According to an article by StatNews.com, researchers have discovered that photosynthetic bacteria injected into the heart during cardiac arrest may keep heart cells alive by providing oxygen. The murine study was published in Science Advances.
While blocking blood flow to rats’ hearts for 60 minutes, researchers injected their hearts with cyanobacteria and shone a spotlight on the organ to induce photosynthesis. Rats who received the treatment had less heart damage 24 hours later, and improved heart function four weeks later.
