The objective of the present study is to assess which respiratory symptoms and patient and disease characteristics are most highly associated with pulmonary function test PFT abnormalities in an RA patient cohort without clinical cardiovascular disease. Methods A total of 159 individuals with RA and without clinically evident cardiovascular disease were evaluated. Respiratory symptoms were assessed with the Lung Tissue Research Consortium questionnaire and all patients underwent evaluation with PFTs. Demographic lifestyle RA disease and treatment characteristics were collected. Subclinical coronary artery disease was assessed by cardiac computed tomography. Multivariable regression analysis was used to identify pulmonary symptoms and nonpulmonary parameters associated with PFT abnormalities. Areas under the receiver operating characteristic curves AUC were calculated to evaluate the discrimination of these variables for identifying patients with PFT abnormalities. Results Respiratory symptoms were reported by 42 of the patient population. Although only 6 carried a prior diagnosis of lung disease PFT abnormalities were identified in 28 of the subjects. Symptoms combined with other patient and RA characteristics body mass index current smoking anti-cyclic citrullinated peptide antibodies and current prednisone use performed satisfactorily in predicting the PFT abnormalities of obstruction AUC 95 confidence interval to
