Scientific title
Study acronym	MICASA
Study objectives	In patients with multivessel and/or left main Coronary Artery Disease (CAD), Percutaneous Coronary Intervention (PCI) compared with Coronary Artery Bypass Grafting (CABG) results in less frequent heart muscle injury, as measured by cardiac troponin I and delayed enhancement Magnetic Resonance Imaging (MRI). Secondarily, that percutaneous coronary intervention offers equivalent revascularisation compared with coronary artery bypass surgery as measured by MRI perfusion.
Ethics approval(s)	Ethics approval received from the Oxfordshire Local Research Ethics Committee on the 17th March 2006 (ref: 06/Q1606/19).
Health condition(s) or problem(s) studied	Multivessel coronary artery disease
Intervention	Coronary artery bypass grafting versus percutaneous coronary intervention.
Intervention type	Other
Primary outcome measure	The frequency of new myocardial injury following PCI and CABG as assessed by biochemical markers (troponin I) and MRI.
Secondary outcome measures	1. Total amount of new myocardial necrosis (in grams) assessed by MRI 2. Change in left ventricular function assessed by MRI
Overall study start date	01/06/2006
Completion date	31/12/2007

Participant type(s)	Patient
Age group	Adult
Sex	Both
Target number of participants	60
Key inclusion criteria	1. Patients with greater than or equal to two vessel CAD (greater than or equal to 50% stenosis) including the Left Anterior Descending (LAD), and/or a functionally significant left main stem stenosis of 50% or more 2.
