Available in PDF, EPUB and Kindle. Book excerpt: Cardiac Dynamics is the name of a relatively young field of study, born from the fruitful interaction between branches of two different disciplines: medicine and physics. "Dynamics" is the branch of physics which deals with the action of forces on bodies or particles in motion or at rest. "Cardiac" relates to the clinical field of cardiology but also to cardiophysiology, both of which are specialized branches of medicine. Narrower than the well established field of Hemodynamics, Cardiac Dynamics is restricted to dynamic phenomena occurring in and around the heart. The mathematical treatment of such phenomena, however, is vastly more complex because of the intricate nature of the mechanisms involved in the cardiac action. Thus, whereas hemodynamics is concerned with predominantly passive (visco-) elastic structures - vessels - containing time-variant flow of viscous flui- blood -, the mechanical study of the heart requires additional con siderations such as: active elastic components representing the contractile mechanism of cardiac muscle, complex geometry and fiber structure in the myocardial wall, autoregulatory mechanisms, and intricate flow patterns associated with valve motion. Viewed in this light it is not surprising that attempts to describe ventricular pump function and to quantify contractile performance have not reached the level of sophistication which is common in e. g. arterial hemodynamics. For the same reason, many of the often simplified approaches to describe ventricular mechanics failed to stand up to more rigorous theoretical, experimental or clinical testing.

Available in PDF, EPUB and Kindle. Book excerpt: Circulatory System Dynamics reviews cardiovascular dynamics from the analytical viewpoint and indicates ways in which the accumulated knowledge can be expanded and applied to further enhance understanding of the normal mammalian circulation, to ascertain the nature of difficulties associated with disease, and to test the effect of treatment. Comprised of 10 chapters, this volume begins with an overview of the circulatory system, including its anatomy and the trigger for myocardial (heart muscle) contraction. The discussion then turns to measurement of blood pressure using invasive and non-invasive techniques; blood flow measurement, with emphasis on cardiac output and measurement in the microcirculation; the system and pulmonary arterial trees; and pulsatile pressure and flow in pulmonary veins. Subsequent chapters explore microcirculation and the anatomy of the microvasculature; the heart and coronary circulation, paying particular attention to the Frank-Starling mechanism and indices of myocardial "contractility"; and control of blood pressure, peripheral resistance, and cerebral flow. The last two chapters deal with circulatory assistance and the closed cardiovascular system. This book will be of interest to students, practitioners, and researchers in fields ranging from physiology and biology to biochemistry and biophysics.

Available in PDF, EPUB and Kindle. Book excerpt: Cardiovascular Fluid Dynamics, Volume 1 explores some problems and concepts of mammalian cardiovascular function, with emphasis on experimental studies and methods. It considers pressure measurement in experimental physiology, including the measurements of pulsatile flow, flow velocity, lengths, and dimensions; the use of control theory and systems analysis in cardiovascular dynamics; the application of computer models in cardiovascular research; the meaning and measurement of myocardial contractility; and the consequences of the steady-state analysis of arterial function. Organized into 10 chapters, this volume begins with an overview of the mammalian cardiovascular system and the essential features of cardiovascular function. It then discusses the practical problems associated with the use of pressure transducers in physiological and cardiac laboratories, the challenges involved in pulsatile flow measurement using flowmeters and thermal devices, and the mechanical analysis of the circulatory system. It explains some computer modeling techniques used in investigating the hemodynamics of the cardiovascular system, including the heart and heart muscle; basic concepts of muscle mechanics and the mechanical properties of cardiac muscle; the fluid mechanics of heart valves; and the pressure and flow in large arteries. The book concludes with a chapter on vascular resistance and vascular input impedance. This book is intended for biologists, physical scientists, and others interested in cardiovascular physiology.

Available in PDF, EPUB and Kindle. Book excerpt: This new account of the pathogenesis of essential hypertension (EH) represents a detailed analysis of the main components of the circulatory control system. The latter's properties resemble those of man-made adaptive control systems in which regulatory parameters are altered when operating conditions exceed certain limits, often through neural mechanisms. Inheritance of EH depends on both genes and environment. The high blood pressure (BP) genes have not yet been definitively identified, whilst the main environmental causes are mental stress, high dietary salt intake and obesity. EH occurs as two major syndromes, each initiated by chronic stress: 1) Stress-and-salt related EH, and 2) Hypertensive obesity. Stress is perceived by the cortex, from which increased dopaminergic (DA) neuron activity stimulates the hypothalamic defense area, raising sympathetic neural activity (SNA) and BP. Normally these subside quickly when the stress is over, but in those susceptible to EH the DA synapses become sensitized so that the defense response is evoked by ever lower levels of stress. Sensitization is common in memory circuits, but not in autonomic neurons, so that this property in EH may be genetically determined. Stress-related hypertension increases hypothalamic responsiveness to high salt, resulting in further rises in SNA and BP. Later, non-neural functional changes (e.g. reduction in nitric oxide) and the structural remodeling of resistance vessels further enhance the vasoconstriction. In contrast, in those developing hypertensive obesity food consumption is excessive, which transiently alleviates stress-related anxiety. The brain ignores the leptin-mediated signals that normally curb appetite, contrasting with normal energy regulation in SSR-EH. In hypertensive obesity, the SNA pattern is similar to that in SSR-EH, but vasoconstriction is masked by vasodilatation and fluid retention due to hyperinsulinemia. This syndrome is a volume overload hypertension, where high cardiac output, renal impairment and other non-neural factors contribute to the elevation of BP. Other topics include the role of various transmitters in autonomic regulation; the place of baroreflexes in the intact organism; why exercise training lowers resting BP; obstructive sleep apnea; non-pharmacological and drug treatment of EH; the role of the kidney in EH and in different types of renal hypertension and the pathogenesis of the Japanese spontaneously hypertensive rat, which provides a valuable animal model for EH. The work suggests that physiological systems analysis in a complex disorder like EH is a valuable tool for using the great advances in molecular biology to best advantage.

Available in PDF, EPUB and Kindle. Book excerpt: This volume constitutes the proceedings of a satellite symposium of the XXXth congress of the International Union of Physiological Sciences. The symposium has been held In Banff, Alberta Canada July 9-11 1986. The program was organized to provide a selective overview of current developments in cardiac biophysics, biochemistry, and physiology. In order to highlight areas of develop ing ideas and to stimulate the participants' inquisitiveness into the nature and complexity of the integrated cardiovascular system, lectures and discussions were presented that emphasized evolving and sometimes provocative concepts in the field. With the same goal in mind we have, for the readers of this volume, briefly summarized the general discussions. We would like to thank several individuals whose dedication made this sym posium and publication of the proceedings possible. Mrs. Lois Kokoski and Mrs. Madeleine Aldridge of the Conference Office of the University of Calgary seemingly effortlessly handled the details of the symposium. Peter de Tombe, Dr. Peter Backx and Dr. Jeroen Bucx transcribed the general discussions. Finally, we appreciate the extra effort of our secretaries, Lenore Doell and Gregory Douglas, and the work of Anna Tyberg who prepared the final manuscripts for publication.
