Extract

  • Acute coronary syndrome (ACS) results from a local reduction or cessation of blood flow in a coronary artery. This is most often caused by a sudden thrombus formation associated with rupture or erosion of an atherosclerotic plaque in the coronary artery wall.
    • In the absence of an acute atherothrombotic coronary stenosis, imbalance between the myocardial oxygen need and the availability of oxygen, and consequently myocardial ischaemia, may also be caused by conditions such as tachycardia or bradycardia, coronary spasm, hypotension, anaemia, respiratory insufficiency or other severe disease, such as sepsis.
  • Classification of ACS
    • Unstable angina (pectoris, UAP)
    • Non ST elevation myocardial infarction (NSTEMI)
    • ST elevation myocardial infarction (STEMI)
