Background ST elevation myocardial infarction (STEMI) represents a cardiac emergency. Inferior STEMI represents a dilemma for cardiologists. Methods We performed a single-centre retrospective cohort analysis of all patients admitted to our hospital from 2008 to 2020 with a diagnosis of inferior STEMI.

In fact, it read: ** **ACUTE MI / STEMI ** ** The physicians caring for the patient activated the cath lab for "STEMI". The interventionalist and cath team came to the hospital, and when the interventionalist saw the ECG, he inquired further and elicited a family history of Brugada syndrome. And it is clearly Brugada phenotype.

The cardiologist recognized that there were EKG changes, but did not take the patient for emergent catheterization because the EKG was “not meeting criteria for STEMI”. So the patient was admitted to the hospital with no plan for an angiogram. Most STEMI have peak troponin I over 1000 ng/L and most NSTEMI below that level.
