Does the Moderna COVID-19 vaccine cause myocarditis in a healthy young man?
This case report highlights acute myocarditis as a potential rare adverse effect following mRNA COVID-19 vaccination in young men, though the risk of cardiac involvement remains higher from COVID-19 infection itself.
The coronavirus disease 2019 (COVID-19) vaccination frequently leads to minor side-effects, that may be more intense after the second dose, but more serious side effects have been reported. We report a case of a 24-year-old man who presented to the hospital with acute substernal chest pain, 4 days after his second COVID-19 Moderna vaccination. Laboratory studies revealed elevated troponins and negative viral serologies. Cardiac magnetic resonance imaging (cMRI) demonstrated edema and delayed gadolinium enhancement of the left ventricle in a midmyocardial and epicardial distribution. The patient was diagnosed with myocarditis following Moderna vaccination. Our case report raises concern that myocarditis is a rare side effect of COVID-19 vaccine. Despite our report, it appears that there is a significantly higher risk of cardiac involvement from COVID-19 infection compared to COVID-19 vaccination.
Albert et al. (Tue,) conducted a case report in Myocarditis (n=1). Moderna COVID-19 vaccine was evaluated on Development of myocarditis. A 24-year-old man developed acute myocarditis, confirmed by elevated troponins and cardiac MRI, 4 days after receiving his second dose of the Moderna COVID-19 vaccine.
