Official Title: Study of the Effects of Iron Supplementation on High Altitude Pulmonary Hypertension.
Brief Summary: Body iron levels may be important in determining how the blood pressure in the lungs changes in response to low oxygen levels. At high altitude, where oxygen levels are low, some patients develop elevated lung blood pressure. The investigators hypothesize that, in high altitude residents with elevated lung blood pressure, iron supplementation will cause a reduction in lung blood pressure.
