Short-term outcomes following coronary artery bypass graft surgery in insulin treated and non-insulin treated diabetes: A tertiary hospital experience in Australia

Outcomes after coronary artery bypass graft (CABG) surgery have improved due to advances in surgical technique and post-operative care. We aimed to describe contemporary clinical characteristics and short-term post-operative outcomes in diabetic patients undergoing CABG surgery.A retrospective analysis of patients who underwent CABG surgery over a 4.5-year period in a Western Australian tertiary hospital was performed in September 2019. The cohort was stratified according to pre-operative diabetes status.A total of 1327 patients underwent CABG surgery, of which 572 (43.1%) had diabetes. Diabetic patients were more likely to be female (24.7% vs. 13.9%, p 0.001) and have dyslipidaemia (83.0% vs. 68.1%, p 0.001), hypertension (82.0% vs. 68.7%, p 0.001), raised body mass index (29.8 ± 5.6 vs. 28.7 ± 5.1 kg/mDiabetic patients continue to represent a higher-risk cohort, highlighting the need for further strategies to reduce short-term adverse outcomes following CABG surgery.
