摘要：目的：探讨急性心肌梗死（AMI）并发心房颤动（AF）的发生率、影响因素及对近期死亡率的影响。方法：分析476例AMI住院患者，将其分为房颤组46例，非房颤组430例，比较两组在院内死亡率，评估房颤对AMI患者近期死亡率的影响，并分析AMI患者发生房颤的相关危险因素。结果：476例患者有46例发生房颤，发生率为9.7%，单因素分析显示，房颤组与非房颤组在年龄、高血压、入院时心率、血肌酐水平、血红蛋白水平及心肌梗死范围、左心室射血分数等均有显著性差异（P<0.05或P<0.01）住院期间房颤组死亡率为21.1%，非房颤组为3.5%（P<0.01）。结论：房颤是AMI患者常见的并发症，是影响AMI患者近期死亡的独立危险因素，合并房颤的患者近期预后更差。

Abstract: Objective To evaluate the incidence,clinical features,influential factors and prognostic significance of atrial fibrillationr(Af) complicating acute myocardial infarction(AMI). Methods 476caese of AMI were hospitalized .Firstly,the patients were divided into Af group(46caese),Logistic regression analysis was used to identify the risk factor for Af. Then the patients were divided on the basis of in-hospital mortality into mortality group and non-mortality group. Regression analysis was used to assess the influence of Af on in-hospital mortality. Results New onset of Af was documented in 46 AMI patients(9.7%).There were significant differences between Af and non-Af patients in age,hypertension,MI extent,heart rate,LVEF,serum creatinine and hemoglobin level on admission . Af patients had higher in hospital mortality.Af was the independent risk factors for in-hospital mortality. Conclusion Af is a common complication of AMI and independently influences in-hospital mortality. Key words : acute myocardial infarction; atrial fibrillation; prognosis
