MIT engineers have created a flexible drug delivery patch that could transform recovery for heart attack survivors, offering hope to millions who face permanent heart damage. The innovative patch can be placed directly on the heart during surgery and releases three different medications on a carefully programmed schedule over two weeks. In studies with rats, the results were nothing short of remarkable, the treatment reduced damaged heart tissue by 50 percent and significantly improved overall cardiac function.
The patch works like a precisely timed healing system, releasing drugs exactly when the heart needs them most during its natural repair process. First it delivers a growth factor to prevent cell death, then promotes new blood vessel formation, and finally blocks scar tissue from developing. Made from biodegradable materials similar to a contact lens, the thin flexible patch gradually dissolves in the body over time. If approved for human use, this breakthrough could help heart attack patients recover far more heart function than is currently possible with standard treatments.
