Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Myocardial perfusion reserve in remote myocardium, measured by cardiac MRI at baseline, 12 and 24 weeks | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Myocardial perfusion reserve in infarcted territory 2. Extracellular volume fraction 3. Capillary permeability 4. Relationship between glycaemic markers and LV perfusion parameters 5. Aortic distensibility Secondary outcome measures will be measured by cardiac MRI at baseline and at weeks 12 and 24. Secondary outcome measure 4 will also be measured at approximately 2 weeks before baseline and at weeks 10 and 22. | — |
