It is due to allowing the heart to largely rest those affected cells.
Correction: the device is not a transplant.
It is instead of a transplant. Sorry about that.
“Unexpected” is what we call phenomenon that occur outside of the orthodoxy of scientism
That's the theory for why people's native heart function can improve after having been on an LVAD. This improvement is not uncommon. The broad theory postulates that metabolic parameters and gene expression patterns can revert to normal when the hemodynamic overload on the myocardium is decreased with an assist device.
Regarding the 'regeneration' issue, adult cardiomyocytes can definitely have nucleic acid synthesis and even nuclear division, but cytokinesis (actual cell division) is rare or non-existent after cardiomyocytes mature.
I will read the paper and keep an open mind.
“ Said Hesham Sadek, MD, Ph.D., “When a heart muscle is injured, it doesn’t grow back. We have nothing to reverse heart muscle loss.”
Sadek led a collaboration between international experts to investigate whether heart muscles can regenerate.
The investigators found that patients with artificial hearts regenerated muscle cells at more than six times the rate of healthy hearts.”

This seems to be contradictory. On the one hand, this guy says that heart muscle can’t grow back. On the other hand, with an artificial heart, the muscle tissue grows back at six times the rate of unassisted heart tissue. Thus, unassisted heart tissue DOES grow back. Well which is it?
As for me, not being a doctor or a scientist, it seems to me that stem cells naturally present in our bodies that help to perform rebuilding of various tissues would also do the same in the heart. The rebuilding is not necessarily perfect or complete, but it would seem that some improvement would be possible overtime. Of course, through diet one can affect the number of stem cells that are circulating in your bloodstream. Having had a heart attack this past summer, I would welcome any comments on this matter.
