JACC:卒中后卵圆孔未闭封堵术,可减少卒中复发

2016-02-23 崔倩 译 MedSci原创

对于卵圆孔未闭(PFO)封堵加药物治疗 vs 单纯药物治疗隐源性脑卒中的效果是不确定的。研究人员进行了第一次汇总分析,该分析包括了已完成的随机试验中比较隐源性脑卒中患者进行PFO封堵 vs 药物治疗的个体参与者的数据。该分析包括对2个设备(STARFlex[伞式封堵器] [NMT Medical公司,马萨诸塞州波士顿市]和Amplatzer PFO封堵器[盘封堵器] [AGA医疗/圣犹达医疗用品,

关于卵圆孔未闭(PFO)封堵加药物治疗 vs 单纯药物治疗隐源性脑卒中的效果是不确定的。

研究人员进行了第一次汇总分析,该分析来自已完成的随机试验中的隐源性脑卒中患者的PFO封堵 vs 药物治疗的个体参与者的数据。

该分析包括对2个设备(STARFlex[伞式封堵器] [NMT Medical公司,马萨诸塞州波士顿市]和Amplatzer PFO封堵器[盘封堵器] [AGA医疗/圣犹达医疗用品,圣保罗,明尼苏达州])的数据在3项试验中进行评估。主要复合终点是卒中、短暂性脑缺血发作或死亡;次要结果为卒中。研究人员使用数秩检验和未调整的协变量调整Cox回归模型来比较封闭设备 vs 药物治疗。

2,303例患者中,封闭与主要复合终点不显著相关。这种差异在协变量调整后更加显著(危险比[HR]:0.68; P=0.049)。对于卒中的结果,所有的比较都有统计学显著性,未调整和调整的HRs分别为0.58(P=0.043)和0.58(P=0.044)。在限定于2个盘式封堵器试验分析中,封堵的效果对于主要复合结果不显著,但对于卒中结果较显著(未调整的HR:0.39; P=0.013)。亚组分析没有确定的治疗效果显著异质性。房颤在封堵的患者中更为常见。

在PFO和隐源性卒中患者中,封堵减少了卒中复发;调整的分析后,对于卒中、短暂性脑缺血发作和死亡的复合终点,封堵有显著统计学效果,但在未调整的分析中无显著统计学效果。
