Apollo Lunar Astronauts Show Higher Cardiovascular Disease Mortality: Possible Deep Space Radiation Effects on the Vascular Endothelium
Radiation Biology & DNA Damage
Abstractive Summary
Study examining apollo lunar astronauts show higher cardiovascular disease mortality:. Spaceflight causes significant cardiovascular deconditioning, including cardiac atrophy, reduced blood volume, and vascular changes. Most crew members develop orthostatic intolerance post-flight, with impaired cerebral blood flow regulation. Arterial stiffness increases, presenting challenges for re-adaptation to gravity.
Extractive Summary
Study examining apollo lunar astronauts show higher cardiovascular disease mortality:. Cardiovascular deconditioning was observed with reduced cardiac mass and altered vascular function. Blood volume decreased by 10-15% within first weeks. Orthostatic intolerance developed in 70% of crew post-flight. Carotid artery stiffness increased during flight. Cardiac atrophy affected left ventricular mass. Cerebral blood flow regulation was impaired upon return to gravity.
