Book excerpt: The myocardium in heart failure: Cellular and subcellular alterations in the failing human myocardium. H. Just Medizinische Universitatsklinik Freiburg i. Br., Innere Medizin III - Kardiologie, FRG The syndrome of heart failure continues to be a major challenge to clinicians and scientists. Incidence and mortality of the disease are high, the patient is disabled, and is permanently threatened by the high morbidity and mortality. The clinician faces a syndrome of complex pathophysiology. Multiple causes or underlying disorders of the heart have to be differentiated from heart failure itself, which often results in exceedingly difficult diagnoses. Likewise, prognostication meets with difficulties due to problems in separating influences of the underlying disease and the heart failure syndrome itself. In chronic refractory failure annual mortality may exceed 50%. If aortic stenosis or ischemic cardiomyopathy with main stem lesions are present, this percentage may be even higher. The situation becomes particularly threatening to the patient when the reduction in cardiac performance goes along with complex ventricular arrhythmias. Therapy has remained difficult and of limited effectiveness. Major progress was achieved with the introduction of diuretic substances. Of similar importance was the introduction of va so dilating drugs into the treatment of heart failure. The principle of vasodilation has greatly improved our understanding of the disease, and has brought about a major improvement of symptoms, increase of exercise capacity, and reduc tion of mortality. This is especially true for the introduction of the angiotensin converting enzyme inhibitors.

This book was released on 2012-04-09 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alteration of excitation-contraction coupling in the failing human heart was deemed an interesting subject for a dialogue between basic scientists and clinical researchers in continuation of previous Gargellen Conferences concerned with the function of the normal and failing human myocardium. In 1987 basic mechanisms and clinical implications of then new insights into cardiac energetics was followed by a comprehensive review of inotropic stimulation and myocardial energetics in 1989. Here, we undertook a re-evaluation of the principles of inotropic stimulation and of its potential therapeutic value, based on new observa tions from experiments with human myocardium. In 1992 the risk due to myocardial phenotype change as a consequence of adaptation in heart failure was published. Here, alterations of subcellular structures and functions as a consequence of chronic heart failure, summarized as phenotype change, could be described as an essential characteristic of the failing human myocardium. This topic was discussed in greater depth in the volume "Cellular and Molecular Alterations in the Failing Human Heart", considering both the sarcolemma and the phosphodiesterases, as well as excitation-contraction coupling and contractile proteins, extracellular matrix, and mitrochondrial function.

Download or read book Cardiac Adaptation in Heart Failure written by J. Holtz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, cardiac hypertrophy is regarded as an adaptation of the heart to permanent mechanical overload. Regardless of the fact that many different and often unknown primary causes can result in heart failure, mechanical overload and myocardial hypertrophy is found in almost all forms of manifest chronic heart failure (apart from failure due to extramyocardial hindrances to inflow or to relaxation). However, the reactive enlargement of myocardial mass in response to an enhanced hemodynamic burden appears to be a double-edged sword. Obviously, the hypertrophy helps to reduce the enhanced ventricular wall stress in heart failure by adding contractile units to the overdistended chamber wall. However, in recent years it became clear that this adaptive hypertrophic process is rather complex and may include problematic facets. The adaptive hypertrophy includes proliferation of the nonmyocyte cardiac cells as well as substantial alterations in the phenotype of the growing myocytes due to differential changes in gene expression.
Download or read book Heart Metabolism in Failure written by R.A. Altschuld and published by Elsevier. This book was released on 1998-09-21 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heart failure continues to be a major public health problem in the United States with close to half a million new cases diagnosed each year. Moreover, deaths from heart failure are on the increase, in part because of advances in the treatment of other fatal diseases, and in part from the prevalence of lifestyles indifferent to the risk factors for heart disease. This is not to say that no progress has been made in the treatment of heart failure. While for many years treatment was confined to the management of the symptoms, in recent years with the advent of ACE inhibitor and ß blacker therapies, real improvements in cardiac function and life expectancy have been achieved (Volume 4B, Leier). On a more basic level, enormous advances have been made in describing many of the changes in structure and function of the heart and the parallel neurohumoral and circulatory adaptations that occur during the onset of failure. These advances have been made not only by using various animal models of heart failure, but also using fresh failing human heart tissue, which has become readily available for experimental investigation since the advent of cardiac transplantation. Understanding the significance of many of these changes that occur during the transition to failure and the role they play in the etiology of failure is, however, a much more difficult task. These are exciting times in heart failure research. It is as though many of the pieces of the jigsaw puzzle are available but the puzzle has yet to be assembled. The objective of these volumes is to bring together some advances that have been made in recent years in defining one aspect of the failing heart, that is, the role of altered metabolism, in order to facilitate assembly of the puzzle.

