What this trial studies

This clinical trial evaluates the effects of a nutritional immune modulating intervention using Ensure Surgery Immunonutrition shake on heart failure patients awaiting left ventricular assist device (LVAD) implantation. The study aims to determine if pre-surgical supplementation can improve gut microbiome composition, reduce systemic inflammation, and decrease post-surgical complications such as infections and length of ICU stay. Participants will be assessed for malnutrition and provided with the nutritional shake in the days leading up to their surgery.

Who should consider this trial

Good fit: Ideal candidates are hospitalized adults over 18 years old who are scheduled for LVAD therapy.

Not a fit: Patients who are intubated, have congenital heart disease, or cannot tolerate oral nutrition may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could improve recovery outcomes and reduce complications for heart failure patients undergoing LVAD implantation.

How similar studies have performed: Other studies have shown promising results with nutritional interventions in similar patient populations, suggesting potential for success in this approach.
