title: Predictors of long-term change in functional status after coronary artery bypass graft surgery in women.
abstract: A cohort of 164 women who had undergone coronary artery bypass graft surgery (CABG) was followed for one year to examine changes in functional status and determine the relative influence of clinical, psychosocial and sociodemographic factors on change in functional status outcomes between 6 and 12 months after surgery. Clinical, psychosocial, sociodemographic and preoperative functional status data were collected by written questionnaire and personal interview at the time of surgery and again at 6 and 12 months after CABG. Functional status scores improved significantly from before to 6 months after CABG. Between 6 and 12 months post-CABG 65% sustained or continued to experience improvement in physical functioning, 83% in social and leisure activities, and 54% in psychological functioning. Predictors of sustained improvement in physical functioning were being married, younger age, low 6-month functioning, having an ejection fraction of 50% or greater, and being white. The significant predictors of sustained improvement in social and leisure activities and psychological functioning were being married and low 6-month psychological functioning, respectively. These data suggest that interventions to improve long-term outcomes in women undergoing CABG should take into account not only their age, functional capacity and level of functioning at 6 months post-CABG, but also their race and marital status as potential risk factors for long-term functional status disability.
