This book was released on 2012-12-06 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stunning is potentially an important complication of myocardial reperfusion. In contrast, hibernation is an important complication of myocardial ischemia. This book presents different viewpoints on these subjects, taken from a series of peer-reviewed articles which first appeared in Cardiovascular Drugs and Therapy, and now in this book. In addition, a certain number of articles were directly invited for the book. The introductory article is by Eugene Braunwald, who with Kloner introduced the term myocardial stunning in 1982. The experimental phenomenon had first been described by Heyndrickx et al. This important concept of stunning is examined from a number of points of view in a series of articles which clarify the experimental causes and the clinical implications. The section on hibernation is introduced by Tubau and Rahimtoola, the latter having first propounded the concept in 1989. The difference between stunning and hibernation is that stunning is essentially a post-ischemic dysfunction of the myocardium, temporary in nature, occurring at a time when coronary blood flow is apparently normal or supranormal. Hibernation, on the other hand, is a condition of reduced contractile activity, the direct result of chronic ischemia and hence a sign of a tolerable reduction in blood flow. Possibly the reduction in contractile activity of the hibernating heart balances the reduction in the oxygen availability (the `smart heart' of Rahimtoola). This non-contractile heart is hibernating, awaiting the return of summer after winter, and willing to contract normally again whenever warm coronary blood is restored. It is certain that the concepts of stunning and hibernation are here to stay, that they have or will have clinical relevance, and that the search for the most appropriate diagnosis and therapy for each condition is now under way. Hence, a greater understanding of the experimental work which underlies these two conditions is highly appropriate.

Download or read book Stunning Hibernation and Preconditioning written by Guy R. Heyndrickx and published by Lippincott Williams & Wilkins. This book was released on 1997 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph aims to summarize and integrate knowledge regarding the intrinsic adaptive mechanisms of the heart triggered by ischemia. The contributors review the initial adaptation to ischemia and the concept of preconditioning. Close attention is given to knowledge of myocardial stunning, including the role of calcium homeostasis and oxyradicals as well as the clinical impact and pharmacological modulation of myocardial stunning. Myocardial hibernation and its link with myocardial stunning are also discussed. The contributors attempt to integrate experimental data and clinical observations. The understanding of the basic pathophysiological mechanisms of these ischemic syndromes should help readers to correctly identify and treat patients with chronic ischemic left ventricular dysfunction.

Available in PDF, EPUB and Kindle. Book excerpt: Detailed analyses of regional myocardial blood flow, function, metabolism and morphology in ischemic and reperfused myocardium have led to the identifi cation of important phenomena, i. e. , myocardial hibernation, myocardial stun ning and ischemic preconditioning. Both the hibernating and the stunned myocardium characterize viable though dysfunctional as distinguished from necrotic tissue. With the advent of reperfusion procedures, the distinction between reversibly injured, hypofunctional myocardium from irreversibly injured, hypofunctional myocardium is of utmost clinical importance. The pathophysiological distinction of hibernating and stunned myocardium is con troversial, but reperfusion is mandatory anyway. Ischemic preconditioning is the most powerful maneuver known so far to delay infarct development. Its clinical significance has been suggested from retrospective analyses of data from patients suffering a myocardial infarction as well as from controlled PTCA studies. Whether or not preconditioning can be achieved pharmacologically in the clinical setting remains to be established. The mechanisms and signal cascade underlying myocardial hibernation, myocardial stunning and ischemic preconditioning are not clear in detail. Over the last year, focussed issues on myocardial hibernation, myocardial stunning and ischemic preconditioning were published in Basic Research in Car diology; they have received great interest and a good response. Therefore, these focussed issues are now combined and published as a separate monograph. We express our gratitude once more to all our colleagues who contributed to this monograph, to Ms. Ibkendanz of Steinkopff, and to Ms. Philipp and Mr. Heinrichs from Bayer AG Germany, who supported this additional publication.

