At this time, the concepts of"forward failure" and "backward failure" were proposed, where the assumption was that an insult to the heart would impair its ability to either "pump" blood to the kidney (therefore interfering with the renal excretion of sodium and water), or its ability to ...

Congestive heart failure has been considered a syndrome characterized by pulmonary and/or systemic venous congestion accompanied by a low cardiac output. Recently, however, it has become clear that a broad definition of this sort has confused understandi

The overall approach to heart failure includes defining the etiology, identifying precipitant factors, and assessing the severity of myocardial dysfunction and clinical symptoms.
