BACKGROUND: In contrast to the timing of coronary angiography and percutaneous coronary intervention, the optimal timing of coronary artery bypass grafting (CABG) in non-ST-elevation myocardial infarction (NSTEMI) has not been determined. Therefore, we compared in-hospital outcomes according to different time intervals to CABG surgery in a contemporary NSTEMI population in the USA. METHOD(S): We identified all NSTEMI hospitalizations from 2016 to 2020 where revascularization was performed with CABG. We excluded NSTEMI with high-risk features using prespecified criteria. CABG was stratified into 120 h from admission. Outcomes of interest included in-hospital mortality, perioperative complications, length of stay (LOS), and hospital cost. RESULT(S): A total of 147 170 NSTEMI hospitalizations where CABG was performed were assessed. A greater percentage of females, Blacks, and Hispanics experienced delays to CABG surgery. No difference in in-hospital mortality was observed, but CABG at 72-120 h and at >120 h was associated with higher odds of non-home discharge and acute kidney injury compared with CABG at 120 h was associated with higher odds of gastrointestinal hemorrhage and need for blood transfusion. All 3 groups with CABG delayed >24 h had longer LOS and hospital-associated costs compared with hospitalizations where CABG was performed at
