Coronary artery disease remains a major cause of mortality and morbidity with systemic lupus erythematosus (SLE). We report two cases of coronary artery bypass grafting (CABG) associated with SLE. The first patient (a 45-year-old woman) underwent CABG operation for left main and two-vessel coronary disease using cardiopulmonary bypass. Successful CABG was done using off-pump technique in the second patient (a 39-year-old woman) under hemodialysis therapy. Both patients showed good postoperative outcome without complications.
