Five patients with typical myocardial stunning were presented. They had chest pain and had electrocardiographic abnormalities matching the symptoms of acute myocardial infarction (AMI) but had no coronary artery stenoses on angiogram (CAG). The prevalence of cases with these clinical manifestations was 1.2% among 415 consecutive AMI patients who were examined invasively. The electrocardiographic abnormalities varied; ST elevations were observed in 4 patients, R waves decreased transiently in one, and Q waves developed in one patient. Typical left ventriculogram (LVG) was akinesis in the apical, diaphragmatic and/or anterolateral segments, but hyperkinesis in the basal segments. This akinesis was transient and resolved in 7 days. CAG revealed diffuse multi-vessel spasms in 2 patients, which were also observed in additional 2 patients after ergonovine administration. The intracoronary administration of nitroglycerin disclosed no coronary artery stenoses in any of the patients.
本文报告了5例典型心肌顿抑患者。他们有胸痛症状，心电图异常与急性心肌梗死（AMI）相符，但冠状动脉造影（CAG）未发现冠状动脉狭窄。在415例接受有创检查的连续AMI患者中，具有这些临床表现的病例患病率为1.2%。心电图异常表现多样；4例患者出现ST段抬高，1例患者R波短暂降低，1例患者出现Q波。典型的左心室造影（LVG）显示心尖部、膈面和/或前外侧节段运动减弱，但基底节段运动增强。这种运动减弱是短暂的，7天内恢复。CAG显示2例患者有弥漫性多支血管痉挛，另外2例患者在给予麦角新碱后也观察到了这种情况。冠状动脉内注射硝酸甘油显示所有患者均无冠状动脉狭窄。
