Conclusion: Anaemia and renal dysfunction are related to increased BNP and NT-proBNP levels, independent of the severity of HF. These optimal cut-off values determined by receiver operating characteristic curves, approximately 10 % of the patients proBNP levels are influenced by several other factors such as age, sex, obesity and renal function [4–10]. Another factor that might influence BNP and NT-proBNP levels in patients with HF is anaemia, which is relativel
