What is the treatment for acute viral myocarditis

Acute viral myocarditis is also a type of viral myocarditis, and viral infection is also the main cause of acute viral myocarditis. Treatment of acute viral myocarditis must be timely to avoid worsening of the condition. At the same time, patients with acute viral myocarditis should also pay attention to rest.

1. General treatment

Hypoxia and exercise can increase the damage of the virus to the myocardium. Therefore, patients with myocarditis should emphasize bed rest in the early stages, and generally need to rest for about 3 months. Patients with enlarged heart or a history of heart failure should extend their rest time, and then gradually increase their activity level after their electrocardiogram and X-ray examinations return to normal. If you do not pay attention to rest in the early stages, it may cause progressive enlargement of the heart and bring more sequelae. At the same time, patients should eat foods that are easily digestible and rich in vitamins and proteins.

2. Antiviral treatment

The efficacy is uncertain. For myocarditis caused by influenza virus, morphine 100-200 mg, tid; amantadine 100 mg, tid can be tried. For herpes virus myocarditis, 50-100 mg of cytarabine can be tried by intravenous drip daily; 100 mg of ribavirin can be tried by intravenous drip daily if necessary. The course of treatment is generally 1 week. Some Chinese herbal medicines such as Isatis Root, Forsythia suspensa, Folium Isatidis, and Polygonum cuspidatum are also believed to be effective against viral infections, but there are individual differences and patients' responses to drugs are not the same.

3. Immunomodulators

In recent years, interferon and transfer factor have been proposed to prevent and treat myocarditis. There are also reports of intravenous immunoglobulin treatment of acute viral myocarditis.

4. Treatment of complications

The treatment of various arrhythmias and heart failure is basically the same as that caused by other causes. High-degree atrioventricular block, rapid ventricular heart rate or sinus node damage may cause syncope or hypotension and require electrical pacing or cardioversion. Most patients with third-degree atrioventricular block can recover after the acute phase with the help of a pacemaker. Caution is required when using digitalis drugs in heart failure. It is advisable to start with a small dose and increase the dose gradually to avoid toxic reactions.
