The risk assessment of elective spine fusion patients with a previous history of cardiac intervention, particularly a coronary artery bypass graft (CABG), has been understudied. This study aimed to assess postoperative outcomes of elective spine fusion patients with a prior history of single- to multilevel coronary artery bypass grafting. Investigate effect of revascularization on 30-day and 90-day outcomes in elective spine fusion patients. Retrospective review of the PearlDiver database between the years 2006-2013. A total of 733,007 elective spine fusion patients. Comorbidity burden, 30-day and 90-day complications (myocardial infarction, pneumonia, sepsis, death, would complications, transfusions), readmission. Elective spine fusion patients were isolated with ICD-9 and CPT procedures codes in the PearlDiver database. Patients were stratified by number of coronary arteries grafted during a coronary artery bypass grafting procedure prior to spine fusion: (1) 1-2 grafts (G12); (2) 3-4 grafts (G34); (3) no grafts. Means comparison tests compared differences in demographics, diagnoses, comorbidities, and 30-day complication outcomes. Logistic regression assessed the odds of complication associated with number of arteries grafted, controlling for levels fused, age, sex, and comorbidities (odds ratio [95% confidence interval]). A total of 733,007 elective spine fusion patients were isolated;723,606 pts had no grafts, 5,356 were G12, and 4,045 were G34. G12 patients at baseline had higher rates of morbid obesity, PVD, chronic kidney disease, CHF, and COPD (p
