好酸球浸潤を示した家族発症拡張型心筋症の1剖検例

Abstract

A 52-year-old male was admitted to our hospital in 1981 for evaluation of cardiomegaly and bradycardia. A permanent pacemaker was implanted for complete A-V block with bradycardia and myocardial biopsy was performed for diagnosis of his cardiac disorder ; he was diagnosed as having idiopathic dilated cardiomyopathy in l982. His older brother and younger brother were also diagnosed as having dilated cardiomyopathy. He died from congestive heart failure in 1993. The autopsy revealed infiltration of eosinophil in perimyocardial fibrosis. We think that infiltration of eosinophil in perimyocardial fibrosis might have affected this patient's cardiac function.
