Biochemistry Of Cardiovascular Dysfunction In Obesity

Obesity is an independent risk factor for cardiovascular disease (CVD) in adults as well as in obese children. This book will provide a description of the impact of obesity on the cardiovascular system and increased predisposition to CVD. It will identify the major biochemical mechanisms that lead to the occurrence of myocardial abnormalities and vascular alterations in obesity. We will also have some discussion on the biochemistry of the so-called obesity paradox in relation to CVD. The contributors to this book are international experts on obesity and associated cardiovascular complications. This book is also uniquely positioned as it focuses on the biochemistry of obesity-induced cardiovascular dysfunction. There are 20 chapters in 2 different parts in this book, comprising of Part A: Pathophysiology of Cardiovascular Complications in Obesity (11 chapters) and Part B: Modification of Cardiovascular Dysfunction in obesity (9 chapters). The intent of this volume is to provide current and basic understanding of the biochemical mechanisms of obesity induced cardiovascular dysfunction that will be of value not only to cardiologists and other allied health professionals, but will also stimulate and motivate biomedical researchers and scientists to find the way to prevent the epidemic of obesity associated cardiovascular abnormalities. Furthermore, this book will serve as a highly useful resource for medical students, fellows, residents and graduate students with an interest in the cardiovascular system. In summary, this book covers a broad range of biochemical mechanisms of obesity-induced cardiovascular complications. We hope that the reader will understand that obesity is linked to an increase in the risk and occurrence of fatal CVD. Furthermore, the underlying message presented in the book is that the cause of obesity related disorders is complex and that understanding the biochemistry of cardiovascular dysfunction may contribute to the development of novel interventions for the prevention and treatment of obesity associated comorbidities.

Global health has been challenged with the dawning of the era of the obesity epidemic, and thus as a consequence, strategies to reduce obesity have become public health priorities. According to the United Nations, obesity has been identified as a concern for achieving Sustainable Development Goals. Obesity is a serious health problem with an increased risk of several common diseases including diabetes, cardiovascular disease, and cancer. Although the fundamental cause of obesity and overweight is an imbalance between calorie intake and calorie expenditure, the underlying biochemical and metabolic processes that cause obesity are not fully understood. Two earlier volumes dedicated to the subject of obesity, published in the series “Advances in Biochemistry in Health and Disease” focused on the pathophysiology of obesity-induced health complications and the biochemistry of cardiovascular dysfunction in obesity. This book brings together contributions from international experts in the field to describe advancements on the mechanisms leading to development of obesity and related complications. There are 21 chapters in two different parts in this book, comprising of Part I: Pathophysiologic Mechanisms of Obesity (11 chapters) and Part II: Therapeutic Mechanisms of Obesity (10 chapters). This book will serve as a resource and be of interest to health professionals, medical students, fellows, residents and graduate students. It will also evoke innovative research and effective approaches for the prevention of obesity. This volume will accentuate that obesity is a major health hazard in its own right and that appropriate public health measures should be implemented to prevent or reduce or even reverse the impact of this global chronic disease.

Cardiovascular and metabolic diseases remain the number one cause of death in developed countries and their prevalence is increasing rapidly in developing nations. This book brings together the recent information on these disorders and the links that exist between them in order to provide a complete picture of drug discovery for these conditions. The main three sections comprehensively discuss obesity, hypertension and cardiovascular disease, and diabetes in turn, following an introduction to the molecular links between them. The final chapter provides perspectives on future directions of the field. Chapters are contributed by leaders in the field from academia and industry and cover biomarkers, risk factors, gene-environment interactions, therapies and the various types of animal models that have been used to study each disease. Case studies describing the implementation of animal models in drug development further enhance the book’s usefulness as a comprehensive guide to this important therapeutic area. Providing a full picture of the various types of animal models that have been used to study obesity, hypertension, and insulin resistance with recent case studies, this book provides a valuable resource for medicinal chemists and clinicians working in these disease areas.

