A team of researchers affiliated with several institutions in Germany and one in Canada has found that it is possible to reprogram heart muscle to repair damaged tissue. In their paper published in the journal Science, the group describes their approach to repairing damaged hearts in mice and how well it worked when tested.

There are two main kinds of heart attack. The first occurs when something prevents the heart from beating. The second occurs when blood flow is restricted to parts of the heart, preventing the muscle in that area from beating. The first kind is generally fatal unless the heart can be restarted very quickly. The second is generally less serious, but can leave permanent, debilitating scarring. In this new effort, the researchers have found a way to prevent such scarring—at least in mice.
