1947年Gore和Saphir报告的1420例心肌炎中,风湿性和白喉引起的心肌炎仅占10％,增加了人们对病毒性心肌炎的注意。近十年来,其发病率逐渐增高,成为青、中年人的常见心脏病之一。关于诊断问题,因出现心脏症状时,病毒血症多不存在,不易分离病毒,加之国内多数医院受实验室条件限制,血清补体结合,病毒中和及血球凝集抗体试验尚未普及,故目前仍以排除诊断为主;其次,该病病理改变轻重悬殊,临床改变各异,可分为无症状型、心律失常型、心力衰竭型,心肌坏死型,心脏增大型和猝死型,亦给诊断带来困难,因此强调鉴别
Of the 1420 cases of myocarditis reported by Gore and Saphir in 1947, rheumatic and diphtheria-induced myocarditis accounted for only 10%, raising the awareness of viral myocarditis. In the past ten years, its incidence has gradually increased, becoming one of the common heart diseases of middle-aged and young people. On the diagnosis, due to the emergence of cardiac symptoms, viremia and more non-existent, difficult to isolate the virus, coupled with the majority of domestic hospitals by laboratory conditions, serum complement fixation, virus neutralization and hemagglutination antibody test has not yet spread, it is still Second, the pathological changes of the severity of the disease disparities, clinical changes can be divided into asymptomatic, arrhythmia, heart failure, myocardial necrosis, cardiac enlargement and sudden death, but also to the diagnosis brought Difficulties, so emphasis on identification
