目的探讨左房容积指数(LAVI,Left atrial volume index)与射频消融术后房颤远期复发的关系。方法选择接受环肺静脉电隔离射频消融术的房颤患者118例,并根据术后第12个月体表心电图和24h动态心电图监测及临床随访结果,分为房颤复发组和无复发组。分析房颤射频消融术后房颤复发的预测因素。结果复发与无复发组在年龄、性别、病程、左室射血分数等方面无统计学差异,复发组的左房容积指数大于无复发组,Logistic多元回归分析显示LAVI为房颤复发的独立危险因素(P<0.01)。结论 LAVI是房颤复发的独立预测因素。
Objective To investigate the relationship between left atrial volume index (LAVI) and long-term recurrence of atrial fibrillation after radio-frequency ablation. Methods One hundred and fourty-eight patients with atrial fibrillation who underwent radiofrequency catheter ablation of pulmonary vein were selected and divided into AF-recurrent group and non-recurrent AF group according to the body surface electrocardiogram and 24-hour ambulatory electrocardiogram monitoring and clinical follow-up results at the 12th month postoperatively. Predictors of recurrent atrial fibrillation after atrial fibrillation radiofrequency ablation. Results There was no significant difference in age, sex, course of disease, left ventricular ejection fraction between the recurrent and non-recurrent groups, and the left atrial volume index in the recurrent group was higher than that in the non-recurrent group. Logistic multiple regression analysis showed that LAVI was an independent risk of recurrence of atrial fibrillation Factor (P <0.01). Conclusion LAVI is an independent predictor of AF recurrence.
