Myocarditis refers to inflammatory lesions of the myocardium caused by various reasons. Various factors such as infection, physical and chemical factors can cause myocarditis. The severity of the myocardial damage caused varies greatly, and the clinical manifestations are different. Mild patients have no symptoms, while severe patients may suffer from heart failure, cardiogenic shock and even sudden death. Most patients can recover after treatment, but some patients develop dilated cardiomyopathy after the acute phase and may suffer from recurrent heart failure.

Myocarditis can occur in people of all ages, but is more common in young and middle-aged people. For myocarditis caused by infectious reasons, there are often symptoms of primary infection first. For example, viral ones often have fever, sore throat, cough, vomiting, diarrhea, muscle aches, etc. Most of the symptoms of myocarditis appear 1 to 3 weeks after the viral infection. Regardless of the cause of myocarditis, the clinical symptoms of myocarditis are related to the characteristics of myocardial damage. For example, patients with arrhythmia as the main manifestation may experience palpitations, and severe cases may have blackouts and syncope; patients with heart failure as the main manifestation may experience various symptoms of heart failure such as dyspnea; severe cases may develop cardiogenic shock and related manifestations of shock; if the inflammation involves the pericardium and pleura, symptoms of chest tightness and chest pain may occur; some patients may also have manifestations similar to angina pectoris. Common physical signs include sinus tachycardia that is not parallel to body temperature, sinus bradycardia and various arrhythmias may also occur. Heart border enlargement accounts for 1/3 to 1/2 of patients, which is seen in severe myocarditis. Heart enlargement can cause mitral or tricuspid valve regurgitation, systolic murmur at the apex or left lower edge of the sternum, diastolic gallop rhythm and weakened first heart sound may be heard in patients with severe myocardial damage or heart failure, pericardial friction sound may be heard in patients with pericarditis, and mild cases may be completely asymptomatic and sudden death may occur.
