Download or read book Cardiovascular Remodeling written by Yan Yang and published by Frontiers Media SA. This book was released on 2023-08-25 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the treatment has greatly progressed, the mortality of cardiovascular diseases remains the leading cause of death worldwide. Serious cardiovascular diseases, e.g., myocardial infarction, heart failure, cardiac dysrhythmias, and stroke, are resulted from cardiovascular remodeling secondary to the cardiovascular risk factors, including hypertension, atherosclerosis, cigarette smoking, diabetes mellitus, hyperlipidemia, aging, etc. Cardiac remodeling involves a series of molecular, cellular, and interstitial alterations, which manifest clinically as changes in size, mass, geometry, and function of the heart. In addition, vascular remodeling is an active process of structural alteration involving vascular wall thickening and lumen stenosis due to endothelial injury, vascular smooth muscle cell proliferation, and matrix deposition. This results in atherosclerosis and/or stenosis followed by myocardial infarction, stroke, etc. Thus, studies on the mechanism of cardiovascular remodeling and new therapeutic approaches are important scientifically and clinically. Cardiovascular remodeling is a response of specific cardiovascular cells, including cardiomyocytes, endothelial, smooth muscle cells, and interstitial cells, to noxious hemodynamic, metabolic, and inflammatory stimuli. The remodeling may initially be functional, compensatory, and adaptive, but it progresses to structural alterations that become pathogenic when the damaging stimuli are sustained. The mechanism of cardiovascular remodeling is complex, and recent studies focus on improving and/or reversing the remodeling by clarifying molecular mechanisms and identifying novel therapies. Pharmacological anti-remodeling, RNA-based (long non-coding RNA and microRNA) treatment, cell-based (iPS) cardiac repair, and cell-free exosome approaches have been shown to improve cardiovascular remodeling alongside proangiogenic, pro-survival, proliferative, and immunogenic factors, stimulating endogenous proliferative potential of cardiomyocytes. However, though advanced studies have progressed, the prognosis of the affected patients remains poor. Therefore, understanding novel mechanisms, identifying remodeling biomarkers, and developing new therapeutic drugs and approaches can lead to new therapeutic options for treating patients with cardiovascular diseases.

Download or read book Cardiac Remodeling written by Jerald Sherman and published by Nova Science Publishers. This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cardiovascular diseases are the leading cause of death in almost 40% of patients suffering from end stage renal disease (ESRD). Cardiomyopathy and ischemic heart disease are the most frequent causes of cardiac death. The risk of cardiovascular mortality in dialysis patients is 10 to 20 times greater than the general population, particularly in younger patients, taking into account that the relative risk decreases with age. Left ventricular hypertrophy (LVH) is the most common cardiac abnormality in chronic kidney disease (CKD), and the survival risk ratio in such patients is independent. This book examines the molecular mechanisms, treatments and clinical implication of cardiac remodeling. The first chapter discusses risk factors for cardiovascular disease in patients on continuous ambulatory peritoneal dialysis. The following chapters examine the impacts tropomyosin, vitamin D, and coffee have on cardiac remodeling.
Download or read book Cardiac Remodeling New Insights in Physiological and Pathological Adaptations written by Leonardo Roever and published by Frontiers Media SA. This book was released on 2017-11-15 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effective management of Cardiac remodeling(CR), remains a major challenge. Heart failure remains the leading cause of death in industrialized countries. Yet, despite the enormity of the problem, effective therapeutic interventions remain elusive. In fact, several initially promising agents were found to decrease mortality in patients recovering from myocardial infarction. Cardiac remodeling is defined as molecular and interstitial changes, manifested clinically by changes in size, mass , geometry and function of the heart in response to certain aggression. Initially, ventricular remodeling aims to maintain stable cardiac function in situations of aggression.

