To investigate the long-term outcomes of coronary artery bypass grafting surgery (CABG) in patients with rheumatoid arthritis (RA).
Patients with RA (
Diagnosis of RA was associated with an increased risk of mortality after CABG compared to patients without RA (HR 1.50; CI 1.28-1.77; 
RA is independently associated with worse prognosis in coronary artery disease treated with CABG. Preoperative corticosteroid use and longer RA disease duration are additional risk factors for mortality.Key messagesPatients with rheumatoid arthritis (RA) have impaired long-term outcomes after coronary artery bypass surgery (CABG).Glucocorticoid use before CABG and duration of RA are associated with higher mortality.Special attention should be paid in secondary prevention of cardiovascular disease in RA patients after CABG.
