Introduction: Our aim was to record preoperative and postoperative results in patients undergoing coronary artery bypass grafting, to examine the factors affecting reoperation, and to determine whether there is a gender difference in pre- and post-activity activity using the Duke Activity Status Index.

Material and Methods: 151 patients who underwent isolated coronary artery bypass grafting. The median time from baseline to return to work after Duke Success for women and men was 8.0 months. In addition to baseline scores at postoperative follow-up, the effects of 47 variables were analyzed with logistic ordinal models. The appropriate model for subsequent scores was determined by reverse selection, keeping the variables if they met the criteria for a P-value less than 0.05.

Results: Average scores on the Duke Activity Status Index (women, 21.5; men, 32.2; P < .001) and pretest scores (42.7 for women; 58.2 for men; P < .001) were lower in women than in men. Postoperative scores were lower in elderly patients with obstructive pulmonary disease, myocardial infarction, stroke, diabetes, vascular disease, severe postoperative pain, and return to the operating room. After adjusting for these factors, recovery scores remained lower for women (difference from men, 2.1 [95% confidence interval, 1.7-2.6]; P < .001).

Conclusion: A number of preoperative, surgical variables, and postoperative factors are associated with functional recovery after coronary revascularization. Additionally, after adjusting for these variables, female sexuality was later associated with lower performance.
