Myocarditis, especially acute myocarditis, is a common disease in children. The disease initially manifests with signs such as fever, headache, body aches, paleness...so it is often misdiagnosed with cases of common cold.

1. Myocarditis in children

Myocarditis is inflammation of the myocardium, necrosis or lysis of myocardium caused by infection, toxicity, or diseases of the connective tissues. Myocarditis in children is often accompanied by inflammation of the endocardium or pericarditis.

2. Causes of myocarditis in children

Among the causes of myocarditis, the leading ones are enteroviruses, echoviruses and adenoviruses. In addition, there are measles virus, mumps ... can also cause myocarditis.
When these agents enter the body, they will damage the heart muscle cells, reduce the contractility of the heart muscle, causing cardiovascular collapse. At this time, the heart must dilate and increase activity to ensure the activities of the body. However, due to overwork, the heart is weakened, the heart muscles contract very weakly, which is gradually destroyed, leading to the release of substances and elevated heart enzymes.
Myocarditis can occur at any age, including young children, especially children between the ages of 2 and 10. In children under 24 months, the disease is likely to occur because at this time, the child's body has not yet completed the functioning of the organ systems and the resistance is still weak.
Myocarditis is a dangerous disease, especially acute myocarditis. Clinically, it is possible that the pediatric patient only has transient myocarditis, after being treated and restored, there will be no sequelae. But in contrast, many severe cases, the risk of leaving complications of heart failure or arrhythmia even has a high risk of death.

On examination, a faint heart sound is a very valuable early symptom in acute myocarditis, initially with a faint first sound. Then fade for the second hour with signs of cyanosis, pale color, tachycardia, low blood pressure, especially the maximum blood pressure, chest pain, palpitations, shortness of breath when exerting, severe cases difficult. breathe even at rest. Cardiopulmonary auscultation can be seen galloping, systolic murmur at the apex of the heart due to left ventricular dilatation causing functional mitral regurgitation.
Signs of heart failure appear when inflammation of the heart muscle is widespread. Children appear more often chest pain, tachycardia or arrhythmia accompanied by shortness of breath during activity even at rest, may edema legs, ankles and feet due to fluid retention.
