Book Description
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.

Book Description
ATP plays a central role in the two leading causes of cardiac morbidity and mortality in the western world: ischemia and heart failure. We are in our infancy applying what is known about biology and chemistry of ATP toward developing effective therapies for these diseases. In this volume, the current understanding of the chemistry and biology of ATP specifically in the cardiomyocyte is presented. New insights into ATP have been gleaned using biophysical techniques allowing dynamic measurement of chemical events in the intact beating heart and using new animal models in which cardiac proteins are either over expressed, deleted or harbor specific mutations. This book provides a summary of the basic understanding and includes illustrations of why ATP and the Heart is important to both the clinician and scientist.

Book Description
Genetic alterations in cancer, in addition to being the fundamental drivers of tumorigenesis, can give rise to a variety of metabolic adaptations that allow cancer cells to survive and proliferate in diverse tumor microenvironments. This metabolic flexibility is different from normal cellular metabolic processes and leads to heterogeneity in cancer metabolism within the same cancer type or even within the same tumor. In this book, we delve into the complexity and diversity of cancer metabolism, and highlight how understanding the heterogeneity of cancer metabolism is fundamental to the development of effective metabolism-based therapeutic strategies. Deciphering how cancer cells utilize various nutrient resources will enable clinicians and researchers to pair specific chemotherapeutic agents with patients who are most likely to respond with positive outcomes, allowing for more cost-effective and personalized cancer therapeutic strategies.

Book Description
Chronic Heart Failure: Pathophysiology, Risk factors, and Mechanisms is the first of two separate but closely related volumes which aim to provide an inclusive overview on Chronic Heart Failure (CHF). This first volume is focused on the epidemiology, classification, molecular mechanisms, pathophysiology, causes, identification and interactions of heart failure. It will explain the uncertainties and issues in Heart Failure by helping readers understand the physiopathology of CHF in the light of behavioural risk factors. 2D and 3D speckle tracking echocardiography have been used to quantify regional alterations of longitudinal strain and area strain, through their polar projection, which allows a further evaluation of both the site and extent of myocardial damage. The analysis of strain can identify subclinical cardiac failure (myocyte remodelling) which is a major issue in CHF. Myocardial Strain, measure by speckle tracking echocardiography, is frequently attenuated in these conditions and can be utilized for the evaluation of disease progression and the effect of therapeutic interventions as well as prevention because it could be a manifestation of behavioural risk factors. These 2 separate volumes serves as essential references to both researchers and practicing clinicians, proposing novel methods of research by using behavioural and environmental risk factors as intervention agent, as well as discussing deficiency in the present approaches in management of HF and proposing new methods of early diagnosis and therapies for the clinical management of CHF. - Includes a number new and controversial topics: Roles of both behavioural and nutritional risk factors in CHF; considering behavioural intervention which may change the remodelling, as well as nutrient supplementation or change of diet in preventing CHF or converting resistant HF in to HF responding to therapy; Evidence-based knowledge on CHF, with an emphasis on viewing CHF as a disease of the brain and contribution from other systems; Pre–Heart failure which can be prevented to restore normal cardiomyocyte function; Pathogenesis of HF in chronic kidney disease; 2D and 3D speckle tracking echocardiography - Includes never-published tables and figures to aid understanding of the topics - Contributions from international leading experts in the field, written with the aim of serving both researchers and practicing clinicians

Book Description
Whenever the heart is challenged with an increased work load 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 situa tions 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. Various hormones such as catecholamines, thyroid hormones, angiotensin II, endothelin, and growth factors have also been shown to induce cardiac hypertrophy. Although the exact mechanisms underlying or pathological forrns of cardiac hypertrophy are poorly under the physiological stood, an increase in the intraventricular pressure is believed to represent the major stimulus for the development of cardiac hypertrophy. In this regard, stretching of the cardiac muscle has been shown to induce the hypertrophic response, but the role of metabolic influences in this process cannot be ruled out. Furthermore, different hormones and other interventions in the absence of stretch have been observed to stimulate protein synthesis in both isolated cardiomyocyte and vascular myocyte preparations. Nonetheless, it is becoming dear that receptor as well as phospholipid linked signal transduction pathways are activated in some specific manner depend ing upon the initial hypertrophic stimulus, and these then result in an increase in the size and mass of cardiomyocytes.
