A new patch has been developed to help the heart heal after a heart attack. This patch uses a microneedle system to deliver a molecule called IL-4 directly to damaged areas of the heart. IL-4 helps heal tissue by supporting immune cells.
After a heart attack, heart muscle becomes weak and forms scar tissue. This patch aims to reduce this scar tissue and improve healing by changing how immune cells respond. It focuses on the heart, which is important because other treatments have affected the whole body.
