目的·评估冠状动脉粥样硬化性心脏病（冠心病）患者参加门诊心脏康复（cardiac rehabilitation，CR）的障碍水平现状并分析其相关因素。方法·采用方便抽样方法，于2017年10月—12月选取上海市杨浦区、虹口区、宝山区及松江区的7所三级甲等综合医院住院或门诊就诊的冠心病患者为研究对象。采用一般资料问卷、心脏康复相关信息知晓度调查问卷（Cardiac Rehabilitation Information Awareness Questionnaire，CRIAQ）及中文版心脏康复障碍量表（Chinese/Mandarin Cardiac Rehabilitation Barriers Scale，CRBS-C/M）进行调查，分析冠心病患者的CR信息知晓情况、CR障碍因素现状及相关因素。结果·共发放问卷390份，回收有效问卷342份，问卷有效回收率为87.7%。冠心病患者平均年龄（67.03±10.83）岁，听说过CR的患者为42人（12.3%）。CRBS-C/M的总均分中位数为3.10（2.71，3.43）分，各维度均分中位数介于3.00~3.50分，其中外部后勤因素障碍评分最高，为3.50（3.00，4.00）分；前3位的阻碍因素条目分别是“距离”“天气恶劣”和“我不知晓心脏康复”，同意或非常同意的患者比例分别为75.4%（258/342）、69.3%（237/342）和67.8%（232/342）。CRIAQ平均得分为（46.48±12.54）分。多元线性回归分析结果显示，CRIAQ得分（β=-0.242，P=0.000）、是否为不稳定型心绞痛（β=0.194，P=0.000）、性别（β=0.154，P=0.002）及是否参加门诊CR项目（β=-0.128，P=0.016）是冠心病患者CR障碍水平的相关因素（F=8.909，P=0.000），可解释总变异量的25.9%。结论·冠心病患者CR障碍处于中上水平，最大障碍因素是外部后勤因素；患者认为阻碍其参加CR的前3位原因分别是距离远、天气恶劣及不知晓CR。CR信息知晓度高、参加门诊CR项目患者的CR障碍水平较低，不稳定型心绞痛、女性患者的CR障碍的水平较高。

Objective ·To evaluate the current status of barriers to outpatient cardiac rehabilitation (CR) in patients with coronary heart disease (CHD) and analyze related factors. Methods ·From October to December 2017, the inpatients or outpatients with CHD from seven tertiary general hospitals in Yangpu District, Hongkou District, Baoshan District and Songjiang District of Shanghai were selected as the research objects by convenient sampling method. The general information questionnaire, the Cardiac Rehabilitation Information Awareness Questionnaire (CRIAQ) and the Chinese/Mandarin Cardiac Rehabilitation Barriers Scale (CRBS-C/M) were used to investigate the awareness of CR information, the barriers to CR and related factors in the patients with CHD. Results ·A total of 390 questionnaires were distributed, and 342 valid questionnaires were recovered, with an effective recovery rate of 87.7%. The average age of the CHD patients was (67.03±10.83) years old. Among them, 42 patients (12.3%) had heard of CR. The overall median score of CRBS-C/M was 3.10 (2.71, 3.43) points, and the median scores of five dimensions ranged from 3.00 to 3.50 points. The median score of external logistical factors was the highest, which was 3.50 (3.00, 4.00) points. The top three barriers were "distance" "severe weather" and "I did not know about cardiac rehabilitation", with 75.4% (258/342), 69.3% (237/342) and 67.8% (232/342) of the patients agreeing or strongly agreeing, respectively. The average score of CRIAQ was (46.48±12.54) points. Multiple linear regression analysis showed that CRIAQ score (β=-0.242, P=0.000), whether diagnosed as unstable angina or not (β=0.194, P=0.000), gender (β=0.154, P=0.002) and whether participating in outpatient CR programs or not (β=-0.128, P=0.016) were the related factors of CR barriers in the patients with CHD (F=8.909, P=0.000), which explained 25.9% of the total variation. Conclusion ·The CR barrier of the patients with CHD is in the upper middle level, and the biggest barrier factor is the external logistical factor. The top three reasons that patients think hindering their participation in CR are long distance, severe weather and not knowing about CR. The patients with high awareness of CR information, or participating in outpatient CR programs have a low level of CR barriers, while the patients with unstable angina pectoris or the female patients have a high level.
