Book Synopsis Conversations on Cardiac Physiology by : Mark Noble
Download or read book Conversations on Cardiac Physiology written by Mark Noble and published by Cambridge Scholars Publishing. This book was released on 2023-12-08 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses and corrects widespread misconceptions regarding heart physiology. Such misconceptions include: the voltage in cells is attributed to potassium ion concentration differences between the extracellular and intracellular compartments, which are the same in all organs of the body, whereas the voltage in cells of these same organs vary widely. This book argues that depolarisation and repolarisation can be explained by electron outflow and mitochondrial production, respectively; and that the trigger for internal calcium ion release is calcium ions bound to the inner leaflet of the cell membrane. In the book, Starling’s Law is contrasted with contractility increase, and it is posited that hypertension is not caused by salty diet, coronary artery disease risk is not correlated with total cholesterol (rather, only with some specific cholesterols), and that drug administration should be titrated.

Book Synopsis Excitation-Contraction Coupling and Cardiac Contractile Force by : Donald Bers
Download or read book Excitation-Contraction Coupling and Cardiac Contractile Force written by Donald Bers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: How is the heartbeat generated? What controls the strength of contraction of heart muscle? What are the links between cardiac structure and function? How does our understanding of skeletal and smooth muscle and non-muscle cells influence our thinking about force development in the heart? Are there important species differences in how contraction is regulated in the heart? How do the new molecular data fit together in understanding the heart beat? What goes wrong in ischemia, hypertrophy, and heart failure? This book paints a modern `portrait' of how the heart works and in this picture the author shows a close-up of the structural, biochemical, and physiological links between excitation and contraction. The author takes the reader through a series of important, interrelated topics with great clarity and continuity and also includes many useful illustrations and tables. The book starts by considering the cellular structures involved in excitation-contraction coupling and then described the characteristics of the myofilaments as the end effector of excitation-contraction coupling. A general scheme of calcium regulation is described and the possible sources and sinks of calcium are discussed in simple, but quantitative terms. The cardiac action potential and its many underlying currents are reviewed. Then the characteristics of some key calcium transport systems (calcium channels, sodium/calcium exchange and SR calcium uptake and release) are discussed in detail. This is then built into a more integrated picture of calcium regulation in succeeding chapters by detailed discussions of excitation-calcium coupling mechanisms (in skeletal, cardiac, and smooth muscle), the interplay between calcium regulatory processes, and finally mechanisms of cardiac inotropy, calcium overload, and dysfunction (e.g., ischemia, hypertrophy, and heart failure). Excitation-Contraction Coupling and Cardiac Contractile Force – Second Edition is an invaluable source of information for anyone who is interested in how the heart beat is controlled and especially suited for students of the cardiovascular system at all levels from medical/graduate students through senior investigators in related fields.

Book Synopsis Regulation of Cardiac Contractility by : R. John Solaro
Download or read book Regulation of Cardiac Contractility written by R. John Solaro and published by Biota Publishing. This book was released on 2011-04-01 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contractility describes the relative ability of the heart to eject a stroke volume (SV) at a given prevailing afterload (arterial pressure) and preload (end-diastolic volume; EDV). Various measures of contractility are related to the fraction as the SV/EDV or the ejection fraction, and the dynamics of ejection as determined from maximum pressure rise in the ventricles or arteries or from aortic flow velocities determined by echocardiography. At the cellular level, the ultimate determinant of contractility is the relative tension generation and shortening capability of the molecular motors (myosin cross-bridges) of the sarcomeres as determined by the rates and extent of Ca activation, the turnover kinetics of the cross-bridges, and the relative Ca responsiveness of the sarcomeres. Engagement of the regulatory signaling cascades controlling contractility occurs with occupancy and signal transduction by receptors for neurohumors of the autonomic nervous system as well as growth and stress signaling pathways. Contractility is also determined by the prevailing conditions of pH, temperature, and redox state. Short-term control of contractility is fully expressed during exercise. In long-term responses to stresses on the heart, contractility is modified by cellular remodeling and altered signaling that may compensate for a time but which ultimately may fail, leading to disorders.
Book Synopsis Current Concepts in Cardiovascular Physiology by : Oscar Garfein
Download or read book Current Concepts in Cardiovascular Physiology written by Oscar Garfein and published by Elsevier. This book was released on 2012-12-02 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current Concepts in Cardiovascular Physiology examines seven different areas related to the field of cardiac physiology. In addition to the biochemistry and receptor pharmacology of the heart, this book explores coronary physiology, cardiovascular function, and neural and reflex control of the circulation. The electrophysiology and biophysics of cardiac excitation are also considered, along with humoral control of the circulation. This monograph consists of seven chapters and opens with an overview of the biochemistry of the heart, with emphasis on cardiac energy metabolism and the ways in which metabolism and the biochemical pathways are controlled. The mechanisms whereby physiological events influence biochemical activities and vice versa are also discussed. The following chapters look at the chemistry and physiology of myocardial receptors; the complex interplay between the nervous and cardiovascular systems; and the chemical and hormonal factors that regulate, modify, and modulate the cardiovascular system. The influence of humoral, neural, intrinsic, vascular, and myocardial factors on coronary blood flow is also examined, along with muscle mechanics; the biochemical basis of contraction; cardiac function; and the factors determining the heart's electrophysiologic behavior. This text is directed primarily at clinical cardiologists, cardiovascular surgeons, and trainees in their disciplines, as well as internists, medical students, and house officers.

