Secondary Outcome Measures:

Occurence of any component of the composite outcome [ Time Frame: Postoperative hospital discharge, 3 months, 12 months ] [ Designated as safety issue: No ]
length of stay on the intensive care unit [ Time Frame: Postoperative during hospital stay ] [ Designated as safety issue: No ]
total hospital stay [ Time Frame: hospital discharge ] [ Designated as safety issue: No ]
new onset of atrial fibrillation [ Time Frame: In-hospital ] [ Designated as safety issue: No ]
Delirium [ Time Frame: Postoperative 24, 48, 72, 96 hrs ] [ Designated as safety issue: No ]

Arms	Assigned Interventions
Active Comparator: RIPC	Procedure: Remote Ischemic Preconditioning RIPC will be induced during anesthesia by four 5-min cycles of upper limb ischemia and 5-min reperfusion using a blood-pressure cuff inflated to a pressure 200 mm Hg, whereas the pressure has to be at least 20 mm Hg greater than the systolic arterial pressure measured via the arterial line.
Sham Comparator: CONTROL	Procedure: Control/sham procedure (blood pressure cuff) Sham placement of the blood pressure cuff around a dummy arm inflated to a pressure of 200 mm Hg with four cycles of 5 min inflation and 5 min deflation.

Detailed Description:

Cardiac surgery with cardiopulmonary bypass is associated with a predictable incidence of myocardial, neurological and renal dysfunction. This significant morbidity and mortality is at least partly due to perioperative ischaemia. Remote ischaemic preconditioning (RIPC) is a novel, simple, non-invasive and inexpensive intervention by which ischaemia of non-vital tissue (skeletal muscles) protects remote organs (heart, brain and kidney) from a subsequent sustained episode of ischaemia. The investigators perform a multicenter randomized controlled study to evaluate that RIPC reduces teh severity of perioperative ischaemic injury in patients undergoing cardiac surgery, and results in about 1/3 risk reduction in the occurence of major adverse events.
