What is an acute ST-elevation myocardial infarction?

An acute ST-elevation myocardial infarction (STEMI) is an event in which transmural myocardial ischemia results in myocardial injury or necrosis.[1]  The current 2018 clinical definition of myocardial infarction (MI) requires the confirmation of the myocardial ischemic injury with abnormal cardiac biomarkers.[2]

[1] The current 2018 clinical definition of myocardial infarction (MI) requires the confirmation of the myocardial ischemic injury with abnormal cardiac biomarkers.

What is non-ST elevation NSTEMI myocardial infarction?

Overview. Non-ST-elevation myocardial infarction (NSTEMI) is a type of involving partial blockage of one of the coronary arteries, causing reduced flow of oxygen-rich blood to the heart muscle.

Is NSTEMI an acute myocardial infarction?

A Non-ST-Elevation Myocardial Infarction is a type of heart attack, often referred to as NSTEMI or a non-STEMI. In medical terminology, a heart attack is a myocardial infarction. An NSTEMI is a less severe form of heart attack than the STEMI because it inflicts less damage to the heart.

What is the difference between ST elevation MI and non-ST-elevation MI?

STEMI results from complete and prolonged occlusion of an epicardial coronary blood vessel and is defined based on ECG criteria..NSTEMI usually results from severe coronary artery narrowing, transient occlusion, or microembolization of thrombus and/or atheromatous material.

Is NSTEMI an ischemia or infarction?

Non-ST-elevation myocardial infarction (NSTEMI) is an acute ischemic event causing myocyte necrosis. The initial ECG may show ischemic changes such as ST depressions, T-wave inversions, or transient ST elevations; however, it may also be normal or show nonspecific changes.

What is the difference between NSTEMI and STEMI?

NSTEMI is caused by a block in a minor artery or a partial obstruction in a major artery. STEMI occurs when a ruptured plaque blocks a major artery completely.

What causes a non STEMI?

The etiology of NSTEMI varies as there are several potential causes. These include tobacco abuse, lack of physical activity, high blood pressure, high cholesterol, diabetes, obesity, and family history.

What are the 4 types of myocardial infarction?
