title: [Effects of peri-operative intra-aortic balloon pump support in high EuroSCORE patients undergoing cardiac surgery].
abstract: OBJECTIVE
  To analyze the effects of perioperative intra-aortic balloon pump (IABP) support in EuroSCORE high-risk patients undergoing cardiac surgery, and evaluate the risk factors associated with mortality and midterm survival.
  
  
  METHODS
  Fifty-eight patients with EuroSCORE of no less than 6 underwent cardiac surgery and received peri-operative IABP support, including 29 with preoperative IABP support, 21 with intra-operative IABP support, and 8 with postoperative IABP support. The patients who survived the surgeries were followed up for at least 1 year.
  
  
  RESULTS
  Complications related to IABP support occurred in 2 cases (3.45%). The in-hospital mortality was 6.89% (4/58) in this series. Patients with intra-operative IABP had a lower ejection fraction, and those with pre-operative IABP showed more frequent unstable angina and recent myocardial infarction. The number of emergency procedures was also significantly higher in patients with pre-operative IABP support. Patients with intra- or postoperative IABP support had a longer ICU stay. The 1-year follow-up was completed in 54 patients and 4 deaths were recorded, with a 1-year survival of 86.21%. The 1-year survival rate was significantly higher in patients with preo- and intra-operative IABP support than those with post-operative IABP.
  
  
  CONCLUSIONS
  Peri-operative IABP support benefit cardiac support for cardiac surgery, and its preoperative use does not increase the surgical risk. Early prophylactic IABP support according to the EuroSCORE can improve the outcome of the high-risk cardiac surgery.
