In a(n) ____ there is permanent damage to myocardial cells; however, at the time of presentation, the 12-lead ECG does not demonstrate ST segment elevations.

Question

Quizplus · Accepted Answer

A non-ST elevation myocardial infarction (NSTEMI) is characterized by permanent damage to myocardial cells without ST segment elevations on the 12-lead ECG. This is in contrast to a ST elevation myocardial infarction (STEMI) where there is also permanent damage to myocardial cells, but with ST segment elevations present on the 12-lead ECG. A cocaine-related coronary attack may lead to a NSTEMI or STEMI, depending on the extent of damage, but this is not a specific enough answer. Angina attack is not indicative of permanent damage to myocardial cells. Non-QT elevation myocardial infarction is not a recognized term.
