  1. LAD system STEMI in left main or left main artery or left anterior descending artery;
  2. Non-LAD system STEMI in left circumflex or right coronary artery;
  3. DBP diastolic blood pressure; SBP systolic blood pressure;
  4. STEMI ST-Elevation Myocardial Infarction;
  5. Time to hospital: from chest pain on-set to diagnosis
