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.

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).

A sound knowledge of cardiovascular physiology is fundamental to understanding cardiovascular disease, exercise performance and may other aspects of human physiology. Cardiovascular physiology is a major component of all undergraduate courses in physiology, biomedical science and medicine, and this popular introduction to the subject is intended primarily for these students. A key feature of this sixth edition is how state-of-the-art technology is applied to understanding cardiovascular function in health and disease. Thus the text is also well suited to graduate study programmes in medicine and physiological sciences.

An Introduction to Cardiovascular Physiology is designed primarily for students of medicine and physiology. This introductory text is mostly didactic in teaching style and it attempts to show that knowledge of the circulatory system is derived from experimental observations. This book is organized into 15 chapters. The chapters provide a fuller account of microvascular physiology to reflect the explosion of microvascular research and include a discussion of the fundamental function of the cardiovascular system involving the transfer of nutrients from plasma to the tissue. They also cover major advances in cardiovascular physiology including biochemical events underlying Starling's law of the heart, nonadrenergic, non-cholinergic neurotransmission, the discovery of new vasoactive substances produced by endothelium and the novel concepts on the organization of the central nervous control of the circulation. This book is intended to medicine and physiology students.

The essential resource on cardiac hemodynamics—now in a new edition Hemodynamic Rounds, Fourth Edition is intended to help cardiologists, cardiovascular fellowship trainees, residents and other members of the medical community enhance their understanding of cardiac physiology and its associated hemodynamic presentations in health and disease. This includes the basic principles of flow and pressure measurements, systemic as well as coronary hemodynamics in normal and diseased states, and changes in hemodynamics following interventional procedures ranging from TAVI and valvuloplasty to stent placement. Like its popular predecessors, this new edition draws on case studies to illustrate characteristic cardiac hemodynamic findings and discusses the essential methods used in interpreting pressure waveforms as a diagnostic and monitoring tool. The text is organized into chapters on specific areas of the heart, common cardiac pathophysiologic conditions, and hemodynamic situations resulting from different therapeutic procedures. It includes discussions of both normal and abnormal pressure waveforms. This new edition has been revised throughout to include brand new content on aortic and mitral valve stenosis and regurgitation as well as TAVI and mitral clip hemodynamics. Highlights include: Essential and easy to understand resource for those required to interpret cardiac blood flow and blood pressure tracings Covers hemodynamic assessment by cardiac disorder, plus the bedside applications of hemodynamics Revised throughout and includes brand new content on valve stenosis and regurgitation and TAVI and mitral clip hemodynamics Hemodynamic Rounds: Interpretation of Cardiac Pathophysiology from Pressure Waveform Analysis, Fourth Edition is an indispensable tool for all physicians, nurses, and students responsible for measuring and interpreting cardiac waveforms in cardiac diagnosis and monitoring.

This text reviews the postoperative management of patients who have undergone cardiac surgical procedures, some of the most common and most complicated forms of surgery. These patients and their management are characterized by complex challenges, while among the factors determining ultimate clinical outcome, postoperative critical care is of major importance. This new and extensively updated edition of Postoperative Critical Care for Cardiac Surgical Patients maintains the general clinical approach in explaining and analyzing the course of clinical care in patients undergoing cardiac surgery, providing the reader with a practical "cookbook" of postoperative intensive care in adult cardiac patients. It has been extensively updated to include the developments in this field during the last few years, from new chapters on postoperative management of renal, gastrointestinal and respiratory systems, postoperative management of infectious and inflammatory complications, and postoperative care of transplant patients and postoperative safety. This book is of critical importance for cardiac surgeons, cardiac anesthesiologists and intensivists, and defines optimal daily practice for adult patients undergoing cardiac surgical procedures.

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.
