Abstract
Endomyocardial biopsies (EMBs) of 47 patients with various cardiac disorders were analysed. Clinically 26 patients were diagnosed as having dilated cardiomyopathy (DCM), 9 myocarditis, six restrictive heart disease and six as Duchenne muscular dystrophy. EMB showed normal histological picture in six cases of DCM and findings consistent with DCM in rest of the twenty cases. None of these biopsies showed evidence of myocarditis. Diagnosis of myocarditis could be confirmed on EMB only in three out of nine clinically diagnosed cases. Cases with restrictive heart disease showed normal biopsy in two, infarction in one, findings consistent with endomyocardial fibrosis in one and amyloidosis in two cases. EMB on six cases of Duchenne muscular dystrophy showed nonspecific histological changes. To conclude, in this series, cases of DCM did not show evidence of underlying myocarditis in endomyocardial biopsies.
