I don't think that is true. My husband had two heart attacks twenty years apart with one stent and one bypass. His heart today has a normal ejection fraction for his age. His valves are all normal. He does have minor thickening. His heart was not good at all 2 years ago. Maybe the ivermectin for his two bouts of COVID cured him.
He was also told 20 years ago that he was in heart failure. He wasn't. It was a reaction to a diabetic drug the hospital started him on.
Neural pathways are rerouted. So they can learn to do things again. But the nerves that carried the signals are gone. What was damaged, will not regeneratet. The person may re-learn; but that is the amazing part of a neural design
A few organs in our body do not heal. Heart, brain and spine are examples

This isn’t true, the brain can heal. Brain lesions can heal, I’ve known people whose MRIs proved it.
