冠状动脉痉挛在变异型心绞痛中的作用已经肯定,但其在运动诱发心绞痛和S-T段抬高中是否亦起有作用,则尚未明了。本文报道4例自发性及运动诱发的S-T段抬高,证实冠状动脉痉挛是运动诱发心绞痛及心电图改变的发病机理。
The role of coronary artery spasm in variant angina has been confirmed, but it remains unclear whether it plays a role in exercise-induced angina and elevation of the S-T segment. This article reports 4 cases of spontaneous and motor-induced S-T elevation, confirmed that coronary artery spasm is induced by exercise-induced angina and ECG changes in the pathogenesis.
