This book was released on 2012-12-06 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relationship between angiotensin II and hypertension was established in 1898 when angiotensin II was shown to modulate systemic blood pressure. Over the intervening decades, a complete characterization of the renin-angiotensin system (RAS) has been achieved, and our understanding of its biochemistry and physiology has led to the directed development of agents such ·as ACE inhibitors and receptor antagonists capable of controlling hypertension. More recently, it was shown that angiotensin II is secreted within certain tissues and that these tissue-specific systems operate independently of the systemic RAS. The novel concept that angiotensin II regulates a number of cardiovascular processes that are unrelated to blood pressure has renewed the interest of both basic and clinical scientists in angiotensin II. The association between angiotensin II and cardiac growth, in particular, has indicated that therapies currently in use for hypertension may have direct application to the treatment of heart failure. The Manitoba Cardiovascular Forum on Angiotensin Receptor Blockade in Winnipeg was convened October 18-20, 1996 to examine the clinical and basic aspects of angiotensin receptor biology as they apply to hypertension and heart failure. In addition, the potential treatment of these conditions using specific angio tensin receptor antagonists was addressed within the context of their immediate therapeutic application and future potential.

Book excerpt: Caffeine in Food and Dietary Supplements is the summary of a workshop convened by the Institute of Medicine in August 2013 to review the available science on safe levels of caffeine consumption in foods, beverages, and dietary supplements and to identify data gaps. Scientists with expertise in food safety, nutrition, pharmacology, psychology, toxicology, and related disciplines; medical professionals with pediatric and adult patient experience in cardiology, neurology, and psychiatry; public health professionals; food industry representatives; regulatory experts; and consumer advocates discussed the safety of caffeine in food and dietary supplements, including, but not limited to, caffeinated beverage products, and identified data gaps. Caffeine, a central nervous stimulant, is arguably the most frequently ingested pharmacologically active substance in the world. Occurring naturally in more than 60 plants, including coffee beans, tea leaves, cola nuts and cocoa pods, caffeine has been part of innumerable cultures for centuries. But the caffeine-in-food landscape is changing. There are an array of new caffeine-containing energy products, from waffles to sunflower seeds, jelly beans to syrup, even bottled water, entering the marketplace. Years of scientific research have shown that moderate consumption by healthy adults of products containing naturally-occurring caffeine is not associated with adverse health effects. The changing caffeine landscape raises concerns about safety and whether any of these new products might be targeting populations not normally associated with caffeine consumption, namely children and adolescents, and whether caffeine poses a greater health risk to those populations than it does for healthy adults. This report delineates vulnerable populations who may be at risk from caffeine exposure; describes caffeine exposure and risk of cardiovascular and other health effects on vulnerable populations, including additive effects with other ingredients and effects related to pre-existing conditions; explores safe caffeine exposure levels for general and vulnerable populations; and identifies data gaps on caffeine stimulant effects.

Download or read book From Hypertension to Heart Failure written by Michael Böhm and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arterial hypertension, coronary heart disease and heart fail ure are the commonest cardiovascular conditions to present in clinical practice. Over the past few years it has become in creasingly clear that they are closely and causally interrelated and that their relationship can have a significant bearing on prognosis. Epidemiological studies have shown that arterial hypertension is one of the most important risk factors for de veloping heart failure. Only one in four patients with hyper tension is adequately managed, and in 50% of cases, the hypertension has not been recognised or treated. Patients with pre-existing hypertension who go on to suffer an acute myocardial infarction have usually not previously had typi cal angina symptoms, the infarct territory is larger, life threatening arrhythmias are commoner and hence in-hospi tal mortality and long-term prognosis are markedly worse. The presence of raised blood pressure in the post-infarct phase doubles the risk of manifest heart failure. The close relationship between hypertension, coronary heart disease and heart failure makes the choice of therapeu tic strategy particularly important. Agents and classes of agents that have prognostic value in all three conditions should be considered first, as synergy might result in addi tional benefits. In such patients, this sort of therapeutic deci sion-making might have further advantages. The use of these agents may prevent complications which are not yet clinically obvious (such as heart failure).

