Özet

Objective: 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. Methods: 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. Results: 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 < 0.001). A multivariate Cox regression model revealed that UA and NT-proBNP were independent predictors of all-cause mortality (HR: 1.105, 95% CI: 1.019-1.198, p = 0.016 and HR: 3.743, CI: 2.647-5.292, p < 0.001, respectively). Patients were divided into 4 groups based on UA (≥ 7 and < 7 mg/dL) and NT-proBNP (≥ 2279 and < 2279 ng/L) levels. All-cause mortality, HF hospitalization, and the composite endpoint of HF hospitalization or all-cause mortality rates were higher in the group with high UA and NT-proBNP levels (p < 0.001, p < 0.001, p < 0.001, respectively). Conclusion: Hyperuricemia alone is an independent predictor of all-cause mortality in chronic HF. However, the combination of UA and NT-proBNP appears to be a stronger predictor of poor outcomes.
