Correct answer: A — Replace spironolactone with eplerenone

A is correct. Eplerenone is a mineralocorticoid receptor antagonist with less anti-androgen effect and can preserve the MRA component when spironolactone causes gynaecomastia, subject to renal and potassium monitoring. B does not address the adverse effect. C may worsen systolic heart failure. D removes therapies with prognostic benefit. E neither treats the adverse effect nor provides an equivalent HFrEF regimen.