Available in PDF, EPUB and Kindle. Book excerpt: This book gathers together contributions from internationally renowned authors in the field of cardiovascular systems and provides crucial insight into the importance of sex- and gender-concepts during the analysis of patient data. This innovative title is the first to offer the elements necessary to consider sex-related properties in both clinical and basic studies regarding the heart and circulation on multiscale levels (i.e. molecular, cellular, electrophysiologically, neuroendocrine, immunoregulatory, organ, allometric, and modeling). Observed differences at (ultra)cellular and organ level are quantified, with focus on clinical relevance and implications for diagnosis and patient management. Since the cardiovascular system is of vital importance for all tissues, Sex-Specific Analysis of Cardiovascular Function is an essential source of information for clinicians, biologists, and biomedical investigators. The wide spectrum of differences described in this book will also act as an eye-opener and serve as a handbook for students, teachers, scientists and practitioners.
Download or read book Exercise Training Regulation of Extracellular Matrix and Remodeling in the Aging Rat Heart written by Hyo Bum Kwak and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Aging is characterized by a progressive impairment of cardiac structure and function. The cardiac remodeling involves loss of cardiac myocytes, reactive hypertrophy of the remaining cells, and increased extracellular matrix (ECM) and fibrosis in the aging heart. In contrast, exercise training not only improves cardiac function, but also reduces the risk of heart disease. However, the ability of exercise training to modulate ECM and remodeling in the aging heart remains unknown. Therefore, the purpose of this study was to determine the effects of exercise training on ECM remodeling in the aging heart. We hypothesized that (1) exercise training would attenuate age-related changes in left ventricle morphology including extramyocyte space and collagen contents, and (2) exercise training would ameliorate age-induced changes in ECM-related factors including MMPs, TIMPs, TNF-[alpha], TGF-[beta]1, and [alpha]-SMA in the heart. Three and 31 month old Fischer 344 x Brown Norway F1 hybrid rats were assigned to four groups: young sedentary (YS), young exercise-trained (YE), old sedentary (OS), and old exercise-trained (OE). Exercise training groups walked briskly on a treadmill for 45 min/day (12° incline) at 20m/min (young) or 10 m/min (old), 5 d/wk for 12 wk. We found that endurance exercise training might ameliorate the ageinduced increase in extramyocyte space and collagen contents of the left ventricle. Exercise training might protect against age-induced fibrosis by increasing MMP-2, MMP-14 in the soluble fraction and MMP-1, MMP-3, MMP-14 in the insoluble fraction of old rat hearts. Conversely, exercise training might reduce the fibrosis by decreasing TIMP-1 in the soluble fraction of old rat hearts. Further, exercise training reduced potential upstream pro-fibrotic mediators including TNF-[alpha] and TGF-[beta]1 in the aging rat hearts. These results are the first to demonstrate that exercise training has a protective effect against age-induced extracellular collagen matrix remodeling in the aging heart, associated with increased MMP-1, -2, -3, -14 and decreased TIMP-1, TNF-[alpha], and TGF- [beta]1.
Download or read book The Role of Autophagy in Cardiac Aging and Aging associated Chronic Diseases written by Shuyi Wang and published by . This book was released on 2019 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aging is becoming an escalating issue in the world as human life expectancy continues to rise. Advanced aging imposes a cadre of chronic disease including cardiovascular diseases. The aging heart displays unfavorable changes in both geometry and function including increased left ventricular (LV) mass, reduced cardiac reserve capacity, myocardial fibrosis and increased risk of arrhythmia, contributing to poor exercise capacitance (effort intolerance) and frailty in the elderly. In addition, aging also increases the risk of many chronic diseases that jeopardize the cardiovascular function and quality of life in the elderly. With progressive aging, several pathological conditions including obesity, type II diabetes mellitus, Alzheimer’s disease and cancer are on the horizon. For example, obesity has been considered as a trigger for premature aging, leading to pathological cardiac remodeling and compromised ventricular function. Alzheimer’s disease is a neurodegenerative disease featured by accumulation of amyloid plaque and neurofibrillary tangles. Alzheimer’s disease may provoke cardiovascular dysfunction impairment of diastolic function. Over the past decades intense effort has been made towards understanding the mechanistic framework behind aging, obesity and Alzheimer’s disease in the pathogenesis of cardiovascular anomalies. An emerging role of dysregulated autophagy, a conservative homeostatic process for cellular quality control by way of disposal and recycling of cellular components, has surfaced in cardiac anomalies under all these pathological settings. To this end, this dissertation research will focus on the underlying mechanism of cardiac remodeling and contractile dysfunction during the normal aging process, as well as aging-associated conditions such as obesity and Alzheimer’s disease. The major findings from my work revealed that (1): Ablation of TLR4 restores autophagy level through the regulation of NCoR1/HDAC and improves heart function in aging; (2): Knocking out of Akt and AMPK facilitates premature cardiac aging in a joint manner; (3): Mitochondrial aldehyde dehydrogenase (ALDH2) overexpression protects obese heart through SUV39H1-Sirt1 signaling; and (4): Melatonin protects Alzheimer’s disease-associated heart dysfunction through cGAS-STING regulated autophagy in the presence of ALDH2.

