【摘要】 目的 观察心房颤动与冠状动脉硬化性心脏病(冠心病)的关系。方法 选择心房颤动并且临床初步诊断为冠心病的老年病例56例(心房颤动组)及经冠状动脉造影确诊为冠心病的老年病例50例(冠心病组)进行观察，分别检查血脂、心电图、活动平板运动试验、核素心肌灌注显像及冠状动脉造影检查。结果 冠心病组胆固醇(Ch)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)比心房颤动组高(Ch 6.50±1.95∶5.60±1.03，P<0.01；TG 2.03±0.63∶1.03±0.43，P<0.001；HDL-C 1.97±0.39∶1.03±0.34，P<0.01；单位：mmol/L)。冠心病组心电图、平板运动试验、核素心肌灌注扫描(SPECT)、冠状动脉造影等结果与心房颤动组比较也有显著不同(45∶11，P<0.001；47∶7，P<0.001；47∶5，P<0.001；50∶5，P<0.001)。结论 在老年心房颤动患者中冠心病发病率不高。

【Abstract】 Objective To investigate the relationship between atrial fibrillation and coronary heart disease. Method 56 elderly patients with atrial fibrillation (AF) suspicious of coronary heart disease (group AF)and 50 elderly patients without AF but with definite coronary heart disease (CHD,group CHD) were included in this study.Blood lipids,electrocardiography(ECG),treadmill exercise test(TET),single photon emission computed tomography(SPECT)and coronary arteriograhy were examined in all of them.The data from two groups were compared. Result Blood cholesterol,triglyceride,high density lipoprotein-cholesterol(HDL-C)levels in group CHD were significantly higher than those in group AF[(6.50±1.95)vs(5.60±1.03) ......
