When you suffer a heart attack, a part of your heart dies. Nerve cells in the heart’s wall and a special class of cells that spontaneously expand and contract – keeping the heart beating in perfect synchronicity – are lost forever. Surgeons can’t repair the affected area. It’s as if when confronted with a road riddled with potholes, you abandon what’s there and build a new road instead. Needless to say, this is a grossly inefficient way to treat arguably the single most important organ in the human body. The best approach would be to figure out how to resuscitate the deadened area, and in this quest, a group of researchers at Brown University and in India may have an answer.
