Allencherril J, et al. - Researchers compared the distribution of the myocardium at risk (MaR) in patients in the MITOCARE study presenting with a first acute ST elevation myocardial infarction (STEMI) and new ST elevation (STE) limited to V1-V4 and those with more extensive STE (V1-V6) by studying the reports of cardiac magnetic resonance (CMR) imaging, which was performed three to five days after acute infarction. MaR in predominantly apical territories and rarely in the basal anteroseptum was detected in patients with acute STEMI and STE in leads V1-V4. No evidence supported the existence of isolated basal anteroseptal or septal STEMI. For acute STEMI patients exhibiting STE in V1-V4, “anteroapical” infarction was considered a more precise description than “anteroseptal” infarction.
