Abstract

B-type natriuretic peptide (BNP) is a cardiac neurohormone and is released as prepro BNP and then enzymatically cleaved to the N-terminal proBNP (NT-proBNP) and BNP upon ventricular myocyte stretch. Blood measurements of BNP and NT-proBNP have been used to identify patients with heart failure (HF). Clinical considerations for these tests include their half-lives in plasma, dependence on renal function for clearance, interpretation of their units of measure, and the rapid availability of the test results. The BNP assay is currently used as a diagnostic and prognostic aid in HF. In general, a BNP level below 100 pg/mL excludes acutely decompensated HF. Recombinant, human BNP (nesiritide) is an approved intravenous treatment for acute, decompensated HF. This paper reviews the literature concerning the use of this peptide as a diagnostic test and as an intravenous therapy.

In patients admitted to the emergency department with shortness of breath, BNP was more accurate than clinical history, physical examination, or laboratory values.

In patients with chronic kidney disease, BNP level remained an independent predictor of CHF. Renal function was found to influence the optimal cut point for BNP, particularly for those with eGFR less than 60 mL/min per 1.73 m2.

In this study, neurohormonal, clinical, and hemodynamic variables were analyzed in 452 patients with LVEF less than 35% over a 3-year period. Univariate predictors for sudden death included log BNP, log N-terminal ANP, big endothelin, and NYHA class. In the multivariate model, log BNP was the only independent predictor of sudden death, firmly establishing the role of BNP as a marker for sudden death in CHF.
