title: [Analysis on the correlation between SF-36 and QOL-35 in patients and coronary artery disease].
abstract: OBJECTIVE
  To analyze the correlation between SF-36 and QOL-35 and the consistency of the two kinds of life-quality questionnaires when evaluating the quality of life in patients with coronary heart disease.
  
  
  METHODS
  781 in-hospital-patients, who underwent coronary angiography from June 2008 to April 2009, were included in this study. Quality of life was measured by the Chinese versions of SF-36 and QOL-35. Demographic and clinical information were collected. Correlation Analysis was done between SF-36 and QOL-35 in the patients with coronary artery disease.
  
  
  RESULTS
  The total score of SF-36 was 62.63 ± 12.47 and the QOL-35 total score was 62.70 ± 9.69. Data from the simple correlation analysis showed that SF-36 and QOL-35 total scores (r = 0.725, P < 0.01), SF-36 physical functioning and QOL-35 independent living capacity (r = 0.933, P < 0.01), SF-36 mental health and QOL-35 mental health(r = 0.132, P < 0.01), SF-36 social function and QOL-35 social function score (r = 0.215, P < 0.01) were all relevant. Canonical correlation analysis showed that there was significant correlation between SF-36 and QOL-35 (r = 0.946, P < 0.01).
  
  
  CONCLUSIONS
  SF-36 and QOL-35 were consistent in the evaluation on the quality of life, at the overall level.
