基于IMB模型的护理干预在冠心病PCI后Ⅱ期心脏康复患者中的应用效果

Application effect of nursing intervention based on IMB model in patients with stageⅡcardiac rehabilitation after PCI for coronary heart disease

目的探究基于信息-动机-行为技巧(IMB)模型的护理干预在冠心病经皮冠状动脉介入术(PCI)后Ⅱ期心脏康复患者中的应用效果。方法选择2020年1月至12月于本院进行Ⅱ期心脏康复的84例冠心病PCI后患者为研究对象,根据随机抽签法将其分为对照组(42例,常规康复运动)和研究组(42例,在对照组基础上开展基于IMB模型的护理干预)。比较两组的干预效果。结果干预后,研究组的冠心病康复知识、二级预防行为、运动自我效能评分高于对照组(P<0.05)。干预后,研究组的最大运动负荷(MWL)、无氧阈(AT)、左室射血分数(LVEF)和6 min步行试验(6MWT)高于对照组(P<0.05)。研究组的不良心血管事件(MACE)总发生率低于对照组(P<0.05)。结论基于IMB模型的护理干预在PCI后Ⅱ期心脏康复患者中的应用效果良好,能有效提高其健康知识水平和疾病自我管理能力,增强心肺功能,减少MACE。

Objective To explore the application effect of nursing intervention based on information-motivation-behavioral skills(IMB)model in patients with stageⅡcardiac rehabilitation after percutaneous coronary intervention(PCI)for coronary heart disease.Methods A total of 84 patients with coronary heart disease after PCI who underwent stageⅡcardiac rehabilitation in our hospital from January to December 2020 were selected as the research objects.According to the random lottery method,the patients were divided into control group(42 cases,routine rehabilitation exercise)and study group(42 cases,nursing intervention based on IMB model based on the basis of the control group).The intervention effects of the two groups were compared.Results After intervention,the scores of coronary heart disease rehabilitation knowledge,secondary prevention behavior and exercise self-efficacy in the study group were higher than those in the control group(P<0.05).After intervention,the maximal work load(MWL),anaerobic threshold(AT),left ventricular ejection fraction(LVEF)and 6 min walk test(6MWT)in the study group were higher than those in the control group(P<0.05).The total incidence of major adverse cardiovascular events(MACE)in the study group was lower than that in the control group(P<0.05).Conclusion The nursing intervention based on IMB model has a good application effect in patients with stageⅡcardiac rehabilitation after PCI,which can effectively improve health knowledge level and disease self-management ability,enhance cardiopulmonary function,and reduce MACE.
