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.
