Myocardial infarction (MI) refers to tissue death ( infarction) of the heart muscle ( myocardium) caused by ischemia, the lack of oxygen delivery to myocardial tissue. It is a type of acute coronary syndrome, which describes a sudden or short-term change in symptoms related to blood flow to the heart. [22]

Se l'ostruzione coronarica conduce all'arresto totale del flusso sanguigno nel territorio irrorato dall'arteria interessata, provocando nell'ECG un sopraslivellamento del tratto ST, l'infarto è denominato STEMI (ST elevation myocardial infarction).
The diagnosis of myocardial infarction requires two out of three components (history, ECG, and enzymes). When damage to the heart occurs, levels of cardiac markers rise over time, which is why blood tests for them are taken over a 24-hour period.

Infarction occurs as a result of prolonged ischemia, which is the insufficient supply of oxygen and nutrition to an area of tissue due to a disruption in blood supply. The blood vessel supplying the affected area of tissue may be blocked due to an obstruction in the vessel (e.g., an arterial embolus, thrombus, or atherosclerotic plaque), compressed...
Diseases commonly associated with infarctions include: 1. Peripheral artery occlusive disease (the most severe form of which is gangrene) 2. Antiphospholipid syndrome 3. Sepsis 4. Giant-cell arteritis(GCA) 5. Hernia 6. Volvulus 7. Sickle-cell disease
Each type of infarction requires its own care. Infarction in the heart requires first aid for myocardial infarction (due to acute coronary syndrome). Infarction in the brain requires first aid for stroke (using a protocol named F.A.S.T.).

15 feb 2024 · A heart attack (myocardial infarction) is an extremely dangerous condition that happens because you don’t have enough blood flow to some of your heart muscle. This lack of blood flow can occur because of many different factors but is usually related to a blockage in one or more of your heart’s arteries .
A myocardial infarction, also and commonly called a heart attack, happens when a blood vessel in the heart suddenly becomes blocked. Blood vessels carry blood and oxygen. When a blood vessel in the heart gets blocked, blood cannot get to part of the heart. This part of the heart does not get enough oxygen.
