Participant Flow

630 patients was the planned estimated sample size needed to test the null hypothesis. An interim analysis was scheduled at 400 enrolled patients, to verify the null hypothesis used for the sample size calculation. A p\<0.0294 was considered statistically significant to reject the null hypothesis, thus study enrollment was stopped at 411 patients.

Measure
Off Pump
Off-pump coronary artery bypass graft (OPCAB) using mandatory a stabilization device and advisable, but not mandatory, a heart positioner 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.
On-pump
coronary artery bypass graft with cardiopulmonary bypass (CPB/CAB) 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.
