title: Evaluation of the reliability of the EuroSCORE risk analysis prediction in high-risk older patients undergoing CABG.
abstract: BACKGROUND
  The aim of this prospective study was to evaluate the reliability of EuroSCORE risk-analysis predictions on early mortality in high-risk older patients who underwent heart surgery.
  
  
  METHODS
  From January 2008 to February 2009, a total of 128 consecutive high-risk older patients who underwent open-heart surgery were included. Patients who required emergency surgery, had pulmonary hypertension, a recent myocardial infarction, underwent combined heart surgery procedures or had renal disease were included. The patients had a mean age of 72 +/- 9 years (range 64-91, 53.1% male) and were evaluated for surgery.
  
  
  RESULTS
  Coronary artery bypass graft (CABG) surgery was performed on 112 patients and valve surgery on 16. Eight patients (6.25% ) died in hospital. The observed mortality rate was lower than the expected mortality obtained using EuroSCORE (6.25% vs 11.2 +/- 7.2%, respectively, p < 0.021).
  
  
  CONCLUSIONS
  There was no correlation between the preoperative logarithmic score of expected mortality and the observed mortality rate in these older high-risk patients who underwent open-heart surgery.
