Abstract
SAENZ-PENAS, Alejandra and FRIAS-ORDONEZ, Juan Sebastián. Miocarditis inducida por vacuna COVID-19 Spikevax - sospecha temprana para un manejo exitoso: reporte de caso. Revista médica Risaralda [online]. 2023, vol.29, n.2, pp.163-170. Epub Apr 08, 2024. ISSN 0122-0667. https://doi.org/10.22517/25395203.25325.
Introduction:
mass vaccination has been carried out worldwide to control the spread of COVID-19 infection, with the most commonly used vaccines being Pfizer-BioNTech and Moderna. Myocarditis after COVID-19 vaccination by Spikevax vaccine (previously known as Moderna vaccine) is an infrequent entity, that we still know more about the clinical picture and characteristics, and that little is known about long-term follow-up beyond 90 days.
Case report:
21-year-old male, college student, with no known previous history, presented with acute onset of oppressive central thoracic pain. It had an abrupt onset, in-crescendo course, associated with dyspnea and chills. Anti-inflammatory treatment with colchicine 0.5mg every 12 hours was started, and symptoms resolved within 24 hours of starting anti-inflammatory medication. The diagnosis of myocarditis was confirmed by cardiac magnetic resonance imaging and follow-up imaging showed resolution of the condition. The patient remained asymptomatic, and he was discharged early. His 90-day follow-up showed no residual sequelae.
Conclusions:
myocarditis following COVID-19 vaccination is predominantly seen in young males within days after vaccination. The pathophysiology of myocarditis is not yet well understood. Cardiac troponin I kinetics in the case presented, associated with the initial symptoms and cardiac imaging confirmed the presence and subsequent resolution of myocarditis. The prognosis is good and early suspicion is required.
