背景与目的: 高龄ACS患者接受侵入性治疗策略的频率较低,这可能对其生存率产生不利影响。本研究旨在探讨老年ACS患者的治疗策略,并比较侵入性治疗组与保守治疗组之间的预后差异。材料与方法:本项回顾性研究纳入了2018年11月至2023年10月期间在两家三级医疗机构就诊的连续年龄≥80岁的急性冠脉综合征(ACS)患者。侵入性治疗组包括接受经皮或外科血运重建的患者。保守治疗策略定义为仅接受指南指导的药物治疗。主要终点为随访六个月期间的全因死亡率。次要终点为复发性心肌梗死和心血管事件(CVI)。结果在670名急性冠脉综合征(ACS)患者中,中位年龄为83岁(81-86岁),女性占50.6%,其中429例(64%)接受侵入性治疗策略,241例(36%)接受保守治疗策略。在为期六个月的随访期间,共有176例(26%)患者死亡,保守治疗组的死亡率显著高于侵入性治疗组(ACS:37.8% vs. 19.3%)。p< 0.001;STEMI:49.4% 对比 26.8%,p< 0.001;NSTE-ACS:32.1% 对比 10.9%,p< 0.001)。复发性心肌梗死在2.5%的患者中被记录,而心血管事件(CVI)发生在1.2%的患者中,各治疗组之间无差异。多变量回归分析显示侵入性策略(HR = 0.48;95% CI:0.33–0.71;p< 0.001)作为 ACS 患者六个月生存期的阳性预测因子。结论侵入性治疗策略与老年ACS患者较低的死亡率相关,且与ACS类型无关。接受不同治疗方案的组别之间,复发性心肌梗死和心血管事件的发生率无显著差异。
