Original Article


We hypothesized that poor quality of life may lead to the development of post-operative hyperglycemia, as it is more likely to be associated with stress-induced impairment of glucose control. A correlation between the components of quality of life, and blood glucose changes after Coronary Artery Bypass Surgery (CABG) was examined. In a cross-sectional study, 268 consecutive patients undergoing CABG at Tehran Heart Center were recruited. Postoperative blood glucose were measured every 2 to 4 h for 24 h following surgery. Quality of life was assessed using the SF-36 questionnaire, and the physical and mental component summary scores were used to analyze data. An adverse relationship was found between mental summary score and the mean of plasma glucose concentrations during 24 h after surgery (β = −0.152, SE = 0.076, P = 0.046). No significant association was found between physical summary score and mean of plasma glucose concentration during this time. Postoperative blood glucose changes may be independently associated with patients’ mental status preoperative, as reflected by mental component of quality of life.
