糖皮质激素对阵发性心房颤动射频消融术后复发的影响

目的：探讨糖皮质激素的使用对阵发性心房颤动（AF）患者导管射频消融（RFCA）术后 AF 复发的影响。方法本研究连续入选2011年1月至2014年4月在该院心血管内科行环肺静脉 RFAC 术，并在术后使用糖皮质激素的阵发性 AF 患者50例（激素治疗组），并选取同期行 RFCA 术，术后未使用糖皮质激素的阵发性 AF 患者37例作对照组。术后1周、1个月、3个月、6个月、9个月、12个月，由固定医生进行电话或门诊随访，询问患者有无心悸症状或脉搏不齐，收集患者院外心电图报告，行十二导联心电图和24 h 动态心电图检查，分析、比较激素治疗组和对照组的 AF 复发情况。结果术后1周，激素治疗组和对照组窦性心律维持率分别为80．0％和54．1％，两组差异有统计学意义（P＜0．05），激素治疗组复发率显著降低；术后1个月，激素组和对照组窦性心律维持率分别为80．0％和67．6％，两组差异无统计学意义（P＝0．187）；激素组和对照组术后12个月的 AF 复发率差异无统计学意义（P＝0．711）。绘制 Kaplan-Meier 生存率曲线，行 Log-rank 检验，两组 AF 复发率差异无统计学意义（P ＝0．711）。结论术后早期小剂量糖皮质激素使用能够降低 RFCA 术后超早期（7 d 内）的房颤复发，但对术后极早期（术后1个月）和中期（术后12个月）房颤复发率无影响。

Effect of corticosteroids on paroxysmal atrial fibrillation recurrence after radio frequency catheter ablation

Objective To explore the effects of corticosteroids on the recurrence of atrial fibrillation (AF) after radio fre-quency catheter ablation (RFCA ) .Methods A total of 50 patients with paroxysmal AF who underwent RFCA and then treated with corticosteroids from January 2011 to April 2014 were enrolled in this study .At the same period ,37 patients with paroxysmal AF who also underwent RFAC but without corticosteroids treatment were selected as control group .The follow-up was carried out by the fixed physician at 1st week ,1st month ,3rd months ,6th months ,12th months after RFCA through a telephone visit or a hos-pital visit ,including the 12-lead electrocardiogram (ECG) and the HOLTER examination ,symptom of heart-throb inquiry and the interpretation of ECG ,AF recurrence were analyzed and compared between hormone treatment group and control group .Results After 1 week treatment ,the maintenance rates of sinus rhythm in treatment group and control group were 80 .0% and 54 .1% ,re-spectively ,there was statistic difference(P < 0 .05) ,the recurrence of AF in treatment group was significantly decreased ;after 1 month treatment ,the maintenance rates of sinus rhythm in treatment group and control group were 80 .0% and 67 .6% ,respective-ly ,there was no statistic difference(P = 0 .187) ;after 12 months treatment ,the recurrence of AF in treatment group and control group ,was not found statistic significance(P= 0 .711) .Kaplan-Meier survival rate was drew to conduct Log-rank test ,the difference of AF recurrence between the two groups was no statistic significance(P= 0 .711) .Conclusion Transient use of small amounts of corticosteroids after AF ablation may be effective for preventing AF recurrences within 1 week after ablation but it is not effective for preventing AF recurrences at 1st month and 12th months after ablation .
