摘要
目的:探讨非瓣膜性心房颤动(房颤)患者红细胞分布宽度(RDW)与评估房颤患者发生血栓栓塞风险的CHADS2和CHA2DS2-VASc评分的关系。方法:连续入选非瓣膜性房颤患者99例(其中阵发房颤68例,持续房颤31例),每例患者均进行CHADS2和CHA2DS2-VAsc评分,同时记录年龄、性别、伴发疾病、实验室指标及超声心动图结果。根据CHADS2及CHA2DS2-VASc评分将房颤患者发生血栓栓塞的风险分为低中危组和高危组,比较房颇患者发生血栓栓塞风险的低中危组与高危组各项指标的差异,同时探讨房颤患者RDW与CHADS2、CHA2DS2-VASc评分的关系。结果:无论何种分组方式,两组间年龄、高血压史、糖尿病史、冠心病史、脑卒中史有统计学差异(P〈0.05)。与低中危组相比,高危组患者年龄增加,RDW、血肌酐升高,左房直径增加,左室射血分数下降(P〈0.05)。多变量Logistic回归分析显示,RDW是房颤患者CHADS2、CHA2DS2-VASc评分的独立预测因素(OR值分别是2.184、3.815,均P〈0.05)。预测CHADS2高分的RDW的ROC曲线下面积为0.690(95%CI:0.583-0.797,P〈0.05),预测CHA2DS2-VASc高分的RDw的ROC曲线下面积为0.735(95%CI:0.634-0.836,P〈O.05)。结论:非瓣膜性房颇患者RDW与CHADS2和CHA2DS2-VASc评分呈正相关,而且是CHADS2、CHA2DS2-VASc评分的独立预测因素。
Objective: To investigate the relationship between red blood cell distribution width (RDW) and CHADS2, CHA2DS2-VASc score used for the evaluation of thromboembolism risk in patients with non-valvular atrial fibrillation (Af). Method: Our study included 99 patients with Af (68 with paroxysmal Af and 31 with persistent Af). We calculated CHADS2 and CHA2DS2-VASc risk score for each patient and recorded sex, age, comorbidities, laboratory parameters, and echocardiography. According to CHADS2 and CHA2DS2-VASc scores, we divided the Af patients into low-intermediate risk group and high risk group respectively, then compared the parameters between the two groups, and evaluated the relationship between RDW and CHADS2/CHA2DS2-VASc score in patients with Af. Result. The base characteristics between two groups had significant difference in sex, age, comorbidities, no matter using which kind of grouping method. High CHADS2, CHA2DS2-VASc score group had older age, higher RDW, creatinine, left atrial diameter and lower left ventricular ejection fraction, when compared to the low CHADS2, CHA2DS2-VASc score group. The multivariate logistic regression analysis was performed to predict high CHADS2, CHA2DS2-VASc scores. The results revealed that RDW was an independent predictor (OR: 2. 184, 3. 825, P〈0. 05). The area under the receiver-operating characteristic curve of RDW was 0. 690 (95%CI: 0. 583-0. 797, P〈0. 05) to predict high CHADS2 score and 0. 735 (95%CI: 0. 634-0. 836, P〈0.05) to predict high CHA2DS2-VASc score. Conclusion: RDW is significantly correlated with CHADS2 and CHA2DS2-VASc score in patients with Af, as well as an independent predictor of high CHADS2 and CHA2DS2- VASc score.
