Yu PJ, et al. - In this retrospective study, researchers focused on the preoperative variables that were related to increased postoperative length of hospital stay or operative mortality in patients with severely depressed left ventricular ejection fraction (LVEF, ie, ≤ 25%) who underwent isolated coronary artery bypass grafting (CABG) between January 2012 and March 2017. They found that discharge was possible within 7 days postoperatively in more than half of the patients with severely depressed LVEF undergoing isolated CABG. The variables that were found to be related to more complicated or slower postoperative recovery post-CABG were: the absence of preoperative beta-blockers, low preoperative albumin levels, and higher Society of Thoracic Surgeons Predicted Risk of Mortality score.
