Over the past years, the thrust of research in cardiology has been toward an understanding of the engineering of the heart as a pump that transports blood to the various organs of the body. More recently, the fields of biochemistry and biophysics have come to influence heart research. The modern cardiologist can no longer pretend to understand, for example, what is happening to the patient with myocardial infarction or ischemia without understanding the principles of molecular biology. The structure and function of the heart are therefore central themes of cardiological research and practice, which incorporate knowledge and discoveries from diverse disciplines. The importance of lipid metabolism in the myocardium has become clearly understood. In the well-oxygenated heart, fatty acids are the preferred substrates. The fact that the heart derives most of its energy from the oxidation of lipids, which represent the larg est energy store of the body, is logical for an organ that must work throughout our lifetime. There are, however, several lines of evidence that during ischemia, lipids may. be harmful to the heart. High levels of free fatty acids in the serum have been suggested to play a role in causing life-threatening arryhthmias and damage in the ischemic heart. The molecular basis for these effects remains poorly understood, and several possible mechanisms for these harm ful effects have been suggested.

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.

Ischaemia-Reperfusion Injury is concerned with the consequences of interrupting and restoring blood flow to tissues. Many common clinical conditions are caused by interruption of blood flow to tissues (eg, ischaemic heart disease, peripheral vascular disease, stroke); blood flow is also interrupted deliberately in many surgical procedures (eg, cardiac surgery, arterial surgery, transplant surgery, limb surgery with tourniquet). In treating such conditions or after performing such operations the aim of the clinician is to restore the blood supply to the ischaemic tissue. Paradoxically, restoration of blood flow to ischaemic tissues can lead to further tissue damage with the potential for severe local and systemic injury. This book focuses on the clinical, pathological and biochemical processes involved in ischaemia-reperfusion injury and gives an overview of the strategies that may be adopted to mitigate or prevent such injury. This book will be of interest to both clinicians and scientists who have to deal with or have interest in this difficult but important problem.

During recent decades, bewildering progress has occurred in the field of Molecular and Cellular Biochemistry. Progress has been extraordinarily rapid primarily because of the challenge for finding solutions to a wide variety of diseases and the availability of new techniques for monitoring biochemical processes. This has resulted in a voluminous and complex literature in the field of biochemical medicine so that there is a clear need for the synthesis and analysis of the continuing expansion of valuable data. It was thus considered appropriate to initiate a new series of monographs, each dedicated to a specialized area of investigation, encompassing molecular and cellular processes in health and disease. Most of the biochemical scientists have devoted their energies in understanding the fundamentals of biochemistry and indeed impressive advances have been made in the past. However, the full potential for explanation has been hampered by the concept of universality of biochemical reactions occurring in the cell. In view of the fact that each organ in the body performs a distinct function, it is now beginning to be realized that each cell type is unique in its need to survive and perform its specific function. Accordingly, the aspect of individualty is receiving increased attention for revealing new avenues in the study of pathophysiology of cellular abnormalities.

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.

Lipid peroxidation is an important cellular process which can lead to detrimental effects if it is not regulated efficiently. Lipid hydroperoxide is formed in an initial step of lipid peroxidation. Lipid hydroperoxide is also known as a potential source of singlet oxygen. Harmful aldehydes are formed when the lipid hydroperoxide is degraded. The formed aldehyde has high reactivity against thiol or amine moieties. Therefore, it could act as a signaling molecule, which might induce the changing of gears inside a cell. Recent studies have shown that lipid hydroperoxide or a slightly modified product of the lipid hydroperoxide reacts with biomolecules such as proteins and aminophospholipids, which leads to formation of amide-type adducts. Amide-type adducts could be one of markers for oxidative stress and could also be an important player in some diseases. In this book, the chemistry and biochemistry of lipid hydroperoxide along with their conjugates with biomolecules are described.

Over the past three decades, impressive progress in the field of pathogenesis, prevention and therapy of ischemic heart disease has resulted in a marked decline in mortality in the Western World. However, the incidence of this devastating disease is on the rise in developing countries. The Ischemic Heart is based upon a recent symposium in Tokyo on the subject. This volume is organized into two sections: (i) Pathophysiologic Mechanisms of Ischemia-Reperfusion Injury and (ii) Preconditioning and Protection of Ischemia-Reperfusion Injury, and contains up-to-date information concerning the current concepts of ischemia-reperfusion injury, the sequence of events resulting in the loss of contractile dysfunction, and mechanisms of cardioprotection by several drugs as well as the role of ischemic preconditioning in attenuating problems associated with ischemia-reperfusion injury.

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.

Cardiac Ischemia: From Injury to Protection has been divided into six parts. The first part describes the differences between hypoxia and ischemia, animal models, the effects of ischemia on myocardial function and metabolism, and the electrophysiological consequences of ischemia. The second part deals with the mechanisms of cardiomyocyte death in ischemia, structural aspects of irreversible ischemic injury, necrosis and apoptosis of cardiac cells, the role of calcium, and the concept of calcium antagonism. The third chapter is a brief description of reperfusion injury, its clinical relevance, and possible prevention. The fourth part summarizes changes in myocardial vasculature during ischemia and reperfusion. The fifth part is the survey of two main possibilities for increasing cardiac resistance to ischemia and hypoxia, i.e. long-lasting adaptation to chronic hypoxia and short-lasting preconditioning. The last part of the book deals with comparative and ontogenetic aspects of cardiac sensitivity to oxygen deprivation; this chapter also summarizes the ontogenetic differences and limitations in endogenous and exogenous protection of the ischemic/hypoxic heart.
