摘要
目的 :探讨心肌梗死 (MI)急性期心房颤动 (房颤 )与冠状动脉病变的关系。方法 :在急性期 MI发病后连续 3～ 5 d心电监护中 ,38例有新出现的房颤 (房颤组 ) ,40例无房颤出现 (非房颤组 )。根据房颤发生的时间将房颤组又分为房颤早发亚组 (17例 ,房颤发生于 MI发病 2 4h内 )和房颤迟发亚组 (2 1例 ,房颤发生于 MI发病 2 4h后 ) ,比较两组间及两亚组间的冠状动脉造影结果。结果 :两组间比较 ,房颤组冠状动脉多支病变的发生率较高 (P <0 .0 5 )。两亚组间比较 ,房颤早发亚组梗死相关动脉以右冠状动脉近端阻塞为主 (P <0 .0 1) ,而房颤迟发亚组梗死相关动脉以左冠状动脉前降支阻塞为多 (P <0 .0 1)。结论 :MI急性期并发房颤的患者有较严重的冠状动脉病变 。
To study the correlation between atrial fibrillation(AF) in acute myocardial infarction (AMI) and coronary artery lesions.Method:38 patients who developed AF after the onset of AMI were classified into AF group.40 patients who did not develop AF after the onset of AMI were classified into non AF group.According to the onset time of AF,AF group was divided into two subgroups:subgroup 1 (n=17,AF developed within 24 hours after the onset of AMI)and subgroup 2(n=21,AF developed>24 hours after the onset of AMI).The angiographic outcomes were compared in two groups and in two subgroups.Result:The incidence of multivessel disease was significantly higher in AF group than in non AF group (P< 0.05 ).Occlusion of the right proximal coronary artery was responsible for AMI at a significantly higher in subgroup 1 than in subgroup 2(P< 0.01 ).Occlusion of the left anterior descending branch was responsible for AMI at a significantly higher in subgroup 2 than in subgroup 1(P< 0.01 ).Conclusion:The patients who developed AF in acute course of MI had more severe coronary artery lesion.The onset time of AF in AMI was related to the location of the infarct related coronary artery lesions.
