Coronary cine-angiograms of 1,042 patients were reviewed for the presence of ectasia of major coronary arteries. Ectasia or irregular dilatation of the coronary artery was defined as 1.5 times diffuse or segmental dilatation as compared to segment of normal caliber coronary artery. Forty-one (3.9%) patients were found to have diffuse or localised coronary artery dilatations with segments of normal caliber throughout the length of major vessels. Mean age of the patients was 52 years, and majority were males (39, 95%). Right coronary artery (RCA) and left circumflex (Cx) were involved in 23 (56%) each, left anterior descending (LAD) in 15 (37%), obtuse marginal in 4 (10%) and left main in 2 (5%). Multiple vessel involvement was present in 21 (51%). Evidence of myocardial infarction was present in 21 (51%). Major risk factors were not different from the patients with coronary artery disease without ectasia.
对1042例患者的冠状动脉造影影片进行回顾，以检查主要冠状动脉是否存在扩张。冠状动脉扩张或不规则扩张的定义为，与正常管径的冠状动脉节段相比，弥漫性或节段性扩张达1.5倍。发现41例（3.9%）患者的主要血管全程存在弥漫性或局限性冠状动脉扩张，且有正常管径的节段。患者的平均年龄为52岁，大多数为男性（39例，95%）。右冠状动脉（RCA）和左旋支（Cx）各有23例（56%）受累，左前降支（LAD）有15例（37%）受累，钝缘支有4例（10%）受累，左主干有2例（5%）受累。21例（51%）存在多支血管受累。21例（51%）有心肌梗死证据。主要危险因素与无扩张的冠心病患者无差异。
