Which antihypertensive combination is recommended post-myocardial infarction or in heart failure?

• A. ACE inhibitor with calcium channel blocker
• B. ARB with thiazide diuretic
• C. Beta-blocker with diuretic
• D. An ACE inhibitor or ARB combined with a beta-blocker

Answer: (D)

Blocking both the renin-angiotensin-aldosterone system and the sympathetic nervous system after a myocardial infarction or in heart failure improves survival and slows disease progression. An ACE inhibitor or ARB reduces angiotensin II–driven vasoconstriction, remodeling, and fluid retention, which helps both function and long-term outcomes. A beta-blocker counters the harmful effects of chronic sympathetic activation on the heart, lowers heart rate and myocardial oxygen demand, and reduces arrhythmia risk. Using these two strategies together provides complementary benefits that address the underlying disease processes, making this combination the recommended approach. Other pairings may control blood pressure or symptoms, but they don’t offer the same focused mortality and remodeling benefits in this setting.
