In people with suspected heart failure, what thresholds of pro-B-type natriuretic peptide (NT-proBNP) and B-type natriuretic peptide (BNP) are most accurate in identifying heart failure (as indicated by the reference standard)?
The most accurate thresholds for pro-B-type natriuretic peptide (NT-proBNP) and B-type natriuretic peptide (BNP) in identifying heart failure (as indicated by the reference standard) in people with suspected heart failure are based on studies which indicate that NT-proBNP levels of greater than 125pg/mL and BNP levels of greater than 90pg/mL are associated with a high probability of heart failure in this population.
