title: Elevated B-type natriuretic peptide in asymptomatic men with chronic aortic regurgitation and preserved left ventricular systolic function.
abstract: Serum B-type natriuretic peptide (BNP) levels reflect myocardial strain and are known to be elevated in patients with heart failure. To determine if BNP levels are elevated in patients with aortic regurgitation, we measured BNP levels in patients with chronic asymptomatic aortic regurgitation and normal left ventricular systolic function.
