Heart:导管消融和抗心律失常药物治疗后房颤复发的性别差异

2022-03-26 MedSci原创 MedSci原创

虽然心房颤动导管消融后女性的心律结局比男性患者差,但老年女性的抗心律失常药物后反应优于男性。

性别差异正在成为各种心血管疾病的一个重要问题。心房颤动在韩国人群中的患病率已达到 1.6%,并且还在不断增加。心房颤动的发病率在男性中明显较高,但女性患心房颤动的比例随着年龄的增长而增加。此外,女性心房颤动导管消融后复发的风险高于男性。然而,目前尚不清楚复发患者的抗心律失常药物反应性是否存在性别差异。

近日,心脏病领域权威杂志Heart上发表了一篇研究文章,在2999例接受新生心房颤动导管消融的患者(26.5% 为女性,平均年龄为58.3±10.9岁,68.1%为阵发性心房颤动患者)中,研究人员比较和评估了1094例复发患者和788例随后接受抗心律失常药物进行节律控制患者节律结局的性别差异。

在48.2±34.9个月的随访中,1094例患者(36.5%)在接受心房颤动导管消融术后发生心房颤动复发,788例接受抗心律失常药物的患者中有508例(64.5%)发生心房颤动复发。

虽然心房颤动导管消融的节律结局在女性中更差(对数秩p=0.041,HR为1.28,95%CI为1.02至1.59,p=0.031),但女性术后复发后的抗心律失常药物反应优于男性(对数秩p=0.003,HR为0.75,95%CI为0.59至0.95,p=0.022),尤其是在60岁以上的女性中(对数秩p=0.003)。在使用抗心律失常药物后249名患者接受了重复手术,女性的肺静脉(PV)重新连接率(62.7% vs. 76.8%,p=0.048)低于男性,但不存在额外PV触发因素(37.8% vs. 25.4%,p=0.169)。

由此可见,虽然心房颤动导管消融后女性的心律结局比男性患者差,但老年女性的抗心律失常药物后反应优于男性。
