In pigs, a new injectable hydrogel can repair damage from heart attacks, help the heart grow new tissue and blood vessels, and get the heart moving closer to how a healthy heart should.
University of California, San Diego bioengineers have demonstrated this in a study.
The results of the study were published Feb. 20 in Science Translational Medicine
and clear the way for clinical trials to begin this year in Europe. The gel is injected through a catheter without requiring surgery or general anesthesia -- a less invasive procedure for patients.
