluate the efficacy and safety of RDN, to explore the contribution of both afferent and efferent renal nerve activity to hypertension and non-hypertension disorders, and to stimulate future research to better understand the function of the renal nerves and the effects of RDN by highlighting gaps in knowledge.

Book Description
The kidney is innervated with efferent sympathetic nerve fibers reaching the renal vasculature, the tubules, the juxtaglomerular granular cells, and the renal pelvic wall. The renal sensory nerves are mainly found in the renal pelvic wall. Increases in efferent renal sympathetic nerve activity reduce renal blood flow and urinary sodium excretion by activation of α1-adrenoceptors and increase renin secretion rate by activation of β1-adrenoceptors. In response to normal physiological stimulation, changes in efferent renal sympathetic nerve activity contribute importantly to homeostatic regulation of sodium and water balance. The renal mechanosensory nerves are activated by stretch of the renal pelvic tissue produced by increases in renal pelvic tissue of a magnitude that may occur during increased urine flow rate. Activation of the sensory nerves elicits an inhibitory renorenal reflex response consisting of decreases in efferent renal sympathetic nerve activity leading to natriuresis. Increasing efferent sympathetic nerve activity increases afferent renal nerve activity which, in turn, decreases efferent renal sympathetic nerve activity by activation of the renorenal reflexes. Thus, activation of the afferent renal nerves buffers changes in efferent renal sympathetic nerve activity in the overall goal of maintaining sodium balance. In pathological conditions of sodium retention, impairment of the inhibitory renorenal reflexes contributes to an inappropriately increased efferent renal sympathetic nerve activity in the presence of sodium retention. In states of renal disease or injury, there is a shift from inhibitory to excitatory reflexes originating in the kidney. Studies in essential hypertensive patients have shown that renal denervation results in long-term reduction in arterial pressure, suggesting an important role for the efferent and afferent renal nerves in hypertension.

Book Description
This textbook focuses on the vascular biology and physiology that underlie vascular disorders in clinical medicine. Vascular biomedicine is a rapidly growing field as new molecular mechanisms of vascular health and disease are unraveled. Many of the major cardiovascular diseases including coronary artery disease, heart failure, stroke and vascular dementia are diseases of the vasculature. In addition vascular injury underpins conditions like kidney failure and cardiovascular complications of diabetes. This field is truly multidisciplinary involving scientists in many domains such as molecular and vascular biology, cardiovascular physiology and pharmacology and immunology and inflammation. Clinically, specialists across multiple disciplines are involved in the management of patients with vascular disorders, including cardiologists, nephrologists, endocrinologists, neurologists and vascular surgeons. This book covers a wide range of topics and provides an overview of the discipline of vascular biomedicine without aiming at in-depth reviews, but rather offering up-to-date knowledge organized in concise and structured chapters, with key points and pertinent references. The structure of the content provides an integrative and translational approach from basic science (e.g. stem cells) to clinical medicine (e.g. cardiovascular disease). The content of this book is targeted to those who are new in the field of vascular biology and vascular medicine and is ideal for medical students, graduate and postgraduate students, clinical fellows and academic clinicians with an interest in the vascular biology and physiology of cardiovascular disease and related pathologies.
