Abstract

Objectives: The purpose was to establish uniaxial and triaxial accelerometer cut-points denoting moderate and vigorous intensity physical activity (PA) among coronary artery disease patients based on relative exercise intensity. Methods: Eighteen coronary artery disease patients (Age: 58 ± 11 yr) wore an ActiGraph GT3X accelerometer during a cardiac stress test.  Exercise intensity was measured at each stage. Receiver operator characteristic curve analyses were used to establish cut-points. Results: Uniaxial count ranges of 750-2299 and ≥2300 counts∙min-1 were found to best identify moderate and vigorous intensity PA, respectively. Triaxial count ranges of 1800-3799 and ≥3800 counts∙min-1 were found to best identify moderate and vigorous intensity PA, respectively. Cut-points were found to be lower than those for both middle-aged and older adults. Conclusion: Cut-points specific to coronary artery disease patients should be used rather than generic points established for healthy middle-aged and older adults.
