越来越多的太空机构和私人公司计划在未来的几十年里载人飞行进入太空，了解辐射的持续健康效应将变得越来越重要，对人类太空探索领域也是至关重要的。

Michael D. Delp博士就航天对动物的心血管系统影响研究超过2年，他发现，在深空任务中遇到的辐射和剂量让动物出现血管内皮功能障碍，让其更易患动脉粥样硬化。

那么航天对航空员的心血管有啥影响？

1968年到1972年前往月球的阿波罗计划团队成员共有24人。当佛罗里达州立大学人文科学学院院长Delp教授决定研究航天人员死因时，有7名阿波罗月球宇航员已经死亡，其中3人被确定为心血管疾病死亡。

研究团队发现，阿波罗宇航员与35名非宇航员和相同数量近地轨道（LEO）任务的宇航员比较，心血管疾病死亡率高出4-5倍！

没有飞入太空深处的2组人员间的心血管疾病死亡率没有显着差异。

这表明，超出了地球磁气圈保护的宇航员，其心血管疾病的发病率增加！

Delp教授称：“关于深空辐射对心血管系统的长期影响，尚不能得出明确结论，还需要更多的研究。”

安大略滑铁卢大学的血管老化与脑健康研究主席Richard L. Hughson博士说：“尽管样本量小，但仍提出了一项十分有趣的假设，关于深空中可能发生的事情。”
