Introduction The study sought to evaluate indications for, image quality, safety and impact on patient management of cardiac MRI (CMR) in a district general hospital setting. In our analysis, the same variables as the EuroCMR Registry (Bruder et al. Journal of Cardiovascular Magnetic Resonance 2013;15:9) were assessed. To our knowledge, this is the largest single centre study of the routine use of CMR in a district general hospital setting.
Methods The database was developed using retrospective analysis of patient records from the start of the local CMR service in January 2014 till January 2017. All 791 consecutive patients were included in the dataset.
Results The most important indications were the investigation of myocarditis/cardiomyopathies (54.5%), work-up of suspected CAD/Ischemia (27.1%), and assessment of viability (9.1%). Image quality was diagnostic in 99.9% of cases. Mild adverse effects were reported for 3.8% of patients for stress CMR and in 1.1% of non-stress CMR. No serious adverse events were reported in this study population. In 26.5% of cases, CMR findings resulted in therapeutic modifications. In nearly 18.1% the final diagnosis based on CMR was different to that suspected before the CMR. These figures were different to those reported in the EuroCMR registry where therapeutic consequences were recorded in a higher proportion (53.4%) but new diagnoses recorded in a lower proportion (8.7%). The differences may be accounted for by differences in the study population and in data collection methods.
Conclusion The findings of this study reiterate the EuroCMR registry’s assertion that CMR is a safe procedure with a very high diagnostic image quality. CMR outcomes can be demonstrated to have considerable impact on diagnosis and patient management.
