Abstract

Objectives: This study evaluated whether a xanthine oxidase (XO) inhibitor, oxypurinol, produces clinical benefits in patients with New York Heart Association functional class III to IV heart failure due to systolic dysfunction receiving optimal medical therapy. Background: Increased XO activity may contribute to heart failure pathophysiology. Methods: Patients (n = 405) were randomized to oxypurinol (600 mg/day) or placebo. Efficacy at 24 weeks was assessed using a composite end point comprising heart failure morbidity, mortality, and quality of life. Results: The percentage of patients characterized as improved, unchanged, or worsened did not differ between those receiving oxypurinol or placebo. Oxypurinol reduced serum uric acid (SUA) by ∼2 mg/dl (p <0.001). In a subgroup analysis, patients with elevated SUA (>9.5 mg/dl, n = 108) responded favorably to oxypurinol (p = 0.02 for interaction term), whereas oxypurinol patients with SUA
