Background and Aim of the Study Intra‐aortic balloon pump (IABP) is the most commonly used device for circulatory support of patients with heart disease. The aim of this study evaluated the risk factors for outcomes of patients who underwent isolated coronary bypass grafting and received IABP. Methods One hundred‐seventy‐seven patients underwent isolated coronary bypass grafting and received intraoperative IABP. All perioperative data were recorded. The primary end‐point was in‐hospital mortality, while the secondary end‐points were the length of intensive care unit (ICU) stay and hospital length of stay (LOS). Results In‐hospital mortality was 5.6% (10 patients). Multivariable logistic regression analysis showed that the risk factors for in‐hospital mortality were preoperative plasma creatinine level and cardiopulmonary bypass (CPB) time (for both p < .05). Multivariable linear regression analysis showed that postoperative acute kidney injury (AKI), immediate plasma troponin after operation, numbers of grafts, and CPB time were predicted the hospital LOS, while postoperative AKI, preoperative left ventricular ejection fraction, and immediate plasma troponin after operation were predicted the lengths of ICU stay. Conclusion Our analysis showed that increased preoperative plasma creatinine, postoperative renal dysfunction, and CPB time negatively affected the outcomes of patients who received intraoperative IABP insertion.
