Current outcome of acute coronary syndromes: data from the Zurich-Acute Coronary Syndrome (Z-ACS) Registry

Summary Background: Acute coronary syndrome (ACS) encompasses ST-segment elevation myocardial infarction (STEMI), non-ST-segment myocardial infarction (NSTEMI) and unstable angina (UA). Although initially a syndrome with a poor prognosis, the advent of acute percutaneous coronary intervention (PCI), with novel stents and anticoagulation therapy, as well as the establishment of acute chest pain units, has to a great extent improved the outcome for patients with ACS. Objective: The aim of the present study was to assess the 30-day outcome for patients with ACS admit
