Resumen
Aim
Current physical activity guidelines often rely on self-reported or short-term device-based monitoring. We analysed long-term activity data via acceleration and continuous optical heart rate measurement and hypothesised a temporal association between volume and intensity and health-related outcomes in heart failure.
Methods
This prospective observational trial reanalysed longitudinal data from 156 patients with heart failure at baseline, 6 months, and 12 months. A multisensory activity tracker captured daily step count and continuous heart rate data over a 1-min sampling interval from patients with New York Heart Association (NYHA) Class I (n = 66) and Class II/III (n = 90) over 12 months. Linear mixed-effects models and univariate linear regression models were used to assess the associations between step count, moderate physical activity (MPA) and vigorous physical activity (VPA) and health-related outcomes [cardiorespiratory fitness, body composition, systemic inflammation levels, N-terminal pro brain natriuretic peptide (NTproBNP), and Kansas City Cardiomyopathy Questionnaire (KCCQ)].
