目的评价阵发性心房颤动患者合并左心室舒张功能障碍的预测因素及心房颤动导管射频消融术对左心室舒张功能的影响。方法选取2011年11月至2012年6月北京安贞医院心内科阵发性心房颤动首次接受导管射频消融治疗患者158例,排除37例左心室射血分数〈50%者后,64例左心室舒张功能障碍者为观察组,57例左心室功能正常者为对照组。通过单因素及多因素分析评价阵发性心房颤动患者合并左心室舒张功能不全的危险因素,同时评价射频消融术对左心室舒张功能的影响。结果对照组年龄、伴随高血压者占比、左心房前后径、二尖瓣舒张晚期血流速度(A)峰值、二尖瓣舒张早期血流速度(E)峰值/舒张早期心肌运动速度(e’)均低于观察组,差异有统计学意义[年龄:(62±9)岁比(66±5)岁,伴随高血压:43.9%(25/57)比68.8%(44/64),左心房前后径:(39±4)mmIzL(41±4)mm,A峰:(59±20)em/s比(894-19)em/s,E/e’:(8.3±2.5)比(12.0±3.7),P〈0.05],对照组E/A高于观察组,组间差异有统计学意义『(1.47±0.42)比(0.85±0.26),P〈0.05]。左心室舒张功能不全相关因素多元回归分析显示,年龄、左心房前后径是左心室舒张功能不全的独立危险因素[年龄:比值比(DR)=1.098,95%置信区间(CI):1.034~1.165,P=0.002;左心房前后径:OR=1.128,95%CI:1.018—1.249,P=0.022]。术后6个月随访时,不服用抗心律失常药物情况下,观察组和对照组维持窦性心律的比例分别为79.7%(51/64)和82.5%(47/57),组间差异有统计学意义(P〈0.05);观察组左心室舒张功能至少提高1个级别者16例(25.0%)。观察组与对照组手术时间、射频时间、放射线时间和心包填塞发生率等差异无统计学意义(P〉0.05)。结论年龄和左心房前后径与阵发性心房颤动患者合并左心室舒张功能不全有关,应用心房颤动导管消融术治疗阵发性心房颤动患者合并左心室舒张功能不全安全有效。
Objective To find the predictors of left ventricular diastolic dysfunction (LVDD) in atrial fi- brillation(AF) patients and assess the effect of catheter ablation on LVDD. Methods A retrospective study of pa- tients (enrolled from November 2011 to June 2012) underwent ablation for paroxysmal AF. Two groups were com- pared: 64 patients with isolated LVDD; and 57 patients with normal left ventricular function. Results Age, hyper- tension, left atrial(LA) size, A peak, E/e' ratio were higher in LVDD group than in control group [age: (62 + 9 ) years vs (66 + 5 ) years, hypertension: 43.9% (25/57) vs 68.8% (44/64), LA size : ( 39 ~ 4) mm vs (41 ~ 4)mm, A: (59 +20)cm/s vs (89 + 19)cm/s, E/e': (8.3 ~2.5)vs ( 12.0 ~ 3.7), P 〈0.05]. E/A ratio was higher in control group [ ( 1.47 + 0.42) vs ( 0.85 + 0.26 ), P 〈 0.05 ]. In muhivariable regression analysis, age (0R=1.098, 95% CI: 1.034-1. 165, P=0.002) and LA size(OR=l.128, 95% CI: 1.018-1.249, P= 0.022 )were associated with LVDD. The primary end point was achieved in 79.7% (51/64)of patients with LVDD, and 82.5 % (47/57) in normal ones ( P 〈 0.05 ). In LVDD group, at least 1 grade improvement in diastolic dysfunc- tion demonstrated in 25% (16/64) of patients. The procedure time, ablation time, X-ray time and cardiac tampon- ade rate were of no statistics significant difference in the two groups (P 〉 0.05 ). Conclusion LVDD occurs frequently in paroxysmal AF; LVDD is associated with advancing age and LA size; catheter ablation of AF in LVDD patients is effective and safe.
