Exclusion of patients with pulmonary fibrosis by using HRCT. Traditional CVD risk factors and disease characteristics and their correlation with VO2 max were assessed.Results: Based on VO2 max mean, patients were classified into three groups; unfit (<16.72 ml/kg/min), fair (16.73-25.6 ml/kg/min) and average fitness (>25.6 ml/kg/min). Patients were significantly worse VO2 max mean [(21.28±6.96) ml/kg/min] compared to control subjects. Patients with poor VO2 max level were more likely be older, hypertensive, had family history of CVD, high BMI with high mean of FRS. Significant differences were detected between the fitness subgroups in mean of carotid IMT and presence of carotid plaques. Long duration of RA, uncontrolled disease activity, high HAQ, high CRP and positive anti-CCP antibodies were correlated significantly with reduced VO2 max.Conclusion: VO2 max test can be used as a surrogate cardiovascular disease marker in RA patients. VO2 max can be used as a noninvasive test to detect and quantify fitness defects in RA patients at increased risk of CVD.FootnotesCite this article as Eur Respir J 2022; 60: Suppl. 66, 40.This article was presented at the 2022 ERS International Congress, in session “-”.This is an ERS International Congress abstract.
