BACKGROUND: We assess whether remote ischemic preconditioning (rIPC) of the recipient can modify ischemia-reperfusion (IR) injury in the donor heart following orthotopic heart transplantation from brain dead donors and to examine potential mechanisms of protection. METHODS: Sixteen pigs weighing from 26 to 34.2 (mean 29.2) kg, randomized to control group (n=5), ischemic preconditioning (rIPC) group (n=6), and to receive rIPC with prior glibenclamide administration (Glib + rIPC) group (n=5) underwent orthotopic heart transplantation with the support of hypothermic (32 degrees C) cardiopulmonary bypass (CPB). The hearts were harvested from donor animal rendered brain dead by balloon compressio..
