Key result
COVID-19 mRNA vaccination linked to acute myocarditis with a favorable course in a 24-year-old male.
Why the study?
Increasing COVID-19 vaccination coverage will result in more vaccine-related side effects, including acute myocarditis.
Case Report (n=1)
No
Highlights the cardiac imaging findings, including CMR, of acute myocarditis as a potential side effect of COVID-19 mRNA vaccination.
May warrant myocarditis vigilance after BNT162b2 in young males; leaves open incidence and causality.
Increasing rates of coronavirus disease 2019 (COVID-19) vaccination coverage will result in more vaccine-related side effects, including acute myocarditis. In Korea, we present a 24-year-old male with acute myocarditis following COVID-19 vaccination (BNT162b2). His chest pain developed the day after vaccination and cardiac biomarkers were elevated. Echocardiography showed minimal pericardial effusion but normal myocardial contractility. Electrocardiography revealed diffuse ST elevation in lead II, and V2-5. Cardiac magnetic resonance images showed the high signal intensity of T2- short tau inversion recovery image, the high value of T2 mapping sequence, and late gadolinium enhancement in basal inferior and inferolateral wall. It was presumed that COVID-19 mRNA vaccination was probably responsible for acute myocarditis. Clinical course of the patient was favorable and he was discharged without any adverse event.

Kim et al. (2021) conducted a case report in Acute myocarditis (n=1). COVID-19 mRNA vaccination (BNT162b2) was evaluated. COVID-19 mRNA vaccination (BNT162b2) was associated with acute myocarditis in a 24-year-old male, who presented with chest pain and abnormal cardiac MRI but had a favorable clinical course.
