背景:高尿酸血症和痛风与心血管风险增加有关。别嘌呤醇是一种有效的降尿酸药物。是否降低尿酸的别嘌呤醇能改善高尿酸血症患者发生心血管风险尚不清楚。目标:在一项观察研究中,探讨别嘌呤醇对高尿酸血症患者心血管预后的影响。方法:研究者收集了丹麦菲英郡1992年到2010年间,高尿酸水平(≥6mg/dl)的患者。研究者联系了四个登记处;所有血液样本,医院住院和门诊患者,所有报销处方及死亡原因。研究者识别应用别

背景:高尿酸血症和痛风与心血管风险增加有关。别嘌呤醇是一种有效的降尿酸药物。降低尿酸的别嘌呤醇是否能改善高尿酸血症患者发生心血管风险尚不清楚。

目标:在一项观察研究中,探讨别嘌呤醇对高尿酸血症患者心血管预后的影响。

方法:研究者收集了丹麦菲英郡1992年到2010年间,高尿酸水平(≥6mg/dl)的患者。研究者联系了四个登记处;所有血液样本,医院住院和门诊患者,所有报销处方及死亡原因。研究者识别应用别嘌呤醇的患者,应用倾向性评分将其与相似尿酸水平但未进行降尿酸治疗的患者进行1:1配对。应用竞争风险回归模型计算HR值,相对于抗血小板试验协作的复合终点(心肌梗死、中风或心血管死亡)及各种原因死亡。

结果:65971名高尿酸血症患者, 7127例应用别嘌呤醇治疗。在倾向评分匹配队列研究中发现:与未应用别嘌呤醇治疗的患者,应用别嘌呤醇治疗的主要预后的HR值为0.89(95%CI  0.81 - 0.97)。各种原因死亡的相应HR值0.68(95%CI  0.62 - 0.74)。

结论:别嘌呤醇治疗可以降低高尿酸血症患者发生心血管疾病的风险。

Heart:别嘌呤醇或可降非致命性心梗风险

西班牙学者们在别嘌呤醇应用者中评估了其非致命性心肌梗死(AMI)风险,结果表明,别嘌呤醇与非致命性AMI风险减少有关,这种相关性似乎呈剂量依赖性和持续时间依赖性。论文1月5日在线发表于《心脏》(Heart)杂志。 该基于人群的病例对照研究纳入了年龄40至90岁的受试者。在主要分析中,研究者排除了既往用过别嘌呤醇或有AMI病史的患者。利用无条件逻辑回归模型校正混淆因素,通过OR值来评估
