目的:了解经皮冠状动脉支架植入（CASI）术后患者锻炼意向现状及其影响因素，以促进患者积极参与锻炼。方法:采用便利抽样法，选取2020年5—8月在山东省某三级甲等医院心内科门诊复诊的165例CASI术后患者为研究对象。使用一般资料调查表、锻炼意向量表、锻炼自我效能量表和锻炼社会支持量表进行调查。结果:本研究发放问卷165份，回收有效问卷154份，有效回收率93.33%。154例CASI术后患者锻炼意向量表得分为（12.46±4.05）分。多重线性回归分析结果显示，年龄、近1周中等强度活动量、心功能分级、锻炼自我效能和锻炼社会支持是CASI术后患者锻炼意向的影响因素（n P<0.05），共解释总变异的47.6%。n 结论:CASI术后患者的锻炼意向有待进一步提高，影响患者锻炼意向的因素较多。患者家属和医护人员应提供更多的锻炼支持，提高其锻炼自我效能感。“,”Objective:To understand the current situation and influencing factors of exercise intention among patients after percutaneous coronary artery stent implantation (CASI) , so as to promote patients to actively participate in exercise.Methods:Using the convenient sampling method, 165 patients with CASI who revisited in the cardiology department of a Class Ⅲ Grade A hospital in Shandong Province from May to August 2020 were selected as the research objects. General information questionnaire, Exercise Intention Scale, Exercise Self-efficacy Scale and Exercise Social Support Scale were used for investigation.Results:In this study, 165 questionnaires were distributed and 154 valid questionnaires were returned, with an effective recovery rate of 93.33%. The score of Exercise Intention Scale for 154 patients after CASI was (12.46±4.05) . The results of multiple linear regression analysis showed that age, moderate-intensity activity in the past week, classification of cardiac function, exercise self-efficacy and exercise social support were influencing factors of exercise intention among patients after CASI (n P<0.05) , which explained 47.6% of the total variation.n Conclusions:The exercise intention of patients after CASI needs to be further improved and there are many factors that affect exercise intention of patients. Family members of patients and medical staff should provide more exercise support to improve their exercise self-efficacy.
