JAMA:阿地溴铵长期心血管安全性研究

2019-05-09 MedSci MedSci原创

研究认为,对于高心血管疾病风险的慢性阻塞性肺病患者,阿地溴铵3年的长期心血管风险与安慰剂相当,且可以显著降低中度至重度慢性阻塞性肺病恶化风险

研究发现,长效M受体拮抗剂会增加慢性阻塞性肺疾病(COPD)患者的血管发病率或死亡率。近日研究人员考察了阿地溴铵对慢性阻塞性肺病患者血管疾病因素的影响。

3630名中重度COPD患者参与研究,存在心血管疾病史或2个以上动脉粥样硬化血栓的危险因素,随机通过干粉吸入器,每日两次分别服用阿地溴铵(n=1812)或安慰剂(n=1818) ,最长3年。研究的的安全终点是3年来首次主要心血管事件(MACE),疗效终点是治疗第一年COPD的年度恶化率。次要结果包括扩大MACE事件 (定义为第一次MACE或严重心血管事件的时间)和需要住院治疗的年恶化率。

在3589名患者中(平均年龄67.2岁,58.7%为男性),2537名患者(70.7%)完成了研究。其中,阿地溴铵组69例(3.9%)和安慰剂组76例(4.2%)患者出现MACE(HR=0.89),阿地溴铵组168例(9.4%)和安慰剂组160例(8.9%)患者(HR=1.03;单侧97.5%CI:0-1.28)出现扩大MACE事件。与安慰剂组相比,阿地溴铵组每年中重度恶化率(阿地溴铵组0.44,安慰剂组0.57,RR=0.78)和需要住院治疗的恶化率(阿地溴铵组 0.07,安慰剂组 0.10,RR=0.65)显著降低。最常见的不良事件为肺炎、尿路感染以及上呼吸道感染

研究认为,对于高心血管疾病风险的慢性阻塞性肺病患者,阿地溴铵3年的长期心血管风险与安慰剂相当,且可以显著降低中度至重度慢性阻塞性肺病恶化风险。
