TI  - Psychometric properties of the portuguese version of the Kansas City 
      cardiomyopathy questionnaire in dilated cardiomyopathy with congestive heart 
      failure.
PG  - 353-72
AB  - Several studies have shown that patients with congestive heart failure (CHF) have 
      a compromised health-related quality of life (HRQL), and this, in recent years, 
      has become a primary endpoint when considering the impact of treatment of chronic 
      conditions such as CHF. OBJECTIVES: To evaluate the psychometric properties of 
      the Portuguese version of a new specific instrument to measure HRQL in patients 
      hospitalized for CHF: the Kansas City Cardiomyopathy Questionnaire (KCCQ). 
      METHODS: The KCCQ was applied to a sample of 193 consecutive patients 
      hospitalized for CHF. Of these, 105 repeated the assessment 3 months after 
      admission, with no events during this period. Mean age was 64.4 +/- 12.4 years 
      (21-88), and 72.5% were 72.5% male. CHF was of ischemic etiology in 4% of cases. 
      RESULTS: This version of the KCCQ was subjected to statistical validation, with 
      assessment of reliability and validity, similar to the American version. 
      Reliability was assessed by the internal consistency of the domains and summary 
      scores, which showed similar values of Cronbach alpha (0.50-0.94). Validity was 
      assessed by convergence, sensitivity to differences between groups and 
      sensitivity to changes in clinical condition. We evaluated the convergent 
      validity of all domains related to functionality, through the relationship 
      between them and a measure of functionality, the New York Heart Association 
      (NYHA) classification. Significant correlations were found (p < 0.01) for this 
      measure of functionality i patients with CHF. Analysis of variance between the 
      physical limitation domain, the summary scores and NYHA class was performed and 
      statistically significant differences were found (F = 23.4; F = 36.4; F = 37.4, p 
      = 0.0001) in the ability to discriminate severity of clinical condition. A second 
      evaluation was performed on 105 patients at the 3-month follow-up outpatient 
      appointment, and significant changes were observed in the mean scores of the 
      domains assessed between hospital admission and the clinic appointment 
      (differences from 14.9 to 30.6 on a scale of 0-100), indicating that the domains 
      assessed are sensitive to changes in clinical condition. The correlation between 
      dimensions of quality of life in the KCCQ is moderate, suggesting that the 
      dimensions are independent, supporting the multifactorial nature of HRQL and the 
      suitability of this measure for its evaluation. CONCLUSION: The KCCQ is a valid 
      instrument, sensitive to change and a specific measure of HRQL in a population 
      with dilated cardiomyopathy and CHF.
