ST-segment elevation myocardial infarction without culprit lesion-a case report picturing the challenging interplay of epicardial atherosclerosis and coronary artery spasm.

ABSTRACT:

Background

Approximately 5-15% of patients with acute coronary syndrome have myocardial infarction with unobstructed coronary arteries (MINOCA). Guidelines recommend invasive assessments to identify underlying causes for MINOCA such as coronary artery spasm (CAS), spontaneous coronary dissection, or microvascular disease as well as non-invasive assessments in search of myocarditis, takotsubo syndrome, or cardiomyopathies.

Case summary

A 54-year-old male patient presented with ST-segment elevation myocardial infarction (STEMI). Upon arrival, ST-segment elevation and symptoms had ceased. Emergency coronary angiography showed diffuse epicardial atherosclerosis with stenoses in the distal left anterior descending coronary artery (LAD) and second diagonal branch (D2); however, no
