Diabetes and cardiovascular disease together account for the largest portion of health care spending compared to all other diseases in Western society. This work seeks to provide an understanding of the causes of diabetes and its cardiovascular complications. As this understanding becomes more widely appreciated, it may serve as a foundation for evidence-based care and wider acceptance of sound science. The International Conference on Diabetes and Cardiovascular Disease, held in Winnipeg, in June 1999, was organized to bring together a multi-disciplinary group of researchers dedicated to further knowledge amongst researchers, care givers, and the managers of the health system. The invited speakers submitted their works for publication, which serves as the basis for this book. Major themes include: epidemiology of diabetes mellitus, metabolic risk factors in diabetes and cardiovascular disease, hypertension in diabetes mellitus, cardiac function in diabetes, glycemic control and improved cardiovascular function, diabetes management, and endothelial function in diabetes.

Research at the molecular and the cellular level has greatly enhanced our understanding of the pathogenesis and management of heart disease. Valuable contributions, towards this end, have been made by scientists from different dis ciplines including biochemistry, physiology, pathology, molecular biology and biophysics. We felt that it would be of interest and value to bring together ex perts from diverse specialities to present their work and to discuss the common problems encountered in their endeavours. In accordance, a symposium was organised in February 1988 at the Postgraduate Institute of Medical Education & Research, Chandigarh. It was held during the annual meeting of the Indian section of the International Society for Heart Research. This book is a compila tion of some of the papers presented at the symposium. The symposium was sponsored by the Council on Cardiac Metabolism of the International Society and Federation of Cardiology. A number of Indian or ganisations gave generous financial help. These included the National Academy of Medical Sciences, Indian Council of Medical Research, Council of Scientific and Industrial Research and Department of Science and Technology. Desktop publishing was used to prepare this volume. In doing so we came to appreciate the remarkable qualities, skills and help rendered by Professor Dharam Vir.

This monograph contains 20 selected papers presented at the Symposium on Subcellular Basis of Contractile Failure which was held in Ottawa during May 11-13, 1989 and is designed for the benefit ofthose who were unable to attend this event. It is now increasingly becoming clear that an excessive amount of calcium is intimately involved in the pathogenesis of a wide variety of heart diseases. Accordingly, the investigations concerning the role of calcium chan nels and their regulatory mechanisms in heart function as well as of the intra cellular calcium overload in cardiac dysfunction are presented here. Since sodium is also considered to influence the cardiac contractile force by chang 2 ing the intracellular concentration of calcium through the Na +-Ca+ exchange 2 mechanism in the cell membrane, the role of Na +-Ca+ exchange in heart func tion as well as pathology of contractile failure is discussed. In view of the new ly discovered implications of the oxygen free radicals in cellular injury, papers concerning the role of these radicals in heart disease are included in this book. For the purpose of clarity, different chapters have been organized under three main headings: (I) Role of cations in heart function, (II) Cardiac hypertrophy and cardiomyopathies, and (III) Ischemic heart disease and cardiac failure.

"Heart Function in Health and Disease" has been organized in five sections to provide an outline of a complex problem in a convenient manner. One section of this book is devoted to shedding light on the restructuring and ontogenic changes in the developing heart whereas in the next section some hypertrophic alterations due to chronic hypoxia are described. The third and fourth sections of this book are concerned with the regulation of cardiac channels as well as signal transduction mechanisms and cardiac electric field. The fifth section contains some pathophysiological events during the development of cardiac hypertrophy and heart failure. All of these areas encompass a significant body of new information that should be valuable to those who work in the field of cardiovascular sciences, as well as those who treat people with heart disease.

This work is based on papers selected from poster presentations made at the International Conference on Heart Failure, Winnipeg, May 20-23, 1994. Although the book is a continuous discussion of subcellular mechanisms of heart failure and its treatment, the presentation has been divided into three sections: the opening section on the subcellular basis of heart failure includes discussions of cytokines, signal transduction, metabolism, extracellular matrix, organ level changes and newer approaches to understanding the pathogenesis of heart failure. The second section focuses on the pathophysiological aspects of cardiomyopathies and their treatment. In the final section, medical, surgical and pharmacological approaches to the treatment of heart failure are discussed in clinical and animal laboratory settings.

