Injectable, biodegradable technology developed by UK team works as a scaffold to help new tissue grow
British researchers have developed a biodegradable gel to repair damage caused by a heart attack in a breakthrough that could improve the health of millions of survivors worldwide.
Until now, when cells have been injected into the heart to reduce the risk of heart failure, only 1% have stayed in place and survived. But the gel can hold them in place as they graft on to the heart. Echocardiograms and electrocardiograms on mice confirmed the safety of the gel. To gain more knowledge, researchers will test the gel after mice have a heart attack to show they develop new muscle tissue.Prof James Leiper, an associate medical director at the BHF, said: “We’ve come so far in our ability to treat heart attacks and today more people than ever survive. However, this also means that more people are surviving with damaged hearts and are at risk of developing heart failure.
