  Purpose

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.

Primary Outcome Measures:
  • First Co-Primary Outcome [ Time Frame: 30 days post CABG surgery ] [ Designated as safety issue: No ]
    The occurrence of the composite of total mortality, stroke, nonfatal MI, or new renal failure at 30 days post CABG surgery

  • Second co-primary outcome [ Time Frame: 5 years after CABG ] [ Designated as safety issue: No ]
    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:
  • The assessment of total costs and resources consumption at 30 days after CABG surgery [ Time Frame: 30 days after CABG surgery ] [ Designated as safety issue: No ]
  • The assessment of total costs and resources consumption at 5 years after CABG surgery [ Time Frame: 5 years after CABG surgery ] [ Designated as safety issue: No ]

  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.
