It was established that δ- and K1-opioid receptor (OR) stimulation both in vivo and in vitro promotes a decrease of infarct size/area at risk (IS/AAR) ratio during ischemia and reperfusion of heart. μ-OR activation increases a tolerance of isolated perfused heart to impact of ischemia and reperfusion but has no effect on IS/AAR index in vivo. The ORL1-receptor agonist nociceptin does not exert IS/AAR ratio in vivo. δ- and κ1-OR stimulation prevents cardiomyocyte apoptosis during ischemia and reperfiision of heart. The δ- and κ1-OR agonists mimic infarct-reducing effect of postconditioning. The OR inhibition does not impact IS/AAR index both in vivo and in vitro. The δ1- , δ2- and κ1-OR agonists are the most perspective group of opioids for creation of drugs increasing cardiac tolerance to pathogenic impact of ischemia and reperfusion.
