Abstract

Abstract: Introduction: Patients with pulmonary hypertension (PH) show no symptoms at rest, but symptoms are triggered by physical activities. Objectives: The primary aim of our study was to assess physical activity of patients with PH by using an activity monitor. The secondary aim was to evaluate the correlation between the activity monitor parameters and 6‐min walk distance (6MWD), activity of daily living (ADL), quality of life, WHO functional class and PH classification. Methods: Thirty‐eight patients with pulmonary arterial hypertension (PAH) and seven patients with chronic thromboembolic PH were included in the study. Physical activity was assessed using a SenseWear arm band. A 6‐min walk test was performed. Daily living activities were assessed using the 'nottingham extended activity of daily living index' (NEADL). For quality of life assessments, 'Minnesota living with heart failure' (MLHF) and 'Short form‐36' (SF‐36) surveys were used. Results: Physical activity, exercise capacity, quality of life and contribution to ADL were lower in patients with PH. These data were associated with the 6MWD, quality of life and ADL index scores. We also found weak and moderate correlations between activity monitor data and SF‐36 sub‐group scores, MLHF and NEADL scores ( P < 0.05). For the group with PAH, idiopathic PAH patients had more exercise capacity and total energy expenditure compared with patients with scleroderma‐associated PAH. Conclusion: Correlation between activity monitor data and 6MWD, most of SF‐36 sub‐group scores, MLHF scores and NEADL index scores suggest that activity monitor can be used in the evaluation of patients with PH.
