Abstract

Objective: To determine whether the risk for cardiovascular and/or cerebrovascular disease (CCVD) is increased in rheumatoid arthritis (RA) compared to osteoarthritis (OA), a disease not known to be associated with increased CCVD.

Methods: In July 1999, a survey was administered to a sample of 11,572 patients (9,093 with RA, 2479 with OA) from the practices of 709 US community-based rheumatologists. Patients reported past and current myocardial infarction (MI), stroke (cerebrovascular accident, CVA), and lifetime congestive heart failure (CHF), and also provided demographic and clinical information. To estimate the impact of recall bias, medical records were obtained and reviewed for a 50% random sample of the patients reporting CCVD events, with 95% of CCVD reported events confirmed by record review.

Results: Patients with RA and OA differed across all demographic variables. In addition, each variable was significantly associated with MI, CHF, and CVA outcomes. Logistic regression was performed to measure the associations of these outcomes with RA as compared to OA, adjusting for age, sex, education level, smoking, income, hypertension, and body mass index. Compared with OA, patients with RA had the following increased risks: for current MI [odds ratio (OR), 95% confidence interval (95% CI)] 2.14, (1.48, 3.09), lifetime MI 1.28 (1.24, 1.33), CHF 1.43 (1.28, 1.59), current CVA 1.70 (1.29, 2.24), and lifetime CVA 1.005 (0.931, 1.196). The adjusted current and lifetime prevalences of MI were 0.76 and 4.14% for RA versus 0.35 and 3.23% respectively for OA; 0.86 and 3.02% (RA) versus 0.50 and 3.03% (OA) for CVA; and for lifetime CHF, 2.34% (RA) versus 1.64% (OA), respectively.

Conclusions: RA is associated with an increased risk for CCVD morbidity due to MI, CHF, and probably for CVA, and may be an independent risk factor for these events.
