What is remote ischemic preconditioning?
Remote ischemic preconditioning is a technique used to reduce the risk of myocardial injury in patients undergoing cardiac surgery. It involves briefly occluding the blood supply to the heart, either through the use of an inflatable cuff or through the use of a balloon catheter. This temporary lack of oxygen stimulates the body to produce protective proteins, which can help protect the heart from damage during surgery. Several studies have demonstrated that remote ischemic preconditioning is effective in reducing myocardial injury in patients undergoing cardiac surgery, including coronary artery bypass grafting. It is also associated with improved perioperative outcomes, such as fewer arrhythmias and less need for inotropic support.
