Does stable angina have ST elevation?
ST Segment Elevation Myocardial Infarction STEMI is typified by angina at rest with evidence of transmural myocardial injury, as identified by elevated cardiac biomarkers (see Cardiac Enzymes Topic Review) and ST segment elevation on the 12-lead ECG.
When does unstable angina occur?
Unstable angina is chest pain that is sudden and often gets worse over a short period of time. You may be developing unstable angina if the chest pain: Starts to feel different, is more severe, comes more often, or occurs with less activity or while you are at rest. Lasts longer than 15 to 20 minutes.
How is silent MI diagnosed?
