Cardiac hemodynamics at rest and during LBNP after 4 days and 6 weeks in HDT.
The first objective was to assess the left ventricle function at rest, at the end of a short term (4 days) HDT, and at the end of a long term (6 weeks) HDT. The second objective was to check if these short and long HDT induced any abnormal cardiac hemodynamic response to LBNP (lower body negative pressure) test that could be related to orthostatic intolerance.