This book is intended to medicine and physiology students.
Book Synopsis Handbook of Pathology and Pathophysiology of Cardiovascular Disease by : Stephen M. Factor
Download or read book Handbook of Pathology and Pathophysiology of Cardiovascular Disease written by Stephen M. Factor and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autopsy derives from the greek word autopsia, which means act of seeing with one’s own eyes. It remains the most objective and accurate method to understand human. disease. Unfortunately, the volume of autopsies in teaching hospitals has decreased dramatically over the past years. The crucial factors that account for this are the recent progress and development of new technologies, especially in diagnostic imaging, immunology, cell biology and genetics. Additionally, the perpetual fear of legal liability by physicians accounts for its further decline. Consequently, physicians and medical students are engaged in fewer autopsies and are not reaping the rich educational rewards that accompany these examinations. The purpose of the autopsy is not only to establish the cause of death, but also to determine the nature and course of the disease process. Our goal with this book is to emphasize the importance of the post-mortem exam and the correlation between pathologic material and clinical data by analyzing actual cases with problem-based methodology. The focus of this handbook is on cardiovascular disease, and when appropriate, other disease categories are included if they have an impact on cardiovascular function. The approach is more than the usual clinico-pathological correlation. Rather, we attempt to present the material from the perspective of the autopsy table. We use the clinical data as the initial framework and the autopsy findings to develop a true understanding of the disease and the associated pathophysiology of the condition.

Book Synopsis How Tobacco Smoke Causes Disease by :
Download or read book How Tobacco Smoke Causes Disease written by 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.
Book Synopsis Practical Pediatric Cardiology by : Alan G. Magee
Download or read book Practical Pediatric Cardiology written by Alan G. Magee and published by Springer. This book was released on 2015-11-02 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heart disease in children has a number of diagnostic traps for the unwary, and all of us involved in the specialty have been caught at one time or another. For example, it is sometimes very difficult to differentiate between respiratory and cardiac disease in infants and between neurological and cardiac conditions in older children, and the consequences of taking the wrong path can be significant. This book is a collection of cases highlighting situations which can ensnare even the best cardiologist. Although they illustrate the importance of taking a good history and performing a thorough examination, the most important lesson is learning to keep an open mind and develop the ability to think laterally. As clinicians we need to have the confidence to make a decision for our patients but also the humility to be able to acknowledge that we don’t always get it right first time, and it is imperative that we learn from the experience. We hope the reader will find these short chapters interesting and while they are not evidence-based medicine in the true sense, they do represent a wide range of clinical experience from which we can all learn.

Book Synopsis Strategies to Improve Cardiac Arrest Survival by : Institute of Medicine
Download or read book Strategies to Improve Cardiac Arrest Survival written by Institute of Medicine and published by National Academies Press. This book was released on 2015-09-29 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cardiac arrest can strike a seemingly healthy individual of any age, race, ethnicity, or gender at any time in any location, often without warning. Cardiac arrest is the third leading cause of death in the United States, following cancer and heart disease. Four out of five cardiac arrests occur in the home, and more than 90 percent of individuals with cardiac arrest die before reaching the hospital. First and foremost, cardiac arrest treatment is a community issue - local resources and personnel must provide appropriate, high-quality care to save the life of a community member. Time between onset of arrest and provision of care is fundamental, and shortening this time is one of the best ways to reduce the risk of death and disability from cardiac arrest. Specific actions can be implemented now to decrease this time, and recent advances in science could lead to new discoveries in the causes of, and treatments for, cardiac arrest. However, specific barriers must first be addressed. Strategies to Improve Cardiac Arrest Survival examines the complete system of response to cardiac arrest in the United States and identifies opportunities within existing and new treatments, strategies, and research that promise to improve the survival and recovery of patients. The recommendations of Strategies to Improve Cardiac Arrest Survival provide high-priority actions to advance the field as a whole. This report will help citizens, government agencies, and private industry to improve health outcomes from sudden cardiac arrest across the United States.
