Prognostic value of the combination of uric acid and NT-proBNP in patients with chronic heart failure

Hyperuricemia is associated with poor outcomes in chronic heart failure (HF). We aimed to evaluate whether uric acid (UA) alone or in combination with N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a good predictor of all-cause mortality, HF hospitalization, and the composite endpoint of HF hospitalization or all-cause mortality in chronic HF. UA and NT-proBNP levels were evaluated retrospectively in 861 chronic HF patients with a left ventricular ejection fraction of ≤50%. The patients were compared by dividing them into 4 groups according to the cut-off values of UA and NT-proBNP. Serum UA concentrations were ≥ 7.0 mg/dL in 46.5% of the subjects. With a median follow-up of 30 months, 201 (23.3%) patients died and 308 (35.8%) patients were hospitalized during the study. The all-cause mortality rate was higher in the hyperuricemic group than that of the normouricemic group (p
