Criteria

Inclusion Criteria:

  • Ambulatory individuals 18 years and older who had been diagnosed with CHF (NYHA functional classes II-IV) for > 3 months
  • Left ventricular ejection fraction (LVEF) of ≤ 40 percent
  • Receiving indicated standard therapy (if not contraindicated or intolerant for > 3 months) defined as a diuretic, an ACE-inhibitor or an angiotensin receptor blocker (ARB) and a beta-blocke
  • Patients with NYHA class III or IV symptoms were also required to receive spironolactone. Doses of these drugs had to be stable for ≥ 3 months, except for diuretics, for which ≥ 1 month of stability was required.

Exclusion Criteria:

  • Hemodynamically severe uncorrected primary valvular disease
  • Active myocarditis
  • Hypertrophic cardiomyopathy
  • Restrictive cardiomyopathy
  • Myocardial infarction, stroke, unstable angina, coronary artery bypass graft surgery, valvular surgery, or angioplasty < 3 months before randomization
  • Symptomatic or sustained ventricular tachycardia not controlled by antiarrhythmic drugs or an implantable cardioverter-defibrillator
  • Any condition other than heart failure that would be expected to limit exercise (e.g., angina, peripheral vascular disease, pulmonary disease, arthritis, or an orthopedic problem severe enough to limit exercise)
  • Nursing mothers, pregnant women and those planning a pregnancy during the study period
