One such cardioprotective strategy is remote ischemic preconditioning(RIPC) which describes the cardioprotection obtained from inducing ischemia in tissue or an organ remote from the heart. Our laboratory and others have established RIPC using forearm ischemia (induced by an automated cuff applied to the upper arm) as an effective cardioprotective intervention in children undergoing corrective cardiac surgery for congenital heart disease and in adults undergoing CABG surgery. In this study we investigate whether simultaneous inflation/deflation of cuffs placed on the upper arm and thigh can reduce peri-operative myocardial injury and improve short-term outcomes in patients undergoing CABG surgery.
