摘　　要：长期太空飞行面临的失重环境会导致人体心血管系统产生一系列适应性改变,从而影响航天员的健康,并在重返地球重力环境时危及航天员的安全。太空失重可导致心输出量增加,中心静脉压、心率、血压、血管外周阻力下降,并抑制心血管调节功能,从而对人体心血管的生理健康构成潜在威胁。本文主要对太空失重的心血管效应进行系统综述,以期为后续航天飞行过程中心血管功能的防护研究提供参考和借鉴。The weightlessness environment faced by long-term space flight will lead to a series of adaptive changes in the human cardiovascular system,which will affect the health of astronauts and endanger the safety of astronauts when returning to the earth's gravity environment.Weightlessness in space can increase cardiac output,reduce central venous pressure,heart rate,blood pressure and peripheral vascular resistance,and inhibit cardiovascular regulation,thus posing a potential threat to the physiological health of human cardiovascular system.In this paper,the cardiovascular effects of space weightlessness are systematically reviewed in order to provide reference for the protection of cardiovascular function during subsequent space flight.
