Arterial structure and function in the years after long-duration spaceflight

Year: 2025

Type: article

Abstract: Previous investigations focused on in- and immediate postflight cardiovascular health indices. Here we report that in the 5 years after long-duration spaceflight in low Earth orbit, there was no evidence of increased carotid artery intima-media thickness or reduced brachial artery endothelium-dependent vasodilation in 13 middle-aged male and female astronauts. Additionally, biomarkers of oxidative stress and inflammation are dynamic in the days after landing and may not reflect the long-term health consequences of spaceflight.
