Injecting pond scum into the heart could be a ‘game changing’ treatment for cardiac arrest

Researchers are testing using pond bacteria to treat heart attack victims.

These bacteria use light to produce oxygen via photosynthesis, and when researchers injected it in the hearts of rats with heart disease, it increased oxygen flow and improved their heart function.

While still at an early stage of research, the bacterial therapy could potentially be a game-changer in treating heart disease in humans.
