Purpose: We evaluated clinical outcomes in patients with type 2 cardiorenal syndrome who were treated with peritoneal dialysis (PD) or hemodialysis (HD).
Methods: A retrospective database of PD or HD patients with type 2 cardiorenal syndrome from January 1, 2002 to December 31, 2010 was established. We evaluated the mean survival on dialysis, days of hospitalizations and NYHA class changes.
Results: Thirty-two patients with mean age at the start of dialysis of 68.4±10.8 years had mean survival on dialysis of 20.5±14.4 months (median survival 17.8 months). Survival after starting dialysis is highly variable, but long term survival was proved possible. The days of hospitalization for cardiovascular causes were reduced (25.1±17.7, predialysis vs. 9.5±32.8 days/patient/month, postdialysis, p= 0.013). All patients showed improvement in NYHA functional class. Kidney function stabilized, while significant improvement in hemoglobin (+16.5%, p<0.001) were achieved.
Conclusion: After starting dialysis for Type 2 cardiorenal syndrome, the chances of hospitalization for cardiovascular causes were reduced for all patients. Survival on dialysis in these patients was highly variable.
