摘要
目的 探讨二尖瓣狭窄并发心房颤动 (房颤 )的危险因素。方法 采用非条件Logistic回归模型对连续行二尖瓣球囊扩张术 (PBMV)的 2 6 0例二尖瓣狭窄患者进行并发房颤的危险因素分析。PBMV后对房颤患者进行复律治疗并随访。结果 二尖瓣狭窄并发房颤的预测因子是左心房内径 (P <0 0 0 0 1)、年龄 (P <0 0 0 0 1)及病程 (P =0 0 0 0 7)。PBMV后左心房内径缩小 ,113例患者经药物或直流电转复窦性心律 ;随访 (12± 6 8)个月 ,31例 (2 8 2 % )患者房颤复发 ,左心房内径 (P <0 0 0 01)是转复窦性心律患者房颤复发的独立预测因子。结论 左心房内径、年龄和病程是决定二尖瓣狭窄患者发生房颤的最重要的因素。左心房内径也是决定PBMV后转复窦性心律患者能否维持窦性心律的主要因素。
Objective To investigate the factors that determine the occurrence of atrial fibrillation in patients with mitral stenosis Method 260 patients with rheumatic mitral stenosis underwent percutaneous balloon valvuloplasty (PBMV) Multiple logistic regression analysis was used to determine independent predictors of atrial fibrillation The 116 patients with mitral stenosis with atrial fibrillation received cardioversion after PBMV Results Multiple logistic regression analysis showed that left atrial diameter ( P <0 000?1), age ( P <0 000?1) and course of disease ( P =0 000?7) were predictors of the atrial fibrillation in patients with mitral stenosis After PBMV, the left atrial diameter of them was reduced and 113 patients with atrial fibrillation were converted to sinus rhythm with oral quinidine or current electrical defibrillation During the follow up period (12±6 8 months), 31 patients had recurrence of atrial fibrillation The left atrial diameter ( P <0 000?1) was independent predictor of recurrence of the atrial fibrillation Conclusion The study indicated left atrial enlargement, age and course of disease were the dangerous factors that determine the occurence of atrial fibrillation in patients with mitral stenosis and left atrial diameter also was chief factor that determine the recurrence of atrial fibrillation in patients who were converted to sinus rhythm after PBMV
