Outcome Measures

Primary Outcomes (1)

  • occurrence and number of cerebral infarctions assessed by magnetic resonance imaging

    2-7 days after surgery

Secondary Outcomes (7)

  • mortality

    within hospital stay following surgery

  • stroke

    within hospital stay following surgery

  • delirium

    within hospital stay following surgery

  • neurocognitive performance

    within hospital stay following surgery

  • multi-organ failure

    within hospital stay following surgery

  • +2 more secondary outcomes

Study Arms (2)

1

EXPERIMENTAL
Procedure: OBCAB (Off Pump Coronary Artery Bypass Grafting)

2

ACTIVE COMPARATOR
Procedure: CABG (coronary artery bypass grafting)

Interventions

OPCAB with sparing of aortic manipulation (eg, no aortic cannulation for cardiopulmonary bypass, no aortic cross-clamp, no side-clamping of the aorta). Graft anastomosis to the central circulation with y-grafts on the arteria thoracica interna or on the aorta with help of the Heart-string-system (Guidant)

1

conventional CABG with cardiopulmonary bypass
