Available in PDF, EPUB and Kindle. Book excerpt: The human brain represents about 2% of the body weight, yet it accounts for approximately 20% of aerobic metabolism. This high dependency on energy-consuming processes is mainly caused by the active transport of ions, which is necessary to compensate for the transmembrane ion currents that are part ofthe complex signaling processes in the brain. Ninety-five percent ofthe brain's ATP is derived from mitochondrial oxidative phosphorylation. Since that organ' s storage capacity for oxygen is minimal, any interruption of oxygen delivery to brain cells willlead to changes in membrane excitability and, there fore, to disruption of neuronal signaling within seconds. It seems that mamma lian brain is especially vulnerable to such an interruption, since oxygen deprivation leads to activation of ion channel mechanisms in neurons that impair their communications. Thus, the function of the brain as a coordinator of vital homeostatic reflexes, and complex body reactions to external challenges, depends critically on the rate of oxygen delivery and oxygen consumption. Oxygen delivery depends on two variables described in the Fick relation ship: volume flow rate ofblood and the arterial oxygen content. A reduction in either of these two variables will have serious effects on vital brain func tions. Reduction of arterial blood flow to the brain can be caused by cardiac arrest, shock, carotid occlusion, Of hypotension (global ischemia). Oxygen content is progressively decreased in asphyxia (including drowning).

Download or read book New Concepts in ECG Interpretation written by Alessandro Capucci and published by Springer. This book was released on 2018-11-01 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book elucidates a number of new concepts on P-wave evaluation and QRS depolarization properties, and reports on several repolarization findings never covered in previous ECG books. The content is primarily based on case reports, some of which are compared in order to reveal their ostensibly small but significant differences. The book addresses a significant and lingering gap in ECG interpretation, which is the actual cause of many poor decisions in the diagnostic and therapeutic contexts. Further, the book has an interdisciplinary appeal, and will be of equal interest to professionals and scholars with an interest in cardiology and ECG interpretation.

Book excerpt: Acute lower limb ischaemia is caused by sudden obstruction of an artery due to an embolus or thrombosis.Chronic lower limb ischaemia is a slowly progressing disease process that is usually caused by an obliterating arterial disease.Acute lower limb ischaemia must be diagnosed and the patient immediately referred for further management. Chronic lower limb ischaemia must be diagnosed and its severity (stage) assessed, as the severity of the condition will determine management approach. Mild ischaemia is asymptomatic, but is suggestive of an increased overall cardiovascular risk. Moderate ischaemia causes intermittent claudication which, as such, is a benign but troublesome complaint. Claudication may be treated conservatively, but if the condition threatens the work or functional capacity of the patient, a referral to a vascular surgeon is indicated. Critical ischaemia manifests itself as pain at rest and may lead to a non-healing chronic leg ulcer and eventually to gangrene. Patients with critical limb ischaemia require urgent referral to a vascular surgeon. If limb ischaemia is complicated by an infection, an emergency referral is indicated. If ischaemia is suspected it should be verified with Doppler ultrasonography and pressure measurements. Examination of the patient, see . Prophylaxis against coronary heart disease and ischaemic cerebrovascular disorders should be provided. This has the greatest impact as regards the patient’s prognosis. The arteries of the lower limbs are never the only site of atherosclerosis in a patient with occlusive arterial disease.

Download or read book Myocardial Viability written by Vasken Dilsizian and published by Wiley-Blackwell. This book was released on 2000-02-10 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite remarkable advances in the understanding and management of impaired left ventricular function (LVF) and related coronary disease, the prevalence of heart failure in the U.S. and the resulting death rates have almost tripled in the past 3 decades. New understanding of the relationships between the myocardium and LVF demonstrate a direct correlation between myocardial viability and improved patient survival. Because of this, myocardial viability is now a major investigative area in contemporary cardiology, one that holds significant clinical and prognostic relevance. Authored by physicians of international renown, the book brings together various disciplines affecting myocardial viability, with five main sections providing an introduction and comprehensive review of: basic concepts and mechanisms; vascular biology and cellular physiology; advances in functional imaging; and perfusion, metabolism and cell membrane integrity. New concepts, such as stunning and hibernation, are clarified, and subsequent novel diagnostic and therapeutic strategies are described. New and sophisticated examination techniques are also presented, as well as advances in instrumentation and imaging techniques, which may result in improved use of resources and enhanced efficiency of health care delivery. This monograph will serve as a reference source for those interested in the field of myocardial viability, and hopefully improve understanding between investigators from various disciplines. Clinical cardiologists, physicians, and nurses in the field, as well as radiologists, vascular surgeons, reperfusionists, cellular biologists and physiologists, and students will all find material of interest in this book.

