Forty four cases (34 males and 10 females) of established COPD of 60 years of age and above, admitted in one of the medical units of Medical College Hospital, Shimla during 1981-85 (followed upto June 1987) were studied. All the subjects had advanced airway obstruction and 68.2% of them had cardiac failure at the time of entry into the study. Five year survival was 5.2% and the common causes of death were respiratory and cardiac failure. Smoking was a common factor in males but six out of 10 females were non-smokers. The study showed high mortality and poor five year survival in the group studied. Ambient hypoxia of the hilly region could have contributed to the poor prognosis of COPD patients in Shimla.
