2024年10月8日 · Anterior STEMI usually results from occlusion of the left anterior descending (LAD) artery and carries the poorest prognosis of all infarct territories

2024年10月8日 · Lateral STEMI is a stand-alone indication for emergent reperfusion. Lateral extension of an anterior, inferior or posterior MI indicates a larger territory of myocardium at risk with consequent worse prognosis.

2024年2月12日 · Anterior myocardial infarction (MI) occurs due to sustained ischemia caused by the occlusion of the left anterior descending (LAD) artery—this acute reduction of blood supply to the myocardium results in necrosis of the heart muscle.

2024年2月12日 · Anterior wall myocardial infarction (AWMI) occurs when there is a reduction in blood supply to the anterior wall of the heart, resulting from occlusion of the left anterior descending artery (LAD). Anterior myocardial infarction is associated with higher mortality and morbidity than other acute myocardial infarctions locations.

•Diagnostic elevation (in absence of LVH and LBBB) defined as: - New ST elevation at J point in at least 2 contiguous leads -in leads V2-V3, men >2mm, women > 1.5mm -in other chest leads or limb leads, > 1mm . Alternative causes of ST–T changes.

2019年12月16日 · Lateral STEMI criteria requires at least 1mm of ST elevation in at least two contiguous lateral leads; those not meeting this threshold are designated as NSTEMI and receive delayed reperfusion.

2023年4月21日 · High lateral STEMI is associated with a pattern of ST elevation caused by acute occlusion of the first diagonal branch of the left anterior descending coronary artery (LAD-D1). With the 4×3 display of the 12-lead ECG, the location of the most impressive ST deviations resemble the shape of the South African flag:

Lateral STEMIs generally result from the occlusion of the left circumflex coronary artery or the diagonal branch of the left anterior descending. On ECG, this is recognized by ST elevations in the lateral leads (V5-6) or the high lateral leads (I and AVL).

Explore ECG features of lateral STEMI, including isolated, antero-lateral, and infero-posterior-lateral infarctions and their vascular supply.

2021年1月5日 · Lateral extension of an anterior, inferior or posterior MI indicates a larger territory of myocardium at risk with consequent worse prognosis. Etiology. STEMI of the lateral wall is usually caused by acute atherosclerotic plaque rupture with subsequent thrombus formation in the left circumflex artery (LCx) or one of its branches (marginal branch).
