Summary: Deep space exploration is a new environment that humans could be exposed to in the future, where health risks associated with long-term exposure to microgravity and space radiation needs to be assessed. The cardiovascular system is known to be sensitive to radiation, therefore, cardiovascular disease needs to be considered when examining the impact of deep space exploration. Furthermore, the risk of cardiovascular disease is also enhanced through factors independent of radiation, including that of the reduced gravitational loading that occurs in microgravity. Cardiovascular disease is one of the most devastating health problems in the modern world, with heart failure and hypertension impacting a rising percentage of the aging population. A greater understanding of the cardiovascular system in these extreme environments, may unlock new insights into the understanding of cardiovascular diseases.
