Abstract
In the aging heart a localized amyloid restricted to the atria frequently occurs. This amyloid is designated isolated atrial amyloid (IAA). In the atria a natriuretic hormone, known as atrial natriuretic peptide (ANP), is produced. In this study, we show that antisera to IAA and to ANP both stain atrial muscle cells and atrial amyloid. Furthermore, a small protein purified from IAA had an amino acid sequence identical to that of ANP.
