Brief Summary:
Due to advances and increased practice of interventional therapy for coronary artery disease, the rate of high-risk patients with severe coronary disease and reduced left ventricular function among patients undergoing coronary artery bypass grafting surgery (CABG) is increasing. The perioperative mortality in these patients is ≥ 5%. The perioperative and operative management for these patients has to be optimized in order to reduce their perioperative morbidity and mortality. One of the central aspects is perioperative maintenance of hemodynamic stability. The use of prophylactic IABP is a partly established, but not sufficiently evidence-based measure to reduce ventricular afterload and improve coronary perfusion pre-, intra- and postoperatively. Yet, it is an invasive procedure with potential complications. The planned trial should give an explicit answer, whether preoperative prophylactic IABP decreases 30-day all-cause mortality (primary endpoint) and long-term mortality (3, 6, 12 months; secondary endpoints) compared to preoperative conservative treatment in high-risk patients undergoing CABG.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 200 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Prophylactic Preoperative Inatraaortic Balloon Pump (IABP) in High-risk Patients Undergoing Coronary Artery Bypass Surgery (CABG)
Study Start Date : June 2015
Estimated Primary Completion Date : February 2017
Estimated Study Completion Date : February 2018

Arm Intervention/treatment
Experimental: IABP group
Preoperative IABP insertion
Procedure: Preoperative IABC
IABP-Insertion upon inclusion into the trial and admission to the ICU

No Intervention: Control group
Preoperative conservative treatment



Primary Outcome Measures :
  1. 30-day all-cause mortality post CABG [%] [ Time Frame: 30 days ]

Secondary Outcome Measures :
  1. Survival at 3, 6, 12 months [%] [ Time Frame: 3, 6 and 12 months ]
  2. Duration of ICU stay [h] [ Time Frame: 48 hours (average) ]
  3. Dependence on medical inotropic support [ Time Frame: 48 hours (average) ]
  4. IABP-associated complications [ Time Frame: 8 days (average) ]
    IABP-associated complications occur most often during IABP-support. However, after weaning from IABP, patients can still have bleeding complications or thrombembolic complications. Therefore, IABP-associated complications are monitored during the whole hospital stay
