Following a heart attack, patients’ damaged heart tissue has trouble healing, which weakens pumping and the heart’s electrical signal. Research conducted by Trinity College Dublin has worked to address the problem through developing a patch. It is hoped that the patch will eventually help the heart create healthy cells to replace the damaged cells. Currently, the patch mimics the direction-dependent mechanical movements so that the heart can continue to operate. The patches are made of a polyester-based thermoplastic polymer that has been modified to better withstand the constant beating of the heart.
