Which agents help restore organ perfusion and reduce congestion in heart failure?

• A. Diuretics
• B. Inotropic agents
• C. ACE inhibitors
• D. Digoxin

Answer: (B)

Low forward flow in heart failure reduces perfusion to organs and causes congestion from elevated pressures. The way to quickly improve organ perfusion is to boost the heart’s pumping strength. Inotropic agents increase the force of myocardial contraction, which raises stroke volume and cardiac output. With better forward flow, tissues receive more blood, improving perfusion, and the congestive backlog is eased as pressures normalize. Other options help in different ways but don’t restore perfusion as directly or rapidly. Diuretics mainly reduce fluid overload and edema, easing congestion without significantly increasing cardiac output. ACE inhibitors lower afterload and have long-term remodeling benefits, but their immediate impact on perfusion is modest. Digoxin can boost contractility, but it has a slower onset and is less reliable for rapid perfusion restoration in acute decompensation.
