Available in PDF, EPUB and Kindle. Book excerpt: Heart disease including ischemic heart disease is the highest contributor to death and morbidity in the western world. The studies presented were conducted to determine possible pathways of protection of the heart against ischemia/reperfusion. We employed adenovirus mediated over-expression of Methionine sulfoxide reductase A (MsrA) in primary neonatal rat cardiac myocytes to determine the effect of this enzyme in protecting against hypoxia/reoxygenation. Cells transfected with MsrA encoding adenovirus and subjected to hypoxia/reoxygenation exhibited a 45% decrease in apoptosis as compared to controls. Likewise total cell death as determined by levels of Lactate Dehydrogenase (LDH) release was dramatically decreased by MsrA overexpression. The initial hypothesis that led to our testing sulindac was based on the fact that the S epimer of sulindac was a substrate for MsrA and that this compound might function as a catalytic anti-oxidant based on a reaction cycle that involved reduction to sulindac sulfide followed by oxidation back to sulindac. To test this we examined the protective effect of sulindac in hypoxia re-oxygenation in both cardiac myocytes in culture and using a Langendorff model of myocardial ischemia. Using this model of myocardial ischemia we showed that pre-incubation of hearts with sulindac, or the S and R epimers of sulindac resulted in protection against cell death. We present several lines of evidence that the protective effect of sulindac is not dependent on the Msr enzyme system nor does it involve the well established role of sulindac as a Cyclooxygenase (COX) inhibitor. Numerous signaling pathways have been implicated in myocardial protective mechanisms, many of which require fluctuations in ROS levels as initiators or mediators. Sulindac shows very good potential as a preconditioning agent that could induce tissue protection against oxidative damage. Blocking of preconditioning pathways by administration of the PKC blocker chelerythrine abrogated the ischemic protection afforded by sulindac. Secondly, an end-effector of preconditioning, inducible nitric oxide synthase (iNOS), was found to be induced by greater than 5 fold after 48 h prior feeding sulindac.

Available in PDF, EPUB and Kindle. Book excerpt: How to protect against ischemia/reperfusion damage is one of the most urgent problems in medicine. It is known that ischemic damage can be attenuated by improving the oxygen balance of the ischemic heart, but the damage-producing mechanism is not yet fully understood. This book provides the latest information on the pathophysiology of ischemia/reperfusion damage and presents new ideas for more effective methods for protection. In the first two sections, the roles of such factors as various ions and phospholipids that modulate ischemia/reperfusion damage are explored, providing a clear and updated explanation of the mechanisms involved. In the third section, the myocardial and vascular remodeling procedure in hearts that have undergone ischemia/reperfusion is explained in terms of signal transduction, enabling a new understanding of the remodeling process. In the final section, a new approach to protection against ischemia/reperfusion damage is presented.

Download or read book Adaptive Protection of the Heart written by Felix Z. Meerson and published by CRC Press. This book was released on 2019-08-15 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published in 1991: This book explores the possibilities of protecting the heart against stress and ischemia through adaptation to intermittent hypoxia or to mild, nondamaging stress exposure. These possibilities are based on studies that show an increase in the potency and efficiency of stress-limiting systems when subjected to repeated stress actions, adaptation to high altitude hypoxia, or adaptation to increased physical loads. Any stress reaction is coupled with an activation of central and local stress-limiting systems, such as GABA-ergic, opioidergic, and serotonergic systems in the brain, as well as antioxidants, prostaglandins, and adenosine in executory organs. The book also presents the use of metabolites of stress-limiting systems rather than adaptation as a means to prevent cardiac arrythmias. It also discusses genetically determined deficiencies of stress-limiting systems and their role in the etiology of stress-induced diseases. Cardiologists and researchers studying stress and its effect on cardiovascular systems will find this book extremely useful.

