Acute myocardial infarction

Acute myocardial infarction is a life-threatening cardiovascular emergency characterized by acute myocardial cell necrosis resulting from prolonged myocardial ischemia It most commonly develops when an unstable atherosclerotic plaque ruptures or erodes within a coronary artery, provoking platelet aggregation and acute thrombus formation that severely impedes or entirely halts downstream blood flow

Patients typically present with ischemic symptoms, such as acute retrosternal chest pain, dyspnea, and diaphoresis Clinically, it is classified within the acute coronary syndromes as either ST-segment elevation myocardial infarction or non–ST-segment elevation myocardial infarction, confirmed by a dynamic rise and fall of cardiac biomarkers, primarily cardiac troponin, alongside electrocardiographic or imaging evidence of acute regional ischemia
