Robert Boyce enjoys fishing again after three heart attacks forced him to give it up. Then he joined a study at the University Of Miami Miller School Of Medicine, and in May 2009 had his own stem cells injected into his damaged heart.
"Since the procedure, physically I feel better. I breathe a lot better. I do have a little more stamina than I had," said Robert Boyce a patient.
He is one of eight heart failure patients in a UM trial published in Circulation Research: Journal of the American Heart Association.
Among the findings: all eight patients had a positive response, heart size decreased 15 to 20 percent, scar tissue decreased 18 percent.
