Abstract

The distribution of a group of enzymes was determined histochemically in the surgically resected auricular myocardium of 5 cases of rheumatic and 6 cases of congenital heart disease. The enzymes studied included succinic dehydrogenase, diphosphopyridine nucleotide diaphorase, adenosine triphosphatase (ATPase), glucose-6-phosphatase, alkaline and acid phosphatase, and nonspecific esterase. The only abnormality noted was the apparent marked reduction in ATPase activity in the myocardium.