Whenever the heart is challenged with an increased workload for a prolonged period, it responds by increasing its muscle mass - a phenomenon known as cardiac hypertrophy. Although cardiac hypertrophy is commonly seen under physiological conditions such as development and exercise, a wide variety of pathological situations such as hypertension (pressure overload), valvular defects (volume overload), myocardial infarction (muscle loss) and cardiomyopathy (muscle disease) are also known to result in cardiac hypertrophy. This text compiles state-of-the-art presentations in the area of molecular biology, cellular physiology and signal transduction in cardiac hypertrophy and heart failure to help in the formulation of new concepts and approaches for stimulating research. The book contains two sections: "Mechanisms of Cardiac Hypertrophy", and "Cardiac Failure in the Hypertrophied Heart". It is hoped that both students and scientists, as well as clinical and experimental cardiologists, will find this book useful in understanding the molecular and cellular events underlying the development of cardiac hypertrophy and the transition from cardiac hypertrophy to heart failure.

The last three decades of the 20th century saw impressive progress in the field of pathogenesis, prevention and therapy of ischemic heart disease which 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. This volume is organized into two sections: pathophysiologic mechanisms of ischemia-reperfusion injury; and preconditioning and protection of ischemia-reperfusion injury it contains late-1990s 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.

The relationship between angiotensin II and hypertension was established in 1898 when angiotensin II was shown to modulate systemic blood pressure. Over the intervening decades, a complete characterization of the renin-angiotensin system (RAS) has been achieved, and our understanding of its biochemistry and physiology has led to the directed development of agents such as ACE inhibitors and receptor antagonists capable of controlling hypertension. More recently, it was shown that angiotensin II is secreted within certain tissues, and that these tissue-specific systems operate independently of the systemic RAS. The novel concept that angiotensin II regulates a number of cardiovascular processes that are unrelated to blood pressure has renewed the interest of both basic and clinical scientists in angiotensin II. The association between angiotensin II and cardiac growth, in particular, has indicated that therapies in use for hypertension may have direct application to the treatment of heart failure. This book focuses on developments in the molecular biology, cellular physiology and structure-function relationships of angiotensin II and its receptors.In addition, this volume covers the therapeutic uses for angiotensin receptor antagonists and considers their potential future applications. This volume aims to be a valuable resource for scientists, practising clinicians and students who are attempting to extend their knowledge in the field of hypertension and heart failure, and who are devoted to improving cardiovascular health.

It has been known or suspected for centuries that there is an association between mind and emotions and the occurrence of heart disease apd sudden death. During the past fifty years this relationship has become identified with the concept of Stress, a notion developed and popularized by Hans Selye. In recent years there has been an upward surge of interest in stress by scientists in several disciplines and by the general public. Although, books, journal articles, seminars and media programs devoted to stress now abound, the definition, manifestations, mechanisms, and management of stress remain uncertain and controversial. In an attempt to clarify the situation an International Symposium on Stress and Heart Disease was held in Winnipeg, Canada, June 26-29, 1984, and the proceedings form the basis of this book and its companion volume "Patho genesis of Stress-Induced Heart Disease". Although most species which have ever existed are now extinct through countless millenia, the human species has successfully adapted to changing conditions ("stressors") such as ice ages, predators and parasites, wars, famine and plague, and now it is coping with rapidly changing social, economic and political circumstances. Such adaptation occurs at all levels of life- at the molecular level within the cell, at the level of the whole cell, in the groups of cells as organs, in the entire organism or individual, and in some cases, in the society in which the individual lives.

A recent comprehensive study of stress and human health by the Institute of Medicine/National Academy of Sciences concludes that individuals who experience any of a wide range of stressful events or situations are at increased risk of developing a physical or mental disorder, including heart disease. Since cardiovascular disease continues to be a leading cause of illness and death, and since the etiology and pathogenesis of several of the commonest forms of heart disease are incompletely known, it is of fundamental impor tance to study the potential role of stress in the genesis of heart disease. Accordingly an International Symposium on Stress and Heart Disease was held in Winnipeg, Canada, June 26-29, 1984 and the proceedings form the basis of this book and its companion volume, "Stress and Heart Disease". The connection between stress (the behavioral sciences) and heart disease (the biomedical sciences) occurs in the mechanisms through which the brain affects or controls the endocrine and the autonomic nervous systems. Initially this linkage appeared to be relatively simple, mainly involving catecholamines and corticosteroids, and communication between nerve cells was thought to be electrical. Now knowledge has increased and concepts have change dramatic ally. Major advances have occurred in biochemical, anatomical, physiological, pharmacological, pathological and behavioral aspects of the neuroendocrine system. The over whelming significance of chemical communication in the nli xviii nervous system has become clear.

