Xanthine Oxidase Inhibition for Hyperuricemic Heart Failure Patients


Rochester, Minn.

Trial status:
Open for Enrollment
Why is this study being done?

The purpose of this study is to determine whether allopurinol is effective in relieving symptoms of patients with heart failure and high blood uric acid levels.

Who is eligible to participate?

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.
