Myocarditis in children

Diseases such as myocarditis are a relatively serious inflammatory manifestation of the human body. Otherwise, the disease may worsen seriously due to the different extent of myocardial lesions or the severity of the disease. Especially in children, mild cases of myocarditis may have no clinical symptoms, but severe cases may lead to sudden death.

Pediatric myocarditis is a very common heart disease in children. Myocarditis refers to local or diffuse inflammatory lesions in the myocardium. When this type of pediatric myocarditis occurs, the patient's physical characteristics are mainly interstitial inflammatory cell infiltration, and even some serious myocardial necrosis. If not treated promptly, inflammation will still affect the myocardial cells, interstitial tissue, and even vascular components and pericardium.

Myocarditis in children can be caused by infectious and other causes. Infectious myocarditis includes viral, bacterial, rickettsial, spirochetal, fungal and parasitic infections, among which viral myocarditis is the most common. The severity of the disease varies. Severe cases may lead to death from acute heart failure and arrhythmia. Mild cases have no obvious symptoms and are not discovered until the chronic stage when dilated cardiomyopathy forms.

The common viruses that can cause viral myocarditis are adenovirus (especially serotypes 2 and 5) and enterovirus (coxsackievirus A and B groups, echovirus, poliovirus), among which coxsackievirus group B (CVB) is the most common. Other viruses that can cause viral myocarditis include: herpes simplex virus, varicella and herpes zoster virus, cytomegalovirus, rubella virus, mumps virus, hepatitis C virus, dengue virus, yellow fever virus, rabies virus, respiratory enterovirus, etc.

Myocarditis in children varies in severity. Severe cases may die from acute heart failure or arrhythmia. Mild cases may not have obvious symptoms, but if not treated in time, the harm caused can be unimaginable. I hope we can detect the disease in time and treat it early.
