Book Description
Stress-induced myocardial ischemia is a frequent manifestation of coronary heart disease, and sympathetic activation is an important precipitating and aggravating factor in such stress induced ischemia. However, the complex interplay between the sympathetic initiation of myocardial ischemia, ischemia-induced alterations in sympathetic neurotransmission, as well as changes in adrenoceptor density and post-receptor signal transduction that can occur during ischemia remains incompletely understood. Not only the activation of myocardial fJ adrenoceptors, but also the activation of coronary IX-adrenoceptors can contribute to myocar dial ischemia. However, the role of fJ-adrenoceptor-mediated increases in contractility relative to heart rate in the initiation of ischemia is not clear, and the significance of IX-adrenoceptor mediated changes in coronary vasomotor tone, as well as the responsible IX-adrenoceptor subtypes are highly controversial. Malignant arrhythmias may be triggered by both IX- and fJ-adrenergic mechanisms. Current research in this field is focussed not only on the underlying physiological and pathophysiological mechanisms, but also on clinical treatment strategies, e. g., by fJ-blockade, IX-blockade, bradycardic agents and calcium antagonists. Recent findings were presented and future research directions discussed during the 61" International Titisee Conference, held at the Schwarzwald-Hotel, Titisee, March 29-31, 1990 under the sponsorship of the Boehringer Ingelheim Foundation. Dr. Hasso Schroeder and Dr. Hermann Frohlich deserve special thanks for their generous support and pleasant organization of the meeting. The publication of the proceedings has been made possible by grants from Astra Chemicals, Bayer, ICI, Dr. Karl Thomae, and Upjohn

Myocardial Ischemia: Mechanisms, Reperfusion, Protection
Author: Morris Karmazyn
Publisher: Springer Science & Business Media
ISBN: 9783764352691
Category : Medical
Languages : en
Pages : 538
Book Description
Myocardial ischemia and subsequent reperfusion of the ischemic myocardium represent complex phenomena encompassing numerous physiological processes. This book aims at enhancing our understanding of these processes and stresses recent important developments in this very active area of research. The concise, state-of-the-art reviews cover recent advances in many fields important to the area of myocardial ischemia and reperfusion including physiology, pathology, pharmacology, biochemistry and molecular biology with reference to clinical relevance and applicability of these findings. Major areas which are highlighted include vascular mechanisms resulting in myocardial ischemia, cellular events in the ischemic, postinfarcted and reperfused myocardium as well as new exciting developments in cardiac protection that involve both novel pharmacological approaches as well as endogenous cardioprotective mechanisms such as preconditioning. Aimed at both the basic and clinical cardiovascular investigator, the book comprehensively reviews the rapid progress made in recent years in understanding the etiology of myocardial ischemia and reperfusion. It will further serve as an authoritative reference for all those interested in learning about the important developments in the treatment of myocardial ischemic and reperfusion disorders.

Myocardial Ischemia and Preconditioning
Author: Naranjan S. Dhalla
Publisher: Springer Science & Business Media
ISBN: 1461503558
Category : Medical
Languages : en
Pages : 564
Book Description
Current evidence suggests that the ischemic preconditioning response is a multi-factorial process consisting of an initial early trigger, an intermediate mediator, and an end effector. Each of these steps in is now its own intense area of investigation. The need to render the heart ischemic for a brief period to invoke the preconditioning response is currently the major factor limiting clinical application of this powerful cardioprotective strategy. Recent research efforts have utilized brief exposures to pharmacological agents, in lieu of a brief preconditioning ischemia, to trigger/mimic the ischemic preconditioning-induced response. The World Heart Congress held in Winnipeg in July 2001 provided a forum for the presentation of new insights into the basic mechanisms of ischemia and reperfusion injury, as well as novel strategies to protect the heart from cell death, ventricular arrhythmias, and contractile dysfunction. Many pioneers in the fields of ischemia-reperfusion injury and preconditioning-induced protection presented there and the chapters in this book represent selected papers from these symposia.

Coronary Microvascular Dysfunction
Author: Filippo Crea
Publisher: Springer Science & Business Media
ISBN: 8847053676
Category : Medical
Languages : en
Pages : 263
Book Description
In the past two decades a number of studies have shown that abnormalities in the function and structure of coronary microcirculation can be detected in several cardiovascular diseases. On the basis of the clinical setting in which it occurs, coronary microvascular dysfunction (CMD) can be classified into four types: CMD in the absence of any other cardiac disease; CMD in myocardial diseases; CMD in obstructive epicardial coronary artery disease; and iatrogenic CMD. In some instances CMD represents an epiphenomenon, whereas in others it represents an important marker of risk or may contribute to the pathogenesis of myocardial ischemia, thus becoming a possible therapeutic target. This book provides an update on coronary physiology and a systematic assessment of microvascular abnormalities in cardiovascular diseases, in the hope that it will assist clinicians in prevention, detection and management of CMD in their everyday activity.

Book Description
The Social Security Administration (SSA) uses a screening tool called the Listing of Impairments to identify claimants who are so severely impaired that they cannot work at all and thus immediately qualify for benefits. In this report, the IOM makes several recommendations for improving SSA's capacity to determine disability benefits more quickly and efficiently using the Listings.

Myocardial Ischemia
Author: Dennis V. P. Cokkinos
Publisher: Springer Science & Business Media
ISBN: 0387286586
Category : Medical
Languages : en
Pages : 212
Book Description
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. The Editors ACKNOWLEDGEMENTS - Publication of this book was generously supported by Sanofi-Aventis Hellas. - Eikon creative team provided the technical assistance in preparing the manuscripts. - We thank Dr. Bernard Swynghedauw for all his scientific support.
