Abstract

OBJECTIVES: Over the past decade, the number of patients on dialysis and with cardiovascular diseases has steadily increased. This retrospective analysis compares the postoperative mortality after cardiac surgery between patients on hemodialysis and peritoneal dialysis.

METHODS: Between 1998 and 2015, 136 patients with end-stage renal disease initiating dialysis more than one month before surgery underwent cardiac surgery. Demographics, preoperative hemodynamic and biochemical data were collected from the patient records. Vital status and date of death was retrieved from a national register.

RESULTS: Hemodialysis was undertaken in 73% and peritoneal dialysis in 22% of patients aged 59.7 ± 12.9 years, mean EuroSCORE 8.6% ± 3.5. Isolated coronary artery bypass graft was performed in 46%, isolated valve procedure in 29% and combined procedures in 24% with no significant statistical difference between groups. The 30-day mortality was 14% for hemodialysis patients and 3% for peritoneal dialysis patients (p = .056). One-year and 5-year mortality were, 30% and 59% in the hemodialysis group, 30% and 57% in the peritoneal dialysis group (p = .975, p = .852). Independent predictors of total mortality were age (p = .001), diabetes (p = .017) and active endocarditis (p = .012).

CONCLUSION: No statistically significant difference in mortality was found between patients in hemo- or peritoneal dialysis. However, we observed that patients with end-stage renal disease on dialysis have two times higher mortality rate than estimated by EuroSCORE.
