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.
Download or read book Brain and Heart Dynamics written by Stefano Govoni and published by Springer. This book was released on 2020-07-31 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This ambitious and comprehensive handbook represents an essential contribution to our current understanding of interactions between heart and brain, a research topic generating growing interest. Despite the increasing awareness that neural mechanisms are the primary cause of cardiac disease and its progression, therapy continues to focus on end-organ protection and does not approach the neural core of the problem. Growing public health problems such as heart failure are still treated with autonomic drugs that are 30-40 years old and simply act on cardiac receptors. However, it has now been shown that the progression of ischemic heart disease to heart failure is mainly due to abnormal central responses to incipient cardiac disease, with neural activation the primary cause rather than the consequence of cardiac remodeling. Written by leading international experts in their respective research areas, the book presents a variety of perspectives on the core topic: from social and philosophical to gender-related aspects. It is designed for a broad readership and includes dedicated sections for cardiologists, psychiatrists, neurologists and psychotherapists looking for a more insightful and targeted approach to neuro-cardiovascular disease.

Available in PDF, EPUB and Kindle. Book excerpt: Comparative Cardiovascular Dynamics of Mammals offers never-before-published data on the structure and function of the circulatory systems of the different mammalian species. This text explores classic allometry, dimensional analysis, and modern hemodynamics to establish similarity principles that provide a necessary and important step in understanding the natural common design and functional features of the cardiovascular systems of different mammals. Fluid and blood vessel mechanics, pulse transmission characteristics, cardiac energetics and mechanics, as well as heart-arterial system interaction are included in this essential reference. The sensitivity of parameters and similarity of principles in the diagnosis of cardiovascular diseases are also addressed. This book also describes the natural processes involved in the functional development of the mammalian cardiovascular system. By using modern methods to present recent findings on the similarities and differences of the mammalian cardiovascular system, the author provides an easily understood approach to this dynamic field of study.

Download or read book Circulatory System Dynamics written by Abraham Noordergraaf and published by Elsevier. This book was released on 2012-12-02 with total page 368 pages. 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.
