Brief summary
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.
Interventions
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.
Patients will have a automated inflator cuff placed on the upper arm during surgery which will not be inflated.
