简介
Key points
  • Information describing alterations in vascular function during either acute or prolonged normobaric or hypobaric hypoxia is sparse and often confounded by pathology and methodological limitations.
  • We show that high altitude exposure in lowlanders is associated with impairments in both endothelial and smooth muscle function, and with increased central arterial stiffness; furthermore, in all of these respects, lowlanders’ vasculature becomes comparable to that of natives born and raised at altitude.
  • Changes in endothelial function occur very rapidly in normobaric hypoxia, and partly under the influence of sympathetic nerve activity.
  • Thus, a lifetime of high‐altitude exposure neither attenuates nor intensifies the impairments in vascular function observed with short‐term exposure in lowlanders; such impairment and altered structure likely translate into an elevated cardiovascular risk.
