When a person suffers a heart attack, the time it takes to get treatment is crucial. That's because once heart muscle tissue is damaged, it can't be healed.

A researcher from St. Boniface Hospital, however, has found a gene that could bring damaged heart tissue back to life.

"The cells that make up the heart muscle itself - once they're damaged or injured they're not replaced by new ones," said Dr. Lorrie Kirshenbaum, a researcher at St. Boniface Hospital.

Researchers had little success locating a key gene.

"This gene we've been chasing for about 12 years," said Kirshenbaum.

But now they've found it.
