Maile MD, Mathis MR, Habib RH, et al. - Given that decreased left ventricular ejection fraction (LVEF) represents a recognized risk factor for complications following coronary artery bypass grafting (CABG), but relevance of higher LVEF values has not been established, therefore, researchers performed this single-centre retrospective cohort study to determine the link between preoperative LVEF values and short- and long-term results post-CABG applying a strategy that permitted for the identification of nonlinear associations. As per their hypothesis, there exists an independent association of both higher and lower values with increased postoperative complications as well as death in this population. Participants were patients receiving isolated CABG surgery (n = 7,932). All participants underwent a preoperative measurement of their LVEF. According to the findings, an increased risk may be present in relation to higher preoperative LVEF values in patients undergoing CABG surgery.
