B-type natriuretic peptide and ischemia in patients with stable coronary disease: data from the Heart and Soul study.

BACKGROUND In patients with symptoms of heart failure, elevations in B-type natriuretic peptide (BNP) accurately identify ventricular dysfunction. However, BNP levels are not specific for ventricular dysfunction in patients who do not have overt symptoms of heart failure, suggesting that other cardiac processes such as myocardial ischemia may also cause… CONTINUE READING
