Circulation:ACUITY研究显示比伐卢定单药治疗安全降低ACS患者出血风险

 急性冠脉综合征患者基线心肌肌钙蛋白水平升高意味着预后较差。美国学者最新研究表明,合并慢性肾病的急性冠脉综合征患者,基线肌钙蛋白水平升高者往往长、短期预后较差。比伐卢定单药治疗能安全降低此类患者的出血风险和基线肌钙蛋白水平升高。该研究结果2012年2月21日在线发表于《循环》(Circulation)杂志。   在ACUITY(急性导管术和急诊介入治疗筛选策略)试验中,研究者收集13819例中危

 急性冠脉综合征患者基线心肌肌钙蛋白水平升高意味着预后较差。美国学者最新研究表明,合并慢性肾病的急性冠脉综合征患者,基线肌钙蛋白水平升高者往往长、短期预后较差。比伐卢定单药治疗能安全降低此类患者的出血风险和基线肌钙蛋白水平升高。该研究结果2012年2月21日在线发表于《循环》(Circulation)杂志。

  在ACUITY(急性导管术和急诊介入治疗筛选策略)试验中,研究者收集13819例中危和高危急性冠脉综合征患者随机接受肝素和一种血小板糖蛋白Ⅱb/Ⅲa抑制剂双药治疗、比伐卢定和一种血小板糖蛋白Ⅱb/Ⅲa抑制剂双药治疗、或比伐卢定单药治疗。在2179例慢性肾病[肌酐激酶(CK)<60 ml/min]合并急性冠脉综合征患者中,有1291例患者(59.2%)基线肌钙蛋白水平升高。

  研究发现,基线肌钙蛋白水平升高的慢性肾病患者较未升高者30天、1年的死亡率、心肌梗死和主要不良心血管事件(MACE)率更高。多变量分析发现,基线肌钙蛋白水平升高是慢性肾病患者30天[HR(95%CI)为2.05(1.48,2.83),P<0.0001]、1年 [1.72(1.36,2.17),P<0.0001]死亡或心梗的独立预测因素。
