Pervasive use of CT coronary angiography has been an unnecessary feature of the evaluation of patient with low-risk chest pain for the better part of a decade now. Patients were eligible by symptoms of an acute coronary syndrome, supported by ECG changes, an elevated troponin, or a history of ischemic heart disease.

Is this due to coronary occlusion? The medic activated the cath lab but was refused by the interventionalist, who did not believe that this ECG represented acute coronary occlusion. But what we truly care about is coronary occlusion, for which STEMI is just a surrogate that is only about 75% sensitive for occlusion. Look at aVF.
