摘　　要：目的 :本研究旨在探讨心房纤颤对风湿性心脏病患者胸主动脉重构的影响。方法 :研究对象包括 71例风湿性心脏病患者 ,其中房颤组 37例 ,非房颤组 34例。对所有患者均进行胸主动脉经食管超声扫描。分别测量舒张期和收缩期内径 (Dd,Ds) ,以及内膜 -中层厚度 (IMT) ;计算 Peterson s弹性指数 (Ep) ,Young s弹性指数(Es)和僵硬度指数 (β)。结果 :房颤组主动脉收缩期内径和舒张期内径增加 ,扩张性减低 ,内膜 -中层厚度和僵硬度增加 ,弹性指数无明显改变。结论 :心房纤颤是主动脉重构的促进因素 ,可使主动脉内径增加 ,还可导致内膜Objective:To evaluate the affection of atrial fibrillation(AF)on aortic remodelling.Methods:This study consisted of 71 patients with rheumatic heart disease(RHD).There were 37 patients with AF(AF Group),and 34 patients wihout(non AF Group).Transesophageal echocardiography was performed in all patients according to conventional method,and aorta was thoroughly examined,Diastolic and systolic diameter(Dd,Ds)and intimal medial thickness(IMT)was measured,Petersons elastic modulus(Ep),Youngs circumferential static modulus(Es)and stiffness index(β)was calculated.Results:In AF Group,the IMT,Dd,Ds and stiffness index(β)of aorta was signficantly higher( P <0 001～0 05)than that in non AF Group.Conclusions:Atrial fibrillation is risk factor of aortic remodelling.
