Intervention(s)
All patients referred for primary elective coronary artery bypass grafting (CABG) will be considered for inclusion within the clinical trial. Trial participants will be randomised into one of three different treatment groups:
1. Positive control group in whom standard CPB is used
2. Negative control group in whom CPB is not used at all ('off pump' group)
3. Investigative group in which the mini-CPB technique is used ('miniCPB' group)

Participants will be reviewed up until they are discharged from hospital. Intervention timings are as follows:

Blood tests:
1. Pre-op (baseline)
2. Post induction
3. Start of CPB
4. 15 minutes CPB
5. 30 minutes CPB
6. 45 minutes CPB
7. 60 minutes CPB
8. 2 hours CPB
9. 6 hours CPB
10. 24 hours CPB

Cantharadin blister tests:
1. Pre-op (baseline)
2. CPB 5 hours

Myocardial tissue sampling:
1. Start of CPB
2. Before end of CPB
Primary Outcome(s)
Blood parameters of cellular stress - reactive oxygen species detection; p38 MAP kinase signalling
Secondary Outcome(s)
Supporting conventional markers of the inflammatory response will be measured including white cell count
