No immediate clinical implications; leaves open translation of atrial peptide mechanisms to human cardiorenal disease.
This preclinical study demonstrates that the natriuretic and diuretic effects of atriopeptins are closely correlated with their ability to induce renal vasodilation.
Wakitani et al. (1985) studied this question. Atrial peptides (atriopeptins) was evaluated on Renal blood flow, urine volume, sodium excretion, and osmotic clearance. Atrial peptides produced concentration-dependent increases in renal blood flow and sodium excretion, exhibiting a positive linear correlation between natriuresis and renal vasodilation.
