急性心肌梗死并心房纤颤的危险因子及预后

目的 :探讨急性心肌梗死 （AMI）并发心房纤颤 （房颤 ）的危险因子及房颤对 AMI预后的影响。方法 :比较 412例 AMI患者中并发房颤者与不并发房颤者的临床特征、住院其它并发症以及住院病死率。结果 :并发房颤组较不并发房颤组年龄大 ,肌酸磷酸激酶 （CPK）峰值高 ,左房内径大 ,入院时心功能差 ,但 L ogistic回归分析仅显示 CPK峰值、左房内径相差明显。并发房颤者病死率较无房颤者高 ,校正其它因素后仍明显。结论 :AMI并房颤者 CPK峰值高、左房内径大 ,住院病死率高 ,对该亚组应更积极的治疗。

Risk factors andprognostic significance of atrial fibrillation complicated by acute myocardial infarction

AIM:To investigate the risk factors and prognostic significance of atrial fibrillation following acute myocardial infarction (AMI). METHODS:Among 412 AMI patients,the clinical feature,other complications and in hospital mortality rate were compared between patients with and without atrial fibrillation. RESULTS:Compared with those without atrial fibrillation,the AMI patients with atrial fibrillation were older,had a higher peak of creatine kinase level,larger left atrial size,worse cardiac function. But logistic analysis indicated that differences existed only in peak creatine kinase level and left atrial size between the two groups. Patients with atrial fibrillation had a higher in hospital mortality rate than those without atrial fibrillation,and this rate remained significant after other risk factors were corrected. CONCLUSION:AMI patients with atrial fibrillation had a higher creatine kinase level,larger left atrial size and higher in hospital mortality rate,so these patients should receive more intensive care.
