Cardiac Energetics
Author: R. Jacob
Publisher: Springer Science & Business Media
ISBN: 3662112892
Category : Medical
Languages : en
Pages : 410
Book Description
Assessment of cardiac energetics at the level of ATP-synthesis, chemomechanical energy transformation and whole organ dynamics as a function of haemodynamic load, ventricular configuration and oxygen- and substrates supply is basic to understanding cardiac function under physiological and pathophysiological (hypertrophy, hypoxia, ischaemia and heart failure) conditions. Moreover, cardiac energetics should be an important consideration in the choice and application of drugs especially in the case of vasodilators, inotropic agents and in cardioprotective measures. Only by considering energetics at the subcellular, cellular, and whole-heart level we can arrive at a better understanding of cardiac performance and ultimately better clinical judgement and drug therapy. Quantification of myocardial energetics will also help to determine the optimal time for surgical interventions such as valvular replacement or aneurysm resection. The present volume is the outcome of an international symposium on cardiac energetics held in Gargellen/Montafon (Austria), June 1986. The contributions will certainly help bridge the existing gap between basic research involving isolated structures and that involving the whole organ, on the one hand, and render the results derived from basic research applicable to clinical problems, on the other hand.

Nondestructive Characterization and Imaging of Wood
Author: Voichita Bucur
Publisher: Springer Science & Business Media
ISBN: 9783540438403
Category : Technology & Engineering
Languages : en
Pages : 378
Book Description
This book on the Nondestructive Characterization and Imaging of Wood by Professor Voichita Bucur is truly the most outstanding reference on the subject ever written. Since the origins of mankind, wood has played a key role in the history of humans and other living creatures, ranging from provision of life from trees giving air, heat, light, and food to nourish their bodies to structures to protect them from the elements. Wood has also played a key role in one of the world's primary religions. Nondestructive diagnostics methods have long found application in medi cal practice for examination of the human body in order to detect life threatening abnormalities and permit diagnosis to extend life. Nondestructive testing has been used for many years to insure the safety of machinery, air craft, railroads, tunnels, buildings and many other structures. Therefore, it is timely for a treatise, like the present one, to be written describing how wood can be characterized without employing destructive test methods. Since wood is so valuable to mankind, it is important to know the latest methods to nondestructively characterize wood for all practical applications.

Myocardial Damage
Author: Juan Carlos Kaski
Publisher: Springer Science & Business Media
ISBN: 940172380X
Category : Medical
Languages : en
Pages : 220
Book Description
The spectrum of unstable coronary syndromes has been the object of steadily increasing research particularly in respect of novel diagnostic and treatment modalities. Although the WHO criteria for the diagnosis of acute myocardial infarction have been known for decades, there is still much debate as to the proper use of these, especially the handling of biochemical markers. Traditional enzymes have limitations in diagnostic power and new markers have unclarified applicability with regard to standardisation of assays and decision limits. Furthermore, the growing understanding of the conception of minimal myocardial damage in the borderzone between unstable angina pectoris and myocardial infarction necessitates refinement in the definitions of the various entities within the kaleidoscope of acute myocardial ischaemia. There has been a strong impetus within the European Society of Cardiology to present this subject to a broad audience of cardiologists, and as a consequence the theme of biochemical markers has become an important constituent of the Education and Training Programmes of the Society. This book has fundamental implications for the overall comprehension of this complex area. This book on myocardial damage, compiled by international experts, will truly appeal to the basic scientist as well as the clinician searching for updated knowledge of the pathophysiology and risk stratification of unstable coronary syndromes.

Cardiovascular Genetics for Clinicians
Author: P.A.F.M. Doevendans
Publisher: Springer Science & Business Media
ISBN: 9401010196
Category : Medical
Languages : en
Pages : 256
Book Description
All physicians practicing medicine encounter patients suffering from cardiovascular disease. This book has been outlined in such a way that vascular surgeons, general internists, neurologists and cardiologists should be able to use it. The book covers the complete scope of cardiac diseases in addition to chapters on hypertension and atherosclerosis. In many patients there is a family history of cerebrovascular accidents, myocardial infarction or peripheral arterial disease. Also in patients reporting collaps, palpitations and arrhythmias the family is crucial and can provide clues to a genetic cause of the disease. This book is published to guide physicians in the process of determining whether a genetic component is likely to be present. Furthermore, information is provided what the possibilities and limitations of DNA diagnostic techniques are. Finally, the importance of newly identified categories of potential patients, i. e. gene carriers without symptoms or any inducible sign of disease, is highlighted. For some patients a genetic diagnosis is essential to determine appropriate therapy and for counseling? In some other diseases DNA diagnostic tools are available but the relevant for the patients may be less clear. In other families the search for a disease causing gene is ongoing and the possibilities to find genes and to unravel the pathophysiology of the disease is limited by the lack of patients. To give insight into the current state of genetic diagnostics, the authors have classified the cardiovascular diseases.

