Available in PDF, EPUB and Kindle. Book excerpt: Participation in athletics at both the recreational and competitive levels has grown enormously over the last decade, and now involves a substantial segment of the population of many countries, particularly those in Europe and North America. This change in the life-style of many individuals has been accompanied by the desire and necessity on the part of physicians to define the consequences of chronic athletic training and competition to the participant. Coincident with the of public interest in sporting competition has been the evolution and growth development of new non-invasive technologies in cardiology (such as M-mode and two-dimensional echocardiography and radionuclide angiography) which have permitted investigators to study directly and more precisely the morphology and function of the heart and cardiovascular system. Hence, over the past several years our knowledge has been greatly enhanced with regard to the features of the normal 'athlete heart' and the relationship of athletic conditioning to preexistent cardiovascular disease, as well as the causes of sudden death in athletes. The present treatise on 'Sports cardiology: Exercise in Health and Cardio vascular Disease' is an impressive reference document which is also timely. It fulfills an important role in summarizing most of the available data that has been accumulated over the last 10 years in a large number of athletes participating in a variety of different sports.

Available in PDF, EPUB and Kindle. Book excerpt: W. KUPPER Coronary artery vasoconstriction is not only the mechanism responsible for Prinzmetal's variant angina, but may also be involved in stable angina pectoris and myocardial infarction. However, the underlying patho-physiological mecha nisms and the importance of coronary vasoconstriction in these syndromes is still largely unknown. Several hypotheses have been proposed. Sympathetic nervous activity plays a key role in the regulation of coronary blood flow, but mechanical or humoral constrictive factors may be active as well. a-adrenergic tone Adrenergic nerve fibers accompany coronary vessels of any size. The stimulation of cardiac sympathetic nerves causes an increase in coronary blood flow. If, however, chronotropic and inotropic effects of adrenergic stimulation are sup pressed pharmacologically by beta-adrenoceptor blockade, a reduction in flow is observed. Thus, the primary effect of sympathetic stimulation on the coronary arteries is the alpha-adrenergic mediated vasoconstriction. Functionally inner vated alpha-adrenoceptors have been documented both in large coronary con ductance arteries and in the small resistance vessels. Animal studies and a human study have documented that a permanent constrictor tone is present on the coronary circulation both at rest and during exercise; this condition could be prevented with alpha-adrenoceptor blockade or was absent after heart transplan tation. Therefore, alpha-adrenoceptor mediated coronary constriction is an at tractive hypothesis as a possible pathophysiological mechanism of inappropriate coronary vasoconstriction and cororiary vasospasm.

