Exercise intervention on cardiorespiratory fitness in rheumatoid arthritis patients with high cardiovascular disease risk: a single-arm pilot study

Rehabilitation of patients with inflammatory rheumatic diseases and comorbidities: unmet needs

Comorbidities may contribute to inadequate response to therapy and accelerate disability in various rheumatic diseases such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and psoriatic arthritis (PsA). Cardiovascular, oncological, and infectious comorbidities are common in rheumatic patients. The rehabilitation of patients with inflammatory rheumatic diseases (IRDs) with comorbidities requires a multidisciplinary approach to improving patients' functional mobility, slowing down the disease progression and minimizing the risks of complications. The evidence suggests that cardiac rehabilitation can be implemented in daily practice in patients with IRDs to reduce mortality for those with established risk factors. Physical exercises reduce the severity, improve the clinical course, and reduce hospitalization rates in patients with rheumatic diseases. A rehabilitation program with focused physical therapy can lead to functional improvements and reduction of disease activity in patients with lowered quality of life (QoL). Health professionals should provide evidence-based recommendations for patients with rheumatic diseases and comorbidities to initiate the self-management of their diseases and prevent complications.

Effect of high-intensity interval training in physiotherapy primary care for patients with inflammatory arthritis: the ExeHeart randomised controlled trial

OBJECTIVES

To assess the effect of high-intensity interval training (HIIT) delivered in physiotherapy primary care on the primary outcome of cardiorespiratory fitness (CRF) in patients with inflammatory arthritis (IA). Additionally, to explore the effects of HIIT on secondary outcomes, including cardiovascular disease (CVD) risk factors and disease activity.

METHODS

Single-blinded randomised controlled trial with 60 patients randomly assigned to either a control group receiving usual care or an exercise group receiving usual care and 12 weeks of individualised HIIT at 90%-95% peak heart rate. Outcomes were assessed at baseline, 3 months and 6 months post baseline and included CRF measured as peak oxygen uptake (VO2peak), classic CVD risk factors, disease activity, anthropometry and patient-reported physical activity, pain, fatigue, disease impact and exercise beliefs and self-efficacy.

RESULTS

Intention-to-treat analysis demonstrated a significant between-group difference in VO2peak at 3 months (2.5 mL/kg/min, 95% CI 0.9 to 4.0) and 6 months (2.6 mL/kg/min, 95% CI 0.8 to 4.3) in favour of the exercise group. A beneficial change in self-reported physical activity in favour of the exercise group was observed at 3 and 6 months. The HIIT intervention was well-tolerated with minimal adverse events and no apparent impact on disease activity. Differences in secondary outcomes related to CVD risk factors, disease impact, pain, fatigue and exercise beliefs and self-efficacy were generally small and non-significant.

CONCLUSION

After 12 weeks of supervised HIIT delivered in physiotherapy primary care, patients with IA demonstrated a favourable improvement in CRF, with sustained effects at 6-month follow-up.

Exercise therapy for improving cardiovascular health in rheumatoid arthritis

There is increased risk of cardiovascular disease in patients with rheumatoid arthritis. Primary cardiovascular disease prevention in rheumatoid arthritis patients is difficult, especially in those with high disease activity. According to current evidence, people with rheumatoid arthritis can significantly improve clinical indices and patient-reported outcomes by engaging in organized physical activity such as resistance training and aerobic activities. Additionally, participating in an exercise regimen can lower the risk of experiencing cardiovascular problems. Nevertheless, the percentage of patients with sedentary lifestyle habits is high among individuals with rheumatoid arthritis. Patient education regarding the benefits of physical activity/exercise is essential. The cardiovascular effects of exercise depend on several mechanisms such as (i) increased vascular function, (ii) decreased systemic inflammation, (iii) restoration of the autonomic system, (iv) improved lipid profile, and (v) increased muscular function. Maintaining the exercise routine is crucial for continuing benefits. A customized exercise plan helps to improve adherence and compliance. Engaging patients in shared decision-making is important since their personal choices can alter depending on several factors such as the severity of the disease, the cost, and accessibility. The current narrative review aimed to explore the recent evidence related to exercise therapy for cardiovascular health in patients with rheumatoid arthritis.

Remotely Supervised Weight Loss and Exercise Training to Improve Rheumatoid Arthritis Cardiovascular Risk: Rationale and Design of the Supervised Weight Loss Plus Exercise Training-Rheumatoid Arthritis Trial

Patients with rheumatoid arthritis (RA) remain at an increased risk for cardiovascular disease (CVD) and mortality. RA CVD results from a combination of traditional risk factors and RA-related systemic inflammation. One hypothetical means of improving overall RA CVD risk is through reduction of excess body weight and increased physical activity. Together, weight loss and physical activity can improve traditional cardiometabolic health through fat mass loss, while also improving skeletal muscle health. Additionally, disease-related CVD risk may improve as both fat mass loss and exercise reduce systemic inflammation. To explore this hypothesis, 26 older persons with RA and overweight/obesity will be randomized to 16 weeks of a usual care control arm or to a remotely Supervised Weight Loss Plus Exercise Training (SWET) program. A caloric restriction diet (targeting 7% weight loss) will occur via a dietitian-led intervention, with weekly weigh-ins and group support sessions. Exercise training will consist of both aerobic training (150 minutes/week moderate-to-vigorous exercise) and resistance training (twice weekly). The SWET remote program will be delivered via a combination of video conference, the study YouTube channel, and study mobile applications. The primary cardiometabolic outcome is the metabolic syndrome Z score, calculated from blood pressure, waist circumference, high-density lipoprotein cholesterol, triglycerides, and glucose. RA-specific CVD risk will be assessed with measures of systemic inflammation, disease activity, patient-reported outcomes, and immune cell function. The SWET-RA trial will be the first to assess whether a remotely supervised, combined lifestyle intervention improves cardiometabolic health in an at-risk population of older individuals with RA and overweight/obesity.

Patient perspective on exercise intervention in rheumatoid arthritis with high risk of cardiovascular disease: a pilot qualitative study

The objective of the study was to gain an insight into the perceptions and experiences of patients with rheumatoid arthritis and a high cardiovascular disease risk (CVD-RA) when undergoing an exercise intervention aimed at improving their cardiorespiratory fitness. This qualitative study was part of a pilot study, which investigated the effects of an exercise intervention on cardiorespiratory fitness in patients with CVD-RA. Six patients were invited to participate in face-to-face semi-structured interviews. We invited patients who completed the exercise intervention as well as patients who withdrew from the exercise intervention. The interviews were analyzed according to the method of thematic analysis. Six patients were interviewed, of whom four patients completed and two patients discontinued the exercise intervention. The mean (SD) age was 58 (9.7) years, the median disease duration was 10 years, and five patients were female. The analyses revealed seven themes that provided insight into perceptions and experiences: (1) ability to understand reasons for actions; (2) the need to be seen; (3) reaching their maximum effort; (4) experiencing their limits; (5) wanting personalized exercise therapy; (6) happy to be physically active; (7) benefits of exercise. Patients perceived that they were able to perform a cardiopulmonary exercise test with maximum effort and achieved the prescribed intensity of the exercise intervention. They also experienced an improvement in their physical activity by incorporating physical activity in their daily live. Overarching principles that re-occurred in the themes were: the need to be viewed as a person and the importance of feeling safe.
