Myocardial infarction generally refers to acute myocardial infarction, and myocardial infarction can be divided into 5 types.
1.1 Type 1: Type 1 myocardial infarction belongs to the ST-segment elevation type of myocardial infarction, which is mainly due to the instability of coronary artery plaque causing plaque rupture, resulting in intracoronary thrombosis and microvascular dysfunction, which leads to the occurrence of acute myocardial infarction.
2.2 Type 2: Type 2 myocardial infarction is not related to thrombus, mainly due to the imbalance of oxygen supply and demand so that the myocardium appears to be insufficient blood supply, resulting in necrosis, causing myocardial infarction, seen in patients with anemia, tachycardia, hypoxia and so on.
3.3 Type 3: Type 3 myocardial infarction is usually a sudden cardiac death after the development of myocardial ischemic chest pain, due to the rapid time of death, there is no time to collect information to determine the markers of myocardial injury.
Type 4.4: Type 4 myocardial infarction is mainly myocardial infarction associated with disease interventions, such as thrombosis within a coronary stent during coronary interventions thereby resulting in myocardial infarction.
Type 5.5: Type 5 myocardial infarction is mainly myocardial infarction associated with coronary artery bypass grafting surgery, which commonly occurs after surgery.
If a myocardial infarction occurs, immediate medical attention should be sought to minimize myocardial infarction mortality.
