NCT03363958

Brief Summary

This study evaluates the addition of remote ischemic preconditioning and postconditioning to standard myocardial protection protocol in patients submitted to off - pump coronary artery bypass grafting in a prospective, 1:1 randomized, double blind fashion. An interventional group will receive remote ischemic preconditioning 24-hours before OP-CABG, immediately before surgery and within 60 minutes following surgery by means of lower limb ischemia achieved by pressure cuff inflation, whereas control group will receive sham procedure perioperatively.

Study Arms (2)

RIC Group

EXPERIMENTAL

Three cycles of remote ischemic conditioning (5minutes ischemia and 5minutes reperfusion; lower leg ischemia achieved by pressure cuff inflation and deflation); First three cycles the patient will receive 24 hours preoperatively, second three cycles the patient will receive after the induction of general anesthesia but before skin incision shortly before CABG. Remote ischemic postconditioning (5minutes ischemia and 5minutes reperfusion; lower leg ischemia achieved by pressure cuff inflation and deflation) will be administered to the patient within 60 minutes after the completion of all coronary artery bypass grafts and the restoration of coronary blood flow.

Procedure: Remote Ischemic Preconditioning with Postconditioning

Control Group

SHAM COMPARATOR

Control group will receive sham procedure near identical to intervention. That will be afforded by inflation of pressure cuff on artificial leg hidden under the draping by an assistant who is not included in the research team and does not have any connection to study design and data analysis.

Procedure: Sham RIPC procedure

Interventions

Three cycles of 5 minutes of ischemia and 5 minutes of reperfusion of lower leg 24 hours, immediately before surgery and within 60 minutes after the restoration of coronary blood flow postoperatively.

RIC Group

Three cycles of 5 minutes of inflation and 5 minutes of deflation of artificial lower leg immediately before surgery and within 60 minutes after the restoration of coronary blood flow postoperatively.

Control Group
