Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This study will address the above-mentioned knowledge gaps by focusing on patients who have received at least one dose of a COVID-19 vaccine. The study will focus on cardiac blood and imaging biomarkers to facilitate early recognition of patients at risk for myocardial injury after COVID-19 vaccination. Ultimately, the intention is to identify patients at risk, reduce adverse events, and determine the need for longer-term follow-up in patients with myocardial injury after vaccination.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Cohort A - Symptomatic
Those with clinical findings suggestive of myocarditis/myocardial injury after COVID-19 vaccination
Cardiac PET/MRI
An imaging technique that combines the strengths of both MRI and PET into one comprehensive study. This technique allows for detailed myocardial tissue characterization with MRI (including assessment of myocardial edema and fibrosis) and metabolic changes (including myocardial inflammation).
Blood Biomarkers
Markers of cardiac damage, inflammation, circulating microRNA profiles, and COVID antibody levels will be evaluated in patients after COVID-19 vaccination.
Cohort B - Asymptomatic
Those without signs or symptoms suggestive of myocarditis after COVID-19 vaccination
Cardiac PET/MRI
An imaging technique that combines the strengths of both MRI and PET into one comprehensive study. This technique allows for detailed myocardial tissue characterization with MRI (including assessment of myocardial edema and fibrosis) and metabolic changes (including myocardial inflammation).
Blood Biomarkers
Markers of cardiac damage, inflammation, circulating microRNA profiles, and COVID antibody levels will be evaluated in patients after COVID-19 vaccination.