It is indeed ironical that in the absence of a complete knowledge of Pathophysiology, clinical cardiologists are left with no choice but to do the best they can to help the patient with the armamentarium of drugs at their disposal. But nothing could be further from truth than to treat the diagnosed end point of a disease process without a full understanding of its patho physiology. This point was eloquently made by Dr. Arnold Katz in his Presidential Address (Chapter 1) at the 8th Annual Meeting of the American Section of the International Society for Heart Research held in Winnipeg, Canada, July 8-11, 1986. This volume represents a part of the scientific proceedings of this Meeting. From a reading of this treatise it will become evident that discoveries of newer scientific facts as well as a better understanding of pathophysiology are continuously influencing/ improving our therapeutic approaches in modern medicine. In this book, latest biochemical, physiological and pharmacological findings on different experimental models such as Myocaridal hypertrophy, Hypertension and heart failure, Diabetes, Cardio myopathies and Cardiac function in shock are described by internationally recognised experts. Hopefully information presented here will provide another building block to the edifice of Science of Cardiology which we all are trying to create.

In the course of the last two decades, it has become increasingly evident that the sarcolemmal, sarcoplasmic reticular and mitochondrial membrane systems play an important role in determining the status of heart funotion in health and disease. These organelles have been shown to be intimately involved in the regulation of cation movements during the contraotion-relaxation cycle. Various proteins imbedded in the phospholipid 2+ + - + + bilayers of these membranes control Ca ,Na, Cl ,K and H concentrations within the oytoplasm by indirect or direct means. Cationic channels, Na+, + 2+ 2+ 2+ + 2+ + + K -ATPase, Ca IMg ATPase, Ca pump, Na -Ca exchanger, Na -II exchanger and adenylate cyclase affect myocardial funotion and viability through their role as regulators of specific ion movements. However, proteins are not the only important constituents of the membrane. Any disturbance in the interaction between proteins and phospholipids in the membrane has been suggested to alter the funotion of the organelles, upset ionic homeostasis and precipitate the development of abnormalities in oardiac performance.It is, therefore, orucial to understand the faotors whioh regulate membrane funotion in their totality if we are to oomprehend the nature of heart performanoe in healthy subjects. Similarly, the study of membrane dysfunotion in a wide variety of experimental models of heart disease at various stages of failure is essential if we are to fully understand the pathogenesis of heart dysfunotion and improve its treatment.

The importance of heart and artery disease as a cause of death and disability is difficult to exaggerate: it causes over half of all deaths in the western world and now accounts for one-quarter of deaths in the entire world. This appalling incidence persists in spite of commendable progress in treatment and prevention, particularly in the last two or three decades. Deaths from coronary disease have decreased by a third in the past twenty years and stroke has decreased by a half in the same period. This remarkable improvement, saving thousands of lives per year, has come about due to changes in life style (low fat diet, control of high blood pressure, less smoking and more exercise) and progress in treatment (more effective drugs, coronary care units, pacemakers, and cardiac surgery). Progress in understanding the pathophysiologic and pharn,acologic mechanisms operative in heart disease have been paramount in the development of more rational and more effective therapy. Dramatic and spectacular surgical treatments have fired the public imagination. Bypass surgery is commonplace and results in complete or considerable relief of symptoms in the majority of patients operated upon.

In 1982, as chance would have it again, an opportunity appeared to Jom the Department of Physiology at Kuwait University. P. Braveny spend four years there, teaching, doing some research, recovering former international contacts. Coming back home, he faced the same gloomy, motionless disfavor as before. November 1989 turned P. Bravenfs career upside down. Immediately after the fall ofthe communist regime, he was elected vice-dean and later dean ofthe Faculty of Medicine, promoted full professor in physiology and appointed the head of the Department ofPhysiology. From 1992 to 1998 P. Braveny served as the vice-rector of Masaryk University. His professional career culminated in his presidency of the XIV World Congress of ISHR in Prague. Understandably, in the following years, he become interested (in his tutor's footsteps) in history of physiology and pub- lished two monoghaphs (E. Babak andV Kruta). This CV would be an incomplete one without mentioning his broad interests in natural sciences and in art, particu- larly music and painting. As a tutored amateur he has acquired certain success in the latter. When reviewing P.Bravenfs whole-life work, largely done under adverse cir- cumstances with minimum financial support, his almost two hundred papers, innu- merable essays and four monographs are a commensurate result. In appreciation, he was awarded honorary membership of the Czech Medical Society, Physiological Society and Cardiological Society, Gold Medal of Masaryk University, Ministry of Education Award etc. Bohuslav Ostadal Makoto Nagano Naranjan S.

