Abstract

Objective Patients with inflammatory rheumatic diseases have an increased risk of developing coronary atherosclerosis. However, outcomes of surgical revascularization in these patients have been rarely studied. We aimed to determine whether, or which, inflammatory rheumatic diseases may pose effects on mortality and adverse cardiac outcomes after coronary artery bypass grafting. Methods By using the National Health Insurance Research Database of Taiwan, we identified 40,639 adult patients who underwent first-time coronary artery bypass grafting between 2000 and 2010. Among these patients, 101 had rheumatoid arthritis, 56 had systemic lupus erythematosus, and 73 had ankylosing spondylitis. The odds ratios (ORs) of operative mortality and hazard ratios (HRs) of overall mortality and adverse cardiac outcomes after coronary artery bypass grafting (ie, myocardial infarction and repeat revascularization) in relation to rheumatoid arthritis, systemic lupus erythematosus, and ankylosing spondylitis were estimated. Results With adjustment for potential confounders including patient characteristics, hospital levels, and combined surgery, systemic lupus erythematosus was an independent predictor for operative mortality (adjusted OR, 2.63; 95% confidence interval [CI], 1.04-6.65; P =.04) and ankylosing spondylitis was marginally associated with operative mortality (adjusted OR, 2.41; 95% CI, 0.99-5.88; P =.054). Systemic lupus erythematosus was a significantly independent predictor for overall mortality during the follow-up period (adjusted HR, 2.23; 95% CI, 1.51-3.31; P <.0001) and might increase the risk of repeat revascularization (adjusted HR, 1.89; 95% CI, 0.97-3.68; P =.06). Neither rheumatoid arthritis nor ankylosing spondylitis was significantly associated with overall mortality and adverse cardiac outcomes. Conclusions Our study may help surgeons and physicians recognize the potential risks inherent to systemic lupus erythematosus and ankylosing spondylitis when conducting coronary artery bypass grafting and providing follow-up care.
