[Myocardial stunning due to simultaneous multivessel coronary spasms: a review of 5 cases]

J Cardiol. 1991;21(2):203-14.
[Article in Japanese]


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.
