1. Etiology 1. Myocarditis is a kind of restrictive or diffuse inflammation of myocardium, which can be primary in myocardium or part of systemic diseases. There are many factors that cause myocarditis, such as virus, bacteria, fungi, parasites, immune response, physical and chemical factors and so on. Viral myocarditis is the most common, and enterovirus, especially Coxsackie B virus infection is the most common.
2. Etiology 2. Bacterial diphtheria is the kiln pathogen that causes myocarditis, and hemolytic streptococcus is also the cause of this disease.
3. Etiology 3. Take the virus as an example. When the virus is infected, the virus enters the myocardial fibers from the blood through capillaries and perivascular stroma, and replicates in the endocardium of myocardial cells, causing inflammatory reactions such as myocardial cell lysis, necrosis, edema and monocyte infiltration. The late myocarditis may be caused by humoral immunity and cellular immunity induced by virus or myocardial antigen.
Matters needing attention
After the onset of myocarditis, don't have excessive mood swings in your daily life. You can exercise properly, but don't do strenuous exercise. We should also develop good living habits at ordinary times.
