  • Double- or triple-vessel coronary artery disease
  • Elective isolated first-time CABG
  • Combined valve surgery + CABG
  • Written informed consent

Exclusion Criteria:

Arm Label

RIPC

Control

Arm Description

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

Outcomes

Primary Outcome Measures

Perioperative extent of myocardial injury as measured by cardiac troponin I serum release over 72 hours after CABG surgery and its area under the curve (AUC).

Secondary Outcome Measures

All-cause mortality
Major adverse cardiac and cerebrovascular events (MACCE)
Myocardial infarction
Renal function

5. Study Description

Brief Summary
Remote ischemic preconditioning (RIPC) with transient upper limb ischemia/reperfusion reduces myocardial injury in patients undergoing on-pump coronary artery bypass (CABG) surgery with cross-clamp fibrillation or blood cardioplegia for myocardial protection. The present study assesses protection of heart, brain and kidney by RIPC under crystalloid cardioplegic arrest. The study also addresses safety and clinical outcome.
Detailed Description
Remote ischemic preconditioning (RIPC) protocol after induction of anesthesia and before skin incision 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. For myocardial molecular analyses, left ventricular biopsies are taken before induction of cardioplegic cardiac arrest and at 10 minutes after aortic unclamping during reperfusion of the myocardium.

Intervention Description

Intervention Name(s)
isoflurane+sufentanil anesthesia
Other Intervention Name(s)
Isoflurane, (2-chloro-2-(difluoromethoxy)-1,1,1-trifluoro-ethane), Forane, Sufentanil, Sufenta, (R-30730)
Intervention Description
Anaesthesia is maintained by inhaled isoflurane in concentrations 0.7-0.8 % end-tidal with additional sufentanil injected during surgery, as required. During extracorporal circulation patients receive isoflurane via a vaporizer incorporated in the extracorporeal gas supply in the same concentrations.