Download or read book Critical Leg Ischaemia written by John A. Dormandy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jean Natali The pathophysiology and management of chronic critical limb -ischaemia (CLI) has always been a problematic area, at least partly because it involves doc tors from a wide range of the traditional medical specialities including vascular surgery, angiology, diabetology, haematology and radiology. The treatment of these patients also varies largely with local circumstances and national traditions. CLI therefore seemed a particularly appropriate subject for a new type of European consensus approach. In 1988 a series of small workshops were held by the European Working Group on Critical Limb Ischaemia to discuss the definition, pathophysiology, in vestigation and management of this condition. The process culminated in a meet ing in Berlin in March, 1989 where 120 specialists from sixteen European countries, representing the basic sciences as well as a spectrum of clinical dis ciplines, met to evolve a Consensus Document on the subject with specific recom mendations. The Document, which is reproduced in the first section of this book, does not of course necessarily represent the unanimous view of all those who participated in its compilation; however it is agreed that it does represent a con sensus or majority view. It was also noted that the comments and recommenda tions in the document should be taken as a whole, and are not intended to dictate the only correct approach to individual treatment.

It is the emergence of huge possibilities in the management of stroke - ultra-early diagnosis, intensive care, surgical and other interventional therapies, thrombolysis, anti-ischemic drugs and prevention of immediate recurrence - which necessiates this timely update.

Download or read book Ischaemic Heart Disease written by K. Fox and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book attempts to focus on the most important clinical aspects of ischaemic heart disease. Clearly, in no way is it supposed to be a comprehensive review of the subject, but it does attempt to address the most important topics for everyday practising clinicians. The question of epidemiology is topical both in the lay and medical press and is, therefore, covered in some detail. It is the editor's opinion that proper understanding of the clinical manifestations of the disease and, therefore, subsequent investigation and treatment are based on a detailed understanding of the pathology and pathophysiology, and as a result these subjects have also been covered in detail. In the last decade there have been considerable advances in our understanding of the mechanisms of angina and also the haemodynamic and metabolic consequences of both angina and myocardial infarction. Again, if appropriate investigations and treatment are to be undertaken, they can only be done with the proper knowledge of the disease being investigated. Finally, the investigation and management of the various mani festations of ischaemic heart disease have been addressed. In the last ten years there has been an explosion in the drugs available for the treatment of ischaemic heart disease and how they should be used has become much more sophisticated. The place of coronary artery surgery has now been rationalized and angioplasty provides an important adjunct to treatment.

Download or read book Prevention and Treatment of Delayed Ischaemic Dysfunction in Patients with Subarachnoid Haemorrhage written by Hans-Jürgen Reulen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last meeting of the European Association of Neurosurgical Societies (Barcelona 7-16 September 1987), a Symposium was devoted to the use of calcium antagonists in cerebral vasospasm. As shown by its title "Prevention and treatment of delayed ischaemic dysfunction in patients with subarachnoid haemorrhage: an update", papers presented at the Symposium covered a broad spectrum from some basic data on pathophysiology of subarachnoid haemorrhage (SAH) and delayed ischaemic dysfunction, to the clinical use of nimodipine, which has been largely documented among calcium inhibitors for its cerebrovascular properties. This supplementum of Acta Neurochirurgica is based upon the papers presented. Some articles, however, have been extended to take into account further results in order to present a broad view of the subject. The Symposium started with two presentations concerning general aspects of SAH: in the first one, B. Voldby reviewed the pathophysiological events following SAH: if modifications of intracranial pressure (ICP) and decrease of cerebral blood flow (CBF) are the primary alterations, metabolic changes (particularly reduction in CMR0 ) 2 contribute rapidly to disturbances of brain circulation. A variety of mechanisms may be responsible for the neurological dysfunction: most of them are directly related to the reduction in cerebral perfusion pressure (CPP) which may result in ischaemia. This fall in CPP (either due to elevation of ICP or reduction of mean arterial blood pressure) is observed under different pathophysiological conditions, discussed in the paper by A. D. Mendelow.

Download or read book Ischaemic Colitis written by J.W. Reeders and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ischemic colitis is becoming increasingly one of the most important conditions involving the colon. This is due to a combination of multiple factors: (1) increasing age of the world population due to improved public health conditions and advances in medicine; (2) diagnostic advances in recognizing the condition; and, (3) education of physicians who suspect the disease in elderly individuals with colonic symptoms. The disease is a great masquerader of other conditions and can be mistaken for ulcerative colitis, Crohn's disease or almost any other inflammatory disease of the large bowel. It can have shallow ulcers, deep ulcers, filiform polyps, and pseudomembrane. It can produce fistulae or toxic megacolon. The thumb printing and other acute findings are not always seen and the site of involvement may be atypical. It is therefore so important to have a book dealing with this condition extensively and in detail. This scholarly presentation based on large clinical experience significantly contributes to the knowledge of this important disease that will assume even more importance as other conditions involving the colon are successfully treated. As physicians, radiologists and even pathologists have difficulty in diagnosing this condition that appears under multiple guises the information contained here should be invaluable. Alexander R. Margulis, M. D. March 1984, San Francisco PREFACE First of all, I would like to congratulate the authors on their successful publication of this monograph with many diagnostic radiographs of new touch taken by the modern technique.
