- Researchers made a new injection for the heart.
- It may help after a heart attack.
- Doctors give the injection into skeletal muscle.
- The shot tells muscle cells to make a hormone.
- The hormone is called ANP and it helps.
- ANP reduces stress on the heart.
- One dose made the hormone for several weeks.
- The hormone travels in blood to the heart.
- The treatment may reduce scarring and help pumping.
- Scientists will study safety before human tests.
