BACKGROUND Rheumatoid arthritis (RA) is associated with increased cardiovascular risk. METHODS To assess the role of exercise echocardiography (EE) in the evaluation of patients with RA, follow-up (mean, 6.7+/-3.7 years) was retrospectively obtained in 159 patients with RA who underwent EE. Patients were matched for age, gender, and cardiovascular risk factors with 454 controls who underwent EE. RESULTS Patients with RA were more likely to have positive results for ischemia on EE (odds ratio, 2.32; 95% confidence interval, 1.48-3.64; P=.0003). Rest and exercise wall motion score indexes were higher in the RA group (1.14+/-0.33 and 1.22+/-0.39, respectively, vs 1.06+/-0.18 and 1.10+/-0.24 in controls; P < .005 for each). Logistic regression adjusted for age revealed an increased odds ratio for myocardial ischemia of 1.06 (95% confidence interval, 1.02-1.11; P=.005) per year of RA. Five-year all-cause mortality in subjects with RA with myocardial ischemia on EE was 14.9%, compared with 4.3% in RA subjects without ischemia (P=.028). CONCLUSIONS RA was associated with a 2-fold increased risk for myocardial ischemia on EE; risk increased with the duration of RA. Mortality was increased in patients with RA with ischemia on EE.

D001172 Arthritis, Rheumatoid A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated. Rheumatoid Arthritis
D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D012307 Risk Factors An aspect of personal behavior or lifestyle, environmental exposure, inborn or inherited characteristic, which, based on epidemiological evidence, is known to be associated with a health-related condition considered important to prevent.

D016015 Logistic Models Statistical models which describe the relationship between a qualitative dependent variable (that is, one which can take only certain discrete values, such as the presence or absence of a disease) and an independent variable. A common application is in epidemiology for estimating an individual's risk (probability of a disease) as a function of a given risk factor.

D016022 Case-Control Studies Comparisons that start with the identification of persons with the disease or outcome of interest and a control (comparison, referent) group without the disease or outcome of interest. The relationship of an attribute is examined by comparing both groups with regard to the frequency or levels of outcome over time.
