"Objectives The aims of this paper were (1) to describe objectively confirmed physical activity patterns across 3 chronic cardiopulmonary conditions, and (2) to examine the relationship between selected physical activity dimensions with disease severity, self-reported physical and emotional functioning, and exercise performance. Design Cross-sectional study. Setting Participants' home environment. Participants Patients with cardiopulmonary illnesses: chronic obstructive pulmonary disease (COPD) (n=63), heart failure (n=60), and patients with implantable cardioverter defibrillator (n=60). Interventions Not applicable. Main Outcome Measures Seven ambulatory physical activity dimensions (total steps, percent time active, percent time ambulating at low, medium, and high intensity, maximum cadence for 30 continuous minutes, and peak performance) were measured with an accelerometer. Results Subjects with COPD had the lowest amount of ambulatory physical activity compared with subjects with heart failure and cardiac dysrhythmias (all 7 activity dimensions, P<.05 total step counts were: versus respectively. six-minute walk distance was correlated p with all physical activity dimensions in the copd sample strongest correlations being steps and peak performance. subjects cardiac impairment maximal oxygen consumption had only small to moderate of contrast between test were higher albeit a smaller patients heart failure. for samples self-reported mental health functioning age body mass index airflow obstruction ejection fraction either relatively or nonsignificant activity.> Conclusions All 7 dimensions of ambulatory physical activity discriminated between subjects with COPD, heart failure, and cardiac dysrhythmias. Depending on the research or clinical goal, use of 1 dimension, such as total steps, may be sufficient. Although physical activity had high correlations with performance on a 6-minute walk test relative to other variables, accelerometry-based physical activity monitoring provides unique, important information about real-world behavior in patients with cardiopulmonary illness not already captured with existing measures." |
