Human Heart Regrows Muscle Cells After Heart Attack

Scientists in Australia have made a big discovery.

They found that the human heart can grow new muscle cells after a heart attack.

Before this, people thought that heart cells die and the heart gets permanently damaged.

But now, they know that new cells can grow, which is exciting.

This discovery could help doctors find new ways to treat heart failure in the future.

The researchers used heart tissue from patients who had bypass surgery to make this discovery.

Heart attacks can damage a lot of heart cells, so this new finding gives hope for better treatments.
