The purpose of this angiographic study was to make a review of patients with coronary artery ectasia (CAE) and to compare the average coronary artery diameters of proximal, middle and distal segments of the following three groups of coronary arteries: Group E (ectatic segments in patients with CAE and ischaemic heart disease), Group E-n (presumably normal segments in the same group of patients) and Group N (normal coronary arteries of control patients). It was found that distal segments of all three coronary arteries and the middle segment of the circumflex artery in Group E-n were significantly narrower than the corresponding segments in Group N (p = 0.001 or less than 0.05 respectively), which suggested the arteriosclerotic origin of both, CAE and distal coronary artery involvement.
这项血管造影研究的目的是回顾冠状动脉扩张（CAE）患者，并比较以下三组冠状动脉近端、中段和远端节段的平均冠状动脉直径：E组（CAE合并缺血性心脏病患者的扩张节段）、E-n组（同一组患者中推测为正常的节段）和N组（对照患者的正常冠状动脉）。研究发现，所有三支冠状动脉的远端节段以及E-n组中回旋支动脉的中段均明显窄于N组中的相应节段（分别为p = 0.001或小于0.05），这提示CAE和冠状动脉远端受累均起源于动脉粥样硬化。
