Pilot Study of Preoperative Nicotinamide Riboside (Vitamin B3) Supplementation in Patients Undergoing Elective Left Ventricular Assist Device (LVAD) Implantation
In Brief
A Early Phase 1 clinical trial evaluating Nicotinamide riboside for Heart Failure，Congestive and 2 related conditions. Completed, enrolled 5 participants across 1 site.
Detailed Summary
While preliminary data show that oral nicotinamide riboside (NR) supplementation increases myocardial levels of oxidized nicotine-adenine dinucleotide (NAD+) levels in mice, there has been no direct evidence that suggests oral NR increases NAD+ levels or improves mitochondrial function in human hearts. This Pilot Study is designed to obtain feasibility data for a planned, larger study testing the hypothesis that oral NR supplementation will increase myocardial NAD+ levels and improve cardiomyocyte mitochondrial function in participants with advanced heart failure planned for elective left ventricular assist device (LVAD) implantation. To demonstrate safety and feasibility of NR in this patient population, the investigators propose to enroll 5 participants planned for LVAD implantation in a Pilot Study of NR in which participants will receive NR, up-titrated over 3 days to a final NR dose of 1000mg twice daily. Blood and myocardial tissue analyses collected previously from age- and gender-matched LVAD recipients will serve as controls.
