Preoperative Chronic Kidney Disease as a Strong Predictor of Postoperative Infection and Mortality After Coronary Artery Bypass Grafting

摘要: BACKGROUND The aim of this study was to determine the influence preoperative kidney dysfunction (ie, chronic disease (CKD)) on postoperative cardiovascular events, infection, acute injury and hospital mortality in patients undergoing coronary artery bypass grafting (CABG). METHODS AND RESULTS: A multi-institutional retrospective performed at 14 hospitals adult isolated CABG from 2007 2008 (n=1,522). We classified CKD level according estimated glomerular filtration rate (eGFR): normal, eGFR >90 ml·min(-1)·1.73 m(-2); mild, 60-90 moderate, 30-59 severe, <30 m(-2), assessed outcome. Preoperative distribution as follows: n=121 (8%); n=713 (47%); n=515 (34%); n=169 (11%). Risk infection strongly correlated with (normal, 3.3%; 7.0%; 8.3%; 17.0%; P<0.01). risk in-hospital death also 1.7%; 1.0%; 1.6%; 5.9%; On multivariate logistic regression analysis, identified a significant factor for injury, death. CONCLUSIONS Advanced is strong predictor after CABG.
