Key result
Among 7 patients identified with acute myocarditis over a 3-month period, 4 had received a second dose of an mRNA COVID-19 vaccine within the preceding 5 days.
Why the study?
It was unknown whether COVID-19 vaccination was linked to the occurrence of myocarditis.
Is mRNA COVID-19 vaccination associated with the occurrence of acute myocarditis?
Observational (n=7)
No
Is mRNA COVID-19 vaccination associated with the occurrence of acute myocarditis?
This case series provides early observational evidence of a potential association between mRNA COVID-19 vaccination and acute myocarditis, characterized by typical cardiovascular magnetic resonance imaging findings.
No takes yet. Share an insight, caveat, or question.
Should not change vaccination practice; hypothesis-generating for mRNA vaccine-associated myocarditis needing controlled confirmation.
Kim et al. (2021) conducted an observational in Acute myocarditis (n=7). mRNA COVID-19 vaccine was evaluated on Occurrence of acute myocarditis by cardiovascular magnetic resonance imaging. Among 7 patients identified with acute myocarditis over a 3-month period, 4 had received a second dose of an mRNA COVID-19 vaccine within the preceding 5 days.
