The aim of this study was to: (i) test different instruments that focused on sleep, quality of life and personal adjustment in order to evaluate the usefulness of these instruments in a larger study; and (ii) to describe self perceptions of sleep and life situation by patients who had undergone coronary artery bypass grafting (CABG). A one-group pre-test repeated post-test design was used. Six men aged between 51 and 70 years were interviewed, and 24 h polysomnographic recordings were performed before and after the operation. The interviews indicated disturbed sleep and changes in behaviour and mental state immediately postoperatively. Postoperatively the polysomnographic recordings revealed a significant decrease in mean duration of sleep, mean percentage of stage 3-4 sleep and mean rapid eye movement (REM) sleep. One month after surgery the quality of life was improved, while moderate anxiety and sensation of incisional pain persisted. The measurements used in this pilot study provide valuable information into the understanding of altered sleep, quality of life and personal adjustment following CABG.
（i）测试专注于睡眠、生活质量和个人适应情况的不同工具，以便在更大规模的研究中评估这些工具的实用性；以及（ii）描述接受冠状动脉搭桥术（CABG）的患者对睡眠和生活状况的自我认知。采用单组前测重复后测设计。对6名年龄在51至70岁之间的男性进行了访谈，并在手术前后进行了24小时多导睡眠图记录。访谈表明术后即刻睡眠紊乱，行为和精神状态发生变化。术后多导睡眠图记录显示，平均睡眠时间、3-4期睡眠的平均百分比和平均快速眼动（REM）睡眠均显著下降。术后一个月生活质量有所改善，但中度焦虑和切口疼痛仍持续存在。本初步研究中使用的测量方法为理解冠状动脉搭桥术后睡眠改变、生活质量和个人适应情况提供了有价值的信息。
