New Hope for Fixing Broken Hearts – Research Shows Heart Damage Can Be Reversed

It has long been thought that damage to the heart is irreversible, but new research is challenging that assumption.
Investigators from Children’s Hospital Boston were able to reverse heart damage in mice by stimulating the growth of new heart muscle cells.

They did this by injecting the mice with the growth factor neuregulin1, which is a key player in heart cell growth.
Until recently, most experts believed that the heart muscle could not repair itself, in part because the cells responsible for its development stop proliferating after birth.

But recent studies have shown that these heart muscle cells, known as cardiomyocytes, do have
