In 1981, de Bold et al. reported that the administration of atrial extracts to rats induced diuresis and natriuresis [1]. Soon afterwards, the substance with diuretic and natriuretic properties present in the atrial extracts was identified as the atrial natriuretic peptide (ANF) [2]. This important discovery led to the new concept that the heart was not only a mechanical pump but also an endocrine organ. Since the characterization of ANF, many reports appeared in the literature describing a wide spectrum of biological actions displayed by this peptide supported by the wide distribution of the receptors in
