老年心房纤颤与冠心病

Atrial fibrillation and coronary artery disease in elderly persons

对 2 6例经过冠状动脉造影的老年心房纤颤患者做回顾性分析。将患者分为 2组 ,第 1组 17例 ,无心电图心肌缺血证据 ;第 2组 9例 ,有心电图心肌缺血证据。结果显示 ,第 1,2组分别有 2 (11.8% )和 8(88.9% )例患者存在 1支以上冠状动脉大于管腔直径 5 0 %的狭窄 ,被诊断为冠心病。2组之间差异显著 (P<0 .0 1)。结果提示 ,当无心电图心肌缺血依据时 。

The data of 26 aged patients with atrial fibrillation, who had undergone selective coronary angiography, was retrospectively studied. The patients were divided into two groups. Group1:17 patients without electrocardiographic evidence of cardiac ischemia, and group2:9 patients with electrocardiographic evidence of cardiac ischemia . The results showed that group 1 and 2 had, respectively, 2(11.8%) and 8(88.9%)patients who had more than 50% narrowing in transverse diameter in at least one branch of coronary artery and was diagnosed as coronary artery disease(CAD). The incidences of CAD between the two groups were significantly different ( P <0.01). The results suggested that atrial fibrillation in elderly persons might not be attributed to CAD when without electrocardiographic evidence of cardiac ischemia.
