Natriuretic peptides (BNP and NT-proBNP) are valuable biochemical markers for the diagnosis, risk stratification, and potentially guiding therapy in patients with heart failure.

Key Points

Review the physiological role, analytical measurement methods, and clinical utility of cardiac natriuretic peptides as diagnostic and prognostic biomarkers in heart failure.
Synthesized findings from over two decades of clinical and analytical research evaluating atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and their N-terminal prohormone fragments.
Evaluated assay methodologies, including competitive radioimmunoassays with trypsin digestion and automated noncompetitive immunometric assays.
Assessed diagnostic accuracy across clinical settings including emergency departments, primary care, and end-stage heart failure cohorts.
BNP and NT-proBNP demonstrate superior diagnostic and risk-stratification accuracy for left ventricular dysfunction and acute dyspnea compared to ANP and NT-proANP.
Natriuretic peptides show high negative predictive value for ruling out heart failure in primary care and emergency settings, though elevated levels also occur in renal failure and liver cirrhosis.
Processing-independent assays using trypsin pretreatment effectively quantify total proBNP fragments, while automated noncompetitive assays offer improved speed, analytical precision, and clinical practicality.