Download or read book Epigenetics of Aging written by Trygve O. Tollefsbol and published by Springer Science & Business Media. This book was released on 2009-11-11 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies have indicated that epigenetic processes may play a major role in both cellular and organismal aging. These epigenetic processes include not only DNA methylation and histone modifications, but also extend to many other epigenetic mediators such as the polycomb group proteins, chromosomal position effects, and noncoding RNA. The topics of this book range from fundamental changes in DNA methylation in aging to the most recent research on intervention into epigenetic modifications to modulate the aging process. The major topics of epigenetics and aging covered in this book are: 1) DNA methylation and histone modifications in aging; 2) Other epigenetic processes and aging; 3) Impact of epigenetics on aging; 4) Epigenetics of age-related diseases; 5) Epigenetic interventions and aging: and 6) Future directions in epigenetic aging research. The most studied of epigenetic processes, DNA methylation, has been associated with cellular aging and aging of organisms for many years. It is now apparent that both global and gene-specific alterations occur not only in DNA methylation during aging, but also in several histone alterations. Many epigenetic alterations can have an impact on aging processes such as stem cell aging, control of telomerase, modifications of telomeres, and epigenetic drift can impact the aging process as evident in the recent studies of aging monozygotic twins. Numerous age-related diseases are affected by epigenetic mechanisms. For example, recent studies have shown that DNA methylation is altered in Alzheimer’s disease and autoimmunity. Other prevalent diseases that have been associated with age-related epigenetic changes include cancer and diabetes. Paternal age and epigenetic changes appear to have an effect on schizophrenia and epigenetic silencing has been associated with several of the progeroid syndromes of premature aging. Moreover, the impact of dietary or drug intervention into epigenetic processes as they affect normal aging or age-related diseases is becoming increasingly feasible.
Download or read book Advances in Geroscience written by Felipe Sierra and published by Springer. This book was released on 2015-11-10 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the first comprehensive overview of a new scientific discipline termed Geroscience. Geroscience examines the molecular and cellular mechanisms that might explain why aging is the main risk factor for most chronic diseases affecting the elderly population. Over the past few decades, researchers have made impressive progress in understanding the genetics, biology and physiology of aging. This book presents vital research that can help readers to better understand how aging is a critical malleable risk factor in most chronic diseases, which, in turn, could lead to interventions that can help increase a healthy lifespan, or ‘healthspan.’ The book begins with an analysis of the Geroscience hypothesis, as well as the epidemiological underpinnings that define aging as a candidate main risk factor for most chronic diseases. Next, each chapter focuses on one particular disease, or group of diseases, with an emphasis on how basic molecular and cellular biology might explain why aging is a major risk factor for it. Coverage in the book includes: cancer, cardiovascular disease, dementias, stroke, Parkinson's and Alzheimer’s diseases, osteoporosis, arthritis, diabetes asthma, emphysema, kidney disease, vision impairment, and AIDS/HIV. It finishes with a chapter on pain in the elderly and an overview of future steps needed to bring the newly acquired knowledge into the clinic and the public at large.
