Rapid CABG trial supports early surgical strategy 2-3 days after ticagrelor cessation in ACS management

Ticagrelor continues to be one of the often-used antiplatelet drugs in the management of acute coronary syndrome (ACS), however only 10% of the ACS patients treated with ticagrelor require coronary artery bypass surgery (CABG) due to perioperative bleeding.1 The current North American guidelines (Including ACC/AHA) advocate a waiting period of at least 5 days after ticagrelor cessation prior to non-urgent CABG, and the 2017 European Society of Cardiology (ESC) guidelines also recommend a waiting period of at least 3 days after ticagrelor cessation for non-urgent CABG. However, from the real-life clinical point of view, it is hypothesized that early surgery is noninferior to delayed surgery for severe or massive perioperative bleeding. Therefore, the RAPID CABG trial, a physician initiated multi-centre randomized study, was conducted to evaluate the safety of early CABG surgery after a shorter ticagrelor cessation of 2 to 3 days as compared to 5 to 7 days prior CABG, among 143 patients presenting with ACS who require non emergent CABG.1 Primary endpoint was severe/ massive bleeding by the Universal Definition of Perioperative Bleeding (UDPB): Class 3 or 4.

The results from a 6-month follow-up of RAPID CABG trial indicated patients could discontinue ticagrelor 2 to 3 days prior to CABG without increasing the risk of early post-surgical bleeding and could also reduce the average length of hospital stay.
