Key result
ProANP 31-67 shows therapeutic potential for cardiorenal disease and HF via potent diuretic and natriuretic properties.
Why the study?
ProANP 31-67 has unique potent and prolonged diuretic and natriuretic properties, prompting an evaluation of its actions and potential as a therapeutic strategy for cardiorenal disease and related end-organ damage.
proANP31-67 is a promising novel therapeutic target for heart failure and cardiorenal diseases due to its unique renal and cardiac protective effects.

May warrant randomized trials of proANP 31-67 in heart failure; leaves its therapeutic role open.
The characterization of the cardiac hormone atrial natriuretic peptide (ANP 9 9 – 1 26 ), synthesized and secreted predominantly by atrial myocytes under stimulation by mechanical stretch, has established the heart as an endocrine organ with potent natriuretic, diuretic, and vasodilating actions. Three additional distinct polypeptides resulting from proteolytic cleavage of proANP have been identified in the circulation in humans. The mid-sequence proANP fragment 31–67 (also known as proANP 3 1 – 6 7 ) has unique potent and prolonged diuretic and natriuretic properties. In this review, we report the main effects of this circulating hormone in different tissues and organs, and its mechanisms of actions. We further highlight recent evidence on the cardiorenal protective actions of chronic supplementation of synthetic proANP 3 1 – 6 7 in preclinical models of cardiorenal disease. Finally, we evaluate the use of proANP 3 1 – 6 7 as a new therapeutic strategy to repair end-organ damage secondary to hypertension, diabetes mellitus, renal diseases, obesity, heart failure, and other morbidities that can lead to impaired cardiac function and structure.
