Anterior Myocardial Infarction - StatPearls - NCBI Bookshelf - NIH
is a type of ST-elevation myocardial infarction (STEMI) caused by acute occlusion of the Left Anterior Descending (LAD) artery . The LAD supplies a large territory: the anterior wall of the left ventricle, the anterior interventricular septum, the apex, and often the anterolateral papillary muscle.
Patients often present with intense chest pain (sometimes described as a "clenched fist" against the sternum, or Levine's sign ), shortness of breath, cold sweats, and anxiety. anterior wall infarction
Due to the large myocardial mass at risk, AWMI carries the highest morbidity and mortality among all infarction types.
Because the LAD artery is so critical, its occlusion is frequently referred to by this serious nickname. Anterior Myocardial Infarction - StatPearls - NCBI Bookshelf
Timely Percutaneous Coronary Intervention (PCI) (stenting) is the preferred treatment. If PCI isn't available within 120 minutes, "clot-busting" thrombolytic medications may be used.
The underlying mechanism is usually acute thrombosis following atherosclerotic plaque rupture. Due to the large myocardial mass at risk,
Specific ECG criteria help localize the lesion:
