Recognizing Hidden Myocardial Infarctions

Recognizing Hidden Myocardial Infarctions

An older woman arrives with ‘indigestion’ and chest pain. Her first ECG doesn’t hit STEMI millimeter cutoffs—so the cath lab isn’t activated. This case shows how occlusion MI can hide in plain sight and why expert pattern-recognition, not checkbox criteria, is what saves muscle and lives.”
