Key result
Review details coronary occlusion sites and corresponding myocardial injury patterns in evolving STEMI.
Why the study?
ECG identification of myocardial injury during acute MI has been derived from studies correlating ECG with autopsy findings, but novel imaging techniques allow reevaluation of this relationship in patients.
Updated ECG-MI correlations via SPECT/MRI may refine acute diagnosis; leaves open prospective validation before practice change.
ECG identification of myocardial injury during acute myocardial infarction (MI) has been derived from studies correlating ECG findings with autopsy findings in animal or human studies.Novel imaging techniques including SPECT and MRI provide the opportunity to reevaluate the relationship between ECG findings and myocardial injury quantified in patients undergoing AMI.This article aims to summarize our observations regarding location and terminology of myocardial injury in the course of AMI.To understand how the location of occluded artery explains the lack of blood supply to specific segments of left ventricle during an evolving myocardial infarction (MI) with ST elevation it is convenient first to review the anatomy of the heart and coronary arteries in light of the information obtained from coronary angiography and the new imaging techniques such as SPECT and magnetic resonance (MRI). WALLS OF THE HEART AND THEIR SEGMENTATION Walls of the Heart and Their NamesThe left ventricle of the heart has a conic shape and may be divided, even with no clear-cut borders, into four walls or faces.

Luna et al. (2004) conducted a review in Acute myocardial infarction with ST elevation. This review summarizes anatomic considerations and terminology regarding the correlation between the site of coronary occlusion and injured segments of the heart during evolving ST-elevation myocardial infarction.
