NT-proBNP measurement is specifically used in patients undergoing which therapy?

Explanation:
NT-proBNP is measured because it reflects the patient’s own heart failure status without being affected by exogenous BNP therapy. Nesiritide is a recombinant BNP given to treat acute decompensated heart failure, and it can cause BNP immunoassays to be falsely elevated since they detect the administered peptide as well as endogenous BNP. NT-proBNP assays, by contrast, do not cross-react with nesiritide, so they provide a clearer picture of the patient’s cardiac status and prognosis when someone is receiving this therapy. This is why NT-proBNP measurement is specifically used in patients undergoing nesiritide therapy.
