Acute myocardial infarction (AMI) is a leading cause of mortality and morbidity in the world, despite the rate having significantly declined over the past decade. The aim of this review is to consider the emerging diagnostic and clinical utility of cardiac MRI in patients with recent AMI.

Cardiac MRI has high reproducibility and accuracy, allowing detailed functional assessment and characterisation of myocardial tissue. In addition to traditional measures including infarct size (IS), transmural extent of necrosis and microvascular obstruction (MVO), other infarct characteristics can now be identified using innovative MRI techniques. These novel pathologies include myocardial oedema and myocardial haemorrhage which also have functional and prognostic implications for patients. In addition to its diagnostic utility in ordinary clinical practice, cardiac MRI has been increasingly used to provide information on surrogate outcome measures, such as left ventricular ejection fraction (LVEF) and volumes, in clinical trials. MRI is becoming more available in secondary care, however, the potential clinical utility and cost effectiveness of MRI in post-MI patients remains uncertain. Cardiac MRI is most likely to be useful in high risk patients with risk factors for heart failure (HF). This includes individuals with early signs of pump failure and risk factors for adverse remodelling, such as MVO. This review focuses on the role of cardiac MRI in the assessment of patients with AMI.
