The potential success of this research could hold a lot of promise for the millions of Americans who suffer from heart disease each and every year, which is the leading cause of death in the United States.

In a ground-breaking study that may change how heart attacks are treated, Dr. Eduardo Marban and his team used stem cells to re-grow damaged heart muscle. In the 17 patients who received the therapy, Marban measured an average 50 percent reduction in the size of the scar tissue
“One of the holy grails in medicine has been the use of medicine to achieve regeneration,” Marban said. “Patients that were treated not only experienced shrinkage of their scars, but also new growth of their heart muscle, which is very exciting.”
