Primary Outcome Measures:
  • A Composite Clinical Endpoint (CCE) That Classifies Subject's Clinical Status as Improved, Worsened, or Unchanged. [ Time Frame: 24 Weeks ]
    CCE composed of 3-level categorical variable with options that include worsened, unchanged or improved


Secondary Outcome Measures:
  • Change in Quality of Life (KCCQ). [ Time Frame: Baseline to 12 weeks ]
    Kansas City Cardiomyopathy (KCCQ) overall summary score - The Kansas City Cardiomyopathy Questionnaire is a 23-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. In the KCCQ, an overall summary score can be derived from the physical function, symptom (frequency and severity), social function and quality of life domains. Scores are transformed to a range of 0-100, in which higher scores reflect better health status.

  • Change in Submaximal Exercise Capacity (6-MWT) [ Time Frame: Baseline to 12 weeks ]
    6-Minute Walk Test

  • Change in Quality of Life (KCCQ) [ Time Frame: Baseline to 24 weeks ]

Criteria

Inclusion Criteria:

  • NYHA class II-IV heart failure due to ischemic or non-ischemic cardiomyopathy.
  • Left ventricular ejection fraction ≤ 40% by echocardiography- Heart failure symptoms for 3 months despite standard treatment.
  • Serum uric acid level ≥ 9.5 mg/dl.
  • At least one of the following additional markers of increased risk: Hospitalization, ER visit or urgent clinic visit for heart failure requiring IV diuretics within the previous 12 months; Left ventricular ejection fraction ≤ 25; B-type natriuretic peptide level > 250 pg/ml

Exclusion Criteria:

  • Hypertrophic or restrictive cardiomyopathy, constrictive pericarditis, biopsy-proven myocarditis, severe stenotic valvular disease, or complex congenital heart disease.
  • Acute coronary syndrome, PCI or CABG within 3 months.
  • Current ventricular assist device or ventricular assist device or heart transplant likely within the next 6 months.
  • Uncontrolled hypertension (i.e., SBP > 170 mm Hg or DBP > 110 mm Hg)
  • Serum creatinine > 3 mg/dL or estimated GFR < 20 ml/min.
  • Evidence of active hepatitis with ALT and AST greater than 3x normal.
  • Any condition other than HF which could limit the ability to perform a 6-minute walk test
  • Any diseases other than HF which are likely to alter the patient's global perception of status or quality of life over a period of 6 months.
  • Receiving treatment with allopurinol currently or within 30 days, or having symptomatic hyperuricemia which requires treatment with allopurinol.
