What is non-ST elevation myocardial infarction?
Understand the Problem
The question appears to be asking about non-ST elevation myocardial infarction (NSTEMI), a type of heart attack that doesn't show the classic ST elevation on an ECG. It likely seeks information about its causes, symptoms, diagnosis, and treatment.
Answer
NSTEMI is a heart attack with partial artery blockage, no ST-segment elevation on ECG, and elevated troponin levels.
NSTEMI, or non-ST-elevation myocardial infarction, is a type of heart attack where a coronary artery is partially blocked, leading to reduced blood flow and oxygen to the heart muscle. It is characterized by elevated troponin levels and absence of ST-segment elevation on an ECG.
Answer for screen readers
NSTEMI, or non-ST-elevation myocardial infarction, is a type of heart attack where a coronary artery is partially blocked, leading to reduced blood flow and oxygen to the heart muscle. It is characterized by elevated troponin levels and absence of ST-segment elevation on an ECG.
More Information
NSTEMI is less severe compared to ST-elevation myocardial infarction (STEMI) but still requires prompt medical attention. It typically involves a partial or minor blockage which reduces blood flow but causes less immediate damage than a complete blockage.
Tips
A common mistake is confusing NSTEMI with STEMI due to their similarities as heart attacks. Remember, NSTEMI lacks ST-segment elevation on the ECG.
