Table 2 Different types of myocardial infarction
Types of myocardial infarction | Clinical classification |
|---|---|
Type 1 | Spontaneous myocardial infarction related to ischemia due to primary coronary event. |
Type 2 | Myocardial infarction secondary to ischemia due to increased oxygen demand or decreased supply, e.g., coronary artery spasm, coronary embolism, anemia, arrhythmias, hypertension, or hypotension. |
Type 3 | Sudden, unexpected cardiac death with symptoms and signs of cardiac ischemia. Death occurs before blood cardiac biomarkers able to be measured. |
Type 4a | Myocardial infarction associated with percutaneous Intervention. |
Type 4b | Myocardial infarction associated with stent thrombosis as documented by angiography or at autopsy. |
Type 5 | Myocardial infarction associated with coronary artery bypass surgery. |
