This book was released on 2023-01-01 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book on “Renin-Angiotensin System in Cardiovascular Disease” includes 25 chapters, which are organized in three sections, namely (i) modulatory aspects, (ii) pathophysiological aspects, and (iii) pharmacotherapeutic aspects. It includes an updated as well as comprehensive knowledge about molecular and cellular aspects for the role of the renin-angiotensin system (RAS) in the pathophysiology and therapy of cardiovascular diseases such as hypertension, atherosclerosis, ischemic heart disease, and heart failure. This book emphasizes the molecular and cellular mechanisms, signaling transduction pathways involved in the development of different cardiovascular diseases due to the prolonged activation of RAS. Furthermore, biochemical mechanisms are outlined for the inhibition of this system by the blockade of angiotensin converting enzyme as well as angiotensin II type 1 receptors in patients suffering from cardiovascular abnormalities. Since cardiovascular disease is the number one cause of death worldwide, leading to approximately 17.9 million deaths each year, there is a keen interest in understanding the pathogenesis and improving its therapy. In this regard, we can attest that this book provides ample information about essential components of RAS and their role in the development of cardiovascular disease. From the selection of recognized global experts in their area of investigation, this book can be seen to cover diverse cardiovascular aspects and molecular and cellular mechanisms of angiotensin II action for the development of different cardiovascular abnormalities. It is our contention that this book will be most suitable for promoting knowledge in the field of RAS biology and will be of great interest to health professionals involved in both experimental and clinical cardiology as well as academic investigators and cardiovascular scientists, graduate students, and fellows worldwide.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increased attention has been placed on the activation of the renin-angiotensin-aldosterone system (RAAS) and pathogenetic mechanisms in cardiovascular disease. Multiple studies have presented data to suggest that cardiac and arterial stiffness leading to adverse remodeling of both the heart and vasculature leads to the various pathological changes seen in coronary artery disease, heart failure (with preserved and reduced ejection fractions), hypertension and renal disease. Over-activation of the RAAS is felt to contribute to these structural and endocrinological changes through its control of the Na+/K+ balance, fluid volume, and hemodynamic stability. Subsequently, along these lines, multiple large investigations have shown that RAAS blockade contributes to prevention of both cardiovascular and renal disease. We aim to highlight the known role of the activated RAAS and provide an updated description of the mechanisms by which activation of RAAS promotes and leads to the pathogenesis of cardiovascular disease.
Download or read book New Aspects of the Renin Angiotensin System in Cardiovascular and Renal Diseases written by Dulce Elena Casarini and published by Bentham Science Publishers. This book was released on 2016-11-03 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: The renin-angiotensin system (RAS) is a hormonal system that is responsible for regulating plasma sodium ion concentration and arterial blood pressure in the body. The system involves several peptides such as angiotensin I and II as well as angiotensin converting enzyme (ACE) to enable the constriction of arterial blood vessels in the lung. Angiotensin II also stimulates the production of the hormone aldosterone in the kidneys which brings sodium ions into the bloodstream in exchange for potassium ions. Malfunctions of the RAS can lead to hypertension, heart failure, diabetes and renal complications. Thus the biochemical components of this system serve as important targets for therapeutic drugs. This monograph is a compilation of updated reviews on the RAS. The monograph covers describes the components of the system to explaining its physiological and clinical features in the cardiovascular system and the kidneys. This is followed by sections explaining the biochemistry of the RAS system in cardiovascular and renal disease and the pharmacology of relevant therapeutic drugs. Additional information on the effect of exercise states and methods to quantify angiotensins for molecular diagnosis is also presented in the concluding sections. Information in the monograph will be of interest to physiologists and endocrinologists involved in medical studies or clinical practice. Readers will be able to understand the RAS with a holistic frame of reference.