The importance of the developmental approach for experimental and clinical cardiology is indisputable. Clinical-epidemiological studies have clearly shown that the risk factors of serious cardiovascular diseases, such as atherosclerosis and ischemic heart disease, are already present during the early phases of ontogenetic development. Furthermore, congenital cardiovascular malformations remain the single largest cause of infant mortality from congenital defects in industrial countries. It is therefore not surprising that the interest of theoretical and clinical cardiologists in the developmental approach keeps increasing. Advances in molecular biology accelerated this trend substantially. This book is based on contributions presented at the international symposium The Developing Heart in Prague in May 2000. It should stimulate the curiosity of cardiovascular scientists in gaining insight into the mechanisms of normal and pathological development.

Evidence suggests that the ischemic preconditioning response is a multi-factorial process consisting of an initial early trigger, an intermediate mediator, and an end effector. Each of these steps in is now its own intense area of investigation. The need to render the heart ischemic for a brief period to invoke the preconditioning response is currently the major factor limiting clinical application of this powerful cardioprotective strategy. Research efforts have utilized brief exposures to pharmacological agents, in lieu of a brief preconditioning ischemia, to trigger/mimic the ischemic preconditioning-induced response. The World Heart Congress held in Winnipeg in July 2001 provided a forum for the presentation of insights into the basic mechanisms of ischemia and reperfusion injury, as well as novel strategies to protect the heart from cell death, ventricular arrhythmias, and contractile dysfunction. Many pioneers in the fields of ischemia-reperfusion injury and preconditioning-induced protection presented there and the chapters in this book represent selected papers from these symposia.

The limitation in number of donor hearts led to the establishment of alternative treatments such as left ventricular assist devices (LVAD), which have been used. Although several reports suggest the native ventricular function recovers after long-term LVAD support - a process called "reverse remodelling" - the underlying biological mechanisms are unclarified. Various molecular pathways of the human myocardium associated with apoptosis, response to stress, or matrix changes are known to be altered under conditions of heart failure and some of them have been shown to be reversible regulated during left ventricular mechanical support. This suggests that the "reverse remodelling" is actually, at least in part, a reverse mechanism. One explanation may be, under mechanical circulatory assist, volume and pressure overload is reduced, and thus ventricular wall stress decreases, leading to improved myocardial blood supply. This may be one explanation for the molecular myocardial changes, and may reflect a possible cause of "reverse remodelling".

Molecular Defects in Cardiovascular Disease provides an in-depth discussion of the molecular mechanisms underlying the genesis of cardiovascular defects and the implications this has on current and emerging targeted therapeutics. Divided into three sections, this book covers the scientific foundations of our present understanding as well as the array of clinical manifestations and their treatment. The first section covers Molecular Mechanisms of Heart Disease, with discussion of the development of cardiovascular dysfunction. The remaining two sections provide a more clinical focus. The second, Cardiac Hypertrophy and Heart Failure deals with metabolic derangements, Ca2+ handling, and subcellular remodeling. It illustrates the wide variety of molecular defects which may serve as targets associated with the transition from cardiac hypertrophy to advanced heart failure. The third section, Hypertension and Diabetes, provides molecular rationale for the pathogenesis of hypertension and diabetic cardiomyopathy, as well as highlighting the importance of hormones toward this end. A necessary resource for clinicians and researchers, this book elucidates the experimental basis of the practice of cardiology. It is the culmination of our advances in the understanding of cardiovascular molecular biology and a blueprint for the efficacious use of targeted therapies.

Rapid advances in molecular medicine have led to pronounced new developments in experimental and clinical cardiology. In the embrace of modern molecular biology and bridging the gap between the clinical and the genomic, cardiovascular medicine has seen major strides in the understanding of the molecular mechanisms that drive disease progression. The ability to rapidly identify candidate human genes for cardiovascular diseases lends itself to the development of diverse strategies for disease treatment and management. The wide variety of gene expressions proffers excellent targets for novel therapeutics. Gene therapy is steadily increasing in viability and represents a fascinating arena of research and clinical focus. This book is based on two international Mendel symposia on “Genes and the Heart,” joint meetings of the Japanese and European sections of the International Academy of Cardiovascular Sciences. Highlighting selected symposia contributions, this book explores the role of molecular biology and genetics in the basic knowledge, genesis, and clinical interventions of cardiovascular diseases.
