摘要
OBJECTIVE: This study sought to observe the effects of allopurinol on the cardiac function of non-hyperuricaemic patients with chronic heart failure and determine the safety of allopurinol for clinical applications. PATIENTS AND METHODS: A group of 125 consecutive cases of non-hyperuricaemic patients with chronic heart failure who were treated at Chongqing Emergency Medical Centre between July 2011 and June 2012 were enrolled and were randomly divided into allopurinol (300 mg/day) group (n= 62) and control group (n= 63). During the six months treatment period, levels of cardiac function, brachial artery endothelial function, inflammatory cytokines, and biochemical markers were routinely examined. RESULTS: After three months of allopurinol treatment, patients exhibited an increase in flow-mediated vasodilatation (FMD) of brachial artery, whereas, after six months of treatment, the cardiac function classification was improved; plasma levels of brain natriuretic peptide and tumour necrosis factor-alpha were decreased; left ventricular internal diameter was diminished; and the ejection fraction was increased (p<0.01 for all the parameters) in patients. Serum uric acid level was decreased during the treatment period for both groups, with no significant difference between the two groups. Liver and kidney dysfunction was not observed among the study participants, and no significant increase in creatine kinase level was detected for either treatment group. CONCLUSIONS: For non-hyperuricaemic patients with chronic heart failure, the addition of six months of allopurinol therapy was safe and effective. Moreover, in these patients, allopurinol treatment not only can significantly ameliorate the left ventricular function and reduce the level of inflammatory factors but could also improve endothelial function.
