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.

Participant Group / ArmParticipant Group / Arm |
Intervention / TreatmentIntervention / Treatment |
|---|---|
|
Active Comparator: Ferumoxytol
Patients will be administered intravenous ferumoxytol 1 - 3 days following myocardial infarction after baseline cardiac magnetic resonance scanning.
|
One dose of intravenous ferumoxytol (4 mgFe/kg body weight at a rate of up to 1 mL/sec)
Other Names:

No Intervention: Control
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.
