Despite the absence of significant coronary stenosis on her post-arrest cath — the ECG in Figure-1 is clearly diagnostic of an extensive anterolateral STEMI ( presumably from acute LAD [ L eft A nterior D escending ] coronary artery occlusion). The rhythm in ECG #1 is regular and supraventricular at a rate of ~75/minute.

MINOCA may be due to: coronary spasm, coronary microvascular dysfunction, plaque disruption, spontaneous coronary thrombosis/emboli , and coronary dissection; myocardial disorders, including myocarditis, takotsubo cardiomyopathy, and other cardiomyopathies. Thus, intracoronary imaging modalities are crucial in this setting. From Gue at al.

The commonest causes of MINOCA include: atherosclerotic causes such as plaque rupture or erosion with spontaneous thrombolysis, and non-atherosclerotic causes such as coronary vasospasm (sometimes called variant angina or Prinzmetal's angina), coronary embolism or thrombosis, possibly microvascular dysfunction. It is not rare.

This has been termed a “STEMI equivalent” and included in STEMI guidelines, suggesting this patient should receive dual anti-platelets, heparin and immediate cath lab activation–or thrombolysis in centres where cath lab is not available. aVR ST segment elevation: acute STEMI or not? aVR ST Segment Elevation: Acute STEMI or Not?
