Anterior wall infarction results from occlusion of the proximal LAD artery. ST-segment elevation is expected in leads V1 through V4 on the 12-lead ECG, as shown in. If the left main coronary artery is occluded, the ECG manifestations will involve almost all of the precordial leads V1through V6 and leads I and aVL (see above). These specific groups of ECG changes that help to locate the part of the heart that is infarcting are called indicative changes. A large anterior wall MI may be associated with left ventricular pump failure, cardiogenic shock, or death.
