EXPERIMENT INFORMATION

Vascular Echocardiography (Vessel_Imaging)
Principal Investigator
Research Area:
Cardiovascular physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
Vascular Echography (Vessel Imaging) evaluates the changes in central and peripheral blood vessel wall properties (thickness and compliance) and cross sectional areas of long-duration International Space Station crewmembers during and after long-term exposure to microgravity.

ESA's Vessel Imaging experiment evaluates the changes in central and peripheral blood vessel wall properties and cross sectional areas of long-duration ISS crewmembers during and after long-term exposure to weightlessness. A Lower Body Negative Pressure programme runs in parallel to Vessel Imaging. Flow velocity changes in the aorta and the middle cerebral and femoral arteries are used to quantify the cardiovascular response to fluid shifts. Vessel Imaging aims to optimise the countermeasures used routinely during long-duration space missions. The aim of the Integrated Cardiovascular experiment is to determine the degree, development and clinical significance of cardiac atrophy and identify its mechanisms.
