to elucidate the expression of the atrial natriuretic polypeptide ( anp ) gene in the ventricle of the human failing heart , we have measured anp and anp messenger rna ( anpmrna ) levels in left ventricular aneurysm obtained at operation , biopsy specimens of left ventricles from dilated cardiomyopathy ( dcm ) and autopsy samples of old myocardial infarction ( omi ) and dcm hearts , and compared the levels with those in the normal ventricle .
