行为转变理论干预对冠心病患者动脉狭窄程度、体征及生活方式和质量影响

Effects of transtheoretical model of behavior intervention on arterial stenosis degree,signs,lifestyle and quality of life in patients with coronary heart disease

目的:探索基于行为转变理论的干预措施对冠心病患者动脉狭窄程度、症状、生命体征、生活方式和生活质量的影响。方法:选择2019年10月~2022年12月我院收治的126例冠心病患者并随机分为对照组、研究组,每组63例。所有患者均给予基础护理,包括用药指导、心理干预等,研究组联合应用基于行为转变理论的干预措施,两组均持续干预3个月。比较两组患者干预前后的动脉狭窄程度、临床症状、体征、生活方式和生活质量。结果:与对照组比较,干预后研究组左室射血分数(LVEF)[(46.84±2.09)%比(52.87±2.44)%]、健康促进生活方式量表Ⅱ(HPLP-Ⅱ)[(105.73±8.79)分比(133.05±9.87)分]、生活质量综合评定问卷-74(GQOLI-74)[(179.72±4.28)分比(195.02±4.11)分]与西雅图心绞痛量表(SAQ)[(71.16±4.35)分比(88.68±10.82)分]评分均显著升高,左室舒张末容积(LVEDV)[(72.50±3.25)ml比(66.81±3.70)ml]、左室舒张末内径(LVEDd)[(50.76±2.81)mm比(43.48±2.27)mm]和Gensini积分[(28.39±1.64)分比(21.41±2.05)分]均显著降低,P均=0.001。结论:基于行为转变理论干预能够显著改善冠心病患者动脉狭窄程度、临床症状和体征,促进患者健康生活方式的养成,提高生活质量。

Objective:To explore the effects of transtheoretical model of behavior intervention on the degree of arterial stenosis,symptoms,vital signs,lifestyle and quality of life(QOL)in patients with coronary heart disease(CHD).Methods:A total of 126 CHD patients admitted to our hospital from October 2019 to December 2022 were selected and randomly divided into control group and study group,with 63 cases in each group.All patients were given basic nursing,including medication guidance,psychological intervention etc.The study group received additional intervention based on transtheoretical model of behavior.Both groups were intervened for 3 months.Dcgrce of arterial stenosis,inical symptoms,signs,lifestyle and QOL were compared between the two groups before and after intervention.Results:Compared with control group,there were significant rise in left ventricular ejection fraction(LVEF)[(46.84±2.09)%vs.(52.87±2.44)%],scores of health promoting lifestyle profile Ⅱ(HPLP-Ⅱ)[(105.73±8.79)points vs.(133.05±9.87)points],general quality of life inventory-74(GQOLI-74)[(179.72±4.28)points vs.(195.02±4.11)points]and Seattle angina questionnaire(SAQ)[(71.16±4.35)points vs.(88.68±10.82)points],and significant reductions in left ventricular end-diastolic volume(LVEDV)[(72.50±3.25)ml vs.(66.81±3.70)ml],left ventricular end-diastolic diameter(LVEDd)[(50.76±2.81)mm vs.(43.48±2.27)mm]and Gensini score[(28.39±1.64)points vs.(21.41±2.05)points]in study group after intervention,P=0.001 all.Conclusion:Transtheoretical model of behavior intervention can significantly improve the degree of arterial stenosis,clinical symptoms and signs,promote the development of healthy lifestyle and improve quality of life in patients with coronary heart disease.
