Fluid overload may occur in patients with myocardial dysfunction and different clinical problems. Myocoardial dysfunction may be a consequence of heart dilatation with reduced contractility, ventricular stiffness with diastolic dysfunction or the consequence of myocardial injury or circulating myocardial depressant factors as seen in sepsis. In all cases, cardiac support can be achieved by the optimization of fluid balance, the reduction in organ edema and the restoration of desirable levels of pre- and afterload. Several reports have shown that myocardial elastance can improve after hemofiltration with restoration of adequate fluid balance. In such conditions, continuous extracorporeal therapy may result in remarkable cardiovascular stability with maintenance of hemodynamic parameters, including mean arterial pressure, heart rate and systemic vascular resistance. Such stability, which is achieved through the slow continuous ultrafiltration and continuous refilling of the intravascular volume from the interstitium, enables the stability of the circulating blood volume and the preservation of organ perfusion. This is also crucial for renal recovery during acute renal failure.
