Coronary Spasm and Optical Coherence Tomography Defined Plaque Erosion Causing ST-segment-elevation Acute Myocardial Infarction in a Patient with COVID-19 Pneumonia

J Cardiol Cases. 2020 Oct 8. doi: 10.1016/j.jccase.2020.09.012. Online ahead of print.


An 84-year-old man with coronavirus disease 2019 pneumonia developed ST-segment-elevation myocardial infarction and was brought to the catheterization laboratory. His angiogram showed a haziness in distal right coronary artery, and optical coherence tomography (OCT) exhibited vascular spasm and OCT-defined plaque erosion, which were thought to be the causes of non-obstructive myocardial infarction. <Learning objective: Severe acute respiratory syndrome coronavirus 2 infection provokes various complications, which include acute myocardial infarction (AMI). Nevertheless, the mechanisms and characteristics of AMI in patients with coronavirus disease 2019 have not been elucidated. In the present case, coronary spasm and optical coherence tomography (OCT)-defined plaque erosion were confirmed as the substrates of coronary thrombosis by the findings of intracoronary OCT.>.
