| Summary: | The course of perioperative period in 719 patients undergoing CABG in the Research Institute for Complex Issues of Cardiovascular Diseases between March, 2011 and April, 2012 was evaluated. All the patients had creatinine concentrations, glomerular filtration rate (GFR by MDRD) and daily urine microalbumin levels measured before CABG and at day 7 after CABG. Major event rates were assessed (myocardial infarction, stroke or transient ischemic attack, acute or decompensated chronic renal failure or remediastinotomy) during the hospital stay. The EuroSCORE was calculated for each patient. Different EuroSCORE risk patients had similar serum creatinine levels while microalbumin concentrations in daily urine were significantly higher in moderate and high EuroSCORE risk groups before the surgery as compared to low-risk patients. Patients who experienced postoperative events had significantly higher microalbuminuria both before and after surgery while there were no differences in such renal dysfunction markers as creatinine and GFR. Preoperative microalbuminuria assessment can act as a marker of complicated postoperative period after CABG.
