Heart-Scarring Detected Over 1 Year After COVID-19 Vaccination

Heart scarring was detected more than one year after COVID-19 vaccination in some people who suffered myocarditis following receipt of a shot, researchers reported in new studies.

A third of 60 patients with follow-up cardiac imaging done more than 12 months after their myocarditis diagnosis had persistent late gadolinium enhancement (LGE), which is, in the majority of cases, reflective of heart scarring, Australian researchers reported in a preprint of a new study, published on March 22.

Limitations of the paper, which was published ahead of peer review, included possible selection bias, since participation in the study was voluntary. Authors listed no conflicts of interest or funding.