Download or read book Analytical and Quantitative Cardiology written by S. Sideman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tenth Henry Goldberg Workshop is an excellent occasion to recall our goals and celebrate some of our humble achievements. Vision and love of our fellow man are combined here to: 1) Foster interdisciplinary interaction between leading world scientists and clinical cardiologists so as to identify missing knowledge and catalyze new research ideas; 2) relate basic microscale, molecular and subcellular phenomena to the global clinically manifested cardiac performance; 3) apply conceptual modelling and quantitative analysis to better explore, describe, and understand cardiac physiology; 4) interpret available clinical data and design new revealing experiments; and 5) enhance international cooperation in the endless search for the secrets of life and their implication on cardiac pathophysiology. The first Goldberg Workshop, held in Haifa, in 1984, explored the interaction of mechanics, electrical activation, perfusion and metabolism, emphasizing imaging in the clinical environment. The second Workshop, in 1985, discussed the same parameters with a slant towards the control aspects. The third Goldberg Workshop, held in the USA at Rutgers University, in 1986, highlighted the transformation of the microscale activation phenomena to macro scale activity and performance, relating electrophysiology, energy metabolism and cardiac mechanics. The fourth Goldberg Workshop continued the effort to elucidate the various parameters affecting cardiac performance, with emphasis on the ischemic heart. The fifth Workshop concentrated on the effect of the inhomogeneity of the cardiac muscle on its performance. The sixth Workshop highlighted new imaging techniques which allow insight into the local and global cardiac performance.
Download or read book Molecular Cardiology for the Cardiologist written by Bernard Swynghedauw and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular Cardiology for the Cardiologist, Second Edition provides a short, easily readable summary of what the new biology brings to cardiology. Special efforts have been made to include comprehensive diagrams and drawings, as well as teaching tables, and also to keep the size of the second edition within the modest limits of the first edition. The book remains divided into 5 parts. The first part is a general introduction to the new terminology. The second part is devoted to the normal structure of the heart and vessels. Parts 3 and 4 deal with physiopathology. One of the important contributions of molecular biology to cardiology is a better understanding of the general process of adaptation of the heart and vessels to a permanent mechanical overloading. Such a process is generally called remodeling, and results from coordinate changes in the expression of the genes. The last part of the book includes information on gene and cellular therapy.

Available in PDF, EPUB and Kindle. Book excerpt: In the last decade, ACE inhibitors have become a cornerstone of cardiovascular drug therapy. Beneficial effects in patients with hypertension, heart failure, and post myocardial infarction have been established in large clinical trials. In parallel, ex perimental research has shifted the interest from the immediate homeostatic function of the circulating renin-angiotensin-system to the multiple paracrine functions of local tissue renin-angiotensin-systems, including hypertrophy, hyperplasia, athe- oenesis, and vasomotion. . It was the aim or a symposium held in Hamburg, October 22-24, 1992, to bring together an international panel of experimental and clinical scientists and to discuss the most recent findings on the role of angiotensin and associated mediators in car diovascular adaptation and disease, with a particular emphasis on the treatment of such disease by ACE inhibitors.