Delayed Preconditioning and Adaptive Cardioprotection
Author: G.F. Baxter
Publisher: Springer Science & Business Media
ISBN: 9401153124
Category : Medical
Languages : en
Pages : 240
Book Description
Interest in the ability of myocardium to adapt to ischaemic stress has continued to grow since the discovery of ischaemic preconditioning in 1986. In 1993, two reports heralded the recognition of a delayed preconditioning response in the heart, now commonly known as the `second window' of protection. Since then, a number of studies have described the ability of delayed preconditioning and related adaptive phenomena to protect against a variety of pathologies in the ischaemic and reperfused myocardium. Our understanding of the cellular mechanisms of sub-acute adaptive cardioprotection has advanced considerably during this period. This compilation of state-of-the-art reviews by those who have made significant contributions to this field provides detailed and critical analysis of this research, from molecular basis to potential clinical relevance. The book aims to provide an authoritative, comprehensive and thoroughly up-to-date overview for scientists and clinicians engaged in, or observing, this rapidly-developing area of heart research. It will also be of interest to those engaged in research on other tissues where ischaemia-reperfusion pathology is of major concern.

Cardiovascular Specific Gene Expression

ISBN: 9401593213
Category : Medical
Languages : en
Pages : 328
Book Description
Improving our insights into the genetic predisposition to cardiovascular disease is one of the most important challenges in our field in the next millennium, not only to unravel the cause of disease but also to improve the selection of patients for particular treatments. Nowadays, for example, subjects with a cholesterol above a particular plasma level are exposed to a cholesterol lowering regime based upon the beneficial outcome of epidemiological studies which include subjects not prone to the disease, despite a plasma cholesterol above the accepted level. Identification of the patients who are genetically predisposed to the consequences of this disorder will reduce the number of subjects unnecessarily treated and, hence, the costs of health care. Because in most cardiovascular diseases the genetic component is a consequence of more than one gene defect, only limited progress has as yet been made in identifying subjects genetically at risk. For example, in hypertension only in less than 10% of the patients the genetic defect has been identified. It has been known for quite some time that in heart and blood vessels fetal genes are as high blood pressure and upregulated or induced when they are exposed to such disorders ischemia. Little is known about the function of these genes in the cardiac and vascular adaptation to these disorders; only guesses can be made.

Chronic Infection, Chlamydia and Coronary Heart Disease
Author: S. Gupta
Publisher: Springer Science & Business Media
ISBN: 0585375984
Category : Medical
Languages : en
Pages : 160
Book Description
Coronary heart disease (CHD) remains a major cause of human mortality and morbidity worldwide. Classical risk factors for atherosclerosis fail to account fully for the wide variations in CHD prevalence and/or severity between differing populations. The search for hitherto unrecognised risk factors has recently focused on the potential role of chronic inflammation and common infections. Chronic Infection, Chlamydia and Coronary Heart Disease is the first book to review the wealth of evidence linking various infective agents with CHD, focusing particularly on the proposed pathogenetic role of the main candidate microorganism, Chlamydia pneumoniae. Written by two leading investigators in the field, the book provides a concise, clearly written and up-to-date account of the diverse lines of evidence - seroepidemiological, pathological, animal and in vitro data and clinical antibiotic trials. The possibility of an infective basis to atherosclerosis and CHD has already attracted much scientific interest. Chronic Infection, Chlamydia and Coronary Heart Disease highlights the key published works on the topic, and concludes with information on existing, ongoing, and future lines of enquiry.

Surgical Options for the Treatment of Heart Failure
Author: R. Masters
Publisher: Springer Science & Business Media
ISBN: 0585291918
Category : Medical
Languages : en
Pages : 202
Book Description
Despite the significant decline in heart disease mortaht>' rates over the last 25 years, heart failure has remained a significant problem. We are now confronted with large numbers of terminally ill patients for whom conventional therapies for heart failure have been exhausted and for whom repeated hospital visits are necessary. There now is a major thrust towards a management strategy which embraces a comprehensive approach including vigorous preventive measures and earlier surgical interventions. This book outlines the major surgical options for the treatment of heart failure and brings together a very broad base of opinions with contributions from several outstanding individuals. With the improved knowledge and techniques to control rejection, transplantation has become the central pillar in the surgical management of this group of patients. Unfortunately, because of limited donor supply the teclmique cannot be applied to large numbers of patients. A great deal of excitement, however, exists in the potential for xenotransplantation as a supplement to homotransplantation. The use of cardiac assist devices has become a reality with several hundred LVADS and BiVADS implanted throughout the world and cardiac replacement with total artificial hearts continues to be used successfully as a bridge to transplantation. We are on the thieshold of the broad application of assist devices to provide prolonged relief of heart failure and restore patients to an ambulatoiy home environment and hopefully return to the work force in significant numbers.
