目的:探讨高敏C反应蛋白对持续性心房颤动患者射频消融术后复发的预测价值。

方法:筛选出我院以持续性心房颤动为第一诊断,并第一次进行射频消融手术的患者77例,根据随访时是否复发心房颤动分为复发组27例和未复发组50例。统计两组患者临床基线资料,进行Cox风险模型分析,筛选促使心房颤动复发的独立危险因素,并对高敏C反应蛋白水平进行受试者工作曲线(ROC曲线)绘制,评价其对心房颤动复发的预测价值。

结果:心房颤动复发与年龄(风险比=1.126,95%可信区间:1.044~1.215,P=0.002)、体重指数(风险比=1.297,95%可信区间:1.077~1.563,P=0.006)、高血压的分级(2级,风险比=4.142,95%可信区间:1.047~16.390,P=0.043;3级,风险比=8.595,95%可信区间:1.913~38.610,P=0.005)、左心房前后径(风险比=1.438,95%可信区间:1.212~1.707,P=0.000)以及高敏C反应蛋白水平(风险比=2.026,95%可信区间:1.010~4.061,P=0.047)相关。高敏C反应蛋白水平ROC曲线下面积为0.693(P=0.005),界值为0.355 mg/dl。

结论:持续性心房颤动消融术后复发与患者术前炎症活动状态相关,积极控制术前基础状态,可能会降低心房颤动复发,改善预后,减少不良心血管事件发生。

Abstract

Objective: To explore the predictive value of high-sensitivity C-reactive protein (hs-CRP) levels in patients with persistent atrial fibrillation (AF) recurrence after radiofrequency catheter ablation (RFCA).

Methods: A total of 77 patients of persistent AF as the first diagnosis with initial RFCA in our hospital were studied. The patients were divided into 2 groups: Recurrent group, n=27 and Non recurrent group, n=50. Basic clinical conditions were studied by Cox model analysis to screen the risk factors for AF recurrence, receiver operating characteristic (ROC) curve was conducted to assess the predictive value of hs-CRP level on AF recurrence.

Results: AF recurrence was related to the age (HR=1.126, 95% CI 1.044-1.215, P=0.002), body mass index (HR=1.297,95% CI 1.077-1.563, P=0.006), hypertension at stage II (HR=4.142, 95% CI 1.047-16.390, P=0.043), hypertension at stage III (HR=8.595, 95%CI 1.913-38.610, P=0.005), left atrial size (HR=1.438, 95% CI 1.212-1.707, P=0.000) and hs-CRP (HR=2.026,95% CI 1.010-4.061, P=0.047). The area under ROC curve of hs-CRP level was 0.693, P=0.005 with the cut-off point at 0.355 mg/dl.

Conclusion: Persistent AF recurrence after RFCA was related to pre-operative inflammatory status; actively control preoperative condition may reduce AF recurrence, improve prognosis and decrease adverse cardiovascular event in relevant patients.

心房颤动是成年人最常见的心律失常,危害性大,其不仅与我们熟知的卒中风险密切相关,而且与长期快速性心律失常所导致的心动过速性心肌病,以及心力衰竭的发生也有密切关系[1]。因此,近些年国内外学者均将注意力集中在心房颤动的预防和治疗上。……
