NSTEMI stands for non-ST segment elevation myocardial infarction, which is a type of heart attack. Compared to the more common type of heart attack known as STEMI, an NSTEMI is typically less damaging to your heart.Is a NSTEMI the same thing as unstable angina?
NSTEMI and unstable angina are different in one fundamental aspect: NSTEMI is by definition an acute myocardial infarction, whereas unstable angina is not an infarction. Unstable angina is only diagnosed if there are no evidence of myocardial infarction (necrosis).What are the symptoms of NSTEMI?
Symptoms of NSTEMI include: shortness of breath. pressure, tightness, or discomfort in your chest. pain or discomfort in your jaw, neck, back, or stomach. dizziness. lightheadedness. nausea. sweating.How is NSTEMI diagnosed?
NSTEMI is diagnosed through a blood test and an ECG. The blood test will show elevated levels of creatine kinase-myocardial band (CK-MB), troponin I, and troponin T. These markers are evidence of possible damage to the heart cells, and are typically mild compared with STEMI. However, blood tests alone can’t diagnose a heart attack.
