A simple technique temporarily restricting the arm's blood supply before heart bypass surgery significantly improves the chances of a full recovery—and could one day be used to prevent cardiac arrest, reports the Guardian. The technique uses cycles of arm compressions with cuffs to remotely restrict  blood flow to the heart.

Scientists aren't sure exactly how the technique works. But animal studies suggest that it may be effective in preventing heart damage and even cardiac arrest if used during heart attacks. "This has the potential to be pretty important," said a heart expert. "There is clearly a way to remotely condition the heart to protect against damage." (More heart disease stories.)
