Sex Differences in Cardiovascular Physiology and Pathophysiology is a comprehensive look into the often overlooked and underappreciated fundamental sex differences between men and women and how those differences affect the cardiovascular system. It covers cardiovascular function, anatomy, cell signaling and the development of pathology. With contributions from world-renowned research investigators, this up-to-date reference compiles critical knowledge on cardiovascular sex differences, providing researchers and clinicians with a better understanding of the diagnosis, prevention and treatment of cardiovascular diseases in both men and women.
Evidence accumulated over the past decade show that gonadal steroid hormones participate in an important way in the physiological and pa thophysiological regulation of the cardiovascular system. The hor monal profile appears to put males at a disadvantage biologically in terms of cardiovascular diseases. The incidence of hypertension is higher in men than in pre-monopausal women indicating an influence of gender on the hypertensive disease process. Males and females have equivalent cholesterol levels until puberty but males suffer an ex ponential increase in heart disease in their forties, while the female rise does not start until a decade later, after menopause. Animal and human studies provided ample evidence, that estrogens lower the levels of low density lipoproteins and keep high density lipoproteins elevated. These changes may be advantageous in the prevention of heart diesease. Co ronary artery atherosclerosis has been shown to be more pronounced in ovarectomized female monkeys as in intact females. Androgen, con versely, lowers the high density lipoproteins and elevates low density lipoproteins. Regarding blood pressure, it is well established that hypertension is more severe or develops more rapidly in male than fe male rats in several genetic forms of hypertension, and that gonadal steroid hormones are probably playing an important role in explaining this observation. Risk factors of human hypertension and coronary heart dies ease include menopause and ovarectomy.
The world is faced with an epidemic of metabolic diseases such as obesity and type 2 diabetes. This is due to changes in dietary habits and the decrease in physical activity. Exercise is usually part of the prescription, the first line of defense, to prevent or treat metabolic disorders. However, we are still learning how and why exercise provides metabolic benefits in human health. This open access volume focuses on the cellular and molecular pathways that link exercise, muscle biology, hormones and metabolism. This will include novel “myokines” that might act as new therapeutic agents in the future.
While menopause in women is a well-established and well documented phenomenon, the andropause in men is a relatively new concept. The terms male menopauseand andropausesuggest that this is an abrupt phenomenon related to a sudden deprivation of sex hormones. Unlike the menopause, which has a relatively sudden onset, the andropause appears to be a gradual process. It has been hypothesized that an androgen deficiency might develop with aging. Androgens and the Aging Male explores this hypothesis. The book focuses on the gradually progressive problems related to the decline in androgens that can occur with advancement of age. It examines the debate about the extent to which an age-dependent decline in androgens leads to health problems that affect or impair the quality of life, and the theory behind it. In addition, it reviews studies evaluating the effects of androgen supplementation. Androgens and the Aging Male comprehensively covers androgen function and how it changes over time.
The book systematically describes the clinical and scientific aspects of cardiovascular calcification. Chapters detail the mechanisms associated with arterial and valve calcification, relevant risk factors, pathophysiology and the latest therapeutic techniques. Recent diagnostic technological developments including how computed tomography (CT) scanning can be utilized along with Agatston score to quantify coronary arterial calcification when investigating whether a patient for sub-clinical atherosclerosis are covered. The correlation with the presence of arterial calcification and extent of coronary stenosis is also explored. Cardiovasular Calcification details relevant aspects of the basic science and reviews the latest pathological and therapeutic techniques used in treating patients with cardiovascular calcification. It is therefore an essential resource for practicing cardiologists, cardiac surgeons, vascular specialists and radiologists.
Sex Differences in Physiology is an all-encompassing reference that details basic science research into sex differences in all physiological fields. It includes scientific discoveries concerning sex differences in cardiovascular, respiratory, renal, gastrointestinal, and musculoskeletal physiology. In addition, coverage of the development, endocrinology, neurophysiology, immunity, and metabolism is included, making this important reference a resource that will meet the needs of investigators interested in incorporating sex differences into their research programs, while also providing clinicians with the basis for providing the best sex-based medical treatment options available. Provides a sweeping, organ-by-organ review of currently observed sex differences in animal models and human disease Explains how sex differences influence physiology and disease Provides the critical knowledge on sex differences for better understanding of prevention and treatment of diseases
This book gathers together contributions from internationally renowned authors in the field of cardiovascular systems and provides crucial insight into the importance of sex- and gender-concepts during the analysis of patient data. This innovative title is the first to offer the elements necessary to consider sex-related properties in both clinical and basic studies regarding the heart and circulation on multiscale levels (i.e. molecular, cellular, electrophysiologically, neuroendocrine, immunoregulatory, organ, allometric, and modeling). Observed differences at (ultra)cellular and organ level are quantified, with focus on clinical relevance and implications for diagnosis and patient management. Since the cardiovascular system is of vital importance for all tissues, Sex-Specific Analysis of Cardiovascular Function is an essential source of information for clinicians, biologists, and biomedical investigators. The wide spectrum of differences described in this book will also act as an eye-opener and serve as a handbook for students, teachers, scientists and practitioners.
For over 50 years, coronary angiography has been the mainstay of diagnosing and quantifying the extent of coronary artery disease. However appreciation of the inherent limitations of conventional angiography has led to a plethora of new imaging modalities, each with their relative strengths and potential pitfalls. Advances in these techniques have given clinicians, as well as researchers, an overwhelming amount of information and the need for thoughtful interpretation. This outstanding book provides a comprehensive overview of the current status of imaging of coronary atherosclerosis. Covering the wide variety of available imaging modalities, the book provides state-of-the-art knowledge from leading authorities in each area. In their discussion, the authors include both invasive and non-invasive modalities, including the gold standard coronary angiography, the growing field of IVUS, and novel techniques such as functional imaging, molecular imaging, and the integration of biomarkers. The key concepts and practical information given in this volume will provide the reader with the necessary understanding to choosing appropriate imaging studies and building confidence in their skill set with each.
It's obvious why only men develop prostate cancer and why only women get ovarian cancer. But it is not obvious why women are more likely to recover language ability after a stroke than men or why women are more apt to develop autoimmune diseases such as lupus. Sex differences in health throughout the lifespan have been documented. Exploring the Biological Contributions to Human Health begins to snap the pieces of the puzzle into place so that this knowledge can be used to improve health for both sexes. From behavior and cognition to metabolism and response to chemicals and infectious organisms, this book explores the health impact of sex (being male or female, according to reproductive organs and chromosomes) and gender (one's sense of self as male or female in society). Exploring the Biological Contributions to Human Health discusses basic biochemical differences in the cells of males and females and health variability between the sexes from conception throughout life. The book identifies key research needs and opportunities and addresses barriers to research. Exploring the Biological Contributions to Human Health will be important to health policy makers, basic, applied, and clinical researchers, educators, providers, and journalists-while being very accessible to interested lay readers.
