More than 50% of Persistent Myocardial Scarring at One Year in “Infarct-like” Acute Myocarditis Evaluated by CMR
Why the study?
Although CMR is a reference tool for non-invasive myocarditis diagnosis, its role in follow-up after the acute event remains unclear.
Population
174 patients with CMR-confirmed infarct-like acute myocarditis
Comparison
Persistent myocardial scarring vs complete recovery at one year on CMR

Implication
Persistent scarring at 1 year in >50% of cases warrants caution in risk assessment; leaves open optimal CMR follow-up timing and prognostic value.

Population
174 patients with infarct-like acute myocarditis confirmed by cardiac magnetic resonance (CMR)
O
Outcome
Persistent myocardial scarring on CMR at one yearsurrogate
More than half of patients with infarct-like acute myocarditis have persistent myocardial scarring at one year, which is associated with a higher frequency of ventricular dysrhythmias and can be predicted by initial peak troponin and LGE extent.
