What is the treatment for right-sided heart failure?

• A. Physical therapy only
• B. Antibiotics only
• C. Medications like Enalapril and oxygen therapy
• D. Lifestyle modification only

Answer: (C)

Right-sided heart failure is driven by venous congestion and reduced pumping effectiveness, so treatment aims to ease the heart’s workload and improve oxygen delivery. Enalapril, an ACE inhibitor, lowers systemic vascular resistance and afterload. By making it easier for the heart to pump, it can help improve forward flow and reduce venous pressures, which helps relieve symptoms and slow progression when used as part of comprehensive heart failure therapy. Oxygen therapy addresses low blood oxygen levels that often accompany right-sided failure, especially when lung disease or pulmonary hypertension is involved. Improving oxygenation also reduces pulmonary vasoconstriction and supports overall tissue oxygen delivery, which helps the failing heart function better.

Other options focus on a single aspect and don’t tackle both hemodynamics and oxygenation, so they’re not sufficient as standalone treatments for right-sided failure.
