[Hypertrophic cardiomyopathy--examination findings, family histories and results of close examinations of a family in two autopsied cases].

A 55-year-old woman, who died immediately after getting an intramuscular injection of lincomycin for treatment of a cold, and a 14-year-old boy, who died suddenly while practicing soccer, were autopsied respectively and their disease was diagnosed as hypertrophic cardiomyopathy by characteristic pathological findings. Each family history was investigated. Especially, the latter case showed clearly a family line of hypertrophic cardiomyopathy. At the request of the family, his elder brother and mother were examined closely at the University Hospital. Their illness was diagnosed accurately as hypertrophic cardiomyopathy from their findings of electrocardiograms, echocardiograms and endomyocardial biopsies. They are now taking medications and guidances of a doctor as to physical activity and way of life as outpatients at the University Hospital.
