title: The Polish MacNew heart disease heath-related quality of life questionnaire: a validation study.
abstract: BACKGROUND
  The MacNew health-related quality of life questionnaire was designed to assess feelings about how heart disease affects their daily physical, emotional and social functioning in patients with 1 of the 3 major coronary artery diagnoses, stable coronary artery disease (CAD) with angina, ST-elevation myocardial infarction (STEMI), and ischemic heart failure (HF). The aim of this study was to determine the reliability and validity of the Polish version of the MacNew in patients with CAD.
  
  
  METHODS
  Patients with CAD completed a self-report sociodemographic and clinical ques-tionnaire: the MacNew, the Short-Form 36 Health Survey, and HADS at baseline; 10% of the patients completed each questionnaire 2 weeks later.
  
  
  RESULTS
  We studied patients with stable CAD with angina (n = 115), with STEMI (n = 112), and with ischemic HF (n = 105). Internal consistency reliability was demonstrated with Cronbach's a from 0.86 to 0.95 for the MacNew global scale and subscales. The original 3-factor structure was confirmed for the Polish version of the MacNew explaining 53.5% of the variance. Convergent validity of similar MacNew and SF-36 subscales was confirmed in the total group and in each diagnosis. Discriminant validity with the SF-36 health transition was fully confirmed in the total group and in patients with HF and partially confirmed in patients with stable CAD with angina or myocardial infarction.
  
  
  CONCLUSIONS
  The Polish MacNew health-related quality of life questionnaire can be recommended in patients with stable CAD with angina, myocardial infarction and HF.
