Myocarditis refers to a disease characterized by local or diffuse inflammation of myocardium. According to Dallas standard, the histological evidence of myocardial infiltration is inflammatory infiltration, accompanied by degeneration and adjacent myocardial necrosis. Myocardial events are different, mainly depending on the degree and severity of injury. Some people may have no symptoms at all. Mild patients may have non-specific symptoms such as fever, cough and diarrhea, and severe patients may have severe arrhythmia, heart failure, cardiogenic shock and even death, so it is less likely to diagnose myocarditis only by clinical symptoms.

Patients with myocarditis caused by cold must first control the virus. Generally speaking, antiviral drugs can be used to control virus reproduction. Some patients may have antibacterial drugs to prevent myocardial degeneration caused by bacterial infection. The first is basic treatment, such as rest or moderate nutrition, to preserve physical strength, to rest the myocardium and to avoid overwork such as staying up late. Generally speaking, an enlarged heart can return to normal after a period of rest.

Viral cold causes myocarditis. Drugs are mainly supplied to myocardial cells. For example, polarized liquid and astragalus can be used to improve myocardial immunity. In addition to anti-virus and nourishing myocardium, a very important treatment for viral myocarditis is bed rest. Rest in milk is usually an important measure to treat viral myocarditis. If it's viral myocarditis, he needs to rest for three months. If there is no more standardized rest time, myocarditis may lead to serious development and aggravation, so effective treatment must be carried out under the guidance of doctors.

For patients with fulminant myocarditis, glucocorticoid and gamma globulin should be given as adjuvant therapy, and active anti-infection and antiviral therapy should be given at the same time. When the condition is serious, plasma and blood purification should be given. Myocarditis caused by freezing is mainly caused by virus infection. Patients with myocarditis are advised to stay, avoid emotional excitement or overwork, have a light and digestible diet and eat less cadmium.
