Study Notes
Myocarditis Overview
- Myocarditis is an inflammatory disease of the myocardium, the heart muscle.
Causes of Myocarditis in Children
- Common causes of myocarditis in children include viral infections, specifically:
- Coxsackievirus
- Adenovirus
- Parvovirus
- Influenza virus
- Epstein-Barr virus
- Note: Enterovirus is NOT commonly involved in causing myocarditis in children.
Innate Immune Response
- The innate immune response in myocarditis can be activated by:
- Recognition of viral pathogen-associated molecular patterns (PAMPs)
- Activation of pattern recognition receptors (PRRs)
Coxsackie-Adenovirus Receptor
- The Coxsackie-adenovirus receptor (CAR) plays a crucial role in myocarditis pathogenesis by:
- Facilitating viral entry into cardiac cells
- Mediating viral-induced inflammation and cardiac damage
