title: [The preliminary results of prevention and treatment in the population of patients with COPD and cor pulmonale].
abstract: This paper tends to evaluate the effects of comprehensive prevention and treatment in COPD and cor pulmonale in the communities. A Randomized cohort with stratified design was undertaken in the rural areas with hundred thousand population in Beijing municipality, Lianning and Hubei Provinces, from spring 1992 to spring 1995.
  
  
  RESULTS
  (1) the rates to all stratified populations under management were 85.6% among those with high risk, 87.8% among COPD and 83.6% among cor pulmonale, respectively. (2) The levels of KAB were raised more significantly in most intervention group than in control group which up +9.6% to +33.6% and -5.8% to +32.6%, respectively. (3) Comparisons between the two groups revealed: 1. Number of cigarette smokers who smoked more than before increased (20.1% vs 17.8%) but with no statistical significance. 2. The rate of smoking cessation went higher (15.5% vs. 11.3%, P < 0.01). 3. New high risk subjects were reduced (2.8% vs 3.9%, P < 0.01). 4. Number of new cor pulmonale patients decreased (19.9% vs 22.6%, P > 0.05) and mortality rate lowered (4.34% vs 4.78%, P > 0.05).
  
  
  CONCLUSIONS
  preliminary results indicates that the active intervention is effective in reducing COPD and cor pulmonale among population at high risk in communities. However, it is necessary to point out that COPD and cor pulmonale are both having chronic nature which calls for patient and continuous efforts.