The heart has a very high energy demand but very little energy reserves. In order to sustain contractile function, the heart has to continually produce a large amount of ATP. The heart utilizes free fatty acids mainly and carbohydrates to some extent as substrates for making energy and any change in this energy supply can seriously compromise cardiac function. It has emerged that alterations in cardiac energy metabolism are a major contributor to the development of a number of different forms of heart disease. It is also now known that optimizing energy metabolism in the heart is a viable and important approach to treating various forms of heart disease. Cardiac Energy Metabolism in Health and Disease describes the research advances that have been made in understanding what controls cardiac energy metabolism at molecular, transcriptional and physiological levels. It also describes how alterations in energy metabolism contribute to the development of heart dysfunction and how optimization of energy metabolism can be used to treat heart disease. The topics covered include a discussion of the effects of myocardial ischemia, diabetes, obesity, hypertrophy, heart failure, and genetic disorders of mitochondrial oxidative metabolism on cardiac energetics. The treatment of heart disease by optimizing energy metabolism is also discussed, which includes increasing overall energy production as well as increasing the efficiency of energy production and switching energy substrate preference of the heart. This book will be a valuable source of information to graduate students, postdoctoral fellows, and investigators in the field of experimental cardiology as well as biochemists, physiologists, pharmacologists, cardiologists, cardiovascular surgeons and other health professionals.

Diabetes has long been recognized as a disease of high blood sugar, and there has been a continuous search of the exact reason for its development and effective treatment. In 2005, the World Health Organization had estimated that more than 180 million people worldwide suffer from diabetes mellitus and indicated that this figure is likely to double within the next 20 years. Among the 3.8 million deaths each year associated with diabetes, about two thirds are attributable to cardiovascular complications, and diabetes is now considered to be a major metabolic risk factor for the occurrence of heart disease. Diabetic Cardiomyopathy: Biochemical and Molecular Mechanisms is a compilation of review articles devoted to the study on the topic with respect to biochemical and molecular mechanisms of hyperglycaemia. The wide range of areas covered here is of interest to basic research scientists, clinicians and graduate students, who are devoted to study the pathogenesis of diabetes-induced cardiovascular dysfunction. Furthermore, some chapters are directed towards increasing our understanding of novel ways for the prevention/treatment of cardiomyopathy. Twenty five articles in this book are organized in three sections. The first section discusses general aspects of the metabolic derangements in diabetic cardiomyopathy including metabolic alterations and substrate utilization as well as cardiac remodelling in the heart; role of diet in the development of metabolic syndrome in the heart; effect of hyperglycaemia in terms of biochemical and structural alterations in heart. In the second section, several cellular and molecular mechanisms are discussed indicating that diabetic cardiomyopathy is a multifactorial and complex problem. The third section discusses the prevention and treatment of diabetes using appropriate diet, proper supplements including antioxidants, angiotensin inhibitors and some other drugs. All in all, this book discusses the diverse mechanisms of diabetic cardiomyopathy with some information on new therapeutic approaches for finding solutions to prevent or reverse the development of cardiac dysfunction.

This book summarizes the effects of obesity on health and its correlation with a wide range of debilitating and life-threatening conditions in humans. It discusses the possible pathological mechanisms that are involved in the development of obesity and highlights obesity-associated molecular mechanisms that contribute to reproductive dysfunctions in men and women. The book provides mechanistic insights on the role of obesity in cardiovascular and respiratory disorders, and examines the role of the complementary molecular mechanism of the gut microbiota in the development of obesity. It also reviews the interaction between the metabolic system and immune cells in the pathogenesis of obesity-associated diseases. Lastly, it assesses the latest advances in nanomedicine as an emerging strategy for the treatment of obesity.

Although cardiovascular disease remains the leading proximate cause of death in the United States, it is now estimated that obesity may be equivalent to smoking as the leading cause of preventable death in America. In light of these statistics, this reference presents our current understanding of the epidemiology, pathology, and genetics of the obe

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.
