Book Description
This book summarizes present knowledge of different mechanisms involved in the development of positive and negative consequences of cardiac adaptation. Particular attention is paid to the still underestimated adaptive cardiac responses during development, to adaptation to the frequently occurring pressure and volume overload as well as to cardiac changes, induced by enduring exercise and chronic hypoxia. Cardiac Adaptations will be of great value to cardiovascular investigators, who will find this book highly useful in their cardiovascular studies for finding solutions in diverse pathological conditions; it will also appeal to students, fellows, scientists, and clinicians interested in cardiovascular abnormalities.

Book Description
Cardiac hypertrophy and accompanying phenomena have received increasing attention in recent years - particularly in the basic sciences. The present volume contains the proceedings of the Erwin RIESCH SYMPOSIUM on "CARDIAC ADAPTATION TO HEMODYNAMIC OVERLOAD, TRAINING AND STRESS" held in Tiibingen on Sep tember 19-22, 1982. In addition to the topics of the previous symposia (1976 and 1979) concerned with problems of cardiac hypertrophy, the scope of this sequel meeting has been expanded to include related fields. The intention was to consider numerous related features and problems of chronic reactions of the heart (and vascular system) to abnormal hemodynamic loading, as well as alterations due to maturation, aging, training, neuroendocrine status and stress. Special attention has been paid to cardiac reactions at the level of contractile proteins. The results are considered primarily in light of long-term adaptation of the heart. Of course, research at the forefront of current knowledge need not always lead to congruent conclusions. Neither can the individual contributions always agree with the viewpoint of the editors. However, the broad array of individual approaches employed by biochemists, biolo gists, pathologists, physiologists, pharmacologists and clinical cardio logists will certainly help to provide a more balanced interpretation of the results in individual fields, stimulate reexamination of established con cepts and provide direction for future research.

Book Description
Hypertensive disorders are among the most common medical complications of pregnancy, with an incidence of approximately 6-10%. This spectrum of conditions includes essential hypertension, pre-eclampsia and HELLP syndrome. For patients with pre-existing hypertension, management ideally commences prior to conception, and continues through pregnancy to the postnatal period. This book provides information on the evidence-based management of women with hypertension throughout pregnancy, supported by important background information on the etiology, risk-factors and pathophysiology of these disorders. Illustrated with accompanying algorithms, tables and lists for quick reference on diagnostic criteria, drugs and side-effects, this book will help clinicians rapidly gain access to the information they need to care for these patients. This will to be of interest to all grades of obstetric trainees as well as specialists, obstetric anesthetists and anesthetic trainees, midwives and maternal-fetal physicians.

Book Description
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.

Book Description
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.

Book Description
Research centering on blood flow in the heart continues to hold an important position, especially since a better understanding of the subject may help reduce the incidence of coronary arterial disease and heart attacks. This book summarizes recent advances in the field; it is the product of fruitful cooperation among international scientists who met in Japan in May, 1990 to discuss the regulation of coronary blood flow.

Book Description
This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.
