目的:探讨红细胞分布宽度(RDW)和左心房容积(LAV)指数(LAVI)与心房颤动(AF)间的关系,筛选早期预测AF的指标。方法:108例非瓣膜性阵发性AF的患者为AF组和84例无AF患者为对照组,两组均进行体格检查和超声心动图影像学检查,全血细胞计数分析了RBC、RDW、中性粒细胞、中性粒细胞/淋巴细胞比值(NLR)及平均红细胞体积。比较两组人口学资料和超声心动图的资料。结果:AF组LAV、LAVI、RDW和hs-CRP均显著高于对照组(P<0.05)。两组NLR比较无明显差异(P>0.05)。多元Logistic回归分析显示:升高的LAVI、RDW和hs-CRP是非瓣膜性AF发生的独立预测因子。结论:升高的RDW水平和升高的LAVI可能是独立的非瓣膜性AF发生的预测危险因素。
Objective: To explore the relationship between RDW and LAVI and atrial fibrillation (AF), and to screen the indexes of early prediction of AF. Methods: One hundred and eighty nonvalvular paroxysmal AF patients were compared with AF group and 84 non AF patients as control group. Physical examination and echocardiography were performed in both groups. RBC, RDW, Neutrophil / lymphocyte ratio (NLR), and mean corpuscular volume. The demographic data and echocardiographic data were compared between the two groups. Results: LAV, LAVI, RDW and hs-CRP in AF group were significantly higher than those in control group (P <0.05). NLR no significant difference between the two groups (P> 0.05). Multivariate logistic regression analysis showed that elevated LAVI, RDW and hs-CRP were independent predictors of nonvalvular AF. Conclusions: Elevated RDW levels and elevated LAVI may be predictive risk factors for the development of independent nonvalvular AF.
