Abstract: BACKGROUND: Increasing iron bioavailability attenuates hypoxic pulmonary vasoconstriction in both lowlanders and Sherpas at high altitude. In contrast, the pulmonary vasculature of Andeans with chronic mountain sickness (CMS) is resistant to iron administration. Although pulmonary vascular remodeling and hypertension are characteristic features of CMS, the effect of iron administration in healthy Andeans, to our knowledge, has not been investigated. If the interplay between iron status and pulmonary vascular tone in healthy Andeans remains inta...
