Patients with rheumatoid arthritis (RA) appear to be at increased risk of venous thromboembolism when compared with those who did not have RA, according to a Mayo Clinic study. Rates of cerebrovascular and peripheral arterial events, however, were similar between the groups. The authors added that the incidence of non-cardiac vascular disease has been stable in recent decades in patients with RA.
