Official title

Pilot Study to Evaluate the Effect of Nicotinamide Riboside on Skeletal Muscle Function in Heart Failure Subjects

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Background: People are living longer and are more likely to survive a heart attack if they have one. Longer life expectancy is good but it also means more people get chronic heart failure over time. This is a condition in which the heart doesn't pump blood as well as it should. Treatment of chronic heart failure has not improved much in a few decades. Researchers want to see if giving a dietary supplement to people with heart failure can help their heart function. The supplement is nicotinamide riboside (NR). Objective: To study how NR affects skeletal muscle function in people with heart failure. Eligibility: Adults ages 18-70 with clinically stable systolic heart failure Design: Participants will be screened with a medical history and physical exam. They will answer demographic questions and review their current medical treatments. They will have blood and urine tests. They will have an echocardiogram. This uses sound waves to test heart function. Participants will have 8 study visits over 16 weeks. At these visits, they will have some of the following: Repeat of screening tests Skin sample taken Skeletal muscle exercise Nuclear magnetic resonance (NMR) spectroscopy. Muscles will be measured while participants do foot exercises. Cardiopulmonary exercise testing. Participants may ride a stationary bike or walk on a treadmill. A facemask will analyze their breath. Heart and blood pressure measurements will be taken. Participants will take the supplement in pill form each day for 12 weeks. Pill bottles will be checked at study visits. Participants should not significantly change their activity levels during the study.
