  Purpose

Recent studies indicate that remote ischemic conditioning can protect the heart and other organs during cardiac surgery. The investigators aim to investigate whether such a stimulus can reduce the incidence of atrial fibrillation or other complications following coronary artery bypass surgery.

Arms Assigned Interventions
Experimental: Preconditioning
The remote ischemic stimulus will be applied after induction of anaesthesia, but before cardiopulmonary bypass.
Procedure: Remote ischemic conditioning
Patients will have a automated inflator cuff placed on the upper arm during surgery. The cuff will be used to induce fore arm ischemia by inflation to 200 mmHg for 3 x 5 minutes, interspersed with 5 minutes of no-inflation and thus reperfusion.
Other Names:
  • Remote ischemic conditioning
  • Remote ischemic preconditioning
  • Remote ischemic postconditioning
Experimental: Postconditioning
The remote ischemic stimulus during cardiopulmonary bypass.
Procedure: Remote ischemic conditioning
Patients will have a automated inflator cuff placed on the upper arm during surgery. The cuff will be used to induce fore arm ischemia by inflation to 200 mmHg for 3 x 5 minutes, interspersed with 5 minutes of no-inflation and thus reperfusion.
Other Names:
  • Remote ischemic conditioning
  • Remote ischemic preconditioning
  • Remote ischemic postconditioning
Experimental: Pre and postconditioning
The remote ischemic stimulus will be applied twice, after induction of anaesthesia and during cardiopulmonary bypass.
Procedure: Remote ischemic conditioning
Patients will have a automated inflator cuff placed on the upper arm during surgery. The cuff will be used to induce fore arm ischemia by inflation to 200 mmHg for 3 x 5 minutes, interspersed with 5 minutes of no-inflation and thus reperfusion.
Other Names:
  • Remote ischemic conditioning
  • Remote ischemic preconditioning
  • Remote ischemic postconditioning
Sham Comparator: Control Procedure: Sham
Patients will have a automated inflator cuff placed on the upper arm during surgery which will not be inflated.
