When should ARBs be used in HF management?

When should ARBs be used in HF management?

• A. For patients intolerant to ACE inhibitors due to cough or angioedema or when ACE inhibitors are contraindicated.
• B. For patients intolerant to diuretics.
• C. In place of beta-blockers.
• D. For acute myocardial infarction.

Answer: (B)

ARBs are used in heart failure mainly as an alternative when ACE inhibitors cannot be used. They provide similar benefits in reducing afterload and protecting the heart and kidneys, but without triggering the cough or angioedema that ACE inhibitors can cause. This makes ARBs the best choice for patients who develop ACE inhibitor–related side effects or have a contraindication to ACE inhibitors. They are not chosen because a patient cannot tolerate diuretics, since diuretics address fluid overload and symptom relief, while ARBs don’t replace that role. They also don’t replace beta-blockers, which have complementary mortality benefits in HF. ARBs aren’t the primary choice specifically for acute myocardial infarction, though they may be used in certain contexts, but the question centers on chronic HF management.
