Stress, Catecholamines, and Cardiovascular Disease


Book Description

The starting point for understanding the roles of stress and catecholamines in cardiovascular disorders is a theory defining stress. This book presents a new homeostatic theory of stress and distress and uses it to explain how systems using the endogenous catecholamines - norepinephrine, epinephrine, and dopamine - and other effector systems maintain the internal environment during stress. The theory proposes coordinated activation of the body's several stress systems in primitively specific patterns during exposure to various stressors. Comparator homeostats interpret afferent information about specific physiological or chemical variables and regulate operations of the effector systems. Via a hierarchical mosaic of central nerve cell clusters, the brain constantly redefines homeostasis by resetting homeostats, especially during stress.




Encyclopedia of Heart Diseases


Book Description

The Encyclopedia of Heart Diseases is an accurate and reliable source of in-depth information on the diseases that kill more than 12 million individuals worldwide each year. In fact, cardiovascular diseases are more prevalent than the combined incidence of all forms of cancer, diabetes, asthma and leukemia. In one volume, this Encylopedia thoroughly covers these ailments and also includes in-depth analysis of less common and rare heart conditions to round out the volume's scope. Researchers, clinicians, and students alike will all find this resource an invaluable tool for quick reference before approaching the primary literature.* Coverage of more than 200 topics, including: applied pharmacology of current and experimental cardiac drugs, gene therapy, MRI, electron-beam CT, PET scan put in perspective, cardiac tests costs and justification, and new frontiers in cardiovascular research* More than 150 helpful figures and illustrations!* Dr. Khan is a well-published and respected expert in heart and heart diseases




Myocardial Injury


Book Description

The chapters of this book represent contributions by plenary lecturers and invited symposium speakers of the Fourth Annual Meet ing of the American Section of the International Society for Heart Research, held on May 26-29, 1982 in New Orleans, Louisiana. The aim of the Organizing Committee was to present an up-to-date picture of our knowledge of myocardial injury which would be equally useful to basic scientists and clinicians. The papers of this volume are divided into two groups: a) those dealing primarily with techniques to study myocardial injury, and b) those that discuss the different types of myocardial lnJury. The grouping of the papers within each of these headings roughly corresponds to the symposia presented at the meeting. I wish to acknowledge the financial support of the National Institutes of Health. Without grant HL 29149, the program could not have been financed. Contributions from the following companies were also gratefully received: Ayerst Laboratories, Ciba-Geigy, Merck Sharp and Dome, Pfizer Laboratories Division, A.H.

Stress and Cardiovascular Disease


Book Description

The main aim of this book is to evaluate the concept of stress and provide tools for physicians to identify patients who might benefit from stress management. This will incorporate a detailed description of the physiological and pathophysiological consequences of acute and chronic stress that might lead to cardiovascular disease. The book will aim to critically evaluate interventional research (behavioural and other therapies) and provide evidence based recommendations on how to manage stress in the cardiovascular patient. Our intentions are to define and highlight stress as an etiological factor for cardiovascular disease, and to describe an evidence based "tool box" that physicians may use to identify and manage patients in whom stress may be an important contributing factor for their disease and their risk of suffering cardiovascular complications.

Pituitary Adenylate Cyclase-Activating Polypeptide is the twentieth volume published in the Endocrine Updates book series under the Series Editorship of Shlomo Melmed, MD.




How Tobacco Smoke Causes Disease


Book Description

This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.




Magnesium in the Central Nervous System


Book Description

The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.




Catecholamines and Heart Disease


Book Description

A concise, in-depth analysis of the status of the sympathetic system in heart diseases This book summarizes the functional status of the sympathetic neural system in cardiological diseased states and highlights aspects of sympathetic neural activity that are important to an overall understanding of the pathophysiology process. Critical reviews of methods for evaluating sympathetic activity are discussed, existing data is closely scrutinized, and attempts are made to delineate the factors derived from increased sympathetic activity. The book provides a physiologically and clinically based approach to the investigation of the involvement of catecholamines in cardiovascular diseases, which makes it a valuable addition to the reference collections of researchers, clinical scientists, and graduate students.




Stress and Heart Disease


Book Description

It has been known or suspected for centuries that there is an association between mind and emotions and the occurrence of heart disease apd sudden death. During the past fifty years this relationship has become identified with the concept of Stress, a notion developed and popularized by Hans Selye. In recent years there has been an upward surge of interest in stress by scientists in several disciplines and by the general public. Although, books, journal articles, seminars and media programs devoted to stress now abound, the definition, manifestations, mechanisms, and management of stress remain uncertain and controversial. In an attempt to clarify the situation an International Symposium on Stress and Heart Disease was held in Winnipeg, Canada, June 26-29, 1984, and the proceedings form the basis of this book and its companion volume "Patho genesis of Stress-Induced Heart Disease". Although most species which have ever existed are now extinct through countless millenia, the human species has successfully adapted to changing conditions ("stressors") such as ice ages, predators and parasites, wars, famine and plague, and now it is coping with rapidly changing social, economic and political circumstances. Such adaptation occurs at all levels of life- at the molecular level within the cell, at the level of the whole cell, in the groups of cells as organs, in the entire organism or individual, and in some cases, in the society in which the individual lives.




Heart-Brain Interactions


Book Description

In the last decade there has been a growing interest in the study of the interactions between the heart and the brain, especially in the field of cerebral ischemia. The interactions between cardiovascular and cerebrovascular diseases are of relevance not only for research investigation, but also for clinical implications in the daily clinical practice. i.e. A wealth of information has been gathered particularly on three topics, cardiovascular consequences of cerebral injuries, cardioembolic stroke, and association of carotid and coronary artery disease. The available information, however, is still sparse and fragmentary mainly because of the lack of commun ication between neurologists and cardiologists. With the aim of improving communication between several disciplines and technologies, we started to organize since 1987 in Bologna, Italy, an international Symposium on heart brain interactions to be held every 3 years. Our intention was to gather prominent clinicians and researchers from outstanding cardiologic and neuro logic institutions actively involved in the study of heart-brain interactions. The ambitious goal has been to fit different pieces of information like in a puzzle. This book originates from the contributions presented at the 2nd Sympo sium which was held in Bologna on November 30-December 1, 1990. The book is subdivided into three sections: I cardiovascular consequences of cerebral damage, II cardiogenic cerebral ischemia, III cerebrovascular and coronary artery disease.
