摘　　要：目的:探讨慢性心力衰竭(心衰)患者心房颤动(房颤)类型与红细胞压积(Hct)的关系。方法:对单中心射血分数≤50%的慢性心衰合并房颤患者进行回顾性分析。根据房颤类型分为阵发性房颤组和慢性房颤组,对两组包括Hct在内的各项临床指标进行统计学分析。结果:慢性房颤组Hct高于阵发性房颤组(P<0.01);多因素logistic回归分析显示Hct是房颤类型的独立危险因素(P<0.01);而射血分数(r=-0.436)、收缩压(r=-0.254)、舒张压(r=-0.217)与Hct呈负相关,左房内径(r=0.294)、左室内径(r=0.311)和体重指数(r=0.118)与Hct呈正相关(P<0.05,P<0.01)。结论:慢性房颤组Hct较阵发性房颤组高,慢性心衰患者Hct与房颤类型具相关性,Hct可作为监测慢性心衰合并房颤患者房颤病情进展的临床指标。Objective:To investigate the relationship between hematocrit and the pattern of atrial fibrillation in chronic heart failure patients.Method:A total of 231 adult patients diagnosed chronic heart failure with atrial fibrillation were identified over a 3-year.There were 91 patients with paroxysmal atrial fibrillation and 140 patients with chronic atrial fibrillation.The effect of each variable on atrial fibrillation and were hematocrit(Hct) assessed with statistic analysis.Results:Hct was higher in the chronic atrial fibrillation group than in the paroxysmal atrial fibrillation group(17.02±18.89vs 37.55±6.52,P<0.01).Hct(OR=1.265,95%Cl:1.098-1.458,P<0.01)was independently correlated with the pattern of atrial fibrillation in multivariate logistic regression analysis.Ejection fraction(r=-0.436,P<0.01),systolic blood pressure(r=-0.254,P<0.01)and diastolic blood pressure(r=-0.217,P<0.01)was negatively associated with Hct.Left atrial dimension(r=0.294,P<0.01),left ventricular dimension(r=0.311,P<0.01)and body mass index(r=0.118,P<0.05) was positively associated with Hct.Conclusion:Hct is independently correlated with the pattern of atrial fibrillation in chronic heart failure patients.
