Heart failure (HF) is a highly complex clinical syndrome, culminating from a diversity of environmental and genetic etiologies that compromise pump function, ultimately resulting in insufficient blood flow to the body. Despite the initial disease in the heart, the pathophysiology of HF evolves to ...
- Definition & Related Vocabulary from Chapter 16/ Lesson 6 10K Kidney failure occurs when the kidneys become unable to remove wastes from the body's bloodstream. Explore the definition and related vocabulary of renal failure. Learn about acute and chronic renal failure, uremia, and azotemia to ...
Heart failure is defined as a complex clinical syndrome that occurs because of a structural or functional impairment of the heart muscle, which impairs its ability to either pump blood to the other organs of the body or to do so without increased pressure in the different heart chambers.We typ...
Heart failure is a clinical syndrome that can be caused by a variety of etiologies and mechanisms. The most common haemodynamic mechanism responsible for heart failure in horses is volume overload caused by valvular regurgitation or by a left to right shunt. However, myocardial systolic failure (...
Basic mechanisms of chronic heart failure are reviewed. A central theme that cuts all the way through this review is that chronic heart failure is a problem of failing complexity, rather than a problem of the failure of a single unit (e.g., cell type) or processes (e.g., contractility)...
analysis, 2 had no increase in heart rate on exercise, 1 was found to have evidence of ischemia on cardiopulmonary exercise test, 1 had normal maximum oxygen consumption (VO2max) on exercise, and 1 had entirely normal echocardiography and symptoms were thought to be related to atrial ...
Heart failure develops when the heart, via an abnormality of cardiac function (detectable or not), fails to pump blood at a rate commensurate with the requirements of the metabolizing tissues or is able to do so only with an elevated diastolic filling pressure. See the image below. ...

As both systolic and diastolic heart failure are strongly related from a pathophysiologic point of view, strategies to improve prognosis should not essentially differ. 展开 DOI: 10.1007/978-1-84628-715-2_56 年份: 2007 收藏 引用 批量引用 报错 分享 ...
Heart failure is a clinical syndrome characterized by exertional fatigue, exertional dyspnea, or both related to cardiac dysfunction. 1 It is commonly accompanied by circulatory congestion manifested by edema in the lungs or extremities and by ventricular arrhythmias (Fig. 62.1). Heart failure may ...
