NEJM:美托洛尔不能预防COPD患者加重恶化

在中度或重度慢性阻塞性肺病患者中,美托洛尔无法降低慢性阻塞性肺病患者的第一次加重恶化风险

观察研究表明,β-受体阻滞剂可能降低中重度慢性阻塞性肺疾病(COPD)患者的恶化和死亡风险,但这些发现尚未在随机试验中得到证实。

在这一前瞻性随机试验中,年龄在40至85岁之间的COPD患者分配给β受体阻滞剂(缓释美托洛尔)或安慰剂。患者均有慢性阻塞性肺病(COPD)的临床病史,同时有中度气流限制和加重的风险。研究的主要终点是治疗期间COPD第一次加重。

532例患者,平均年龄为65.0,1秒用力呼气量(FEV 1) 41.1%。研究发现,与安慰剂相比,美托洛尔组在第一次发作的中位时间无显著性差异,美托洛尔组为202天,安慰剂组为222天(HR 1.05),而且美托洛尔住院风险增加(危险比1.91)。治疗期间,美托洛尔组有11例死亡,安慰剂组有5例死亡。

在中度或重度慢性阻塞性肺病患者中,美托洛尔无法降低慢性阻塞性肺病患者的第一次加重恶化风险。
