Key result
Non-gated chest CT myocardial perfusion defects may help identify acute MI in acute chest pain.
Why the study?
Non-electrocardiogram-gated contrast-enhanced CT is not routinely used to evaluate for acute myocardial infarction despite its frequent use in chest pain assessment for other conditions.
Case Report (n=2)
Myocardial perfusion defects on non-gated chest CT may indicate AMI; hypothesis-generating and should not yet change practice.
Contrast-enhanced computed tomography (CT) is frequently utilized to evaluate patients who present to the emergency department with chest pain for a pulmonary or aortic disease but is not routinely used to evaluate for acute myocardial infarction (AMI). Decreased myocardial enhancement in non-electrocardiogram-gated contrast-enhanced CT has been proposed to indicate AMI. These two cases highlight the importance of carefully evaluating the myocardium for perfusion defects on non-gated chest CT scans in patients suspected of having AMI.

Jabri et al. (2022) conducted a case report in Acute myocardial infarction (n=2). Non-gated chest computed tomography was evaluated. Evaluation of the myocardium for perfusion defects on non-gated chest CT scans may help identify acute myocardial infarction in patients presenting with chest pain.
