Primary Outcome Measures:
  • Change in Serum Potassium [ Time Frame: Baseline and 8 weeks ]
    Change in serum potassium from baseline to Week 8.

Secondary Outcome Measures:
  • Weight Loss at Week 1 [ Time Frame: Baseline and 1 week ]
  • Weight Loss at Week 2 [ Time Frame: Baseline and 2 weeks ]
  • Frequency of Marked or Disabling Exertional Dyspnea by Physician Assessment at Week 4 [ Time Frame: 4 weeks ]
    The frequency of marked or disabling exertional dyspnea was physician assessed based on physical exam at week 4.

  • Frequency of Marked or Disabling Exertional Dyspnea by Physician Assessment at Week 8 [ Time Frame: 8 weeks ]
    The frequency of marked or disabling exertional dyspnea was physician assessed based on physical exam at week 8.

  • Number of Patients Improving by at Least One NYHA Functional Class From Baseline to Week 8 [ Time Frame: Baseline and 8 weeks ]
  • 6MWT Distance at Week 8 [ Time Frame: Baseline and 8 weeks ]
    Increase in the 6 minute walk test (6MWT) distance from baseline to Week 8. The test was performed according to the American Thoracic Society (ATS)Guidelines 2002.
