What does the medical abbreviation STEMI mean?
STEMI stands for ST-segment Elevation Myocardial Infarction. The ST in this case doesn't stand for anything; it refers to the part of the EKG tracing that is higher than usual (elevated). Patients with STEMI may benefit from treatment to restore flow to the heart muscle.
What is a STEMI?
A STEMI (ST-elevation myocardial infarction) is the deadliest type of heart attack requiring immediate emergency attention. In a STEMI, the coronary artery supplying the heart with blood is blocked, leaving part of the heart unable to receive blood. A STEMI is diagnosed with the use of an EKG (electrocardiogram). If a patient is found to have a STEMI, the patient will require immediate emergency revascularization of the heart, either through the use of clot busting medication or with the use of catheters to mechanically open up the artery.
What does the abbreviations STEM and non STEM mean in connection with ST segment?
I believe you are referring to STEMI (ST segment elevation myocardial infarction) and non-STEMI. These are two different forms of myocardial infarction - STEMI results in transmural (all the way through the cardiac muscle wall) injury, which results in elevation of the ST segment on EKG. Non-STEMI (NSTEMI), which used to be called a Non-Q-wave MI, is usually a subendocardial injury, which results in cardiac injury, but not as severe as STEMI. NSTEMIs do not have any elevation of the ST segment on EKG. These only have elevation of cardiac biomarkers on blood work.
What are EKG changes associated with an inferior STEMI?
An STEMI, or ST-segment Elevation Myocardial Infarction, is a condition in which the blood flow to the heart is blocked. This typically occurs due to rupture of a lipid plaque in the wall of an epicardial artery. This causes muscle cell death due to lack of oxygen and other substrates necessary for cell growth/maintenance. The EKG can be used to localize the likely location of the blockage by looking at changes on the EKG. An inferior STEMI is characterized by ST elevations in the inferior limb leads, leads II, III, and aVF, associated with ST depressions (called reciprocal changes) in the lateral limb leads, I and aVL. An inferior STEMI most commonly is associated with a blockage in the right coronary artery (80% of the time). Inferior STEMIs have a slightly better prognosis than anterior MIs. There is typically less heart muscle lost in association with inferior STEMI than when the MI affects the bulkier left side of the heart.
