Brain natriuretic peptide and diastolic dysfunction in the elderly: influence of gender

Diastolic heart failure is common in the elderly, particularly women. Previous studies on the value of brain natriuretic peptide in diastolic dysfunction have been largely limited to male subjects. 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. The authors' data indicate that an optimal threshold of brain natriuretic peptide for detecting diastolic dysfunction should be gender-specific.
