抗血栓治疗联合经皮冠状动脉介入治疗(PCI)治疗风险较高的心房颤动(AF)老年患者的急性心肌梗死(MI)的效果仍不清楚。

这项研究旨在确定适当的抗血栓治疗方法治疗通过PCI治疗房颤的急性MI患者。

研究人员对4,959例≥65岁的急性MI和AF并接受冠状动脉支架置入术(急性冠脉综合治疗及干预结果网络登记处)患者进行了研究。主要的有效性终点为2年的主要不良心脏事件(MACE),包括死亡,因MI再住院或卒中;主要安全性结果在因出血而入院情况。双重抗血小板治疗(DAPT)或三联治疗(DAPT加华法林)的结果采用经过逆概率加权倾向调整的Cox比例风险模型进行了比较。

在4,959例患者中,27.6%(n=1,370)进行三联疗法治疗。相对于DAPT,经过三联疗法的患者有着类似的MACE风险(调整后的危险比[HR]:0.99[95%置信区间(Cl):0.86〜1.16]),但出血需要住院风险显著增加(调整后的HR:1.61 [95%Cl:1.31〜1.97]),以及颅内出血风险增加(调整后的HR:2.04[95%Cl:1.25〜3.34])。在医疗保险部分的1591例患者中,服用华法林90天后的患者坚持使用华法林的患者为93.2%(n=412)。90天的具有里程碑意义的结果分析比较了持续服用华法林和不服用华法林患者进行三联疗法和DAPT治疗结果。

大约有1/4的接受PCI治疗MI的老年AF患者采用三联疗法。那些接受三联疗法与DAPT的患者大出血概率较高,但在MI,死亡,或中风复合事件中无可测量的差异。
