AB  - OBJECTIVE: To examine sleep before and after coronary artery bypass grafting 
      (CABG) as well as measuring of quality of life (QoL), and to see if changes in 
      subjectively rated sleep can be shown objectively by polysomnographic recordings. 
      SAMPLE: A consecutive sample of 38 male patients, aged 45-68, underwent CABG, 
      Twenty-two patients were graded in New York Heart Association (NYHA) classes III 
      or IV, and 16 in class I-II before surgery. METHODS: 24-hour polysomnographic 
      recordings, using the Oxford Medilog 9000 recorder, were performed 2 days prior 
      to surgery, on the first 2 post-operative days and 1 month after surgery. The 
      Nottingham Health Profile instrument (NHP) was used to measure QoL before and 
      after surgery. RESULTS: Following surgery there was a profound decrease in sleep 
      at night, and an increase in daytime sleep. During the second post-operative 
      recording period nocturnal sleep duration was reduced to 253.6 +/- 94.1 minutes, 
      with suppressed stages 3 and 4 sleep and lack, or slight recovery, of REM sleep. 
      Even though there were evident changes in both the distribution and nature of 
      sleep at night, daytime sleep increased and the total duration of sleep during 
      the 24-hour period was not significantly changed. The total sleep time was 421.1 
      +/- 76.8 minutes before surgery, 483.2 +/- 201.2 in the first period, 433.2 
      +/-201.4 minutes in the second 24-hour period post-operatively and 443.2 +/- 44.0 
      minutes at the 1-month follow-up. The NHP instrument demonstrated that 6 months 
      after surgery the quality of life was significantly improved. 
      Polysomnographically measured slow wave sleep was compared with the sleep section 
      in the NHP instrument both before surgery and at 1 month post-operatively. 
      CONCLUSIONS: In the immediate period following CABG, there is a change in 
      distribution of sleep, with reduction in nocturnal sleep duration and an increase 
      in daytime sleep, which had almost returned to pre-operative values 1 month after 
      surgery. QoL scores were improved 6 months after surgery. This study demonstrates 
      the importance of careful assessment of sleep and sleep disturbances for more 
      individualized nursing care in order to promote sleep in the immediate 
      post-operative period.