Download or read book Taurine and the Heart written by Heitaroh Iwata and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first Taurine Symposium organized by Dr. Ryan Huxtable and the late Dr. Andre Barbeau was held in Tucson, Arizona, in 1975. Since that auspici ous event, nine international symposia on the role of taurine in biology have taken place. The locations for these meetings have been Tucson (two times), Rome, Philadelphia, Tokyo, Vancouver, Mexico City, Helsinki, and Florence. In 1977, due to the large number of scientists in Japan who were interested in the role of this unique amino acid in biological systems, we organized the Japanese Research Society on Sulfur Amino Acids with the encouragement and financial assistance of the Taisho Pharmaceutical Co., Ltd (Tokyo). Annual meetings have been held, and the membership has expanded from 78 to 414 in 1987; the number of presentations has increased during this time span from 29 to 74. The symposium in Tokyo in 1982, "Sulfur Amino Acids, Biochemical and Clinical Aspects" [1], was held to celebrate the 5th Annual Meeting of our Society. I would like to emphasize that in Japan we have an active Research Society especially directed to the study of sulfur amino acids. We have published our own semi-annual journal entitled Sulfur Amino Acids. Our society is an inter disciplinary research society since taurine is a highly diversified compound that interconnects physiology, biochemistry, pharmacology, nutrition, and medicine. One exciting fringe benefit of taurine research and the society has been the fostering of contacts with distinguished scientists from many varied medical fields.
Download or read book Stress and Heart Disease written by R. E. Beamish and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been known or suspected for centuries that there is an association between mind and emotions and the occurrence of heart disease apd sudden death. During the past fifty years this relationship has become identified with the concept of Stress, a notion developed and popularized by Hans Selye. In recent years there has been an upward surge of interest in stress by scientists in several disciplines and by the general public. Although, books, journal articles, seminars and media programs devoted to stress now abound, the definition, manifestations, mechanisms, and management of stress remain uncertain and controversial. In an attempt to clarify the situation an International Symposium on Stress and Heart Disease was held in Winnipeg, Canada, June 26-29, 1984, and the proceedings form the basis of this book and its companion volume "Patho genesis of Stress-Induced Heart Disease". Although most species which have ever existed are now extinct through countless millenia, the human species has successfully adapted to changing conditions ("stressors") such as ice ages, predators and parasites, wars, famine and plague, and now it is coping with rapidly changing social, economic and political circumstances. Such adaptation occurs at all levels of life- at the molecular level within the cell, at the level of the whole cell, in the groups of cells as organs, in the entire organism or individual, and in some cases, in the society in which the individual lives.
Download or read book The Stressed Heart written by Marianne J. Legato and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Stressed Heart is truly unique in concept and will provide an eXCItmg adventure to the reader no matter what his or her field of expertise and interest. The title, although quite appropriate, does not adequately indicate the range of topics considered or the rational interrelationships among them. Indeed, perhaps the most important point to be learned from the book is that a serious consideration of the response of the heart to mechanical overload, ischemia, or excessive humoral stimuli must include evaluation of each of the topics in the table of contents. The heart responds to stress through alterations in both structure and function. How these changes are brought about is the subject of the initial chapters. These consider first the normal regulation of gene expression in the heart, the rapid response to mechanical overload that leads to both quantitative and qualitative changes in the contractile proteins, and our current understand ing of the signals that might be elicited by stress and alter gene expression. One chapter emphasizes the fact that, regardless of the nature of the stress, the common denominator is a discrepancy between energy requirements and expenditure. The central role of cellular acidosis in initiating the sequence of responses to stress and the possible roles of peptide regulators of transcription and protein regulators of translation are considered in detail.

This book was released on 2012-12-06 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: A recent comprehensive study of stress and human health by the Institute of Medicine/National Academy of Sciences concludes that individuals who experience any of a wide range of stressful events or situations are at increased risk of developing a physical or mental disorder, including heart disease. Since cardiovascular disease continues to be a leading cause of illness and death, and since the etiology and pathogenesis of several of the commonest forms of heart disease are incompletely known, it is of fundamental impor tance to study the potential role of stress in the genesis of heart disease. Accordingly an International Symposium on Stress and Heart Disease was held in Winnipeg, Canada, June 26-29, 1984 and the proceedings form the basis of this book and its companion volume, "Stress and Heart Disease". The connection between stress (the behavioral sciences) and heart disease (the biomedical sciences) occurs in the mechanisms through which the brain affects or controls the endocrine and the autonomic nervous systems. Initially this linkage appeared to be relatively simple, mainly involving catecholamines and corticosteroids, and communication between nerve cells was thought to be electrical. Now knowledge has increased and concepts have change dramatic ally. Major advances have occurred in biochemical, anatomical, physiological, pharmacological, pathological and behavioral aspects of the neuroendocrine system. The over whelming significance of chemical communication in the nli xviii nervous system has become clear.
Download or read book Cardiac Arrhythmias New Therapeutic Drugs and Devices written by J. Morganroth and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: In summary, there are many animal models that are useful in selecting new antiarrhythmic drugs. The selection of which model is most idea depends upon precisely what question is being asked. The large number of experimental models used to evaluate antiarrhythmic compounds points out the inability of anyone model to define the probability of antiarrhythmic efficacy in man. It has therefore become standard practice to utilize a batter of animal models for the evaluation of new antiarrhythmic agents. Each model has its own advantages and disadvantages and it is necessary to understand each model fully in oder to evaluate experimental findings and apply them to clinical settings. We believe that the availability of the chronic myocardial infarction ventricular tachyarrhythmia model provides 1) an excellent opportunity to more precisely understand arrhythmia mechanisms, 2) to develop new techniques such as signal averaging for evaluating late low level potentials identifying hearts at high risk of sudden death 3) to identify new antifibrillatory drugs versus drugs that are effective primarily against PVC's and ventricular tachycardia 4) to identify new surgical techniques to eliminate VT/VF, and 5) to evaluate new pacing modalities including implantable cardioverters. Although all animal models are wrong, many are very useful in furthering our knowledge directed at decreasing the distressingly high mortality from heart disease. NORMAL HtART TACHYCMDIA HtART , ..

