Question

Ron asked:

What is is success rate for stem cell therapy after heart attacks ?

Answer

There is evidence in animals that you can get improved cardiac output afterwards. The stem cells might give rise to new heart muscle cells, or promote the growth of new blood vessels which improve blood supply to the heart muscle, helping it to work more efficiently.
