brain type ( B type BNP ) natriuretic peptide in the detection of acute heart failure
Last reviewed 01/2018
- if suspected acute heart failure, use a single measurement of serum natriuretic peptides (B-type natriuretic peptide [BNP] or N-terminal pro-B-type natriuretic peptide [NT-proBNP]) and the following thresholds to rule out the diagnosis of heart failure:
- BNP less than 100 ng/litre
- NT-proBNP less than 300 ng/litre
- if presenting with new suspected acute heart failure with raised natriuretic
peptide levels, perform transthoracic Doppler 2D echocardiography to establish
the presence or absence of cardiac abnormalities
- consider performing transthoracic Doppler 2D echocardiography within 48 hours of admission to guide early specialist management
