title: A 6-Year Single-Center Experience of Intra-aortic Balloon Pump Treatment--Retrospective Analysis of 223 Patients.
abstract: OBJECTIVE
  This study describes the long-term survival (1 year) of patients after intra-aortic balloon pump (IAPB) treatment.
  
  
  METHODS
  A single-center, retrospective registry study.
  
  
  METHODS
  Single university hospital intensive care unit.
  
  
  METHODS
  Participants included 223 consecutive patients who received intra-aortic balloon pump (IABP) treatment between January 1, 2005, and December 31, 2010 (203 cardiac surgical patients [7.8% of all cardiac surgical patients] and 20 conservative medical patients).
  
  
  METHODS
  IABP treatment was used as an adjunct therapy for severe hemodynamic compromise perioperatively in cardiac surgery and in hemodynamic shock of other etiology.
  
  
  RESULTS
  Mean age of patients was 66±10 years. The 30-day mortality was 22.1% for surgical patients and 37.8% for conservative medical patients. The 1-year mortality was 24.5% for surgical patients and 55% for conservative medical patients. There were 14 (6.3%) major complications related to IABP treatment that required operative treatment. The 1-year survival for patients surviving the initial 30 days after coronary artery bypass grafting was 95.2%. Independent predictors of 1-year mortality (Cox regression) were age, previous cardiac surgery, critical preoperative state, and conservative medical treatment. Timing (preoperative, intraoperative, postoperative) of IABP treatment did not predict survival.
  
  
  CONCLUSIONS
  IABP treatment was safe with few serious complications. Timing of IABP placement was not related to survival. Survival at 1-year follow-up was excellent after an initially high mortality for cardiac surgical patients treated for hemodynamic compromise with aortic counterpulsation.
