Brief Summary

Acute kidney injury is associated with cardiopulmonary bypass during heart surgery and its pathogenesis is similar to that of ischemia-reperfusion injury. Remote ischemic preconditioning attenuates myocardial ischemia-reperfusion injury in patients undergoing coronary bypass surgery. The investigators hypothesize that such preconditioning reduces the incidence of acute kidney injury associated with cardiopulmonary bypass.

    12 hours after surgery.

  • Incidence of acute kidney injury as defined by post-operative elevation in NGAL.

    3 hours after cardiopulmonary bypass.

Study Arms (2)
