Several: Unstable angina is when chest pain coming from the heart increases in frequency, severity and/or intensity over the last couple of month. If pain is severe and lasts for over 20-30 minutes and pt shows in ER, The EKG may show specific changes (ST segment elevation myocardial infarction = STEMI) or subtle or no changes and the heart attack is diagnosed with blood tests (NSTEMI= non-ST elevationMI
