The authors found that female gender, in addition to diastolic function, is an independent predictor of brain natriuretic peptide levels in the elderly without systolic ventricular dysfunction.

clinical guidelines only recommend use of brain natriuretic peptide (BNP) levels for confirmation of diagnosis. After analyzing data from a large US registry, Fonarow and co-workers have found ...

Under normal conditions BNP is present in very low concentrations. In response to increases in ventricular volume or stress, levels increase significantly. In patients with heart failure ...

He had a proBNP natriuretic peptide level over 10,000 and an ejection fraction ... But it’s also great that his ejection fraction is now in the normal range and that his BNP is better.
