Classification of Acute Coronary Syndromes (ACS) & Acute Myocardial Infarction (AMI)
Classification, diagnosis and definitions of acute coronary syndromes (ACS) and acute myocardial infarction (AMI) An acute coronary syndrome occurs when an atherosclerotic plaque disrupts, which results in the activation of thrombocytes and coagulation factors and ultimately the formation of a thrombus. Such a thrombus will cause occlusion of the artery. The occlusion may be complete or partial, depending on the size of the thrombus and the plaque itself. In either case, the patient will experience severe chest pain due to the abrupt reduction of coronary blood flow. Acute coronary syndromes are subdivided into STE-ACS and NSTE-ACS . STE-ACS is the acronym for ST Elevation Acute Coronary Syndrome . All acute coronary syndromes which exhibit significant ST segment elevations on ECG are classified as STE-ACS. Moreover, STE-ACS is caused by a complete coronary artery occlusion and virtually all these patients will develop myocardial infarction, which is classified as STEMI (ST Elevation Myo…
