Heart failure & cardiomyopathies
Diagnostic accuracy, clinical characteristics, and prognostic differences of patients with acute myocarditis according to inclusion criteria
Authors' conclusion
ICD-10 codes have poor accuracy in identification of AM cases and should be used with caution in clinical research.
Study context
- Population
- Admissions with ICD-10 codes for acute myocarditis (AM), two hospitals
- Participants
- 291 unique admissions
- Comparison
- ICD-10 codes vs cardiac magnetic resonance (CMR)-confirmed or clinically suspected AM
- Outcome
- Diagnostic accuracy of ICD-10 codes for AM
Methodological detailstwo hospitals, literature review
- Two hospitals
- Literature review

Further findings
All-cause mortality, CMR-confirmed or CS-AM vs refuted diagnosis
- Lower all-cause mortality with CMR-confirmed or CS-AM than refuted diagnosis
- P = 0.019
CMR-confirmed vs CS-AM: demographics, comorbidities, survival · median follow-up 52 months
- Similar demographics, comorbidity profiles and survival
- P = 0.72
Literature review: outcomes by inclusion criteria
- Outcomes favourable in CMR-confirmed studies vs endomyocardial biopsy-confirmed AM studies
