Which diuretic regimen is listed for heart failure management?

• A. Mannitol
• B. Furosemide and Spironolactone
• C. Thiazide diuretics
• D. Acetazolamide

Answer: (B)

In heart failure, relieving fluid overload and improving outcomes hinges on effective diuresis. A loop diuretic like furosemide is the frontline choice because it acts quickly to promote natriuresis and diuresis, lowering preload and easing edema and shortness of breath. Adding spironolactone, an aldosterone antagonist, provides an important survival benefit in patients with reduced ejection fraction by blocking aldosterone-driven sodium retention and preventing further adverse remodeling, while also helping to counteract potassium loss from the loop diuretic. Together, they address both symptoms and longer-term outcomes, and this combination is widely supported by guidelines and trials. Mannitol is an osmotic diuretic used for specific acute situations (like intracranial pressure or certain renal contexts) rather than for chronic heart failure management. Thiazide diuretics can be useful as add-ons or in milder cases or when diuretic resistance is encountered, but they are not the primary regimen with mortality benefit in heart failure. Acetazolamide is not a standard HF diuretic and doesn’t provide the targeted benefits seen with loop diuretics plus an aldosterone antagonist.
