Background Occlusion myocardial infarctions (OMIs) of the posterolateral walls are commonly missed by ST‐segment–elevation myocardial infarction (STEMI) criteria, with >50% of patients with circumflex occlusion not receiving emergent reperfusion and experiencing increased mortality. ST‐segment depression maximal in leads V1–V4 (STDmaxV1–4) has been suggested as an indicator of posterior OMI. Methods and Results We retrospectively reviewed a high‐risk population with acute coronary syndrome. OMI was defined from prior studies as a culprit lesion with TIMI (Thrombolysis in Myocardial Infarction) 0 to 2 flow or TIMI 3 flow plus peak troponin T >1.0 ng/mL or troponin I >10 ng/mL. STEMI was defined by the Fourth Universal Definition of Myocardial Infarction. ECGs were interpreted blinded to outcomes. Among 808 patients, there were 265 OMIs, 108 (41%) meeting STEMI criteria. A total of 118 (15%) patients had “suspected ischemic” STDmaxV1–4, of whom 106 (90%) had an acute culprit lesion, 99 (84%) had OMI, and 95 (81%) underwent percutaneous coronary intervention. Suspected ischemic STDmaxV1–4 had 97% specificity and 37% sensitivity for OMI. Of the 99 OMIs detected by STDmaxV1–4, 34% had |
