NEJM:无ST段抬高的院外心脏骤停患者该何时血管造影?

2021-12-30 MedSci原创 MedSci原创

在没有ST段抬高的院外心脏骤停复苏的患者中,就30天全因死亡风险而言,即刻进行血管造影的策略与延迟或选择性策略相比并没有任何益处。

心肌梗塞是院外心脏骤停的常见原因。然而,在心电图上没有ST段抬高证据的复苏患者中,早期冠状动脉造影和血运重建的益处尚未明确。

近日,顶级医学期刊NEJM上发表了一篇研究文章,在这项多中心试验中,研究人员随机分配了554名可能是冠状动脉起源的院外心脏骤停成功复苏的患者,分别接受即刻冠状动脉造影(即刻血管造影组)或延迟或选择性血管造影。

所有患者在复苏后心电图上均未发现ST段抬高的证据。该研究的主要终点是30天时的任何原因死亡,该研究的次要终点包括30天时全因死亡或严重神经功能缺损的复合结局。

该研究主要分析纳入了554名患者中的530名(95.7%)受试者。在30天时,即刻血管造影组265名患者中的143名(54.0%)患者和延迟血管造影组265名患者中的122名(46.0%)患者死亡(风险比为1.28;95%置信区间[CI]为1.00到1.63;P=0.06)。与延迟血管造影组(248名患者中的138名[55.6%]患者)相比,即刻血管造影组(255名患者中的164名[64.3%]患者)更常发生死亡或严重神经功能缺损的复合事件。相对风险为1.16(95%CI为1.00到1.34)。两组的峰值肌钙蛋白释放值和中度或重度出血、卒中和肾脏替代治疗的发生率相似。

由此可见,在没有ST段抬高的院外心脏骤停复苏的患者中,就30天全因死亡风险而言,即刻进行血管造影的策略与延迟或选择性策略相比并没有任何益处。
