Impact of Oxypurinol in Patients With Symptomatic Heart Failure
Open accessAbstract
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 approximately 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 <9.5 mg/dl exhibited a trend towards worsening. In addition, SUA reduction to oxypurinol correlated with favorable clinical response. Within the entire oxypurinol patient cohort, those characterized as either improved or unchanged had significantly greater reductions in SUA compared with patients who worsened (-2.3 +/- 2.1 mg/dl vs. -1.0 +/- 1.9 mg/dl, p = 0.0006). In placebo patients, lower baseline SUA, but not change in SUA, correlated with improved clinical outcome.Conclusions Oxypurinol did not produce clinical improvements in unselected patients with moderate-to-severe heart failure. However, post-hoc analysis suggests that benefits occur in patients with elevated SUA in a manner correlating with the degree of SUA reduction. Serum uric acid may serve as a valuable biomarker to target XO inhibition in heart failure. (Oxypurinol Compared With Placebo for Class III-IV NYHA Congestive Heart Failure; NCT00063687).

“Despite these initial results, subsequent trials with larger number of patients have failed to report substantial positive effects as compared with the placebo groups (361, 405), although the meta-analysis of available studies indicates some improvement of cardiovascular function (430).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
