flag MIT engineers created a biodegradable patch that delivers drugs in sequence to repair heart tissue after a heart attack, reducing damage by 50% in rats.

flag MIT engineers have developed a biodegradable, flexible patch that delivers drugs in a precise sequence to repair heart tissue after a heart attack. flag Implanted during surgery, it releases neuregulin-1 to prevent cell death, VEGF to grow blood vessels, and GW788388 to reduce scarring, matching the heart’s natural healing timeline. flag In rat studies, the patch cut damaged tissue by 50% and improved heart function. flag Made from safe, degradable materials, it is still in preclinical testing but could one day transform recovery for heart attack patients.
