Brief Summary:
Objectives: Despite utilization of available means for cardioprotection during cardiac surgery, myocardial injury still occurs. Further improvement of cardioprotection is therefore necessary. Remote ischemic preconditioning (RIPC) is an easy and non-invasive method. Laboratory research has shown promising results regarding myocardial survival during open heart surgery, but the clinical value of RIPC is still largely unknown. The investigators hypothesize that RIPC before coronary artery bypass grafting (CABG) reduces the incidence of postoperative atrial fibrillation (POAF).

Arm Intervention/treatment
Experimental: RIPC
Remote ischemic preconditioning (RIPC) in the operating theatre after induction of anaesthesia and before surgery.
Procedure: RIPC
The remote ischemic preconditioning will consist of three sequential sphygmomanometer cuff inflations. The cuff will be inflated up to 200 mmHg for 5 minutes and then deflated for 5 minutes. This cycle will be performed three times in total. The entire preconditioning will therefore last for 25 minutes.
Other Names:
  • Remote ischemic preconditioning
  • Ischemic preconditioning

No Intervention: No RIPC
Patients in the control group will not receive remote ischemic preconditioning before the surgery.

Primary Outcome Measures :
  1. Postoperative atrial fibrillation [ Time Frame: Up to 10 days after surgery ]
    A patient will be classified as belonging to the postoperative atrial fibrillation group if they have any episode of atrial fibrillation, measured by telemetry, lasting more than 1 minute during their postoperative days at the hospital.

Secondary Outcome Measures :
  1. Length of hospital stay [ Time Frame: Maximum 14 days ]
