术前干预对风湿性心脏病瓣膜置换术后心房颤动复律的影响

目的 探讨术前干预对风湿性心脏病瓣膜置换术后住院期间心房颤动发作的影响及其他影响因素.方法 将108例风湿性心脏病合并心房颤动行瓣膜置换术患者随机分为治疗组和对照组各54例.治疗组术前给予雷米普利、非洛地平、辛伐他汀三联治疗1个月及常规术前治疗;对照组只给予常规术前治疗.观察比较2组患者术后住院期间心房颤动发作情况.结果 治疗组与对照组复跳后即刻心房颤动的发生率差异无统计学意义(35.85%与41.51%,P=0.55),术后24 h心房颤动的发生率有统计学意义(39.62%与60.38%,χ2=4.57,P=0.03),住院期间心房颤动的发生率也有统计学意义(47.17%与69.81%,χ2=5.59,P=0.02).Logistic回归分析显示术前干预对术后住院期间心房颤动发作有影响(OR=0.39,95% CI0.17～0.86,P=0.018);影响心房颤动发作的主要因素还有左心房内径(OR=4.28,95% CI1.12～18.23,P=0.008)、心房颤动持续时间(OR=4.19,95%CI 1.15～14.22,P=0.011)、肺动脉压力(OR=3.28,95%CI 1.14～12.25,P=0.012)等.ROC曲线显示预测心房颤动时左心房内径最佳截点值为46.5 mm,预测房颤发作的敏感性为73%,特异度为85%;肺动脉压力最佳截点值为48.5 mm Hg,其敏感性为75.6%,特异度为80.3%;心房颤动持续时间最佳截点值为7.5个月,敏感性为76.1%,特异度为88.3%.结论 术前积极干预对心脏瓣膜置换术后住院期间可减少心房颤动的发生率,对术后窦性心律的维持也有有益的作用.

Abstract：

Objective To evaluate the influence of preoperation medical treatment on recurrence of atrial fibrillation(AF) in valve replacement postoperative patients of rheumatic heart disease during in-hospital and other risk factors. Methods One-hundred and eight patients with rheumatic heart disease and AF that underwent valve replacement postoperative patients were randomly divided into 2 groups: the treatment group (n =54)and the control group (n = 54 ). The treatment group were treated with ranipril, felodipine and simvastatin for 1 month and other conventional preoperational treatments before operation . The control group were only treated conventional preoperational therapy. Occurrence of AF postoperation were observed during inhospital. Results The occurrence of atrial fibrillation of the two group was no difference( 35.85% vs 41.51%,P = 0.55) immediately after rebeat. There was significant difference in the occurrence of atrial fibrillation of the 2 groups within 24 h post-operation ( 47.17% vs 69.81%, P = 0.02 ) . Logistic regression showed that intervention before operation had significant effect on the occurrence of AF( OR =0.39,95% CI: 0.17 -0.86,P =0.018) ,as well as the diameter of left atrium (LAD) ( OR= 4.28,95% CI:1.12 - 18.23, P = 0.018 ),pulmonary artery pressure(PAP) ( OR = 3.28,95% CI: 1.14 - 12.25, P = 0.01 ), duration of atrial fibrillation (AFD) (OR = 4.19,95% CI: 1.15 -14.22,P = 0.011). ROC curve showed that the best cut-off of LAD was 46.5 mm to predict AF,with sensitivity of 73% and specify of 85% ;the best cut-off of PAP was 48.5 mm Hg,with sensitivity of 75.6% and specify of 80.3% ;the best cut-off of AFD was 7. 5 months,with sensitivity of 76.1% and specify of 88.3%. Conclusion The recurrence of AF can be effectively reduced during hospitalization by the preoperational triple treatments for patients with rheumatic heart disease successfully underwent valve replacement operation , which is also beneficial for maintenance of sinus rhythm after operation.
