Scientists have invented a new method of recovering from a heart attack

Ученые придумали новый способ восстановления от инфаркта

In the heart of the offer to implant bacteria.

Scientists at Stanford University published a report in which describe a new method of recovery of the heart after a heart attack – with implantation of the bacteria that produce oxygen in photosynthesis.

The report, published in the journal Science Advances says that while the test passed successfully on lab rats, but scientists hope that in the future the method will be applied to people.

Cause of heart attack is cessation of blood supply to the heart muscle. Due to the fact that blood vessels are clogged, the heart is not receiving needed oxygen along with blood flow.

But if it is a critical moment, “why not take the plant itself or the mechanism of photosynthesis and apply it directly to the heart?”, quoted Scientist one of the study’s authors, Stanford Professor Joseph Wu.

Scientists have suggested that if implanted in a heart capable of photosynthesis in the unicellular cyanobacterium Synechococcus elongatus, it will help to remove carbon dioxide and provide muscle heart cells with oxygen and glucose required for metabolism in the absence of blood supply.

Method decided to try on a living organism. Rats mimicked a heart attack, has put in their heart muscle cyanobacteria, and then sent to the heart of the rays of light. After 10 minutes, oxygen levels in the hearts of rodents was much higher than in the control group and those rats who introduced the cyanobacteria in the heart, but not subjected to light radiation. After 45 minutes in the first group also improved the contractility of the ventricles.

This method is proven as non-toxic and showed that does not cause reactions in the immune system. In addition to its primary purpose, the introduction of Synechococcus elongatus can help to support the organs stored for transplantation.

However, scientists are urged not to jump to conclusions – it is not known how the bacteria will be perceived by the human heart. A big disadvantage of this method of treatment is an open heart operation, that is, the open chest, which is accompanied by greater risks.

Scientists are working to make the new method more secure, namely, trying to figure out how to enter the cyanobacteria are not directly in the heart and through the veins, as well as “to hold” to the heart of the rays of light through the skin and bones, to avoid dissection of the chest, Wu told the Verge.

Note, the use of sugar in large quantities increases the risk of cardiovascular disease.
