[Peritoneal dialysis and chronic dobutamine, two experiences contrasted. Possible role and indications in refractory cardiac decompensation].
The number of patients who develop heart failure (HF) is increasing and is expected to increase further in the next decade. Despite the availability of an ever-widening array of pharmacological therapy, patients with end-stage HF have a poor long-term prognosis. Little attention has been paid to alternative non-conventional therapy for these patients. The aim of this non-randomized study was to describe two non-conventional approaches in patients with HF, refractory to conventional medical therapy. The feasibility and long-term efficacy of a continuous ambulatory peritoneal dialysis (CPAD: 20 patients) or dobutamine intermittent infusions (DOB: 11 patients) was analysed: the mean dobutamin dose was 5 gamma/kg/min, and the interval period treatment ranged from 12 hours/day to 12 hours/week.


RESULTS
Both treatments were feasible and non major procedure complications occurred. The 6 and 12 month survival rates were 55% (14/20 patients), 35% (9/20 patients) and 36% (6/11 patients), 18% (3/11 patients) in the CAPD patients and DOB patients, respectively. All patients survived at one year (38% = 12/31 patients) documented a significant functional improvement and quality of life. The conclusions is drawn that the use of CAPD and DOB should be considered in those with refractory HF, in whom medical therapy has failed and in whom home training is considered feasible. Further studies are necessary to define those patients who will benefit from one of these strategies and to confirm these preliminary data.
