Key result
NAD+ supplementation shows therapeutic promise for improving myocardial energy metabolism in heart failure.
Why the study?
Decreased NAD+ levels in myocardial cells lead to inadequate ATP production and increased susceptibility to heart failure, motivating exploration of NAD+ targeting therapies.
Does NAD+ supplementation improve myocardial activity and heart function in patients with heart failure?
Does NAD+ supplementation improve myocardial activity and heart function in patients with heart failure?
Targeting NAD+ as a central component of energy metabolism represents a promising therapeutic strategy to address energy deficiency and improve heart function in heart failure.
NAD+ repletion may merit trials in HFpEF; leaves open clinical efficacy pending randomized confirmation.
Heart failure is a condition where reduced levels of adenosine triphosphate (ATP) affect energy supply in myocardial cells.Nicotinamide adenine dinucleotide (NAD + ) plays a crucial role as a coenzyme for electron transfer in energy metabolism.Decreased NAD + levels in myocardial cells lead to inadequate ATP production and increased susceptibility to heart failure.Researchers are exploring ways to increase NAD + levels to alleviate heart failure.Targets such as sirtuin2 (sirt2), sirtuin3 (sirt3), Poly (ADP-ribose) polymerase (PARP), and diastolic regulatory proteins are being investigated.NAD + supplementation has shown promise, even in heart failure with preserved ejection fraction (HFpEF).By focusing on NAD + as a central component of energy metabolism, it is possible to improve myocardial activity, heart function, and address energy deficiency in heart failure.

Wu et al. (2023) conducted a review in Heart Failure. NAD+ supplementation (e.g., NMN, NR) was evaluated. NAD+ supplementation shows promise as a therapeutic strategy to improve myocardial energy metabolism and alleviate heart failure, including heart failure with preserved ejection fraction.
