Abstract

A 48-year-old man developed severe chest pain and became unconscious. Coronary cineangiography revealed single coronary artery of the type L2b by Sharbaugh and White. Ergonovine, 0.2 mg i.v., produced coronary arterial spasm in the right coronary artery. This case suggests that coronary arterial spasm might be a cause of sudden death in patients with single coronary artery. However, an association of single coronary artery and coronary arterial spasm might be coincidental.

摘要

一名48岁男性出现严重胸痛并失去意识。冠状动脉造影显示为Sharbaugh和White分类中的L2b型单冠状动脉。静脉注射0.2毫克麦角新碱后，右冠状动脉出现冠状动脉痉挛。该病例提示冠状动脉痉挛可能是单冠状动脉患者猝死的原因。然而，单冠状动脉与冠状动脉痉挛之间的关联可能是巧合。
