Radiologists, CDC warn of myocarditis in young adults after COVID-19 vaccination – Radiology Business

Radiologists and the U.S. Centers for Disease Control and Prevention are warning about rare instances of myocarditis after receiving the Moderna or Pfizer COVID-19 vaccines.

The CDC alerted healthcare professionals about the issue late last week. There have reportedly been several dozen cases of such inflammation of the heart muscle, typically within four days following the second dose. Those affected are primarily male young adults and adolescents, the agency noted.

In one recent example, Massachusetts imaging experts highlighted a 24-year-old man who presented with acute substernal chest pain four days after his second Moderna shot. Cardiac MRI with gadolinium enhancement helped confirm the diagnosis, they detailed May 18 in Radiology Case Reports.

The data in hand suggest a small risk of myocarditis following infection, as well as thrombosis-related myocardial infarction, ElisabethAlbert,MD, a cardiothoracic imaging fellow with UMass Memorial Medical Centers Department of Radiology, and co-authors concluded. Despite our report, it appears that there is a significantly higher risk of cardiac involvement from COVID-19 infection compared to COVID-19 vaccination. Accordingly, we believe that COVID-19 vaccination should remain the cornerstone for population immunity, they added.

The American Heart Association echoed those sentiments in its own May 23 alert, emphasizing that the benefits of vaccination enormously outweigh the rare risk of myocarditis. This inflammation of the middle layer of the wall of the organ can weaken the hearts muscle and electrical system. Severe myocarditis may lead to heart failure, abnormal heartbeat or sudden death, the association noted.
