Heart Physiology and Pathophysiology, 4E, provides the foundation for the scientific understanding of heart function and dysfunction, and bridges the gap between basic cardiovascular science and clinical cardiology. This comprehensive text covers all the important aspects of the heart and vascular system. The most important and relevant disorders are presented, with emphasis on the mechanisms involved. The first three editions of this book developed a reputation as the leading reference in cardiovascular science for researchers and academic cardiologists. This recent edition has been updated, expanded, and includes a number of new contributors. It has also been remodeled to expand its usage as a text reference for cardiology residents, practicing cardiologists, and graduate students. Key Features * The most comprehensive book available on this topic * Clear, concise, and complete coverage of all important aspects of cardiovascular physiology/pathophysiology * Completely updated version of the foremost reference on cardiovascular science, including new information on pathophysiology and electrophysiology * Useful tool in bridging the gap between basic science, pathophysiology, and clinical cardiology.

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 &endash; 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.
