红细胞分布宽度与射频消融术后房颤复发的关系

Relationship between red blood cell distribution width and recurrent atrial fibrillation after radiofrequency ablation

目的探讨阵发性房颤患者术前红细胞分布宽度(red blood cell distribution width,RDW)与射频消融术后房颤复发的关系。方法选取接受射频消融术的阵发性房颤患者150例,根据术前RDW水平分为RDW正常组(96例)和RDW升高组(54例)。随访观察并比较两组患者的房颤复发情况,采用回归分析探讨房颤消融术后复发的预测因素。结果RDW升高组患者超敏C反应蛋白(hs-CRP)水平高于RDW正常组患者(P<0.05),术后房颤复发率也高于RDW正常组(24.1%vs.11.5%,P<0.05);多元回归分析显示,RDW、房颤发作时间、左房内径、hs-CRP水平为射频消融术后房颤复发的独立预测因素。结论RDW升高的房颤患者在射频消融术后房颤复发率明显上升,对此类患者应加强干预。

Objective To investigate the relationship between red blood cell distribution width(RDW)and the recurrence of atrial fibrillation(AF)after radiofrequency ablation.Methods We selected 150 patients diagnosed with paroxysmal AF who had undergone radiofrequency ablation.They were divided into normal RDW group(96 cases)and elevated RDW group(54 cases)according to preoperative RDW level.The AF recurrence was followed up for observation and compared between the two groups;regression analysis was performed to explore the predictive factors of AF recurrence after ablation.Results In the elevated RDW group,the level of high sensitive C-reactive protein(hs-CRP)of patients is higher than that in the normal RDW group(P<0.05)while the recurrence rate of AF after ablation is also higher than that in the normal RDW group(24.1%vs.11.5%,P<0.05).Multivariate regression analysis shows that RDW,AF duration,left atrial diameter and hs-CRP level are independent predictors of AF recurrence after ablation.Conclusion Among the AF patients with increased RDW,the recurrence rate of AF after ablation significantly increases.Intervention measures should be strengthened for these patients.
