Abstract

Purpose
We evaluated the clinical characteristics of patients undergoing cardiac magnetic resonance (CMR) examinations over 10 years at a tertiary referral hospital.
Methods
This retrospective study included 11,087 CMR examinations performed between November 2009 and September 2020. The number of adults aged ≥20 years was 10,648 (72.8% males). A total of 439 children or young adults aged < 20 years underwent CMR (66.5% males). Indications for CMR examinations were classified according to the Consensus Panel recommendations of the Society for Cardiovascular Magnetic Resonance (SCMR).
Results
The mean age was 55.9±12.4 years for adults. Forty percent of patients were obese. Leading cardiovascular risk factors were hypertension, dyslipidemia, diabetes mellitus, and current smoking status in 28.2%, 19.1%, 13.8%, and 25.4% of patients, respectively. The proportion of stress CMR examinations performed was 57.2%. For children, the mean age was 12.6±5.3 years. Most children underwent a non-stress CMR test. In adults without congenital heart disease, indication numbers for SCMR classes were 5,682 for class I (49.4%), 772 for class II (6.7%), 313 for class III (0.3%), and 4,714 for investigational group (41.1%). In pediatric patients and adults with congenital heart disease, indication numbers for SCMR classes were 539 for class I (80.3%), 62 for class II (9.2%), and 70 for the investigational group (10.4%).
Conclusion
CMR is most commonly performed in men in their 50s or 60s. CMR may be used as the first-line imaging technique (SCMR class I) in around a half of adult patients and in most pediatric patients.
