MedPageToday People with postvaccine myocarditis did not share the typical mid-term complications associated with conventional myocarditis, based on a population-based study from France.
With 18-month follow-up of people who had been hospitalized for myocarditis during the COVID-19 pandemic, it appeared that composite clinical outcomes were more favorable if people had developed myocarditis soon after COVID-19 mRNA vaccination rather than conventional myocarditis (weighted HR 0.55, 95% CI 0.36-0.86).
Meanwhile, the risk of poor composite outcomes — counting hospital readmission for myopericarditis, other cardiovascular events, and all-cause death — was comparable between post-COVID-19 myocarditis and conventional myocarditis groups (weighted HR 1.04, 95% CI 0.70-1.52), according to Laura Semenzato, MSc, a statistician at Saint-Denis Cedex France in Paris, and colleagues.
