Purpose: The exact morbidity of myocarditis is unknown, as the treatment is generally
delayed in virtue of misdiagnosis or missed diagnosis. The aim of this study was to identify prognostic
factors of left-ventricular remodeling on CMRI performed in patients with pathological
Materials and Methods: Sixty-two cases with various presentations of myocarditis (39 cases with
heart failure; 23 cases with arrhythmias) were selected. All patients, who underwent coronary angiography,
endomyocardial biopsy, were divided into positive-remodeling and negativeremodelling
groups to analyse LGE and cardiac cine parameters at presentation and subsequent to
Result: Comparison of two subgroups in CMRI is as follows: positive LGE (65.6% vs. 86.7%;
p<0.05), LVEF (41.3±14.8% vs. 37.6±10.1%; p=0.62), (25.7±2.0% vs. 24.0±2.5%; p=0.81),
(44.5±3.9mm vs. 46.3±5.4mm; p=0.76), (129.1±8.5ml vs. 135.3±12.2ml; p=0.26), (74.8±7.3ml vs.
79.1±10.0ml; p=0.55), (52.0±5.7g vs. 49.6±6.5g; p=0.71), (34.9±3.5ml vs. 32.4±6.2ml; p=0.68),
(3.8±0.7L/min vs. 3.1±0.5L/min; p=0.64), (2.9±0.6L/min*m2 vs. 2.7±0.5L/min*m2; p=0.79).
Conclusion: LGE-MRI is rewarding as an independent predictor in left-ventricular positive and
negative remodelling of myocarditis.
