The sympathetic nervous system in heart failure physiology, pathophysiology, and clinical implications.

Nov 2009 Heart failure is a syndrome characterized initially by left ventricular dysfunction that triggers countermeasures aimed to restore cardiac output. These responses are compensatory at first but eventually become part of the disease process itself ... Read more...

Recommendation of low-salt diet and short-term outcomes in heart failure with preserved systolic function.

30 Oct 2009 BACKGROUND: Dietary sodium indiscretion frequently contributes to hospitalizations in elderly heart failure patients. Animal models suggest an important role for dietary sodium intake in the pathophysiology of heart failure with preserved systolic ... Read more...

A hemodynamic profile for consciousness during cardiopulmonary resuscitation.

30 Oct 2009 We report the quantification of a hemodynamic profile sufficient to support consciousness during cardiopulmonary resuscitation. A 62-yr-old man experienced cardiac arrest while being evaluated for heart failure after heart transplantation. During ... Read more...

Technical information about 'Heart Failure'

Definition: A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
