Physiological antagonist of aldosterone – MCQ – Answer

Which of the following acts as a physiological antagonist of aldosterone in heart failure? Correct answer: c) Atrial natriuretic peptide

Aldosterone causes salt and water retention in heart failure. It is part of the renin-angiotensin-aldosterone axis. Atrial natriuretic peptide is released in response to atrial stretch in heart failure. It produces diuresis and loss of fluid, partially ameliorating the effect of aldosterone and hence acts as a physiological antagonist.
