Cohort study
Myocardial Injury on Cardiac Magnetic Resonance (CMR) in Patients With COVID-19 and Suspected Cardiac Involvement
- Retrospective cohort study
- multicentre
- 18 international sites
Authors' conclusion
In this multicenter study of patients with COVID-19 with clinical suspicion for cardiac involvement referred for CMR, nonischemic and ischemic patterns were frequent when cardiac symptoms, ECG abnormalities, and cardiac biomarker elevations were present.
Study context

- Patients with PCR-confirmed COVID-19 and suspected cardiac involvement referred for CMR
- Participants
- 1,047 patients
- Outcome
- Myocardial injury patterns on CMR (acute myocarditis, nonacute/nonischemic, acute ischemic, nonacute/ischemic)
