title: The role of cystatin C in the prognosis of adverse outcomes after the coronary artery bypass graft surgery during hospitalisation.
abstract: BACKGROUND
  This study has been aimed to assess clinical significance of cystatin C in the prognosis of a risk of hospital complications among the patients with coronary artery disease CAD who have undergone coronary artery bypass surgery (CABG).
  
  
  METHODS
  We have recruited 719 consecutive Caucasian (Russian) patients who underwent CABG in 2011-2012.
  
  
  RESULTS
  No statistically significant differences in the serum creatinine concentration (sCr) and glomerular filtration rate before and seven days after the surgery have been found among the patients belonging to different EuroSCORE risk groups. A statistically significant elevation of serum cystatin C concentration (sCC) before and seven days after the surgery has been demonstrated in EuroSCORE medium- and high-risk groups in comparison with the low-risk group. In addition, we have revealed increased pre-surgical levels of sCC in patients who had died earlier than seven days after CABG. Regarding the cardiovascular complications, a statistically significant elevation of sCC has been observed in patients with and without myocardial infarction (MI), stroke, or acute kidney injury (AKI) in the postoperative period.
  
  
  CONCLUSIONS
  We suggest that the determination of sCC before and after CABG surgery may help in the prognosis of adverse cardiovascular and renal outcomes after the CABG surgery.
