Available in PDF, EPUB and Kindle. Book excerpt: Physiologists have long been interested in the interaction, or coupling, between the heart and the vasculature. The early literature consists mainly of phenomenological descriptions of cardiac alterations resulting from specific interventions in the vasculature. Hundreds of studies, for example, describe functional aspects of hypertrophied myocardium associated with the excessive vascular loading produced by various types of experimental hypertension. Recently, the concepts of ventricular/vascular interaction have found important clinical application. The widespread use of vaso dilators and of intraaortic counterpUlsation balloons for unloading an ov erburdened, diseased heart is a prime example. Despite the interest in this field, until as recently as 20 years ago we were not able to describe ventricular or vascular function in a framework suitable for quantitatively expressing the interaction between these two complex systems. Three major developments-description of ventricular function in terms of both the time-varying elastance and the pump function graph and quantification of vascular function in terms of impedance have changed this. These functional descriptions now enable systems en gineers, bioengineers, physiologists, and clinicians to address very specific quantitative aspects of ventricular/vascular interaction and have resulted in a flurry of papers and symposia devoted to this subject.

Available in PDF, EPUB and Kindle. Book excerpt: Contractility describes the relative ability of the heart to eject a stroke volume (SV) at a given prevailing afterload (arterial pressure) and preload (end-diastolic volume; EDV). Various measures of contractility are related to the fraction as the SV/EDV or the ejection fraction, and the dynamics of ejection as determined from maximum pressure rise in the ventricles or arteries or from aortic flow velocities determined by echocardiography. At the cellular level, the ultimate determinant of contractility is the relative tension generation and shortening capability of the molecular motors (myosin cross-bridges) of the sarcomeres as determined by the rates and extent of Ca activation, the turnover kinetics of the cross-bridges, and the relative Ca responsiveness of the sarcomeres. Engagement of the regulatory signaling cascades controlling contractility occurs with occupancy and signal transduction by receptors for neurohumors of the autonomic nervous system as well as growth and stress signaling pathways. Contractility is also determined by the prevailing conditions of pH, temperature, and redox state. Short-term control of contractility is fully expressed during exercise. In long-term responses to stresses on the heart, contractility is modified by cellular remodeling and altered signaling that may compensate for a time but which ultimately may fail, leading to disorders.

Available in PDF, EPUB and Kindle. Book excerpt: The increasing mean age of the population in developed countries has turned out to be an economic and social problem. Cardiovascular disease has long been considered to be age related in terms of their onset and progression. As such, we can say that the increase in life expectancy goes in parallel with increased incidence of cardiovascular disease. With age, a number of changes occur in the vasculature altering the homeostasis of the irrigated organs promoting target organ damage. While different adaptive mechanisms to protect vessels against mild stress have been described, the aging process induces a progressive failure of protective mechanisms, leading to vascular changes and higher susceptibility to cardiovascular diseases. Indeed, vascular aging is exacerbated by coexisting cardiovascular risk factors, such as hypertension, metabolic syndrome and diabetes. Compelling evidence indicates that diminished endothelial relaxation and increase, decrease, or no change in contractile responses to several agonists is associated with aging. There is an increase of vasoconstrictor factors expression and a decrease of vasodilators. Morphologic changes include lumen diameter enlargement, wall thickening and alterations of matrix substances as increased collagen or decreased elastin deposition, ultimately leading to greater arterial stiffening (reduced compliance). Importantly, arterial stiffness is an independent predictor of cardiovascular morbidity and mortality. Cellular and molecular mechanisms have also been documented. Senescence at the cellular level involves alterations in Ca2+ signaling and down regulation of anti-aging proteins. Both endothelial and smooth muscle cells change their number, morphology, function and their regenerative ability. Aging is also associated with a gradual loss of antioxidant defense mechanisms, a proinflammatory shift in the cytokine expression profile and a production of reactive oxygen species such as superoxide (O2-) that promotes the breakdown of nitric oxide. Nitric oxide and O2- interact to form peroxynitrite known to nitrosylate proteins affecting their physiological function. However, vascular wall proteins may also suffer from other potentially deleterious modifications as glycation (Maillard reaction) and glyco-oxidative reactions with increasing age, which could be linked to the age-associated changes in vascular function. Various strategies have shown benefit in preventing, delaying or attenuating vascular aging. For instance, a healthy lifestyle including low fat diet and/or exercise have a favorable effect. Nevertheless, it yet remains to be fully demonstrated whether vascular aging can be pharmacologically prevented. This Research Topic is intended to bring together research efforts to understand the causes and consequences of vascular aging and propose new therapeutic strategies for the management of vascular senescence.

Download or read book Recent Progress in Failing Heart Syndrome written by Shigetake Sasayama and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heart failure is a syndrome caused by a heart dysfunction that leads to insuf ficient blood in the peripheral tissues for their metabolic demands. This syn drome still remains an obscure clinical entity and even its definition is disputed. It has become increasingly apparent that heart failure may relate not only to cardiac dysfunction but also to other physiological alterations involved in the maintenance of circulatory homeostasis. In 1988, the Japanese Circulation Society organized a three-year project for research on heart failure. The research group consisted of ten investigators, all relatively young but well recognized internationally for their research accomplishments. This book represents a compilation of the achievements by this group during the past three years which have led to new insights into the pathophysiologic mechanisms of heart failure, and diagnosis, evaluation and treatment of this syndrome. Contents include research into the cellular biology of congestive heart failure, and a framework of pressure-volume relationships enabling assessment of ventricular contraction energetics or coupling of ventricular properties and arterial load. This conceptual framework is of vital significance, particularly when we consider the failing heart as an energy-depleted state. An understanding of the neuroendocrine responses to explain the pathophy siology of congestive heart failure is perhaps the most important advance, and has led to new developments in therapy. This book also includes an analysis of mechanical factors, including both regional, and global ventricular functions, and this is related to the under standing of the pathophysiology of congestive heart failure.

The skeptic would argue that this renewed interest resulted from an exhaustion be incomplete without at least cursory reference we have of clinically-related observations that could be to the pulmonary circulation.
