About this trial
This is an interventional basic science trial for Myocardial Infarction focused on measuring Myocardial infarction, Magnetic resonance, Nanoparticle, Iron, Inflammation
Eligibility Criteria
Inclusion Criteria:
- Presentation with myocardial infarction (either 'ST-elevation' myocardial infarction or 'non-ST-elevation' myocardial infarction
- Troponin I ≥ 10 IU/mL at 12 hours after the onset of chest pain
- Age 18 - 80 years inclusive
Exclusion Criteria:
- Known critical (≥95%) left main stem coronary artery disease
- Continued symptoms of angina at rest or minimal exertion
- Atrial fibrillation
- Symptomatic heart failure; Killip Class ≥2.
- Hepatic failure (Childs-Pugh grade B or C) or renal failure (estimated glomerular filtration rate <25 mL/min)
- Contraindication to magnetic resonance imaging
- Past history of systemic iron overload/haemochromatosis
- Patients with known allergy to dextran- or iron-containing compounds
Sites / Locations
- Royal Infirmary of Edinburgh
- University of Edinburgh

Arm 2
Arm Type
Active Comparator
No Intervention
Arm Label
Ferumoxytol
Control
Arm Description
Patients will be administered intravenous ferumoxytol 1 - 3 days following myocardial infarction after baseline cardiac magnetic resonance scanning.
Subjects who have suffered myocardial infarction will undergo cardiac magnetic resonance imaging at the same time points as those in the 'ferumoxytol' arm but will not receive ferumoxytol or placebo.
Outcomes
Primary Outcome Measures
Change in myocardial T2* magnetic resonance signal
Change in T2*weighted myocardial signal as assessed by magnetic resonance imaging before and after ferumoxytol administration.
Secondary Outcome Measures
Change in systemic blood markers of inflammation
Change in systemic (blood) markers of inflammation over time after myocardial infarction and correlation with T2*weighted MR signal after administration of ferumoxytol.

5. Study Description
Brief Summary
The investigators wish to examine whether a novel 'nanoparticle' of iron oxide, administered intravenously allows an area of heart muscle damage after heart attack to be visualised using a magnetic resonance scanner.
Detailed Description
Using ferumoxtran (Feraheme) as a USPIO contrast agent for magnetic resonance imaging at 3 Tesla, we aim to conduct the first clinical study to examine the utility of this novel contrast agent to image myocardial inflammation after myocardial infarction.
We will test the following hypotheses in patients who have suffered recent acute myocardial infarction.
Intravenous injection of ferumoxytol accumulates at the site of myocardial infarction and this can be visualised by magnetic resonance imaging.
The spatial extent of the MRI signal change evoked by ferumoxytol in the myocardium is proportional to the volume of infarcted myocardium (as assessed by a gadolinium late-enhancement study).
Myocardial MRI signal change evoked by ferumoxytol is positively correlated with blood markers of systemic inflammation.
