JAHA:肝硬化合并急性心肌梗死患者β受体阻滞剂的选择

2018-09-22 xing.T MedSci原创

由此可见,在肝硬化合并急性心肌梗死患者中,选择β受体阻滞剂是一个临床难题。该研究结果表明使用选择性β1受体阻断剂可降低主要心脏和脑血管事件的风险。

肝硬化合并急性心肌梗死患者是该服用选择性β1受体还是非选择性β-受体阻滞剂目前尚不清楚。近日,血管疾病领域权威杂志JAHA上针对这一问题发表了一篇研究文章。

在2001-2013年期间,研究人员从台湾NHIRD(国民健康保险研究数据库)检索了医疗记录。年龄<20岁、既往急性心肌梗死、β-受体阻滞剂禁忌症、慢性阻塞性肺病、哮喘或房室传导疾病的患者被排除在外。另外,在入院期间死亡、随访时间<6个月、选择性β1受体或非选择性β受体阻滞剂药物比率<80%或者在β-受体阻滞剂之间切换的患者也被排除在外。研究人员对选择性β1受体阻断剂和非选择性β受体阻滞剂的患者进行倾向评分匹配并比较结局。主要结局为1年和2年血管事件、肝脏不良结局和全因死亡率。

该研究共招募了203595名急性心肌梗死患者,其中6355例患有肝硬化。在筛选排除标准后,1769名患者(655名接受β受体阻滞剂治疗患者和1114名接受非β受体阻滞剂治疗患者)符合分析条件。在接受β受体阻滞剂治疗的患者中,研究人员进行了倾向评分匹配,分析了218名接受选择性β1受体阻滞剂治疗的患者和218名接受非选择性β受体阻滞剂治疗的患者。在2年的随访期间,接受选择性β1受体阻滞剂治疗的患者主要心脏和脑血管事件明显减少(风险比=0.62; 95%置信区间为0.42-0.91; P=0.014),全因死亡率降低(风险比=0.66; 95%置信区间为0.38-1.14; P=0.135)和肝脏结局不恶化(风险比=0.66; 95%置信区间为0.38-1.14; P=0.354)。

由此可见,在肝硬化合并急性心肌梗死患者中,选择β受体阻滞剂是一个临床难题。该研究结果表明使用选择性β1受体阻断剂可降低主要心脏和脑血管事件的风险。
