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(-1) x kg x 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.
这项亚组分析的目的是，在一项针对65岁及以上冠状动脉搭桥术患者的大型母研究中的女性参与者（N = 40）中，检验症状管理（SM）干预对术后症状评估、身体功能和身体活动的影响。干预组（n = 23）在6周时疲劳评分显著更低（Z = 1.96，P < .05），且身体活动水平更高（Z = -1.71，P < .05），这通过冠状动脉搭桥术后3个月时活动日记测得的千卡消耗（-1）x千克x天（-1）来反映。在术后6周和3个月时，心脏手术相关恢复症状（呼吸急促、疲劳、抑郁、切口疼痛和睡眠问题）与身体功能（身体、活力和身体疼痛功能分量表评分）之间存在显著相关性，相关系数范围为0.31至0.46。鉴于这是一项更大规模研究的亚组分析，预计并非所有变量都会有显著差异。研究结果支持需要一种有针对性（以女性为重点）且量身定制（自我管理恢复）的干预措施，以帮助女性从冠状动脉搭桥手术中恢复，改善症状管理，从而提高身体功能和身体活动结果。