Download or read book Myocardial Implications in Renin Angiotensin Aldosterone Regulated Hypertension written by Rachel Byrum and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hypertension is a prevalent and potentially deadly disease that affects approximately 116 million (47%) adults diagnosed in the U.S. as reported by the CDC in 2017. Understanding mechanisms responsible for high blood pressure, particularly, the Renin-Angiotensin-Aldosterone System (RAAS) may lead to better treatment options and preventative measures. The current study determines the local role of RAAS on heart muscle and evaluates the indirect Ca2+ homeostatic control of cardiac contractility during high blood pressure. The objectives are to study the expression of RAAS-mediated receptors and the membrane-bound Na/K ATPase (NKA) pump as it relates to the membrane-bound Sodium-Calcium exchanger (NCX). We assess the intracellular sarco/endoplasmic reticulum Ca2+-ATPase (SERCA) in the ventricular myocytes for calcium reuptake since NKA in association with NCX and SERCA may play a significant role in ventricular contractility. The results show a significant decrease in the protein expression for G protein-coupled receptor (GPCR), MAS1 proto-oncogene protein (MAS) for angiotensin 1-7 (Ang1-7) peptides in hypertension. Conversely, protein expression for angiotensin receptor type 1 (AT1R) was significantly higher in cardiomyocytes. While AT1R mediates the enhancement of cardiac contractility, MAS receptor mediates the metabolite of angiotensin II, through Ang1-7, and serves as the protective arm of angiotensin peptides. Further, the results show an increase in protein expression of cardiac membrane-bound NKA isoforms ([alpha]1 and [alpha]2) in the hypertensive rodents, believed to have triggered intracellular calcium ([Ca2+] i) increase via NCX system. In addition, there was a diminution in Ca2+ reuptake pump by SERCA in the sarcoplasmic reticulum (SR) of cardiomyocytes in hypertensive rodents. This could explain increased contractility of the cardiomyocytes through excitation-contraction coupling and calcium-induced calcium release (CICR) mechanisms. The study is a groundwork understanding of cardiac dysfunction during hypertension and may lead to a treatment option and/or preventative measures for sustained blood pressure.
Download or read book Response and Adaptation to Hypoxia written by Sukhamay Lahiri and published by Springer. This book was released on 2013-05-27 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: The underlying theme of this book is the biology of oxygen. The 22 chapters cover aspects of molecular, cellular, and integrative physiological functions. A fundamental evolutionary feature of the oxygen-consuming organism is that it developed a oxygen-sensing mechanism as apart of feedback control at the levels of molecules, organelles, organs, and systems. Oxygen sensing is partic ularly expressed in certain specific cells and tissues like peripheral chemore ceptors, erythroprotein-producing cells, and vascular smooth muscle. Apart of the book is focused on the current issues of this basic question of chemosen sing. Mitrochondria as the major site for cellular oxygen consumption is a nat ural candidate for cellular oxygen sensitivity and adaptation. A section deals with this question. A perennial question concerns chronic environment al oxy gen and the organism's response and adaptation to it. This theme runs through several chapters. Because comparative physiology often provides insight into the mechanisms of environment al adaptation, a chapter on respiration of high altitude birds has been incorporated. Obviously this book gives only glimpses of the immense field of oxygen biology. The book grew out of two meetings where these subjects were discussed. These meetings were sponsored by the American Physiological Society and the Federation of American Societies for Experimental Biology. We are grateful to the FASEB Program Committee and APS publication committee for their sup port. We owe much to Ms. Anne Miller for her editorial assistance. S. L. Philadelphia N. S . C. Cleveland R.

Download or read book Thyroid and Heart Failure written by Giorgio Iervasi and published by Springer Science & Business Media. This book was released on 2009-08-29 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both thyroid dysfunction and heart failure show a high prevalence in the adult population. Frequently, in clinical practice, a multidisciplinary approach is useful to optimize the management of patients with these conditions. Although there is no doubt regarding the close link between cardiovascular pathophysiology and thyroid homeostasis, our understanding of this association is far from being exhaustive. Thyroid hormone regulates the expression of cardiac-specific functional contractile and structural proteins and plays a pivotal role in modulating both diastolic and systolic function as well as peripheral vascular resistance. The close relationship between thyroid and heart dysfunction is strongly supported by recent evidence demonstrating that an altered thyroid profile is a negative prognostic predictor in patients with heart failure. The treatment of chronic heart failure, especially in advanced stages of the disease, continues to be an open and challenging field. The potential of novel thyroid hormone therapies that address the molecular biology of thyroid dysfunction and heart failure thus represents an attractive area of multidisciplinary scientific interest. This book is a readable, integrated, and highly up to date presentation of the clinical, pathophysiological, and basic science aspects of thyroid–heart failure interactions. It addresses a complex subject in an approach that targets a large audience of readers.
