Clinical, hemodynamic, and angiographic data were analyzed in relation to the presence or absence of anterior (I, aVL, and V1-6) electrocardiographic ST-segment depression in 21 patients with acute inferior myocardial infarction. All data were obtained within 12 h of onset ofchest pain. Greater than 1 mm anterior ST-segment depression was frequent (19 of 21 patients) during the early phase of acute infarction. There was a significant correlation between the single electrocardiographic lead with the greatest inferior ST-segment elevation and the single anterior lead with the greatest ST-segment depression (r = 0.87, p < 0.001), and between the sum of ST-segment elevation in the inferior leads and the sum of ST-segment depression in the anterior leads (r = 0.77, p < 0.001). The patients with >2 mm anterior ST-segment depression had a higher left ventricular end-diastolic pressure than those with ≤2 mm ST-segment depression (18.4 vs. 10.8 mm Hg, p < 0.01) only when leads I and a VL were included, but there were no clinical, angiographic, or other hemodynamic differences between the groups. These findings do not correlate anterior ST-segment depression associated with inferior myocardial infarction with a higher cardiovascular risk with regard to the variables examined.
