In this study, I examined sleep, memory, and learning in off‐pump coronary artery bypass (OPCAB) patients. Sixty‐six men and women aged ≥60 years wore actigraphs to record sleep and completed sleep diaries for two 24‐hour periods following OPCAB surgery. Prior to discharge from the hospital, participants completed the Pittsburgh Sleep Quality Index (PSQI) and Rey Auditory Verbal Learning Test. No significant correlations were found between habitual sleep, sleep time, efficiency, number, and duration of awakenings, daytime napping, or memory and learning. Nighttime sleep was short with frequent disturbances, and daytime sleep accounted for half the daily sleep time. Participants scored low in learning and delayed recall. These findings suggest the need to assess sleep and cognition in patients recovering from OPCAB surgery. © 2005 Wiley Periodicals, Inc. Res Nurs Health 28:462–473, 2005
