病毒性心肌炎(viral myocarditis,VMC)是由嗜心肌病毒感染所致的以心肌炎症病变为主的疾病,儿童发病率较高,并有增加趋势。VMC发病机制未明且临床缺乏有效的治疗方法,部分心肌炎患者因病毒反复、持续感染而导致慢性心肌纤维化,最终演变为扩张型心肌病(dilated cardiomyopathy,DCM)、心力衰竭直至死亡。现多将VMC分为3期即病毒复制期、免疫反应期和期[1]。目前,普遍认为病毒感染心
Viral myocarditis (viral myocarditis, VMC) is caused by the myocarditis virus myocarditis disease-based disease, children have a higher incidence, and an increasing trend. VMC pathogenesis is unknown and the clinical lack of effective treatment, some myocarditis due to repeated viral infections, persistent infection led to chronic myocardial fibrosis, and eventually evolved into dilated cardiomyopathy (dilated cardiomyopathy, DCM), heart failure until death. VMC now divided into three phases that is the virus replication period and immune response period [1]. At present, it is generally believed that the virus infects the heart
