JAHA:对急性心肌梗死后β-阻滞剂治疗超过3年的疗效分析!

2018-03-03 xing.T MedSci原创

由此可见,AMI后β-受体阻滞剂治疗的有益作用可能局限在AMI后1年内。超过1年的长期β-受体阻滞剂治疗是否能够提供临床效益需要进一步的临床试验来证实。

急性心肌梗死(AMI)患者β-受体阻滞剂治疗的最佳持续时间仍是未知的。近日,心血管疾病领域权威杂志JAHA上发表了一篇研究文章,研究人员的目的是评估急性心肌梗死患者β-阻滞剂的长期效应。

研究人员招募了所有在2003年6月3日至2015年2月24日之间于国立首尔大学Bundang医院连续就诊的AMI患者。主要终点为5年全因死亡率,根据出院时、AMI一年后以及AMI三年后β-阻滞剂的使用情况。

在2592例患者中,接受β-阻滞剂治疗的患者在出院时、AMI后1年、AMI后3年以及AMI后5年的比例分别为72%、69%、63%和60%。接受β-受体阻滞剂治疗的患者有更好的临床特征,如年龄较小(62岁 vs. 65岁;P<0.001)。他们经常接受再灌注治疗(92% vs. 80%;P<0.001),相比于那些没有接受β-阻滞剂治疗的患者。在单变量分析中,接受β-阻滞剂治疗的患者在所有时间点的5年死亡率较低。在对显著协变量调整后的Cox模型中,出院时开出β-阻滞剂处方与死亡风险降低29%相关(风险比为0.71;95%可信区间为0.55-0.90;P =0.006);然而,AMI后1年和3年时开出β-阻滞剂处方与降低死亡无关。

由此可见,AMI后β-受体阻滞剂治疗的有益作用可能局限在AMI后1年内。超过1年的长期β-受体阻滞剂治疗是否能够提供临床效益需要进一步的临床试验来证实。
