Acute ST elevation myocardial infarction

Acute ST elevation myocardial infarction is a life-threatening cardiovascular emergency within the acute coronary syndrome spectrum, characterized by transmural myocardial ischemia and progressive necrosis It primarily affects adult populations with coronary artery disease and typically arises when an unstable atherosclerotic plaque ruptures or erodes, precipitating occlusive intracoronary thrombosis and a sudden cessation of downstream arterial blood flow

Defining clinical and diagnostic features include acute ischemic symptoms—most commonly severe retrosternal chest pain, pressure, or dyspnea—accompanied by persistent ST-segment elevation across contiguous leads on a 12-lead electrocardiogram and subsequent biochemical evidence of myocardial necrosis marked by elevated cardiac troponins
