Compare completeness and modality of revascularization, operative and postoperative results and 1 year clinical outcomes in unselected high risk patients referred for primary coronary artery bypass surgery. Patients will be randomized to undergo off-pump coronary artery bypass graft (OPCAB) or coronary artery bypass graft with cardiopulmonary bypass (CPB/CAB).

Condition Intervention Phase

Procedure: Off-pump bypass surgery
Procedure: On-pump bypass surgery
Phase 4

Study Type: Interventional

Arms Assigned Interventions
Active Comparator: Off pump
Off-pump coronary artery bypass graft (OPCAB) using mandatory a stabilization device and advisable, but not mandatory, a heart positioner
Procedure: Off-pump bypass surgery
is a method of performing a coronary bypass operation for the purpose of treating advanced coronary heart disease while the heart is still beating normally.
Active Comparator: On-pump
coronary artery bypass graft with cardiopulmonary bypass (CPB/CAB)
Procedure: On-pump bypass surgery
is a technique that temporarily takes over the function of the heart and lungs during surgery, maintaining the circulation of blood and the oxygen content of the body.
