Heart Tissue Shows Signs of Aging
Space Travel May Not Be Healthy for Heart Muscle
WEDNESDAY, Sept. 25, 2024 (HealthDay News) -- Long-term space travel to Mars could be bad for astronauts’ hearts, a new zero-gravity study shows. After a month at the International Space Station, a set of 48 bioengineered human heart tissue samples beat about half as strong as similar tissues that remained on Earth.
The human heart shows signs of ageing after just a month in space
Over the course of just one month in space, engineered human heart tissue got weaker, its ‘beating’ patterns became irregular and it underwent molecular and genetic changes that mimicked the effect of ageing 1. The findings are published in the Proceedings of the National Academy of Sciences today.
