Advances in cellular physiology and molecular biology have now disclosed the metabolic changes and adaptational responses of the heart to various kinds of stresses. Topics covered in this volume include the regulation of myocardial proteins in mechanical overload, the alteration of adrenoceptors in the stressed heart, metabolic adaptation in cardiac hypertrophy, intracellular calcium metabolism in the ischemia-reperfused myocardium, calcium overload as a cause of myocardial stunning, acquisition of ischemic tolerance by ischemic preconditioning, factors that accelerate myocardial injury, and ventricular remodeling in the ischemic heart. As an update of the latest findings in basic cardiology, this book will benefit both researchers and clinical practitioners.

Cardiac performance is regulated not only by cardiac muscle properties but also by several other factors, including those associated with the neurohumoral system and the mechanical characteristics of the peripheral circulation. New information con­ cerning these regulatory factors has furthered our understanding of the pathophysi­ ology of cardiac dysfunction. However, controversy remains, along with a need to integrate these multidisciplinary findings. It was with this in mind, together with my continuing interest in the response of the normal and diseased heart to variations in loading conditions, that the satellite symposium entitled "Interactions Between Car­ diac Function and Vascular Dynamics" was organized and dedicated to my mentor, Dr. T. Takishima. The symposium was held in Fukushima, Japan, in 1992 following the Tenth Inter­ national Conference of the Cardiovascular Systems Dynamics Society in Kobe, Japan, which was organized by the then president of the society, Dr. Masatsugu Hori. The Fukushima symposium and the Kobe conference were stimulating and informative. To commemorate these events, Dr. Hori, Dr. Janicki, and I decided to publish this book. It covers topics that were presented then as well as pertinent new material. As a result, the book includes not only updated reviews but also up-to-date findings that were not considered at the two scientific sessions. The high level attained in this book is due to the outstanding contributions from internationally renowned scientists. This final product of their efforts should prove to be a valuable source of information to the reader.

Coronary circulation research is advancing at a rapid rate. Not only are inno­ vative techniques for studying myocardial perfusion being developed, new mechanisms related to coronary blood flow control and mechanics are also being discovered. The progress in this field justifies an update in the form of this new monograph. The book is divided into the following sections: "Measurement of Coronary Blood Flow and Assessment of Myocardial Per­ fusion" discusses advances in perfusion measurements in humans as well as nonradioactive microsphere methods. . "Coronary Flow Dynamics" elucidates the effect of heart contraction on coronary flow, perfusion, and reserve distribution as well as systolic-diastolic interaction. Models-a frequent topic of debate-are used to quantify hypotheses. "Models of Coronary Circulation" attempts to elucidate the concept of tissue pressure. "Regulatory Mechanisms of Coronary circulation and its Clinical Relevance": N u.merous mechanisms affecting coronary flow have been defined and studied at the level of isolated vessels and whole organs. The chapters in this section provide an in-depth analysis of a selection of these mechanisms and their inter­ actions. "Pathophysiology of Coronary Circulation in Ischemic Heart Disease" considers important aspects of factors which restrict perfusion of the myocardium in ischemic heart disease. An understanding these factors is of crucial importance in the management of patients. "Small Vessel Disorder in Coronary Circulation" describes circulatory flow and how it can be influenced by drugs.
