Exercise Self-Efficacy and patient global assessment were associated with 6-min walk test distance in persons with rheumatoid arthritis

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.

The Association Between Rheumatoid Arthritis and Atrial Fibrillation: Epidemiology, Pathophysiology and Management

Atrial fibrillation (AF) is the most common cardiac arrhythmia with a significant increase in morbidity and mortality worldwide. Rheumatoid arthritis (RA), as a systemic inflammatory disease, affecting 0.5-1.0% of the adult population, is associated with increased incidence of cardiac arrhythmias such as AF. Several epidemiologic studies find that the risk of AF is increased in RA when compared with the general population. Other studies are inconsistent. Considering that inflammation plays an important role in AF, RA may be involved in the occurrence and development of AF. This review summarizes the epidemiology, pathophysiology, and management of AF in patients with RA.

The association between rheumatoid arthritis and reduced estimated cardiorespiratory fitness is mediated by physical symptoms and negative emotions: a cross-sectional study

OBJECTIVES

Persons with rheumatoid arthritis (RA) have lower cardiorespiratory fitness (CRF) than healthy individuals. We sought to identify variables explaining the association between RA status and reduced CRF.

METHODS

RA patients recruited from two Norwegian hospitals and blood donors recruited as controls filled in questionnaires about physical activity, physical symptoms, and psychological factors. Estimated CRF (eCRF) was calculated from non-exercise models. The relationship between RA status and reduced eCRF was explored with structural equation modelling. The latent variables physical symptoms (based on morning stiffness, joint pain, and pain in neck, back, or hips) and negative emotions (based on Hospital Anxiety and Depression Scale's Depression score and Cohen's perceived stress scale) were included as possible mediators between RA status and eCRF in separate and combined models adjusted for age and sex.

RESULTS

Two-hundred-and-twenty-seven RA patients and 300 controls participated. The patients were older and had lower eCRF than controls (age- and sex-adjusted mean difference: 1.7 mL/kg/min, p=0.002). Both latent variables were significant mediators of the association between RA and reduced eCRF when included in separate models. The latent variables mediated 74% of the total effect of RA on eCRF in the combined model. Standardized coefficients: direct effect of RA -0.024 (p=0.46), indirect effect through physical symptoms -0.034 (p=0.051), and indirect effect through negative emotions -0.034 (p=0.039).

CONCLUSION

Both physical symptoms and negative emotions mediated the association between RA and reduced eCRF with similar effect sizes. To successfully increase CRF in RA patients, both physical and psychological factors should be addressed. Key Points • The RA patients in the present study had 1.7 mL/kg/min lower mean estimated cardiorespiratory fitness (CRF) compared to healthy controls. • Mediation analysis demonstrated that physical symptoms and negative emotions mediated 74% of the total negative effect of RA on estimated CRF in a combined, adjusted model. • This suggests that both physical and psychological factors should be addressed when supporting RA patients in improving their CRF.

Persons with rheumatoid arthritis have higher barriers to physical activity than controls: a cross-sectional study using the Facilitators and Barriers to Physical Activity Questionnaire (FasBarPAQ)

Facilitators and barriers to performing physical activity (PA) may vary among persons with rheumatoid arthritis (RA) as well as between RA patients and healthy individuals. Primary objective: To investigate associations of presence of RA and levels of stress and depression with scores for facilitators and barriers to PA, using a new questionnaire (FasBarPAQ). Secondary objectives: investigate inter-individual score differences in persons with RA, and associations with RA disease-specific variables. Persons with RA from two outpatient clinics (n = 203) and blood donor controls (n = 293) filled in the new 14-item FasBarPAQ questionnaire, the Hospital Anxiety and Depression Scale depression scale (HADS-D), Cohen's perceived stress scale, and questions regarding PA. Clinical data, and self-reported disease activity and physical function were collected for the persons with RA. Data were analyzed using linear and logistic regression. RA was associated with lower Facilitators scores (coefficient = - 1.30, p = 0.015), higher Barriers scores (coefficient = 2.36, p < 0.001) and lower Total Facilitators-Barriers scores (coefficient = - 3.67, p < 0.001). HADS-D ≥ 8 was associated with lower Total scores (coefficient = - 3.32, p = 0.022), and the two higher stress score tertiles were associated with higher Barriers and lower Total scores (p = 0.023 to p < 0.001). Persons with RA reported greatly varying facilitators and barriers profiles. Seropositivity and higher patient global assessment were associated with higher Barriers scores (coefficients = 1.79, p = 0.011; 0.60, p < 0.001) and lower Total scores (coefficients = - 3.60, p = 0.003; - 0.98, p < 0.001). Persons with RA had higher barriers and lower facilitators for PA, with varying individual profiles. The new FasBarPAQ questionnaire may be a useful screening tool for healthcare providers treating persons with RA.
