The clinical value of N-terminal pro-brain natriuretic peptide quantitative detection in diagnosis of heart failure / 国际检验医学杂志

ABSTRACT

Objective To evaluate the diagnostic value of N-terminal pro-brain natriuretic peptide (NT-proBNP) quantitative detection in patients with heart failure.Methods Quantitative enzyme-linked immunosorbent assay (ELISA) improvement method was applied to measuring serum level of NT-proBNP in patients with different degree of heart failure.Results The serum level of NT-proBNP was significantly elevated in patients with heart failure. With the increase of extent of heart failure, NT-proBNP increased in exponent. Receiver operator characteristic curve (ROC) showed that area under curve (AUC) was 0.898. The sensitivity and specificity were 91.9% and 92.3% respectively for diagnosis of heart failure.Conclusion Quantitative detection of NT-proBNP is at present the best laboratory test for evaluating heart function of patients with heart failure.
