NEJM:非心脏手术患者围术期用阿司匹林或可乐定不改善预后(POISE-2研究)

2014-04-02 小田 译 医学论坛网

2014年美国心脏病学会年会(ACC 2014)公布的POISE-2研究表明,在接受非心脏手术的患者中,围术期应用阿司匹林或可乐定(clonidine)均不能减少患者死亡或心肌梗死发生率,应用阿司匹林还与额外严重出血显著相关,可乐定则与额外临床低血压、心动过缓和非致命性心搏骤停显著相关。大出血和低血压是术后心肌梗死的预测因子。研究3月31日在线发表于《新英格兰医学杂志。 研究纳入接受非心脏手

2014年美国心脏病学会年会(ACC 2014)公布的POISE-2研究表明,在接受非心脏手术的患者中,围术期应用阿司匹林或可乐定(clonidine)均不能减少患者死亡或心肌梗死发生率,应用阿司匹林还与额外严重出血显著相关,可乐定则与额外临床低血压、心动过缓和非致命性心搏骤停显著相关。大出血和低血压是术后心肌梗死的预测因子。研究3月31日在线发表于《新英格兰医学杂志。

研究纳入接受非心脏手术患者并将其随机分为围术期阿司匹林组(n = 4998) 和安慰剂组 (n = 5012)。术前给予相应患者阿司匹林200 mg。在那些既往未应用阿司匹林的患者,则继续给予该药至术后30天;既往应用了阿司匹林的患者,在术前1周停药,术后继续给药7天,然后继续恢复常规阿司匹林治疗。

共10010例患者纳入随机化研究,平均年龄为69岁,女性47%,糖尿病38%,冠状动脉疾病23%(其中既往支架置入和冠脉旁路移植术百分比分别为4.7%和4.8%),外周动脉疾病8.8%,卒中病史5.0%。大血管外科手术率为4.9%,术前他汀类药物和β受体阻滞剂应用率分别为37%和23%。

阿司匹林和安慰剂的结果比较


阿司匹林组和安慰剂组死亡和心肌梗死的主要转归分别为7.0%和7.1%(P= 0.92)。可乐定对阿司匹林无影响。在那些术前未给予阿司匹林的患者中,围术期给予阿司匹林与卒中风险减少相关,但只是很少的事件减少。

阿司匹林和可乐定的结果比较

阿司匹林组和组死亡和心肌梗死的主要转归分别为7.3%和6.8%(P = 0.29)。阿司匹林对可乐定无影响。在那些术前未给予阿司匹林的患者中,围术期给予阿司匹林与卒中风险减少相关,但只是很少的事件减少。那些未接受神经阻滞麻醉的患者自从应用了可乐定后情况似乎有恶化趋势(相互作用的P值为0.01)。
