Key result
CAD-specific accelerometer cut-points estimated significantly higher time spent in moderate-to-vigorous physical activity compared to cut-points for healthy young (mean difference 13.0 minutes/day) or middle-aged adults.
Why the study?
Do accelerometer cut-points developed for coronary artery disease patients yield different estimates of moderate-to-vigorous physical activity compared to cut-points for younger/middle-aged adults in CAD patients?
Cross-Sectional (n=231)
Yes

Accelerometer cut-points specific to coronary artery disease patients yield significantly higher estimates of moderate-to-vigorous physical activity compared to standard cut-points, highlighting the need for population-specific validation.
Prince et al. (2015) conducted a cross-sectional in Coronary Artery Disease (n=231). CAD-specific accelerometer cut-points (Mark) vs. Healthy young (Sasaki) and middle-aged (Santos-Lozano) cut-points was evaluated on Average time spent in bouts of moderate-to-vigorous intensity physical activity (MVPA) (MD 13.0 minutes/day, p=<0.0001). CAD-specific accelerometer cut-points estimated significantly higher time spent in moderate-to-vigorous physical activity compared to cut-points for healthy young (mean difference 13.0 minutes/day) or middle-aged adults.
