Which statement is true about LVAD indications as described in the material?

• A. EF less than 25% is an indication
• B. EF greater than 50% is an indication
• C. No LV dysfunction is an indication
• D. Only diabetes is an indication

Answer: (A)

The important idea is that LVADs are used for advanced left ventricular failure with reduced ejection fraction, not for preserved function or based on diabetes alone. When the left ventricle is severely failed despite optimal medical therapy, an LVAD can unload the ventricle and improve perfusion, serving as a bridge to transplant or as long-term support. This scenario is typically characterized by a very low ejection fraction, often around or below 25%, which signals substantial systolic dysfunction.

If the ejection fraction is greater than 50%, the heart is pumping well enough on its own, so an LVAD isn’t indicated. LV dysfunction is precisely what the device treats, so no LV dysfunction would mean there’s no LVAD indication. Diabetes by itself does not qualify someone for an LVAD; comorbidity considerations and overall prognosis matter, but diabetes alone isn’t an indication.
