There are no specific treatment options for myocarditis, but rest, symptomatic and supportive therapy are generally the mainstays. The treatment of myocarditis is usually adjuvant supportive therapy, which is mainly related to the clinical manifestations of the patient. In patients who are generally asymptomatic or have mild symptoms, myocarditis can be recovered in about 1 week. Patients should reduce physical activity and rest, while symptomatic treatment can be given for upper respiratory tract infection symptoms such as fever, fatigue, muscle aches, or gastrointestinal symptoms such as nausea, vomiting, and diarrhea. Patients with cardiac symptoms often require hospitalization and symptomatic treatment according to the type of clinical symptoms, mainly including anti-arrhythmic and heart failure correction: some patients with arrhythmias can recover with short-term medication, while others may require long-term medication or pacemaker implantation; some patients with heart failure can recover to normal heart function, while others require long-term medication. Some patients with heart failure may recover to normal heart function, while others require long-term medication. Patients who experience shock or even sudden death need to be treated in the cardiac intensive care unit. In addition to this, immunomodulators, immunosuppressants, and antiviral treatments for viruses are also used in clinical practice, and some patients achieve better results. The treatment of myocarditis is currently symptomatic according to the patient’s condition. Patients with mild cases can recover through rest; patients with cardiac symptoms need to be hospitalized for symptomatic treatment; severe patients need to be closely monitored in the care unit for timely resuscitation.
