Channelopathies In Heart Disease

This book provides an expert overview on ion channel-related arrhythmia mechanisms, and describes important advances in our understanding of how ion channel dysfunction causes cardiac disease. Both, scientific findings and clinical implications are presented and discussed by scientists who have considerably contributed to the field. The book is organized in three parts: part I treats the molecular and electrophysiological mechanisms of function and dysfunction of ion channels, part II focuses on genetics and clinical findings, whereas part III describes novel research techniques, the use of stem cells and animal models and provides an outlook on future investigations and applications. The book is written for scientists in Cardiovascular Biology and Neuroscience and will be of general interest to Medical Doctors in Cardiology, Cardiac Electrophysiology and related disciplines.

Ion channel dysfunction in humans leads to impairment of the excitable processes necessary for the normal function of several tissues, such as muscle and brain. It follows that an increasing number of human diseases have been associated with malfunctioning ion channels, many of which have a genetic component. This volume of Advances in Genetics presents a broad and comprehensive overview of the inherited channelopathies in humans, including clinical, genetic and molecular aspects of these conditions. Keeping true to the scope of the serial, novel genomic and modeling research approaches and a review of potential therapeutic approaches for each of these conditions are also incorporated.

This book delineates the state of the art of the diagnosis and treatment of J wave syndromes, as well as where future research needs to be directed. It covers basic science, translational and clinical aspects of these syndromes. The authors are leading experts in their respective fields, who have contributed prominently to the literature concerning these topics. J wave syndromes are one of the hottest topics in cardiology today. Cardiac arrhythmias associated with Brugada syndrome (BrS) or an early repolarization (ER) pattern in the inferior or infero-lateral ECG leads are thought to be mechanistically linked to accentuation of transient outward current (Ito)-mediated J waves. Although BrS and ER syndrome (ERS) differ with respect to magnitude and lead location of abnormal J waves, they are thought to represent a continuous spectrum of phenotypic expression termed J wave syndromes. ERS is divided into three subtypes with the most severe, Type 3, displaying an ER pattern globally in the inferior, lateral and right precordial leads. BrS has been linked to mutations in 19 different genes, whereas ERS has been associated with mutations in 7 different genes. There is a great deal of confusion as to how to properly diagnose and treat the J wave syndromes as well as confusion about the underlying mechanisms. The demonstration of successful epicardial ablation of BrS has provided new therapeutic options for the management of this syndrome for which treatment alternatives are currently very limited, particularly in the case of electrical storms caused by otherwise uncontrollable recurrent VT/VF. An early repolarization pattern is observed in 2-5% of the US population. While it is clear that the vast majority of individuals exhibiting an ER pattern are not at risk for sudden cardiac death, the challenge moving forward is to identify those individuals who truly are at risk and to design safe and effective treatments.

This book describes human hereditary ion channel diseases of voltage- and ligand-gated ion channels covering the diverse fields of medicine myology, neurology, cardiology, and nephrology requiring a wide and interdisciplinary readership. Interesting parallels in pathogenetic mechanisms of disease are especially emphasized to interest even highly specialized readers in entities outside of their fields. Each author has written an objective overview of his or her particular subject in a way that should allow the reader within a short period of time to obtain a comprehensive picture of the present state of art.

This textbook provides a comprehensive, yet practically orientated overview of classic and novel sports cardiology topics, based on current evidence, guidelines, recommendations and expert experience. Numerous publications have provided guidance to these issues, but it has become increasingly difficult for both students and doctors to obtain a thorough, but practicable overview for optimal clinical care of athletes and patients. This book is intended as an educational work, filling the large gaps that are still present in the current educational guidelines for medical students and cardiology trainees. Textbook of Sports and Exercise Cardiology differs from other sports cardiology books by focusing on clear, practical recommendations based on the latest evidence, primarily targeting those who seek professional background information and education that can easily be transferred into everyday care.

Clearly presents the pathology of heart disease from fetus to adolescence, integrating histology and macroscopy with effects of treatment.
