Acute myocardial infarction

Acute myocardial infarction (AMI) is also called acute myocardial infarction, which refers to acute myocardial necrosis caused by persistent and severe myocardial ischemia. Clinical manifestations often include persistent severe sternum pain, acute circulatory dysfunction, arrhythmia, heart failure, fever, white blood cell count, and elevated serum myocardial injury marker enzymes, as well as the progressive evolution of acute myocardial injury and necrosis on the ECG. According to the scope of infarction, myocardial infarction can be divided into two types: transmural myocardial infarction and subendocardial myocardial infarction. According to the course of disease development, myocardial infarction can be divided into acute myocardial infarction and old myocardial infarction.
