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.

Heart Metabolism in Failure

Heart Metabolism in Failure

These are exciting times in heart failure research. It is as though many of the pieces of the jigsaw puzzle are available but the puzzle has yet to be assembled.

Heart failure continues to be a major public health problem in the United States with close to half a million new cases diagnosed each year. Moreover, deaths from heart failure are on the increase, in part because of advances in the treatment of other fatal diseases, and in part from the prevalence of lifestyles indifferent to the risk factors for heart disease. This is not to say that no progress has been made in the treatment of heart failure. While for many years treatment was confined to the management of the symptoms, in recent years with the advent of ACE inhibitor and ß blacker therapies, real improvements in cardiac function and life expectancy have been achieved (Volume 4B, Leier). On a more basic level, enormous advances have been made in describing many of the changes in structure and function of the heart and the parallel neurohumoral and circulatory adaptations that occur during the onset of failure. These advances have been made not only by using various animal models of heart failure, but also using fresh failing human heart tissue, which has become readily available for experimental investigation since the advent of cardiac transplantation. Understanding the significance of many of these changes that occur during the transition to failure and the role they play in the etiology of failure is, however, a much more difficult task. These are exciting times in heart failure research. It is as though many of the pieces of the jigsaw puzzle are available but the puzzle has yet to be assembled. The objective of these volumes is to bring together some advances that have been made in recent years in defining one aspect of the failing heart, that is, the role of altered metabolism, in order to facilitate assembly of the puzzle.

Scientific progress with respect to the important role of various lipids in myocardial function and the dearrangements of lipid metabolism underlying ischaemic heart disease(s) has been con siderable in recent years. In 1986 alone, an overall number ofl 044 full papers covering the topics "Lipids-Heart-Heart Disease", have been published in a variety of biochemistry, physiology, pharmacology and cardiology journals (source: Index Medicus). They have broadened our in sight into the molecular basis of myocardial lipidology and the lipido-chemical basis of car diology in health and disease, and have narrowed the gap between promising pharmacological intervention in experimental animals and clinical treatment of patients suffering from an ischaemic heart. Furthermore, they illustrate the fundamental significance of the product of the union between basic and clinical science. The rapid development of knowledge in the "Lipids-Heart-Heart Disease" triad prompted us to organize the International Symposium on Lipid Metabolism in the Normoxic and lschaemic Heart, held in Rotterdam (The Netherlands) on September 22 and 23, 1986. This meeting was a coproject of the Department of Biochemistry I (Medical Faculty, Erasmus University Rotter dam) and the Department of Physiology (Medical Faculty, University of Limburg) and was held under the auspices of the GerritJan Mulder Foundation (named after a famous Rotterdam physi cian and chemist who lived from 1802-1880) whom we thank for their co-operation. The present volume is a compendium of invited papers and contributions selected from the posters presented during the symposium.

A variety of metabolic processes are known to be intimately involved in the maintenance of cellular structure and function. It has also become clear that metabolic events involved in the synthesis and hydrolysis of ATP as well as for the synthesis of proteins and phospholipids are essential for cellular health. The regulation of cell function is generally achieved through participation of a wide variety of hormones and different signal transduction mechanisms for the activation/deactivation of some specific metabolic processes. In this regard cyclic AMP and calcium seem to play a crucial role. Various hormones are also known to affect the genetic machinery of all the cell; however, the exact signals for genetic control of cellular function are not well defined. In particular, the sequence of events concerned with remodelling of different types of cells under various pathological situations is poorly understood. In this book we have therefore dealt with some of these issues from biochemical, molecular biological, physiological, and pharmacological viewpoints. Special emphasis has been laid on understanding heart function and metabolism in health and disease in general, and cardiac hypertrophy, heart failure, and ischemic heart disease in particular. It is hoped that this multidisciplinary information will be of value to basic scientists and clinical investigators.
