Myocarditis

Incidence of myocarditis/pericarditis among veterans was low across more than 10 million doses of messenger RNA COVID-19 vaccines, given as a primary or booster dose, administered at the Veterans Health Administration, researchers found.

A modified version of the International Cardio-Oncology Society definition of immune checkpoint inhibitor-associated myocarditis may improve its predictive value, researchers reported.

Researchers identified the presence of circulating spike protein that evaded antibody recognition in adolescents and young adults who present with myocarditis after SARS-CoV-2 messenger RNA vaccination.

Most patients with cancer diagnosed with myocarditis after receiving immune checkpoint inhibitors showed evidence of liver dysfunction and muscle degradation, results of an observational cohort study in JACC CardioOncology showed.

Early data from a phase 2/3 trial suggest that the new Pfizer and BioNTech omicron booster increases protective antibodies against the BA.5 subvariant in adults 7 days after administration.

Myocarditis and pericarditis after COVID-19 vaccination is rare across demographic groups and most likely to occur in teen boys in the week after their second shot of a two-dose vaccine, according to a study.

Data from a large cohort in England suggest that risk for myocarditis, while small overall, is significantly higher after SARS-CoV-2 infection in unvaccinated individuals vs. after COVID-19 vaccination, researchers reported.

PHILADELPHIA — The CV complications of COVID-19 are wide-ranging, and the consequences can be especially serious in patients with HF, a speaker said at the Heart in Diabetes CME conference.

The American College of Cardiology and American Heart Association released a joint report detailing both CV and non-CV complications of COVID-19 as well as the respective diagnosis and treatment options.

A literature review shows COVID‐19 vaccine‐associated myocarditis is most common in adolescent boys presenting with chest pain 3 to 4 days after a second dose; however, the incidence is rare and carries good prognosis, researchers reported.