This book was released on 2012-12-06 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: G. HASENFUSS, E. MARBAN Heart failure embodies the central irony of modern medicine. As we have become increasingly adept at treating the major proximate causes of death in Western society, we have effectively converted acute illness into chronic malady. The last twenty years have witnessed a revolution in the treatment of acute coronary syndromes, myocardial infarction in particular. Patients who reach the hospital now have every expectation of leaving alive, but not necessarily well. Our ability to blunt the edge of ischemic insults has en gendered new problems: a new cohort of patients whose hearts function well enough to enable short-term survival, but at the cost of decreased ex ercise tolerance, dyspnea and increased long-term mortality. The irony is compounded by our increasingly sophisticated pharmacopeia for the treat ment of heart failure, which, by slowing the progression of ventricular dys function, has created a chronic illness. The fact of its chronicity makes heart failure no less deadly. In symptomatic patients, mortality exceeds 5-10% per year even with the best contemporary therapy. Not all heart failure is ischemic, of course, but the final common phenotype is eerily concordant regardless of the proximate cause. No wonder, then, that heart failure is the leading cause of hospitalization in America and in Western Europe and that the prevalence of the disease continues to rise. Drugs have indeed revolutionized heart failure therapy, ACE inhibitors and beta-adrenergic blockers having the most outstanding records to date.

Download or read book Control of Gene Expression by Catecholamines and the Renin Angiotensin System written by Heinz Rupp and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: The special issue of Molecular and Cellular Biochemistry focuses on `Control of Gene Expression by Catecholamines and the Renin-Angiotensin System' in health and disease. In recent years, great progress has been made in the understanding of catecholamine and angiotensin II modulated gene expression. There is also increasing evidence that catecholamine and angiotensin II induced cellular injury not solely arises from classical pathways but also from a perturbed gene expression. Taking into account that catecholamines and angiotensin II are vital for a balanced gene expression of many cells, the intriguing possibility arises that various disease are initiated or aggravated by such an imbalance. Catecholamine and angiotensin II influences can be in excess arising from, for example, hypercaloric food intake or psychosocial stress. During early progression of heart failure, sympathetic activity and angiotensin II influences also become increased. Due to beta-adrenergic receptor downregulation, depressed catecholamine influences are expected in the final stage of heart failure. An imbalanced influence of catecholamines and angiotensin II on gene expression leads to disordered molecular structures of the cell and an impaired cell function. This focused issue is organized into chapters concentrating on catecholamines, angiotensin II, and the interaction between catecholamines and angiotensin II. Basic biochemical processes are covered in detail and the potential of these pathways for explaining chronic diseases associated with excess catecholamine and angiotensin II influences should become apparent. It is hoped that this focussed issue triggers novel research into the development of drugs that are targeted at diseases characterized by an imbalanced gene expression involving catecholamines and angiotensin II.

Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Advances in Extra corporeal Perfusion Therapies written by Michael S. Firstenberg and published by BoD – Books on Demand. This book was released on 2019-01-10 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extracorporeal membrane oxygenation (ECMO) has evolved into an exciting and valuable tool to assist in the management of patients experiencing cardiogenic shock, severe acute respiratory failure, or often a combination of both. While outcomes remain less than ideal, they continue to improve with team experience, better patient selection, and a growing understanding of the nuances of managing patients who require mechanical circulatory support. Patients requiring ECMO are often extremely sick and have complex problems - initiating therapy before the development of end-organ damage is critical. Without doubt, teamwork, guidelines, and protocols are cornerstone concepts for clinical and program success - all topics that are emphasized in this text. The goals of this text are to further outline topics that help address some of the key challenges providers face when considering and applying extracorporeal support therapies to the evolving spectrum of acutely ill patients.
