Emergent coronary angiographic findings of patients with ST depression in the inferior or lateral leads, or both, during anterior wall acute myocardial infarction

In conclusion, the present study indicates that there are several distinctive differences in emergent coronary angiographic findings according to the presence or absence of ST depression in the inferior or lateral leads, or both, and location of the leads showing ST depression on admission electrocardiograms in patients with anterior AMI. The coronary angiographic features of patients with this ECG finding greatly support a poor prognosis. In patients with anterior AMI, analysis of ST depression on an admission electrocardiogram should be routinely performed because it is useful in predicting coronary anatomy, the extent of infarction, and its prognosis.
