Eligibility
Inclusion criteria
Inclusion criteria: 1. Patients (aged greater than or equal to 18 years, either sex) undergoing elective coronary artery bypass grafting 2. Left ventricular ejection fraction greater than 30% (affects likelihood of developing infection post-operatively for various reasons including increased inotropic support requirements, longer intensive care unit [ICU] stay, delayed mobilisation, and delayed removal of urinary catheters and intravenous lines) 3. Normal pulmonary function tests (affects likelihood of developing respiratory complications post-operatively)
Exclusion criteria
Exclusion criteria: 1. Patients with diabetes mellitus (affects likelihood of developing infection post-operatively) 2. Patients taking angiotensin-converting enzyme inhibitors (affects potential to reduce reperfusion injury by acting on leukocytes) 3. Patients taking steroids (more prone to developing infection) 4. Patients with chronic arrhythmias

Secondary
| Measure | Time frame |
|---|---|
| 1. CD11b and CD14 receptor expression, measured immediately pre-operatively, at aortic unclamping, two, six and 24-hours post-unclamping 2. Respiratory burst and phagocytosis of circulating neutrophils, measured immediately pre-operatively, at aortic unclamping, two, six and 24-hours post-unclamping 3. Plasma lipopolysaccharide (LPS), measured immediately pre-operatively, at aortic unclamping, two, six and 24-hours post-unclamping 4.
