Primary Outcome Measures:
  • cognitive function [ Time Frame: preoperative, 1 week and 6 months after surgery ] [ Designated as safety issue: No ]

Estimated Enrollment: 270
Study Start Date: October 2009
Estimated Study Completion Date: March 2012
Estimated Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Remote ischemic preconditioning
Remote ischemic preconditioning will be induced by four 5-min cycles of upper limb ischemia and 5-min reperfusion with a blood-pressure cuff inflated to 200 mmHg and be performed before and after the coronary anastomosis
Procedure: remote ischemic preconditioning
Remote ischemic preconditioning will be induced by four 5-min cycles of upper limb ischemia and 5-min reperfusion with a blood-pressure cuff inflated to 200 mmHg and be performed before and after the coronary anastomosis
Placebo Comparator: control
sham placement of a blood-pressure cuff around the upper limb without inflation
Procedure: remote ischemic preconditioning
Remote ischemic preconditioning will be induced by four 5-min cycles of upper limb ischemia and 5-min reperfusion with a blood-pressure cuff inflated to 200 mmHg and be performed before and after the coronary anastomosis
