  • Introduction: Myocarditis is an inflammation of the heart muscle often triggered by viral infections in young adults.

  • Epidemiology: Most commonly affects males under 40, often following recent viral illness.

  • Etiology: Frequently caused by viral pathogens like Coxsackievirus, Adenovirus, or Influenza.

  • Pathophysiology: Viral infection triggers immune response causing myocardial cell injury and inflammation.

  • Clinical Presentation: Symptoms include chest pain, fatigue, palpitations, and shortness of breath.

  • Diagnostic Evaluation: ECG changes, elevated cardiac enzymes, and cardiac MRI help confirm diagnosis.

  • Management: Supportive care, anti-inflammatory therapy, and treatment of heart failure if present.

  • Conclusion: Early recognition and treatment of post-infectious myocarditis in young adults improve outcomes.
