Study information

Primary study design	Interventional
Study design	Randomised controlled trial
Secondary study design	Randomised controlled trial
Scientific title
Study objectives	1. To quantify both functional and irreversible myocardial injury after CABG, with and without cardiopulmonary bypass (CPB) using multiparametric cardiac MRI at the highest spatial resolution. 2. To quantify the pathophysiological significance of bio chemically defined myocardial injury with MRI determined grams of myocardial tissue loss after CABG, with and without CPB. 3. To define the power of these new MRI indices to predict functional recovery at 6 months post-surgical revascularisation.
Ethics approval(s)	Not provided at time of registration
Health condition(s) or problem(s) studied	Surgery: Coronary artery bypass grafting (CABG)
Intervention	Patients will be randomised to receive conventional CABG or off-pump CABG (OPCABG).
Intervention type	Procedure/Surgery
Primary outcome measure(s)	1. Number and percentage of new left ventricular (LV) wall segments that are assessed as non viable by late Gd-DTPA MR imaging in both the conventional CABG and OPCABG groups 2. The distribution (regional versus global) of new non viable LV segments in both the conventional CABG and OPCABG groups 3. The extent of post operative rise in biochemical cardiac markers will be compared in the two surgical groups and will be correlated with the functional cardiac MR assessment.
