Acute Coronary Syndromes

  • Elisabeth von der Lohe


The spectrum of acute coronary syndromes reaches from acute myocardial ischemia without ECG changes and without enzyme rise to non-ST-elevation myocardial infarction (NSTEMI; previously non-Q-wave myocardial infarction) with subsequent development of Q-waves on the ECG despite initial classification as non-Q-wave myocardial infarction (2-15% of patients with NSTEMI). Women present more often with NSTEMI (25%) than men (16%). The finding that women have a higher tendency for platelet aggregation than men correlates well with the finding that thrombi associated with NSTEMI are rich in platelets, whereas thrombi associated with STEMI are rich in erythrocytes and fibrin. This gender difference plays an important role in treatment of acute coronary syndromes.
