What is a STEMI vs non STEMI?
What is a STEMI vs non STEMI?
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.
How do you tell a STEMI from a NSTEMI?
If there is a pattern known as ST-elevation on the EKG, this is called a STEMI, short for ST elevation myocardial infarction. If there is elevation of the blood markers suggesting heart damage, but no ST elevation seen on the EKG tracing, this is known as a NSTEMI.
Which is worse STEMI or 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. However, both are heart attacks and require immediate medical care.
What is non STEMI?
Non-ST-elevation myocardial infarction (NSTEMI) is a type of [“heart attack”: link to new heart attack copy] involving partial blockage of one of the coronary arteries, causing reduced flow of oxygen-rich blood to the heart muscle.
Is PCI done for NSTEMI?
In contrast to St-segment elevation myocardial infarction (STEMI), where immediate coronary revascularization by percutaneous coronary intervention (PCI) for completely-occluded infarct-related artery is a guideline-mandated treatment, in non-ST-segment elevation myocardial infarction (NSTEMI) the optimal timing of …
What’s a non STEMI?
What qualifies as a STEMI?
Classically, STEMI is diagnosed if there is >1-2mm of ST elevation in two contiguous leads on the ECG or new LBBB with a clinical picture consistent with ischemic chest pain. Classically the ST elevations are described as “tombstone” and concave or “upwards” in appearance.
What is a non STEMI?
What causes a non STEMI?
Non-ST-elevation myocardial infarction (NSTEMI) is part of the acute coronary syndrome spectrum. Usually caused by a partial or near-complete occlusion of a coronary artery resulting in compromised blood flow to myocardium with subsequent myocardial injury or infarction as demonstrated by elevation in troponin.
