E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Myocardial injury after CABG or AVR surgery using cardiopulmonary bypass |
|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To investigate the cardioprotective effect of a general anaesthetic, Propofol, when added to the cardioplegia (heart-stopping) solution used for patients undergoing isolated coronary artery bypass grafting (CABG) or aortic valve replacement (AVR) surgery using a heart-lung machine. |
|
E.2.2 | Secondary objectives of the trial |
Kidney failure is one of the most serious complications after CABG and AVR and is more common in diabetics than in non-diabetics. Blood samples taken before and after surgery will allow us to monitor kidney function. This will enable us to evaluate whether propofol has the capacity to confer further protection to diabetic patients. Interactions of treatment with diabetic status will be examined; diabetic status-specific effects will be estimated if this interaction reaches 5% statistical significance. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Inclusion criteria: Participants may enter the study if ALL of the following apply: • Male or female • Age ≥18 to ≤80 years • Having elective or urgent CABG or AVR with CPB at the BHI • Able to give full informed consent for the study |
|
E.4 | Principal exclusion criteria |
Exclusion criteria: Patients may not enter the study if ANY of the following apply: • Previous cardiac surgery • Combined CABG and valve replacement • Emergency or salvage operation • Chronic renal failure requiring dialysis • Current congestive heart failure • Left ventricular ejection fraction <30% (i.e. Poor LV Function) • Allergy to peanuts, eggs, egg products, soybeans or soy products • Already participating in another clinical (interventional) study |
|
E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome will be myocardial injury, assessed by measuring myocardial troponin T in serum from blood samples collected pre-operatively and 1, 6, 12, 24 and 48 hours post chest closure release. |

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial

This trial consists of two phases: an interventional phase (the duration of CPB) and a 3 month follow-up phase. The end of the trial is defined as the final follow-up assessment of the final patient entered into the trial. |
