[Treatment of refractory heart failure with different dialysis technics].
The efficacy of the dialysis in the heart failure non responsive to the traditional methods is well known. In our study we have evaluated the effects of three different dialytic methods (UFI: ultrafiltration isolate; HF: hemofiltration; CAVH: continuous arteriovenous hemofiltration). These methods are used to cause a good depletion in the patients with intractable heart failure following from ischaemic valvular or primitive cardiomiopathy. We have treated 18 patients (6 for each method) and the patients with organic or functional renal disease were treated with the methods (HF and CAVH) that have depletive and depurative effects. Each of these methods is capable, without important differences, of achieving the following aim: the hydro-sodium depletion, the correction of the haemodynamic alteration and the re-establishment of the response to the traditional medical treatment. Using the hemofiltration and continuous arteriovenous hemofiltration, both soft methods, we have obtained values of dehydratation, absolute and for each session, higher than isolated ultrafiltration. The follow-up has not pointed out differences, of both prognosis and survival among patients treated with the three methods studied, whose effects are always only temporary; only the heart transplantation or the valvular correction, by operating in a very important way on the basal cardiopathy, is the resolutive event.
