What’s new
1- New bleeding prediction scores are needed for isolated coronary bypass operations.
2- Although it causes vascular pathologies; we couldn’t find relations between postoperative bleeding and DM
3-The bleeding scores examined in this study were insufficient to calculate the risk of postoperative bleeding in patients with DM.
Examination of variables that can be intervened by the clinician such as htc, creatinine, platelet in the preoperative period may decrease the postoperative bleeding level.
