Aims During the last decade, ablation has increasingly been used in rhythm control management of patients with atrial fibrillation (AF). Over time, experience and techniques have improved and indications for ablation have expanded. The purpose of this study was to investigate whether the recurrence rate of AF following ablation has improved during last decade. Methods and results Through Danish nationwide registers, all patients with first-time AF ablation, between 2005 and 2014 in Denmark were identified. Recurrent AF after ablation was identified with 1 year follow-up. A total of 5425 patients undergoing first-time ablation were included. While patient median age increased over time the median AF duration prior to ablation decreased. The rates of recurrent AF decreased from 45% in 2005-2006 to 31% 2013-2014 with the relative risk of recurrent AF almost halved with an odds ratio of 0.57 [95% confidence intervals (95% CI) 0.47-0.68] in 2013-2014 compared with patients undergoing ablation in 2005-2006. Female gender, hypertension, AF duration >2 years, and cardioversion within 1 year prior to ablation were all associated with an increased risk of recurrent AF. Conclusion One year risk of recurrent AF following first-time ablation has almost halved from 2006 to 2014. Hypertension, female sex, cardioversion 1 year prior to ablation, and AF duration for more than 2 years all increased the associated risk of recurrent AF.

2005 年至 2014 年消融后房颤复发率的时间趋势:丹麦全国队列研究

目的 在过去十年中,消融越来越多地用于心房颤动 (AF) 患者的节律控制管理。随着时间的推移,经验和技术得到了改进,消融的适应症也扩大了。本研究的目的是调查消融后房颤的复发率在过去十年中是否有所改善。方法和结果 通过丹麦全国登记,确定了 2005 年至 2014 年丹麦所有首次 AF 消融患者。1 年随访发现消融后复发性 AF。共纳入 5425 名接受首次消融的患者。虽然患者的中位年龄随时间增加,但消融前的中位 AF 持续时间减少。AF 复发率从 2005-2006 年的 45% 下降到 2013-2014 年的 31%,2013 年复发性 AF 的相对风险几乎减半,优势比为 0.57 [95% 置信区间 (95% CI) 0.47-0.68] -2014 年与 2005-2006 年接受消融的患者相比。女性、高血压、房颤持续时间 >2 年和消融前 1 年内复律都与房颤复发风险增加有关。结论 2006-2014年首次消融后一年房颤复发风险几乎减半。高血压、女性、消融前1年复律、房颤持续2年以上均增加房颤复发风险。女性、高血压、房颤持续时间 >2 年和消融前 1 年内复律都与房颤复发风险增加有关。结论 2006-2014年首次消融后一年房颤复发风险几乎减半。高血压、女性、消融前1年复律、房颤持续2年以上均增加房颤复发风险。女性、高血压、房颤持续时间 >2 年和消融前 1 年内复律都与房颤复发风险增加有关。结论 2006-2014年首次消融后一年房颤复发风险几乎减半。高血压、女性、消融前1年复律、房颤持续2年以上均增加房颤复发风险。
