COVID-19 Vaccine Associated Myopericarditis and Perimyocarditis
See also: CoVid-19 Vaccine Associated Myocarditis and CoVid-19 Vaccine Associated Pericarditis
Myopericarditis refers to inflammation of the pericardium and myocarditis. Myopericarditis is sometimes used interchangeably with perimyocarditis.
Myopericarditis is used when there are primarily pericarditis symptoms with evidence of the involvement of the myocardium as evidenced by cardiac biomarker elevation or imaging studies revealing normal wall motion. If there is evidence of regional wall motion abnormalities with reduced ventricular function, the term perimyocarditis has been used. Manda YR, Baradhi KM. Myopericarditis. [Updated 2021 Jul 26]
Summary from the CDC
- 2,574 reports of myopericarditis or pericarditis to VAERS (as of August 18, 2021)
- 1,903 myopericarditis, 671 pericarditis
- Epidemiology of myopericarditis following COVID-19 vaccination similar to previously reported updates
- Primarily in younger males, after dose 2 mRNA vaccination, symptom onset clustering within several days of vaccination
- Limited follow-up information in VAERS case reports suggests most patients (77%) recovered from symptoms at time of report or follow-up
- Observed vs. Expected analysis with VAERS reports
- Males: Observed > Expected in age groups through 49 years
- Females: Observed > Expected in age groups through 29 years
- Enhanced surveillance for myocarditis outcomes after mRNA COVID-19 vaccination in VAERS case reports is ongoing
