From the Guidelines

Preventing viral myocarditis in children primarily involves good hygiene practices, avoiding exposure to viruses, and ensuring they receive all recommended vaccinations, as supported by the most recent evidence from 1. The key strategies to prevent viral myocarditis include:

  • Washing hands frequently with soap and water for at least 20 seconds, especially before eating and after using the bathroom
  • Avoiding close contact with people who are sick
  • Not sharing personal items like cups or utensils
  • Keeping children home when they're ill to prevent spreading infections
  • Maintaining a healthy lifestyle with nutritious food, adequate sleep, and regular physical activity to support a strong immune system It's also crucial to note that COVID-19 vaccination is associated with a very favorable benefit-to-risk ratio for all age and sex groups evaluated thus far, as stated in 1. Additionally, if a child develops symptoms like chest pain, unusual fatigue, shortness of breath, or irregular heartbeat, especially after a recent viral illness, seeking medical attention promptly is essential, as early detection and treatment of viral infections may help reduce the risk of complications like myocarditis, as implied by the guidelines in 1 and 1. It's worth mentioning that there are no specific medications or supplements proven to prevent viral myocarditis, and antibiotics are not effective against viral infections, as noted in the recommendations from 1. Overall, the prevention of viral myocarditis in children relies on a combination of hygiene practices, vaccination, and a healthy lifestyle, with prompt medical attention if symptoms arise, as supported by the latest evidence from 1.

From the Research

Prevention of Viral Myocarditis in Children

There are no specific methods mentioned in the provided studies to prevent viral myocarditis in children. However, some general information about the disease can be found:

  • Viral infections are the most common cause of myocarditis in children 2, 3, 4, 5, 6.
  • The disease can be asymptomatic or present with symptoms such as cardiac insufficiency, arrhythmias, and sudden death 4.
  • Diagnosis requires clinical suspicion, laboratory, and imaging studies 4, 5.
  • Treatment is mainly supportive, with a focus on supporting cardiac function and providing rest for the stressed cardiac muscle 3.

Risk Factors and Causes

Some potential risk factors and causes of viral myocarditis in children include:

  • Preceding viral infection 2, 3, 4, 5, 6.
  • Immune or autoimmune reaction triggered or maintained by an infection 4.
  • Systemic autoimmune disease 4.
  • Viral persistence, which may produce an autoimmune response to cardiac myosin 3.
  • Viral invasion of vascular endothelium causing vascular spasm with reperfusion injury 3.

Diagnostic and Treatment Options

Diagnostic and treatment options for viral myocarditis in children include:

  • Cardiac magnetic resonance imaging (CMR) to detect interstitial edema and assess subepicardial or mid-myocardial fibrosis 5.
  • Endomyocardial biopsy as the gold standard diagnostic test 2.
  • Supportive treatment with inotropic and afterload-producing agents to support cardiac function 3.
  • Anti-inflammatory, immunosuppressing, and anti-viral therapy, although their role is debatable 2, 6.
