Description
Summary:	Patients on double antiplatelet treatment who need early in-hospital coronary artery bypass grafting (CABG) are at high risk of major bleeding. In this study, we aimed to investigate the impact of ticagrelor preloading on CABG related bleeding in patients with ST-segment elevation myocardial infarction (STEMI) initially managed with primary percutaneous coronary intervention (pPCI). Patients with the diagnosis of STEMI who were managed with pPCI and underwent subsequent early (4-7 days following pPCI) or delayed (> 7 days following pPCI) on-pump CABG surgery were included. All study patients were preloaded with ticagrelor 180 mg prior to pPCI procedure. Patients' demographics, clinical variables, and short-term cardiovascular outcomes were recorded. This is a retrospective study which included 98 patients. Fifty-four (54%) patients underwent early and 44 (45%) patients underwent delayed CABG surgery. CABG-related bleeding occurred in 22 (22.4%) patients. There was no significant difference with respect to total ticagrelor dose and timing of the surgery between patients with or without CABG-related bleeding (p: 0.165 and p: 0.142). Multivariate analyses demonstrated that only preoperative hemoglobin level < 10.9 and use of mechanical cardiac support devices were independent predictors of CABG-related bleeding [OR: 3719, p: 0.009 and OR: 11,698, p: 0.004, respectively].There were three deaths within the 30 days of surgery, all occurring in patients with CABG-related bleeding. However, CABG-related bleeding was not associated with long-term cardiovascular events during the follow-up. Our results indicated that discontinuation of ticagrelor therapy 3 days prior to surgery is sufficient to avoid CABG-related bleeding. Moreover, early CABG following STEMI does not increase the risk of long-term cardiovascular events.
