Changes in physical activity levels following different exercise modalities in patients with atrial fibrillation: a 1-year follow-up
Notice bibliographique
Résumé
Abstract Background Patients with atrial fibrillation (AF) demonstrate poor physical activity levels. Previous findings show that 56% of patients with AF do not meet the Canadian 24-Hour Movement Guidelines of ≥150min/wk of moderate-to-vigorous-intensity physical activity (MVPA). Exercise-based cardiovascular rehabilitation (CR), including moderate-to-vigorous intensity exercise training (MICT) and high-intensity interval training (HIIT), has been shown to improve key cardiovascular health outcomes, such as functional capacity, among adults with permanent and non-permanent AF. However, their long-term effects on MVPA levels in patients with AF remain unknown. Purpose To compare the long-term effects (i.e., up to 1 year) of 12 weeks of HIIT- and MICT-based CR on MVPA levels in patients with persistent and permanent AF. Methods Patients with AF who completed a randomized clinical trial of 12 weeks of MICT- (n = 23) or HIIT-based (n = 19) CR were followed for a 1-year observation phase. Physical activity was measured using a waist-worn accelerometer over 7 days at two separate time points (week 26 and year 1). Linear mixed models with repeated measures were used to assess the changes in physical activity levels over time and between the groups. The maximum likelihood estimation method to address missingness and an unstructured covariance matrix were used. A comparison of the proportion of patients meeting vs. not meeting the Canadian 24-Hour Movement Guidelines (≥150 min/wk of MVPA) was performed using Chi-square (χ2) analyses. A p-value of < 0.05 was set for statistical significance. Results This study included 42 participants with AF (57% diagnosed with permanent AF, mean age: 68.4 ± 7.2 years, 38% females). Significant main effects of time revealed decreases in MVPA between the end of the exercise intervention (week 12) and week 26 follow-up (-83.2 ± 19.3 min/wk, P = 0.001), not returning to week 12 MVPA levels following 1 year of completion (157.9 ± 14.1 min/wk vs. 129.7 ± 24.5 min/wk, P > 0.05). No significant main effect of group or time × group interaction was observed for MVPA levels. At week 26, no patients in the HIIT group (0%) and 3 (13%) in the MICT group met the Canadian 24-Hour Movement Guidelines (≥150 min/wk of MVPA), and no significant differences between groups were observed (χ2 = 1.25; P = 0.26). At year 1, 3 patients in the HIIT group (16%) and 1 (4%) in the MICT group met the Canadian 24-Hour Movement Guidelines, and no significant differences between groups were observed (χ2 = 2.36; P = 0.12). Conclusion MVPA levels decreased significantly following a 12-week exercise-based CR program in patients with persistent and permanent AF, irrespective of the exercise modality. Effective strategies are needed to increase and sustain MVPA levels after an exercise program in patients with AF.
