Chart STM0213 (image) University of California - San Diego Caption UC San Diego bioengineers demonstrated in a study in pigs that a new injectable hydrogel gets hearts moving more like they should -- as measured by the Global Wall Motion Index (GWMI) -- in hearts following heart attack. After a heart attack, the score was elevated; however, for pigs that were treated with the hydrogel, this index score dropped back closer to normal.
