Why the study?
Does acute exposure to high altitude alter systemic blood pressure, arterial stiffness, and vascular tone?
Population
17 subjects (including 3 with mild hypertension)
Comparison
Acute exposure to high altitude over 11 days vs Baseline measurements prior to ascent
Design
Cohort
Follow-up
11 days

Acute altitude exposure raises BP without sustained stiffness changes; leaves open AMS relevance and needs prospective validation.
Does acute exposure to high altitude alter systemic blood pressure, arterial stiffness, and vascular tone?
Acute high altitude exposure significantly increases systemic blood pressure without sustained changes in arterial stiffness or tone, and these vascular changes do not predict acute mountain sickness.
Rhodes et al. (2011) studied this question.
