冠心病患者心房颤动与血清尿酸的相关性研究

目的 探讨冠心病患者心房颤动与血清尿酸水平的相关性.方法 选择住院治疗的冠心病患者247例,所有患者按有无心房颤动及心房颤动持续时间分为单纯冠心病组（90例）、冠心病合并阵发性心房颤动组（85例）和冠心病合并持续性/永久性心房颤动组（72例）.记录三组患者年龄、心血管相关病史、尿酸水平、心脏彩超情况及相关用药史,采用Logistic回归分析冠心病患者心房颤动发生的危险因素.结果 三组吸烟史、舒张压、体质量指数、总胆固醇、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇、肌酐、空腹血糖、餐后2h血糖、室间隔厚度、颈动脉内膜-中层厚度及用药史比较差异无统计学意义（P＞0.05）.冠心病合并阵发性心房颤动组和冠心病合并持续性/永久性心房颤动组年龄、收缩压、尿酸、左房内径（LAD）、左室舒张末期内径（LVEDD）明显高于单纯冠心病组,左室射血分数则明显低于单纯冠心病组,差异有统计学意义（P＜0.01或＜0.05）.Logistic回归分析显示：高尿酸、高龄、LAD和LVEDD增大是冠心病患者心房颤动的独立危险因素,其中尿酸水平与心房颤动相关性最显著（P=0.001,OR=1.061,95％ CI 1.026～1.096）.结论 高尿酸水平可能是冠心病患者发生心房颤动的危险因素.

The relationship between atrial fibrillation and serum uric acid level in patients with coronary heart disease

Objective To investigate the relationship between serum uric acid level and atrial fibrillation in patients with coronary heart disease.Methods Two hundred and forty-seven inpatients with coronary heart disease were selected.All the patients were divided into simple coronary heart disease group （90 cases）,coronary heart disease with paroxysmal atrial fibrillation group （85 cases） and coronary heart disease with continuous/permanent atrial fibrillation group （72 cases）.The age,history of cardiovascular events,uric acid,echocardiographic characteristics and drug-taking history were carefully recorded.The risk factors of atrial fibrillation in patients with coronary heart disease were analyzed by Logistic regression.Results The level of history of smoking,diastolic blood pressure,body mass index,total cholesterol,high density lipoprotein cholesterol,low density lipoprotein cholesterol,creatinine,fasting plasma glucose,postprandial 2 h plasma glucose,interventricular septal thickness,carotid intima-media thickness and drug-taking history among the 3 groups showed no statistical differences （P 〉 0.05）.The age,systolic blood pressure,uric acid,left atrial diameter （LAD）,left ventricular end diastolic diameter （LVEDD） in coronary heart disease with paroxysmal atrial fibrillation group and coronary heart disease with continuous/permanent atrial fibrillation group were significantly higher than those in simple coronary heart disease group,the left ventricular ejection fraction （LVEF） was significantly lower than that in simple coronary heart disease group,and there were statistical differences （P 〈 0.01 or 〈 0.05）.The result of Logistic regression analysis showed high uric acid,high age,expanded LAD and LVEDD were the independent risk factors of atrial fibrillation in patients with coronary heart disease,and uric acid showed the most significant correlation （P =0.001,OR =1.061,95% CI 1.026-1.096）.Conclusion High serum uric acid level maybe a risk factor of atrial fibrillation in p
