title: Analysis of clinical outcomes of intra-aortic balloon pump during coronary artery bypass surgery.
abstract: OBJECTIVE
  The mortality rate in coronary artery bypass surgery increases with advancing patient age. This study was conducted to analyse and compare older (above 65 years of age) with younger patients (below 65 years of age) who had undergone coronary artery bypass surgery and had an intra-aortic balloon pump (IABP) inserted, comparing hospital stay, clinical features, intensive care unit stay, postoperative complications, and morbidity and mortality rates.
  
  
  METHODS
  One hundred and ninety patients who had undergone coronary artery bypass surgery and required IABP support were enrolled in this study. Patients younger than 65 years of age were considered young, and the others were considered old. Ninety-two patients were young and 98 were old. The mortality rates, pre-operative clinical characteristics, postoperative complications, and duration of intensive care unit and hospital stays of the groups were compared. The risk factors for mortality and complications were analysed.
  
  
  RESULTS
  One hundred and thirty-eight of the patients were male, and the mean patient age was 62.7 ± 9.9 years. The mortality rate was higher in the older patient group than the younger group [34 (37.7%) and 23 (23.4 %), respectively (p = 0.043)]. The cross-clamp time, mean ejection fraction, cardiopulmonary bypass time, and length of stay in the intensive care unit were similar among the groups (p > 0.05). Cardiopulmonary bypass time was the single independent risk factor for mortality in both groups.
  
  
  CONCLUSIONS
  In this study, high mortality rates in the postoperative period were similar to prior studies regarding IABP support. The complication rates were higher in the older patient group. Prolonged cardiopulmonary bypass and advanced age were determined to be significant risk factors for mortality.
