Moscow. July 29. INTERFAX.RU – American scientists have concluded that spaceflight beyond Earth orbit dramatically increase the likelihood of death from cardiovascular disease (CVD). This is most likely due to the influence of cosmic radiation, the website N + 1. The results were published in Scientific Reports journal

Employees of the University of Florida and colleagues from other research centers analyzed the causes of death of the astronauts, members of the three groups. never flew in space, who were on a low Earth orbit and the members of lunar mission ” Apollo “- only today people go beyond the Earth’s magnetosphere (there have been 24 so far, eight have died)

it was found that the death rate from cardiovascular disease among astronauts.” Apollo “(43 percent) about four times higher than their counterparts, to train in the world (nine percent) and fly at low Earth orbit (11 percent).

to determine the possible cause of such patterns, the researchers exposed lab mice to radiation similar to space , simulated weightlessness, and both factors at the same time.

it turned out that weightlessness makes the unexpressed negative impact on the cardiovascular system, but for half a year (equivalent to 20 years of life) its effects are offset. In mice exposed to radiation with simulated weightlessness or not, over the same period were observed pronounced dysfunction of the inner lining (endothelium) of arteries. Such violations are at the heart of atherosclerosis and caused them to diseases such as coronary heart disease (including heart attack), ischemic stroke and others.

Thus, long space missions have a negative impact on the cardiovascular system, it must be borne in mind when planning future missions beyond earth’s magnetosphere.
