|ClinicalTrials.gov Identifier: NCT00463294|
Recruitment Status : Completed
First Posted : April 20, 2007
Last Update Posted : September 16, 2016
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.

Other Name: OFF Pump
- 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
- 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.
- The assessment of total costs and resources consumption at 30 days after CABG surgery [ Time Frame: 30 days after CABG surgery ]
- The assessment of total costs and resources consumption at 5 years after CABG surgery [ Time Frame: 5 years after CABG surgery ]
