急性心肌梗死后二尖瓣返流与心房纤颤的关系

Relationship between atrial fibrillation and acute myocardial infarction with mitral regurgitation

目的:探讨急性心肌梗死(AMI)后缺血性二尖瓣返流与初发心房纤颤(atrial fibrillation,AF)的关系。方法:回顾性分析269例AMI患者的临床资料,排除既往有AF和原发瓣膜病的病例,根据二尖瓣返流程度分为2组:无返流组(n=165)和返流组(n=104)。AF通过住院期间心电图或心电监护诊断。结果:无返流组和返流组新发AF分别为15例(9.1%)和22例(21.2%)(P<0.01)。结论:AMI后二尖瓣返流与AF发生有密切的关系。

AIM： To explore the relationship between atrial fibrillation（AF） and acute myocardial infarction（AMI） with ischemic mitral regurgitation（MR）.METHODS： Clinical data of 269 consecutive patients with AMI were retrospectively analyzed.Patients with known AF and intrinsic valve disease were excluded.Study patients were divided into two groups based on the degree of MR diagnosed by echocardiography： no MR（Group A） and MR（Group B）.AF was diagnosed by electrocardiogram or monitoring at any time during the hospital stay.RESULTS： According to results of analysis,Group A included 165 patients and Group B included 104 patients.The number of newly developed cases of AF was 15（9.1%） patients and 22（21.2%） patients,respectively,in Group A and Group B（P0.01）.CONCLUSION： There is a close association between AF and AMI with MR.
