The aim of the study was to evaluate the daily use of hemofiltration in patients with anuria and heart failure IV NYHA, and not reacting to pharmacological therapy. Patients were submitted to daily hemofiltration therapy considering: the dry weight, BP, pO2, creatininemia, natriemia, kaliemia, and magnesiemia. Every month an echocardiogram and an ECG were done. Two patients passed from IV to III class NYHA, with a reduction in the telediastolic diameter and improvement in the ejection fraction and in the cardiothoracic index. In NYHA IV patients, it was possible to obtain a very good improvement in the clinical situation, echocardiographic parameters and survival with daily hemofiltration.
