急性心肌梗死并发心房颤动的相关因素及近期预后分析

Influential factors and prognostic analysis of acute myocardial infarction complicating atrial fibrillation

目的:探讨急性心肌梗死(AMI)并发心房颤动(AF)的影响因素及其对近期死亡率的影响。方法:分析476例AMI住院患者的临床资料,根据是否并发AF将其分为AF组(46例)和非AF组(430例),比较两组的院内死亡率,并分析AMI患者发生AF的相关危险因素。结果:AMI并发AF的发生率为9.7%,AF组与非AF组的年龄、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、左心室射血分数等差异均有统计学意义(P<0.05或P<0.01),住院期间AF组死亡率为21.1%,非AF组为3.5%(P<0.01)。结论:AF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。

Objective： To investigate the influencing factors of acute myocardial infarction（ AMI） complicated with atrial fibrillation（ AF） and its effect on the recent mortality. Methods： The data of 476 hospitalized patients with AMI were analyzed. According to AMI with or without AF the patients were divided into AF group（ 46 cases） and non AF group（ 430 cases）. The hospital mortality was compared between the two groups and it＇s related risk factors were analyzed. Results： The incidence of AMI complicated with AF was 9. 7%. Age,hypertension,heart rate,serum creatinine,hemoglobin and myocardial infarction size and left ventricular ejection fraction were statistically significant between the AF group and non AF group（ P〈0. 05 or P〈0. 01）. During hospitalization,the mortality rate of AF group was 21. 1%,and non AF group was 3. 5%（ P〈0. 01）. Conclusion： AF is a common complication of AMI and an independently risk factor for the recent death of AMI patients.
