It is possible to cure myocarditis completely, but a very small number of patients turn into chronic myocarditis due to untimely treatment, which can seriously lead to dilated cardiomyopathy. Myocarditis is an inflammatory lesion of the myocardium caused by a variety of pathogenic factors, mostly in young adults and mostly due to infectious factors, such as viruses like coxsackievirus and influenza virus, and bacteria like Corynebacterium diphtheriae and streptococcus, among which viral infections are common. The onset of myocarditis is usually preceded by prodromal discomfort, such as fever, sore throat, muscle aches, etc. After 1-3 weeks of infection, symptoms such as chest tightness, chest pain, arrhythmia, shock, etc. may occur, depending on the degree of infection. You can give myocardial nutrients, anti-arrhythmic drugs, anti-viral drugs and other hormone therapy if necessary.
