目的·了解当前上海市冠心病（coronary heart disease，CHD）患者参与门诊心脏康复的现状并探讨其影响因素。方法·2017年10月—12月采用方便抽样抽取上海市7家三级甲等医院心血管内科门诊就诊的CHD患者为研究对象，采用一般资料问卷、中文版心脏康复障碍量表（Chinese/Mandarin Cardiac Rehabilitation Barriers Scale，CRBS-C/M）及心脏康复相关信息知晓度调查问卷（Cardiac Rehabilitation Information Awareness Questionnaire，CRIAQ）对其进行调研。采用单因素分析、Spearman相关分析以及结构方程模型对患者心脏康复信息、感知心脏康复障碍及门诊心脏康复参与行为三者之间的关系进行分析。结果·共发放问卷273份，回收有效问卷234份，有效回收率为85.7%。调查对象平均年龄（66.78±10.42）岁；仅17例（7.26%）患者自我报告出院后至少参加过1次门诊心脏康复。患者心脏康复参与比率在不同社会人口学特征上差异无统计学意义。Spearman相关分析显示患者的心脏康复相关信息知晓度、感知心脏康复障碍与其门诊心脏康复参与行为三者之间呈显著相关（均P=0.000）。路径分析显示心脏康复相关信息知晓度对门诊心脏康复参与行为具有直接促进作用（β=0.384，P=0.000）；感知心脏康复障碍在患者心脏康复信息知晓度与门诊心脏康复参与行为之间起部分中介作用。结论·CHD患者心脏康复信息知晓度可以直接促进其门诊心脏康复参与行为，也可以部分缓解患者感知心脏康复障碍对门诊心脏康复参与行为的不利作用。医务人员应从提升患者心脏康复相关信息着手，采取多种形式的健康教育，提高其心脏康复认知，减少患者感知的心脏康复障碍，最终促进CHD患者参与门诊心脏康复。

Objective ·To understand the current situation of outpatient cardiac rehabilitation participation of patients with coronary heart disease (CHD) in Shanghai and explore its influencing factors. Methods ·From October to December 2017, by using the convenience sampling method, a cross-sectional study was conducted to obtain information of CHD patients who visited the cardiovascular outpatient departments from 7 tertiary hospitals in Shanghai, concerning sociodemographics, Chinese/Mandarin Cardiac Rehabilitation Barriers Scale (CRBS-C/M) and Cardiac Rehabilitation Information Awareness Questionnaire (CRIAQ). The viarate analysis and Spearman analysis were applied to correlation analysis and the structural equation model was applied to path analysis. Results ·A total of 273 questionnaires were distributed and 234 valid questionnaires were collected with the effective rate of recovery at 85.7%. The average age of the respondents was (66.78±10.42) years. Only 17 (7.26%) patients self-reported that they participated in the outpatient cardiac rehabilitation at least once after discharge. There was no significant difference in participation rates in different sociodemographics. The Spearman correlation analysis demonstrated that cardiac rehabilitation information awareness, perceived cardiac rehabilitation barriers, and participation in outpatient cardiac rehabilitation were significantly correlated (all P=0.000). Path analysis showed that the cardiac rehabilitation information had a direct promoting effect on the behavior of participating in outpatient cardiac rehabilitation (β=0.384, P=0.000), and could also be partially mediated by cardiac rehabilitation barriers. Conclusion ·Regarding the patients with CHD, the awareness of cardiac rehabilitation information can directly promote their participation in outpatient cardiac rehabilitation, and can also partially alleviate the adverse effect of perceived cardiac rehabilitation barriers. Health care providers should start with improving patients' cardiac rehabilitation information and adopt various forms of health education to improve their cardiac rehabilitation cognition and overcome perceived cardiac rehabilitation barriers. Ultimately, the participation in outpatient cardiac rehabilitation programs will be facilitated for patients with CHD.
