PG - 528-35 LID - 10.1093/rheumatology/kep426 [doi] AB - OBJECTIVE: To investigate the patterns of myocardial involvement in the presence of self-limiting and sustained systemic inflammation, using MRI. METHODS: Ninety-four subjects, with a clinical diagnosis of myocarditis (n = 36), RA (n = 24) and apparently healthy subjects (n = 34, control group), underwent standardized cardiac MRI protocol for the assessment of global and regional morphology and systolic function using balanced steady-state free precession sequences, T2-weighted images and late gadolinium enhancement (LGE) studies. RESULTS: The three groups were well matched for age, gender and cardiovascular risk factors. The RA group showed markedly increased end-diastolic volumes and reduced ejection fraction (P < 0.05). Antero/inferolateral wall thickness was greater in the myocarditis group and reduced in RA, associated with reduced radial and longitudinal thickening (P < 0.01), and markedly raised T2-oedema ratio and global LGE scores (P < 0.05). CONCLUSIONS: Our results may signify the phenotypic features of myocardial plasticity and deformation in response to self-limiting and sustained inflammatory injury.
