Immunohistochemical study on human atrial natriuretic polypeptide in the ventricle of hearts with endocardial fibroelastosis.

The presence and distribution of human atrial natriuretic polypeptide ( ANP) were investigated immunohistochemically in the ventricles of hearts of 14 cases with endocardial fibroelastosis and 15 cases with noncardiac disease in children. Paraffin sections of autopsied hearts with endocardial fibroelastosis were stained with polyclonal antibodies against human alpha- ANP. Immunoreactive myocytes were clearly demonstrated in the ventricles of 10 hearts with endocardial fibroelastosis. The distribution of ANP-positive cells was most frequent in the inner one-third of the left ventricle. No ANP immunoreactivity was detected in any heart in cases with noncardiac disease. The left ventricular volume index of hearts with ANP-positive cells was larger than that with ANP-negative cells. The mean diameter of ANP-positive myocytes was greater than that of ANP-negative myocytes. These results suggest that ANP expression in ventricular myocytes is related to severe dilatation of the ventricular cavity and to development of myocardial hypertrophy in endocardial fibroelastosis.[1]
