The incidence of sudden death in idiopathic cardiomyopathy was analyzed based on a multi-center study in Japan, and possible prevention was discussed. Among 540 cases reported from 15 institutions, sudden death was most frequent in congestive or dilated type (19 cases, 22% of 87 deaths) and the ratio of sudden death to all deaths was high in the hypertrophic nonobstructive type (7 cases, 54% of 13 deaths) or the hypertrophic obstructive type (5 cases, 45% of 11 deaths). In the latter 2 types, the occurrence of sudden death seemed to be more related to exercise than in the congestive type. In the analysis of 4 sudden deaths among patients in congestive type, sudden death occurred in relatively asymptomatic patients after recovery from acute congestive heart failure. For the effective prevention, detection of undiagnosed patients by electrocardiographic screening, education of patients to avoid unprepared exercise, evaluation of physical tolerance by exercise testing and need for official registration of victims were discussed.
基于日本的一项多中心研究，对特发性心肌病的猝死发生率进行了分析，并探讨了可能的预防措施。在15家机构报告的540例病例中，猝死在充血性或扩张型中最为常见（19例，占87例死亡的22%），肥厚性非梗阻型（7例，占13例死亡的54%）或肥厚性梗阻型（5例，占11例死亡的45%）中猝死与所有死亡的比例较高。在后两种类型中，猝死的发生似乎比充血性类型更与运动有关。在对充血性类型患者中的4例猝死进行分析时，猝死发生在急性充血性心力衰竭恢复后相对无症状的患者中。为了有效预防，讨论了通过心电图筛查发现未确诊患者、教育患者避免无准备的运动、通过运动试验评估身体耐受性以及对受害者进行官方登记的必要性。
