This book was released on 2013-03-14 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inotropic stimulation of the myocardium, as well as vasodilation and diuresis as essential principles in the treatment of congestive heart failure have recently met with considerable criticism and reevaluation. It is generally agreed that unloading of the heart, either through vasodilation and/or diuresis, improves the working conditions of the dilated, failing heart. It reduces myocar dial oxygen consumption through reduction of chamber radius and, thereby, wall tension as the major determinants of myocardial oxygen consumption. Inotropic stimulation, quite in contrast, does not conserve oxygen. It rather consumes energy and that may be disadvantageous in situations of compromised oxygen supply and energy metabolism of the working myocardium. However, under conditions of suf ficient oxygen supply and metabolic support inotropic stimulation may bring about in creased pumping and subsequent improvement of myocardial failure. In recent years it could convincingly be demonstrated that vasodilation leads to symp tomatic improvement of congestive heart failure, improvement of exercise tolerance, and it prolongs life - especially in the case of ACE-inhibitors and the combination of hydra lazine with long-acting nitrates. Quite in contrast, equally beneficial effects could not be demonstrated for inotropic agents in congestive heart failure. Only for the cardiac glyco sides has it been shown that beneficial effects can be achieved, especially if atrial fibril lation with absolute arrhythmia is present. The influence of the cardiac glycosides on the latter represents an effect which is independent of the inotropic action.

Download or read book Cardiac Energetics written by R. Jacob and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Assessment of cardiac energetics at the level of ATP-synthesis, chemomechanical energy transformation and whole organ dynamics as a function of haemodynamic load, ventricular configuration and oxygen- and substrates supply is basic to understanding cardiac function under physiological and pathophysiological (hypertrophy, hypoxia, ischaemia and heart failure) conditions. Moreover, cardiac energetics should be an important consideration in the choice and application of drugs especially in the case of vasodilators, inotropic agents and in cardioprotective measures. Only by considering energetics at the subcellular, cellular, and whole-heart level we can arrive at a better understanding of cardiac performance and ultimately better clinical judgement and drug therapy. Quantification of myocardial energetics will also help to determine the optimal time for surgical interventions such as valvular replacement or aneurysm resection. The present volume is the outcome of an international symposium on cardiac energetics held in Gargellen/Montafon (Austria), June 1986. The contributions will certainly help bridge the existing gap between basic research involving isolated structures and that involving the whole organ, on the one hand, and render the results derived from basic research applicable to clinical problems, on the other hand.

Download or read book Mechanics and Energetics of the Myocardium written by Christian J.F. Holubarsch and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: During several decades of this century, the classical physiological studies on the cardiovascular system have greatly improved our knowledge on the function of this system under normal and pathological conditions. This knowledge was the basis of the breakthrough for diagnostic techniques like the Swan-Ganz catheter, coronary arteriography, left and right heart biopsies, and invasive measurements of contractility, as well as therapeutic tools including aortocoronary bypass surgery, percutanous transluminal coronary angioplasty, and a broad field of pharmacological interventions for the whole spectrum of cardiovascular diseases, especially chronic heart failure. It was during the last decade that the scientific world focused on the evolution of molecular biology of the cardiovascular system so that cardiovascular physiology seemed to become less important. Regarding the myocardium, molecular alterations of important functional proteins (phenotype changes), as well as signal transduction pathways of contractility and cardiac growth have been elucidated. The functional importance of a number of genes has undoubtedly been proven with the help of transgenic animals. Mechanics and Energetics of the Myocardium provides an overview for those researchers and practioners interested in the broad field of molecular biology and physiology of the cardiovascular system.
Download or read book New Concepts in Viral Heart Disease written by H.P. Schultheiß and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent rapid advances in our knowledge of immunological and virological mechanisms involved in the pathogenesis of viral heart disease makes it difficult for everybody working in this field to keep up with the latest developments. How ever, much of what we know is still circumstantial and only vaguely substained. Interdisciplinary understanding and cooperation thus seems necessary to get a better insight into the mechanisms by which viruses may initiate immunological organ-specific tissue injury and disease! This volume evolved out of an international symposium by the same title held on May 25. -28. , 1988 in Tegernsee, near Munich, of which a wide spectrum ofim munological, virological, diagnostical and clinical problems was covered. Both review articles and new experimental and clinical data are included in this volume to give the reader an up-to-date information about current concepts and future aspects. Chapter I serves as an excellent introduction to the epidemiology and natural history of dilated cardiomyopathy / viral heart disease. Although a definite viral etiology in myocarditis and dilated cardiomyopathy is often difficult to establish, epidemiological and serological data incriminate a viral etiology underlying many cases of "dilated cardiomyopathy". Chapters II and III describe the current think ing on virological and immunological mechanisms involved in the pathogenesis of viral heart disease. Among others virus topism, virus persistance, possible mecha nisms and genetic basis of post-infection autoimmunity, and the virus-interaction with the immune system are discussed.

Download or read book Alterations of Excitation Contraction Coupling in the Failing Human Heart written by Gerd Hasenfuss and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alteration of excitation-contraction coupling in the failing human heart was deemed an interesting subject for a dialogue between basic scientists and clinical researchers in continuation of previous Gargellen Conferences concerned with the function of the normal and failing human myocardium. In 1987 basic mechanisms and clinical implications of then new insights into cardiac energetics was followed by a comprehensive review of inotropic stimulation and myocardial energetics in 1989. Here, we undertook a re-evaluation of the principles of inotropic stimulation and of its potential therapeutic value, based on new observa tions from experiments with human myocardium. In 1992 the risk due to myocardial phenotype change as a consequence of adaptation in heart failure was published. Here, alterations of subcellular structures and functions as a consequence of chronic heart failure, summarized as phenotype change, could be described as an essential characteristic of the failing human myocardium. This topic was discussed in greater depth in the volume "Cellular and Molecular Alterations in the Failing Human Heart", considering both the sarcolemma and the phosphodiesterases, as well as excitation-contraction coupling and contractile proteins, extracellular matrix, and mitrochondrial function.
