Which treatment approach is specifically mentioned for right-sided heart failure?

• A. Insulin therapy
• B. Medications like Enalapril and oxygen therapy
• C. High-intensity exercise only
• D. Immunotherapy

Answer: (B)

Right-sided heart failure is managed by improving the heart's pumping efficiency and ensuring adequate oxygen delivery to tissues. An ACE inhibitor like enalapril helps by reducing afterload, which eases the work the right ventricle must do and can improve forward flow and symptoms. Oxygen therapy addresses hypoxemia that often accompanies heart failure, helping to improve oxygen delivery to tissues and relieve breathlessness. The other options don’t fit as standard treatments for this condition: insulin therapy targets diabetes, not heart failure; relying on high-intensity exercise alone is not a treatment and can be unsafe; and immunotherapy is not used for heart failure.
