Active Comparator
Placebo Comparator
RIPC
Control
Remote ischemic preconditioning (RIPC) protocol before coronary artery bypass surgery consists of 3 cycles of 5 minutes left upper arm ischemia by inflation of a blood pressure cuff to 200 mmHg and 5 minutes of reperfusion after induction of anesthesia before coronary artery bypass surgery. For myocardial molecular analyses, left ventricular biopsies are taken before induction of cardioplegic cardiac arrest and 5 and 10 Minutes after aortic unclamping during reperfusion of the myocardium.
Control group: Coronary artery bypass surgery without remote ischemic preconditioning protocol
