Heart muscle cells can completely recover from heart palpitations, and NAD (nicotinamide adenine dinucleotide) supplementation can speed up this process. This has been shown by a study published in the journal. Nature Biomedical Engineering.
Tachycardia, or rapid heartbeat, if left untreated, can lead to cardiomyopathy, a reduced ability of the heart to pump blood. In a new study, scientists obtained heart cells from human stem cells. They were electrically stimulated to cause increased contraction. During the first five days of stimulation, the cells’ ability to contract continuously dropped to about 50% of normal. But after the researchers stopped the electrical stimulation, the cells fully recovered within five days. This fits with what doctors already know about tachycardia-induced cardiomyopathy: it is usually reversible.
Scientists later showed that artificially produced heart muscle tissue healed faster if it was supplemented with nicotinamide adenine dinucleotide, a molecule that helps cells obtain energy from food. Tissues that received the supplement regained 83% of their original function on the first day, while tissues that did not receive the supplement showed little recovery.
The authors believe that giving patients NAD as a ready-made supplement or intravenous injection may speed the patient’s recovery.
