Doctors Discover the Human Heart Can Regrow Its Own Muscle After a Heart Attack

A world-first study by researchers at the University of Sydney, the Baird Institute, and Royal Prince Alfred Hospital has found that the human heart can regrow muscle cells after a heart attack, a repair ability that scientists had only ever seen in mice. The findings, published in the journal Circulation Research in 2026, overturn the long-held belief that heart muscle damaged by a heart attack is permanently lost. Researchers say the natural repair response is currently too weak to replace all the lost muscle, but they hope that understanding it can lead to new treatments for heart failure.
