目的观察厄贝沙坦联用胺碘酮在心房颤动(房颤)复律后维持窦性心律的作用及对左房大小的影响。方法选择住院的房颤复律的非瓣膜性持续性房颤患者83例,随机分为对照组(41例)和试验组(42例)。对照组给予胺碘酮,试验组用胺碘酮+厄贝沙坦。入选患者转复为窦性心律后即为试验起始时间,试验终点为转复后12个月。终点事件:症状或无症状房颤首次复发。结果试验组窦律维持率显著高于对照组(83.3%与61.0%,P<0.05),而左心房内径(LAD)显著小于对照组[(36.9±1.2)mm与(34.1±1.4)mm,P<0.05]。结论厄贝沙坦联用胺碘酮复律后维持窦性心律较单用胺碘酮更有效,并可逆转左房扩大。
Objective To observe the effect of irbesartan and amiodarone on the maintenance of sinus rhythm after cardioversion of atrial fibrillation (AF) and its effect on left atrial size. Methods Eighty-three patients with non-valvular persistent AF who were hospitalized with AF were randomly divided into control group (n = 41) and experimental group (n = 42). Amiodarone was given to the control group, and amiodarone plus irbesartan was used in the test group. The selected patients converted to sinus rhythm after the test start time, the end of the trial for 12 months after the transfer. End point: first recurrence of symptoms or asymptomatic atrial fibrillation. Results The maintenance rate of sinus rhythm in the experimental group was significantly higher than that in the control group (83.3% vs 61.0%, P <0.05), while the left atrium diameter (LAD) was significantly lower than that in the control group [(36.9 ± 1.2) mm vs (34.1 ± 1.4) P <0.05]. Conclusion Irbesartan with amiodarone cardioversion to maintain sinus rhythm than single with amiodarone more effective and can reverse the expansion of the left atrium.
