BACKGROUND: Cardiac involvement in Takayasu arteritis (TA) is the major cause of morbidity and mortality. Cardiovascular magnetic resonance (CMR) is an excellent modality for the assessment of myocardial involvement. Studies have shown myocardial involvement in 25%-27% of patients. OBJECTIVES: To evaluate the prevalence and pattern of myocardial involvement in TA on CMR. We also evaluated any correlation between CMR changes and disease activity score (ITAS 2010 and ITAS-A) assessed at the time of CMR. METHODS: Patients classified as Takayasu arteritis according to Sharma et al. criteria were enrolled in the study. Demographic, clinical, and laboratory data were documented in the predesigned proforma. CMR was performed on a dedicated cardiac 3Tesla MR machine. Disease activity was recorded by ITAS2010 and ITAS-A. RESULTS: A total of 37 TA patients were included. Mean (+/-SD) age was 29+/-11 years. Female to male ratio was 3:1. Five patients (14%) had myocardial involvement on CMR. Two (2/5) had myocarditis and three (3/5) patients had features of ischaemic myocardial fibrosis. CONCLUSION: The myocardium is affected in TA, however the prevalence of subclinical myocardial involvement in our study was less (8% vs. 25%-27%) compared to the previous studies. Myocardial involvement trends towards early age of onset, less disease duration, lack of classical risk factors, and more with disease activity.
