许多急性心肌梗死(AMI)和心源性休克患者住院后得以幸存;但对他们随后的预后是鲜为人知的。

本研究旨在评估那些住院幸存者的心源性休克和出院后的死亡率以及全因住院之间的关联。

该研究的参与者包括ACTION Registry–GWTG试验的≥65岁的急性心肌梗死患者,这些患者为住院幸存下来的患者,并且研究人员链接到这些患者的医疗保险索赔数据。研究人员使用比例风险模型来检测心源性休克和结果之间的关联,调整了患者和医院的特点。风险比(HR)的报告分为早期(1至60天)和晚期(61〜365天)出院后的时间段。

在112668例AMI幸存者中,5%在住院期间曾患心源性休克。心源性休克患者死亡率在60天(9.6%对5.5%)和1年(22.4%对16.7%)时显著较高。调整了基线特征后,心源性休克患者死亡的风险在出院后头60天仍保持较高(调整后的HR:1.62; 95%可信区间(CI):1.46〜1.80),但此后类似于非休克患者(调整后的HR:1.08天61至365; 95%CI:1.00〜1.18)。休克患者的全因住院或死亡的发生率在60天(33.9%对24.9%)和1年(59.1%对52.3%)时明显较高。调整后,这一结果的风险也集中在前60天(调整后的HR:1.28; 95%CI:1.21至1.35),此后都是类似的(调整后的HR:61至365天为0.95; 95%CI:0.89至1.01)。

急性心肌梗死患者,心源性休克后幸存,在出院后一年有更高的死亡或再入院的风险。风险具有时间依赖性,主要发生在出院后早期,在此之后,有和无心源性休克患者的预后是相似的。
