Adolfo José de Bold (February 14, 1942October 22, 2021) was an Argentine-born Canadian cardiovascular researcher, best known for his discovery of atrial natriuretic peptide (ANP), a polypeptide hormone secreted by heart muscle cells. The hormone plays a role in regulating blood pressure, blood volume, and cardiovascular growth, and its discovery proved the endocrine function of the heart.
