Which class of medication is used in heart failure to decrease afterload and fluid overload?

• A. Beta blockers
• B. ACE inhibitors
• C. Diuretics
• D. Angiotensin Receptor Blockers

Answer: (D)

In heart failure, lowering the resistance the heart has to pump against (afterload) and reducing fluid overload both help improve cardiac output and symptoms. Angiotensin II receptor blockers work by blocking the AT1 receptor, which leads to vasodilation and a decrease in systemic vascular resistance. That directly lowers afterload. They also lessen aldosterone-driven sodium and water retention, which helps reduce fluid overload and edema. This dual action makes ARBs a good choice for addressing both driving pressures on the heart and congestion. Diuretics mainly target fluid overload by increasing urine output, but they don’t directly reduce the heart’s afterload. Beta blockers help with long-term outcomes through remodeling and heart rate control, but their primary effect isn’t to decrease afterload or edema. ACE inhibitors would have a similar benefit by lowering afterload and fluid retention, but ARBs are often favored in patients who can’t tolerate ACE inhibitors due to cough or angioedema.
