Which hormone decreases cardiac output by decreasing blood volume and preload? which hormone decreases cardiac output by decreasing blood volume and preload? norepinephrine aldosterone atrial natriuretic peptide antidiuretic hormone?

Atrial natriuretic peptide is the hormone which decreases cardiac output by decreasing blood volume and preload.It is a peptide secreted by the cardiac atria responsible for promoting salt and water excretion and lowering the blood pressure.It is produced in response to renin-angiotensin whenever there is an increased blood volume and is a powerful vasodilator. The production of atrial natriuretic peptide is stimulated by the stretch of the atria and is antagonistic to aldosterone and angiotensin II.
