I don't feel like going through my stack of magazines to try to find the article (I'm almost positive that's where it came from either Discover or Scientific American.) So, I did a web search. Found a bunch of links.
Found a few others that all seemed to talk about the same thing. Using bone marrow stem cells rather than embryonic stem cells.

None of these are the ones that I saw before though. The one I saw showed a before and after picture of the heart. Showed how much healthier the muscle was after the procedure. I really don't think it said where the stem cells came from. I'd be willing to bet that it's these same stem cells though.
In the latest advance, Victor Dzau and his colleagues at the Brigham and Women's Hospital in Boston inserted a cell-survival gene called Akt1 into a type of bone-marrow stem cell. They injected the cells into rats whose hearts had been starved of oxygen as happens when blocked arteries cause a heart attack.
More than 60% of the modified cells survived for 48 hours. What's more, they halted the heart's subsequent decline towards failure. "It's pretty amazing," says Stanton Gerson, who studies blood stem cells at Case Western Reserve University in Cleveland, Ohio.
