Abstract : Clinical features of 27 cases of Chronic Mountain Sickness(CMS) from the Himalayas are reported. They are compared with 75 native high landers(NH). All CMS patients were immigrants to high altitude. Mean duration of stay at high altitude was seven years. Mean values for haematocrit and haemoglobin were 80% and 23G% respectively for the CMS group and 40% and 17.9G% respectively for the native highlanders group. Mean QRS axis in the firmer was +118 and in the latter +76. Incidence and quantum of protienuria were significantly higher in the CMS group. Cardiac catheterisation studies done in eight CMS cases showed elevated Pulmonary Artery(PA) pressures even after a mean of 14.2 days at sea level. The disease which has four diagnostic elements hypoxemia and polycythemia, pulmonary hypertension, right ventricular enlargement and nephropathy with dense proteinuria is a variant of 'Monge's Disease' and a name classification which may help in diagnosis before cor pulmonale sets in indicate that yogic deep breathing exercise, low dose aspirin and diamox may be beneficial in the prevention and therapy of CMS Phobrang Type at high altitude.
