Is COVID vaccine induced myocarditis temporary?
Mainstream news sources, like ABC News, assure us that COVID-19 vaccine induced myocarditis is only temporary: “they do come with temporary side effects and the rare risk of temporary heart inflammation called myocarditis among young men”. Source.
From a recent article on a cohort of adolescents with post COVID-19 mRNA vaccine myopericarditis published in The Journal of Pediatrics: “In classical myocarditis LGE can be predictive of a poor outcome. … Sixteen patients who had both acute phase and follow-up CMR available for review comprised the final cohort. … All patients underwent follow up CMR at 3-8 months after their initial study… Eleven patients (68.8%) had persistent LGE… GLS% remained abnormal in most patients… Four patients complained of intermittent chest pain at follow up with no identifiable abnormality on evaluation… we demonstrated persistence of abnormal findings on CMR at follow up in most patients… The presence of LGE is an indicator of cardiac injury and fibrosis and has been strongly associated with worse prognosis in patients with classical acute myocarditis. In a meta-analysis including 8 studies, Yang et al found that presence of LGE is a predictor of all cause death, cardiovascular death, cardiac transplant, rehospitalization, recurrent acute myocarditis and requirement for mechanical circulatory support. Similarly, Georgiopoulos et al found presence and extent of LGE to be a significant predictor of adverse cardiac outcomes in an 11 study meta-analysis. … In a cohort of adolescents with COVID-19 mRNA vaccine-related myopericarditis, a large portion have persistent LGE abnormalities, raising concerns for potential longer-term effects.” Source.
Okay then.
