The potassium-sparing diuretic spironolactone [Aldactone] prolongs survival and improves heart failure symptoms by which mechanism?
a. Blocking aldosterone receptors
b. Increasing diuresis
c. Reducing venous pressure
d. Reducing afterload
A
Spironolactone prolongs survival in patients with HF primarily by blocking receptors for aldos-terone. Spironolactone cause only minimal diuresis. It does not reduce afterload, and it does not reduce venous pressure enough to prolong survival, because it causes only minimal diuresis.
