title: A risk score to predict 30-day mortality in patients with intra-aortic balloon pump implantation.
abstract: BACKGROUND
  Several risk factors for early mortality after intra-aortic balloon pump (IABP) implantation have been described.
  
  
  METHODS
  We performed a retrospective analysis in 120 patients receiving peri- or postoperative IABP support. Univariate and multivariate analyses were carried out to assess variables potentially influencing 30-day mortality in order to develop a risk score for the prognosis of survival and for the decision on optimal patient-specific treatment.
  
  
  RESULTS
  The 4 parameters (mean arterial pressure, adrenaline dose, central venous pressure, and blood lactate concentrations) at 6 hours of IABP use were independently related to 30-day mortality. They were used to develop a risk score (0 - 4 points). With this score, patients who scored 3 or 4 points had no probability of surviving, whereas patients with a score of zero had a probability of 84.4 %. A prospectively screened cohort of 145 patients confirmed the reliability of our risk score.
  
  
  CONCLUSIONS
  Our data demonstrate that a score can predict 30-day mortality in patients with IABP implantation. Such a score can be useful to find out whether or not ECMO/VAD implantation is necessary.
