Key result
Cardiac rehabilitation patients overestimate moderate to vigorous physical activity by ~800 minutes weekly compared to monitors.
Why the study?
Many patients with coronary artery disease do not achieve recommended physical activity levels during and after cardiac rehabilitation, and differences between self-reported and measured activity are unclear.
Observational (n=51)
Yes
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.

Helco G. van Keeken (2021) conducted an observational in Coronary artery disease (CAD) (n=51). Self-reported physical activity (SQUASH questionnaire) vs. Measured physical activity (ActivPAL3 activity monitor) was evaluated on Difference between perceived (self-reported) and measured moderate to vigorous physical activity (MVPA) (Median overestimation of 805 min/wk, p=<0.001). Patients with coronary artery disease in cardiac rehabilitation significantly overestimated their moderate to vigorous physical activity by a median of 805 minutes per week compared to activity monitors.
