Objectives • To assess the prognostic value of the urea/creatinine ratio (UCR) in patients admitted with heart failure (HF) • To assess the impact of the UCR on efficacy of loop diuretic uptitration in HF
Methods • Cohort study in single tertiary care center(Ziekenhuis Oost-Limburg, Genk, Belgium) • Consecutive patients admitted with a primary diagnosis of HF (January, 2009 – March, 2011) • Loop diuretic uptitration: increase of maintenance dose at discharge compared to admission • End-point: freedom from all-cause mortality or HF readmission
ResultsSTUDY FLOWCHART • Follow-up: 22 ± 10 months • 54 patients died (17%) • 91 patients readmitted for HF (29%) • 194 patients with event-free survival (61%)
ResultsUREA/CREATININE RATIO Freedom from all-cause mortality or HF readmission Adjusted HR (95% CI) for 1 SD increase in UCR = 1.30 (1.05 – 1.62) P-value = 0.001
ResultsLOOP DIURETIC UPTITRATION Freedom from all-cause mortality or HF readmission Loopdiureticuptitration Loopdiureticuptitration P-value = 0.041 P-value = 0.559 HR (95% CI) for uptitration = 1.61 (1.01 – 2.57) HR (95% CI) for uptitration = 1.07 (0.61 – 1.89)
Conclusions • The UCR is a strong and independent predictor of all-cause mortality and readmissions in hospitalized HF patients • High UCR, as a surrogate for neurohumoral activation, characterizes a vulnerable population that demonstrates adverse outcome with loop diuretic uptitration Alternatives for decongestive therapy?
