Reversal of Pulmonary Hypertension in a Patient with Chronic Mountain Sickness after Relocation to Low Altitude

High Altitude Mountain Sickness

Its probable first account has been given by Plutarch in his comments on Alexander’s invasion of India: “Many then were the dangers— but the greatest harm came from severity of weathers”. Similarly, a Chinese record mentions of “Lesser Headache Mountains” and the “Greater Headache Mountains” where men’s bodies become feverish, they lose color and are attacked with headache, dizziness and vomiti...

Chronic Mountain Sickness (Cms) Misdiagnosed As High Altitude Cerebral Edema (Hace) At Extreme Altitude (6400 M/21000 Ft)

Introduction: Chronic mountain sickness (CMS) represents a syndrome of secondary polycythemia along with thrombocytopenia, altered hemorheology, pulmonary and systemic hypertension, and congestive heart failure, occurring due to hypobaric hypoxia-anoxia-induced erythropoiesis reported in both native mountain residents and new climbers after prolonged stays at high and extreme a...

Acute mountain sickness without headache at low altitude

A 45-year-old tourist developed AMS three hours after starting to ski in a glacier skiing-region in Austria. His history was noteworthy for chronic stress, coffee-overuse, chronic sleep-deprivation, and previous AMS, 14 years ago at ∼3000 m and six years ago at ∼5100 m. He occasionally trekked to altitudes of 1500–2500 m without problems. The night before suffering AMS he had slept for four hou...

Selected contribution: Ventilatory response to CO2 in high-altitude natives and patients with chronic mountain sickness.

The ventilatory responses to CO(2) of high-altitude (HA) natives and patients with chronic mountain sickness (CMS) were studied and compared with sea-level (SL) natives living at SL. A multifrequency binary sequence (MFBS) in end-tidal Pco(2) was employed to separate the fast (peripheral) and slow (central) components of the chemoreflex response. MFBS was imposed against a background of both eu...
