The fields of biological and medical physics and biomedical engineering are broad, multidisciplinary and dyanmic. They lie at the crossroads of frontier - search in physics, biology, chemistry, and medicine. The Biological & Me- cal Physics/Biomedical Engineering Series is intended to be comprehensive, covering a broad range of topics important to the study of the physical, che- cal and biological sciences. Its goal is to provide scientists and engineers with textbooks, monographs, and reference works to address the growing need for information. Books in the series emphasize established and emergent areas of science - cluding molecular, membrane, and mathematical biophysics; photosynthetic - ergy harvesting and conversion; information processing; physical principles of genetics; sensory communications; automata networks, neural networks, and cellular automata. Equally important will be coverage of applied aspects of b- logical and medical physics and biomedical engineering such as molecular el- tronic components and devices, biosensors, medicine, imaging, physical prin- ples of renewable energy production, advanced prostheses, and environmental control and engineering.

by JULIEN IE HOFFMAN One of the earliest coronary physiologists was Scaramucci who, in 1695, postu lated that during systole the contracting myocardium inhibited coronary blood flow. Since then, the many contributions that have been made to our knowledge of the coronary circulation can be arbitrarily divided into three phases based on advances in technical methods. The early phase of research into the coronary circulation, done with great difficulty with crude methods, may be regarded as ending in the 1940s, and it included major discoveries made by such well known investigators as Georg von Anrep, Ernest Starling, Carl Wiggers, and Louis Katz, who formulated much of our basic understanding of the field. After 1940, the field of coronary physiology entered a new phase when instruments for high fidelity registration of coronary flow and pressure became available. This era was domi nated by Donald Gregg who combined careful attention to the function of these instruments (some of which he helped to develop) with an extraordinary ability to discern mechanisms from apparently minor changes in coronary flow and pressure patterns. His book 'The Coronary Circulation in Health and Disease' set a new standard in the field. After 1960, techniques for measuring regional myocardial blood flow became available, and enabled a large group of eminent investigators to make major advances in understanding the physiology and pathophysiology of myocardial blood flow.

Research centering on blood flow in the heart continues to hold an important position, especially since a better understanding of the subject may help reduce the incidence of coronary arterial disease and heart attacks. This book summarizes recent advances in the field; it is the product of fruitful cooperation among international scientists who met in Japan in May, 1990 to discuss the regulation of coronary blood flow.

The book describes Dr. Sevelius' long career as medical scientist, pursuing specifically what can be learned from a radiocardiogram (RCG), the recording through the skin of the heart flow, the cardiac output (CO), the most fundamental of all body functions. The RCG has been slow in acceptance in clinical medicine. One worry has been the radiation. The radiation is approximately one-third that of a chest x-ray and should be of minor concern with proper education. Another difficulty is how to interpret the results. Other techniques for CO measurements have had similar problems, not because the techniques were wrong but because the interpretation was based on wrong premises with too wide a standard deviation for proper diagnosis in clinical work. Dr. Sevelius introduces two new assessments: hemodynamic and metabolic. With these interpretations the heart as a pump is first judged according to the size of simultaneously measured blood volume it has to pump and second, separately, as to how large a body the heart has to supply with oxygen. The hemodynamic evaluation of the heart flow is found to be a good predictor to a within six-month pending heart attack. This would make the RCG an exceptionally simple and useful tool for diagnosis in clinical medicine. This book collects Dr. Sevelius' work in digital format to make it easily available. It is Dr. Sevelius' hope that his work will inspire some young scientists to follow up his work because of its wide application in modern medicine.

Ischemic heart disease is the leading cause of morbidity and mortality in the developed world. The high metabolism and oxygen demand of the cardiac myocardium depends on both a high blood flow and a rich capillary density. For this reason, the growth of the coronary vasculature is vital, not only in early development, but also in the adult faced with various stresses. Novel technologies have enabled the discovery of the molecular mechanisms underlying the growth and assembly coronary vessels, and this volume covers the hierarchy of the coronary vasculature from its embryonic origins through its postnatal growth, adulthood, and senescence. Chapters address normal coronary development, coronary anomalies and their possible underlying developmental errors, coronary vessel adaptations to exercise training, aging, hypoxia, myocardial ischemia, and cardiac hypertrophy. This comprehensive overview of current research in coronary vessels and myocardial perfusion was written by Dr. Robert J. Tomanek, Emeritus Professor of Anatomy and Cell Biology at the University of Iowa. The book reviews, discusses, and integrates findings from various areas of coronary vasculature research, and as a result, will be a valuable reference source for cardiovascular scientists and physicians for many years to come.
