Abstract

Background: B-type natriuretic peptide (BNP) is a neurohormone that can be measured in blood and is useful in patients with congestive heart failure (CHF). We compared whole blood BNP concentrations to distance walked during a 6-min walk test in patients with CHF. Methods: Forty-four patients with CHF underwent a 6-min walk test. The distance walked was compared to the BNP concentration on blood collected prior to the walk test. Patients were followed for 16±2.8 months after testing. Results: A significant correlation was observed between the BNP concentration and the distance walked (r=-0.47, p
