Abstract
Objective: In patients with rheumatoid arthritis (RA) with cardiovascular disease risk, it is unknown whether exercises are safe, improve cardiorespiratory fitness and reduce disease-related symptoms and cardiovascular-disease (CVD) risk factors. We aimed to investigate in RA patients with CVD risk: (1) safety of medium to high-intensity aerobic exercises, (2) potential changes of cardiorespiratory fitness and (3) disease activity and CVD risk factors in response to the exercises. Methods: Single-arm pilot-exercise intervention study including 26 consecutive patients (21 women) with > 4% 10-year risk of CVD mortality according to the Dutch Systematic Coronary Risk Evaluation. Aerobic exercises consisted of two supervised-sessions and five home-sessions per week for 12 weeks. Patients were required to exercise at intensities between 65 and 85% of their maximum heart rate. To assess safety, we recorded exercise related adverse events. Before and after the exercises, cardiorespiratory fitness was assessed with a graded maximal oxygen-uptake exercise test, while disease activity was evaluated via the Disease Activity Score-28 (DAS28) using the erythrocyte segmentation rate (ESR). Resting blood pressure, ESR and total cholesterol were assessed as CVD risk factors. Results: Twenty out of 26 patients performed the 12-week exercises without any adverse events. According to patients, withdrawals were unrelated to the exercises. Exercises increased cardiorespiratory fitness (pre: 15.91 vs. post: 18.15 ml.kg−1 min−1, p = 0.003) and decreased DAS28 (pre: 2.86 vs. post: 2.47, p = 0.04). No changes were detected in CVD risk factors. Conclusion: A 12-week exercise intervention seems to be safe and improves cardiorespiratory fitness and disease activity in patients with RA with a high risk for cardiovascular diseases.Key Points1. Rheumatoid arthritis patients with high cardiovascular disease risk were able to perform a maximum exercise test and a 12-week aerobic-based medium-to-high intensity exercise intervention.2. The exercise intervention improved cardiorespiratory fitness and disease activity in rheumatoid arthritis patients with high cardiovascular disease risk.3. Cardiorespiratory fitness levels were still low post-exercise intervention (i.e. 18.15 ml.kg−1min−1 compared to the 20.9 ml.kg−1min−1 baseline mean of the RA patients without CVD risk). © 2022, The Author(s), under exclusive licence to International League of Associations for Rheumatology (ILAR).
