Background
The current outbreak of the coronavirus disease 2019 (COVID-19) has
caused many severe cases of pneumonia. A messenger RNA (mRNA) vaccine
against the COVID-19 virus has been in use since December 2020 [1].
However, this vaccine has been reported to cause adverse events,
including cardiovascular ones, and the underlying mechanisms of these
adverse events are unknown [2,3,4]. Herein, we report a rare case of
acute myocardial infarction shortly after COVID-19 vaccination and
partially clarify the pathogenesis of the acute myocardial infarction.
