近20多年来积累的临床和实验资料说明病毒感染与一些心脏疾病的发病有关。引起心肌炎的病毒种类很多,最重要的是柯萨奇B组病毒。通过病毒分离及血清学检查已证实柯萨奇B组1～5型病毒均与心肌炎有关。Lerner和Wilson建议将病毒与心肌炎的病因关系分为三级:①从心脏或心包液中分离出病毒或用免疫学方法证实病变部位 Nearly 20 years of accumulated clinical and experimental data shows that the virus infection and the incidence of some heart disease. Many types of viruses cause myocarditis, the most important is Coxsackie B virus. By virus isolation and serological tests have confirmed Coxsackie B group 1 to 5 viruses are associated with myocarditis. Lerner and Wilson suggest that the etiology of the virus and myocarditis is divided into three levels: ① from the heart or pericardial fluid isolated virus or immunological methods to confirm the lesion
