Study objectives: In dyspneic patients without left ventricular enlargement, it may be difficult to differentiate between obstructive lung disease and diastolic heart failure. Determination of plasma brain natriuretic peptide (BNP) levels, known to increase with ventricular stretch, may be of clinical relevance in this situation. We compared the discriminant power of BNP blood levels and of echocardiography in patients with either chronic obstructive lung disease or diastolic heart failure.

Patients: Twenty-six New York Heart Association class III dyspneic patients with normal left ventricular systolic function were enrolled: 17 patients with chronic obstructive lung disease and 9 patients with unequivocal diastolic heart failure.

Results: Echocardiographic data were unable to accurately differentiate between the two groups, whereas BNP levels were significantly and markedly higher in patients with diastolic heart failure when compared to those with obstructive lung disease (224 ± 240 pg/mL vs 14 ± 12 pg/mL, p < 0.0001).

Conclusions: These preliminary results warrant a prospective, large-scale evaluation of the value of BNP assay for determining diastolic dysfunction, a common cause of dyspnea in elderly patients, and differentiating it from other diagnoses such as obstructive lung disease.
