病毒性心肌炎常突然发病,各种年龄均可受累,病变不仅侵犯心肌,尚可侵犯心包及心内膜。近年有人指出急性心肌炎可转变成慢性心肌病,故一旦发病则有可能危害终生,所以病毒性心肌炎日益受到重视。 Often a sudden onset of viral myocarditis, all ages can be involved, the lesion not only violates the myocardium, can still encroach on the pericardium and endocardium. In recent years, some people pointed out that acute myocarditis can be transformed into chronic cardiomyopathy, so once the disease may endanger the life, so viral myocarditis is increasingly valued.
