What thresholds of pro-B-type natriuretic peptide (NT-proBNP) and B-type natriuretic peptide (BNP) are most accurate in identifying heart failure in people with suspected heart failure?
The optimal thresholds of pro-B-type natriuretic peptide (NT-proBNP) and B-type natriuretic peptide (BNP) for identifying heart failure in people with suspected heart failure have not been definitively established. However, in clinical practice, a NT-proBNP level of 500 ng/L or greater is often used as a diagnostic threshold for heart failure, while a BNP level of 200 ng/L or greater is typically used for the same purpose. Additional evidence is needed to validate the use of these thresholds and further refine the diagnostic process for heart failure.
