The vast majority of acute heart failure syndrome (AHFS) hospitalizations are related to clinical congestion, rather than to a low cardiac output state. Patients develop hemodynamic congestion (high left ventricular filling pressure) several days to weeks before the onset of clinical symptoms and signs. Congestion is an important predictor of ...

BACKGROUND: The traditional medical treatment of acute heart failure (AHF) has remained unchanged for many years. It has been based on oxygen supplementation and mechanical ventilatory support as well as the administration of morphine, diuretics, nitrates and inotropic agents. In 2005 the European Society of Cardiology (ESC) published new guidelines ...

Chronic heart failure (CHF) is a common and disabling condition with an incidence and prevalence that increase sharply with age. The median age of presentation of new heart failure cases is > 75 years. Effective treatments, including beta-adrenoceptor antagonists, have been proven in randomised, controlled trials. The average age in ...

Mild hyponatremia is encountered frequently in patients hospitalized for worsening heart failure. Admission plasma sodium concentration appears to be an independent predictor of increased mortality after discharge and rehospitalization. Recent studies have suggested that correction of hyponatremia may be associated with improved survival. This hypothesis is currently being studied in ...
