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 influential factors of acute myocardial infarction (AMI) complicated with atrial fibrillation (AF) and its effect on recent mortality. Methods: The clinical data of 476 AMI inpatients were analyzed. The patients were divided into AF group (46 cases) and non-AF group (430 cases) according to whether they were complicated with AF. The in-hospital mortality was compared between the two groups. Related risk factors. Results: The incidence of AMI complicated with AF was 9.7%. There was statistical difference between AF group and non-AF group in age, hypertension, admission rate, serum creatinine, hemoglobin, myocardial infarction range and left ventricular ejection fraction (P <0.05 or P <0.01). Mortality rate of AF group during hospitalization was 21.1% and that of non-AF group was 3.5% (P <0.01). Conclusion: AF is a common complication in patients with AMI and an independent risk factor for the recent death in patients with AMI.
