ST elevation myocardial infarction (STEMI) without ST elevations on 12-lead ECG
ST elevation myocardial infarction (STEMI) without ST segment elevations on 12-lead ECG This chapter covers situations in which the 12-lead ECG does not exhibit ST segment elevations , but the condition should be managed as STEMI (ST Elevation Myocardial Infarction) in terms of treatment and interventions. As discussed previously, STEMI is the result of a complete and proximal occlusion in a coronary artery, which results in transmural myocardial ischemia . The term transmural ischemia implies that the ischemia affects all wall layers – from endocardium to epicardium – in the myocardium affected by the occlusion. Transmural ischemia yields ST segment elevations on ECG . ST elevations are the hallmark of STEMI. However, there are situations with transmural ischemia that do not yield ST elevations. It is important to recognize these situations since they should be managed clinically as STEMI. The explanation for this is simple: transmural ischemia is due to a complete and proximal artery oc…
