lifts, quietly—. An image enters in,
rushes down through the tensed, arrested muscles,
plunges into the heart and is gone.

And, with a mighty heave, I helped to beat the other side!

SEATTLE (KCPQ) — Medical researchers at the University of Washington say they believe they've found a way to regrow damaged heart muscle with stem cells.
Stem cells heal heart attack scars, regrow healthy muscle.
In a small study involving 25 volunteers, stem cell recipients had their heart attack scars reduced most dramatically - on average, 50 percent - and damaged muscle replaced by new healthy heart tissue.
Scientists say they have successfully converted the scar tissue that forms after a heart attack into heart muscle.
