Özet

Several trials have been completed in patients with heart failure (HF) treated with uric acid (UA)-lowering agents with inconsistent results. We aimed to investigate whether lowering UA would have an effect on mortality and cardiovascular (CV) events in patients with HF in a systematic review and meta-analysis. The primary outcome measures were all-cause mortality, CV mortality, CV events, and CV hospitalization in patients with HF. We included 11 studies in our final analysis. Overall, allopurinol treatment was associated with a significant increase in the risk for all-cause mortality (hazard ratio [HR]: 1.24, 95% confidence interval [CI]: 1.04-1.49, P = .02). The trial heterogeneity is high (heterogeneity chi(2) = 37.3, I2 = 73%, P < .001). With regard to CV mortality, allopurinol treatment was associated with a 42% increased risk of CV mortality (HR: 1.42, 95% CI: 1.11-1.81, P = .005). There was a trend toward increased CV hospitalization in the same group (HR: 1.21, 95% CI: 0.95-1.53, P = .12). Uric acid-lowering treatments increase all-cause and CV mortality but did not increase CV hospitalization significantly in this study.
