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 Cardiac Energy Metabolism in Health and Disease written by Gary D. Lopaschuk and published by Springer. This book was released on 2014-08-22 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: The heart has a very high energy demand but very little energy reserves. In order to sustain contractile function, the heart has to continually produce a large amount of ATP. The heart utilizes free fatty acids mainly and carbohydrates to some extent as substrates for making energy and any change in this energy supply can seriously compromise cardiac function. It has emerged that alterations in cardiac energy metabolism are a major contributor to the development of a number of different forms of heart disease. It is also now known that optimizing energy metabolism in the heart is a viable and important approach to treating various forms of heart disease. Cardiac Energy Metabolism in Health and Disease describes the research advances that have been made in understanding what controls cardiac energy metabolism at molecular, transcriptional and physiological levels. It also describes how alterations in energy metabolism contribute to the development of heart dysfunction and how optimization of energy metabolism can be used to treat heart disease. The topics covered include a discussion of the effects of myocardial ischemia, diabetes, obesity, hypertrophy, heart failure, and genetic disorders of mitochondrial oxidative metabolism on cardiac energetics. The treatment of heart disease by optimizing energy metabolism is also discussed, which includes increasing overall energy production as well as increasing the efficiency of energy production and switching energy substrate preference of the heart. This book will be a valuable source of information to graduate students, postdoctoral fellows, and investigators in the field of experimental cardiology as well as biochemists, physiologists, pharmacologists, cardiologists, cardiovascular surgeons and other health professionals.

Download or read book Heart Perfusion Energetics and Ischemia written by Leopold Dintenfass and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 697 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal purpose of a NATO (North Atlantic Treaty Organization) Advanced Research Workshop, a part of the NATO Advanced Study Institutes Programme, is to: (a) exchange thoughts at the frontiers of knowledge or at the frontiers of two (or more) fields or sectors; (b) review and assess the state of the art; (c) formulate recommendations for future research directions; (d) formulate plans for large international scientific experiments. The aim of the ARW on "Microvascular, rheological, metabolic and heat-transfer aspects of the heart: relation to ischaemia and thrombosis", convened in Chateau de Bonas, July 4-11, 1982, was to describe functions and performance of the heart in an interdisciplin ary effort, involving cardiologists, pathologists, biochemists, haemorheologists, physiologists, pharmacologists and bioengineers; to explore interactions between such subfields as blood rheology, micro circulation and ischaemia of the myocardium, heat transfer, heat work and performance as a pump, effect of -metabolites and ion transfer, mechanism of sudden death, protein synthesis and protein molecular transformations. One of the purposes of the Convenor was to relate clinical haemorheology to the heart energetics and heart metabolism. This was only partly established, as difficulties of communications between different fields, difficulties of semantics and of specialized out looks could not be overcome within a -few days. Nevertheless, a gate was opened for communications interchange in the future. There was even a problem within each specialty, and as is rather common, quite diverse views have been expressed. This, of course, is quite normal in the progress of science.

Download or read book Inotropic Stimulation and Myocardial Energetics written by H. Just and published by Springer Science & Business Media. 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 Simulation and Imaging of the Cardiac System written by S. Sideman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ultrasound velocity tomography allows measurement of cardiac geometries for various phases in the cardiac cycle. The present tomograph makes reconstruc tions at intervals of 20 ms. Because of a lack of clear (intramural) landmarks (except the roots of the papillairy muscle), it is difficult to pinpoint spatial trajectories of particular points in the heart. Therefore, a second method was developed of injecting radiopaque markers in the heart and following their motion patterns during the cardiac cycle with help of a biplane X-ray equipment. The data obtained with both methods can be implemented in our finite element model of the heart to compute intramural stresses and strains. The results obtained sofar with the extended Darcy equation to account for the interaction of blood rheology and tissue mechanics look promising. Further testing with more sophisticated subjects than mentioned in Figure 9 is required before it will be implemented in our finite element model of the heart. We conclude that analysis of regional cardiac function, including regional myocardial blood flow, requires still a major research effort but the results obtained sofar justify, to our opinion, a continuation in this direction. Acknowledgement The authors acknowledge Dr. C. Borst and coworkers for doing the animal experiments and prof. Van Campen and dr. Grootenboer for their participation is some aspects of this work.

Download or read book Integrative Cardiology written by Stephen Devries and published by OUP USA. This book was released on 2011-02-03 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrative Cardiology is an exploration of a new and much-needed perspective in cardiac care: the intelligent synthesis of conventional medicine with alternative approaches not typically part of Western medical curriculum. More than a blending of two approaches, this new perspective in cardiology highlights specific gaps in conventional heart care, and examines how alternative approaches may be ideally suited to address these missed opportunities.Cardiology is an ideal specialty for an integrative approach. Heart disease is largely preventable. The influence of nutrition, physical activity, metabolic factors, and emotional state on heart health is unmistakable, and the wide-angle lens of integrative medicine is an ideal model to address these multi-faceted needs. Most importantly, the focus of this work is directed at prevention. The approaches described in this book emphasize collaboration of the patient and health care provider--both seeking to obtain the best possible outcome taking into account the intangible, but vital, nuances of the patient's culture, beliefs, and preferences.The first section in this book describes the core elements of integrative cardiology, beginning with nutrition. Foundational chapters that follow include exercise, botanicals, aspirin, metabolic cardiology, acupuncture, spirituality, mind/body approaches, and energy medicine. Contributing authors, all of whom have a background in academic medicine, share the approaches they have found most effective in their own practices, referencing their work with the best scientific evidence available.
Download or read book Physiology And Pharmacology of Cardio Respiratory Control written by Albert Dahan and published by Springer Science & Business Media. This book was released on 2011-06-27 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: On 15 November 1997, the first international symposium "Neural and Chemical Control of Breathing: Pharmacological and Clinical Aspects" was held at Leiden University Medical Center on the occasion of the retirement of one of the members of the Control of Breathing Research Group of the Departments of Physiology and Anesthesiology, Dr. Aad Berkenbosch. Among others, Dr. Berkenbosch, played an important role in this research group, which made a large and significant contribution to scientific research on the regulation of breathing. This book presents the proceedings of that meeting together with papers of several authors who have strong bonds with the Leiden Departments of Physiology and Anesthesiology. All studies represent state of the art work on the subject of respiratory control and cardiovascular medicine, with emphasis on the physiological, pharmacological and anesthesiological aspects of both fields. The book is divided in several sections: Oxygen Physiology. Prof. John Severinghaus presents among other things his ideas on oxygen sensing and high altitude related diseases. Prof. Honda gives results from studies in a unique set of subjects without carotid bodies. The findings of Honda's group support the idea that an intact hypoxic drive from the carotid bodies is necessary for the generation of central hypoxic depression. Dr. Hans van Beek discusses the effects of hypoxia and hypercapnia on cardiac contractility in animal models. Prof. Oeseburg demonstrates the feasibility of Near Infra Red Oximetry for monitoring tissue oxygenation in patients. Central Chemoreception.
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.
