DIALYSIS THERAPY FOR VOLUME OVERLOAD: A FEASIBLE OPTION TO REDUCE HEART FAILURE HOSPITALIZATIONS IN ADVANCED HEART FAILURE

Abstract

Advanced heart failure (HF) carries a high rate of recurrent HF hospitalizations and a very high mortality rate. Mechanical devices and heart transplantation are limited to a select few. Dialysis may be a good alternative for advanced HF patients with volume overload despite maximal pharmacological therapy.To assess the net clinical outcome of peritoneal dialysis or hemodialysis in patients with advanced HF.We analyzed all advanced HF patients who were referred for dialysis due to volume overload in our institution. Patients were followed for complications, HF hospitalizations, and survival.We assessed 35 patients; 10 (29%) underwent peritoneal dialysis and 25 (71%) underwent hemodialysis; 71% were male; median (interquartile range) age was 74 (67-78) years. Estimated glomerular filtration rate was 20 (13-32) ml/min per 1.73 m2. New York Heart Association functional capacity was III. Median follow-up time was 719 days (interquartile range 658-780). One-year mortality rate was 8/35 (23%) and overall mortality rate was 16/35 (46%). Three patients (9%) died during the first year due to line or peritoneal dialysis related sepsis, and 6 (17%) died during the entire follow-up. The median number of HF hospitalizations was significantly reduced during the year on dialysis compared to the year prior to dialysis (0.0 [0.0-1.0] vs. 2.0 [0.0-3.0], P < 0.001).Dialysis is reasonably safe and significantly reduced HF hospitalization in advanced HF patients. Dialysis could be a good alternative for advanced HF patients with intractable volume overload.
