摘要: Background: Worsening renal function (WRF) is frequently observed in patients with heart failure and associated worse outcome. The aim of this study was to examine the association cardiac serum marker N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) WRF. Methods: A total 125 consecutive a tertiary care outpatient clinic for prospectively underwent evaluation every 6 months. baseline NT-pro-BNP WRF analysed during follow up 18 months. Results: Twenty-eight (22.4%) developed (increase creatinine ≥0.3 mg/dL). Patients (2870 pg/mL, interquartile range (IQR) 1063–4765) had significantly higher values than without (547 pg/mL, IQR 173–1454). risk increased by 4.0 (95% CI 2.1–7.5) each standard deviation log NT-pro-BNP. In multivariable analysis including age, function, ejection fraction, New York Heart Association class diuretic dose, only diabetes were independent predictors WRF. At cut-off level 696 pg/mL, showed sensitivity 92.9% negative predictive value 96.4% WRF. Conclusion: strong predictor within 18 months systolic high value. Further studies are needed evaluate reno-protective strategies elevated
