摘要 目的:观察血管紧张素转换酶抑制剂(ACEI)联合胺碘酮治疗能否改善心房颤动患者维持窦性心律的效果,并探讨其机制。方法:对83例持续性房颤患者予静脉注射胺碘酮复律成功后,在继续口服胺碘酮的基础上,依是否口服A-CEI类药物随机分为ACEI组(40例)和非ACEI组(43例),门诊随访1年,分别于3个月、6个月、9个月及12个月时检查窦性心律维持状况,并于复律后即刻、6个月、12个月查心电图计算P波离散度,于复律后即刻及12个月分别做超声心动图检查,测量左心房直径、左心室舒张末期直径、左心室射血分数等。结果:在随访9个月和12个月时,ACEI组维持窦性心律的效果明显优于非ACEI组(60.00%和30.23%,P<0.05;52.50%和23.25%,P<0.05)。在随访12个月时,ACEI组P波离散度较非ACEI组明显缩小[(37.50±7.54)ms和(48.57±3.78)ms,P=0.001],心脏彩超ACEI组缩小左心房直径明显优于非ACEI组[(3.23±0.15)cm和(3.50±0.28)cm,P=0.009]。结论:ACEI联合胺碘酮治疗能明显改善房颤患者窦性心律的维持,改善心房的电生理特性和左心房的重构。
