The purpose of this subset analysis was to examine the effect of a symptom management (SM) intervention on postoperative symptom evaluation, physical functioning, and physical activity among the female participants (N = 40) of the larger parent study of coronary artery bypass graft patients aged 65 years and older. The intervention group (n = 23) had significantly lower fatigue scores at 6 weeks (Z = 1.96, P < .05) and higher levels of physical activity (Z = −1.71, P < .05) reflected in the expended kcal · kg−1 · d−1, as measured by the activity diary at 3 months after coronary artery bypass graft surgery. At 6 weeks and 3 months after surgery, there were significant correlations between cardiac surgery-related recovery symptoms (shortness of breath, fatigue, depression, incision pain, and sleep problems) and physical functioning (physical, vitality, and bodily pain functioning subscale scores), with correlations ranging from 0.31 to 0.46. Given that this was a subset analysis of a larger study, significant differences were not expected for all variables. Study findings support the need for a targeted (women-focused) and tailored (self-management recovery) intervention to assist females in recovering from coronary artery bypass graft surgery to improve symptom management, thereby enhancing physical functioning and physical activity outcomes.