Available in PDF, EPUB and Kindle. Book excerpt: About the Book There are vast amounts of new data emerging in the study of calcium antagonist drugs. The major issues involved are no longer just the effects of calcium antagonist drugs in angina or hypertension but their possible postinfarct protective effects, both to provide prophylaxis and to improve left ventricular function. New trials have also changed our thinking. One major trial suggested that the use of one of these agents in postinfarct patients with no history of heart failure in the acute infarct stage was not only safe but could confer positive protection from reinfarction and possibly from sudden death. Another study, also in postinfarct patients but with a different agent, has drawn attention to a further unexpected benefit, namely improvement of mechanical diastolic function. In the area of hypertension, the emphasis has shifted to the regression of left ventricular hypertrophy, now recognized as an independent risk factor for cardiovascular mortality, and to diastolic dysfunction. Looking to the future, calcium antagonists may exert protection against end-stage heart failure by limiting left ventricular hypertrophy and by vascular beneficial effects. There is emerging interest that the combination with ACE inhibitors may exert additive effects on control of hypertension and on diabetic hypertensive renal lesions.

Download or read book Cardiac Cell Biology written by Elissavet Kardami and published by Springer Science & Business Media. This book was released on 2003-02-28 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cardiac cell biology has come of age. Recognition of activated or modified signaling molecules by specific antibodies, new selective inhibitors, and fluorescent fusion tags are but a few of the tools used to dissect signaling pathways and cross-talk mechanisms that may eventually allow rational drug design. Understanding the regulation of cardiac hypertrophy in all its complexity remains a fundamental goal of cardiac research. Since the advancement of adenovirally mediated gene transfer, transfection efficiency is no longer a limiting factor in the study of cardiomyocytes. A limiting factor in considering cell transplantion as a strategy to repair the damaged heart is cell availability at the right time. Cardiac gap junctions, intercellular communication channels that allow electrical and metabolic coupling and play an important role in arrhythmogenesis are now understood to be exquisite sensors of cardiac change. The reports in this volume incLude elegant studies that made use of cutting edge technological advances and many specialized reagents to address these issues.

All reviews address recent and rather controversial issues on purines and myocardial protection. Mechanisms of cardioprotection of exogenous versus endogenous purines are discussed in detail. The contribution of internationally recognized experts in the field of purines and cardiovascular physiology and in myocardial protection makes this a unique and interesting book for clinicians, basic scientists and students.

Download or read book Myocardial Ischemia written by Dennis V. P. Cokkinos and published by Springer Science & Business Media. This book was released on 2006-03-08 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective new treatments of heart disease are based on a refined understanding of cellular function and the heart's response to environmental stresses. Not surprisingly therefore, the field of experimental cardiology has experienced a phase of rapid expo nential growth during the last decade. The acquisition of new knowledge has been so fast that textbooks of cardiology or textbooks of cardiovascular physiology are often hard-pressed to keep up with the most important conceptual advances. Witness the explosive increase in knowledge about signaling pathways of cardiac growth, transcrip tional regulation of cardiac metabolism, hormonal signaling, and the complex responses of the heart to ischemia, reperfusion, or ischemic preconditioning. This book is meant to bridge the gap between original literature and textbook reviews. It brings together inves tigators of various backgrounds who share their expertise in the biology of myocardial ischemia. Each chapter is a self-contained mini-review, but it will soon become apparent to the reader that there is also a common thread: Molecular and cellular cardiology has never been more exciting than now, but ever more exciting times are yet to come.

This book was released on 2010-10-05 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past ?fty years, advanced techniques and strategies have arisen in the ?eld of myocardial protection. Meticulous trials, focusing on pulmonary protection during heart surgery requiring cardiopulmonary bypass (CPB), have been missing. This te- book is intended to serve as a useful tool to spread information on strategies for lung protection during heart surgery with CPB. Emphasis on pulmonary protection will be turned to lung perfusion as an adjunct for minimizing the deleterious effects of pulmonary ischemia-reperfusion injury in heart surgery. Many renowned authors have contributed by presenting their expe- ence on lung perfusion in basic research and clinical trials. Furthermore, they have enlightened the quality of this textbook with new ideas, concepts, and future perspectives. The scope of this textbook is of interest to different professionals, such as card- vascular surgeons, pulmonary surgeons, transplantation physicians, cardiothoracic anesthesiologists, intensive care physicians, cardiothoracic fellows, radiologists, basic sciences physicians, cardiologists, pulmonary medicine physicians, perfusi- ists, nurses, students, and researchers. This textbook has 7 sections, aimed at addressing general and speci?c aspects of pulmonary protection during heart surgery with CPB. The ?rst section on general concepts provides information about anatomic, physiologic, histologic, molecular, and radiologic considerations regarding the lungs. The second section focuses on ischemia-reperfusion injury and is composed of several interesting chapters, addressing the basic science aspects of pulmonary p- tection, as well as experimental and clinical experiences from different heart surgery centers worldwide.
