- Some patients receive a mechanical heart pump.
- The pump is called an LVAD device.
- An LVAD helps the heart rest and recover.
- Doctors took small tissue samples from the heart.
- Researchers tested these samples in the lab.
- They found a protein called PERM1 in samples.
- PERM1 returned only in hearts that recovered.
- Hearts that did not recover kept low PERM1.
- This finding may help future treatments for hearts.
