EXPERIMENT INFORMATION

Pre- and Postflight Cardiac Assessment (DSO 466)
Principal Investigator
Research Area:
Cardiovascular physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
Space flight causes adaptive changes in cardiovascular function, and many astronauts have suffered postflight orthostatic tachycardia. However, previously available data about these changes have been inadequate and inconsistent. The objective of this study was to collect normative data about the effects of space flight on the volume, mass and function of the heart, and about the orthostatic response of the cardiovascular system.
