ObjectivePatients with rheumatoid arthritis have an increased risk for accelerated atherosclerosis. It is not known, however, whether this disorder is associated with a higher risk of complications after coronary artery revascularization.MethodsWe conducted a cross-sectional study of patients in the 2003-2005 Nationwide Inpatient Sample. To determine whether patients with rheumatoid arthritis had higher in-hospital mortality after coronary artery revascularization, we used logistic regression to adjust for age, sex, race/ethnicity, income, rural-urban residency, diabetes, hypertension, hyperlipidemia, Charlson comorbidities (including myocardial infarction, congestive heart failure, and diabetes), elective admission, weekend admission, and primary payer.ResultsAmong patients undergoing coronary artery revascularization, those with rheumatoid arthritis were 49% less likely to die while hospitalized compared with those without rheumatoid arthritis (odds ratio, 0.51; 95% confidence interval, 0.40-0.65) after adjusting for the above confounders. In subgroup analyses that adjusted for the same confounders, patients with rheumatoid arthritis also had a 61% improvement of in-patient mortality when they underwent percutaneous coronary interventions (odds ratio, 0.39; 95% confidence interval, 0.29-0.54) along with a median of 0.32 less days hospitalized (95% confidence interval, 0.28-0.34 days). Similarly, patients with rheumatoid arthritis undergoing coronary artery bypass grafting had a 31% improvement of in-patient mortality (odds ratio, 0.69; 95% confidence interval, 0.48-0.99), with a median of 1.36 less days hospitalized (95% confidence interval, 0.72-1.12 days).ConclusionAmong patients undergoing coronary artery revascularization, patients with rheumatoid arthritis have an in-hospital survival advantage along with reduced days of hospitalization compared with patients without rheumatoid arthritis.2010 The American Association for Thoracic Surgery.
