Study description

This is a non-interventional, retrospective case-control genetic association study using secondary data from the US-based Helix Research Network (HRN) Myocarditis Registry, where patients with myocarditis (cases) and patients without myocarditis (controls) will be identified. Cases and controls will be individuals who previously consented to participate in genetic research studies and for whom clinical information is available.
The study will include the below three cohorts of cases.
• Cohort A – post-mRNA COVID-19 vaccination myocarditis cases: myocarditis within 14 days of mRNA vaccination
• Cohort B – post-SARS-CoV-2 infection myocarditis cases: myocarditis within 8 weeks of SARS-CoV-2 infection
• Cohort C – acute/viral myocarditis cases: myocarditis unrelated to COVID-19 vaccination or SARS-CoV-2 infection
Controls will be individuals without myocarditis who previously consented to participate in the HRN.
