Purpose: 

Many patients with coronary artery disease (CAD) do not achieve the recommended physical activity (PA) levels during and after cardiac rehabilitation (CR). The aim of this study was to analyze moderate to vigorous physical activity (MVPA) levels and the differences between perceived (self-reported) and measured (activity monitor) MVPA in CAD patients during CR. The second aim was to analyze which patient characteristics were associated with this difference.

Methods: 

A two-center observational-sectional study was conducted within the Department of Rehabilitation Medicine of the University Medical Center Groningen between January and April 2018. Adults with CAD, following an outpatient CR program, were included. Perceived MVPA was assessed with the Short Questionnaire to Assess Health-enhancing Physical Activity and compared with ActivPAL3 activity monitor outcomes over a period of 7 d.

Results: 

Fifty-one patients with CAD (age 59.4 ± 7.1 yr, eight females) were recruited. Four patients (8%) did not achieve the recommended guideline level of ≥150 min/wk of MVPA. Patients spent ≥80% of the week in sedentary activities. Patients overestimated MVPA with a median of 805 (218, 1363) min/wk (P< .001). The selected patient characteristics (age, body mass index, type of CAD, type of CR, social support, and self-efficacy) were not associated with this overestimation.

Conclusions: 

Most patients with CAD, participating in an outpatient CR program, do achieve MVPA exercise recommendations but spend simultaneously too much time in sedentary activities.

门诊心脏康复期间的自我报告与测量的体力活动水平

目的： 

许多冠状动脉疾病 (CAD) 患者在心脏康复 (CR) 期间和之后没有达到建议的体力活动 (PA) 水平。本研究的目的是分析 CAD 患者 CR 期间中度至剧烈体力活动 (MVPA) 水平以及感知（自我报告）和测量（活动监测）MVPA 之间的差异。第二个目的是分析哪些患者特征与这种差异相关。

方法： 

格罗宁根大学医学中心康复医学系于 2018 年 1 月至 4 月期间进行了一项两中心观察性截面研究。纳入了接受门诊 CR 计划的患有 CAD 的成年人。使用评估健康增强身体活动的简短问卷评估感知的 MVPA，并与 7 天期间的 ActivPAL3 活动监测结果进行比较。

结果： 

招募了 51 名 CAD 患者（年龄 59.4 ± 7.1 岁，8 名女性）。4 名患者 (8%) 未达到 MVPA ≥150 分钟/周的推荐指南水平。患者每周有 80% 以上的时间进行久坐活动。患者高估了 MVPA，中位数为 805 (218, 1363) 分钟/周 ( P < .001)。所选患者特征（年龄、体重指数、CAD 类型、CR 类型、社会支持和自我效能）与这种高估无关。

结论： 

大多数参加门诊 CR 计划的 CAD 患者确实达到了 MVPA 运动建议，但同时花费太多时间进行久坐活动。
