Brief Summary:

I. Main Research Question:

  • To compare the risks and benefits of Off-pump Coronary artery bypass surgery (CABG) to On-pump CABG and to determine if one is better than the other.
  • The purpose of this pilot study is also to see the rate of recruitment with expertise-based randomization across different hospital settings.

II. Small RCT studies and meta-analyses done so far have not been able to conclusively say which of the procedure is better. A large randomized study is required to establish the risks and benefits associated with both the off-pump and on-pump CABG surgical procedures.

III. The study will look at which of the two techniques reduce major risks associated with CABG.

Arm Intervention/treatment
Active Comparator: On Pump Arm Procedure: Coronary Artery Bypass Graft with the use of CPB
Coronary Artery Bypass Graft (CABG) using median sternotomy, CPB, cardioplegia and complete cross-clamp and no associated or concomitant surgical procedures
Other Name: ON Pump CABG

Experimental: Off Pump Arm Procedure: Coronary Artery Bypass Graft without the use of CPB
Coronary Artery Bypass Graft (CABG) with no associated or concomitant surgical procedures, using median sternotomy and without CPB and cardioplegia
Other Name: OFF Pump




Primary Outcome Measures :
  1. First Co-Primary Outcome [ Time Frame: 30 days post CABG surgery ]
    The occurrence of the composite of total mortality, stroke, nonfatal MI, or new renal failure at 30 days post CABG surgery

  2. Second co-primary outcome [ Time Frame: 5 years after CABG ]
    The occurrence of the composite of total mortality, stroke, nonfatal MI, new renal failure, or repeat coronary revascularization (i.e. coronary artery bypass surgery or percutaneous coronary intervention) over 5 years after randomization.


Secondary Outcome Measures :
  1. The assessment of total costs and resources consumption at 30 days after CABG surgery [ Time Frame: 30 days after CABG surgery ]
  2. The assessment of total costs and resources consumption at 5 years after CABG surgery [ Time Frame: 5 years after CABG surgery ]

Exclusion Criteria:

Patients will be excluded if they have one of the following:

  2. contra-indications to off-pump CABG or on-pump CABG (calcified aorta, intramuscular LAD, calcified coronaries, small target vessels)
  3. concomitant life-threatening disease likely to limit life expectancy to less than 2 years,
  4. prior enrollment in this trial
  5. emergency CABG surgery (immediate revascularization for hemodynamic instability) OR
  6. redo CABG.
