Summary

Story summary

Massachusetts Institute of Technology (MIT) engineers developed TIMED, a patch to aid heart-attack recovery.
Applied during bypass surgery, TIMED releases three drugs at intervals to promote healing.
In rat studies, TIMED reduced damaged heart tissue by 50% and improved survival by 33% versus untreated groups.
The hydrogel withstands heart motion and dissolves over a year.
Researchers plan larger-animal tests and explore stent applications; findings are published in Cell Biomaterials.
