目的 探讨小组赋权干预对冠心病经皮冠状动脉介入治疗术后患者自我损耗的影响。 方法 选取承德市某三级甲等医院心内科88例冠心病经皮冠状动脉介入治疗患者,随机分为试验组（n=44）和对照组（n=44）。对照组给予常规护理措施和随访指导,试验组在此基础上施行小组赋权干预。采用冠心病自我管理行为量表、自我调节疲劳量表于干预前、干预1个月、3个月后对两组进行调查。 结果 自我管理总分组间与时间存在交互效应（F_交互=37.286,P<0.001）,简单效应分析显示,干预1个月、3个月后,试验组得分高于对照组（t=2.545、3.038,P<0.05）。自我调节总分组间与时间存在交互效应（F_交互=313.787,P<0.001）,简单效应分析显示,干预1个月、3个月后,试验组得分高于对照组（t=2.394、6.780,P<0.05）。结论 小组赋权干预能有效降低冠心病介入治疗术后患者自我损耗程度,提高其自我管理水平。

Objective To investigate the effect of group intervention based on empowerment theory on ego depletion in patients with coronary heart disease after percutaneous coronary intervention（PCI）. Methods 88 patients with coronary heart disease after PCI in the Department of Cardiology of a third-level first-class hospital in Chengde city were randomly divided into the experimental group（n=44） and the control group（n=44）.The control group was given routine nursing measures and follow-up guidance,and the experimental group was given empowerment group intervention measures on this basis. Coronary artery disease Self-management Scale and Self-regulating Fatigue Scale were used to investigate the two groups before the intervention,1 month and 3 months after the intervention. Results There was an interaction effect between group and time regarding the total score of self-management（F_interaction=37.286,P<0.001). Simple effect analysis showed that the scores of the experimental group were significantly higher than those of the control group 1 month and 3 months after the intervention,（t=2.545、3.038,P<0.05). There was an interaction effect between the group and time regarding the total score of self-regulation（F_interaction=313.787,P<0.001）. Simple effect analysis showed that the scores of the experimental group were also significantly higher than those of the control group 1 month and 3 months after the intervention（t=2.394, 6.780,P<0.05). Conclusion The group empowerment can effectively reduce the degree of ego depletion in patients with coronary heart disease after PCI and improve their level of self-management.
