Abstract
Purpose of Review
This paper will review myocardial infarction with non-obstructive coronary arteries (MINOCAs) briefly, and then focus on the imaging tools that should be employed when caring for patients with suspected MINOCA.
Recent Findings
Diagnostic imaging has a critical role in assessing patients with suspected or confirmed MINOCA. The extent at which these diagnostic tests are used in any given patient will depend on the clinical acumen for the underlying condition, as well as the available resources.
Summary
There are myriad conditions that can lead to MINOCA; further testing to exclude other underlying causes of myocardial injury is crucial. Cardiovascular imaging may assist in identifying the etiological cause in cases where MINOCA remains the most likely diagnosis. A systematic approach to the diagnostic assessment will help to uncover the underlying diagnosis, guide therapy, and provide the patient and their families with appropriate feedback.
