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.	Baseline and Week 8
