Introduction The prognosis of patients with acute kidney injury (AKI) caused by type 1 cardiorenal syndrome (CRS) requiring continuous renal replacement therapy (CRRT) is unclear. We investigated the in-hospital mortality and prognostic factors in these patients. Methods We retrospectively identified 154 consecutive adult patients who received CRRT for AKI caused by type 1 CRS between January 1, 2013, and December 31, 2019. We excluded patients who underwent cardiovascular surgery and those with chronic kidney disease stage 5. The primary outcome was in-hospital mortality. Cox proportional hazards analysis was performed to analyze independent predictors of in-hospital mortality. Results The median age of patients at admission was 74.0 years (interquartile range: 63.0-80.0); 70.8% were male. The in-hospital mortality rate was 68.2%. Age ≥80 years (hazard ratio, 1.87; 95% confidence interval [CI], 1.21-2.87; P=0.004); previous hospitalization for acute heart failure (hazard ratio, 1.67; 95% CI, 1.13-2.46; P=0.01), vasopressor or inotrope use (hazard ratio, 5.88; 95% CI, 1.43 - 24.1; P=0.014), and mechanical ventilation (hazard ratio, 2.24; 95% CI, 1.46 -3.45; P<0.001) at CRRT initiation were associated with in-hospital mortality. Discussion/Conclusion In our single-center study, the use of CRRT for AKI due to type 1 CRS was associated with high in-hospital mortality. .
