Abstract
Remote ischemic preconditioning (RIPC) is an intriguing process whereby transient regional ischemia and reperfusion episodes to remote tissues including skeletal, renal, mesenteric provide protection to the heart against sustained ischemia–reperfusion-induced injury. Clinically, this technique has been used in patients undergoing various surgical interventions including coronary artery bypass graft surgery, abdominal aortic aneurysm repair, percutaneous coronary intervention, and heart valve surgery. The endogenous opioid system is extensively expressed in the brain to modulate pain sensation. Besides the role of opioids in relieving pain, numerous researchers have found their critical involvement in evoking cardioprotective effects. Endogenous opioids including endorphins, enkephalins, and dynorphins are released during RIPC and are critically involved in mediating RIPC-induced cardioprotective effects. It has been suggested that during RIPC, the endogenous opioids may be released into the systemic circulation and may travel via bloodstream that act on the myocardial opioid receptors to induce cardioprotection. The present review describes the potential role of opioids in mediating RIPC-induced cardioprotection.
