title: Anxiety and health-related quality of life in patients awaiting elective coronary angiography.
abstract: OBJECTIVE
  The purpose of this study was to document the impact of waiting for first-time elective coronary angiography (CA) on patients' anxiety and health-related quality of life (HRQL).
  
  
  METHODS
  A prospective, observational inception cohort pretest and posttest design was used.
  
  
  METHODS
  The study was conducted in a tertiary community cardiac center in Toronto, Canada.
  
  
  METHODS
  Disease-specific HRQL was measured using the Seattle Angina Questionnaire at baseline (Time 1 [T1]) and 1 week before CA (Time 2 [T2]). The association between time on the waiting list and subjects' perceived anxiety was analyzed.
  
  
  RESULTS
  Paired-sample t tests comparing mean anxiety levels at T1 and T2 indicated a statistically significant increase in anxiety levels at T2 that did not seem to be related to the waiting time for CA (P =.000). Comparison of mean Seattle Angina Questionnaire scores at T1 and T2 indicated a trend toward deterioration in HRQL over time.
  
  
  CONCLUSIONS
  Waiting for elective CA may have a negative impact on patients' psychologic status and HRQL. Nursing and clinical interventions to reduce anxiety and improve HRQL are indicated for this population.
