ABSTRACT
Background: : : :Coronary artery ectasia is an abnormal enlargement of coronary artery and infrequently associated with acute coronary syndrome. The prognosis, treatment, and etiology of this disease remain unclear. Method:
Sixtyone patients (35 male and 26 female, 53±11.0 years) out of 4,694 patients who underwent diagnostic coronary angiography at Chonnam National University Hospital between January 1996 and March 1999, and diagnosed as isolated coronary artery dilatatation without significant stenosis, were analyzed retrospectively. Results: : :The : incidence of coronary artery ectasia on the coronary angiography was 1.29%. Smoking was the most frequently associated risk factor. Clinical diagnosis was 16 (26.2%) cases of stable angina, 29 (47.5%) unstable angina, 9 (14.7%) acute myocardial infarction, 5 (8.1%) old myocardial infarction, and 2 (3.3%) variant angina. Right coronary artery was the most frequent involved artery (42.5%). Type Ⅰ according to Markins’ classification was 63.9%. Proximal part of coronary artery was the most common involved arterial segment. Aspirin (78.7%), calcium antagonist (73.8%), nitrate (29.5%) and β-blocker (12%) were used. During clinical follow-up of 12±
10.5 months, there were no major cardiac event in all patients. Conclusion: : : :The incidence of the coronary artery ectasia in Korean patients was relatively rare, and long-term prognosis was good. ((((Korean Circulation J 2000;

서 론
관상동맥 확장증(coronary artery ectasia:CAE)은
관상동맥의 비정상적인 확장, 확대를 지칭하는데 일반적 으로 인접한 정상적인 관상동맥 분절보다 1.5배 이상 늘어난 경우를 말한다.
1)이러한 관상동맥의 확장은 보 통 전반적인 관상동맥의 확장성 변화의 형태를 취하지 만, 국소적인 형태나 이의 혼합된 형태의 확장성 변화 를 보이기도 한다.
2)3)관상동맥의 확장은 관상동맥경화 증과 관련된다고 알려져 있으며, 확장 부위에서 느린 관상동맥 혈류를 동반하기도 하고 심근허혈로 인한 협