Download or read book Coronary Microvascular Dysfunction written by Filippo Crea and published by Springer Science & Business Media. This book was released on 2013-08-15 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Interactive Phenomena in the Cardiac System written by S. Sideman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cardiac system represents one of the most exciting challenges to human ingenuity. Critical to our survival, it consists of a tantalizing array of interacting phenomena, from ionic transport, membrane channels and receptors through cellular metabolism, energy production to fiber mechanics, microcirculation, electrical activation to the global, clinically observed, function, which is measured by pressure, volume, coronary flow, heart rate, shape changes and responds to imposed loads and pharmaceutical challenges. It is a complex interdisciplinary system requiring the joint efforts of the life sciences, the exact sciences, engineering and technology to understand and control the pathologies involved. The Henry Goldberg Workshops were set up to address these multivariable, multidisciplinary challenges. Briefly, our goals are: To encourage international cooperation and foster interdisciplinary interaction between scientists from the different areas of cardiology; to relate microscale cellular phenomena to the global, clinically manifested cardiac function; to relate conceptual modeling and quantitative analysis to experimental and clinical data; to gain an integrated view of the various interacting parameters, identify missing links, catalyze new questions, and lead to better understanding of the cardiac system. The outstanding success of past workshops has encouraged their continuation. The first Henry Goldberg Workshop, held in Haifa in 1984, introduced the concept of interaction between 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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This book bridges the gap between fundamental and translational research in the area of heart disease. It describes a multidisciplinary approach, and demonstrates biochemical mechanisms associated with dysregulation of redox signaling, which leads heart disease. Presenting recent studies on improved forms of ROS scavenging enzymes; specific inhibitors for different ROS generating enzymes; and oxidant induced signaling pathways and their antagonists that allow subtle modulation of redox signaling, it also discusses the spatial and temporal aspects of oxidative stress in the cardiovascular system, which are of vital importance in developing better strategies for treating heart disease. Each chapter offers researchers valuable insights into identifying targets for drug development for different types of heart disease.

Download or read book Platelets in Cardiovascular Disease written by Deepak L. Bhatt and published by Imperial College Press. This book was released on 2008 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Platelets in Cardiovascular Disease provides an in-depth and current coverage of relevant platelet biology and antiplatelet therapy that is in clinical use today and potentially for the future. The book provides a succinct overview of the critical role of platelets in cardiovascular medicine. Cardiovascular disease is the leading cause of mortality worldwide, and recent research has found that the platelet is central to the genesis of heart attacks and stroke as well as many of the complications of angioplasty and bypass surgery. An explosion of knowledge of the biology of platelets has established their important role in the formation of blood clots and, perhaps more intriguingly, their role as inflammatory cells. This growth in information has been paralleled by the development of several drugs that can interfere with platelet action and thereby improve patient outcomes. Indeed, several antiplatelet drugs already in development may ultimately lead to marked advances in both the treatment and prevention of cardiovascular disease. Drawing upon a panel of international experts, Platelets in Cardiovascular Disease delivers a concise yet thorough review of the major developments in antiplatelet therapy. Practicing clinicians as well as those involved in the development of new antithrombotic therapies will find the book interesting and useful. Sample Chapter(s).

Download or read book Ischaemia Reperfusion Injury written by Pierce A. Grace and published by Wiley-Blackwell. This book was released on 1999-02-04 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ischaemia-Reperfusion Injury is concerned with the consequences of interrupting and restoring blood flow to tissues. Many common clinical conditions are caused by interruption of blood flow to tissues (eg, ischaemic heart disease, peripheral vascular disease, stroke); blood flow is also interrupted deliberately in many surgical procedures (eg, cardiac surgery, arterial surgery, transplant surgery, limb surgery with tourniquet). In treating such conditions or after performing such operations the aim of the clinician is to restore the blood supply to the ischaemic tissue. Paradoxically, restoration of blood flow to ischaemic tissues can lead to further tissue damage with the potential for severe local and systemic injury. This book focuses on the clinical, pathological and biochemical processes involved in ischaemia-reperfusion injury and gives an overview of the strategies that may be adopted to mitigate or prevent such injury. This book will be of interest to both clinicians and scientists who have to deal with or have interest in this difficult but important problem.
