The number of participants with any change from Baseline in the NYHA Functional Class at Week 8 was calculated. Improved=class at the visit is decreased compared to baseline class, Unchanged=class at the visit is stable, Worsened=class at the visit is increased compared to baseline class.
Mean Plasma Brain Natriuretic Peptide Concentration at Baseline and Week 8	Baseline and Week 8	Brain natriuretic peptide is a surrogate marker of the severity of heart failure and was measured by a central laboratory.
