High Altitude Pulmonary Edema in a Mining Worker With an Abnormal Rise in Pulmonary Artery Pressure in Response to Acute Hypoxia Without Prior History of High Altitude Pulmonary Edema.

High altitude pulmonary edema (HAPE) is a potentially life-threatening form of noncardiogenic pulmonary edema that may develop in otherwise healthy individuals upon ascent to high altitude. A constitutional susceptibility has been noted in some individuals, whereas others appear not to be susceptible at all. In our report, we present a case of HAPE triggered by concurrent respiratory tract infection and strenuous exercise in a mining worker with an abnormal rise in pulmonary artery pressure in response to acute hypoxia, without a prior history of HAPE during almost a year of commuting between high altitude and lowland areas.
