Coronary ectasia is an infrequent angiographic lesion commonly seen in stenotic coronary arteries. It may result in angina pectoris, even in myocardial infarction due to impaired coronary blood flow. A 70-year-old woman presented with chest pain that occurred after physical activity and lasted nearly 30 minutes. There were no pathologic findings except for a 2/6-degree systolic murmur on the left sternal border. Electrocardiography showed T-wave inversions in leads III, AVF, and V1-V3. Her chest pain did not recur following medical therapy in the coronary intensive care unit. Coronary angiography performed with the diagnosis of acute non-ST elevation myocardial infarction revealed segmental ectasia in both the left anterior descending and right coronary arteries without any obstructive lesion. The patient was discharged with medical therapy. She was followed-up for six months without chest pain.
