Prognostic Value of ST Elevations in Myocardial Infarction

Anterior location of STE (anterior AMI) compared with inferior or lateral, correlates with much worse prognosis and greater benefit of reperfusion therapyPatients with anterior infarction demonstrated a lower left ventricular ejection fraction on admission and after 10 days than did patients with inferior infarction, even after adjustment for infarct size, as well as a higher incidence of

ST Score

Greater height of ST segments and greater number of leads involved correlate with higher mortality and greater benefits from reperfusion therapy.ST Score refers to the total millimeters of STE in all leads combined. High ST Score correlates with higher mortalityMeasured at J point, a score greater than 12 to 13 mm for anterior AMI and greater than 6 – 9 mm for inferior AMI correlates with high
