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) in people with suspected heart failure?
Full literature searches, critical appraisals and evidence reviews were completed for all the specified review questions in order to identify the most accurate thresholds of pro-B-type natriuretic peptide (NT-proBNP) and B- type natriuretic peptide (BNP) to accurately identify heart failure as indicated by the reference standard for people with suspected heart failure.