Download or read book Functional Aspects of the Normal Hypertrophied and Failing Heart written by Francesco Abel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: These Proceedings are from the Fifth Annual Meeting of the American Section of the International Society for Heart Research held at Hilton Head Island, South Carolina, September 21-24, 1983. The program and abstracts were published in the Journal of Molecular and Cellular Cardiology, Vol. 15, Supplement 4, September 1983, Academic Press. This Symposium Proceedings consists of three sections. Section I deals with the mechanical factors and their i'nfluence on coronary blood flow in the normal and failing heart. Section II is developed around the area of vascular smooth muscle and the factors that may control it which ultimately play such an important role in the regulation of coronary blood flow. Section III is primarily devoted to the mechanical aspects of the function of the heart in both hypertrophy and failure including the molecular changes in the myocyte, alterations in neural control, and in inotropic responsiveness of the hypertrophied and failing heart. The editors hope that these three areas encompass a significant body of new and ongoing information that will be helpful to those who work in these areas as well as those who treat patients with varying degrees of myocardial failure or with compromised coronary circulations. The editors express their appreciation to all the contributors and to Ms. Jeri B. McClain for assisting in the organization and compiling of this volume. Francis L. Abel, M. D. , Ph. D. Walter H.

Download or read book Indications for Heart Valve Replacement by Age Group written by Carlos Gomez-Duran and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers presented at the Fifth International Symposium on Heart Valves and published in this volume discuss clinical experience with heart valve replacement in pediatric patients, in adults (age 65 and younger), and in the elderly (age 66 and older). Special considerations in heart valve replacement, such as valve selection, reoperation, results of double valve implantation, quality of life, and the use of valved conduits are also included. Finally, long term clinical follow-up with the ST. JUDE MEDICAL® heart valve, giving 7- and 8-year data is discussed. HEART VALVE REPLACEMENT IN PEDIATRIC PATIENTS Anticoagulation Anticoagulation in children is a difficult and interesting problem. Three princi pal considerations in the use of anticoagulants are patient education, timing, and anticoagulating substance. Additional considerations are patient tolerance and compliance. Generally, the findings indicate, if pediatric patients receive anticoagulation following mechanical valve replacement, it is well accepted and results in few complications. If children are not anticoagulated, complications arise. Conflicting results regarding the efficacy of PERSANTINE® and the use of aspirin vs. COUMADIN® were reported. Doctor Sade's data address some of these questions. * After a 5-year study in * See J Thorac Cardiovasc Surgery 1988; 95:533-561.
Download or read book Cardiac Left Ventricular Hypertrophy written by Henk Keurs and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Left ventricular hypertrophy (LVH) is usually considered to be a compen satory adjustment of heart muscle to an inreased work load. LVH develops in the course of valvular or congenital heart disease, or when part of the myocardium is damaged by long-standing ischemia or infarction. In the hypertrophied heart the muscle fibers increase in size, not in number. The fibers are found to contain a larger number of myofibrils and the cell organelles are larger. From epidemiologic studies it is known that even mild LVH is associated with myocardial ischemia, ventricular arrhythmias, and sudden cardiac death. Most cases of LVH show focal degenerative tissue changes including cellular atrophy, myofibrillar disorganization, interstitial fibrosis, and loss of intracellular connections. Myocardial dysfunction develops and, unlike the functional adaptive changes found in pure hypertrophy, is not reversible by surgical treatment of the valvular heart disease or medical correction of hypertension. Interstitial fibrosis, intracellular changes of musc Ie cells, and loss of contract ile tissue lead to poor mechanical function and undoubtedly increase the risk of ischemia, arrhythmias, or sudden death, a well-recognized problem in patients with a variety of heart diseases. Even When successfully treated, the patients may remain at risk if the compensatory hypertrophy is not fully reversed. Epidemiologic studies conducted in the Framingham population in the early 1950' s demonstrated LVH according to electrocardiographic criteria in 1. 5% of the population; 2% of the population had LVH according to chest X-ray criteria.
