Abstract

Purpose: Describe clinical characteristics, laboratory tests and cardiac magnetic resonance (CRM) imaging of patients with suspected acute myocarditis at Hanoi Medical University Hospital. Material and methods: Descriptive study conducted at Hanoi Medical University Hospital from June 2022 to June 2023 on patients clinically suspected of acute myocarditis, with laboratory tests and cardiac magnetic resonance imaging. Acute myocarditis was diagnosed based on expanded diagnostic criteria and the Lake-Louise 2009 criteria. Results: There were 7 patients with a mean age of 27.7±14.5; male accounts for 71.4%. The main clinical manifestations were chest pain and fever, accounting for 71.4% and 57.1%, respectively. Troponin T and CRPs increased in all patients. 57.1% of patients had abnormalities on the electrocardiogram. On MRI, 100% of patients showed signs of myocardial edema, the myocardial/striated muscle signal ratio ≥ 4 accounted for 71.4%, mainly in the anterior wall, lateral wall (100%), and septum (85.7%). There were 42.8% of patients with signs of early myocardial enhancement and 85.7% of patients with late myocardial enhancement. 71.4% of patients met the diagnostic criteria according to the Lake Louise 2009 criteria. After treatment, all patients recovered after 2-3 weeks. Conclusion: CRM imaging was an important non-invasive imaging method in diagnosing acute myocarditis with clinical symptoms and laboratory tests.
