text: Five variables explain 90% of the<unk>  in STEMI: Advanced age,sinus tachycardia, reduced systolic blood pressure, heart failure or Killip class of two or greater, and anterior myocardial infarction location.  Two main<unk><unk>  scores are used when assessing a patient with ST elevation MI and acute coronary syndromes; the TIMI<unk>  Score (for STEMI), and the GRACE<unk>  score (for acute coronary syndrome.
option_0: ST elevation myocardial infarction risk stratification and prognosis
option_1: ST elevation myocardial infarction prognosis
option_2: Chronic stable angina risk stratification coronary angiography
option_3: ST elevation myocardial infarction assessing success of reperfusion
option_4: ST elevation myocardial infarction management of patients who were not reperfused
option_5: Unstable angina / non ST elevation myocardial infarction classification
option_6: ST elevation myocardial infarction diagnostic criteria
option_7: Chronic stable angina electron beam tomography
