Residual ST elevation in V1-3 (“left ventricular aneurysm” morphology), Abnormal Q waves and T-wave inversion in I and aVL, The pattern indicates prior infarction of the anteroseptal and lateral walls, Massive ST elevation with “tombstone” morphology is present throughout the precordial (V1-6) and high lateral leads (I, aVL), This pattern is seen in proximal LAD occlusion and indicates a large territory infarction with a poor LV ejection fraction and high likelihood of cardiogenic shock and death, ST elevation is present throughout the precordial and inferior leads, There are hyperacute T waves, most prominent in V1-3, Q waves are forming in V1-3, as well as leads III and aVF, This pattern is suggestive of occlusion occurring in, Proximal LAD / LMCA occlusion has a significantly worse prognosis due to larger infarct territory size and more severe haemodynamic disturbance, The site of occlusion can be inferred from the pattern of ST changes in leads corresponding to the two most proximal branches of the LAD: the, S1 supplies the basal part of the interventricular septum, including the bundle branches (corresponding to leads aVR and V1), D1 supplies the high lateral region of the heart (leads I and aVL), ST elevation / Q-wave formation in aVL and I, ST depression ≥ 1 mm in II, III or aVF (reciprocal to STE in aVL).

Early risk stratification and treatment with anti-ischaemic (beta-blockers, nitrates), anticoagulant (heparin), and dual antiplatelet agents (aspirin plus a P2Y12 receptor inhibitor) is needed. New ischemic ECG changes. It can be distinguished from unstable angina pectoris by normal serial troponin. In most patients, the inferior myocardium is supplied by … The role of thrombosis as a cause of AMI was debated for decades in the 20th century until the 1970s, when it was clearly established as the cause of nearly all AMIs seen at autopsy and most large AMIs presenting clinically 4, 5 ( Table 1).Atherosclerosis with subsequent inflammation is the most common and most important … The following is a simplified approach to naming the different types of anterior MI.
